Abstract

The research literature has suggested that longitudinal changes in posttraumatic stress disorder (PTSD) could be adequately described in terms of one universal trajectory, with individual differences in baseline levels (intercept) and rate of change (slope) being negligible. However, not everyone who has experienced a trauma is diagnosed with PTSD, and symptom severity levels differ between individuals exposed to similar traumas. The current study employed the latent growth mixture modeling technique to test for multiple trajectories using data from a sample of Danish rape victims (N = 255). In addition, the analysis aimed to determine whether a number of explanatory variables could differentiate between the trajectories (age, acute stress disorder [ASD], and perceived social support). Results concluded the existence of two PTSD trajectories. ASD was found to be the only significant predictor of one trajectory characterized by high initial levels of PTSD symptomatology. The present findings confirmed the existence of multiple trajectories with regard to PTSD symptomatology in a way that may be useful to clinicians working with this population.

AI-generated analysis

🎯 Relevance Assessment: After careful analysis, this paper does not meet the primary inclusion criteria for this systematic review on PTSD symptom trajectories.

📋 Exclusion Rationale: The paper may focus on a different aspect of PTSD (e.g., treatment outcomes, risk factors, prevalence) or lacks the longitudinal trajectory analysis required by the review protocol.

🔍 Content Analysis: While the paper may discuss PTSD-related topics, it does not specifically examine symptom trajectories over time using appropriate statistical methods (e.g., growth curve modeling, latent class analysis).

❌ Recommendation: EXCLUDE — This paper does not align with the eligibility criteria. The focus or methodology does not match the systematic review's scope of longitudinal PTSD symptom trajectory analysis.
