Perceived social support, coping strategies, anxiety and depression among women with breast cancer: Evaluation of a mediation model.

Purpose: Depression and anxiety are now considered as common adverse reactions to cancer. Prior research has shown that social support and functional coping strategies alleviate depressive and anxious symptoms of cancer patients but the exact relationship between social support and coping strategies in amelioration of the symptoms is yet to be elaborated.

Methods: The current study examined the relationship between social support, coping strategies and depressive-anxious symptomatology and explored the possible role of coping strategies in mediating the relationship between social support, depression and anxiety in Iranian breast cancer patients (N = 221). Anxiety and depressive symptoms were measured using the Depression-Anxiety-Stress (DASS-21) scale, social support was measured using the Medical Outcome Survey, Social Support Scale (MOSS-SSS), and coping strategies were measured using the brief COPE.

Results: All of the social support subscales were negatively correlated with depression and anxiety. Most of the coping strategies were negatively correlated with depressive-anxious symptoms. When controlling for covariates, mediation analysis revealed that active coping, positive reframing and acceptance partially mediated the association of social support of different types with depression. Positive reframing also partially mediated the relationship of the total social support and positive social interactions with anxiety.

Conclusions: High levels of social support may relieve depressive and anxious symptoms of breast cancer patients through functional coping. The management of breast cancer patients should also focus on providing patients with social support and educating them on the practice of functional coping strategies.
