Effect of acute and long-term exercise on leptin levels in depressed outpatients.

BACKGROUND: Depression is a leading cause of disability worldwide and a significant contributor to the global burden of disease. Altered leptin levels are known to be associated with depressive symptoms, however discrepancies in the results of increased or decreased levels exist. Due to various limitations associated with commonly used antidepressant drugs, alternatives such as exercise therapy are gaining more importance. Therefore, the current study investigates whether depressed patients have higher leptin levels compared to healthy controls and if exercise is efficient to reduce these levels. METHODS: Leptin levels of 105 participants with major depressive disorder (MDD; 45.7% female, age mean ± SEM: 39.1 ± 1.0) and 34 healthy controls (HC; 61.8% female, age mean ± SEM: 36.0 ± 2.0) were measured before and after a bicycle ergometer test. Additionally, the MDD group was separated into three groups: two endurance exercise intervention groups (EX) differing in their intensities, and a waiting list control group (WL). Leptin levels were measured pre and post a 12-week exercise intervention or the waiting period. RESULTS: Baseline data showed no significant differences in leptin levels between the MDD and HC groups. As expected, correlation analyses displayed significant relations between leptin levels and body weight (HC: r = 0.474, p = 0.005; MDD: r = 0.198, p = 0.043) and even more with body fat content (HC: r = 0.755, p < 0.001; MDD: r = 0.675, p < 0.001). The acute effect of the bicycle ergometer test and the 12-week training intervention showed no significant changes in circulating leptin levels. CONCLUSION: Leptin levels were not altered in patients with major depression compared to healthy controls and exercise, both the acute response and after 12 weeks of endurance training, had no effect on the change in leptin levels. TRIAL REGISTRATION: The study was registered at the German register for clinical studies (DRKS) and the International Clinical Trials Registry Platform of the World Health Organization https://trialsearch.who.int/Trial2.aspx?TrialID=DRKS00008869 on 28/07/2015.

Is adherence to dialectic behaviour therapy for post-traumatic stress disorder (PTSD) and cognitive processing therapy related to treatment outcome in PTSD after childhood abuse?

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.

Higher therapist adherence to cognitive processing therapy was associated with higher treatment gains in women with post-traumatic stress disorder (PTSD) after childhood abuse.Adherence was related to higher reductions in symptom severity of PTSD, borderline symptoms, and dissociation intensity.Adherence to dialectical behaviour therapy for PTSD did not show a strong association with treatment outcome.

Does treatment specific-, disorder specific- or general therapeutic competence predict symptom reduction in posttraumatic stress disorder?

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.

Three different types of therapeutic competence and their association to treatment gains in women with posttraumatic stress disorder after child abuse were assessed.Therapist competence was high in all three domains of competence.No association was found between any of the competence types and reduction in posttraumatic stress disorder symptoms.

Sexual Dysfunctions in Women with Posttraumatic Stress Disorder Following Childhood Sexual Abuse: Prevalence Rates According to DSM-5 and Clinical Correlates.

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.

Impact of new country, discrimination, and acculturation-related factors on depression and anxiety among ex-Soviet Jewish migrants: data from a population-based cross-national comparison study.

Migration, displacement, and flight are major worldwide phenomena and typically pose challenges to mental health. Therefore, migrants' mental health, and the factors which may predict it, have become an important research subject. The present population-based cross-national comparison study explores symptoms of depression, anxiety, and somatization, as well as quality-of-life in samples of ex-Soviet Jewish migrants settling in three new countries: Germany, Austria and Israel, as well as in a sample of non-migrant ex-Soviet Jews in their country of origin, Russia. In the current study, we investigate the relationship of perceived xenophobiа and antisemitism, acculturation attitudes, ethnic and national identity, as well as affiliation with Jewish religion and culture to the psychological well-being of these migrants. Furthermore, we consider xenophobic and antisemitic attitudes as well as the acculturation orientation of the new countries' societies, assessed in the native control samples. Our data suggest that attitudes of the new country's society matter for the mental health of this migrant group. We conclude that the level of distress among ex-Soviet Jewish migrants seems to depend, among other factors, on the characteristics of the new country and/or specific interactions of the migrant population with the society they are settling in.

Religiosity, perceived anti-Semitism, xenophobia and mental health: Experiences of Jewish immigrants from the former Soviet Union in Austria and Germany.

Research about the relation between migration and mental health as well as factors influencing the mental health of migrants has been growing because challenges of migration can constitute a significant mental health burden. However, its divergent findings seem to reflect group-specific differences, e.g., regarding country of origin and receiving country. Almost no empirical studies about individual migrant groups in different receiving countries have been undertaken so far. The present population-based study explores symptoms of depression, anxiety, and somatization as well as quality of life in an Austrian and a German sample of ex-Soviet Jewish migrants. We mainly investigate the relationship of religiosity and perceived xenophobic and anti-Semitic discrimination to the psychological condition of the migrants. Standardized self-report scales, specifically the Beck-Depression-Inventory-II (BDI), State-Trait-Anxiety-Inventory (STAI), Brief Symptom Inventory (BSI), and WHO Quality of Life Questionnaire (WHOQOL-BREF), were used to measure mental health. Ex-Soviet Jewish migrants in Austria showed significantly more symptoms of depression than those in Germany. Regression analyses support a protective effect of religiosity on mental health in the sample in Germany and an adverse effect of perceived discrimination in the sample in Austria. The present study reveals a less favorable situation for ex-Soviet Jewish migrants in Austria, in terms of income, residence status, and xenophobic attitudes in the local population, compared to the group in Germany. Furthermore, our data suggest that the receiving country matters for the mental health of this migrant group. However, further research is needed to support these conclusions.

Physical exercise training as preceding treatment to cognitive behavioral therapy in mild to moderate major depressive disorder: A randomized controlled trial.

BACKGROUND: Many patients with major depressive disorder (MDD) remain untreated or do not respond to cognitive behavioral therapy (CBT). Physical exercise shows antidepressive effects and may serve as an effective augmentation treatment. However, research on combining exercise with CBT is sparse in MDD and underlying mechanisms of exercise are not well understood to date. METHODS: 120 outpatients with MDD were randomized to either a high intensity exercise group (HEX), a low intensity exercise group (LEX), or a waiting list control group (WL). After 12 weeks of exercise training or waiting period, all patients received a manualized CBT. RESULTS: Seventy-five patients with MDD completed both the exercise program/ waiting period and the CBT. While physical fitness improved in HEX after the exercise program, it did not change in LEX and WL. Depressive symptoms improved in all three groups from baseline to post-CBT and the group by time interaction was not significant. Regression analyses revealed that the amount of fitness improvement during exercise predicted the subsequent CBT response. LIMITATIONS: The dropout rate was relatively high, preparatory CBT sessions during exercise / waiting period may have influenced depressive symptoms, and no patients with severe MDD were included. CONCLUSIONS: High intense physical exercise did not lead to a general enhancement of CBT outcome, but higher increases in physical fitness seem to improve symptom change during CBT. Our results suggest that the implementation of more individually tailored exercise programs could be a promising approach for future research and clinical practice.

Behavioural and functional evidence revealing the role of RBFOX1 variation in multiple psychiatric disorders and traits.

Common variation in the gene encoding the neuron-specific RNA splicing factor RNA Binding Fox-1 Homolog 1 (RBFOX1) has been identified as a risk factor for several psychiatric conditions, and rare genetic variants have been found causal for autism spectrum disorder (ASD). Here, we explored the genetic landscape of RBFOX1 more deeply, integrating evidence from existing and new human studies as well as studies in Rbfox1 knockout mice. Mining existing data from large-scale studies of human common genetic variants, we confirmed gene-based and genome-wide association of RBFOX1 with risk tolerance, major depressive disorder and schizophrenia. Data on six mental disorders revealed copy number losses and gains to be more frequent in ASD cases than in controls. Consistently, RBFOX1 expression appeared decreased in post-mortem frontal and temporal cortices of individuals with ASD and prefrontal cortex of individuals with schizophrenia. Brain-functional MRI studies demonstrated that carriers of a common RBFOX1 variant, rs6500744, displayed increased neural reactivity to emotional stimuli, reduced prefrontal processing during cognitive control, and enhanced fear expression after fear conditioning, going along with increased avoidance behaviour. Investigating Rbfox1 neuron-specific knockout mice allowed us to further specify the role of this gene in behaviour. The model was characterised by pronounced hyperactivity, stereotyped behaviour, impairments in fear acquisition and extinction, reduced social interest, and lack of aggression; it provides excellent construct and face validity as an animal model of ASD. In conclusion, convergent translational evidence shows that common variants in RBFOX1 are associated with a broad spectrum of psychiatric traits and disorders, while rare genetic variation seems to expose to early-onset neurodevelopmental psychiatric disorders with and without developmental delay like ASD, in particular. Studying the pleiotropic nature of RBFOX1 can profoundly enhance our understanding of mental disorder vulnerability.

Scales for assessing therapeutic adherence and competence in dialectical behaviour therapy for PTSD: development and analysis of psychometric properties.

Background: The assessment of therapeutic adherence and competence is essential to understand mechanisms that contribute to treatment outcome. Nevertheless, their assessment is often neglected in psychotherapy research. Aims/Objective: To develop an adherence and a treatment-specific competence rating scale for Dialectical Behaviour Therapy for Posttraumatic Stress Disorder (DBT-PTSD), and to examine their psychometric properties. Global cognitive behavioural therapeutic competence and disorder-specific therapeutic competence were assessed using already existing scales to confirm their psychometric properties in our sample of patients with PTSD and emotion regulation difficulties. Method: Two rating scales were developed using an inductive procedure. 155 videotaped therapy sessions from a multicenter randomised controlled trial were rated by trained raters using these scales, 40 randomly chosen videotapes involving eleven therapists and fourteen patients were doubly rated by two raters. Results: Both the adherence scale (Patient-level ICC = .98; αs = .65; α p = .75) and the treatment-specific competence scale (Patient-level ICC = .98; αs = .78; α p = .82) for DBT-PTSD showed excellent interrater - and good reliability on the patient level. Content validity, including relevance and appropriateness of all items, was confirmed by experts in DBT-PTSD for the new treatment-specific competence scale. Conclusion: Our results indicate that both scales are reliable instruments. They will be useful to examine possible effects of adherence and treatment-specific competence on DBT-PTSD treatment outcome.

Antecedentes: La evaluación de la adherencia y la competencia terapéuticas es esencial para comprender las posibles intervenciones y los mecanismos que contribuyen al resultado del tratamiento. Sin embargo, su evaluación es a menudo descuidada en la investigación en psicoterapia. Objetivos: El objetivo del presente estudio fue desarrollar una escala de valoración de la adherencia y de la competencia específica del tratamiento para la Terapia Dialéctica Conductual para el Trastorno de Estrés Postraumático (DBT-PTSD, en sus siglas en inglés), y examinar sus propiedades psicométricas. Además, se evaluó la competencia terapéutica cognitivo-conductual global y la competencia terapéutica específica del trastorno utilizando escalas ya existentes para confirmar sus propiedades psicométricas en nuestra muestra de pacientes con TEPT y dificultades de regulación de las emociones. Método: Se desarrollaron dos escalas de calificación utilizando un procedimiento inductivo. 155 sesiones de terapia grabadas en video de un ensayo controlado aleatorizado multicéntrico fueron calificadas por evaluadores entrenados utilizando estas escalas, 40 videos elegidos al azar que involucraron a once terapeutas y catorce pacientes fueron doblemente evaluados por dos evaluadores. Resultados: Tanto la escala de adherencia (CCI a nivel de paciente = 0,98; αs = 0,65; α p = 0,75) como la escala de competencia específica para el tratamiento (CCI a nivel de paciente = 0,98; αs = 0,78; α p = 0,82) para la DBT-PTSD mostraron una excelente fiabilidad entre evaluadores y buena a nivel de paciente. La validez del contenido, incluyendo la relevancia y adecuación de todos los ítems, fue confirmada por expertos en DBT-PTSD para la nueva escala de competencia específica para el tratamiento. Conclusión: Nuestros resultados indican que ambas escalas son instrumentos fiables. Serán útiles para examinar los posibles efectos de la adherencia y de la competencia específica para el tratamiento en el resultado del tratamiento DBT-PTSD.

Women with abuse-related posttraumatic stress disorder sleep more fitfully but just as long as healthy controls: an actigraphic study.

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.

Treating adults with a dual diagnosis of borderline personality disorder and posttraumatic stress disorder related to childhood abuse: Results from a randomized clinical trial.

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.

Efficacy of temporally intensified exposure for anxiety disorders: A multicenter randomized clinical trial.

BACKGROUND: The need to optimize exposure treatments for anxiety disorders may be addressed by temporally intensified exposure sessions. Effects on symptom reduction and public health benefits should be examined across different anxiety disorders with comorbid conditions. METHODS: This multicenter randomized controlled trial compared two variants of prediction error-based exposure therapy (PeEx) in various anxiety disorders (both 12 sessions + 2 booster sessions, 100 min/session): temporally intensified exposure (PeEx-I) with exposure sessions condensed to 2 weeks (n = 358) and standard nonintensified exposure (PeEx-S) with weekly exposure sessions (n = 368). Primary outcomes were anxiety symptoms (pre, post, and 6-months follow-up). Secondary outcomes were global severity (across sessions), quality of life, disability days, and comorbid depression. RESULTS: Both treatments resulted in substantial improvements at post (PeEx-I: dwithin = 1.50, PeEx-S: dwithin = 1.78) and follow-up (PeEx-I: dwithin = 2.34; PeEx-S: dwithin = 2.03). Both groups showed formally equivalent symptom reduction at post and follow-up. However, time until response during treatment was 32% shorter in PeEx-I (median = 68 days) than PeEx-S (108 days; TRPeEx-I = 0.68). Interestingly, drop-out rates were lower during intensified exposure. PeEx-I was also superior in reducing disability days and improving quality of life at follow-up without increasing relapse. CONCLUSIONS: Both treatment variants focusing on the transdiagnostic exposure-based violation of threat beliefs were effective in reducing symptom severity and disability in severe anxiety disorders. Temporally intensified exposure resulted in faster treatment response with substantial public health benefits and lower drop-out during the exposure phase, without higher relapse. Clinicians can expect better or at least comparable outcomes when delivering exposure in a temporally intensified manner.

Transfer of exposure therapy effects to a threat context not considered during treatment in patients with panic disorder and agoraphobia: Implications for potential mechanisms of change.

Further developments of exposure-based therapy (EBT) require more knowledge about transfer of treatment to non-trained everyday contexts. However, little is known about transfer effects of EBT. Using a standardized EBT protocol in 275 patients with panic disorder and agoraphobia we investigated the transfer of EBT to a highly standardized context during a Behavioral Avoidance Test (BAT; being entrapped in a small and dark test chamber) and not part of the exposure sessions. Patients of a treatment group underwent the BATs before treatment (t1), after a preparatory treatment phase (t2), and after an agoraphobic exposure phase (t3) and were compared with wait-list control patients, who repeated BAT assessments across the same time period. We found stronger reductions in avoidance behavior, reported fear, and autonomic arousal during the BAT from t1 to t3 in the treatment group patients who were anxious during t1 relative to the anxious but untreated patients. Fear reduction was related to treatment outcome indicating the contribution of transfer effects to successful EBT. Interestingly, reduction varied for different fear response systems suggesting different processes to may be involved in transfer effects. Importantly, final BAT assessment still evoked residual fear in the treatment group as compared to BAT non-anxious control patients, suggesting limited transfer effects - one possible reason for the return of symptoms in new situations.

Vagal control of the heart decreases during increasing imminence of interoceptive threat in patients with panic disorder and agoraphobia.

Theoretically, panic disorder and agoraphobia pathology can be conceptualized as a cascade of dynamically changing defensive responses to threat cues from inside the body. Guided by this trans-diagnostic model we tested the interaction between defensive activation and vagal control as a marker of prefrontal inhibition of subcortical defensive activation. We investigated ultra-short-term changes of vagally controlled high frequency heart rate variability (HRV) during a standardized threat challenge (entrapment) in n = 232 patients with panic disorder and agoraphobia, and its interaction with various indices of defensive activation. We found a strong inverse relationship between HRV and heart rate during threat, which was stronger at the beginning of exposure. Patients with a strong increase in heart rate showed a deactivation of prefrontal vagal control while patients showing less heart rate acceleration showed an increase in vagal control. Moreover, vagal control collapsed in case of imminent threat, i.e., when body symptoms increase and seem to get out of control. In these cases of defensive action patients either fled from the situation or experienced a panic attack. Active avoidance, panic attacks, and increased sympathetic arousal are associated with an inability to maintain vagal control over the heart suggesting that teaching such regulation strategies during exposure treatment might be helpful to keep prefrontal control, particularly during the transition zone from post-encounter to circa strike defense.Trial Registration Number: ISRCTN80046034.

The Cooperative Revolution Reaches Clinical Psychology and Psychotherapy: An Example From Germany.

Background: Psychology is at the beginning of a cooperative revolution. Traditionally, psychological research has been conducted by individual labs, limiting its scope in clinical samples and promoting replication problems. Large-scale collaborations create new opportunities for highly powered studies in this resource-intensive research area. To present the current state of a Germany-wide platform for coordinating research across university outpatient clinics for psychotherapy. Method: Since 1999, over 50 such clinics were created in Germany. They represent a unique infrastructure for research, training, and clinical care. In 2013, a steering committee initiated a nationwide research platform for systematic coordination of research in these clinics (German abbreviation "KODAP"). Its main goal is to aggregate and analyze longitudinal treatment data - including patient, therapist, and treatment characteristics - across all participating clinics. Results: An initial survey (100% response rate) yielded recommendations for improved integration of data collection. Pilot data from 4,504 adult (16 clinics) and 568 child and adolescent patients (7 clinics) proved feasibility of data transfer and aggregation despite different data formats. Affective, neurotic, stress, and somatoform (adults) and anxiety and behavioral (children and adolescents) disorders were most frequent; comorbidity was high. Overcoming legal, methodological, and technical challenges, a common core assessment battery was developed, and data collection started in 2018. To date, 42 clinics have joined. Conclusions: KODAP shows that research collaboration across university outpatient clinics is feasible. Fulfilling the need for stronger cumulative and cooperative research in Clinical Psychology will contribute to better knowledge about mental health, a core challenge to modern societies.

A clinical effectiveness trial comparing ACT and CBT for inpatients with depressive and mixed mental disorders.

AbstractObjective: Meta-analyses show that Acceptance and Commitment Therapy (ACT) is an efficacious treatment for a wide range of mental health problems. However, few studies have examined the effectiveness of ACT in naturalistic inpatient settings and in direct comparison to Cognitive Behavior Therapy (CBT). The aim of this study was to investigate the effectiveness of ACT and CBT with regard to depression, general symptom strain and life satisfaction. Method: 177 inpatients in a psychiatric ward were included in the study and assigned to either ACT or CBT group intervention. All patients were assessed with the SCID-I interview and disorder-specific questionnaires as well as with a satisfaction with life scale. To control for confounding variables, amongst others, treatment integrity was evaluated. Results: Both the ACT and CBT intervention showed a large, statistically significant and stable symptom reduction over six months across all outcomes. Both approaches led to small improvement in life satisfaction. With regards to depressive symptoms, more than half of the patients reliably recovered due to therapy. Conclusion: ACT and CBT were similarly effective in treating patients with depressive and other mental disorders in a routine clinical setting. ACT is a viable alternative to CBT for treating inpatients.

Genome-wide association study of panic disorder reveals genetic overlap with neuroticism and depression.

Panic disorder (PD) has a lifetime prevalence of 2-4% and heritability estimates of 40%. The contributory genetic variants remain largely unknown, with few and inconsistent loci having been reported. The present report describes the largest genome-wide association study (GWAS) of PD to date comprising genome-wide genotype data of 2248 clinically well-characterized PD patients and 7992 ethnically matched controls. The samples originated from four European countries (Denmark, Estonia, Germany, and Sweden). Standard GWAS quality control procedures were conducted on each individual dataset, and imputation was performed using the 1000 Genomes Project reference panel. A meta-analysis was then performed using the Ricopili pipeline. No genome-wide significant locus was identified. Leave-one-out analyses generated highly significant polygenic risk scores (PRS) (explained variance of up to 2.6%). Linkage disequilibrium (LD) score regression analysis of the GWAS data showed that the estimated heritability for PD was 28.0-34.2%. After correction for multiple testing, a significant genetic correlation was found between PD and major depressive disorder, depressive symptoms, and neuroticism. A total of 255 single-nucleotide polymorphisms (SNPs) with p < 1 × 10-4 were followed up in an independent sample of 2408 PD patients and 228,470 controls from Denmark, Iceland and the Netherlands. In the combined analysis, SNP rs144783209 showed the strongest association with PD (pcomb = 3.10 × 10-7). Sign tests revealed a significant enrichment of SNPs with a discovery p-value of <0.0001 in the combined follow up cohort (p = 0.048). The present integrative analysis represents a major step towards the elucidation of the genetic susceptibility to PD.

Hair cortisol moderates the association between obstetric complications and child wellbeing.

Obstetric complications (OC) may have implications for later health outcomes. However, there is a lack of research examining the association between OC and behavior problems or quality of life (HRQoL). We aimed to close this gap and further investigate functioning of the hypothalamus-pituitary-adrenal (HPA)-axis as a potential physiological vulnerability moderating the association between OC and behavior problems and HRQoL. We investigated 232 mothers and their five to 12-year-old children. Presence of OC during the pre-, peri-, and postnatal phases was determined by interviewing mothers. Children's behavior problems (CBCL, TRF) and HRQoL (Kidscreen rated by mothers and children) were assessed. Children gave 3 cm strands of hair for analysis of hair cortisol (HC). Structural equation modeling analyses with a latent variable of child outcome ("distress"), OC as predictor and HC as a potential moderator were conducted. OC significantly predicted distress (ß = .33, p < .01). The model showed a good fit to the data: χ2(14)=15.66, p < .33, CFI=.99, TLI=.99, RMSEA=.02, 90 %CI [.00, .06], SRMR=.04. In addition, HC moderated the association between OC and distress (ß=-.32, p < .01). The moderation model also showed a good fit: χ2(14) =7.13, p = .93, CFI=1.00, TLI=1.06, RMSEA=.00, 90 %CI [.00, .02], SRMR=.03. Results indicated that the association between OC and distress was significant only when children had low HC-levels. This was also the case for both externalizing and internalizing behavior problems. Our results underline the notion of OC as a risk factor for child behavior problems and wellbeing and point to an important role of the children's physiological set-up such as HPA-functioning.

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: A Randomized Clinical Trial.

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.

Life within a limited radius: Investigating activity space in women with a history of child abuse using global positioning system tracking.

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.
