“…Although there was evidence of scalar invariance across genders based on change in RMSEA and TLI, scalar invariance was not indicated based on change in CFI. These findings are consistent with recent work examining measurement invariance across adolescents and adults [ 20 ] and provide support for similar factor structure and factor loadings across genders; however, there may be variance at the level of the intercepts (see Table 1 ).…”

“…We first conducted confirmatory factor analyses (CFA) in MPlus version 8 to test the 8-factor structure of the F-EPSI in the overall sample as well as separately in men and women ( H1 ). Consistent with prior research [ 19 , 20 ], we employed a robust weighted least squares estimator (WLSMV), given the ordinal nature of the data. As suggested in the literature [ 33 , 34 ], model fit was assessed using the following indices: root mean square error of approximation (RMSEA; < 0.08 indicates a good model fit), the comparative fit index (CFI; > 0.90 indicates an adequate model fit), and the Tucker–Lewis index (TLI; > 0.90 indicates an adequate model fit).…”

“…The 45-item version has demonstrated a robust eight-factor structure in university men and women in the US [ 17 ] and China [ 18 ] as well as in outpatients with eating disorders in the US [ 19 ]. Furthermore, the EPSI was invariant by gender [ 16 ] and age [ 20 ], suggesting that the EPSI can be compared across genders [ 21 ]. Studies from the US and China comparing EPSI scores across genders found that women reported higher scores than men on all subscales except excessive exercise, muscle building, and negative attitudes toward obesity [ 17 , 18 , 22 ].…”

Psychometric properties of the Farsi version of the Eating Pathology Symptoms Inventory (F-EPSI) among Iranian University men and women

Background Limited research has validated eating pathology assessments in Iranian men and women. The purpose of the current study was to translate and validate a Farsi version of the Eating Pathology Symptoms Inventory (F-EPSI) in Iranian university students. Methods Men (n = 279) and women (n = 486) completed questionnaires including the F-EPSI. Results Confirmatory factor analysis (CFA) indicated that the F-EPSI had an acceptable fit to the data and supported the eight-factor model. The scale was partially invariant across genders. Men reported higher scores on Excessive Exercise and Muscle Building subscales, and women reported higher scores on Body Dissatisfaction and Restricting subscales. The F-EPSI subscales had good 5- to 6-month test–retest reliability. The F-EPSI demonstrated convergent validity with clinical impairment, eating pathology, and body mass index (BMI). Finally, individuals scoring above the Clinical Impairment Assessment (CIA) cutoffs reported higher scores on the F-EPSI subscales, further supporting convergent validity of the scale. Conclusion Findings suggest that the F-EPSI will enable researchers to examine eating pathology symptoms among men and women in Iran.

“…In example 7 of supplementary material, we apply mixture modeling to the attention problems syndrome scale of the CBCL because it is designed to assess attention problems related to ADHD 69,93 and ADHD is increasingly recognized as a heterogeneous disorder [192][193][194][195] . We find that a two-class, one-factor model provides the best fit to the data.…”

Our capacity to measure diverse aspects of human biology in vivo has developed rapidly in the past decades, but the rate at which these techniques have generated translatable insights into the biology of psychopathological conditions has lagged far behind. This slow progress is partly due to the poor sensitivity, specificity, and replicability of many findings in the literature, which have in turn been attributed to small effect sizes, small sample sizes, and low statistical power. A commonly proposed solution is to rely on large, consortia-sized samples to facilitate discovery of replicable findings. Here, we argue that increasing sample sizes will have limited impact unless a more fundamental issue is addressed: the precision with which target behavioral phenotypes are measured. We discuss key problems and outline several ways forward, largely centered on the use of appropriate statistical models with deep, transdiagnostic assessment of hierarchically organized and homogeneous psychopathology dimensions across the full range of the severity spectrum. We provide worked examples to demonstrate key problems and potential solutions. Arguably, a precision phenotyping approach can enhance the discovery and replicability of associations between biology and behavior, thereby facilitating insights into the pathophysiological mechanisms underlying psychiatric disorders.

“…Scores range from 0 to 220. This measure has strong psychometric properties, including high test–retest reliability and an invariant factor structure across development (Forbush et al, 2013; Richson et al, 2021). Higher scores reflect more frequent thoughts, feelings, and behaviors associated with eating disorders.…”

Background: Research indicates that difficulties across multiple socioemotional functioning domains (e.g., social emotion expression/regulation, response to social elicitors of emotion) and negatively biased interpretations of ambiguous social situations may affect eating disorder symptoms. The impact of inflexible interpretations of social situations on eating disorder symptoms is less clear. The present study therefore examined relations between inflexible and biased social interpretations, socioemotional functioning, and eating disorder symptoms.Method: A total of 310 participants from the general population, recruited from an online crowdsourcing platform, completed measures of socioemotional functioning (e.g., rejection sensitivity, negative social exchange), eating disorder symptoms, and positive and negative interpretation bias and inflexibility on a single measurement occasion.Results: Socioemotional functioning impairments (Pillai's trace = 0.11, p < .001), but not negative (β = .07, p = .162) or positive (β = À.01, p = .804) interpretation bias or inflexible interpretations (β = .04, p = .446), were associated with eating disorder symptoms in multiple regression models. In network analyses controlling statistically for multiple markers of socioemotional functioning, eating disorder symptoms were directly associated with negative (but not positive) interpretation bias. Inflexible interpretations were indirectly linked to symptoms via co-dampening of positive emotions. Exploratory causal discovery analyses suggested that several socioemotional functioning variables (social anxiety, depression, negative social exchange) may cause eating disorder symptoms.Conclusions: Consistent with cognitive-interpersonal models of disordered eating, our results suggest that less accurate (biased, inflexible) interpretations of social information contribute to patterns of cognition (anxious anticipation of rejection) and emotion regulation (down-regulation of positive social emotion) thought to encourage disordered eating.Public Significance: This study suggests that less accurate interpretations of ambiguous social information encourage anxious anticipation of rejection and downregulation of positive social emotions, both of which are thought to promote eating disorder symptoms. Knowledge provided by this study about the likely relations between interpretive processes, social/emotional functioning, and eating disorder symptoms may help inform treatments for eating disorders, particularly those that attempt to modify patterns of interpretation.
