Work-readiness self report lift capacity test short form

BACKGROUND: The Multidimensional Task Ability Profile (MTAP) is a measure of self reported physical work capacity developed for injured workers with musculoskeletal disorders (MSDs) to determine readiness to return to work. OBJECTIVE: This study compared the concurrent validity of a new short form MTAP (MTAP-SF) comprised of 16 lifting and/or carrying items with the MTAP 55-item version. The hypothesis addressed is whether the validity of a version that imposes less respondent burden (MTAP-SF) would be comparable to the more burdensome instrument (MTAP-55). METHODS: MTAP scores were compared with demonstrated lift capacity in 1,252 healthy adults. Parallel regression analyses were conducted to examine the explanatory power of both MTAP versions. RESULTS: Age, gender, body mass and MTAP-SF explained 55% of the variance (p
