Measurement properties of the Sexual Risk Behaviors Scale (SRBS) in university students in Brazil.

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 translate and evaluate the measurement properties of the Sexual Risk Behaviors Scale into Brazilian Portuguese for use in university students.
methodsContent validity was assessed by experts and Brazilian adults. Structural validity was assessed using a confirmatory factor analysis. Internal consistency and test-retest reliability were assessed using McDonald's Omega and intraclass correlation coefficient (ICC), respectively. Measurement invariance between females and males was evaluated using multigroup confirmatory factor analysis. The measurement error and floor and ceiling effects were also evaluated.
resultsThe experts and Brazilian adults suggested that the five-item Sexual Risk Behaviors Scale was more relevant, comprehensive, and comprehensible. In total (n=633; 22.8±2.0 years), 362 (57.2%) women and 271 (42.8%) men participated in the study. Structural validity indicated a one-factor structure as the best-fitting model, and the internal consistency was sufficient (McDonald's Omega=0.723). There was measurement invariance between females and males. The test-retest reliability was found to be sufficient (ICC=0.873). Moreover, no systematic error were observed. There was a floor effect across the entire sample.
conclusionThe Sexual Risk Behaviors Scale is valid and reliable for assessing sexual risk behaviors in university students in Brazil.
