Abstract

OBJECTIVE:

This study used a parent-completed, DSM-IV-referenced rating scale to examine prevalence rates of attention-deficit/hyperactivity disorder (ADHD) behaviors and differences between subtypes in 10- to 12-year-old Ukrainian children.

METHOD:

During 1997, a total of 600 parents and children residing in Kyiv, Ukraine, and their teachers participated in extensive clinical assessments using standard Western measures.

RESULTS:

The screening prevalence rate of ADHD behaviors was 19.8%: 7.2% for inattentive (I), 8.5% for hyperactive-impulsive (HI), and 4.2% for combined (C). Post hoc comparisons indicated a number of significant (p < .05) group differences. Mothers of children with ADHD symptoms reported higher rates of disruptive behavior, negative mother-child interactions, and physical punishment than the non-ADHD group. Teachers rated children with ADHD as more hyperactive and inattentive, but only the HI subtype was rated more oppositional than non-ADHD students. The I subtype was less academically proficient and socially adept (but less likely to have behavior problems). The C subtype was the most behaviorally disruptive (mother ratings), and their fathers were more likely to be aggressive and abuse alcohol. The HI subtype also had problems with disruptive behavior but were less socially impaired.

CONCLUSIONS:

Although symptom prevalence rates are higher in Ukraine than the United States, this study provides additional evidence supporting DSM-IV ADHD subtypes as distinct clinical entities.
