A brief cognitive-behavioural group therapy programme for the treatment of depression in adolescent outpatients: a pilot study

BACKGROUND: The goal of this pilot study was to examine the feasibility and clinical outcomes of a brief (6-session) group therapy programme in adolescent outpatients with depression. The programme had previously been assessed in in-patients, with positive results. METHODS: A total of 15 outpatients aged 13 to 18 years took part in the programme between October 2010 and May 2011, in 3 separate groups of 4–6 participants each. The outcomes measured were feasibility of the programme, as assessed by attendance rate, user feedback, fidelity of implementation, and response to treatment, as assessed by pre- and post-intervention measurement of depressive symptoms, quality of life, and suicidal ideation. RESULTS: The programme demonstrated good feasibility, with a mean attendance rate of 5.33 out of 6 sessions, a mean rating by participants on overall satisfaction with the programme of 7.21 out of 10 (SD = 1.89), and a 93% concurrence between the contents of the sessions and the contents of the treatment manual. Compared to baseline scores, depressive symptoms at follow-up test were significantly reduced, as assessed by the Children’s Depression Rating Scale Revised (F(1, 12) = 11.76, p < .01) and the Beck Depression Inventory Revision (F(1, 32) = 11.19, p < .01); quality of life improved, as assessed by the Inventory of Quality of Life (F(1, 31) = 5.27, p < .05); and suicidal ideation was reduced. No significant changes were seen on the measures of the Parent Rating Scale for Depression and the Clinical Global Impression scale. CONCLUSIONS: Based on the results of this pilot study, it is feasible to further assess this brief outpatient treatment programme in a randomized controlled trial without further modifications.
