Abstract
This study examined the relationships of adult attachment, mental toughness (MT), and psychological well-being of international students. We hypothesized that attachment anxiety and avoidance would predict psychological well-being outcome variables and that MT would mediate the attachment-wellbeing links. The participants were 217 international students from a large public college in the United States. Structure Equation Modeling analyses were used to examine the proposed mediation effects. Result showed that MT functioned as a mediator for the paths between attachment anxiety and the two well-being latent variables of psychological distress and life satisfaction. On the other hand, attachment avoidance was found to have a more direct effect on adjustment difficulties without going through MT. Limitation and counseling implications are discussed.
