Depression and life satisfaction among people ageing with post-polio and spinal cord injury

Abstract

Purpose and background: Attention has recently begun to focus on the ageing of individuals with disability, not only as a longterm follow-up issue but as a unique developmental issue itself. The majority of individuals with an onset of disability before age 30 can now expect to live into their 60s, 70s and beyond. Most of the secondary medical conditions that foreshortened life expectancy have been controlled and improved rehabilitation techniques have evolved over the last 50 years. The average age of persons with post-polio in the United States is over 50 and the average age of persons with spinal cord injury is in the late 40s. New medical, functional and psychosocial problems have been discovered among persons ageing with these and other disabilities. Most of these problems lack sufficient scientific explanation, and therefore, clinical interventions. Quality of life (QOL) issues become involved as these changes occur. From a psychological perspective, QOL can be either positive, as reflected in high life satisfaction, or negative, as reflected in distress and depression. Methods: This study reports on life satisfaction and depression in 360 persons, 121 with post-polio, 177 with SCI and 62 nondisabled age-matched comparisons. The Geriatric Depression Scale and the Older Adult Health and Mood Questionnaire assess depressive symptomatology and a 10-item life satisfaction scale with four-point ratings on each item used. Results: Life satisfaction varied by the group, with the nondisabled group higher than one or both of the other two groups on all scales and the post-polio group higher than the SCI group on six scales. Satisfaction with health, finances, work and overall life were most different. 22% of the post-polio group, 41% of the SCI group and 15% of the non-disabled group had at least significant repressive symptomatology. Conclusion: The results for each group are discussed in terms of their relation to other coping variables that were assessed, particularly social support and coping methods.
