The goal of this study was to evaluate family functioning in two groups of adolescents: adolescents with major depressive disorder (cases) and adolescents with no psychiatric disorders (controls). A total of 18 adolescents (13-18 years) and their first-degree relatives (N = 70) were evaluated. Cases and controls were matched for the adolescent's age, gender, level of education, number and age of siblings, parental marital status, and economic condition. A family therapist conducted the Structured Family Interview with each family to evaluate nine family functioning dimensions (communication, rules, roles, leadership, conflict, aggressiveness, affect, individuation, and integration). The interview transcripts were independently rated by two different family therapists blinded to case-control status, i.e., without knowing whether they were evaluating cases or controls. The raters scored all interview items using a standardized coding system (overall agreement = 83.5%), and when compared to the controls, the cases showed lower mean scores in seven dimensions, particularly affect (p = 0.0078). There was no difference between cases and controls regarding the dimensions rules and leadership. Difficulty in expressing affect in parent-child relationship was the main disturbance in the families of depressive adolescents evaluated.
