Social Support Protects Against the Negative Psychological Impacts of Death Anxiety, and Depression on Posttraumatic Growth in Cancer Patients.

People living with cancer may experience death anxiety and depression which may impact their experience of posttraumatic growth (PTG). Social support is a psychosocial resource that protects against negative psychological outcome. Although a direct association among these variables exist, little is known about their interactive effect. Dwelling on the buffering hypothesis, this study examined the role of social support in the association of death anxiety and PTG. We further investigated whether depression-PTG relationship would be moderated by social support. Cancer patients (N = 412) were randomly selected from two healthcare institutions. Participants completed relevant self report measures, and data were analyzed using Hayes PROCESS macro for SPSS. Results showed that social support buffered the effect of death anxiety on PTG. The relationship between depression and PTG was also moderated by social support. Interventions to facilitate PTG should target social support network of patients due to its potentials in buffering the effect of death-related anxiety and depression on patients' PTG.
