Sex differences in PTSD symptoms : A differential item functioning approach

Objective: Evidence has suggested there are sex differences in posttraumatic stress disorder (PTSD) symptom expression; however, few studies have assessed whether these differences are due to measurement invariance. This study aimed to examine sex differences in PTSD symptoms based on the Diagnostic...

This study aimed to examine sex differences in PTSD symptoms based on the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM–5) using differential item functioning (DIF). Method: Confirmatory factor analysis was conducted on the DSM–5 model of PTSD, followed by a multiple indicators multiple causes (MIMIC) model to examine possible DIF using the PTSD Checklist for DSM–5. Data were analyzed from a Malaysian adolescent sample (n = 481) of which 61.7% were female, with a mean age of 17.03 years. Results: The results indicated the presence of DIF for 2 of 20 PTSD criteria. Females scored significantly higher on emotional cue reactivity (B4), and males reported significantly higher rates of reckless or self-destructive behavior (E2) while statistically controlling for the latent variables in the model. However, the magnitude of these item-level differences was small. Conclusion: These findings indicate that despite the presence of DIF for 2 DSM–5 symptoms, this does not provide firm support for nonequivalence across sex.
