Prevalence, Predictors, and the Role of Social Support in Posttraumatic Stress Disorder among Cancer Patients in Oman

Background Cancer, regardless of type, presents a formidable life challenge affecting patients' psychological well-being. Many perceive cancer diagnosis and treatment as traumatic. Objectives This study aimed to estimate posttraumatic stress disorder (PTSD) prevalence in Omani adult cancer patients, identify predictors, and probe its correlation with social support. Methods This cross-sectional study enrolled 343 adult cancer patients undergoing treatment from 3 hospitals in the Middle East country of Oman. Posttraumatic stress disorder was assessed via the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and perceived social support was measured using the Multidimensional Scale of Perceived Social Support. Results The prevalence of PTSD among Omani adult cancer patients was 27.4%. Enhanced social support correlated with lower PTSD risk (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.93-0.97; P <.001). Predictors included shorter time since diagnosis (OR, 0.98; 95% CI, 0.97-0.99; P =.017), no psychiatric referral (OR, 0.46; 95% CI, 0.23-0.96; P =.04), and insufficient social support (OR, 0.96; 95% CI, 0.94-0.98; P <.001). Conclusions Social support significantly mitigates PTSD risk. Routine assessment and psychiatric referrals, especially for recent diagnoses, can enhance patients' lives. Reevaluating the PTSD diagnostic cutoff score (33) merits consideration for improved clinical use. Implications for Practice Early PTSD assessment, particularly for low-social support new-diagnosed patients, is crucial for timely intervention. Psychiatric referrals can guide specialized treatments. Stressing social support's role can guide healthcare providers, including oncology nurses, in supporting patients effectively.
