“…The scale consists of 25 items and two factors: Negative Affect (NA) and Socially Acceptable Circumstances (SAC). The ESES demonstrated good internal consistency, test-retest reliability, and convergent validity [ 15 ].The WEL has been validated in the Spanish population [ 16 ]. The results did not support the five-subscale structure initially proposed by Clark et al [ 14 ], as only three were confirmed: negative emotions, social pressure, and physical discomfort.…”

“…This is the case of Item 12: "I can resist eating even when I am at a party". There are most likely other social events in Spanish culture where food is always on hand (e.g., first communions, baptisms, and weddings); however, this is not the case with "fiestas" or parties, where drinks and music play a much more important role than food, which may or may not be served [ 16 ]. This example is consistent with Chilean culture and its legacy of Spanish customs, resulting in Chilean social practices being more similar to Spanish ones than those in the English version of the scale.…”

Self-efficacy is a cognitive-emotional factor that is consistently associated with behavioral change and, in particular, with changes in health behavior. Eating self-efficacy, understood as adopting and maintaining behaviors such as controlling one’s weight and trusting in one’s ability to control one’s eating behavior, has been proposed for managing obesity. This study aimed to validate the Chilean version of the Weight Efficacy Lifestyle Questionnaire (WEL) in a sample of adults from the general population. Four hundred sixty-nine individuals (69.08% women, mean age = 38.02; SD = 10.31) participated in the study. An instrumental design was used geared toward developing tests and psychometric instruments, including adapting existing ones. Exploratory and confirmatory factor analyses were performed. The instrument version validated in Spain was applied in the study. The analysis obtained an instrument of 11 items with adequate psychometric properties allowing its use in clinical and research settings. It can help assess eating self-efficacy in the general population.

“…Self-efficacy for weight control is measured with the Weight Efficacy Lifestyle Questionnaire–Short Form, an 8-item measure of confidence (on a 10-point scale) managing five situational factors related to weight management behavior: negative emotions, availability, social pressure, physical discomfort, and positive activities [ 21 ]. We use validated Spanish-language versions of both measures [ 25 , 26 ]. Weight loss readiness is assessed with the Stages of Change in Overweight and Obese People (S-Weight), a 5-item survey developed concurrently in English and Spanish by expert consensus [ 22 , 23 ].…”

Enhanced Enrollment in the National Diabetes Prevention Program to Increase Engagement and Weight Loss for the Underserved: Protocol for a Randomized Controlled Trial

et al. 2020

Background Type 2 diabetes affects 9.4% of US adults with higher rates among racial and ethnic minorities and individuals of low socioeconomic status. The National Diabetes Prevention Program (NDPP) is an evidence-based and widely disseminated behavioral intervention to reduce diabetes incidence through modest weight loss. However, retention in the yearlong NDPP is problematic and leads to suboptimal weight loss, especially among diverse, underserved populations. Strategies to improve NDPP engagement and weight loss are needed urgently. Pilot results of the pre-NDPP, a novel enhancement to enrollment in the NDPP based on the Health Belief Model, were highly successful in a nonrandomized cohort study among 1140 racially diverse, predominately low-income participants. A total of 75 presession participants had doubled attendance and weight loss as compared with earlier participants who did not receive presessions. On the basis of these promising results, we are conducting a randomized controlled trial (RCT) to determine whether pre-NDPP reliably improves NDPP outcomes, as reported on ClinicalTrials.gov. Objective This study aims to (1) conduct an RCT comparing NDPP attendance and weight loss outcomes between participants who receive pre-NDPP versus direct enrollment into the NDPP (usual care), (2) examine potential effect mediators (perceived risk for developing diabetes and self-efficacy and readiness for weight control) and moderators (race and ethnicity; income level), and (3) evaluate implementation factors, including cost and projected return on investment. Methods This two-arm RCT will compare outcomes among diverse, predominately low-income participants who receive pre-NDPP versus direct enrollment into the NDPP (usual care). This is a type 1 hybrid effectiveness-implementation design to determine clinical effectiveness through an RCT, while assessing factors that may impact future pre-NDPP dissemination and implementation, including cost. Our primary research question is whether pre-NDPP improves NDPP attendance and weight loss compared with standard NDPP delivery. Results This project was funded in April 2019. Recruitment is underway as of July 2019. Initial participants began the intervention in October 2019. Data analysis and results reporting are expected to be completed in 2024. Conclusions This RCT of pre-NDPP may lead to future dissemination of a scalable, evidence-based strategy to improve success of the NDPP, reduce disparities in NDPP effectiveness, and help prevent type 2 diabetes across the country.
