Participants are assessed with clinical interview, polysomnographic evaluation and screening with Insomnia Severity Index (ISI), Dysfunctional Beliefs About Sleep-scale (DBAS), HDRS, MINI and Sleep Diary pre and post treatment. Participants are randomly assigned to either treatment as usual or CBT-I. The latter receives individual as well as group therapy with CBT-I during 6 sessions. Post-treatment: The investigators will compare changes in sleep diary parameters, HamD17, ISI and DBAS. Data are analyzed by using Chi-square test, Wilcoxon-Mann-Whitney U-test and ANOVA. STATA is used for data-processing.
