Self-efficacy, fear and response efficacy were independently associated with intention to change health-related behavior in multivariable regression analysis (Table 3). After adjustment for age, sex, event type, score on CES-D, and score on the MoCA, self-efficacy was the strongest determinant of intention to change physical activity (aBeta 0.40; 95% CI 0.12-0.71), diet (aBeta 0.49; 95% CI 0.23-0.75) and smoking (aBeta 0.51; 95% CI 0.13-0.88). We found no interactions between age, sex, depression, cognitive performance and event type on the one hand and sociocognitive factors on the other (data not shown).
