- Abstract
The Clinician-Administered PTSD Scale (CAPS) is a widely used diagnostic interview for posttraumatic stress disorder (PTSD). Following fundamental modifications in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), the CAPS had to be revised. This study examined the psychometric properties (internal consistency, interrater reliability, convergent and discriminant validity, and structural validity) of the German version of the CAPS-5 in a trauma-exposed sample (n = 223 with PTSD; n =51 without PTSD). The results demonstrated high internal consistency (αs =.65-.93) and high interrater reliability (ICCs =.81-.89). With regard to convergent and discriminant validity, we found high correlations between the CAPS severity score and both the Posttraumatic Diagnostic Scale sum score (r =.87) and the Beck Depression Inventory total score (r =.72). Regarding the underlying factor structure, the hybrid model demonstrated the best fit, followed by the anhedonia model. However, we encountered some nonpositive estimates for the correlations of the latent variables (factors) for both models. The model with the best fit without methodological problems was the externalizing behaviors model, but the results also supported the DSM-5 model. Overall, the results demonstrate that the German version of the CAPS-5 is a psychometrically sound measure.

- Abstract
PURPOSE: The Alaska Mountain Wilderness Ski Classic (AMWSC) is considered to be one of the most challenging ultra-endurance events in the world. The event has endured for more than 2 decades and various courses have traversed the Wrangell St. Elias, Chugach, Brooks and Alaska mountain ranges. There are no food drops, rest stations, or marked trails as skiers are free to pick the best route (ie., 100-150 miles) through the mountainous and remote Alaskan backcountry. Given the combined challenges of chronic activity, mental stress and cold exposure on physiological resilience, the purpose of this study was to evaluate the influence of the 2016 AMWSC that was staged in the Brooks Range (northernmost mountain range in North America) on energy expenditure and body composition. A two-tailed paired t-test was used to compare pre- and post-event alterations in lean body mass, fat mass and bone mineral density. METHODS: Fifteen male and female participants (mean±SEM; Age = 31.4±0.7, BMI = 23.7±0.6) were recruited for the study. Lean body mass, total fat mass, visceral fat mass and bone mineral density were measured using a General Electric iDXA pre- and post-event. In order to estimate total and daily energy expenditure, all participants wore a Actigraph wGT3X-BT monitor throughout the event. RESULTS: The first finishing group completed the event in 100 hours and 25 min, and the last individual completed the event at 121 hours and 7 min setting a course record for the closest time range within the finishing groups. Lean body mass and the relative skeletal muscle index (RSMI) increased by 1.7±0.3 kg and 0.22±0.05 kg/m2, respectively. While there was a significant reduction (-1.3±0.2 kg) in total fat mass, there was no change in bone mineral density (0.0044±0.0085 g/cm3). Including a correction for pack weight, daily energy expenditure was 5084±244, 7314±332, 7492±422, 7505±307, 6538±376, 3843±592, 5889±859 kcal, respectively over the course of the event.

Overgeneralization (i.e., the transfer of fear to stimuli not related to an aversive event) is part of alterations in associative fear learning in mental disorders. In the present experimental study, we investigated whether this holds true for post‐traumatic stress disorder (PTSD) related to childhood abuse. We expected that fear generalization under experimental conditions reflects generalization of aversive stimuli to different social domains in real life. Sixty‐four women with PTSD after childhood abuse and 30 healthy participants (HC) underwent a differential fear conditioning and generalization paradigm. Online risk ratings, reaction time, and fear‐potentiated startle served as dependent variables. Based on the subjectively assessed generalization of triggered intrusions across different domains of life, PTSD participants were split into two groups reporting low (low‐GEN) and high (high‐GEN) generalization. PTSD patients reported a higher expectation of an aversive event. During fear conditioning, they assessed the risk of danger related to a safety cue slower and showed a blunted fear‐potentiated startle toward the danger cue. During generalization testing, reaction time increased in the high‐GEN patients and decreased in the HC group with increasing similarity of a stimulus with the conditioned safety cue. Alterations of fear learning in PTSD suggest impaired defensive responses in case of a high threat probability. Moreover, our findings bridge the gap between the generalization of aversive cues during everyday life and laboratory‐based experimental parameters: impairments in the processing of cues signaling safety generalize particularly in those patients who report a spreading of PTSD symptoms across different domains of everyday life. Up to 75% of individuals who experienced physical and sexual abuse during childhood develop a post‐traumatic stress disorder (PTSD). The present experimental study contributes to the understanding of this disorder by revealing a complex picture of impairments in cognitive and emotional fear learning. A blunted fear‐potentiated startle revealed impaired defensive responses linked to the intensity and frequency of avoidance symptoms. Moreover, this is the first study that links overgeneralization of fear under experimental conditions to overgeneralization of aversive stimuli to different social domains in PTSD patients' real life.

- Abstract
Background: Since 2017 physicians in Germany can prescribe cannabis based medicines or medical cannabis with subsequent funding by the statutory health insurance system., Methods: Physicians prescribing cannabinoid drugs were legally required to take part in a survey conducted by the Federal Institute for Drugs and Medical Devices. This study analyses data from 16.809 case reports that were collected from 30.3.2017 to 31.12.2021., Results: There were 5582 cases documenting the use of cannabinoid drugs in psychiatric disorders. More than half of the prescriptions were Dronabinol. 80% of the treatments concerned somatoform disorders. Most of the treatments for other psychiatric disorders also targeted pain. Doctors reported a positive effect on symptoms in at least 75% of the cases., Discussion: Most patients with psychiatric disorders received cannabinoid drugs for pain. The evidence from randomized controlled clinical trials for the use of cannabinoid drugs in psychiatric indications is weak., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

- Abstract
Sleep disturbances are common in individuals with posttraumatic stress disorder. Exercise interventions are a promising approach in the treatment of sleep disorders, but little is known about the efficacy of exercise interventions for sleep disturbances associated with posttraumatic stress disorder. A total of 40 individuals with posttraumatic stress disorder were randomized to six sessions of either high-intensity interval training or low-to-moderate-intensity training, administered within 12 days. Sleep quality was assessed over 24 days from baseline to post with the Pittsburgh Sleep Quality Index, a sleep log, and a waist-worn actigraphy. Analyses revealed that, regardless of group allocation, Pittsburgh Sleep Quality Index score improved significantly by 2.28 points for high-intensity interval training and 1.70 points for low-to-moderate-intensity training (d = 0.56 for high-intensity interval training; 0.49 for low-to-moderate-intensity training) over time, while there were no significant changes in any sleep log or actigraphy measure. Analysis of a subsample of those affected by clinically significant sleep disturbances (n = 24) revealed a significant time effect with no difference between exercise interventions: Pittsburgh Sleep Quality Index improved significantly by 2.65 points for high-intensity interval training and 2.89 points for low-to-moderate-intensity training (d = 0.53 for high-intensity interval training; 0.88 for low-to-moderate-intensity training), and actigraphy measure of wake after sleep onset was reduced significantly by 14.39 minutes for high-intensity interval training and 6.96 minutes for low-to-moderate-intensity training (d = 0.47 for high-intensity interval training; 0.11 for low-to-moderate-intensity training) from baseline to post. In our pilot study, we found an improvement in sleep quality from pre- to post-assessment. There were no significant differences between exercise groups. Further studies are needed to investigate whether the found time effects reflect the exercise intervention or unrelated factors., (© 2024 The Author(s).

- Abstract
Objective: Patients with posttraumatic stress disorder (PTSD) report changes in what they think of the world and themselves, referred to as posttraumatic cognitions, and changes in how they think, reflected in increased perseverative thinking. We investigated whether pre-post therapy changes in the two aspects of thinking were associated with pre-post therapy changes in posttraumatic symptom severity., Method: 219 d clinic patients with posttraumatic stress symptoms received trauma-focused psychotherapy with cognitive behavioral and metacognitive elements. The posttraumatic cognitions inventory (PTCI), the perseverative thinking questionnaire (PTQ), and the Davidson trauma scale (DTS) were applied at two occasions, pre- and post-therapy. Using latent change score models, we investigated whether change in PTCI and change in PTQ were associated with change in DTS and its subscales. We then compared the predictive value of PTQ and PTCI in joint models., Results: When jointly modeled, change in overall DTS score was associated with change in both PTCI and PTQ. Concerning DTS subscales, reexperiencing and avoidance were significantly associated with change in PTCI, but not in PTQ., Conclusion: Results indicate that both aspects of cognition may be valuable targets of psychotherapy. A focus on posttraumatic cognitions might be called for in patients with severe reexperiencing and avoidance.

- Abstract
Background: Posttraumatic stress disorder (PTSD) is often associated with female sexual dysfunctions (FSD). However, little is known about the impact of therapies for PTSD on FSD according to DSM-5 criteria., Aim/objective: To examine if sexual functioning diagnosed according to DSM-5 criteria improves after treatment for PTSD in women with a PTSD diagnosis after interpersonal child abuse., Method: FSD according to DSM-5 criteria were assessed with the structured clinical interview SISEX in N = 152 female participants (mean age = 36.5 years) of a large randomized controlled trial three months into treatment and after 15 months of receiving either dialectical behavior therapy for PTSD or cognitive processing therapy. Number of fulfilled FSD criteria and diagnostic status were compared from pre-to post-treatment using Poisson and negative binomial regression analyses and the McNemar test. The effect of treatment type on reduction of FSD symptoms and the association between reduction in PTSD symptoms and reduction in FSD symptoms were assessed., Results: From pre-to post-treatment, the number of fulfilled criteria for each FSD decreased (Incident rate ratios between 0.60 and 0.71, p between <. 001 and <0 .05). Less women met criteria for genito-pelvic pain/penetration disorder at post-treatment compared to pre-treatment (11.8 % vs. 6.6 %, p < .05). No difference was found between treatments in reduction of FSD symptoms. Reduction of PTSD symptoms was associated with greater decrease in FSD symptoms., Conclusions: Our results suggest a positive association between effective PTSD treatments and improvements in sexual functioning of women with PTSD after child abuse., Competing Interests: Declaration of competing interest Regina Steil, Kathlen Priebe, and Meike Müller-Engelmann receive honoraries for workshops and talks on DBT-PTSD and CPT., (Copyright © 2024 Elsevier Ltd.

- Abstract
Background: The complexity of posttraumatic stress disorder (PTSD) symptoms related to childhood abuse (CA) present challenges for effective psychotherapeutic treatment. Consequently, there is great interest in the long-term effectiveness of psychological treatments for this population. Objective: This study aims to investigate the long-term outcomes of Dialectical Behaviour Therapy for PTSD (DBT-PTSD) and Cognitive Processing Therapy (CPT) 9 months after treatment termination. Method: This is a long-term analysis from a randomised-controlled trial of DBT-PTSD versus CPT (registration number DRKS00005578). Initially, 193 individuals with CA-related PTSD were randomly allocated to receive either DBT-PTSD ( n = 98) or CPT ( n = 95). The primary outcome the Clinician-administered PTSD-Scale for DSM-5 (CAPS-5) was administred at baseline, treatment completion (15 months post-randomization) and at the 9-month follow-up. Secondary outcomes included self-reported PTSD severity (PCL-5), dissociation (DSS), severity of borderline symptoms (BSL-23), and psychosocial functioning (GAF). Results: No significant changes were observed in the primary (CAPS) and all other outcomes from post-intervention to 9-months follow-up in both the DBT-PTSD (CAPS: M
post = 15.60, Mfollow-up = 14.93) and CPT group (CAPS: Mpost = 18.80, Mfollow-up = 17.41). Between-group analyses at 9-months follow-up were significantly in favour of DBT-PTSD compared to CPT with small to medium effect sizes on all outcomes ranging from d = 0.35 on the CAPS to d = 0.57 on the BSL-23 and GAF. Conclusions: Our results indicate that treatment effects of psychotherapy addressing complex presentations of PTSD persist 9 months after treatment termination. In addition, the superiority of DBT-PTSD as compared to CPT found at treatment termination, was confirmed at 9-months follow-up.

- Abstract
Background: With the introduction of the ICD-11 into clinical practice, the reliable distinction between Posttraumatic Stress Disorder (PTSD) and Complex Posttraumatic Stress Disorder (CPTSD) becomes paramount. The semi-structured clinician-administered International Trauma Interview (ITI) aims to close this gap in clinical and research settings. Objective: This study investigated the psychometric properties of the German version of the ITI among trauma-exposed clinical samples from Switzerland and Germany. Method: Participants were 143 civilian and 100 military participants, aged M = 40.3 years, of whom 53.5% were male. Indicators of reliability and validity (latent structure, internal reliability, inter-rater agreement, convergent and discriminant validity) were evaluated. Confirmatory factor analysis (CFA) and partial correlation analysis were conducted separately for civilian and military participants. Results: Prevalence of PTSD was 30% (civilian) and 33% (military) and prevalence of CPTSD was 53% (civilians) and 21% (military). Satisfactory internal consistency and inter-rater agreement were found. In the military sample, a parsimonious first-order six-factor model was preferred over a second-order two-factor CFA model of ITI PTSD and Disturbances in Self-Organization (DSO). Model fit was excellent among military participants but no solution was supported among civilian participants. Overall, convergent validity was supported by positive correlations of ITI PTSD and DSO with DSM-5 PTSD. Discriminant validity for PTSD symptoms was confirmed among civilians but low in the military sample. Conclusions: The German ITI has shown potential as a clinician-administered diagnostic tool for assessing ICD-11 PTSD and CPTSD in primary care. However, further exploration of its latent structure and discriminant validity are indicated.

- Abstract
Background and Objectives: The Affect Intolerance Scale (AIS) assesses two core concepts of emotion regulation: appraisals of negative emotions as threatening and proneness to emotional avoidance. Maladaptive emotion regulation is associated with various psychopathologies. We translated and validated the AIS in a German student and clinical sample of patients with trauma-related disorders., Methods: 340 patients, 161 with post-traumatic stress disorder and 179 with adjustment disorder, and 322 students were enrolled. We employed exploratory and confirmatory factor analyses in a cross-validation design to investigate construct validity, convergent and discriminant validity, and reliability., Results: We replicated the originally described two-factor structure in both samples. Cronbach's α was 0.947 in the student and 0.950 in the clinical sample. AIS subscales showed moderate to high correlations with convergent and low correlations with discriminant measures. AIS total scores were significantly larger in the clinical sample, controlled for gender and age., Limitations: This study provides a unified cross-validation model in a clinical and a student sample at the cost of reduced sample sizes., Conclusions: The AIS is a valid measure of affect intolerance with the discriminative ability to distinguish between patients with trauma-related disorders and students. Test redundancy within both sub-constructs of the AIS might lead to biased estimates but allows for increased test precision, rendering the AIS a tool suitable for individual treatment monitoring., Competing Interests: Declaration of competing interest The authors declare that there is no conflict of interest. No funding was received to assist with the preparation of this manuscript., (Copyright © 2023 Elsevier Ltd. All rights reserved.)

- Abstract
Many women with posttraumatic stress disorder (PTSD) after child sexual abuse (CSA) suffer from sexual problems. However, little is known about the frequency of female sexual dysfunctions (FSD) as defined by DSM-5 among women with PTSD due to CSA. Furthermore, factors related to FSD in this patient population are understudied. To assess prevalence rates and clinical correlates of FSD according to DSM-5 criteria in women with PTSD after CSA, a structured clinical interview for sexual dysfunctions according to DSM-5 criteria was administered in a sample of 137 women with PTSD after CSA. Participants also completed measures for PTSD, depression symptoms, and borderline personality disorder symptoms. The association between FSD, severity of abuse, PTSD-, depression-, borderline symptom severity, and age was examined. In a second step, the association between FSD and PTSD-clusters was assessed. Diagnostic criteria of female sexual interest/arousal disorder (FSIAD) were met by 2.6% of women in our sample. 5.2% met criteria of female orgasmic disorder (FOD), and 11.8% those of genito-pelvic pain/penetration disorder (GPPPD). PTSD symptom severity predicted number of fulfilled criteria of FSIAD and FOD, the cluster "negative alterations in cognition and mood," was associated with more fulfilled criteria in FSIAD and FOD. The majority of women reported sexual problems, but diagnostic criteria of FSD were met by only a small number of participants. PTSD symptoms, especially the cluster "negative alterations in cognition and mood," seem to be related to female sexual functioning after CSA., (© 2023. The Author(s).)

- Abstract
Background: Distressing nightmares are a core symptom of posttraumatic stress disorder (PTSD) and contribute to psychiatric comorbidity, impaired physical health and decreased social functioning. No specific pharmacological treatment for PTSD-related nightmares is yet approved. Preliminary clinical data indicate that cannabinoid agonists can improve nightmares and overall PTSD symptoms in patients with PTSD. The primary objective of the study is to examine the efficacy of oral dronabinol (BX-1) versus placebo in reducing nightmares in patients with PTSD. The secondary objectives of the study are to examine the efficacy of oral BX-1 in reducing other PTSD symptoms., Methods: The study is designed as a multi-centric, double-blind, randomized (1:1), placebo-controlled, parallel group interventional trial. Eligible patients will be randomized to BX-1 or placebo, receiving a once-daily oral dose before bedtime for 10 weeks. Primary efficacy endpoint is the Clinician-Administered PTSD Scale (CAPS-IV) B2 score for the last week, measuring frequency and intensity of nightmares. Secondary efficacy endpoints are other disorder-specific symptoms in patients with PTSD. Further, tolerability and safety of dronabinol will be assessed., Discussion: This randomized controlled trial will provide evidence whether treating patients with PTSD and nightmares with dronabinol is safe and efficacious., Trial Registration: NCT04448808, EudraCT 2019-002211-25., (© 2023.

- Abstract
Background: Literature on the association between therapist adherence and treatment success in the treatment of post-traumatic stress disorder (PTSD) is scarce, and the results are mixed. Objective: To examine the relationship between therapist adherence to dialectical behaviour therapy for PTSD (DBT-PTSD) and cognitive processing therapy (CPT) on treatment outcome in women with PTSD and emotion regulation difficulties after interpersonal childhood abuse. Method: Videotaped therapy sessions from 160 female participants of a large randomized controlled trial [Bohus, M., Kleindienst, N., Hahn, C., Müller-Engelmann, M., Ludäscher, P., Steil, R., Fydrich, T., Kuehner, C., Resick, P. A., Stiglmayr, C., Schmahl, C., & Priebe, K. (2020). Dialectical behavior therapy for posttraumatic stress disorder (DBT-PTSD) compared with cognitive processing therapy (CPT) in complex presentations of PTSD in women survivors of childhood abuse. JAMA Psychiatry , 77 (12), 1235. jamapsychiatry.2020.2148] were rated. Adherence to CPT and DBT-PTSD was assessed using two specifically developed rating scales. Results: Higher therapist adherence was associated with a greater reduction of clinician-rated PTSD symptom severity. This effect was more pronounced in the CPT group than in the DBT-PTSD group. Adherence was also related to a greater reduction of self-rated PTSD symptoms, borderline symptoms, and dissociation intensity. Conclusion: Our results indicate that higher therapist adherence can lead to better treatment outcomes in PTSD treatments, especially in CPT.

- Abstract
Background: Literature on the association between therapist competence and treatment success in posttraumatic stress disorder (PTSD) treatments is scarce and results are mixed. Aims/Objective: The relationship between different types of therapeutic competence, therapeutic alliance, and PTSD symptom reduction in patients treated with Dialectical Behaviour Therapy for PTSD (DBT-PTSD) or Cognitive Processing Therapy (CPT) was assessed. Competence types were PTSD-specific competence, treatment specific competence, and general competence in cognitive behaviour therapy (CBT). Method: Videotaped therapy sessions from N = 160 women with PTSD and emotion regulation difficulties after child abuse participating in a large randomised controlled trial (Bohus et al., 2020) were rated. Three therapeutic competence-types were assessed using specifically developed rating scales. Alliance was assessed via patient ratings with the Helping Alliance Questionnaire (HAQ). PTSD symptoms were assessed at pre- and post-treatment via clinician rating with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and via self-rating with the PTSD-Checklist for DSM-5 (PCL-5). Results: No significant association between competence and clinician or self-rated PTSD symptoms was found. PTSD specific competence predicted clinician rated PTSD symptom severity on a trend level. Alliance predicted both clinician and self-rated PTSD symptom reduction. Conclusion: Our results provide a starting point for future research on different competence types and their association with PTSD treatment gains. Therapists were highly trained and received weekly supervision, hence a restricted competence range is a possible explanation for non-existing associations between competence and PTSD symptom reduction in our sample. More research in naturalistic settings, such as dissemination studies, is needed.

- Abstract
Objective: Posttraumatic stress disorder (PTSD) is associated with psychosocial impairments, which represent a relevant focus for therapy. Previous results on the clinical predictors of these psychosocial impairments were inconsistent. The data analyzed in these contexts often suffer from a high number of correlated predictors and small sample sizes, entailing the risk of model overfitting. In Bayesian regression, the problem of overfitting can be mitigated by usage of specific zero-centered (regularizing) prior distributions. In this study, we used the 2 most common Bayesian regression models, the Bayesian Ridge and the Bayesian Lasso, to predict psychosocial impairments in 192 patients of a day clinic for the treatment of PTSD., Method: Predictions were based on specific dimensions of PTSD symptoms previously revealed by factor analyses, as well as posttraumatic cognitions, depressive symptoms, comorbid disorders, and demographics. The variance of the prior distribution was estimated through empirical Bayes (maximum marginal likelihood) and an approximation to the posterior distribution was obtained with stochastic variational inference and with a local approximation (Laplace approximation)., Results: Severe psychosocial impairments were mainly related to depressive symptoms and symptoms from the amnesia and numbing dimension of PTSD, while gender, posttraumatic cognitions, and reexperience and avoidance symptoms had no impact. As expected, the model coefficients were shrunken to zero when regularizing prior distributions were used, particularly for the Bayesian Lasso., Conclusion: Depressive and numbing symptoms are the main clinical correlates of psychosocial impairments in patients with PTSD. Usage of Bayesian and regularized regression can contribute to the generalizability and interpretability of research results. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

- Abstract
Adverse experiences can lead to severe mental health problems, such as posttraumatic stress disorder (PTSD), throughout the lifespan. In individuals with PTSD, both global and local brain volume reductions have been reported-especially in the amygdala and hippocampus-while the literature on childhood maltreatment suggests a strong dependency on the timing of adverse events. In the present study, we pooled data from two studies to contrast the effects of reported trauma exposure during neurodevelopmentally sensitive periods in early life with trauma exposure during adulthood. A total of 155 women were allocated into one of six age-matched groups according to the timing of traumatization (childhood vs adulthood) and psychopathology (PTSD vs trauma-exposed healthy vs trauma-naïve healthy). Volumes of the amygdala and hippocampus were compared between these groups. Six additional exploratory regions of interest (ROI) were included based on a recent meta-analysis. Amygdala volume was strongly dependent on the timing of traumatization: Smaller amygdala volumes were observed in participants with childhood trauma and PTSD compared to the healthy control groups. In contrast, larger amygdala volumes were observed in both groups with trauma exposure during adulthood compared to the trauma-naïve control group. Hippocampal volume comparisons revealed no statistically significant differences, although the descriptive pattern was similar to that found for the amygdala. The remaining exploratory ROIs showed significant group effects, but no timing effects. The timing might be an important moderator for adversity effects on amygdala volume, potentially reflecting neurodevelopmental factors. Albeit confounded by characteristics like trauma type and multiplicity, these findings pertain to typical childhood and adulthood trauma as often observed in clinical practice and speak against a simple association between traumatic stress and amygdala volume., (© 2022.

- Abstract
Study Objectives: Subjective reports of sleep impairments are common in individuals with posttraumatic stress disorder (PTSD), but objective assessments of sleep have yielded mixed results., Methods: We investigated sleep via actigraphy and e-diary on 6 consecutive nights in a group of 117 women with PTSD after childhood abuse (CA; PTSD group), a group of 31 mentally healthy women with a history of CA (healthy trauma controls, HTC group) and a group of 36 nontraumatized mentally healthy women (healthy controls, HC group)., Results: The PTSD group reported lower sleep quality, more nights with nightmares, and shorter sleep duration than both HTC and HC. Actigraphic measures showed more and longer sleep interruptions in the PTSD group compared to HTC and HC, but no difference in sleep duration. While the PTSD group underestimated their sleep duration, both HTC and HC overestimated their sleep duration. HTC did not differ from HC regarding sleep impairments., Conclusions: Sleep in women with PTSD after CA seems to be more fragmented but not shorter compared to sleep patterns of mentally healthy control subjects. The results suggest a stronger effect of PTSD psychopathology on sleep compared to the effect of trauma per se., Subset of Data From Clinical Trial: Treating Psychosocial and Neural Consequences of Childhood Interpersonal Violence in Adults (RELEASE), https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00000000, German Clinical Trials registration number: DRKS00005578., (© The Author(s) 2021.

- Abstract
Objective: About half of individuals seeking treatment for borderline personality disorder (BPD) present with co-occurring posttraumatic stress disorder (PTSD). However, therapies that have been proven efficacious for simultaneously treating the full spectrum of core symptoms in patients with a dual diagnosis of BPD + PTSD are lacking., Method: This is a subgroup analysis from a randomized controlled trial (registration number DRKS00005578) which compared the efficacy of two treatment programs, dialectical behavior therapy for PTSD (DBT-PTSD) versus cognitive processing therapy (CPT). Specifically, the present analysis was carried out in 93 women with a dual diagnosis of BPD + PTSD (Diagnostic and Statistical Manual for Mental Disorders; DSM-5). Outcome evaluations included the Clinician-Administered PTSD Scale, the Borderline Symptom List, and validated scales assessing dissociation, depression, and global functioning. The primary analysis was based on the intent-to-treat population, using mixed models., Results: Both PTSD and BPD symptoms significantly decreased in both treatment groups. For PTSD symptoms, pre-post effect sizes were d = 1.20, 95% confidence interval (CI): [0.80-1.58] in the DBT-PTSD group and d = 0.90, 95% CI: [0.57-1.22] in the CPT group; for BPD symptoms, they were d = 1.17, 95% CI: [0.77-1.55], and d = 0.50, 95% CI: [0.20-0.79], respectively. Between-group comparisons significantly favored DBT-PTSD for improvement in symptoms of PTSD, BPD, and dissociation. Between-group differences regarding depression and global functioning were not significant., Conclusion: Both DBT-PTSD and CPT emerged as promising treatment options for simultaneously addressing the full spectrum of core symptoms in patients diagnosed with BPD + PTSD. Differential efficacy was in favor of DBT-PTSD as participants randomized to the DBT-PTSD arm improved more with respect to both their BPD and PTSD symptoms.

- Abstract
Background: Identifying predictors for treatment outcome in patients with posttraumatic stress disorder (PTSD) is important in order to provide an effective treatment, but robust and replicated treatment outcome predictors are not available up to now., Objectives: We investigated predictors of treatment outcome in a naturalistic sample of patients with PTSD admitted to an 8-week daycare cognitive behavioural therapy programme following a wide range of traumatic events., Method: We used machine learning (linear and non-linear regressors and cross-validation) to predict outcome at discharge for 116 patients and sustained treatment effects 6 months after discharge for 52 patients who had a follow-up assessment. Predictions were based on a wide selection of demographic and clinical assessments including age, gender, comorbid psychiatric disorders, trauma history, posttraumatic symptoms, posttraumatic cognitions, depressive symptoms, general psychopathology and psychosocial functioning., Results: We found that demographic and clinical variables significantly, but only modestly predicted PTSD treatment outcome at discharge (r = 0.21, p = .021 for the best model) and follow-up (r = 0.31, p = .026). Among the included variables, more severe posttraumatic cognitions were negatively associated with treatment outcome. Early response in PTSD symptomatology (percentage change of symptom scores after 4 weeks of treatment) allowed more accurate predictions of outcome at discharge (r = 0.56, p < .001) and follow-up (r = 0.43, p = .001)., Conclusion: Our results underscore the importance of early treatment response for short- and long-term treatment success. Nevertheless, it remains an unresolved challenge to identify variables that can robustly predict outcome before the initiation of treatment., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2021 The Author(s).

- Abstract
There is growing empirical evidence for an association between childhood abuse (CA) and intimate partner violence (IPV) in adulthood. We tested whether revictimized survivors of severe to extreme severities of child sexual abuse (CSA) and severe severities of child physical abuse (CPA) differed from nonvictimized healthy controls in their trait preferences in intimate partners and their current mate choice. In a sample of 52 revictimized female patients with posttraumatic stress disorder (PTSD) after CSA/CPA and 52 female healthy controls, the validated Intimate Partner Preferences Questionnaire (IPPQ) was used to assess (a) the desirability of tenderness, dominance, and aggression traits in potential partners, and (b) the presence of these traits in their current intimate partners. Factors potentially associated with partner preference and mate choice, for example, chronicity of traumatic events and lower self-esteem, were explored. Our results showed that, in general, revictimized PTSD patients did not have a preference for dominant or aggressive partners. However, revictimized women displayed a significantly larger discrepancy than did healthy controls between their preferences for tenderness traits and their ratings of the presence of tenderness traits in their current partners. Our results indicated that revictimized patients had lower self-esteem values; however, these values were associated with higher demands for tenderness traits. Furthermore, our results revealed that compared with patients who experienced early-onset childhood abuse (CA), those who experienced later onset CA were more accepting of dominant traits in potential partners. Women who had experienced IPV rated their current partners to be overly dominant. A higher tolerance of dominance traits might increase the risk of IPV in a specific subgroup of abused women (women with a later onset of abuse experiences and experiences of IPV).

- Abstract
Importance: Childhood abuse significantly increases the risk of developing posttraumatic stress disorder (PTSD), often accompanied by symptoms of borderline personality disorder (BPD) and other co-occurring mental disorders. Despite the high prevalence, systematic evaluations of evidence-based treatments for PTSD after childhood abuse are sparse., Objective: To compare the efficacy of dialectical behavior therapy for PTSD (DBT-PTSD), a new, specifically designed, phase-based treatment program, against that of cognitive processing therapy (CPT), one of the best empirically supported treatments for PTSD., Design, Setting, and Participants: From January 2014 to October 2016, women who sought treatment were included in a multicenter randomized clinical trial with blinded outcome assessments at 3 German university outpatient clinics. The participants were prospectively observed for 15 months. Women with childhood abuse-associated PTSD who additionally met 3 or more DSM-5 criteria for BPD, including affective instability, were included. Data analysis took place from October 2018 to December 2019., Interventions: Participants received equal dosages and frequencies of DBT-PTSD or CPT, up to 45 individual sessions within 1 year and 3 additional sessions during the following 3 months., Main Outcomes and Measures: The predefined primary outcome was the course of the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) score from randomization to month 15. Intent-to-treat analyses based on dimensional CAPS-5 scores were complemented by categorical outcome measures assessing symptomatic remission, reliable improvement, and reliable recovery., Results: Of 955 consecutive individuals assessed for eligibility, 193 were randomized (DBT-PTSD, 98; CPT, 95; mean [SD] age, 36.3 [11.1] years) and included in the intent-to-treat analyses. Analysis revealed significantly improved CAPS-5 scores in both groups (effect sizes: DBT-PTSD: d, 1.35; CPT: d, 0.98) and a small but statistically significant superiority of DBT-PTSD (group difference: 4.82 [95% CI, 0.67-8.96]; P = .02; d, 0.33). Compared with the CPT group, participants in the DBT-PTSD group were less likely to drop out early (37 [39.0%] vs 25 [25.5%]; P = .046) and had higher rates of symptomatic remission (35 [40.7%] vs 52 [58.4%]; P = .02), reliable improvement (53 [55.8%] vs 73 [74.5%]; P = .006), and reliable recovery (34 [38.6%] vs 52 [57.1%]; P = .01)., Conclusions and Relevance: These findings support the efficacy of DBT-PTSD and CPT in the treatment of women with childhood abuse-associated complex PTSD. Results pertaining to the primary outcomes favored DBT-PTSD. The study shows that even severe childhood abuse-associated PTSD with emotion dysregulation can be treated efficaciously., Trial Registration: German Clinical Trials Register: DRKS00005578.

- Abstract
The Clinician-Administered PTSD Scale (CAPS) is a widely used diagnostic interview for posttraumatic stress disorder (PTSD). Following fundamental modifications in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition ( DSM-5 ), the CAPS had to be revised. This study examined the psychometric properties (internal consistency, interrater reliability, convergent and discriminant validity, and structural validity) of the German version of the CAPS-5 in a trauma-exposed sample ( n = 223 with PTSD; n =51 without PTSD). The results demonstrated high internal consistency (αs = .65-.93) and high interrater reliability (ICCs = .81-.89). With regard to convergent and discriminant validity, we found high correlations between the CAPS severity score and both the Posttraumatic Diagnostic Scale sum score ( r = .87) and the Beck Depression Inventory total score ( r = .72). Regarding the underlying factor structure, the hybrid model demonstrated the best fit, followed by the anhedonia model. However, we encountered some nonpositive estimates for the correlations of the latent variables (factors) for both models. The model with the best fit without methodological problems was the externalizing behaviors model, but the results also supported the DSM-5 model. Overall, the results demonstrate that the German version of the CAPS-5 is a psychometrically sound measure.

- Abstract
Early experiences of childhood sexual or physical abuse are often associated with functional impairments, reduced well-being and interpersonal problems in adulthood. Prior studies have addressed whether the traumatic experience itself or adult psychopathology is linked to these limitations. To approach this question, individuals with posttraumatic stress disorder (PTSD) and healthy individuals with and without a history of child abuse were investigated. We used global positioning system (GPS) tracking to study temporal and spatial limitations in the participants' real-life activity space over the course of one week. The sample consisted of 228 female participants: 150 women with PTSD and emotional instability with a history of child abuse, 35 mentally healthy women with a history of child abuse (healthy trauma controls, HTC) and 43 mentally healthy women without any traumatic experiences in their past (healthy controls, HC). Both traumatized groups-i.e. the PTSD and the HTC group-had smaller movement radii than the HC group on the weekends, but neither spent significantly less time away from home than HC. Some differences between PTSD and HC in movement radius seem to be related to correlates of PTSD psychopathology, like depression and physical health. Yet group differences between HTC and HC in movement radius remained even when contextual and individual health variables were included in the model, indicating specific effects of traumatic experiences on activity space. Experiences of child abuse could limit activity space later in life, regardless of whether PTSD develops., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Deleterious effects of adverse childhood experiences (ACE) on human brain volume are widely reported. First evidence points to differential effects of ACE on brain volume in terms of timing of ACE. Upcoming studies additionally point towards the impact of different types (i.e., neglect and abuse) of ACE in terms of timing. The current study aimed to investigate the correlation between retrospectively reported severity of type (i.e., the extent to which subjects were exposed to abuse and/or neglect, respectively) and timing of ACE on female brain volume in a sample of prolonged traumatized subjects. A female sample with ACE (N = 68) underwent structural magnetic resonance imaging and a structured interview exploring the severity of ACE from age 3 up to 17 using the "Maltreatment and Abuse Chronology of Exposure" (MACE). Random forest regression with conditional interference trees was applied to assess the impact of ACE severity as well as the severity of ACE type, (i.e. to what extent individuals were exposed to neglect and/or abuse) at certain ages on pre-defined regions of interest such as the amygdala, hippocampus, and anterior cingulate (ACC) volume. Analyses revealed differential type and timing-specific effects of ACE on stress sensitive brain structures: Amygdala and hippocampal volume were affected by ACE severity during a period covering preadolescence and early adolescence. Crucially, this effect was driven by the severity of neglect.

- Abstract
Objective: Previous studies have found evidence of an attentional bias for trauma-related stimuli in posttraumatic stress disorder (PTSD) using eye-tracking (ET) technlogy. However, it is unclear whether findings for PTSD after traumatic events in adulthood can be transferred to PTSD after interpersonal trauma in childhood. The latter is often accompanied by more complex symptom features, including, for example, affective dysregulation and has not yet been studied using ET. The aim of this study was to explore which components of attention are biased in adult victims of childhood trauma with PTSD compared to those without PTSD., Method: Female participants with (n = 27) or without (n = 27) PTSD who had experienced interpersonal violence in childhood or adolescence watched different trauma-related stimuli (Experiment 1: words, Experiment 2: facial expressions). We analyzed whether trauma-related stimuli were primarily detected (vigilance bias) and/or dwelled on longer (maintenance bias) compared to stimuli of other emotional qualities., Results: For trauma-related words, there was evidence of a maintenance bias but not of a vigilance bias. For trauma-related facial expressions, there was no evidence of any bias., Conclusions: At present, an attentional bias to trauma-related stimuli cannot be considered as robust in PTSD following trauma in childhood compared to that of PTSD following trauma in adulthood. The findings are discussed with respect to difficulties attributing effects specifically to PTSD in this highly comorbid though understudied population.

- Abstract
Dialectical behavior therapy for posttraumatic stress disorder (DBT-PTSD) is a trauma-focused therapy shown to reduce core PTSD symptoms, such as intrusions, hyperarousal, and avoidance. Preliminary data indicate effects on elevated trauma-related emotions (e.g., guilt and shame) and possibly radical acceptance of the traumatic event. However, it is unclear if improvements in these variables are significant after controlling for changes in core PTSD symptoms and to what extent nonclinical levels are obtained. In the current study, 42 individuals who met criteria for PTSD after childhood abuse and were participating in a 3-month residential DBT-PTSD program were evaluated at the start of the exposure phase of DBT-PTSD and the end of treatment; a nonclinical sample with a history of childhood abuse was the reference group. Multivariate analyses of variance and multivariate analyses of covariance controlling for change in core PTSD symptoms were used to evaluate changes in several elevated trauma-related emotions (fear, anger, guilt, shame, disgust, sadness, and helplessness) and in radical acceptance. In a repeated measures multivariate analyses of variance, both elevated trauma-related emotions and radical acceptance significantly improved during DBT-PTSD, λ = 0.34, p < .001; η
2 = .56; t(40) = -5.66, p < .001, SMD = 0.88, even after controlling for changes in PTSD symptoms, λ = 0.35, p < .001, η2 = .65; Λ = 0.86, p = .018, η2 = .14, respectively. Posttreatment, 31.0% (for acceptance) to 76.2% (for guilt) of participants showed nonclinical levels of the investigated outcomes, suggesting that both trauma-related emotions and radical acceptance changed after the 3-month residential DBT-PTSD program., (© 2019 International Society for Traumatic Stress Studies.)- Published

- Abstract
Background: Posttraumatic stress disorder (PTSD) after childhood abuse (CA) is often related to severe co-occurring psychopathology, such as symptoms of borderline personality disorder (BPD). The ICD-11 has included Complex PTSD as a new diagnosis, which is defined by PTSD symptoms plus disturbances in emotion regulation, self-concept, and interpersonal relationships. Unfortunately, the empirical database on psychosocial treatments for survivors of CA is quite limited. Furthermore, the few existing studies often have either excluded subjects with self-harm behaviour and suicidal ideation - which is common behaviour in subjects suffering from Complex PTSD. Thus, researchers are still trying to identify efficacious treatment programmes for this group of patients.We have designed DBT-PTSD to meet the specific needs of patients with Complex PTSD. The treatment programme is based on the rules and principles of dialectical behavioural therapy (DBT), and adds interventions derived from cognitive behavioural therapy, acceptance and commitment therapy and compassion-focused therapy. DBT-PTSD can be provided as a comprehensive residential programme or as an outpatient programme. The effects of the residential programme were evaluated in a randomised controlled trial. Data revealed significant reduction of posttraumatic symptoms, with large between-group effect sizes when compared to a treatment-as-usual wait list condition (Cohen's d = 1.5).The first aim of this project on hand is to evaluate the efficacy of the outpatient DBT-PTSD programme. The second aim is to identify the major therapeutic variables mediating treatment efficacy. The third aim is to study neural mechanisms and treatment sensitivity of two frequent sequelae of PTSD after CA: intrusions and dissociation., Methods: To address these questions, we include female patients who experienced CA and who fulfil DSM-5 criteria for PTSD plus borderline features, including criteria for severe emotion dysregulation. The study is funded by the German Federal Ministry of Education and Research, and started in 2014. Participants are randomised to outpatient psychotherapy with either DBT-PTSD or Cognitive Processing Therapy. Formal power analysis revealed a minimum of 180 patients to be recruited. The primary outcome is the change on the Clinician-Administered PTSD Scale for DSM-5., Discussion: The expected results will be a major step forward in establishing empirically supported psychological treatments for survivors of CA suffering from Complex PTSD., Trial Registration: German Clinical Trials Register: registration number DRKS00005578, date of registration 19 December 2013., Competing Interests: This study approval was obtained from the independent Ethics Committee of the Medical Faculty Mannheim at Heidelberg University (Reference number: 2013–635 N-MA). The study was also approved by the ethics committee of Goethe-University and Humboldt University.Not applicable.On behalf of all the authors, the corresponding author states that he has no competing interests.Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

- Abstract
A neurocircuitry model of post-traumatic stress disorder (PTSD) suggests increased amygdala responses to emotional stimuli, coupled with hypoactivation of prefrontal regions associated with cognitive control. However, results are heterogenous across different subsamples of PTSD as well as different paradigms. We investigated cognitive control in a classic and emotional Stroop task in 28 female patients with complex PTSD (cPTSD), 28 female trauma-exposed healthy controls (TCs) and 28 female non-trauma-exposed healthy controls (HCs) using functional neuroimaging. Afterwards, we assessed memory function in a spontaneous free recall and recognition task. Patients with cPTSD displayed significantly greater Stroop interference with trauma-related words (as reflected in slower reaction times and increased errors) compared to the other conditions and compared to the TC and HC groups. Moreover, patients with cPTSD showed increased activation in the context of trauma-related words in brain regions associated with cognitive control (dlPFC, vmPFC, dACC) compared to both control groups, and a trend for increased activation in the insula compared to the HC group. Increased recruitment of regions contributing to cognitive control in patients with cPTSD, together with a lack of amygdala response may point to efforts to compensate for emotional distraction caused by the trauma-related words.

- Abstract
The purported healthy aspects of subsistence foods have led to the popularity of the Paleo diet. There has been very little focus, surprisingly, on health benefits derived from the nomadic nature of humans during the Paleolithic era. The purpose of our study was to examine total energy expenditure (TEE), total energy intake (TEI), body composition, blood lipids, and intrahepatic lipid in humans during a 12-day Alaskan backcountry expeditionary hunting (ABEH) immersion. Four healthy men (age: 42 ± 3 year, BMI: 27 ± 1 kg/m
2 ) were recruited for the study. TEE was measured using the doubly labeled water method and a food diary was utilized to assess TEI. Body composition was measured using dual energy X-ray absorptiometry (DXA); cross-sectional area of the thigh (XT) and intrahepatic lipid (IHL) were measured using molecular imaging. Blood samples were collected for the measurement of blood lipids. DXA, XT, IHL, and blood data were collected pre- and immediately post-ABEH. Results were analyzed using paired t-tests and considered significant at P < 0.05. TEE and TEI averaged 18.1 ± 1.2 and 9.1 ± 2.5 MJ/day, respectively, indicating substantial negative energy balance (-9.0 ± 1.3 MJ/day). There was a reduction in percent body fat (∆-3.3 ± 0.2%), total fat mass (∆-3.3 ± 0.4 kg), and visceral fat volume (Δ-261 ± 188 cm3 ). Lean tissue mass and XT was unchanged. There was a decrease in IHL (Δ-0.5 ± 0.1% water peak), and a trend (P = 0.055) toward reduction in LDL-cholesterol. We conclude that constancy of physical activity during negative energy balance may provide metabolic benefits above and beyond variations in diet that exist with the hunter-gatherer lifestyle., (© 2018 The Authors.
