This research involved the development of a behavior rating scale designed
to measure ADHD and the investigation of the scale's psychometric propertie
s and factor structure. This scale, the ADHD Symptoms Rating Scale (ADHD-SR
S) was developed for the assessment of ADHD in the school-age (K-12) popula
tion. Participants were 1006 children and adolescents (in grades K-12) who
were rated by their parents and/or teachers. The results indicate that the
ADHD-SRS possesses strong internal consistency reliability and test-retest
reliability and moderate cross-informant reliability. The data also suggest
that the ADHD-SRS has strong content validity. Convergent validity of this
instrument was also high, as demonstrated by correlations with three previ
ously validated behavior rating scales. Significant age and gender differen
ces in ADHD symptoms were found with both the parent and teacher respondent
populations. Finally, the factor analysis of the ADHD-SRS suggested a two
factor oblique rotation as the best fit for both the parent and the teacher
data. After a visual inspection of the items which loaded on each factor F
actor I was named Hyperactive-Impulsive and Factor 2 was named Inattention.
These two factors, along with the items which loaded on each factor appear
to be remarkably similar to the two categories listed in the DSM-IV for AD
HD. Directions for future research, as well as clinical implications and li
mitations of the research are discussed.
