Psychological and behavioural factors can significantly influence the well-being of older adults, especially their capacity to perform Activities of Daily Living (ADLs), which are crucial for independent living. However, a comprehensive model elucidating how these factors contribute to older adults' perception of their ability in such skills is still lacking. This study aims to confirm a theoretical model according to the evidence gathered from the literature.
A total of 473 older adults (mean age = 69; SD = 7; 33% males) participated in the study. Their health perception, fear of falling, general self-efficacy, depressive symptoms, physical activity level, sedentary behaviour, and perceived disability in ADLs were assessed. A theoretical model involving these variables was produced using Bayesian Structural Equation Modelling.
The results indicated successful convergence, with estimated posterior distributions proving insensitive to the prior distribution, and an overall excellent fit. Difficulties in activities of daily living did not exhibit associations with physical activity (B = -0.07, 95%CI [-0.17, 0.04]); however, an association was observed with sedentary behaviour (B = 0.03, 95%CI [0.01, 0.04]). In turn, sedentary behaviour was significantly predicted by depressive symptoms (B = 1.81, 95%CI [1.33, 2.29]), fear of falling (B = 0.50, 95%CI [0.10, 0.90]), and general self-efficacy (B = -2.31, 95%CI [-2.84, -1.77]). Health perception is directly associated with these three psychological variables.
The model confirms the significant role of psychological and behavioural factors in explaining older adults' perception of their capacity to perform daily activities. Addressing these aspects could enhance ADLs and impact their well-being.
