Perceived Health, Psychological Distress, and Subjective Well-Being among Older Adults with Parkinson’s Disease: A Cross-Lagged Analysis
2021

A growing aging population leads to a gradual increase in the number of patients with Parkinson&rsquo:s disease (PD). This study examines how perceived health, psychological distress, and subjective well-being evolve in older adults with PD. A cross-lagged study design was employed using data from Waves 4 and 6 of the Survey of Health, Aging and Retirement in Europe (SHARE). In total, 421 older adults diagnosed with PD at baseline (46% women: mean age 74.98&thinsp: ±: &thinsp:9.05 years) were included in the study and were followed up after a four-year lag. Auto-regressive and cross-lagged associations between the measured variables were examined in reciprocal models. Individual differences in perceived health, psychological distress, and subjective well-being were relatively stable over the 4-year lag. A final reciprocal model with significant cross-lagged effects explained the underlying structure of the sample data well: &chi:2 (49) = 101.876, p <: 0.001, CFI =&thinsp: 0.953, NFI = 0.935, RMSEA =&thinsp: 0.050, and AIC = 241.876. Increased difficulties in fulfilling instrumental activities and a lowered level of subjective well-being were particularly noticeable in older adults with PD during the four-year follow-up. Additional attention should be paid to helping older patients with PD cope better with their functional limitations and improve their sense of well-being.
