Research suggests attachment style may contribute to individual differences in resilience, but little is known about the mechanisms of this relationship. Self-care and self-efficacy may be promising pathways by which attachment influences resilience. The current study evaluated the contributions of attachment security, self-efficacy, and self-care to resilience among a sample of undergraduate students. We hypothesized that individuals with a more secure attachment style would experience greater resilience via increased self-efficacy and more frequent practicing of self-care. Participants reported attachment style, resilience, self-efficacy, and self-care. Results partially supported the hypotheses; self-efficacy and self-care partially mediated the relationship between attachment security and resilience. Therefore, to promote resilience, it may be preferable to focus efforts on these more malleable factors.
