Crucially, impaired interpersonal competence associates with vulnerability to stress and negative life events (Cummings et al, 2013;Segrin, 2001), loneliness (DiTommaso, Brannen-McNulty, Ross, & Burgess, 2003), and, perhaps more importantly, psychopathology (Segrin, 1990(Segrin, , 1993Skodol et al, 2005). Indeed, it is fairly well known that poor interpersonal functioning is a key feature of virtually all personality disorders (Kim, Pilkonis, & Barkham, 1997;Muralidharan, Sheets, Madsen, Craighead, & Craighead, 2010;Skodol et al, 2005).…”
