Self-Efficacy Mediates the Association Between Physical Function and Perceived Quality of Life in Individuals with Mild Cognitive Impairment

"Non-Pharmacological Interventions that Improve Quality of Life in People with Mild Cognitive Impairment"

“…QOL was positively associated with self-efficacy, extraversion personality trait, and agreeableness personality trait, daily life functions, social net, work size, spatial cognition capabilities, and negatively associated with memory complaints, depressive symptoms, and neuroticism personality traits. A survey study showed self-efficacy as a mediator between physical function and perceived QOL in individuals with MCI [28]. However, another correlational study found that anxiety and depression partially mediated the effect of self-efficacy on QOL in people with MCI or dementia, with depression showing a medium mediation effect (b = 0.32, 95% CI = [0.23, 0.47]) [29].…”

Psychometric properties of the self‐efficacy for managing mild cognitive impairment scale

“…For example, a person may have significant physical limitations that keep them from walking independently, yet their sense of self‐efficacy to achieve their daily chores independently is high due to adaptive strategies or devices they know how to use to compensate. In our own research, evidence supported higher self‐efficacy attenuated the effect of physical decline on QoL 14 . As part of our efforts to study the impact of MCI behavioral interventions, 12,13,20,21 we adapted a self‐efficacy measure for managing chronic illness 22 to be specific to pwMCI.…”

While MCI-related changes do not significantly impede the person's ability to function independently, pwMCI can experience changes to their daily functioning (eg, managing finances, keeping track of appointments), as well as psychological changes and changes in QoL.…”

“…In aging research, self-efficacy, particularly memory self-efficacy (memory-SE), which is defined as a person's evaluation of his/her ability to complete a given memory task with confidence, 9 are variables of interest in examining factors that may maintain cognitive, functional, and psychosocial integrity in aging. Iteratively, it may impact and be impacted by cognitive training, [10][11][12][13] physical exercise, 14 depression, 15 and QoL. 14 Studies with cognitively impaired older adults show that improving self-efficacy might reduce the impact depressive symptoms has on cognition, supporting self-efficacy as a possible target for interventions.…”
