Our findings suggest that scholars have implicitly and explicitly adopted a wide array of theoretical perspectives (e.g., stress and coping, social constructivism), with few studies engaging theories in substantive ways. The reviewed studies have demonstrated both positive and negative implications of social support for MCWs' well-being. However, these studies heavily focus on the social support MCWs receive, whereas the negative impacts of MCWs' unmet support needs remain under-investigated. Although empirical studies use diverse methodologies to study this topic, most quantitative studies approach social support from a stress and coping perspective. We advocate for researchers conducting quantitative studies to adopt a critical consciousness and work toward statistically modeling how the intersectionality of MCWs' identities and the multi-level nature of MCWs' power positions within their social networks may impact whether MCWs successfully obtain the support they need to thrive.
