Issue Overview
Dear Subscriber:
I hope that the summer has been a good one for you. If your
child is back in school now, I hope that the year is off to a
good start.
This month's issue of ADHD RESEARCH UPDATE
reviews
several new studies that I found to be quite interesting. The
first -
Is stimulant medication overprescribed? - is one you
may
have seen carried in the popular media. In this study, the authors
examine the rate of stimulant medication treatment relative to the
diagnosis of ADHD in an entire county of western NC. An initial
examination of the results of this study suggests that stimulants
are being widely overprescribed, and this is the way I have seen
this investigation portrayed. In fact, however, when one examines
the study more carefully, the reasonableness of this conclusion
becomes more suspect. Instead, it appears that undertreatment
-
especially of females - is also a very important issue to consider.
Next, preliminary reports of a new medication called Concerta
are presented. You may have heard of Concerta, which is
basically methylphenidate with a unique delivery system that
allows for effective symptom management with only
once-a-day dosing. There are many children for whom this
medication may be a tremendous improvement, as the requirement
for multiple doses per day can lead to compliance problems. This
is especially likely to the true for adolescents who often balk at
having to take medication while at school. This does not mean,
however, that Concerta should be used for every child with
ADHD who is currently on meds, and some guidelines for
thinking about the issue of switching are discussed.
The next article - Do boys with ADHD overestimate their
social competence? - reviews an interesting experimental
study in which a possible non-behavioral explanation for the
social problems experienced by many children with ADHD
is explored. The authors of this study report that boys with
ADHD often believed they were more successful socially than
was actually the case, and that they also tend to disavow
responsibility for the social outcomes - whether positive or
negative - that they experienced. This may prevent them from
accurately recognizing how others are perceiving them, and
thereby reduce their motivation to alter their behavior. Although
this would not be true certainly for all children with ADHD, these
data have implications that are important for parents and
practitioners to be aware of.
The final article - Parent and child report of sleep problems
in children with ADHD - provides another interesting
look
at the issue of sleep difficulties in relation to ADHD. This
study adds to current knowledge on this topic by obtaining the
perspective of children themselves, rather than relying solely
on the reports of parents. An interesting finding is that children
with ADHD were more likely than peers to report fears and
anxieties associated with going to sleep, which can certainly
have important clinical implications for some children.
Detailed accounts of these studies are provided below. I hope
you enjoy the issue and find information in here that is useful
to you.

* IS STIMULANT MEDICATION OVERPRESCRIBED?
An article published in the recent issue of the
Journal of the
American Academy of Child and Adolescent Psychiatry
(JAACAP) is sure to add to the ongoing controversy
about
the possible overprescription of stimulant medication.
Upon
initially reviewing this paper, a clear case
for dramatic overuse
of medication to treat ADHD seems evident.
A closer
inspection of the results, however, suggests
that the issue is
not so straight-forward. This is an important
study that will
probably get plenty of press, so I wanted to
include a careful
review of it in ADHD
RESEARCH UPDATE.
In this paper (Angold, A. et. al., (2000). Stimulant
treatment
for children: A community perspective. JAACAP,
39, 975-
984.) the authors examine the use of stimulant
medication in
relation to a research-derived diagnosis of ADHD
in a community
sample of children. Participants in this
impressive study were a
representative sample of 4500 children ages 9
to 16 from 11
different counties in western North Carolina.
Each year for
4 years, these children and their parents were
administered
structured psychiatric interviews to enable careful
diagnoses -
not just of ADHD, but of a variety of psychiatric
conditions -
to be made. Parents were also asked to
provide information
on any treatment the child had received during
the prior year
for a mental health condition, including treatment
with stimulant
medication for ADHD. In addition, the teachers
of these children
were asked to complete a standardized behavior
rating scale each
year. Ratings from multiple teachers were
collected whenever
possible.
A study of this magnitude is an enormous undertaking,
and the
overarching objective was to obtain reliable
estimates of the
frequency of a wide variety of psychiatric problems
within a
community sample of children, the kinds of services
for psychiatric
problems that children receive, and the match
between the rate of
problems and available services. In this
particular paper, however,
the authors were interested in a much more circumscribed
question.
Specifically, they were interested in how the
rate of stimulant
medication treatment in this community compared
to the community
rate of ADHD. Their data would enable them
to answer to the
these important questions:
1). What percentage
of children with a verified diagnosis of
ADHD are actually being treated with stimulant
medication?
Because current evidence suggests that carefully
conducted treatment
with stimulant medication is an effective treatment
approach - although
many children require additional interventions
as well - the answer to
this question provides a crude indication of
how often children
with ADHD are receiving an empirically supported
treatment.
2). How often
are children without a verified diagnosis of
ADHD being treated with stimulant medication?
To my knowledge, even the most ardent supporters
of medication
treatment for ADHD do not endorse its use for
children without
a carefully established ADHD diagnosis.
Thus, the answer to this
question provides some indication of how often
stimulants are
being prescribed inappropriately.
Note: An important issue that was not really
possible to address in
this study concerns the manner in which medication
treatment is
carried out. One can not assume that a
child with a clear
diagnosis of ADHD who is prescribed medication
is receiving
appropriate treatment. This is because
medication treatment in the
community is often carried out in a far from
optimal manner, and is
often not combined with behavioral interventions
that may be
necessary.
RESULTS
What is the rate of ADHD in this community sample?
The initial data presented by the authors concerns
the rate of
ADHD diagnoses in this large and representative
community
sample. Of the children interviewed, 3.4%
were regarded as
having a definite diagnosis of ADHD. Boys
(5.3%) were more
likely to have a definite diagnosis than girls
(1.5%). An additional
2.7% had sufficient impairment from ADHD to warrant
the
diagnosis of ADHD-Not otherwise specified.
Boys were
over represented in this group as well (i.e.
4.4% vs. 1.0%).
(Note: ADHD-NOS is the term applied when
a child does not
meet complete diagnostic criteria for ADHD but
still has a number
of symptoms that are causing impairment.
For a review of
current official diagnostic criteria click here.)
Overall, therefore,
6.2% of the population were diagnosed with either
definite ADHD
or ADHD-NOS. This prevalence rate is consistent
with what
has been found in other studies, and represents
the % of the
population who were found to meet diagnostic
criteria for
ADHD at any time during the 4-year study.
Note: One problem with the diagnostic procedure
used in this
study that will have important implications to
be discussed below
is that diagnoses were based solely on the parent
interview data.
Thus, even though behavior rating scale data
was collected from
teachers, ADHD diagnoses were assigned strictly
based on what
parents reported. The authors explain this
choice by noting that
they did not have full diagnostic information
from teachers, and
that parent reports are used for diagnosis in
most "real world"
clinic settings.
Although these points are well taken, the absence
of teacher-
reported information being used in the diagnostic
process would
almost certainly result in a lower prevalence
rate than
if it were included. This is because teachers
often observe ADHD
symptoms that parents do not. I thus think
it is quite likely that the
prevalence rates reported above underestimates
the true rate in
the community.
What is the rate of stimulant medication treatment
in this
community sample?
At one or more points during the 4 years of this
study, 7.3%
of the children had been treated with stimulant
medication.
This is over twice the number of children who
received a
definite diagnosis of ADHD (although the caveat
noted above
about the probable underidentification of ADHD
is an
important one). It is also slightly higher
than the combined
rate of ADHD and ADHD-NOS.
This overall rate, however, does not tell us whether
the children
receiving medication were the ones who actually
had ADHD.
Instead, it just indicates the percentage of
children in the
community who had received stimulant medication.
When
the authors examined this important question,
they found
that approximate percentage of children treated
with stimulants
was 72%, 23%, and 5% for children with ADHD,
ADHD-NOS,
and without ADHD or ADHD-NOS respectively.
Because this last group is so much larger than
the others in
terms of absolute numbers (remember, the vast
majority of
children had no ADHD diagnosis), it means that
at any given
time, the number of children without ADHD in
this community
who were being treated with stimulants was greater
than the number
of children with ADHD who were being treated.
The authors
estimated, in fact, that 57% of the children
who were treated with
stimulants did not have ADHD or even ADHD-NOS.
It is also
interesting to note that boys with ADHD were
far more likely to be
treated with medication than girls with ADHD
(80% of ADHD boys
vs. only 41% of ADHD girls).
What do these numbers say about the overtreatment
vs.
undertreatment problem?
One unfortunate problem with data such as this
is that it is
relatively easy to focus on numbers that support
the point one
wants to make and ignore the bigger picture.
It is thus
important to carefully consider the implication
of these
findings.
First, in regards to possible undertreatment,
these data show
that almost 30% of children with a definite diagnosis
of ADHD
did not receive stimulant medication treatment
at any point
over the 4-year study period. One possible
explanation for
this is that although these children were diagnosed
with ADHD
in the study, they were never diagnosed appropriately
by their
physician in the community. In this study,
diagnostic information
was not routinely shared with parents nor were
treatment
recommendations made by the research staff.
So, it is quite
possible that many children who clearly met diagnostic
criteria
for ADHD were simply never diagnosed by their
own health
care provider, and thus never received medication
treatment.
It is also possible that many of these children
were diagnosed in
the community and parents were informed of this
treatment option
but elected not to consider it for their child.
Alternatively, some
parents of diagnosed children may never have
been appropriately
informed of the possible benefits of medication.
This information
would be very interesting to have but was not
presented in the
paper.
One conclusion that can be made with greater certainty,
however,
concerns the undertreatment of girls with ADHD.
Recall that girls
with confirmed ADHD were half as likely as boys
with ADHD to be
treated with medication. Because medication
has been shown to
be an effective treatment, the fact that girls
with ADHD are less
likely than boys to receive it is problematic.
My hunch is that the
reason for this finding is the previously shown
fact that physicians
are prone to miss the diagnosis of ADHD in girls.
In other words,
fewer girls with ADHD were treated with meds
because fewer
girls who were diagnosed with ADHD by the researchers
ever
received this diagnosis by their own physician.
This, of course,
is just speculation, but is seems plausible.
It would be interesting
to know if this were true, and even more interesting
to know
whether girls were less likely than boys to receive
meds even when
their physician had diagnosed them with ADHD.
Despite these uncertainties, the bottom line is
that many children with
ADHD - and the majority of girls with ADHD -
were not receiving
medication treatment in this community.
Of course, whether or not
this is a problem depends on the value one places
on this treatment
modality. It is also important to recognize
that because the reliance
on parent data only to make diagnoses probably
resulted in a number
of children with ADHD going undiagnosed, the
actual number of
ADHD children who were not treated is probably
higher - and may
have been substantially higher.
What about the overtreatment problem? As
noted above, about 5%
of children without ADHD were reported to have
received medication
treatment. In fact, at any given time,
more children without ADHD
were on medication than children with ADHD.
Certainly, this is an important problem.
The magnitude of this problem,
however, may not be quite as great as it initially
appears. One very
interesting comparison the authors made looked
at the children without
ADHD or ADHD-NOS who were receiving stimulants
and those
who were not. They found was that although
the parents of
children in both groups reported few if any ADHD
symptoms, the
interviewers observed ADHD symptoms in 50% of
the children who
were treated with meds compared to only 10% in
those not treated.
In addition, the ADHD symptom ratings from teachers
was actually
higher in the non-ADHD children who were being
treated than in the
children with definite ADHD.
So, in many cases, children who did not have ADHD
according to
their parents were clearly displaying high levels
of ADHD symptoms
according to their teachers. These
were the children in the study
"without ADHD" who were likely to be receiving
medication treatment.
One would imagine that at least some of these
children would have
turned out to have a confirmed diagnosis of ADHD
if parent and
teacher information was combined - a procedure
not implemented
in this study for the reasons noted above.
Thus, the number of
children treated with meds who did not have ADHD
is probably
fewer than what is reported in this study.
(Note: It is important to emphasize that
the data presented above,
although representative of the community in which
they were
collected, still applies to this one community.
To what extent
similar patterns would be found in other communities
across
the county is unclear, as it is well-know that
prescribing patterns
can vary greatly across physicians.)
SUMMARY
It would not be surprising if the results of this
study are presented
in the media as prima fascia evidence that children
are often treated
with stimulants for "no good reason". Unfortunately,
this practice
certainly goes on, and it seems inevitable that
far more children
receive stimulant medication than truly need
it. One only has to
consider studies reviewed in prior issues of
ADHD
RESEARCH
UPDATE in
which it was reported that as many as 20% of
white male 5th graders in some communities are
receiving
medication to know that this must be the case.
What can get lost in the understandable concern
over such
findings is the equally concerning fact that
large numbers of
children with ADHD are never identified or treated
in any way
other than being punished repeatedly for their
behavior. In
the current study, almost a third of all children
with ADHD never
received medication. For females with ADHD,
the odds of
being treated with meds were less than 50/50.
Once again,
this is a problem only to the degree that one
believes stimulant
medication to be a safe and effective treatment
for ADHD.
However, because research conducted to date indicates
that
well conducted medication treatment is probably
the most
effective treatment for ADHD currently available,
it is not
unreasonable to be concerned about this finding.
The "safest" conclusion one can make from data
such as this
is that at any given time, there are probably
thousands of
children in the US who are treated with stimulants
they
probably don't need and thousands of children
with ADHD
who could benefit from stimulants but not receiving
them.
The solution to this problem is to increase the
ability of
community physicians to evaluate children for
ADHD in
a careful and systematic manner, and to help
them prescribe
medication when appropriate in a systematic manner
that is
likely to provide the maximum possible benefit.

* CONCERTA: A
NEW MEDICATION FOR TREATING
ADHD
For parents who have a child taking medication
to help
manage ADHD symptoms, a frequent source of difficulty
is the need for multiple doses each day.
Among children who
take Ritalin (the generic is methylphenidate),
a second dose
while at school and a third dose in the late
afternoon
is often necessary to provide good control of
symptoms
over the course of the day. Administration
during the
school day can be associated with complications,
and is
often a source of concern or embarrassment for
the child.
As children move into adolescence, this can frequently
lead
to a refusal on the part of the teen to continue
on meds, even
though medication may still be necessary to help
manage the
child's symptoms and help with behavior and academic
performance.
Although sustained release forms of Ritalin last
longer and can help
somewhat with this problem, the additional duration
of benefit
provided by a single dose varies substantially
across children.
Adderall, a more recently approved stimulant
medication for
treating ADHD, also has a therapeutic effect
that lasts longer
than Ritalin, and many children on Adderall can
get by with
a single dose during the school day.
Even with Adderall,
however, a second dose in the afternoon is often
required.
Recently, a new medication called Concerta was
approved
by the FDA for the treatment of ADHD and is expected
to be
widely available very shortly. Concerta
is simply methylphenidate
in which a unique and patented system is used
to maintain a
smooth and optimal level of medication in a child's
system
throughout the entire day. In fact, the
benefits of Concerta are
reported to persist throughout the school day
and into the evening.
This would make the administration of medication
to children with
ADHD much more convenient, and should help to
eliminate many
of the problems associated with multiple daily
doses.
Results of a study on the effectiveness of Concerta
was presented at
the May meeting of the American Academy of Pediatrics.
This study
was supervised by Dr. James Swanson from the
University of California
at Irvine, a leading researcher in the field
of ADHD. His work
has included studies of both medication and behavioral
treatment so
I believe he has a broad perspective on the treatment
of ADHD.
Participants in this study were 64 6-to-12 year
old children with a
confirmed diagnosis of ADHD, all of whom were
being treated
currently with methylphenidate. During
the study each child
received 3 different treatments: methylphenidate
on their regular
dose 3 times per day, Concerta once per day,
and a placebo. Each
treatment was received for 7 consecutive days
and neither parents,
teachers, nor children were aware of what treatment
the child was
receiving each week. At the end of each
week, standardized
behavior rating forms were completed by parents
and teachers,
as were ratings of possible adverse side effects.
(To be sure
that participants would not know when the child
was on the
Concerta, one "real" dose and 2 placebo pills
were given each
day. This way, 3 "doses" each day were
required during every
week of the trial.)
Results indicated that both Concerta and the 3
daily doses of
methylphenidate resulted in significantly lower
symptom ratings
compared to placebo from both parents and teachers.
The two
medications, in contrast, did not differ from
one another. This
means, of course, than a single daily dose of
Concerta was as
effective as 3 doses of regular methylphenidate
in managing the
symptoms of ADHD. Side effects were reported
to be mild
and were quite similar to regular methylphenidate.
Only 3 side
effects were reported to occur in over 2% of
the children - abdominal
pain, headaches, and fever - and these all occurred
in less than
5% of the participants.
Overall, parents reported preferring Concerta
to the methylphenidate
used during the study and to the treatment their
child had been receiving
prior to the study. Remember, this preference
for Concerta was reported
even though during the study, all children received
3 doses per day.
(During the time they were receiving Concerta,
it was just the first
dose each day that was real medication.
The second two "doses"
were actually placebos.) The most likely
reason for this, I think, is
that with Concerta, the smoother release of medication
throughout
the day may have resulted in more consistent
management of
symptoms than regular methylphenidate.
A SECOND STUDY OF CONCERTA
I also recently saw a press release describing
a second study
involving Concerta. A larger number of
participants - 407
children with a confirmed diagnosis of ADHD -
were included and
these children were followed over the course
of an entire school
year. Children in the study ranged in age
from 6 to 13 and had
previously completed a short-term controlled
study that included
regular methylphenidate, Concerta, and placebo
conditions.
In this second study, children were assigned
to one of three dosing
levels - 18, 36, or 54 mg. - based on the dose
level administered
in the short-term study. Data on the results
of this study are not yet
published in a peer reviewed journal, but were
presented at a recent
meeting of the American Psychiatric Association.
During the course of the year, children were evaluated
with varying
frequency using standardized ratings of behavior
and attention.
Results indicated sustained improvement in behavior
and attention
over the course of the year. In a global
assessment of treatment
effectiveness obtained at the end of the study,
over 60% of teachers
and 84% of parents rated treatment as good or
excellent. Thus,
it appears from these results that the once per
day treatment with
Concerta provide effective symptom management
over the course
of the entire year. Side effects reported
were similar to those
that have been reported before for regular methylphenidate.
Note: I was previously advised by a subscriber to note when studies
reporting effective medication treatment have been funded by
the pharmaceutical company who manufactures the drug. I
believe this is the case here. While some would argue that this
means the results are suspect, I do not personally feel this to be
correct.
Such medication studies are typically conducted by independent
academicians, and I have several colleagues who are routinely
involved in pharmaceutical trials. The clinic where they work
is paid by
the drug company to conduct the study, but this does not influence
-
in my opinion - the integrity with which the data is collected and
reported.
It is also important to be aware that there is not really an alternative
to the drug company paying for such studies. These studies are
necessary to obtain FDA approval and no one else is going to fund
studies of a medication that has not yet been approved by the FDA.
Should you make the switch to Concerta for your child?
The answer to this question is not necessarily
straight forward.
If your child is currently taking another medication
that is
working well, and having to take multiple doses
each day is
not a problem, there may be no good reason to
switch. Basically,
why tinker around if everything is going fine?
If you and your child's physician do elect to
try Concerta, you
should be aware that because Concerta is methylphenidate
that is
being delivered in a way that maintains a steady
dose over the entire
day, children doing well on regular methylphenidate
should do well
on Conerta. If your child has been on another
type of medication
such as Adderall or Dexedrine, however, one could
not necessarily
assume that Concerta would be equally effective
in managing
ADHD symptoms. It is possible, for example, that
your own child's
symptoms would not be managed as well if the
switch were made.
If your child's current medication seems to be
working well,
but he/she requires multiple doses each day which
is resulting
in compliance problems, than discussing a switch
to Concerta
with your child's physician should be considered.
As noted above,
the need for only once-a-day dosing may be especially
helpful
with teens who often balk at needing to take
medication during
the school day.
If your child is not currently taking medication
to manage ADHD
symptoms, but this is something you are considering,
it may
be worth asking your doctor about starting out
with Concerta.
So far, it appears to be as effective as regular
methylphenidate in
managing ADHD symptoms, and to produce no additional
side
effects. The caution to keep in mind, however,
is that it has not
yet been studied as extensively as regular methylphenidate
or even
Adderall, and there can be no guarantee that
these initially encouraging
results will hold up to further study.
There is no compelling
reason, however, to think that they will not.
My own personal
expectation is that they will.
One other issue that I think is important in the
decision to use
Concerta is whether a child really needs medication
throughout the
entire day, which is what Concerta provides.
For example, some
children require medication primarily to assist
with academic functioning
during the school day, and really do not need
it except for these times.
For these children, a single morning dose
of methylphenidate or Adderall
may be all they require. In such instances,
it seems like a
legitimate question to ask is whether Concerta
would really be preferable.
In summary, although Concerta appears like it
will be an extremely helpful
and valuable new medication for many children
with ADHD, it is not
necessarily going to be the best choice for everyone.
As always,
carefully evaluating what is required by each
individual child is still
required to make the best decisions about medication.
* DO BOYS
WITH ADHD OVERESTIMATE THEIR
SOCIAL COMPETENCE?
One of the most common problems for children with
ADHD is
the difficulty they experience in relationships
with peers. In fact,
some authors have noted that social problems
are so pervasive
among ADHD children that they ought to be included
in the
diagnostic criteria. Of these problems,
rejection by peers is the
most widely documented and the source of greatest
concern.
The reason for this concern is that a number
of studies have
linked peer rejection in childhood to a number
of adjustment
problems later in life.
Why do children with ADHD tend to have such consistent
difficulty in establishing friends and getting
along with peers? One
contributing factor is clearly the behavior that
is closely
linked to ADHD symptoms. Just as such behavior
can be aversive
to adults, it can be equally aversive to children.
Another factor
that may contribute to the social problems of
ADHD children is
the that may they frequently misperceive the
quality of their
interactions with peers. Some researchers have
suggested that
children with ADHD are prone to overestimate
how much peers
like them, and to be relatively unaware of how
they actually
come across. In addition, boys with ADHD have
been
shown to be less likely than peers to accept
personal responsibility
for social failures. If children with ADHD
have difficulty recognizing
their problems, and tend to attribute problems
they do recognize
to something other than themselves, motivation
for corrective
action could be quite low. This raises
the possibility that a
positive and illusory bias could be as important
an impediment to
developing better peer relations as are behavioral
factors.
This interesting hypothesis was examined in a
study published recently
in Child Development, perhaps the leading
journal in developmental
psychology. In this study (Hoza, et al.,
(2000). Attention-deficit/
hyperactivity disordered and control boys' responses
to social success
and failure. Child Development, 71,
432-446.) the authors looked at
how boys with and without ADHD responded to experiences
of social
success and social failure. They were especially
interested
in how accurate boys with ADHD were in their
evaluation of their
interactions with peers, and the degree to which
they assumed personal
responsibility for their positive and negative
social experiences.
Participants in this study were120 7 to13-year-old
boys with ADHD (average
age was 9.5 years) and 65 boys without ADHD who
served as control
subjects. Unfortunately, no girls were
included in this study, which the
authors clearly recognize as a limitation.
The ADHD boys were
participating in an intensive 8-week summer treatment
program. At the
time of the study to be described below, children
were not receiving
medication.
The procedure used in this study was interesting
and a bit
complicated. The study used a social acquaintance
task in a controlled
laboratory setting in which participants interacted
briefly with a child
whom they did not know. Prior to this interaction,
each participant was
told that the experimenter needed his help in
recruiting a new child to
participate in the summer camp program next year.
He was thus instructed
to "try and get him to like you" and "try to
talk him into coming to camp
here".
Unbeknownst to the subjects, however, the unfamiliar
child they were
introduced to was actually a "confederate"
of the experimenter who had
been instructed to act in particular ways.
In one condition, the confederate
was instructed to behave in a friendly manner
towards the child and to
express his interest in attending the camp next
summer. Thus, this
condition was intended to provide study participants
with a clear
experience of social success. In the other
condition, confederates
were told to behave in the opposite manner.
They behaved in ways that
clearly indicated they were not enjoying themselves
and expressed a strong
desire not to attend camp the following summer.
The intent was to
create an experience in which children would
feel they had not been
successful in getting the other child to like
them or to want to attend camp.
(Note: After these negative interactions, children
were always provided
with a positive social experience with that same
confederate before leaving
to ensure that all interaction sessions ended
on a positive note.)
Each child participated in both the success and
failure interaction task.
The different conditions occurred on separate
days during the summer.
The order of these tasks - i.e. success followed
by failure or failure
followed by success - occurred equally often
for ADHD and control
children.
After both the success and failure interaction,
boys were asked a
number of different questions to learn about
their perceptions
for what had occurred. One set of questions
focused on having the
boys evaluate their performance by asking them
to rate how well
they did at getting the other child to like them
and to want to attend
the camp. They were also asked how much
they liked the boy they
had just met. A second set of questions
asked the boys to explain
why they believed they had either succeeded or
failed on the task.
These explanations focused on ability (e.g. "I
failed because I'm not
good at getting kids to like me."), task difficulty
(e.g. "It's not hard to
get kids to want to come to a camp like this."),
effort (e.g. "He didn't
like me because I didn't really try that hard
to make him like me."),
or luck ("I guess it was just lucky that he liked
me."). As you can
see, these 4 types of attributions (i.e. explanations
for what happened)
either involve something about the child himself
(i.e. ability and effort
attributions) or something that has little to
do with the child himself
(i.e. task difficulty and luck).
In addition to asking boys these questions, their
interactions with
the confederate were videotaped so their behavior
during the sessions
could later be studied and analyzed. Boys'
behavior was rated by
adult raters who were unaware of whether or not
the child being rated
had ADHD. They were asked a number of different
questions about
each boys' performance during both the success
and failure interaction tasks.
Ratings of individual questions were collapsed
to provide summary
scores for 2 general factors: how effective each
boy was at the task
(i.e. how effective was their behavior for getting
another child to
like them to want to attend camp) and how frustrated
and helpless
each boy appeared during the interaction.
RESULTS
The results of this study were quite interesting.
As expected, boys
with ADHD were rated by observers as being less
effective than
control boys in being able to act in ways that
would get the other
child to like them and want to attend the camp.
Despite being seen
as less effective, however, they were also regarded
as appearing
less frustrated and helpless. This was
true regardless of whether the
confederate was acting towards them in a friendly
or unfriendly
manner.
One reason ADHD boys may have appeared to feel
less frustrated
and helpless is that in their own self-evaluations,
they rated themselves
as doing significantly better at accomplishing
the goals than control
boys. Thus, even though they were judged
by objective observers
to be less effective, they rated their own performance
as more
effective. This suggests that boys with
ADHD are prone to overestimate
the success of their social overtures towards
peers, and may also
misperceive others' feelings towards them.
Interestingly, despite reporting that they were
more successful
than they actually were, boys with ADHD tended
not to give themselves
credit for that success. In the condition
where confederates had
been instructed to act in a friendly manner,
ADHD boys were more
likely than controls to say that they succeed
either because the task
was an easy one or because they were lucky.
After failing in the
task, however, (i.e. the condition in which confederates
were not
friendly) they were less likely than controls
to attribute the failure
to their own lack of effort. Together,
these findings suggest that
boys with ADHD may have a tendency to deny responsibility
for
both their social success and social failure.
SUMMARY AND IMPLICATIONS
This study adds to our understanding of the social
difficulties of
boys with ADHD by documenting what may be important
non-
behavioral reasons for their problems.
The results of this study
suggest that boys with ADHD tend to overestimate
their actual
social competence, are less prone to experience
frustration and
helplessness in social situations, and tend to
attribute their social
successes and failures to factors outside themselves.
One can
imagine how this combination would not promote
a child's motivation
to act differently towards peers in an effort
to improve one's social
situation. After all, if you overestimate
how well you are doing,
experience little social frustration, and tend
not to feel responsible for
what happens anyway, then why bother trying to
change?
Despite the interesting nature of these results,
it is important to
note the limitations of a study such as this.
First, as noted above,
because only boys were included as participants
there is no way
of knowing whether these findings would generalize
to girls with
ADHD. It is probably safer to assume that
they do not until
a similar study with females is conducted.
Second, although the findings reported above characterized
boys
with ADHD overall, one should not take this to
mean that every
boy with ADHD would display a similar pattern.
In fact, that
would certainly not be the case. Many children
with ADHD tend
to feel quite negatively about their social competence
and to
blame themselves - often unfairly - for the difficulties
they
experience. What is important, therefore,
is to try and determine
whether the issues highlighted in this study
are applicable to
an individual child, and if so, to develop an
appropriate way
for addressing these issues. Doing this
effectively is likely to
require high levels of sensitivity and skill,
and may best be
approached in consultation with an experienced
child mental
health professional.
It is also important to emphasize that the pattern
of results obtained
were found after boys with ADHD had a relatively
brief encounter
with an unfamiliar child. Thus, the tendency
to overestimate success
and deny responsibility for both positive and
negative outcomes
may be restricted to new relationships and may
not necessarily
persist in situations where children know each
other for a longer
period of time. For example, one can imagine
how an initial
tendency to believe that one is better-liked
by a child than is
actually the case would eventually crumble in
the face of repeated
negative feedback. Of course, that would
still not mean that these
findings are not important in the social problems
of some boys
with ADHD. This is because misreading the
reality of a relationship
early on can eventuate problems that make developing
a positive
relationship with a new peer less likely.
Finally, this study was conducted when children
were not on
medication. As medication is the most commonly
prescribed
treatment for ADHD, it would be interesting to
know whether
similar results would be obtained in ADHD children
who were
medicated.
In summary, this study should be regarded as in
interesting initial
effort to obtain a more comprehensive understanding
of the social
difficulties experienced by many children with
ADHD. Additional
research addressing these interesting issues
is certainly required to
help translate these findings into more effective
interventions. In
the meantime, the study acts as an effective
reminder to parents
and practitioners of how important it is to attend
to the peer
relationships of children with ADHD, and provides
interesting
insights about issues to consider when trying
to help a child with
ADHD become more successful with peers.

* PARENT AND CHILD
REPORT OF SLEEP PROBLEMS
IN CHILDREN WITH ADHD
In prior issues of ADHD RESEARCH UPDATE studies
in which
sleep difficulties among children with ADHD were
investigated have
been reviewed. These studies have
found that parents of children with
ADHD are more likely to report sleep difficulties
in their children. This
is an important finding for two reasons.
First, some investigators have
suggested that in some cases, significant sleep
difficulties may explain
the ADHD symptoms that a child is displaying.
In other words, some
apparent cases of ADHD may reflect an undiagnosed
and untreated
sleep disorder. Second, even when this
is not the case, inadequate
sleep could exacerbate symptoms in a child who
truly has ADHD.
Addressing these sleep problems appropriately
could thus play an
important role in reducing some of the child's
difficulties.
In a recently published study in the Archives
of Pediatric and Adolescent
Medicine interesting new data ion this
important issue is presented
(Owens, J. eta., (2000). Parental and self-report
of sleep in
children with ADHD. Archives of Pediatric
and Adolescent
Medicine, 154, 549-555.) This study
adds to existing knowledge in
this area because it provides information about
sleep difficulties
from children with ADHD themselves, rather than
relying exclusively
on the report of their parents.
Participants in this study were 46 unmedicated
school-age children
(mean age 89 months; 74% male) diagnosed with
ADHD who had
been screened for severe symptoms of a sleep-related
breathing
disorder and 46 matched controls.
None of the ADHD
children were reported to have a comorbid diagnosis
of depression
or an anxiety disorder, and very few were reported
to have an
additional disruptive behavior disorder (i.e.
Conduct Disorder or
Oppositional Defiant Disorder). The relative
absence of these
other diagnoses in a population of children with
ADHD is somewhat
unexpected given the substantially higher rates
of such conditions
that are generally reported, and suggests that
the severity of the
symptoms of children in this sample may have
been on the mild
side.
It is instructive that nearly 20% of the original
sample of children with
ADHD were excluded because they were determined
to have
marked symptoms of sleep disordered breathing.
These children
were excluded because of the concern that this
sleep difficulty
could possibly explain the ADHD symptoms that
they had been
displaying, and the authors wanted to examine
reports of sleep
problems in children with ADHD for whom this
potential confound
had been eliminated. The fact that such
a substantial proportion
of ADHD subjected were found to have these strong
symptoms
of disturbed sleep underscores the importance
of attending to
such issues in a child's diagnostic evaluation.)
The design and procedures used in this study were
quite simple.
Parents of ADHD and control children completed
the Children's
Sleep Habits Questionnaire (CSHQ), a measure
that surveys
parents about a wide variety of children's sleep
behaviors and
problems and which has been validated in prior
studies. In
addition, a corresponding self-report sleep measure
was developed
to assess many of these same issues from the
child's perspective.
RESULTS
PARENT REPORT
The CSHQ contains 8 different subscales including:
bedtime
resistance, sleep-onset delay, sleep duration,
sleep anxiety,
night wakings, parasomnias (e.g. wetting the
bed, sleep walking,
nightmares), sleep-disordered breathing, and
daytime sleepiness.
Parents of children with ADHD reported more problems
than
parents of control children in every area except
for sleep
disordered breathing. (The absence of group
differences on this
scale is to be expected given that children with
ADHD who had
clear sleep disordered breathing difficulties
had already been
screened out.)
CHILD REPORT
The self-report measure for children was completed
by 36
children with ADHD who were at least 7 years
of age and
by 24 control children. Children with ADHD
also reported
themselves to have more sleep-related difficulties
than other
children, and the areas of difficulty they reported
are quite
interesting.
First, and not surprisingly, children with ADHD
reported
more fighting with parents around the issue of
bedtime. This
may be related to the more-frequent struggles
that children
with ADHD and their parents are likely to engage
in about a
variety of issues, and may not necessarily be
specific to
bedtime. In any event, it does highlight
that this is perceived
as an area of difficulty by many children with
ADHD, and
suggests that this may need to be a particular
focus of treatment
in many families.
Somewhat surprisingly - at least to me - the other
sleep-
related difficulties that children with ADHD
reported
centered around fears/anxieties associated with
bed time and
going to sleep. Children in the ADHD group
were more likely
to report that they needed a parent in the room
with them to
fall asleep, that they were afraid of the dark,
and that they
were bothered by nightmares. Thus, it appears
that children
with ADHD may be more likely than others to view
the
period around sleep onset as one "...that frequently
engenders
anxiety and is often difficult and unpleasant".
In fact, these
results leads one to wonder whether for some
children with
ADHD, the struggles that occur around going to
bed may
partially reflect their fear and anxiety about
sleeping alone.
SUMMARY AND IMPLICATIONS
Although the authors of this study are careful
to note that their
relatively small sample size requires that the
results obtained
be viewed with caution, the finding that sleep-related
fears and
worries may be more common in children with ADHD
is an
important one. What the reason for this
may be is unclear, but
it does suggest an avenue to explore when a child
with ADHD
is consistently struggling with parents around
bedtime or is
having problem getting sufficient sleep.
Another important issue highlighted by this study
is the importance
of screening all children who have symptoms suggesting
ADHD for sleep problems. As noted above,
this is because in
some causes, serious sleep difficulties (i.e.
sleep disordered
breathing problems such as obstructive sleep
apnea) may play
an important causative role in those symptoms,
while in other
cases they may certainly exacerbate the severity
of a child's
symptoms. Treatment strategies for children
with ADHD do
not routinely focus on sleep difficulties, and
treatment with
stimulant medication can actually produce sleep
problems as
a side effect in some children. Carefully
attending to a child's sleep,
and making sure that appropriate interventions
are in place to address
problems that may be apparent, can thus be an
important component
in the overall treatment plan for many children
with ADHD.
