	Adjusted model
Independent variables	OR	p	95% CI
Age increase in 10 years	0.88	<  0.01	0.80–0.96
Gender (male vs. female)	1.17	0.29	0.88–1.55
Education (≤12 yrs. vs. >  12 yrs.)	0.75	0.05	0.57–1.00
Working (no vs. yes)	0.71	<  0.05	0.53–0.95
General self-efficacy (mean)	0.75	< 0.05	0.58–0.95

Neuroticism (sum)	1.74	< 0.001	1.60–1.88

Note. Reference categories are lower age, male gender, lower education, not working, and lower levels of general self-efficacy, optimism, extraversion, and neuroticism. Adjusted model parameters: Nagelkerke R² = 0.31, Cox & Snell R² = 0.20, Model χ² = 361.60, p < 0.001. Hosmer Lemeshow: χ² = 12.9, p = 0.11
