In this survey study of 430 undergraduates, elements of the social competencies and interpersonal processes model (B. Mallinckrodt, 2000) were tested. Two social competencies were hypothesized to mediate the direct effects of 2 independent variables, attachment anxiety and avoidance, on 2 outcomes, psychological distress and perceived social support. Social self-efficacy was expected to be a significant mediator only for attachment anxiety. Emotional awareness, construed as low levels of alexithymia, was expected to be a significant mediator only for attachment avoidance. A bootstrap method was used to estimate the significance of indirect effects. Structural equation analyses suggested that, instead of specialized significant parings of one mediator with one independent variable, both social self-efficacy and emotional awareness served as significant mediators for both attachment anxiety and attachment avoidance.
