Abstract
Background
Quality of life is a multidimensional concept that includes perceptions of one’s physical, psychological, social, and spiritual functioning, all of which are theorized to be interdependent. The focus of this study is social functioning, which itself is a multidimensional concept that includes social support and social constraint among other things. In cancer survivors, social support receives most of the research attention, but social constraint may have a stronger influence on quality of life.
Purpose
This systematic literature review evaluates which aspect of social functioning—social support or social constraint—has a stronger relationship with the psychological functioning of cancer survivors.
Methods
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed in the identification and review of 32 independent records. Multiple measures of social support and social constraint were used across studies, with most having adequate psychometric properties. Psychological outcomes were divided into (a) general distress, (b) cancer-specific distress, (c) general well-being, and (d) cancer-specific well-being.
Results
For general and cancer-specific distress, social constraint exhibited a larger association with distress than social support. Similarly, for general well-being, most studies reported a stronger association with social constraint than social support. For cancer-specific well-being, the opposite was true such that associations were stronger for social support than social constraint.
Conclusions
Results highlight the importance of considering social constraint when examining quality-of-life outcomes like psychological distress and well-being. Findings support social constraint as a target in interventions to reduce cancer survivors’ distress, while social support could be considered in attempts to promote cancer-specific well-being.
