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 = 0.33, Cox & Snell R² = 0.13, Model χ² = 218.46, p <  0.001. Hosmer Lemeshow: χ² = 6.79, p = 0.56
