Abstract

Objective: The Yale Children's Global Stress Index (YCGSI) is a new clinical rating instrument designed to provide objective global clinician ratings of psychosocial stress in studies of children and adolescents. This study was designed to evaluate the psychometric properties of the YCGSI. Method: Independent ratings of clinical severity and psychosocial stress were obtained at two time points separated by 4 months from 33 subjects with Tourette's syndrome (TS) and/or early-onset obsessive-compulsive disorder (OCD), aged 7 to 17 years, and 25 age-matched control subjects. Parents and children were interviewed separately. Multiple measures of stress were obtained including the YCGSI and the Daily Life Stressors Scale (DLSS). Results: Data support the interrater reliability and convergent and divergent validity of the YCGSI. At both time points, children and adolescents with TS and OCD had, on average, experienced significantly more psychosocial stress than did the controls. Cross-sectional ratings of tic and obsessive-compulsive symptom severity did not correlate with the YCGSI, but did correlate with self-report ratings of stress on the DLSS. In contrast, ratings on the YCGSI were associated with clinician ratings of depression. Conclusions: The YCGSI has acceptable psychometric properties. Children and adolescents with TS and OCD appear to be at increased risk of experiencing higher levels of psychosocial stress and adversities compared with their peers in the community. Future studies need to examine the possible differential contributions of distinctive forms of stress on the intramorbid course of these disorders.
