ObjectiveThis quasi-experimental study aimed to describe the outcome of a social skills intervention for adolescents with depression followed up at an outpatient Child and Adolescent Psychiatry Unit. Twenty adolescents with depression attending a tertiary care facility in Colombo, Sri Lanka were recruited, who participated in two social skills training programmes (6 months apart), in addition to pharmacological treatment. Outcome of the programme was measured by a self-administered questionnaire that assessed perceived changes in social skills, before and after the intervention. Wilcoxon Signed Rank test was used to determine the statistical significance of improvement in social skills.ResultsThe sample consisted of 80% (n = 16) female adolescents. Median scores (inter-quartile range) for social skills before and after the first social skills programme were 31.5 (21.0–36.0) and 33.0 (28.25–40.25) respectively, indicating a significant improvement in social skills following intervention (p = 0.011, r = 0.57). A similar improvement was observed after the second programme (n = 10), reporting higher median scores for social skills after intervention (29.5 vs. 37.5, p = 0.005, r = 0.89). A significant improvement was also observed in perceived ability to cope with depressive thoughts after intervention (p = 0.032), indicating that social skills training can be a useful adjunct to pharmacological interventions, in the management of depression in adolescents.
