Background: Sustainable dietary, behavioural and lifestyle changes are necessary to accomplish weight loss. Aim: Evaluate impact of internal motivation, locus of control and self-efficacy on non-surgical weight loss treatment in patients with severe obesity. Methods: A total of 1196 patients, Body Mass Index ≥35 kg/m2, referred to obesity treatment were included. Visual analogue scales for motivation, locus of control and self-efficacy were completed before starting weight loss treatment. Results: A total of 601 patients (42% drop out) completed 12-month weight loss treatment. After 12 months, 94.6% in the Very Low Energy Diet (VLED) group and 79.4% in the dietary treatment group had a weight loss of ≥5% of their body weight. No statistically significant associations were found between achieved weight loss in the VLED group, and locus of control or self-efficacy. Achieving ≥15% weight loss by dietary treatment was related to a higher score on self-efficacy compared to those who lost <5% in weight or dropped out. Conclusion: Self-efficacy appears to be important for weight loss when on dietary treatment without VLED. Attrition rate was higher among patients with lower score on self-efficacy at baseline. The study indicates that psychological factors associated with adherence to, and completion of weight loss treatment deserve attention.
