Et. Gortner et al., COGNITIVE-BEHAVIORAL TREATMENT FOR DEPRESSION - RELAPSE PREVENTION, Journal of consulting and clinical psychology, 66(2), 1998, pp. 377-384
This study presents a-year follow-up data of a comparison between comp
lete cognitive-behavioral therapy for depression (CT) and its 2 major
components: behavioral activation and behavioral activation with autom
atic thought modification. Data are reported on 137 participants who w
ere randomly assigned to 1 of these 3 treatments for up to 20 sessions
with experienced cognitive-behavioral therapists. Long-term effects o
f the therapy were evaluated through relapse rates, number of asymptom
atic or minimally symptomatic weeks, and survival times at 6-, 12-, 18
-, and 24-month follow-ups. CT was no more effective than its componen
ts in preventing relapse. Both clinical and theoretical implications o
f these findings are discussed.
