Factors associated with post-traumatic stress disorder (PTSD) following natural disaster among Indonesian elderly

摘要: Purpose The purpose of this paper is to analyze factors associated with post-traumatic stress disorder (PTSD) among elderly who live in a post-earthquake area. Design/methodology/approach This was a cross-sectional study involving 152 elder people who survived the disaster and were selected conveniently. The study was conducted in two worst-affected districts of Lombok Utara regency. PTSD was diagnosed using a modified version of the Clinician-Administered PTSD Scale version 5 (CAPS-5). The demographic data were assessed using a self-developed questionnaire consisting of 13 items. All data were analyzed by descriptive analysis, χ2 test and binary logistic regression with p<0.05. Findings Out of the 152 elder people, 91 (59.9 percent) suffered PTSD. Intrusion symptoms were the most common symptoms experienced by the respondents (94.1 percent). The factors associated with the PTSD in the elderly after the earthquake were having chronic illnesses (OR=2.490; 95% CI=1.151–5.385), public health center utilization (OR=2.200; 95% CI=1.068–4.535) and occupational status before the disaster (OR=2.726; 95% CI=1.296–5.730). These findings highlight that individual factors and access to health care services remain an important aspect of stress identification among the elderly following the disaster event. Social implications Elder people constitute a vulnerable group that is often forgotten and neglected during post-disaster recovery, though they have potentially higher psychosocial distress than younger age groups. This study was conducted to raise awareness about mental health problems suffered by the elderly. Originality/value This is the first study to apply CAPS-5 to assess PTSD among Indonesian elderly people following a natural disaster. This paper also provides insights that can be used by governments and other relevant parties to address PTSD problems suffered by many elderly people in a post-disaster area.
