The adolescent's level of functioning is assessed using the Child and Adolescent Functional Assessment Scale, the Birchwood Early Signs & Symptoms Scale for schizophrenia, and the DISA. Family Functioning is assessed by computing a Composite Family Functioning Index using weighted scores from the FACES II, Family Apgar, Family Empowerment, and Family Social Support scales. One parent is designated by the family to be the family respondent on the scales. The adolescents are referred to the study by mental health professionals. The intervention is administered in small multiple-family groups in 12 sessions over 7-1/2 months. Data are collected at 4 points in time: at baseline, after 6 intensive sessions, after 6 monthly reinforcement sessions, and 6 months post-intervention. ANCOVA is used to test the study hypotheses. Multivariate relationships are examined among the process variables of the intervention.
