SDQ Dysregulation Profile and Its Relation to the Severity of Psychopathology and Psychosocial Functioning in a Sample of Children and Adolescents With ADHD.

Objective: A substantial number of children and adolescents with ADHD show severe affective and behavioral dysregulation. A dysregulation profile (DP) distinguishes those participants at a higher risk of comorbidity, dysfunction, and a poorer response to treatment. It was identified as high scoring in certain subscales of the Strengths and Difficulties Questionnaire (SDQ-DP). We developed a cross-sectional study to assess the clinical utility of the SDQ-DP in ADHD. Method: Two hundred fifty clinic-referred children and adolescents with ADHD were assessed. Univariate and linear regression analyses were performed to compare those participants with high levels of SDQ-DP with those with low levels, as well as to examine the association between the SDQ-DP and clinical variables. Results: In all, 28% of ADHD participants had high levels of SDQ-DP. These participants showed higher functional impairment and clinical severity. Conclusion: The use of the SDQ-DP will enable identification of those ADHD patients at greater risk. [ABSTRACT FROM AUTHOR]
