Ee. Nolan et al., ASSOCIATED PSYCHOPATHOLOGY IN CHILDREN WITH BOTH ADHD AND CHRONIC TICDISORDER, Journal of the American Academy of Child and Adolescent Psychiatry, 35(12), 1996, pp. 1622-1630
Objective: To examine the relation between severity of tic disorder an
d comorbid psychopathology in 47 prepubertal children with tic disorde
r who were referred for clinical evaluation of and treatment for atten
tion-deficit hyperactivity disorder (ADHD), oppositional behaviors, an
d aggressive behaviors. Method: Parents and teachers completed the Chi
ld Behavior Checklist (CBCL) and Teacher's Report Form (TRF) for each
child. Results: Seventy-five percent of the sample was in the clinical
range in at least two categories of psychopathology. When the childre
n were divided into two groups on the basis of tic severity, significa
ntly higher scores were obtained for children with more severe tics on
the narrow-band Depressed, Uncommunicative, Obsessive-Compulsive, and
Aggressive scales, and the broad-band internalizing scale oi the CBCL
. The severity groups did not differ on TRF scores. Children who were
more aggressive also received higher CBCL scores. Conclusions: The fin
dings from this study suggest that the severity of chronic ties is a c
linical indicator of complex psychopathology in children with ADHD who
are referred for psychiatric evaluation.
