Health-Related Quality of Life and Suicidal Behaviors in Primary Care Patients: Conditional Indirect Effects via Interpersonal Needs and Depressive Symptoms
Suicide is a public health problem and complex relationships exist between intrapersonal suicide risk factors and interpersonal risk factors. Health-related quality of life (HRQL) may interact with difficulties with interpersonal relationships and psychopathology. We examined thwarted interpersonal needs and depressive symptoms as potential mediators on the association between HRQL and suicidal behaviors. It was hypothesized that thwarted interpersonal needs would mediate the association between HRQL and suicidal behavior, and that this mediating effect would be dependent on the moderating effect of depressive symptoms. It was hypothesized that thwarted interpersonal needs and then depressive symptoms would sequentially mediate the association between HRQL and suicidal behavior. The mediating roles of thwarted belongingness and perceived burdensomeness on the association between HRQL and suicidal behaviors were supported. Moderated-mediation results were not significant. Serial mediations analyses were partially supported. Our findings suggest the importance of considering both interand intrapersonal factors on suicidal behavior
