Background: Post-traumatic stress disorder (PTSD) can manifest in individuals following a traumatic event. There is a paucity of studies focusing on PTSD symptoms in ovarian cancer (OC) patients. This study aimed to investigate the association of social support, mental adjustment and PTSD symptoms in Chinese OC patients with a view to exploring whether mental adjustment could mediate the relationship.
Methods: A cross-sectional study was conducted from January 2015 to December 2016. A total of 171 OC subjects were recruited and the effective response rate was 81.3%. The PTSD Checklist-Civilian Version (PCL-C), Mini-Mental Adjustment to Cancer scale (Mini-MAC) and Duke-UNC Functional Social Support Questionnaire were disseminated to the patients. The Chinese Mini-MAC was used in this study focusing on three components, namely negative emotion, positive attitude, and cognitive avoidance. Hierarchical linear regression analyses were employed to investigate the association of social support and PTSD symptoms, and the role of mental adjustment in their mediation.
Results: The prevalence of PTSD symptoms was 17.3% in OC patients. PTSD symptoms were negatively related with both social support and positive attitude, and positively associated with negative emotion and cognitive avoidance. Social support was negatively associated with negative emotion and cognitive avoidance, and positively related with positive attitude. In addition, negative emotion and positive attitude mediated the association between social support and PTSD symptoms.
Conclusion: PTSD symptoms in OC patients should be paid attention to. Social support and mental adjustment were positive resources associated with PTSD symptoms. Moreover, mental adjustment could mediate the relation between social support and PTSD symptoms in OC patients. Therefore, intervention management that focusing on improving perceived social support as well as strengthening mental adjustment, especially negative emotion and positive attitude, may be useful for reducing PTSD symptoms in this context.
