Abstract
BackgroundExternal housing-related control beliefs (HCB) and general self-efficacy (GSE) influence different health outcomes in the general ageing population, but there is no information of their role in people ageing with Parkinson’s disease (PD). This study aimed to longitudinally assess the role of external HCB and GSE on the association between housing accessibility and activities of daily living (ADL) among people ageing with PD.MethodsBaseline and 3-year follow-up data on 130 community-living participants from the Swedish project ‘Home and Health in People Ageing with PD’ were collected. Assessments addressed housing accessibility, external HCB, GSE, generic ADL and ADL specific to PD. The moderating effects of external HCB and GSE were assessed by including an interaction term in multivariable logistic regression.ResultsThere were statistically significant interactions between housing accessibility and GSE on ADL (p = 0.03), and housing accessibility and external HCB on PD specific ADL (p = 0.03). After stratifying the analyses by GSE, housing accessibility problems led to more dependence and difficulty in ADL in participants with low GSE (OR 1.14; 95% CI 1.02–1.28). After stratifying by external HCB, housing accessibility increased dependence and difficulty in PD specific ADL in participants with low external HCB (OR 1.35; 95% CI 1.03–1.76).DiscussionThe results suggest that housing accessibility predicts ADL in people with PD with GSE and external HCB playing a moderating role for generic ADL and ADL specific to PD, respectively. Further longitudinal studies should validate these findings and explore their potential application in PD-related care and rehabilitation.
Highlights
External housing-related control beliefs (HCB) and general self-efficacy (GSE) influence different health outcomes in the general ageing population, but there is no information of their role in people ageing with Parkinson’s disease (PD)
Functional limitations at T1 were moderately positively correlated with more dependence in both generic activities of daily living (ADL) and ADL specific to PD at T2, and had weak positive and negative correlations with external HCB and GSE at T1 (p-value ≤0.01), respectively (Table 2)
After stratifying the analyses by GSE, relative accessibility problem score (RAPS) was associated with generic ADL in participants with low GSE, while there was no effect in the high GSE group
Summary
External housing-related control beliefs (HCB) and general self-efficacy (GSE) influence different health outcomes in the general ageing population, but there is no information of their role in people ageing with Parkinson’s disease (PD). This study aimed to longitudinally assess the role of external HCB and GSE on the association between housing accessibility and activities of daily living (ADL) among people ageing with PD. General self-efficacy (GSE; i.e., beliefs in one’s abilities to achieve a goal) [12] was shown to play a role in health-related outcomes; it affected physical activity and self-management in people with PD [13, 14]. There is some evidence that assigning control over one’s housing plays a moderating role in the association between housing accessibility problems and ADL in adults 80–89 years old [18], but not in those 67–70 years old [19], which suggests age related differences. There are no longitudinal studies that measured the role of assigning control over one’s housing or GSE in the housing context
