Using Latent Variable Mixture Modeling to Understand Trauma-Related Outcomes in Undergraduate Women

Posttraumatic stress disorder (PTSD) and sexual functioning problems often co-occur after trauma. Researchers have linked certain factors (e.g., depression, relationship satisfaction) to PTSD and sexual functioning, but it is unclear how these variables interact. Adult undergraduate female trauma survivors (N = 280) completed self-report measures via an online survey. Latent variable mixture modeling generated four groups that differed in terms of their PTSD symptom severity, sexual functioning, sexual pain, relationship status, and relationship functioning. ANOVAs explored group differences. Classes were not differentiated by trauma, relationship satisfaction, or drug use. Results highlight the complex relations between sexual functioning and post-trauma symptomology.
