A systematic review on social constraints in the context of cancer

This review aims to identify, summarise and critically evaluate studies that examined moderators or mediators of the relationship between social constraints and cancer adjustment. A database search was conducted to identify eligible studies published between inception and November 2019. A narrative synthesis of the included studies was conducted. We identified 18 papers, comprising 6933 participants (Mage = 55.70) with different types of cancer (mainly breast cancer). All of the studies used the Social Constraints Scale. Our synthesis shows that the association between social constraints and cancer adjustment is likely to be moderated or mediated by different cognitive (e.g. avoidant coping, intrusive thoughts) and emotional (e.g. emotionality, negative affect) variables. The importance of the moderators and mediators found in this study should be further examined by employing more sophisticated data analytic strategies to assess mediation and by collecting longitudinal data in order to better disentangle the complex associations among variables. However, some important variables were identified as potential targets of interventions for patients facing cancer.
