Rates and correlates of psychological distress and PTSD among persons with physical disabilities in Cambodia

Abstract

Abstract Background Compared to the general population, persons with disabilities are at increased risk of poor mental health. The aim of this study was to determine the rates and correlates of psychological distress and post-traumatic stress disorder (PTSD) among persons with physical disabilities in Cambodia. Methods From July to December 2021 data were collected as part of a mental health screening programme for persons with physical disabilities who access prosthetic and orthotic services. Psychological distress was measured using the Kessler-10 (K-10) and PTSD using the PC-PTSD-5. Bivariate and multiple linear regression analyses were conducted to identify factors associated with levels of psychological distress and PTSD among this population. Results Our study found a high prevalence of psychological distress and PTSD in this patient cohort. Of the 213 participants, 31.5% were likely to be experiencing mild to moderate psychological distress indicative of a mental health disorder, with 13.6% likely to have a severe mental health disorder. Sixty-five percent of patients reported experiencing PTSD symptoms, with forty-six percent meeting the criteria for probable PTSD. Psychological distress was associated with pathological worry, rumination, and facets of mindfulness. Rumination and pathological worry were found to be significant predictors of psychological distress. PTSD symptoms were associated with pathological worry but not facets of mindfulness or rumination. Facets of mindfulness and pathological worry were found to be significant predictors of PTSD. Conclusion Integration of mental health services within the disability sector is required to address psychological distress and PTSD symptoms among people with physical disabilities in Cambodia. Health system interventions, such as screening, referral, and the training of health providers, need to be strengthened. Further studies focussing on the psychosocial determinants of mental health of persons with disabilities in Cambodia are required.
