Summary
The Posttrauma Risky Behaviors Questionnaire (PRBQ) shows good psychometric properties for assessing posttrauma reckless and self-destructive behaviors (RSDBs). It is suitable for comparing RSDBs across diverse groups and genders.
Area of Science:
- Psychology
- Psychometrics
- Trauma Studies
Background:
- The Posttrauma Risky Behaviors Questionnaire (PRBQ) is a recent tool for assessing posttrauma reckless and self-destructive behaviors (RSDBs).
- Limited psychometric investigations necessitate further validation of the PRBQ.
Purpose of the Study:
- To evaluate the psychometric properties of the PRBQ using item response theory.
- To examine item analysis, person fit, and differential item functioning (DIF) across gender and samples.
Main Methods:
- Item response theory analysis was applied to two distinct samples: 464 online participants (MTurk) and 171 women experiencing intimate partner violence.
- Analysis included item analysis, person fit assessment, and DIF analysis across gender and samples.
Main Results:
- All PRBQ items contributed to the RSDB scale, with maximum information for high levels of the RSDB latent trait.
- Some items were identified as low information items in both samples. Eight participants showed poor person fit in the MTurk sample.
- Seven items showed DIF between samples, and eight items showed DIF between genders in the MTurk sample, with small effect sizes (<8%).
Conclusions:
- The PRBQ demonstrates good psychometric properties.
- The findings support the PRBQ's utility for comparing RSDBs across different samples and gender groups.
