Reliability and validity of the Japanese translation of the Eating Disorders Quality of Life (ED-QOL) scale for Japanese healthy female university undergraduate students and patients with eating disorders.

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
backgroundThe Eating Disorder Quality of Life (ED-QOL) scale is a 25-item self-report measure that assesses health-related quality of life (HRQoL) of eating-disorder patients. Although the ED-QOL is one of the most widely used questionnaires in many countries, no prior research has addressed the psychometric properties of the Japanese translation of the ED-QOL. Therefore, the aim of the present study was to assess its reliability and validity.
methodsA total of 99 Japanese female eating disorder patients and 469 female healthy university undergraduate students completed the Japanese translation of the ED-QOL in addition to the Eating Attitudes Test-26 (EAT-26) and Eating Disorder Inventory-2 (EDI-2). The patient group consisted of 37 patients with anorexia nervosa restricting type (AN-R), 35 patients with binge-eating/purge type (AN-BP), and 27 patients with bulimia nervosa (BN). We performed confirmatory factor analyses on the ED-QOL subscales both for Japanese eating disorder patients and for healthy university undergraduate students. Reliability was assessed using internal consistency indicated by Cronbach alpha coefficients and convergent validity was assessed using Pearson's correlation coefficients. To assess group differences between the eating disorder patients and healthy university undergraduate students, Student's t-tests were conducted.
resultsThe CFA showed that the CFI was .90 and RMSEA was .084 (90% confidence interval = .079-.088). The internal consistency of the ED-QOL varied from good to excellent. The EAT-26 total score and three subscales and the EDI-2 subscales had significant correlations with the ED-QOL global QOL score and four subscales. There were no significant correlations between the EDI-2 subscale "Body Dissatisfaction" and the ED-QOL subscales "Physical/Cognitive" and "Work/School". Eating disorder patients scored significantly higher than healthy university undergraduate students on all ED-QOL subscales and the global QOL score.
conclusionsBased on this study, the Japanese translation of the ED-QOL can be regarded as reliable, valid, and functional for female eating-disorder patients and female healthy university undergraduate students.
