A two-year longitudinal study of social support following amputation

Purpose: (1) To describe one aspect of social support, social integration, longitudinally for 2 years following lower limb amputation and (2) to explore the impact of social support on depression, pain interference, life satisfaction, mobility, and occupational functioning. Method: Eighty-nine adults recruited from consecutive admissions to an orthopaedic surgery service completed telephone interviews 1, 6, 12 and 24 months following amputation surgery. Dependent variables included the Social Integration (SI) sub-scale of the Craig Handicap Assessment and Reporting Technique (CHART) and the Multidimensional Scale of Perceived Social Support (MSPSS). Results: There was a high level of SI among most persons following lower limb amputations that was relatively unchanged in the 2 years following surgery. However, mean levels of SI were lower in this group compared to a sample without disabilities. MSPSS scores were highly variable, ranging from almost no support to the maximum amount of support. MSPSS was an important concurrent predictor of pain interference, life satisfaction, and mobility, controlling for demographic and amputation-related factors. Baseline MSPSS predicted mobility and occupational functioning 6 months post-amputation, controlling for demographic and amputation-related factors. Conclusions: Findings suggest that interventions aimed at improving the quality of social relationships after amputation may facilitate participation in activities.
