Self-efficacy for eating predicts successful weight loss and maintenance in Type 2 Diabetes Mellitus (T2DM) individuals. The Weight Efficacy Lifestyle (WEL) questionnaire determines self-efficacy for controlling eating. This study aims to validate the Malay-translated version of the WEL questionnaire and to establish the cut-off scores to define the level of eating self-efficacy in Malaysian T2DM individuals. Methods: A total of 334 T2DM individuals aged 55.09.0 years were recruited from a primary healthcare clinic based on sampling ratio. Medical records were reviewed for eligibility. Inclusion criteria included BMI 23kg/m2 and no severe diabetes complications. The WEL questionnaire assessed eating resistance during negative emotions food availability social pressure physical discomfort and positive activities and was back translated into Malay language. Self-efficacy was rated on a 0-9 scale with higher WEL scores indicating greater self-efficacy to resist eating. Factor analysis established the factor structure of the WEL questionnaire. Inter-item and item-total correlations determined construct validity while internal consistency described the reliability of the structure. Results: A two-factor structure accounting for 49 of variance was obtained and it had adequate reliability as indicated by Cronbachs of 0.893 and 0.781 respectively. Item-total correlations of r0.700 p0.01 and inter-item correlations of r0.500 p0.01 demonstrated construct validity. Cut-off scores of 44 and 32 respectively for factor one and two defined high eating self-efficacies in T2DM individuals. Conclusion: The Malay translated version of the WEL questionnaire appears to be a valid and reliable tool to assess self-efficacy for controlling eating behaviour in Malaysian T2DM population.

Abstract

Self-efficacy for eating predicts successful weight loss and maintenance in Type 2 Diabetes Mellitus (T2DM) individuals. The Weight Efficacy Lifestyle (WEL) questionnaire determines self-efficacy for controlling eating. This study aims to validate the Malay-translated version of the WEL questionnaire and to establish the cut-off scores to define the level of eating self-efficacy in Malaysian T2DM individuals. Methods: A total of 334 T2DM individuals aged 55.09.0 years were recruited from a primary healthcare clinic based on sampling ratio. Medical records were reviewed for eligibility. Inclusion criteria included BMI 23kg/m2 and no severe diabetes complications. The WEL questionnaire assessed eating resistance during negative emotions food availability social pressure physical discomfort and positive activities and was back translated into Malay language. Self-efficacy was rated on a 0-9 scale with higher WEL scores indicating greater self-efficacy to resist eating. Factor analysis established the factor structure of the WEL questionnaire. Inter-item and item-total correlations determined construct validity while internal consistency described the reliability of the structure. Results: A two-factor structure accounting for 49 of variance was obtained and it had adequate reliability as indicated by Cronbachs of 0.893 and 0.781 respectively. Item-total correlations of r0.700 p0.01 and inter-item correlations of r0.500 p0.01 demonstrated construct validity. Cut-off scores of 44 and 32 respectively for factor one and two defined high eating self-efficacies in T2DM individuals. Conclusion: The Malay translated version of the WEL questionnaire appears to be a valid and reliable tool to assess self-efficacy for controlling eating behaviour in Malaysian T2DM population.
