Identification of instruments for evaluation of behavioural and psychological parameters associated with obesity management: A systematic review with narrative synthesis of the findings

Abstract Background and aims To identify instruments to evaluate the predictors of successful weight loss across weight loss trials. Methods We searched PubMed, PsychInfo, Cochrane Reviews and Scopus for weight loss trials reporting instruments published in the last 16 years. Results A total of 46 significant behavioral and psychological predictors were identified, of which 32 instruments were finally selected. SF-36 questionnaire and Obesity Related Problem Scale for psychosocial health, TREMORE scale for motivation, Social Support Scale for support, Weight Efficacy Lifestyle Scale for self-efficacy and Body Shape Questionnaire for body image had moderate quality. Barriers to healthy eating questionnaire scale and Dutch Eating Behavior had moderate quality. Conclusion Use of uniform instruments with optimum quality can benefit clinical and community-based researchers to generate reliable datasets.
