Abstract

Objectives:

To investigate the factorial composition of the Trinity Amputation and Prosthesis Experience Scales (TAPES), a multidimensional assessment of adaptation to amputation and prosthesis, for use with individuals with acquired upper limb amputations.

Design:

Cross-sectional survey of members of the British Limbless Ex-Service Men’s Association.

Results:

A total of 101 individuals (men, 100; mean age, 73.8 yrs, SD 11.94) with acquired upper limb amputations (98 traumatic cases) completed the TAPES. Principal components analyses with varimax rotation revealed four psychosocial subscales (general adjustment, social adjustment, optimal adjustment, and adjustment to limitation), four activity-restriction subscales (restriction of lifestyle, social restriction, occupational restriction, and restriction of mobility), and a single prosthesis-satisfaction subscale. Each of these subscales had high internal reliability.

Conclusions:

The TAPES structure can be meaningfully represented in terms of nine internally consistent subscales. Additional research needs to be done on the TAPES for use with individuals with upper limb amputations. In particular studies of the scales, predictive validity is warranted.
