Adult Attachment, Social Self-Efficacy, Self-Disclosure, Loneliness, and Subsequent Depression for Freshman College Students: A Longitudinal Study.

This longitudinal study examined whether social self-efficacy and self-disclosure serve as mediators between attachment and feelings of loneliness and subsequent depression. Participants were 308 freshmen at a large midwestern university. Results indicated that social self-efficacy mediated the association between attachment anxiety and feelings of loneliness and subsequent depression, whereas selfdisclosure mediated the association between attachment avoidance and feelings of loneliness and subsequent depression. These relationships were found after controlling for the initial level of depression. A total of 55% of the variance in loneliness was explained by attachment anxiety, social self-efficacy, and self-disclosure, whereas 42% of the variance in subsequent depression was explained by the initial level of loneliness and depression. Implications of the findings for enhancing freshman adjustment are discussed.
