As female addicts are more vulnerable, have greater psychological trauma and higher incidence of PTSD, this study intends to explore the impact of the revised symptom criteria on the semiotics symptomatology of PTSD (prevalence rate, phenotype model) based on the data of 862 female forced drug abstainer from a drug treatment center in sichuan province. Exploring this effect can accumulate empirical evidence for the applicability of diagnostic revisions and further provide some data support for the intervention and treatment of PTSD in special groups with drug addiction.
Therefore, the first study explored the prevalence rate and symptom frequency of PTSD in specific trauma sample groups based on DSM-5 diagnostic criteria. The applicability of symptom items was clarified through IRT, so as to explore the influence of symptom revision on the prevalence rate of PTSD. In addition to the prevalence and applicability of items, the revision of symptom criteria has also had an impact on the clinical structure of PTSD.To explore this effect, the second study firstly explored the optimal clinical phenotype model of this population from the perspective of internal fitting based on sample data. Secondly, through the introduction of external calibration standards, the factor heterogeneity of the optimal model explored in this study was verified, so as to further accumulate empirical evidence.
The results showed that the likely positive rate of PTSD in this sample group was 18.6%. In addition, IRT results showed that among the symptom clusters of B, item B3 (flashback) was the most difficult, while the degree of differentiation was the least.C. There is little difference in the difficulty and differentiation degree of each item of symptom cluster;Among the D/E symptom clusters, D1 (traumatic amnesia) /E2 (reckless behavior) items were the most difficult and the least differentiated. Finally, the seven-dimensional mixed model of female trauma population with drug addiction is the best internal fitting model.The correlation between motion impulsivity and externalized behavior factor is significantly higher than that between motion impulsivity and other heterogeneous factors, which provides empirical support for the independence of this factor. The findings of this study indicate that this group is a group with high trauma and disease, which deserves researchers' continuous attention. The applicability of the above items in this group is not very good; Overall, the findings support the applicability of DSM-5 diagnostic criteria to this group. Finally, a seven-dimensional hybrid model is recommended for clinical evaluation of this population.
