Summary:Abstract Introduction Cognitive behavioral therapy for insomnia (CBT-I) has been shown to reduce depressive symptomatology among patients with co-occurring insomnia and depression. Brief forms of CBT-I have been tested in various settings including primary care. As delivery formats of CBT-I broaden, it is important to enhance our understanding of what doses and what components of CBT-I, provide the optimal balance of treatment efficacy and brevity. In the present study, we examine session-by-session effects of CBT-I on insomnia and depression. Methods Fifty-four Veterans with insomnia and co-occurring depression or posttraumatic stress disorder were randomized to either four sessions of CBT-I or treatment as usual in a published parent study. We report here on the effects among those who received CBT-I (n =22). At each session participants provided a completed sleep diary and completed the Insomnia Severity Index (ISI) and Patient Health Questionnaire-9 for depression (PHQ-9). Results At baseline, participants endorsed a moderate level of both insomnia (ISI score = 18.5 [SD=4.2]) and depression (PHQ-9 score = 15.6 [SD=5.2]). A mean decrease of 4.0 points in ISI total score was observed between sessions 1 and 2 [t(21)=-3.88, p
