Factor Structure, Internal Consistency, and Measurement Invariance of the Eating Pathology Symptoms Inventory (EPSI) in Transgender and Gender-Diverse Adults.
Article in The International journal of eating disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study aimed to examine the psychometric properties, including factor structure, internal consistency, and measurement invariance of the Eating Pathology Symptoms Inventory (EPSI) in a large national sample of transgender and gender-diverse (TGD) adults.
methodThe sample consisted of 2098 TGD adults-including transgender men (n = 599), transgender women (n = 293), and gender-diverse individuals (n = 1206)-who completed online self-report surveys. Using a subset of the sample, exploratory factor analysis (EFA) was conducted to identify underlying factor structures, followed by confirmatory factor analysis (CFA) to confirm the model fit within each population in the remainder of the sample. Multi-group confirmatory factor analysis (MG-CFA) was used to assess measurement invariance across transgender men, transgender women, and gender-diverse individuals.
resultsThe EPSI's eight-factor structure was supported across all three TGD groups with strong model fit: transgender men (CFI = 0.985, RMSEA = 0.047, SRMR = 0.078), transgender women (CFI = 0.948, RMSEA = 0.048, SRMR = 0.085), and gender-diverse individuals (CFI = 0.962, RMSEA = 0.040, SRMR = 0.060). Measurement invariance analyses supported that the EPSI was invariant across the groups, facilitating meaningful group comparisons using the inventory. Internal consistency, assessed using McDonald's omega, was acceptable for all subscales (ω = 0.74-0.94). DISCUSSION: This study provides psychometric support for the EPSI in TGD groups. The results indicate that the EPSI performs reliably and consistently across these groups for assessing eating pathology among gender minority people.
