The purpose of the present study was to translate the Trinity Amputation
and Prosthetics Experience Scale (TAPES) into Persian and to investigate its
psychometric properties. METHOD: A sample of 182 Persian-speaker individuals with
lower limb amputation completed the TAPES questionnaire, of whom 103 individuals
completed the Short Form 36 Health survey as well. The TAPES was re-administered
to 41 participants in the retest session, with an interval of 5-7 days between
the two sessions. Internal consistency, test-retest reproducibility,
dimensionality, item internal consistency and discriminant validity and construct
validity were assessed. RESULTS: Cronbach's alpha's were greater than the cut-off
point of 0.70 for all subscales with the exception of social adjustment subscale.
Minimum intraclass correlation coefficient of 0.70 was exceeded by all subscales
with the exception of social activity subscale. Principle component analysis
performed on each section of the TAPES revealed loading of all items on their
corresponding factors. The exceptions were item 4 of social adjustment subscale
and the single item of weight subscale. Most items were stronger measures of
their hypothesised subscale than the other subscales. In terms of construct
validity, 75% of a priori hypotheses were confirmed. CONCLUSIONS: The Persian
version of TAPES seems to be a reliable and valid measure of psychological
adaptation to artificial limb.
