Abstract
Objective
Although unmet support needs are associated with health-related quality of life (HRQOL) in cancer caregivers, little is known about the mechanism underlying the relationship between two variables. The self-efficacy (SE) theory and literature suggest that caregiving SE is important in the perception of and reaction to caregiving demands, which in turn affects HRQOL. The aim of this study was to examine whether caregiving SE mediates the relationship between unmet support needs and HRQOL in family caregivers of palliative cancer patients.
Methods
This secondary analysis used the data from 125 family caregivers of palliative cancer patients who were recruited from two public hospitals in Hong Kong. The caregivers completed a survey questionnaire that covered socio-demographic characteristics, unmet support needs, caregiving SE, and HRQOL. Parallel mediation analyses were conducted via SPSS PROCESS macro (Model 4) to test the hypothesized models.
Results
The direct effect of unmet support needs on mental HRQOL was significant (effect=-0.49, 95% CI=-0.06 to -0.92). For the indirect effect, only caregiving SE in the domain of “care for the care recipient” mediated the relationship between unmet support needs and mental HRQOL (effect=-0.32, 95% CI=-0.08 to -0.59).
Conclusion
The findings suggest that caregiving SE may function as a mechanism through which unmet support needs influence mental HRQOL in family caregivers of palliative cancer patients. Healthcare providers should consider developing supportive care interventions to improve caregivers’ HRQOL by incorporating effective strategies to enhance SE and reduce unmet needs for this population.
