Comparing Questionnaires for Assessing Orthorexic Thoughts and Behaviors in College Students.

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
Mindful eating (ME) is becoming increasingly popular as a method of changing problematic eating behaviors, including orthorexic (ON) thoughts and behaviors. Simultaneously, the psychometric flaws of commonly used questionnaires for assessing ON thoughts and behaviors limit the potential of exploring their association with ME and diet quality. The study aimed to (a) assess the intensity of ON thoughts and behaviors; (b) evaluate the associations between ON thoughts and behaviors, ME, and diet quality; and (c) compare ORTO-R with ORTO-15 and its shortened versions and PL-DOS. Data were collected from a sample of 478 college students through a cross-sectional study conducted in 2021 across eighteen universities in Poland. Students completed the ORTO-R, ORTO-15, Düsseldorf Orthorexia Scale (PL-DOS), Mindful Eating Scale (MES), and Dietary Habits and Nutrition Beliefs Questionnaire (KomPAN). ORTO-15 and its shortened versions correlated at least highly positively with each other for both sexes, as did ORTO-R and PL-DOS. Positive correlations were found between ORTO-15 and its shortened versions and such mindful eating behaviors as act with awareness as well as awareness for females and/or males. Meanwhile, ORTO-R correlated negatively with act with awareness and acceptance for females and/or males. In addition, PL-DOS correlated negatively with awareness and acceptance for females and/or males. An increase in the intensity of ON thoughts and behaviors measured by almost all questionnaires was associated with an increase in the intensity of beneficial dietary characteristics for health (higher the "Pro-Healthy Diet Index"-pHDI, and the "Diet Quality Index"-DQI) and a decrease in the intensity of harmful dietary characteristics for health (lower the "Non-Healthy Diet Index"-nHDI). Overall, ORTO-R and PL-DOS proved to be the most effective questionnaires for distinguishing eating behaviors in the context of orthorexic thoughts and behaviors, but only for ME. The results may suggest that ME practices may be associated with reduced ON thoughts and behaviors. However, limitations of the study, for example, a sample of college students, a non-randomly selected of sample, a cross-sectional design of the study, and an imbalanced biological sex ratio, make it much more difficult to generalize the results.
