Abstract

Post-traumatic stress disorder (PTSD) should be one of the most preventable mental disorders, since many people exposed to traumatic experiences (TEs) could be targeted in first response settings in the immediate aftermath of exposure for preventive intervention. However, these interventions are costly and the proportion of TE-exposed people who develop PTSD is small. To be cost-effective, risk prediction rules are needed to target high-risk people in the immediate aftermath of a TE. Although a number of studies have been carried out to examine prospective predictors of PTSD among people recently exposed to TEs, most were either small or focused on a narrow sample, making it unclear how well PTSD can be predicted in the total population of people exposed to TEs. The current report investigates this issue in a large sample based on the World Health Organization (WHO)'s World Mental Health Surveys. Retrospective reports were obtained on the predictors of PTSD associated with 47,466 TE exposures in representative community surveys carried out in 24 countries. Machine learning methods (random forests, penalized regression, super learner) were used to develop a model predicting PTSD from information about TE type, socio-demographics, and prior histories of cumulative TE exposure and DSM-IV disorders. DSM-IV PTSD prevalence was 4.0% across the 47,466 TE exposures. 95.6% of these PTSD cases were associated with the 10.0% of exposures (i.e., 4,747) classified by machine learning algorithm as having highest predicted PTSD risk. The 47,466 exposures were divided into 20 ventiles (20 groups of equal size) ranked by predicted PTSD risk. PTSD occurred after 56.3% of the TEs in the highest-risk ventile, 20.0% of the TEs in the second highest ventile, and 0.0-1.3% of the TEs in the 18 remaining ventiles. These patterns of differential risk were quite stable across demographic-geographic sub-samples. These results demonstrate that a sensitive risk algorithm can be created using data collected in the immediate aftermath of TE exposure to target people at highest risk of PTSD. However, validation of the algorithm is needed in prospective samples, and additional work is warranted to refine the algorithm both in terms of determining a minimum required predictor set and developing a practical administration and scoring protocol that can be used in routine clinical practice.

  • The comparisons of findings to prior meta-analyses indirectly corroborate that sexual assault may be associated with greater prevalence and symptom severity of PTSD relative to other forms of trauma.

    “these comparisons of our findings to prior meta-analyses indirectly corroborate extant literature suggesting sexual assault may be associated with greater prevalence and symptom severity of PTSD relative to other forms of trauma”

    The “Distribution and associations of TEs with PTSD” section reports higher conditional PTSD risk after rape and other sexual assault than after many other traumatic experiences. The paper also describes prior meta-analyses as linking physical or sexual assault to high PTSD risk, but the passages do not establish greater PTSD symptom severity after sexual assault.

  • Sexual assault is associated with higher rates of PTSD than other traumas.

    “Sexual assault is associated with higher rates of PTSD than other traumas (Brewin et al., 2000; Dworkin, 2020; Kessler et al., 2014; Kilpatrick et al., 2003)”

  • Sexual assault appears to carry relatively greater risk for PTSD than other potentially traumatic events.

    “Compared to other potentially traumatic events (e.g., physical assault, accidents, natural disasters), for which only a minority of survivors experience significant levels of PTSD (Galatzer-Levy et al., 2018; Lowe et al., 2020), sexual assault appears to carry relatively greater risk for PTSD (Brewin et al., 2000; Dworkin, 2020; Kessler et al., 2014; Kilpatrick et al., 2003), and may be associated”

  • No prior work has quantitatively summarized the natural course of PTSD recovery specifically for adolescent and adult sexual assault survivors.

    “Second, despite evidence that sexual assault is more strongly associated with PTSD than other forms of trauma (Brewin et al., 2000; Dworkin, 2020; Kessler et al., 2014; Kilpatrick et al., 2003), no prior work has quantitatively summarized the natural course of PTSD recovery specifically for adolescent and adult sexual assault survivors.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
