Reliability and construct validity of the Turkish version of the Trinity Amputation and Prosthetic Experience Scales (TAPES) in lower limb amputees

Background: In Turkey there is no amputee-specific instrument to measure health-related quality of life in lower limb amputees. Objectives: To evaluate the validity and reliability of a Turkish version of the Trinity Amputation and Prosthesis Experience Scales (TAPES). Study design: Outcome study to determine test-retest reliability and construct validity of the adapted Turkish version of the TAPES. Methods: After translation/retranslation of the TAPES, the Turkish version of the TAPES was applied to 47 amputees. A quality of life evaluation (Nottingham Health Profile), a satisfaction evaluation (Satisfaction with Prosthesis), and a functional assessment tool (Amputee Mobility Predictor) were also performed and analysed. Results: On the basis of retesting, the Turkish version of the TAPES was observed to be reliable. The first domain of the Turkish version, which includes psychosocial adjustment, activity restriction and satisfaction with the prosthesis, was found to be valid. However, the validity of the second domain could not be analysed. Conclusions: The Turkish version of the multidimensional TAPES survey is valid and reliable in Turkish unilateral lower limb amputees and may be used in clinical situations to assess the needs of amputees. Clinical relevance The Turkish version of the TAPES quality-of-life measurement tool for amputees is a valid instrument for assessing the effectiveness of rehabilitation and clinical applications.
