The technology of self-report measures has advanced rapidly over the past few years. Recently, this technology was used to develop a performance-integrated self-report measure for use with patients with musculoskeletal impairments that may lead to work disability. Psychometric studies of the new measure in patient populations have been successful. A validation study of the measure with adults in good general health is necessary.
The purpose of this study was to assess the concurrent validity of a new performance-integrated self-report measure, the multidimensional task ability profile (MTAP).
STUDY DESIGN/SETTING: A prospective validation study was conducted in which a self-report measure was administered online, and a physical performance test was administered at various clinics in North America.
One hundred ninety-six (34% male) adult volunteers in good general health participated in this study.
Self-report measure-MTAP. Physiologic measure-EPIC Lift Capacity test.
The MTAP was administered online within 1 week of formal testing of lift capacity using a standardized lift capacity test, the EPIC Lift Capacity test. MTAP scores were compared with performance on the EPIC Lift Capacity test. Stepwise regression analysis was used to identify the strength of the relationship between the two measures and the relative explanation of lift capacity variance by the MTAP score, along with gender and age.
The combination of MTAP score, gender, and age demonstrated a regression coefficient of R=0.82, which accounts for 67.3% of the variance in lift capacity.
The MTAP displayed good concurrent validity compared with actual physical performance as assessed by the EPIC Lift Capacity test. Modern performance-integrated self-report measures, such as the MTAP, have the potential to provide information about functional capacity that is sufficiently useful to confirm status and help guide treatment algorithms.
在过去的几年中，自我报告测量技术迅速发展。最近，该技术被用于开发一种针对可能导致工作残疾的肌肉骨骼损伤患者的综合表现自我报告测量工具。该新测量工具在患者群体中的心理测量研究已经成功。需要对健康成年人进行该测量工具的验证研究。
本研究旨在评估一种新的综合表现自我报告测量工具多维任务能力概况（MTAP）的同时效度。
研究设计/设置：进行了一项前瞻性验证研究，其中在线管理自我报告测量工具，并在北美的各个诊所进行物理性能测试。
本研究共纳入 196 名（34%为男性）健康状况良好的成年志愿者。
自我报告措施-MTAP。生理测量-EPIC 提升能力测试。
在使用标准化提升能力测试 EPIC 提升能力测试正式测试提升能力的 1 周内，在线管理 MTAP。将 MTAP 分数与 EPIC 提升能力测试的表现进行比较。逐步回归分析用于确定两种方法之间的关系强度以及 MTAP 分数、性别和年龄对提升能力方差的相对解释。
MTAP 分数、性别和年龄的组合显示回归系数 R=0.82，占提升能力方差的 67.3%。
与 EPIC 提升能力测试评估的实际身体表现相比，MTAP 显示出良好的同时效度。现代综合表现自我报告测量工具，如 MTAP，具有提供足够有用的功能能力信息的潜力，以确认状态并帮助指导治疗算法。
