This study examines the factors influencing friendship quality during emergent adulthood. Data were collected on a sample of 393 college students (age range 18–22, M = 20.01). Nine multi-item measures were used as indicators in this study. Seven scales were drawn from the Battery of Adolescent Measures (Benson & Faas, 2014). The other two were the pragmatic (social) language and the aloof scales, which provided sensitised assessment of interpersonal deficits (Hurley, Losh, Parlier, Reznick, & Piven, 2007). The article hypothesises that family warmth predicts friendship quality during emergent adulthood. It also hypothesises that this relationship is mediated by emergent adults’ self-perceptions and by their social competence. Structural equation models supported the first hypothesis and also showed that self-perceptions and social competence partially mediate the main relationship. We also examined each mediator separately for evidence of partial mediation, but the full model remained a significantly better fit to the data compared to both single mediator models.
