The Multidimensional Task Ability Profile (MTAP) is a 111-item computer-administered questionnaire that is designed to assess perceived functional ability levels by utilizing pictures and captions that depict progressively demanding functional tasks. The evaluee rates their ability to perform each task on a 5-point scale and a rating of perceived capacity (RPC) is calculated.

PURPOSE

To evaluate the reliability and validity of the MTAP.

METHODS

In a sample of patients with musculoskeletal disorders (n=20; 39.8±7.3 yrs), the MTAP was administered on two occasions separated by 48–72 hours. The Spinal Function Sort (SFS), a validated pencil and paper instrument from which the MTAP was derived, was administered at the time of the second MTAP test. Test-retest reliability, internal consistency reliability, and concurrent validity were evaluated by calculating intraclass correlation coefficients that compared RPC scores between 1) the MTAP tests, 2) two subsets of items within the MTAP test, and 3) the MTAP and SFS, respectively. In another sample of patients (n=14; 41.3±9.5 yrs), the MTAP and the EPIC Lift Capacity Test (ELC), a standardized physical performance test, were administered. Predictive validity was assessed by calculating a Pearson product-moment correlation coefficient that compared the MTAP RPC score with the average weight of six lifts from the ELC.

RESULTS

Correlation coefficients for test-retest reliability, internal consistency reliability, concurrent validity, and predictive validity were r = 0.96, r = 0.98, r = 0.92; and r = 0.80, respectively, p < 0.05.

CONCLUSION

This preliminary study suggests that the MTAP provides a reliable and valid assessment of perceived functional ability, and can be used to predict actual functional ability levels.
