“…Whether the WSPT program changed the depressed students' estimations or if it worked in a way to encourage CoM students to choose friends who do not smoke is left to be determined by future studies. Given the support in the literature, which suggests that depressed adolescents have a difficult time making friends and are often at the periphery of the social group, we are confident that the WSPT program changed cognitions rather than being able to affect change in friendships within a year (Aseltine, Gore, & Colten, 1994;Bosacki, Dane, & Marini, 2007;Henrich, Blatt, Kuperminc, Zohar, & Leadbeater, 2001;Oldehinkel, Rosmalen, Veenstra, Dijkstra, & Ormel, 2007;Pedersen, Vitaro, Barker, & Borge, 2007). Furthermore, both interpersonal and cognitive theories of depression suggest that difficulty with peer interactions, whether they are accurate with their perceptions or if they are biased in their perceptions, would agree that changing friendship groups would be unlikely (Joiner & Coyne, 1999;Lakdawalla et al, 2007;Marcus & Nardone, 1992).…”
