Mindful eating questionnaire: Validation and reliability in Brazilian adults with type 2 diabetes mellitus. Appetite 2024; 195:107228. [PMID: 38278444 DOI: 10.1016/j.appet.2024.107228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 01/09/2024] [Accepted: 01/17/2024] [Indexed: 01/28/2024]
Abstract
OBJECTIVE The objective was to evaluate the psychometric properties of the Mindful Eating Questionnaire (MEQ) in Brazilian subjects with type 2 diabetes mellitus (T2DM) and validate a Brazilian version of the MEQ for adults with T2DM (MEQ-DM). METHODOLOGY Baseline data from the multicentre Nutritional Strategy for Glycaemic Control in Patients with Type 2 Diabetes Mellitus (NUGLIC) trial were used. Construct validity was assessed using exploratory factor analysis (EFA). The root mean square error of approximation (RMSEA), comparative fit index (CFI) and Tucker‒Lewis index (TLI) fit indices indicated the adequacy of the model. The reliability of the questionnaire was evaluated considering the different factor loadings. Criterion validity was tested by correlating the MEQ-DM with sociodemographic variables, body mass index (BMI) and physical activity levels. RESULTS A total of 370 participants were included, who were mostly female (60.8 %) and had a median age of 61 (54-67) years. The EFA results supported the two-factor structure of the 25-item MEQ-DM: disinhibition and awareness. The results of the fit indices (RMSEA = 0.04; CFI = 0.95 and TLI = 0.94) and composite reliability (disinhibition = 0.84 and awareness = 0.81) were consistent. The criterion validity analysis indicated a significant association between MEQ-DM scores and age, sex, civil status, education level, BMI and physical activity (p < 0.05). CONCLUSION When explored with Brazilian adults with T2DM, the MEQ-DM presented a factorial model with two dimensions: disinhibition and awareness. This model must be confirmed in future studies with Brazilians with T2DM.

Zhang Q, O'Connor DB, Hugh-Jones S. Feasibility of a multiple-component mindfulness intervention for Chinese adolescents living with overweight: A pilot randomized trial. Appl Psychol Health Well Being 2022; 15:516-535. [PMID: 35860947 DOI: 10.1111/aphw.12393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Accepted: 07/10/2022] [Indexed: 11/27/2022]
Abstract
The prevalence of obesity among Chinese adolescents is rising rapidly, and theoretically informed, scalable weight management interventions are needed. We developed and evaluated the feasibility and preliminary effects of an mHealth nutrition education and mindful snacking intervention for weight loss and improved dietary practices among Chinese adolescents with overweight. We examined whether including implementation intention formation (using if-then plans) improved outcomes. With user consultation, we created a 3-week mindful eating intervention delivered as 10 videos to user smartphones. Participants (n = 55) were randomly assigned to mindful eating or mindful eating + planning. Forty-six (83.6%) participants (age = 16.35 ± 0.48 years; body mass index [BMI] = 25.79 ± 2.05 kg/m2 ) completed the intervention. Both groups exhibited significant pre- to post-intervention weight loss (M = 1.42 and 1.79 kg, respectively); decreases in snacking frequencies, emotional eating, external eating, and trait craving; and significant increases in mindful eating and eating self-efficacy. No significant intervention group differences were observed. User experience data (n = 16) indicated acceptability and meaningful behavior change. Findings suggest that a smartphone-delivered mindfulness-based intervention for Chinese adolescents living with overweight is feasible and efficacious.
