Prevalence and associated features of depression and psychological distress in polio survivors

This cross-sectional study examines the prevalence of psychological distress and depression among 116 polio survivors. It investigates demographic, medical, and coping differences between subjects with (n = 17) and without (n = 99) these symptoms. Subjects were administered the Brief Symptom Inventory (BSI), the Coping with Disability Inventory (CDI), and a questionnaire about their polio histories. The BSI provided measures of psychological distress and depression that defined the subgroups. The CDI assessed coping behaviors. BSI scores for the overall sample were within the normal range indicating no major distress, depression, nor elevated somatic complaints. Several significant differences were found between the two subgroups. On average, depressed/distressed subjects reported an increase in pain (p < .01) and further deterioration of their medical status since the time of their physical best subsequent to the onset of polio (p < .01). They consistently rated their health as poorer than did nondepressed/nondistressed subjects (p < .001). They also reported less satisfaction with life and their occupational status (p < .001) and displayed poorer coping behaviors combined (p < .001). Selected variables such as life satisfaction, pain, decrease in activity, and current living situation accounted for 51% of the variance when predicting distress and depression among this group of polio survivors.
