    • Abstract
      This study investigates the psychometric properties of the Meaningful Activity Participation Assessment-Meaning (MAPA-M) scale using the Rasch measurement model. For the psychometric properties of MAPA-M, principal component analysis, Rasch analysis, and differential item functioning analysis were conducted. Participants in this study were 480 older adults from the USC Well Elderly 2 study, recruited from 21 locations in the Los Angeles metropolitan area. There were eight items with DIF, but they were accepted because they assumed unidimensionality and showed good person invariance. The 25 items assuming unidimensionality of MAPA-M had val ues between 0.6 and 1.4 in infitandOutfit MnSq, and all ZSTD values were less than 2.0. The 25 items demonstrated a conceptual item-difficulty hierarchy. The person strata value was 2.68, which is equivalent to a reliability index value of .76. The findings indicate that the revised scale can accurately and reliably measure meaningful activities by older adults..
