Psychometric properties of the eating loss of control scale among postbariatric patients.

ABSTRACT: BACKGROUND:Assessing the complexities of eating behaviors in patients who undergo bariatric surgery is challenging. The Eating Loss of Control Scale (ELOCS), a measure of loss-of-control (LOC) eating, has not yet been evaluated psychometrically among bariatric surgery patients. OBJECTIVE:This study presents a psychometric examination of the ELOCS in postoperative bariatric surgery patients. SETTING:Academic medical center in the United States. METHODS:One hundred seventy-one postbariatric treatment-seeking adults (82.5% female, 52.4% white) with LOC eating completed the ELOCS and measures assessing eating psychopathology and mood. Confirmatory factor analysis (CFA) was used to test fit for a 1-factor solution. Exploratory factor analysis (EFA) examined alternative factor structures. RESULTS:CFA revealed poor fit for a 1-factor structure (?2 = 220.375, degrees of freedom = 135, P < .001, comparative fit index = .917, Tucker-Lewis index = .906, root mean square error of approximation = .067). EFA data suggested an alternative factor solution (?2 = 157.76, degrees of freedom = 118, P = .009, comparative fit index = .965, Tucker-Lewis index = .955, root mean square error of approximation = .047). Factor 1 (? = .88) reflected behavioral aspects and factor 2 (? = .92) reflected cognitive/emotional aspects of LOC eating. Bivariate correlations with measures of eating and other psychopathology suggested good construct validity for factors. CONCLUSIONS:Findings suggest possible differences in the construct validity of the ELOCS among postbariatric patients. The 1-factor solution previously supported in clinical and nonclinical groups demonstrated poor fit. EFA revealed a possible alternative 2-factor solution that aligns with emerging literature, suggesting that LOC eating presents differently in postbariatric patients. Researchers interested in LOC eating among bariatric patients should consider use of the ELOCS and testing the proposed alternative factor structure.

Project description:ObjectiveFacebook addiction is increasing, giving rise to limited real-life social networks, loneliness, poor work and academic performance, psychopathology, and low well-being. Facebook entails numerous factors that increase the risk for disordered eating attitudes and behaviors (e.g., use time and Facebook activities such as social grooming and photo sharing). This study aimed to evaluate the psychometric properties of the Bergen Facebook Addiction Scale (BFAS) among patients with eating disorders (EDs) given lack of validation of Facebook addiction measures in this population.MethodsA cross-sectional study involving 123 inpatient and outpatient women with EDs (Mean age = 27.3, SD = 10.6, range = 14-59 years) used confirmatory factor analysis (CFA), multigroup CFA, structural equation modeling (SEM), Spearman's rho Spearman's analysis, McDonald's Omega (ω), Cronbach's alpha (α), and item-total correlations to examine the structure, invariance, criterion validity, reliability, and discriminant validity of the BFAS.ResultsCorrelating the residuals of items 2, 3, and 5 resulted in an excellent fit of a one-factor structure of the BFAS (χ2(7) = 8.515, p = .289, CFI = .998, TLI = .996, RMSEA = .042, SRMR = .0099). The BFAS was invariant at the configural, metric, and scalar levels across groups of EDs, age, education, and marital status. High values of ω and α (.96) as well as item-total correlations (.851-.929) indicated excellent reliability and high discrimination index of the BFAS. Criterion validity is noted by strong positive correlation with the Six-item Internet Addiction Test (S-IAT, r = .88) and SEM using the S-IAT to predict the BFAS (χ2(49) = 103.701, p = .001, CFI = .975, TLI = .966, RMSEA = .096, SRMR = .0317)..ConclusionThe BFAS is a reliable unidimensional measure. Its high discrimination index and invariance across different groups make it useful for detecting Facebook addiction among patients with ED.
