Discerning critical stressors and resources in the lives of cancer patients: A multivariate analysis of targets of intervention for enhancing cancer care and quality of life

Objective This study examined the relationship between a broad variety of stressors, resources, and outcomes to identify targets of intervention to enhance the quality of life of cancer patients and contribute to a comprehensive model of cancer care. Methods Five hundred and sixty persons with a diagnosis of cancer completed measures of stressors (past negative life events, current problems, current symptoms, comorbidities), resources (coping self-efficacy, social support, satisfaction with care) and outcomes (emotional and functional well-being). Results Multivariate canonical correlations between pairs of canonical variates (stressors-outcomes, R-c = 0.56; stressors-resources, R-c = 0.42, resources-outcomes R-c = 0.66) were significant (all ps < 0.0001), which confirmed the relationship between those components and supported proceeding to more granular levels of analysis. More refined analyses revealed that the most critical variables in relation to outcomes (i.e., emotional and functional well-being), were current problems and symptoms among the stressors and coping self-efficacy, social support and patient satisfaction among the resources. Conclusions This study provided an approach to the discernment of the most critical aspects of interventions that may improve supportive care and quality of life outcomes. Thus, efforts to address current problems (e.g., financial, home life, work), as well as effective management of symptoms (e.g., pain, fatigue, sleep), using the coordinated integration of medical care, support services and psycho-social interventions would provide the greatest impact on quality-of-life outcomes. Interventions that focus on problem solving and reinforce patient agency and activation may be most effective in sustaining quality of life outcomes into survivorship.

Automated summary

This study examined the relationship between stressors, resources, and outcomes in order to identify intervention targets for enhancing the quality of life for cancer patients. The results showed that current problems and symptoms were the most critical stressors, while coping self-efficacy, social support, and patient satisfaction were the most important resources. Therefore, addressing current problems, effectively managing symptoms, and integrating medical care, support services, and psycho-social interventions can have the greatest impact on quality of life outcomes.
