This article describes the development and evaluation of the revised Ontario Child Health Study (OCHS) scales to measure conduct disorder, oppositional disorder, attention-deficit hyperactivity disorder, overanxious disorder, separation anxiety and depression based on DSM-III-R symptom criteria. Problem checklist assessments were obtained from parents and teachers of children aged 6-16 and youths aged 12-16 drawn from: (1) a general population sample (N = 1751); and (2) a mental health clinic sample (N = 1027) in the same industrialized, urban setting. Evaluation of the revised OCHS scales indicates that they possess adequate psychometric properties and provide an efficient means to obtain measurements of childhood psychiatric disorder, in general population studies, that correspond to DSM-III-R classification of disorder.

Objective: To obtain preliminary evidence of the feasibility and effectiveness of adjunctive family psychoeducation in adolescent major depressive disorder. Method: Participants were from outpatient clinics in Hamilton and London, Ontario.Over 24 months, 41 adolescents ages 13 through 18 years meeting major depressive disorder criteria were recruited (31 in Hamilton, 10 in London). Participants were randomized to usual treatment or usual treatment plus family psychoeducation. Outcome measures were readministered at 2 weeks, mid-treatment, posttreatment, and 3-month follow-up. Intent-to-treat analyses used x 2 and t tests and growth curve analysis. Standardized effects based on growth curve estimates were calculated for continuous outcomes.
