“…There is some evidence that indicates self‐motivation, self‐determination, RTC, and self‐efficacy may play a small role in predicting short‐term weight outcomes (17,18,19,20,21,22,23). An assessment of the specifically designed “Dieting Readiness Test” found it to be a poor predictor of weight loss and treatment attendance (24) and of little practical value (25). However, there is evidence that a greater level of motivation to lose weight or RTC is associated with better improvement in food selection and dietary composition (26,27).…”

High levels of readiness to change (RTC) are considered critical to the long‐term success of weight management programs including bariatric surgery. However, there are no data to support this assertion. We hypothesize that RTC level will not influence weight outcomes following surgery. In 227 consecutive patients undergoing adjustable gastric banding surgery, we recorded reasons for seeking surgery, and RTC measured with the University of Rhode Island Change Assessment. Scores were blinded until study completion. The primary outcome measure was percentage of excess BMI loss at 2 years (%EBMIL‐2); others included compliance and surgical complications. Of 227 subjects, 204 (90%) had weight measurement at 2 years. There was no significant correlation between RTC score and %EBMIL‐2 (r = 0.047, P = 0.5). Using the median split for RTC score the lowest 102 subjects mean %EBMIL‐2 was 52.9 ± 26.9% and the highest 52.2 ± 28.3%, P = 0.869. There was no weight loss difference between highest and lowest quartiles, or a nonlinear relationship between weight loss and RTC score. There was no significant relationship between RCT score and compliance, or likelihood of complications. Those motivated by appearance were more likely to be younger women who lost more weight at 2 years. Poor attendance at follow‐up visits was associated with less weight loss, especially in men. Measures of RTC did not predict weight loss, compliance, or surgical complications. Caution is advised when using assessments of RTC to predict outcomes of bariatric surgery.

Psychological and behavioural factors associated with long-term weight maintenance after a multidisciplinary treatment of uncomplicated obesity

Obesity is a multifactorial syndrome and the likelihood of success of a medical nutritional treatment (MNT) over the long term is low. As psychological and behavioural factors have an important role in both pathogenesis and the treatment of obesity, these issues were investigated in individuals with obesity who reported a long-term success or a failure in terms of weight loss following a MNT. Eighty-eight individuals of an original cohort of 251 subjects were re-evaluated 10 years after a MNT with cognitive-behavioural approach for uncomplicated obesity. Fifty-three participants were classified as failure (body weight change ≥0.5 kg) and 35 as a success (10-year body weight change <0.5 kg) of the MNT. Prior to the beginning of the weight-management program, both the Dieting Readiness Test (DRT) and the Hospital Anxiety and Depression Scale (HADS) were administered. At a 10-year follow-up after the MNT, self-reported questionnaires were administered: quality of life was assessed by the Obesity Related Well-Being (ORWELL 97) questionnaire, eating attitudes and behaviours by the Eating Disorder Examination Questionnaire (EDE-Q), the Binge Eating Scale (BES) investigated the presence and severity of binge eating and the Symptom Checklist (SCL 90-R) was used to identify the psychopathological distress. The scores of the ORWELL 97 items concerning symptoms (P = 0.005), discomfort (P = 0.03) and the total score (P = 0.02) were significantly lower in the success group. The depression score of the HADS was positively correlated with the percentage of body weight change observed 10 years after the MNT (r = 0.22; P = 0.045). The scores of the shape concern (EDE-Q) (r = 0.35; P = 0.013) and of the discomfort (ORWELL 97) (r = 0.36; P = 0.012) were significantly correlated with the percentage of body weight change 10 years after the MNT. In conclusion, this study is in agreement with the possibility that the psychological quality of life is associated even with modest amounts of weight loss in the long run. Further research should support identifying successful predictors of weight loss.
