Development and Factor Structure of the Mueller Assessment of Transition (MAT): A Tool for Measuring Older Adults' Wellbeing during Transitions into Assisted Living Facilities

This paper details the development and factor structure of the Mueller Assessment of Transition (MAT), a novel assessment to measure older adults' wellbeing when transitioning into assisted living facilities (ALF). Older adult participants (n = 69) in nine ALFs in the United States completed the MAT. Exploratory factor analysis identified a 2-factor, 12-item solution of influences on older adults' wellbeing. Further results found significant differences in older adults' wellbeing when transitioning into ALFs before and during the COVID-19 pandemic. Implications for healthcare practitioners and future research recommendations are discussed.
