Socioeconomic status and access to psychotherapy.

OBJECTIVE: Individuals with low socioeconomic status (SES) have significantly higher prevalence rates of mental disorders than those with higher SES, but are less likely to receive treatment. Studies from the United States show that individuals with higher SES are more likely to be offered a therapy place than those with low SES. In Germany, where the public health care system is without financial barriers, studies on access to treatment are lacking. METHOD: The present study investigated whether the SES of persons seeking psychotherapeutic help in Germany influences psychotherapists' decision to provide access to treatment. For this purpose, 504 licensed outpatient psychological psychotherapists participated in an online study, in which they read a series of case vignettes and rated how likely they would be to offer treatment in each case. SES was operationalized by occupation and language use. Additionally, we investigated whether treatment offers were affected by the disorder and the gender of the help seeker, the therapists' socioeconomic background, and other characteristics in interaction with SES. Bonferroni-corrected multifactorial repeated measures analysis of variances (ANOVAs) and mixed ANOVAs were calculated. RESULTS: Help seekers with low SES were 4.1% less likely to be offered treatment than those with moderate to high SES (F (1, 503) = 115.64; p = 0.000; η² = 0.187). The influence of SES on the probability of a therapy place offer varied significantly depending on the patient's disorder (p = 0.000): SES had a greater effect for bulimia than for depression and social anxiety disorder. Overall, the effect was small (η² = 0.026). No significant interaction between the gender of potential clients and SES was found (p = 0.062). The influence of SES on treatment accessibility varied depending on the therapeutic method for which the therapist was licensed and on the social status of the district in which the therapist's practice was located. The therapist's socioeconomic background (parental SES) did not interact with the potential client's SES. CONCLUSION: Therapist biases contributing to unequal access to treatment for individuals with low SES and other characteristics can aggravate mental health care disparities. Even though the effects we found were relatively modest, awareness of the association between SES and offers of therapy places might help practitioners to reflect on their own selection practices.

Salivary Cortisol and Alpha-Amylase in Posttraumatic Stress Disorder and Their Potential Role in the Evaluation of Cognitive Behavioral Treatment Outcomes.

Alterations in HPA-axis and autonomic nervous system activity have been associated with posttraumatic stress disorder (PTSD) development and maintenance and are potentially associated with trauma-focused cognitive behavioral therapy (TF-CBT) outcomes. We examined the role of salivary cortisol (sCort) and alpha-amylase (sAA) in PTSD and TF-CBT outcomes in German Armed Forces service members (N = 100). Participants categorized as PTSD patients (n = 39), previously deployed healthy controls (n = 33), and nondeployed healthy controls (n = 28) provided diurnal profiles of sCort and sAA; PTSD patients provided samples before, immediately after, and 3 months after an internet-based TF-CBT intervention. No group differences emerged regarding total daily sCort and sAA output or daily slopes, ps = .224-.897, fs = 0.05-0.24. Participants with PTSD demonstrated a significantly attenuated sCort awakening response compared to deployed, p = .021, d = 0.59, but not nondeployed controls, p = .918, d = 0.08. Moreover, a significantly steeper sAA awakening response emerged in PTSD patients, p = .034, d = 0.67, and deployed controls, p = .014, d = 0.80, compared to nondeployed controls. From pretreatment to posttreatment (n = 21) and posttreatment to follow-up (n = 14), stable sCort, ps = .282-.628, fs = 0.34-0.49, and sAA concentrations, ps = .068-.758, fs = 0.24-1.13 paralleled a nonsignificant treatment effect. Both PTSD and trauma exposure were associated with alterations in awakening responses, but further investigation is needed to determine whether the observed correspondence remains when PTSD symptoms significantly decline.

Demographic, sampling- and assay-related confounders of endogenous oxytocin concentrations: A systematic review and meta-analysis.

Studies on endogenous oxytocin concentrations are often criticized for the debatable comparability between specimens and the variation in reported values. We performed meta-regressions on k = 229 studies (n = 12 741 participants), testing whether specimen, extraction, sex, age, time of day, or fasting instructions influenced oxytocin measurements. Predicted oxytocin concentrations differed depending on specimen and extraction: Measurements were extremely high in unextracted blood, compared to extracted blood and other specimens. Measurements were higher in samples with more female participants and higher age. Instructions not to smoke before sampling were correlated with higher oxytocin in unextracted samples. There was no impact of instructions to refrain from eating, drinking, consume caffeine, alcohol or exercising. Oxytocin concentrations increased from morning to afternoon. Our results showed that oxytocin is differentially reflected in blood, saliva, urine and cerebrospinal fluid. Extraction impacts oxytocin measurements, particularly in blood. Considering relevant confounders might increase comparability between studies.

Evaluation of an internet-based intervention for service members of the German armed forces with deployment-related posttraumatic stress symptoms.

BACKGROUND: The present study was designed to evaluate the efficacy of a therapist-guided internet-based cognitive-behavioral therapy (iCBT) intervention for service members of the German Armed Forces with posttraumatic stress disorder (PTSD). The iCBT was adapted from Interapy, a trauma-focused evidence-based treatment based on prolonged exposure and cognitive restructuring. It lasted for 5 weeks and included 10 writing assignments (twice a week). The program included a reminder function if assignments were overdue, but no multimedia elements. Therapeutic written feedback was provided asynchronously within one working day. METHODS: Male active and former military service members were recruited from the German Armed Forces. Diagnoses were assessed with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and the Mini-International Neuropsychiatric Interview. Psychopathology was assessed at pre-treatment, post-treatment, and 3-month follow-up. Severity of PTSD was the primary outcome and anxiety was the secondary outcome. Participants were randomly allocated to a treatment group that received iCBT immediately or to a waitlist group that received iCBT after 6 weeks. Due to the overall small sample size (n = 37), the two groups were collapsed for the statistical analyses. Change during the intervention period was investigated using latent-change score models. RESULTS: Improvements in the CAPS-5 were small and not statistically significant. For anxiety, small significant improvements were observed from pre- to follow-up assessment. The dropout rate was 32.3%. CONCLUSIONS: The low treatment utilization and the high dropout rate are in line with previous findings on treatment of service members. The interpretation of the current null results for the efficacy of iCBT is limited due to the small sample size, however for military samples effect estimates were also smaller in other recent studies. Our results demonstrate the need to identify factors influencing treatment engagement and efficacy in veterans. TRIAL REGISTRATION: Australian Clinical Trials Registry ACTRN12616000956404.

Interpersonal ambivalence in obsessive-compulsive disorder.

BACKGROUND: The social attitudes and interpersonal relationships of patients with obsessive-compulsive disorder (OCD) are subject to a longstanding controversy. Whereas cognitive-behavioural researchers emphasize exaggerated pro-social attitudes in OCD like inflated responsibility and worry for other people (especially significant others), dynamic theories traditionally focus on anti-social attitudes such as latent aggression and hostility. In two recent studies, we gathered support not only for a co-existence of these seemingly opposing attitudes in OCD, but also for a functional connection: inflated responsibility in part appears to serve as a coping strategy (or "defense") against negative interpersonal feelings. AIMS: In the present study, we tested a shortened version of the Responsibility and Interpersonal Behaviours and Attitudes Questionnaire (RIBAQ-R). METHOD: The scale was administered to 34 participants with OCD and 34 healthy controls. The questionnaire concurrently measures pro-social and anti-social interpersonal attitudes across three subscales. RESULTS: In line with our prior studies, patients displayed higher scores on both exaggerated pro-social attitudes (e.g. "I suffer from a strict conscience concerning my relatives") as well as latent aggression (e.g. "Sometimes I would like to harm strangers on the street") and suspiciousness/distrust (e.g. "I cannot even trust my own family"). A total of 59% of the patients but only 12% of the healthy controls showed marked interpersonal ambivalence (defined as scores higher than one standard deviation from the mean of the nonclinical controls on both the prosocial and at least one of the two anti-social subscales). CONCLUSIONS: The study asserts high interpersonal ambivalence in OCD. Further research is required to pinpoint both the dynamic and causal links between opposing interpersonal styles. Normalization and social competence training may prove beneficial to resolve the apparent problems of patients with OCD regarding anger expression and social conflict management.

Who benefits from guided internet-based interventions? A systematic review of predictors and moderators of treatment outcome.

To our knowledge, no systematic review has been conducted on predictors or moderators of treatment outcome across diagnoses in guided internet-based interventions (IBIs) for adults. To identify who benefits from this specific format and therein inform future research on improving patient-treatment fit, we aimed to aggregate results of relevant studies. 2100 articles, identified by searching the databases PsycInfo, Ovid Medline, and Pubmed and through snowballing, were screened in April/May 2021 and October 2022. Risk of bias and intra- and interrater reliability were assessed. Variables were grouped by predictor category, then synthesized using vote counting based on direction of effect. N = 60 articles were included in the review. Grouping resulted in 88 predictors/moderators, of which adherence, baseline symptoms, education, age, and gender were most frequently assessed. Better adherence, treatment credibility, and working alliance emerged as conclusive predictors/moderators for better outcome, whereas higher baseline scores predicted more reliable change but higher post-treatment symptoms. Results of all other predictors/moderators were inconclusive or lacked data. Our review highlights that it is currently difficult to predict, across diagnoses, who will benefit from guided IBIs. Further rigorous research is needed to identify predictors and moderators based on a sufficient number of studies. PROSPERO registration: CRD42021242305.

Research Into Evidence-Based Psychological Interventions Needs a Stronger Focus on Replicability.

Background: It is a precondition for evidence-based practice that research is replicable in a wide variety of clinical settings. Current standards for identifying evidence-based psychological interventions and making recommendations for clinical practice in clinical guidelines include criteria that are relevant for replicability, but a better understanding as well refined definitions of replicability are needed enabling empirical research on this topic. Recent advances on this issue were made in the wider field of psychology and in other disciplines, which offers the opportunity to define and potentially increase replicability also in research on psychological interventions. Method: This article proposes a research strategy for assessing, understanding, and improving replicability in research on psychological interventions. Results/Conclusion: First, we establish a replication taxonomy ranging from direct to conceptual replication adapted to the field of research on clinical interventions, propose study characteristics that increase the trustworthiness of results, and define statistical criteria for successful replication with respect to the quantitative outcomes of the original and replication studies. Second, we propose how to establish such standards for future research, i.e., in order to design future replication studies for psychological interventions as well as to apply them when investigating which factors are causing the (non-)replicability of findings in the current literature.

[Differential Effects of an Internet-Based Cognitive-Behavioral Writing Therapy for Reducing PTSD Symptoms after Intensive Care: Results of a Per-Protocol Analysis]. / Differentielle Wirksamkeit einer internetbasierten kognitiv-behavioralen Schreibtherapie zur Reduktion von PTBS-Symptomen nach intensivmedizinischer Behandlung: Ergebnisse einer Per-Protokoll-Analyse.

OBJECTIVE: To investigate the differential effects of an internet-based cognitive-behavioral writing therapy (iCBT) on post-traumatic stress disorder (PTSD) symptoms after intensive care in patients and their spouses. METHODS: This reanalysis of a randomized controlled trial compared PTSD symptom severity (measured by PCL-5) before and after therapy considering potential influencing factors in the per-protocol population. RESULTS: A significant reduction in post-traumatic symptom severity after iCBT was found. Eleven of the 25 treated participants showed a clinically significant change (PCL-5 difference≥10 points). The number of words written by the participants in the therapy modules had a significant impact on iCBT efficacy. CONCLUSION: iCBT appears to be a promising option to augment therapy for PTSD, particularly for physically impaired patients following critical illness.

Eleven strategies for making reproducible research and open science training the norm at research institutions.

Reproducible research and open science practices have the potential to accelerate scientific progress by allowing others to reuse research outputs, and by promoting rigorous research that is more likely to yield trustworthy results. However, these practices are uncommon in many fields, so there is a clear need for training that helps and encourages researchers to integrate reproducible research and open science practices into their daily work. Here, we outline eleven strategies for making training in these practices the norm at research institutions. The strategies, which emerged from a virtual brainstorming event organized in collaboration with the German Reproducibility Network, are concentrated in three areas: (i) adapting research assessment criteria and program requirements; (ii) training; (iii) building communities. We provide a brief overview of each strategy, offer tips for implementation, and provide links to resources. We also highlight the importance of allocating resources and monitoring impact. Our goal is to encourage researchers - in their roles as scientists, supervisors, mentors, instructors, and members of curriculum, hiring or evaluation committees - to think creatively about the many ways they can promote reproducible research and open science practices in their institutions.

Mental Health and Loneliness in University Students During the COVID-19 Pandemic in Germany: A Longitudinal Study.

The COVID-19 pandemic and its preventive measures had adverse consequences for mental health. However, knowledge of mental health trajectories across the pandemic is limited. This study investigated the mental health levels and changes among university students during the pandemic and lockdown in Germany, as well as their associated factors. We surveyed students' mental health (N = 363, 68% female) with the patient health questionnaire (PHQ-8) and the generalized anxiety disorder scale (GAD-7) during the first easing phase (July 2020; time 1) and the second lockdown (November 2020; time 2). Cut-off scores from the GAD-7 and PHQ-8 were used to determine clinically relevant symptoms and to define trajectory groups. Sociodemographic and pandemic-related data were assessed (e.g., coping with academic life, social contacts) as well as loneliness, stress, repetitive negative thinking, quality of life, and perceived social support. Paired t-test, multiple regression, and repeated-measures ANOVA were applied. Means and prevalence rates for symptoms of depression (38.8%) and anxiety (25.6%) did not differ between time 1 and time 2, and most students were asymptomatic on the PHQ-8 (44.4%) and the GAD-7 (56.3%) across the pandemic. Feelings of loneliness significantly increased from time 1 to time 2, d = -0.30, [-0.47, -0.13], with higher symptom levels in symptomatic groups at time 2 and greater increases in the asymptomatic groups. Levels of stress, repetitive negative thinking, quality of life, and social support did not differ during the pandemic. At time 1, loneliness and repetitive negative thinking were associated with anxiety and depressive symptoms. Anxiety and depressive symptoms were prevalent among students, and increased levels of loneliness during the pandemic were associated with elevated symptoms and differing trajectories. Further research using representative and larger samples should determine the long-term impact of the pandemic on mental health and loneliness to identify vulnerable students and offer adequate support.

Evidence-based individual psychotherapy for complex posttraumatic stress disorder and at-risk groups for complex traumatization: A meta-review.

BACKGROUND: The current meta-review of meta-analyses on psychotherapy research for complex post-traumatic stress disorder (CPTSD) and samples at risk of complex traumatization has three aims: first, to provide an overview of efficacy of individual psychotherapies; second, to compare the quality of the meta-analyses; and third, to assess statistical power. METHODS: The literature search was conducted until August 2020. Meta-analyses providing individual treatment effect estimates focusing on CPTSD or samples at risk of complex traumatization (i.e., victims of childhood sexual abuse (CSA), war or torture, refugees, and veterans with PTSD) were eligible for inclusion. The effect sizes were classified according to Cohen as small, medium, or large. The "A MeaSurement Tool to Assess systematic Reviews" (AMSTAR) was applied to assess the quality of the meta-analyses, and power was assessed post-hoc. RESULTS: Twenty-four meta-analyses were suitable for inclusion. The efficacy of the interventions varied (g = -0.04 (CI -0.39; 0.48), controlled, to d = 2.73 (1.69; 3.76), uncontrolled). Overall, 16 effect estimates were large. On average, the quality of the meta-analyses was good (average AMSTAR total score 7.71 points (range 3-11). Considering quality assessments and power together, nine meta-analyses were evaluated as high quality. LIMITATIONS: No meta-analysis for CPTSD was eligible and the number of individuals with complex traumatization was not directly assessed in the at-risk groups. CONCLUSIONS: For at-risk groups for complex traumatization, on average, good-quality empirical evidence exists. Given the limited research on CPTSD, future studies are needed to further investigate the efficacy of interventions.

Internet-based cognitive-behavioural writing therapy for reducing post-traumatic stress after severe sepsis in patients and their spouses (REPAIR): results of a randomised-controlled trial.

OBJECTIVES: To investigate the efficacy, safety and applicability of internet-based, therapist-led partner-assisted cognitive-behavioural writing therapy (iCBT) for post-traumatic stress disorder (PTSD) symptoms after intensive care for sepsis in patients and their spouses compared with a waitlist (WL) control group. DESIGN: Randomised-controlled, parallel group, open-label, superiority trial with concealed allocation. SETTING: Internet-based intervention in Germany; location-independent via web-portal. PARTICIPANTS: Patients after intensive care for sepsis and their spouses of whom at least one had a presumptive PTSD diagnosis (PTSD-Checklist (PCL-5)≥33). Initially planned sample size: 98 dyads. INTERVENTIONS: ICBT group: 10 writing assignments over a 5-week period; WL control group: 5-week waiting period. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome: pre-post change in PTSD symptom severity (PCL-5). SECONDARY OUTCOMES: remission of PTSD, depression, anxiety and somatisation, relationship satisfaction, health-related quality of life, premature termination of treatment. Outcomes measures were applied pre and post treatment and at 3, 6 and 12 months follow-up. RESULTS: Twenty-five dyads representing 34 participants with a presumptive PTSD diagnosis were randomised and analysed (ITT principle). There was no evidence for a difference in PCL-5 pre-post change for iCBT compared with WL (mean difference -0.96, 95% CI (-5.88 to 3.97), p=0.703). No adverse events were reported. Participants confirmed the applicability of iCBT. CONCLUSIONS: ICBT was applied to reduce PTSD symptoms after intensive care for sepsis, for the first time addressing both patients and their spouses. It was applicable and safe in the given population. There was no evidence for the efficacy of iCBT on PTSD symptom severity. Due to the small sample size our findings remain preliminary but can guide further research, which is needed to determine if modified approaches to post-intensive care PTSD may be more effective.

Trauma-related but not PTSD-related increases in hair cortisol concentrations in military personnel.

Dysregulated hypothalamic-pituitary-adrenal (HPA) axis functioning has been associated with posttraumatic stress disorder (PTSD). The current literature is inconsistent regarding this association, possibly due to confounding influences. Hair cortisol concentrations (HCC) allow for retrospective assessment of cumulative HPA axis secretion over several weeks and are considered a trait-like marker of HPA axis activity. Three groups of active and former German Armed Forces service members, comprising PTSD patients (n = 19), healthy controls with deployment-related trauma exposure (n = 10), and non-deployed healthy controls (n = 10) provided samples for HCC analysis. We observed significantly higher HCC in the PTSD and the deployed compared to the non-deployed group. HCC was neither significantly correlated with perceived chronic stress, nor with PTSD severity within patients. The results suggest a differential impact of trauma exposure on HPA axis activity and highlight the notion of cumulative, retrospective cortisol secretion as a psychobiological indicator of trauma exposure.

Attentional bias in German Armed Forces veterans with and without posttraumatic stress symptoms - An eye-tracking investigation and group comparison.

BACKGROUND AND OBJECTIVES: Most eye tracking based paradigms evidence patterns of sustained attention on threat coupled with low evidence for vigilance to or avoidance of threat in posttraumatic stress symptoms (PTSS). Still, eye tracking data on attention bias is particularly limited for military population. This eye tracking study investigated attentional bias in PTSS in a sample of German Armed Forces veterans. METHODS: Veterans with deployment-related PTSS (N = 24), veterans with deployment-related traumatization without PTSS (N = 28), and never-deployed healthy veterans (N = 18) were presented with pairs of combat and neutral pictures, pairs of general threat and neutral pictures, and pairs of emotional and neutral faces. Their eye gazes were tracked during a free viewing task. 3 x 3 x 2 mixed general linear model analyses were conducted. Internal consistency of attention bias indicators was calculated for the entire sample and within groups. RESULTS: Veterans with PTSS dwelled longer on general threat AOIs in contrast to non-exposed controls and shorter on general threat and combat associated neutral AOIs in contrast to both control groups. Veterans with PTSS entered faster to general threat AOIs than non-exposed controls. Veterans with PTSS showed circumscribed higher attention fluctuation in contrast to controls. Internal consistency varied across attention bias indicators. LIMITATIONS: Statistical power was reduced due to recruitment difficulties. CONCLUSIONS: Evidence is provided for the maintenance hypothesis in PTSS. No robust evidence is provided for hypervigilant behavior in PTSS. Findings on attention bias variability remain unclear, calling for more investigations in this field.

Posttraumatic stress in adult civilians exposed to violent conflict, war and associated human rights abuses in the Eastern Mediterranean Region: A systematic review and meta-analysis.

BACKGROUND: The Eastern Mediterranean Region (EMR) is the stage of the world's most violent conflicts and the origin of the largest refugee population worldwide. These conflicts can result in symptoms of posttraumatic stress (PTS). To date, no comprehensive meta-analysis on proportions of PTS in civilians from the EMR has been conducted. Sample characteristics, methodological, conflict-related and displacement-related factors might affect rates of PTS. METHODS: A systematic literature search for studies investigating PTS in adult civilians from the EMR was conducted until March 2020 and resulted in 118 individual study samples that were suitable for inclusion. A quality assessment was conducted. A random effects meta-analysis on proportions and sensitivity analyses were performed, and a 95% prediction interval was calculated. Subgroup analyses to identify moderators (e.g. diagnostic instruments, displacement) were conducted. RESULTS: The quality of the included study samples varied. The pooled estimate of proportions from all 118 study samples was 0.31 (95% CI: 0.27 - 0.35). Heterogeneity was considerable (Q = 10151.58, p < .0001; I2 = 98.64%). The prediction interval was 0.01 to 0.76. The results remained unchanged after excluding nine outlier study samples. Heterogeneity remained high in all subgroups (range of I2: 87.91 to 99.62). LIMITATIONS: Due to heterogeneity the pooled estimate cannot be interpreted. Moderators contributing to heterogeneity could not be detected. CONCLUSIONS: The proportion of symptoms of PTS in civilians from the EMR varies considerably. The prediction interval indicates that the true rate falls between 1% and 76%. Future studies need to identify variables that affect heterogeneity.

Associations between oxytocin and vasopressin concentrations, traumatic event exposure and posttraumatic stress disorder symptoms: group comparisons, correlations, and courses during an internet-based cognitive-behavioural treatment.

Background: Posttraumatic stress disorder (PTSD) is characterized by impairments in extinction learning and social behaviour, which are targeted by trauma-focused cognitive behavioural treatment (TF-CBT). The biological underpinnings of TF-CBT can be better understood by adding biomarkers to the clinical evaluation of interventions. Due to their involvement in social functioning and fear processing, oxytocin and arginine vasopressin might be informative biomarkers for TF-CBT, but to date, this has never been tested. Objective: To differentiate the impact of traumatic event exposure and PTSD symptoms on blood oxytocin and vasopressin concentrations. Further, to describe courses of PTSD symptoms, oxytocin and vasopressin during an internet-based TF-CBT and explore interactions between these parameters. Method: We compared oxytocin and vasopressin between three groups of active and former male service members of the German Armed Forces (n = 100): PTSD patients (n = 39), deployed healthy controls who experienced a deployment-related traumatic event (n = 33) and non-deployed healthy controls who never experienced a traumatic event (n = 28). PTSD patients underwent a 5-week internet-based TF-CBT. We correlated PTSD symptoms with oxytocin and vasopressin before treatment onset. Further, we analysed courses of PTSD symptoms, oxytocin and vasopressin from pre- to post-treatment and 3 months follow-up, as well as interactions between the three parameters. Results: Oxytocin and vasopressin did not differ between the groups and were unrelated to PTSD symptoms. PTSD symptoms were highly stable over time, whereas the endocrine parameters were not, and they also did not change in mean. Oxytocin and vasopressin were not associated with PTSD symptoms longitudinally. Conclusions: Mainly due to their insufficient intraindividual stability, single measurements of endogenous oxytocin and vasopressin concentrations are not informative biomarkers for TF-CBT. We discuss how the stability of these biomarkers might be increased and how they could be better related to the specific impairments targeted by TF-CBT.

Antecedentes: El trastorno de estrés postraumático (TEPT) se caracteriza por deficiencias en el aprendizaje de extinción y el comportamiento social, que son el objetivo del tratamiento cognitivo conductual centrado en el trauma (TF-CBT). Los fundamentos biológicos de TF-CBT se pueden entender mejor agregando biomarcadores a la evaluación clínica de las intervenciones. Debido a su participación en el funcionamiento social y el procesamiento del miedo, la oxitocina y la arginina vasopresina podrían ser biomarcadores informativos para la TF-CBT, pero hasta la fecha, esto nunca se ha probado.Objetivo: Diferenciar el impacto de la exposición a un evento traumático y los síntomas del TEPT en las concentraciones de oxitocina y vasopresina en la sangre. Además, para describir la evolución de los síntomas del TEPT, la oxitocina y la vasopresina durante una TF-CBT basada en Internet y explorar las interacciones entre estos parámetros.Método: Comparamos la oxitocina y la vasopresina entre tres grupos de militares activos y ex militares de las Fuerzas Armadas Alemanas (n = 100): pacientes con TEPT (n = 39), controles sanos desplegados que experimentaron un evento traumático relacionado con el despliegue (n = 33) y controles sanos no desplegados que nunca experimentaron un evento traumático (n = 28). Los pacientes con TEPT se sometieron a una TF-CBT basada en Internet durante 5 semanas. Correlacionamos los síntomas del TEPT con la oxitocina y la vasopresina antes del inicio del tratamiento. Además, analizamos la evolución de los síntomas del TEPT, la oxitocina y la vasopresina antes y después del tratamiento y el seguimiento de 3 meses, así como las interacciones entre los tres parámetros.Resultados: La oxitocina y la vasopresina no difirieron entre los grupos y no se relacionaron con los síntomas del TEPT. Los síntomas del TEPT fueron muy estables en el tiempo, mientras que los parámetros endocrinos no lo fueron, y tampoco cambiaron en la media. La oxitocina y la vasopresina no se asociaron con los síntomas del TEPT de forma longitudinal.Conclusiones: Principalmente debido a su estabilidad intraindividual insuficiente, las mediciones únicas de las concentraciones de oxitocina y vasopresina endógenas no son biomarcadores informativos para TF-CBT. Discutimos cómo podría aumentarse la estabilidad de estos biomarcadores y cómo podrían relacionarse mejor con las deficiencias específicas a las que se dirige TF-CBT.

Dyadic post-traumatic stress after intensive care: Case report of a sepsis patient and his wife.

INTRODUCTION: Following intensive care treatment, patients and thier spouse often report traumatic memories that are frequently associated with post-traumatic stress symptoms. In this case report, we describe the case of a sepsis survivor and his wife who both suffered concurrently from intensive care associated post-traumatic stress symptoms as long-term sequelae. Both were treated with internet-based cognitive-behaviuoral writing therapy (iCBT) for post-traumatic stress disorder (PTSD) after intensive care. METHODS: Traumatic memories recalled during exposure in sensu as part of iCBT are described. Outcome data measured before, during and after psychotherapeutic treatment were analyzed. FINDINGS: Both, the patient and his wife showed characteristic symptoms of PTSD three years after discharge from the intensive care unit (ICU) comprising of intrusions, negative emotions, and hyperarousal. They reported unpleasant ICU memories from a patient's and relative's perspective, respectively. In both, the patient and his wife, a decline of symptoms with respect to all outcome measures during the course of iCBT from pre-treatment to three-month follow-up was observed. CONCLUSION: Experiences of critical illness and intensive care can lead to post-traumatic stress in patients and their partners. Hence, it may be useful to offer mental health screening and psychotherapeutic treatment options to both ICU patients and their partners.

The Relation Between Attachment and Depression in Children and Adolescents: A Multilevel Meta-Analysis.

Insecure attachment to primary caregivers is associated with the development of depression symptoms in children and youth. This association has been shown by individual studies testing the relation between attachment and depression and by meta-analyses focusing on broad internalizing problems instead of depression or adult samples only. We therefore meta-analytically examined the associations between attachment security and depression in children and adolescents, using a multilevel approach. In total, 643 effect sizes were extracted from 123 independent samples. A significant moderate overall effect size was found (r = .31), indicating that insecure attachment to primary caregivers is associated with depression. Multivariate analysis of the significant moderators that impacted on the strength of the association between attachment security and depression showed that country of the study, study design, gender, the type of attachment, and the type of instrument to assess attachment uniquely contributed to the explanation of variance. This study suggests that insecure attachment may be a predictor of the development of depression in children and adolescents. When treating depression in children, attachment should therefore be addressed.

Associations Between Difficulties in Emotion Regulation and Post-Traumatic Stress Disorder in Deployed Service Members of the German Armed Forces.

BACKGROUND: Experiencing a traumatic event can lead to post-traumatic stress disorder (PTSD), but not every traumatized person develops PTSD. Several protective and risk factors have been identified in civilians and veterans to explain why some individuals develop PTSD and others do not. However, no research has confirmed the relationship between emotion regulation and PTSD in deployed German Armed Forces service members after a foreign assignment. Previous studies have identified some protective factors, such as social support, social acknowledgment, specific personal values, and posttraumatic growth, as well as risk factors, like moral injury and emotion regulation. Thus, the aim of the present study is to confirm the relationship between emotion regulation and PTSD and to test for factors that are associated with higher severity of PTSD symptoms in such a sample. METHODS: A post-hoc secondary analysis was conducted on data collected in a randomized controlled trial. Participants (N = 72) were male active and former military service members that have returned from deployment and were recruited from the German Armed Forces. These participants were separated into two groups according to PTSD diagnosis based on the results of a structured diagnostic interview. Data from evaluation questionnaires administered upon entry into the study were subjected to a cross-sectional analysis. The measures included the severity of PTSD symptoms, clusters of PTSD symptoms, clinical measures, and several measures assessing PTSD-related constructs. Analyses included the Spearman rank correlation coefficient, X2 tests for nominal data, Mann-Whitney U-tests for non-parametric data, and a mediation analysis. RESULTS: The results of the mediation analysis revealed that difficulties in emotion regulation were significantly associated with the severity of PTSD symptoms, which was mediated by social acknowledgment and experimental avoidance but not by moral injury. The analyses showed that the severity of PTSD symptoms and all clusters of PTSD symptoms were significantly associated with most of the measured constructs in expectable directions. Participants in the PTSD group showed significantly higher mean scores on questionnaires measuring constructs that have been associated with PTSD, like emotion regulation and moral injury. They also showed lower mean scores in questionnaires for social support and social acknowledgment as a victim or survivor than participants in the non-PTSD group. CONCLUSION: The present results show that difficulties in emotion regulation are directly associated with the severity of PTSD symptoms in service members of the German Armed Forces. This association is mediated by social acknowledgment and experimental avoidance, but not by moral injury. Thus, future studies should investigate these potentially crucial factors for better understanding of the development and maintenance of PTSD in service members of the German Armed Forces after deployment to create possible treatment adaptions.

Trauma-focused psychodynamic therapy and STAIR Narrative Therapy of post-traumatic stress disorder related to childhood maltreatment: trial protocol of a multicentre randomised controlled trial assessing psychological, neurobiological and health economic outcomes (ENHANCE).

INTRODUCTION: Success rates of psychotherapy in post-traumatic stress disorder related to childhood maltreatment (PTSD-CM) are limited. METHODS AND ANALYSIS: Observer-blind multicentre randomised clinical trial (A-1) of 4-year duration comparing enhanced methods of STAIR Narrative Therapy (SNT) and of trauma-focused psychodynamic therapy (TF-PDT) each of up to 24 sessions with each other and a minimal attention waiting list in PTSD-CM. Primary outcome is severity of PTSD (Clinician-Administered PTSD Scale for DSM-5 total) assessed by masked raters. For SNT and TF-PDT, both superiority and non-inferiority will be tested. Intention-to-treat analysis (primary) and per-protocol analysis (secondary). Assessments at baseline, after 10 sessions, post-therapy/waiting period and at 6 and 12 months of follow-up.

Data management, randomisation and monitoring will be performed by an independent European Clinical Research Infrastructure Network (ECRIN)-certified data coordinating centre for clinical trials (KKS Marburg). Report of AEs to a data monitoring and safety board. Complementing study A-1, four inter-related add-on projects, including subsamples of the treatment study A-1, will examine (1) treatment integrity (adherence and competence) and moderators and mediators of outcome (B-1); (2) biological parameters (B-2, eg, DNA damage, reactive oxygen species and telomere shortening); (3) structural and functional neural changes by neuroimaging (B-3) and (4) cost-effectiveness of the treatments (B-4, costs and utilities). ETHICS AND DISSEMINATION: Approval by the institutional review board of the University of Giessen (AZ 168/19).
