Abstract
Objective To evaluate the heterogeneity in treatment effect in posttraumatic stress disorder (PTSD) trials. Patients and Methods We downloaded data from a publicly available repository that captured PTSD trials published from January 1988 through February 2023. We applied restricted maximum-likelihood random-effect meta-analyses and meta-regression to explore potential moderators of treatment effect including methodologic study features (risk of bias domains and control group response rate), characteristics of the population, and intervention features following the theme, intensity, and platform framework. Results We included 199 PTSD trials that reported the outcomes of diagnosis resolution (122 trials, 8437 patients) and clinically meaningful improvement (133 trials, 9895 patients). Multiple treatments demonstrated effectiveness but with significant heterogeneity. Statistically significant moderators included risk of bias domains of randomization sequence and outcome measurement, control group response rate reflecting severity of PTSD in the enrolled population, and whether the psychotherapeutic approach was trauma focused (P values <0.05). There was no statistically significant effect for the frequency of treatments per week, format of the intervention (eg, individual vs group), duration of the intervention, or delivery method (in person vs not), (P values <0.05). Characteristics of the population such as sex, age, and military status did not appear to significantly affect the treatment effect (P values <0.05). Conclusion Trauma focused psychotherapies should be considered the first-line intervention to induce remission. Several patient characteristics or treatment context did not modify the treatment effect, which allows tailoring care based on patient values, preferences and logistics.

Abstract
OBJECTIVE This study examines treatment effects in STAIR Narrative Therapy (SNT), a phase-based treatment where Skills Training in Affective and Interpersonal Regulation (STAIR) precedes Narrative Therapy (NT), compared to Prolonged Exposure (PE) and to STAIR. METHOD Ninety-two adult patients diagnosed with DSM-5 PTSD and ICD-11 CPTSD following childhood abuse were randomly assigned to enhanced versions of SNT (12 group STAIR sessions + 8 individual NT sessions), PE (8-16 individual sessions), or STAIR (12 group STAIR sessions) provided in residential care. Outcome was assessed by mixed models. RESULTS PE produced greater improvements in DSM-5 PTSD symptoms compared to SNT from pre-treatment to post-treatment, but not compared to STAIR. Reductions in ICD-11 CPTSD symptoms were not significantly different among conditions. From pre-treatment to 1 year follow-up, PE produced greater PTSD symptom improvements than SNT and STAIR, and PE and STAIR produced greater CPTSD symptom improvements than SNT. CONCLUSIONS The predicted stronger effect of SNT compared to PE and STAIR on DSM-5 PTSD and ICD-11 CPTSD symptoms was not supported by the findings. The benefits of immediate trauma-focused treatments (TFT) as compared to phase-based treatments, and the potential non-inferiority of skills-training as compared to TFT in CPTSD needs to be further investigated.

Abstract
The Dissociative Symptoms Scale (DSS) was developed to assess moderately severe types of dissociation (depersonalization, derealization, gaps in awareness and memory, and dissociative reexperiencing) that would be relevant to a range of clinical populations, including those experiencing trauma-related dissociation. The current study used data from 10 ethnically and racially diverse clinical and community samples (N = 3,879) to develop a brief version of the DSS (DSS-B). Item information curves were examined to identify items with the most precision in measuring above average levels of the latent trait within each subscale. Analyses revealed that the DSS-B preserved the factor structure and content domains of the full scale, and its scores had strong reliability and validity that were comparable to those of scores on the full measure. DSS-B scores showed high levels of measurement invariance across ethnoracial groups. Results indicate that DSS-B scores are reliable and valid in the populations studied.

Abstract
Background: The fifth version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) introduced the dissociative subtype of posttraumatic stress disorder (D-PTSD). To assess this subtype, the Dissociative Subtype of PTSD Scale (DSPS), a 15-item self-report measure to identify lifetime and current dissociative symptoms of D-PTSD, was developed. However, so far, the scale has only been validated in war veterans. Moreover, criterion validity and diagnostic utility have not been examined yet.Objective: We aimed to validate the DSPS in two samples of civilian trauma-exposed German-speaking participants.Methods: In Study 1, a pre-registered online study, participants with and without PTSD symptoms (N = 558) answered questionnaires about traumatic experiences, dissociation, PTSD, depression, generalized anxiety disorder, somatic symptom disorder, alcohol use disorder, absorption, and dissociative responding to trauma-related questionnaires. In Study 2, which used secondary data of a pre-registered clinical study, participants with a PTSD diagnosis (N = 71) answered questionnaires about traumatic experiences, dissociation, PTSD, depression, generalized anxiety disorder, somatic symptom disorder, and dissociative responding to standardized trauma exposure. Moreover, PTSD, D-PTSD, and other diagnoses were assessed with structured clinical interviews.Results: Analyses confirmed a three-factor structure as well as high internal consistency, and high convergent, discriminant, and criterion validity of the DSPS. Moreover, the scale was able to identify a latent D-PTSD group and individuals with D-PTSD diagnosis.Conclusions: The DSPS constitutes a reliable and valid tool to assess D-PTSD symptoms in clinical practice and research and thereby may contribute to a better understanding of these debilitating symptoms.

Abstract
This study aimed to examine prevalence, clinical symptoms, and psychological characteristics of D-PTSD in a sample of Chinese prisoners with probable PTSD. A total of 1458 male prisoners were recruited from a large prison in Guangdong, China. Participants completed self-administrated questionnaires that assessed PTSD and dissociative symptoms, psychopathology, emotion regulation, emotional expressivity, social pleasure, traumatic events, and social support. According to DSM-5 criteria, participants were classified into four groups: D-PTSD, PTSD only, derealization/depersonalization (DD) only, and neither. The proportions of D-PTSD, PTSD only, DD only and neither were 2.5%, 4.7%, 2.4%, and 92.2%, respectively. PTSD symptoms and emotion regulation difficulties were distinguishing for the four groups: PTSD symptoms declined gradually in the order of D-PTSD, PTSD only, DD only, and neither, while emotion regulation difficulties declined in an order from D-PTSD, DD only, and PTSD only to neither, all ps < .001. D-PTSD and DD only had higher depressive and dissociative symptoms than PTSD only and the neither groups, all ps < .001. D-PTSD also had more borderline personality symptoms, emotion regulation difficulties, and more negative emotional expressivity than PTSD only and DD only, all ps < .05. Logistic regressions indicated that D-PTSD reported lower social support compared to PTSD only (OR = 0.95, p < .01), DD only (OR = 0.96, p < .05) and neither (OR = 0.93, p < .001). D-PTSD is common in probable PTSD in prisoners and is associated with complex clinical presentations as well as emotional processing. Social support is an important protective factor of D-PTSD.

Abstract
BACKGROUND A dissociative subtype of posttraumatic stress disorder, known as "D-PTSD", has been included in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. In addition to meeting criteria for PTSD, patients endorse prominent dissociative symptoms, namely depersonalization and derealization, or detachment from one's self and surroundings. At present, this population is supported by a highly heterogeneous and undeveloped literature. Targeted interventions are therefore lacking, and those indicated for PTSD are limited by poor efficacy, delayed onset of action, and low patient engagement. Here, we introduce cannabis-assisted psychotherapy (CAP) as a novel treatment for D-PTSD, drawing parallels to psychedelic therapy. CASE PRESENTATION A 28-year-old female presented with complex D-PTSD. In a naturalistic setting, she underwent 10 sessions of CAP, scheduled twice monthly over 5 months, coupled with integrative cognitive behavioral therapy. An autonomic and relational approach to CAP was leveraged, specifically psychedelic somatic interactional psychotherapy. Acute effects included oceanic boundlessness, ego dissolution, and emotional breakthrough. From baseline to post-treatment, the patient showed a 98.5% reduction in pathological dissociation, as measured by the Multidimensional Inventory of Dissociation, no longer meeting criteria for D-PTSD. This was accompanied by decreased cognitive distractibility and emotional suffering, as well as increased psychosocial functioning. Anecdotally, the patient has sustained improvements for over 2 years to date. CONCLUSIONS There is urgency to identify treatments for D-PTSD. The present case, while inherently limited, underscores the potential of CAP as a therapeutic option, leading to robust and sustained improvement. Subjective effects were comparable to those produced by classic and non-classic psychedelics, such as psilocybin and ketamine. Further research is warranted to explore, establish, and optimize CAP in D-PTSD, and to characterize its role in the pharmacological landscape.

Abstract
The Clinician-Administered Dissociative States Scale (CADSS) is a structured clinical interview to assess state dissociation rated by clinicians. The current study aimed to validate the German version of CADSS by comparing it to the established self-report measures for dissociation and exploring its underlying factor structure. Severity of within-session state dissociation was assessed directly following a standard psychotherapy session in a trauma-exposed patient sample (N= 105; 81.9% female). Internal consistency, convergent validity with other dissociation measures, and the factorial structure of the instrument were analyzed. The German version exhibited excellent internal consistency (Cronbach's α = .94) and correlated significantly with self-report measures of state dissociation (r = .86) and trait dissociation (r = .77) indicative of high convergent validity. Exploratory factor analysis revealed a three-factor solution with the factors (1) Depersonalization/Derealization, (2) Identity Confusion/Alteration, and (3) Amnesia. Results support the CADSS as a useful instrument to assess state dissociation, conceptualized as a multidimensional construct, in clinical practice.

Abstract
The dissociative subtype of post-traumatic stress disorder (PTSD-DS) was introduced in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), and is characterised by symptoms of either depersonalisation or derealisation, in addition to a diagnosis of post-traumatic stress disorder (PTSD). This systematic review and meta-analysis sought to estimate the point prevalence of current PTSD-DS, and the extent to which method of assessment, demographic and trauma variables moderate this estimate, across different methods of prevalence estimation. Studies included were identified by searching MEDLINE (EBSCO), PsycInfo, CINAHL, Academic Search Complete and PTSDpubs, yielding 49 studies that met the inclusion criteria (N = 8214 participants). A random-effects meta-analysis estimated the prevalence of PTSD-DS as 38.1% (95% CI 31.5-45.0%) across all samples, 45.5% (95% CI 37.7-53.4%) across all diagnosis-based and clinical cut-off samples, 22.8% (95% CI 14.8-32.0%) across all latent class analysis (LCA) and latent profile analysis (LPA) samples and 48.1% (95% CI 35.0-61.3%) across samples which strictly used the DSM-5 PTSD criteria; all as a proportion of those already with a diagnosis of PTSD. All results were characterised by high levels of heterogeneity, limiting generalisability. Moderator analyses mostly failed to identify sources of heterogeneity. PTSD-DS was more prevalent in children compared to adults, and in diagnosis-based and clinical cut-off samples compared to LCA and LPA samples. Risk of bias was not significantly related to prevalence estimates. The implications of these results are discussed further.

Abstract
INTRODUCTION Adults who have histories of childhood trauma have been noted to display greater somatization, dissociative symptoms and affect dysregulation. What happens in the parent-child relationship when those traumatized children become parents? A potential link to somatization in the child has been suggested by several prior studies. Children who have early attachment disturbances had more physical complaints if their mothers displayed less maternal sensitivity during observed parent-child interactions. Yet, the intergenerational link between maternal and child somatization has not been sufficiently explored in a longitudinal study in order to understand the potential impact of maternal trauma history and related psychopathology on subsequent child somatization and psychopathology. METHODS This paper examined prospective, longitudinal data of 64 mother-toddler dyads (mean age = 2.4 years, SD = 0.7) who were later studied when children had a mean age of 7 years. Mothers with and without histories of interpersonal violence (IPV; physical/sexual abuse and/or family violence exposure) were included. Mothers with IPV histories were oversampled. Linear and Poisson regression models were used to test the associations between maternal IPV-related post-traumatic stress disorder (PTSD) with maternal somatization severity when children were toddlers, and between maternal somatization and maternal interactive behaviors with child somatization by maternal report and clinician-rated assessment at school-age. RESULTS Maternal PTSD severity was significantly associated with increased maternal somatization severity (p = 0.031). Maternal somatization severity during the child's early childhood predicted both maternal report of child somatization (p = 0.011) as well as child thought problems (p = 0.007) when children were school-aged. No association was found between maternal somatization and child-reported psychopathology. The study did not find that maternal alexithymia, caregiving behaviors or child exposure to violence contributed significantly to the model examining the association between maternal and child somatization. CONCLUSION The results are in line with the hypothesis of intergenerational transmission of somatization in the context of IPV and related maternal PTSD during formative early development. We interpret this as an expression of psychological distress from mother to child, as maternal trauma and pathology affect the caregiving environment and, thus, the parent-child relationship. The authors conclude with a discussion of implications for parent-infant and early childhood intervention.

Personalization of Treatment for Patients with Childhood-Abuse-Related Posttraumatic Stress Disorder. J Clin Med 2021; 10:jcm10194522.

Abstract
Background: Differences in effectiveness among treatments for posttraumatic stress disorder (PTSD) are typically small. Given the variation between patients in treatment response, personalization offers a new way to improve treatment outcomes. The aim of this study was to identify predictors of psychotherapy outcome in PTSD and to combine these into a personalized advantage index (PAI). Methods: We used data from a recent randomized controlled trial comparing prolonged exposure (PE; n = 48), intensified PE (iPE; n = 51), and skills training (STAIR), followed by PE (n = 50) in 149 patients with childhood-abuse-related PTSD (CA-PTSD). Outcome measures were clinician-assessed and self-reported PTSD symptoms. Predictors were identified in the exposure therapies (PE and iPE) and STAIR+PE separately using random forests and subsequent bootstrap procedures. Next, these predictors were used to calculate PAI and to retrospectively determine optimal and suboptimal treatment in a leave-one-out cross-validation approach. Results: More depressive symptoms, less social support, more axis-1 diagnoses, and higher severity of childhood sexual abuse were predictors of worse treatment outcomes in PE and iPE. More emotion regulation difficulties, lower general health status, and higher baseline PTSD symptoms were predictors of worse treatment outcomes in STAIR+PE. Randomization to optimal treatment based on these predictors resulted in more improvement than suboptimal treatment in clinician assessed (Cohens’ d = 0.55) and self-reported PTSD symptoms (Cohens’ d = 0.47). Conclusion: Personalization based on PAI is a promising tool to improve therapy outcomes in patients with CA-PTSD. Further studies are needed to replicate findings in prospective studies.

Abstract
BACKGROUND Most people who experience a potentially traumatic event (PTE) recover on their own. A small group of individuals develops psychological complaints, but this is often not detected in time or guidance to care is suboptimal. To identify these individuals and encourage them to seek help, a web-based self-help test called Mobile Insight in Risk, Resilience, and Online Referral (MIRROR) was developed. MIRROR takes an innovative approach since it integrates both negative and positive outcomes of PTEs and time since the event and provides direct feedback to the user. OBJECTIVE The goal of this study was to assess MIRROR's use, examine its psychometric properties (factor structure, internal consistency, and convergent and divergent validity), and evaluate how well it classifies respondents into different outcome categories compared with reference measures. METHODS MIRROR was embedded in the website of Victim Support Netherlands so visitors could use it. We compared MIRROR's outcomes to reference measures of PTSD symptoms (PTSD Checklist for DSM-5), depression, anxiety, stress (Depression Anxiety Stress Scale-21), psychological resilience (Resilience Evaluation Scale), and positive mental health (Mental Health Continuum Short Form). RESULTS In 6 months, 1112 respondents completed MIRROR, of whom 663 also completed the reference measures. Results showed good internal consistency (interitem correlations range .24 to .55, corrected item-total correlations range .30 to .54, and Cronbach alpha coefficient range .62 to .68), and convergent and divergent validity (Pearson correlations range -.259 to .665). Exploratory and confirmatory factor analyses (EFA+CFA) yielded a 2-factor model with good model fit (CFA model fit indices: χ219=107.8, P<.001, CFI=.965, TLI=.948, RMSEA=.065), conceptual meaning, and parsimony. MIRROR correctly classified respondents into different outcome categories compared with the reference measures. CONCLUSIONS MIRROR is a valid and reliable self-help test to identify negative (PTSD complaints) and positive outcomes (psychosocial functioning and resilience) of PTEs. MIRROR is an easily accessible online tool that can help people who have experienced a PTE to timely identify psychological complaints and find appropriate support, a tool that might be highly needed in times like the coronavirus pandemic.

Abstract
If childhood trauma leads to dissociation, then this coping mechanism is powered by the imagination, creativity, consciousness, and similar areas of cognitive function. The goal of this article is to promote the treatment of trauma with particular emphasis on humanistic psychotherapy and behavioral therapy, such as “Play Therapy” for pediatric populations. It will thoroughly describe the multiple personality states within dissociative identity disorder, including the individualized sense of “self.” The diagnostic criteria of this mental disorder will be covered, along with assessment techniques that evoke a deeper understanding of dissociative disorders. It will also discuss comorbidities that present with dissociative disorders, such as posttraumatic stress disorder. This scholarly article suggests that dissociative disorders may result from experiencing tragic events and therefore need treatment for trauma to relieve negative symptoms of dissociation. The multidimensional aspects of dissociation are emphasized in their relation to the treatment of trauma.
