Work-readiness self report lift capacity test short form

Area of Science:

• Occupational health
• Rehabilitation science
• Psychometrics

Background:

• The Multidimensional Task Ability Profile (MTAP) is a self-report measure for assessing physical work capacity.
• It is designed for injured workers with musculoskeletal disorders (MSDs) to evaluate return-to-work readiness.

Purpose of the Study:

• To compare the concurrent validity of a new 16-item MTAP short form (MTAP-SF) against the original 55-item MTAP.
• To determine if the MTAP-SF offers comparable validity with reduced respondent burden.

Main Methods:

• Concurrent validity was assessed by comparing MTAP scores with demonstrated lift capacity in 1,252 healthy adults.
• Parallel regression analyses were used to evaluate the explanatory power of both MTAP versions.

Main Results:

• The MTAP-SF, along with age, gender, and body mass, explained 55% of the variance in demonstrated lift capacity (p < 0.001).
• This explanatory power was equivalent to that of the full MTAP-55 version.

Conclusions:

• Self-reported physical work capacity significantly predicts lifting performance.
• The MTAP-SF effectively reduces respondent burden while preserving measurement validity.
• It can aid in managing MSDs by clarifying the psychophysical aspects of rehabilitation planning for return to work.
