Psychometric properties of Meaningful Activity Participation Assessment (MAPA) in chronic stroke survivors

Background Meaningful Activity Participation Assessment (MAPA) is an appropriate tool for assessing both objective and subjective aspects of participation. Objectives This study aimed to investigate the psychometric properties of MAPA in chronic stroke survivors. Methods Translation of MAPA was done according to the standard protocol of forward-backward translation. One hundred and seven chronic stroke survivors participated in this study. In addition to the MAPA, they were assessed by Satisfaction With Life Scale (SWLS), Center for Epidemiologic Studies of Depression Scale (CES-D), Life Satisfaction Index-Z (LSI-Z), Purpose in Life Test-Short Form (PIL-SF), and 36-Item Short-Form Survey (SF-36). To investigate the test-retest reliability, 37 participants were reassessed by MAPA after two weeks. Reliability, construct and known-groups validity were evaluated for MAPA. Results The results showed an acceptable internal consistency (Cronbach's alpha = 0.79) and good test-retest reliability (ICC = 0.92) of MAPA. A significant moderate to high correlation was found between the MAPA and PIL-SF, CES-D, LSI-Z, SWLS, and different subscales of SF-36 (r = 0.32-0.65). MAPA showed good ability to differentiate between young adults (age <= 65 years) and older adults (age> 65 years) with chronic stroke (P= .005) as well as between chronic stroke survivors with different levels of disability (P< .001). Conclusions The MAPA has appropriate reliability and validity in chronic stroke survivors and is suggested to be used in research and clinical settings.
