Abstract
The ADHD Checklist is composed of 14 items used to evaluate
the occurrence of ADHD symptoms in children. These items are listed
as the criteria for ADHD in the DSMIII-R and have been placed into
a checklist format (DuPaul, 1990). The same checklist can be used
for both parents and teachers (see separate detailed technical reports).
The 14 items evaluate a child's behavior and the likelihood of
the child having ADHD. Each item is scored on a response scale of
0 to 3, where 0=not at all, 1=just a little, 2=pretty much, and
3=very much.
There are three derived scores and two diagnostic categorizations
for this measure. All of these subscales are summary scores that
are based on factor analysis or theoretically derived. The first
scale measures Inattention. The second scale measures Impulsivity.
The next scale measures the Total of all the items. Those scores
in this category that exceed the 1.5 standard deviation mark above
the mean for age/sex are considered a clinically significant score.
A dichotomous score (0 = "not clinically significant"
and 1 = "clinically significant") is formed using a cutoff
of 33 for male respondents and 24 for female respondents, based
on the norms for age 8 provided by DuPaul.
The last scale measures the Number of Symptoms Present and includes
all of the items. Adding the number of items rated as 2 or higher
scores this scale. A score of 8 or more exceeds the DSMIII-R cutoff
for a diagnosis of ADHD. Respondents with a total score at or above
the clinical cutoff receive a "1" to indicate a diagnosis
of ADHD. A "0" indicates that the respondent was not diagnosed
with ADHD.
Analysts should note that three of the subscales showed a fairly
normal distribution for both the normative and control samples.
These subscales were Inattention, Impulsivity, and Total of all
the items. Both the normative and the control samples were positively
skewed for the Number of Symptoms Present.
The normative sample for Number of Symptoms Present showed a floor
effect with 91% of the responses to be between 0.0 and 3.0. The
control sample for Number of Symptoms Present showed a floor effect
with 76% of the responses to be between 0.0 and 3.0. The highest
possible score for this scale was 14.0.
