N2 - Background:Most amputees live with their prostheses for a long time. Therefore, quality of life is an important outcome for lower limb amputees.Objective:To translate the Prosthesis Evaluation Questionnaire (PEQ) and evaluate psychometric properties.Study Design:Methodological research.Methods:Lower limb amputees responded to electronic versions of the PEQ and SF-36v2 at baseline (n=64), after two weeks (n=51), and after 12 weeks (n=50). Reliability was assessed using Cronbach’s alpha and intraclass correlation coefficient (ICC) analyses of the baseline and two weeks test-retest data. Estimates for standard error of measurement (SEM) were calculated based on reliability estimates. Construct validity was evaluated by testing using hypotheses testing.Results:Reliability estimates (ICC/Cronbach’s alpha) for the nine subscales were: Social Burden (0.85/0.76), Appearance (0.85/0.72), Residual Limb Health (0.80/0.69), Well-Being (0.78/0.90), Utility (0.76/0.89), Frustration (0.74/0.90), Perceived Response (0.62/0.80), Ambulation (0.61/0.94), Sounds (0.51/0.65). Construct validity was supported in three out of four subscales evaluated.Conclusions:The subscales Social Burden, Appearance, Well-Being, Utility and Frustration had consistent high reliability, supporting their use in assessing the prosthesis related quality of life in lower limb amputees. Results were mixed on three other scales (Residual Limb Health, Perceived Response, and Ambulation), while one scale, Sounds, had consistent low reliability.Clinical relevance:For the first time a patient reported disease specific quality of life measure for lower limb amputees is available in Danish. Health care providers can now identify patients with reduced quality of life and measure treatment and rehabilitation effects over time.
