“…Overall, studies comparing the efficacy of assertiveness training to other evidence-based treatments have found that although assertiveness training is generally effective in increasing assertive behaviors and decreasing depressive symptoms, its efficacy is essentially equivalent to other forms of treatment for depression (Rehm, Fuchs, Roth, Kornblith, & Romano, 1979;Rude, 1986;Zeiss, Lewinsohn, & Muñoz, 1979). Two meta-analyses of past research comparing psychotherapy outcomes for depression in adults (Barth et al, 2013;Cuijpers et al, 2008) and a review of the social skills literature (Jackson, Moss, & Solinski, 1985) have come to largely the same conclusion, finding that social skills training, which primarily involved assertiveness training, was more effective than wait-list control and largely no different in effectiveness compared to other psychotherapeutic interventions, such as cognitive therapy or behavioral activation. An important issue that was indicated from these meta-analyses and the reviews that have been conducted on the efficacy of assertiveness training for depression is the paucity of empirical studies relative to other evidence-based treatments (Heimberg et al, 1977).…”
