Prediction of Life Satisfaction in People with Parkinson’s Disease

Table 2

Model 1: multivariable logistic regression analyses with life satisfaction (3-year follow-up) as the dependent variable (personal factor and motor-related aspects as independent variables).

Independent variables	Unadjusted for life satisfaction at baseline, n = 158			Adjusted for life satisfaction at baseline, n = 159
	OR (95 % CI)	Wald	value	OR (95 % CI)	Wald	value
General self-efficacy (GSE)	1.081 (1.019–1.147)	6.765	0.009
Walking difficulties (Walk-12G)	0.962 (0.929–0.997)	4.725	0.030	0.961 (0.929–0.994)	5.401	0.020
Nagelkerke R square			0.157			0.221
Hosmer and Lemeshow test, value			0.203			0.534

OR = odds ratio; CI = confidence interval; GSE = General Self-Efficacy Scale (10–40, higher = better); Walk-12G = Generic Walk-12 (0–42, higher = worse). Life satisfaction was assessed with item 1 of the Life Satisfaction Questionnaire (scored 1–6; higher = better), and scores were dichotomized into not satisfied (1–4; coded as 0) and satisfied (5-6; coded as 1). The following 7 independent variables were initially included in the models (backward method): sex; education; general self-efficacy; motor symptoms; walking difficulties; fall-related activity avoidance; difficulties with, or need help in activities of daily living. Statistically significant values (0.05) are presented in bold.
