Abstract:
Two different versions of the Prosthesis Evaluation Questionnaire (PEQ) are available. This study aimed to assess the measurement properties of the original 13-item Mobility Section of the Finnish version of the PEQ on a visual analogue scale (PEQ-VAS, 0–100 points) and its modified 12-item version with five response categories (PEQ-MS12/5, 0–60 points). Methods Patients having undergone major lower-limb amputation completed the PEQ, the PEQ-MS12/5, the Locomotor Capabilities Index–5, the Houghton Scale, and the 15D instrument, and answered general health and pain questions on a VAS. Participants who completed the instruments twice in a 2-week interval (n = 117) were included. Results Mean (SD) scores of the PEQ-VAS and the PEQ-MS12/5 were 58 (25) and 31 (13) with coefficients of variation of 0.42 and 0.43, respectively. Reproducibility was consistent between the measures. Although Spearman's correlation coefficient was high ( r = 0.83) and Kendall's coefficient of concordance was excellent (0.91), differences were noted in score distribution and patient rank correlation. There were similarities and differences in correlations with the other patient-reported instruments. Conclusions The original PEQ-VAS Mobility Section and the modified PEQ-MS12/5 have moderate measurement differences; the results are thus not directly comparable. Both measures provide reliable and valid scores, but the modified version is easier to complete and analyze in clinical work.
