RESUMO
BACKGROUND: Child maltreatment is a broadly confirmed risk factor for mental and physical illness. Some psychological treatments specifically target mental health conditions associated with child maltreatment. For example, the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) focuses on maladaptive interpersonal behaviours in chronic depression. However, how the assessment of child maltreatment could inform personalised treatment is unclear. We used data from a previously published clinical trial to investigate whether a pre-established child maltreatment clustering approach predicts differential outcomes after CBASP versus non-specific supportive psychotherapy in patients with early-onset chronic depression. METHODS: We did a cluster analysis of data from a previous randomised controlled trial of unmedicated adult outpatients with early-onset chronic depression who were treated at eight university clinics and psychological institutes in Germany with 32 sessions of CBASP or non-specific supportive psychotherapy. Participants were eligible for the original trial if they were aged 18-65 years; had major depressive disorder (MDD) with an early onset and duration of at least 2 years, current MDD superimposed on a pre-existing dysthymic disorder, or recurrent MDD with incomplete remission between episodes as defined by DSM-IV; and had a score of at least 20 points on the 24-item Hamilton Rating Scale for Depression (HRSD-24). Participants were included in the current study if they had completed the short form of the Childhood Trauma Questionnaire (CTQ) at trial baseline. We used an agglomerative hierarchical clustering approach to derive child maltreatment clusters from individual patterns across the five domains of the CTQ. We used linear mixed models to investigate whether clustering could predict differential clinical outcomes (change in symptom severity on the HRSD-24) up to 2 years after treatment onset. People with lived experience were involved in the current study. FINDINGS: 253 patients (129 [51%] treated with CBASP and 124 [49%] with supportive psychotherapy) had complete CTQ records and were included in the analysis. 169 (67%) participants were women, 84 (33%) were men, and the mean age was 45·9 years (SD 11·7). We identified seven child maltreatment clusters and found significant differences in treatment effects of CBASP and supportive psychotherapy between the clusters (F(6,948·76)=2·47; p=0·023); differences were maintained over the 2-year follow-up. CBASP was superior in distinct clusters of co-occurring child maltreatment: predominant emotional neglect (change in ß -6·02 [95% CI -11·9 to -0·13]; Cohen's d=-0·98 [95% CI -1·94 to -0·02]; p=0·045), predominant emotional neglect and abuse (-6·39 [-10·22 to -2·56]; -1·04 [-1·67 to -0·42]; p=0·0011), and emotional neglect and emotional and physical abuse (-9·41 [-15·91 to -2·91]; -1·54 [-2·6 to -0·47]; p=0·0046). INTERPRETATION: CTQ-based cluster analysis can facilitate identification of patients with early-onset chronic depression who would specifically benefit from CBASP. Child maltreatment clusters could be implemented in clinical assessments and serve to develop and personalise trauma-informed care in mental health.

INTRODUCTION: In the treatment of borderline personality disorder (BPD), there is empirical support for both dialectical behavior therapy (DBT) and schema therapy (ST); these treatments have never been compared directly. This study examines whether either of them is more effective than the other in treating patients with BPD. METHODS: In this randomized, parallel-group, rater-blind clinical trial, outpatients aged between 18 and 65 years with a primary diagnosis of BPD were recruited in a tertiary outpatient treatment center (Lübeck, Germany). Participants were randomized to DBT or ST with one individual and one group session per week over 1.5 years. The primary outcome was the BPD symptom severity assessed with the mean score of the Borderline Personality Disorder Severity Index at 1-year naturalistic follow-up. RESULTS: Between November 26, 2014, and December 14, 2018, we enrolled 164 patients (mean age = 33.7 [SD = 10.61] years). Of these, 81 (49.4%) were treated with ST and 83 (50.6%) with DBT, overall, 130 (79.3%) were female. Intention-to-treat analysis with generalized linear mixed models did not show a significant difference at 1-year naturalistic follow-up between DBT and ST for the BPDSI total score (mean difference 3.32 [95% CI: -0.58-7.22], p = 0.094, d = -24 [-0.69; 0.20]) with lower scores for DBT. Pre-to-follow-up effect sizes were large in both groups (DBT: d = 2.45 [1.88-3.02], ST: d = 1.78 [1.26-2.29]). CONCLUSION: Patients in both treatment groups showed substantial improvements indicating that even severely affected patients with BPD and various comorbid disorders can be treated successfully with DBT and ST. An additional non-inferiority trial is needed to show if both treatments are equally effective. The trial was retrospectively registered on the German Clinical Trials Register, DRKS00011534 without protocol changes.
RESUMO
BACKGROUND: The effectiveness of psychological interventions is undisputed. But while in other fields of health care the safety of interventions is studied alongside effectiveness, adverse events (AEs) have only recently been assessed in clinical studies of psychological interventions. This critical review summarizes the definition, assessment and current research status of AEs of psychological interventions. SUMMARY: AEs are defined as any untoward event or unfavorable change that occurs in the course of a psychological intervention. AEs that are caused by the intervention can be classified into side effects of correctly applied treatment, malpractice (i.e., incorrectly applied treatment) and unethical conduct (e.g., sexual abuse). Ideally, they are assessed by independent raters or alternatively by self-report questionnaires that should also cover serious adverse events (SAEs, e.g., suicide attempts or self-injurious behaviors). About 1 to 2 in 3 patients report at least 1 AE and results of meta-analyses suggest that treatments might differ in frequency and/or severity of AE and in treatment acceptability (measured as dropout rates). KEY MESSAGES: Measures of AEs and SAEs as well as more nuanced descriptions of dropout should be included in all clinical studies of psychological interventions. If this happens, we might learn that psychological interventions differ with respect to AEs, SAEs and acceptability. As many psychological interventions are about equally effective, they might one day be chosen based on differences in their safety profile rather than their differential effectiveness. Ideally, reducing AEs might also lead to more effective interventions.
RESUMO
Web-based interventions can be effective in treating depressive symptoms. Patients with risk not responding to treatment have been identified by early change patterns. This study aims to examine whether early changes are superior to baseline parameters in predicting long-term outcome. In a randomized clinical trial with 409 individuals experiencing mild to moderate depressive symptoms using the web-based intervention deprexis, three latent classes were identified (early response after registration, early response after screening and early deterioration) based on early change in the first four weeks of the intervention. Baseline variables and these classes were included in a Stepwise Cox Proportional Hazard Multiple Regression to identify predictors associated with the onset of remission over 36-months. Early change class was a significant predictor of remission over 36 months. Compared to early deterioration after screening, both early response after registration and after screening were associated with a higher likelihood of remission. In sensitivity and secondary analyses, only change class consistently emerged as a predictor of long-term outcome. Early improvement in depression symptoms predicted long-term outcome and those showing early improvement had a higher likelihood of long-term remission. These findings suggest that early changes might be a robust predictor for long-term outcome beyond baseline parameters.
RESUMO
OBJECTIVE: We evaluated differential treatment effects on specific symptoms and their mediators for Cognitive Behavioral Analysis System of Psychotherapy (CBASP) and Supportive Psychotherapy (SP) in persistently depressed patients. METHOD: We conducted a Bayesian mediation network intervention analysis with data from a randomized controlled trial comparing CBASP and SP. Three networks were calculated to investigate (1) differential treatment effects on specific symptoms, (2) differential treatment effects on the potential mediators interpersonal problems and social functioning, and (3) associations between change in symptoms and change in the potential mediators. RESULTS: First, we found no evidence that CBASP more strongly improves most depressive symptoms specifically, except minimal evidence of symptom-specific effects on sleeping problems and self-esteem. Second, no and minimal evidence for differential treatment effects on interpersonal problems and social functioning was shown, respectively. Third, interpersonal problems and social functioning were strongly related to depressive symptoms. CONCLUSION: While CBASP showed superior treatment effects for overall symptom severity, this treatment might not be superior in improving specific symptoms and the potential mediators interpersonal problems and social functioning. Still, interpersonal problems and social functioning seem to play an important role for depression symptoms. Future research needs to further investigate potential working mechanisms of CBASP.Trial registration: ClinicalTrials.gov identifier: NCT00970437.
RESUMO
BACKGROUND: Internet-based interventions (IBIs) for the treatment of depression have been found to have positive effects in international meta-analyses; however, it is unclear whether these effects also extend to IBIs specifically available in Germany. The aim of this meta-analysis was to estimate the immediate effects and the long-term effects of IBIs available in Germany free of charge or available on prescription and covered by the public health insurances as so-called digital health applications (DiGAs) and to compare the efficacy of DiGAs and freely available IBIs. METHOD: A systematic literature search and random-effects meta-analysis were performed (preregistration: INPLASY202250070). Randomized controlled trials (RCTs) of IBIs freely available in Germany or as DiGA in adults with elevated depressive symptoms were compared with active and inactive controls available at the time of the survey in May 2022. RESULTS: A total of six interventions were identified: COGITO, deprexis, iFightDepression, moodgym, Novego, and Selfapy. The pooled effect size of a total of 28 studies with 13,413 participants corresponded to an effect of Cohen's dâ¯= 0.42, (95% confidence interval, CI: 0.31-0.54, I2â¯= 81%). The analysis of long-term effects showed a smaller effect size of dâ¯= 0.29, (95% CI: 0.21-0.37, I2â¯= 22%, Nâ¯= 10). Subgroup analyses indicated a possible superiority of the three interventions listed in the DiGA directory (dâ¯= 0.56, 95% CI: 0.38-0.74, I2â¯= 83%, Nâ¯= 15) compared to the three freely available IBIs (dâ¯= 0.24, 95% CI: 0.14-0.33, I2â¯= 44%, Nâ¯= 13, pâ¯= 0.002). CONCLUSION: The IBIs for depressive disorders available in Germany are effective and can therefore be used in the treatment of people with a depressive disorder; however, it is possible that not all interventions are equally effective.

INTRODUCTION: New digital treatment formats may reduce barriers to treatment for individuals with suicidal ideation. This study aimed to investigate the feasibility of a remote blended care programme for this population, defined as acceptability, demand, practicality, adaptation, indications of efficacy and safety. METHODS: We conducted a mixed-methods single-arm trial for proof-of-concept. Participants were eligible if they were at least 18 years old, had sufficient German proficiency, a Beck Scale for Suicidal Ideation score ≥2, internet access and lived near the outpatient clinic. The treatment consisted of 12 sessions of cognitive-behavioural videotherapy combined with online modules over 6 weeks. RESULTS: We included 10 participants. All patients were satisfied with the treatment; most patients (80%) reported unpleasant memories resurfacing. All patients completed all therapy sessions and a mean of 13.7 modules (SD = 5.7); three patients switched to face-to-face treatment, in one case due to safety concerns. All patients and most therapists (83.3%) found the treatment overall practicable. Most patients (66.7%) and therapists (66.7%) considered remote treatment equivalent to face-to-face therapy. There were no serious adverse events. CONCLUSION: While promising, the results suggest changes to the programme might be needed, particularly for patients' safety. A controlled feasibility trial should investigate temporary deteriorations.
RESUMO
Importance: Conceptualizing mental disorders as latent entities has been challenged by the network theory of mental disorders, which states that psychological problems are constituted by a network of mutually interacting symptoms. While the implications of the network approach for planning and evaluating treatments have been intensively discussed, empirical support for the claims of the network theory regarding treatment effects is lacking. Objective: To assess the extent to which specific hypotheses derived from the network theory regarding the (interindividual) changeability of symptom dynamics in response to treatment align with empirical data. Design, Setting, and Participants: This secondary analysis entails data from a multisite randomized clinical trial, in which 254 patients with chronic depression reported on their depressive symptoms at every treatment session. Data collection was conducted between March 5, 2010, and October 14, 2013, and this analysis was conducted between November 1, 2021, and May 31, 2022. Intervention: Thirty-two sessions of either disorder-specific or nonspecific psychotherapy for chronic depression. Main Outcomes and Measures: Longitudinal associations of depressive symptoms with each other and change of these associations through treatment estimated by a time-varying longitudinal network model. Results: In a sample of 254 participants (166 [65.4%] women; mean [SD] age, 44.9 [11.9] years), symptom interactions changed through treatment, and this change varied across treatments and individuals. The mean absolute (ie, valence-ignorant) strength of symptom interactions (logarithmic odds ratio scale) increased from 0.40 (95% CI, 0.36-0.44) to 0.60 (95% CI, 0.52-0.70) during nonspecific psychotherapy and to 0.56 (95% CI, 0.48-0.64) during disorder-specific psychotherapy. In contrast, the mean raw (ie, valence-sensitive) strength of symptom interactions decreased from 0.32 (95% CI, 0.28-0.36) to 0.26 (95% CI, 0.20-0.32) and to 0.09 (95% CI, 0.02-0.16), respectively. Changing symptom severity could be explained to a large extent by symptom interactions. Conclusions and Relevance: These findings suggest that specific treatment-related hypotheses of the network theory align well with empirical data. Conceptualizing mental disorders as symptom networks and treatments as measures that aim to change these networks is expected to give further insights into the working mechanisms of mental health treatments, leading to the improvement of current and the development of new treatments.

INTRODUCTION: Major depressive disorder (MDD) is a highly prevalent and disabling disorder. This study examines two psychotherapy methods for MDD, behavioral activation (BA), and metacognitive therapy (MCT), when applied as outpatient treatments to severely affected patients. METHODS: The study was conducted in a tertiary outpatient treatment center. Patients with a primary diagnosis of MDD (N = 122) were included in the intention-to-treat sample (55.7% female, mean age 41.9 years). Participants received one individual and one group session weekly for 6 months (M). Assessments took place at baseline, pretreatment, mid-treatment (3 M), post-treatment (6 M), and follow-up (12 M). The primary outcome was depressive symptomatology assessed by the Hamilton Rating Scale for Depression at 12 M follow-up. Secondary outcomes included general symptom severity, psychosocial functioning, and quality of life. RESULTS: Linear mixed models indicated a change in depressive symptoms (F(2, 83.495) = 12.253, p < 0.001) but no between-group effect (F(1, 97.352) = 0.183, p = 0.670). Within-group effect sizes were medium for MCT (post-treatment: d = 0.610; follow-up: d = 0.692) and small to medium for BA (post-treatment: d = 0.636, follow-up: d = 0.326). In secondary outcomes, there were improvements (p ≤ 0.040) with medium to large within-group effect sizes (d ≥ 0.501) but no between-group effects (p ≥ 0.304). Response and remission rates did not differ between conditions at follow-up (response MCT: 12.9%, BA: 13.3%, remission MCT: 9.7%, BA: 10.0%). The deterioration rate was lower in MCT than in BA (χ21 = 5.466, p = 0.019, NTT = 7.4). DISCUSSION: Both MCT and BA showed symptom reductions. Remission and response rates were lower than in previous studies, highlighting the need for further improvements in adapting/implementing treatments for severely affected patients with MDD.

BACKGROUND: Music performance anxiety (MPA) is an issue concerning musicians from all levels but is still a rather neglected topic in the education and employment of musicians. This study investigated the link between self-esteem, MPA, and depression within a German-speaking sample of musicians of different professions. The underlying question of this study was generated during psychotherapy treatment of musicians with depression and MPA. Thus, we investigated whether musicians with low self-esteem had MPA or depression. METHODS: An online questionnaire on self-esteem, performance anxiety, and depression was sent to a sample (n=295) of German musicians of different professions and levels of education. The assessment tools in the online questionnaire included the Rosenberg-Self-Esteem-Scale, the Kenny Music-Performance-Anxiety-Inventory, and the Beck-Depression-Inventory. RESULTS: Music students had a significantly lower self-esteem scores compared to employed professionals and amateurs and a higher MPA compared to employed musicians. Regression analyses showed a significant prediction of depression by self-esteem and MPA. Specifically, low self-esteem and the cognitive and behavioral aspects of MPA were significant predictors of depression. Partial mediation by MPA between self-esteem and depression was found. CONCLUSION: Low self-esteem and MPA could predict depression. The scores of the entire sample of musicians regarding their MPA and depression were higher than in the general German population. These results highlight the importance of education and removal of negativity regarding performance anxiety in order to improve psychotherapy methods and ensure musicians' health in general.

Although abnormal resting state connectivity within several brain networks has been repeatedly reported in depression, little is known about connectivity in patients with early onset chronic depression. We compared resting state connectivity in a homogenous sample of 32 unmedicated patients with early onset chronic depression and 40 healthy control participants in a seed-to-voxel-analysis. According to previous meta-analyses on resting state connectivity in depression, 12 regions implicated in default mode, limbic, frontoparietal and ventral attention networks were chosen as seeds. We also investigated associations between connectivity values and severity of depression. Patients with chronic depression exhibited stronger connectivity between precuneus and right pre-supplementary motor area than healthy control participants, possibly reflecting aberrant information processing and emotion regulation deficits in depression. Higher depression severity scores (Hamilton Rating Scale for Depression) were strongly and selectively associated with weaker connectivity between the precuneus and the subcallosal anterior cingulate. Our findings correspond to results obtained in studies including both episodic and chronic depression. This suggests that there may be no strong differences between subtypes of depression regarding the seeds analyzed here. To further clarify this issue, future studies should directly compare patients with different courses of depression.

Web-based self-help programs for individuals with depressive symptoms are efficacious. Differences in effect sizes and adherence rates might be due to contextual factors. This randomized factorial trial investigated the effects of four potentially supportive contextual factors on outcome and adherence. Two factors were provided through human contact (guidance and a diagnostic interview), and two factors were provided without human contact (a motivational interviewing module and automated emails). We recruited 316 adults with mild to moderate depressive symptoms (Patient Health Questionnaire-9 score: 5-14). All participants received access to a problem-solving therapy program. Participants were randomized across the four experimental factors (present or absent), resulting in a 16-condition design. The primary outcome was depressive symptoms 10 weeks after baseline. The secondary outcome was program adherence. Overall, results showed significant symptom reduction for the primary depression measure (Cohen's d = 0.38-0.91). Guided participants showed significantly less severe symptoms of depression at post-treatment (d = 0.15) and higher treatment adherence (d = 0.53). At follow-up, these differences were no longer present. The remaining three factors did not influence primary outcome and adherence. These findings indicate that guidance leads to a faster reduction of depressive symptoms and higher treatment adherence.

Background Cognitive Behavioral Analysis System of Psychotherapy (CBASP) and Metacognitive Therapy (MCT) are effective for depression. CBASP might offer most benefit in patients reporting childhood emotional abuse (CEA). This needs to be confirmed in real-world settings and in comparisons with depression-specific psychotherapies. This study examines the moderating influence of CEA on the effectiveness of CBASP versus MCT. Methods In this observational study, we recruited patients treated with either CBASP or MCT in an intensive day treatment program for depression. CEA was assessed using the Childhood Trauma Questionnaire (CTQ). Patients reported symptoms weekly using the Quick Inventory of Depressive Symptoms (QIDS-SR). Mixed model analysis was run on the Intention to Treat dataset (ITT) using propensity matching to overcome baseline imbalances. Results A total of 141 patients were included in the analysis (MCT n = 78, CBASP n = 63). CEA moderated the treatment effect (time x CEA x treatment: ß = 0.03, SE = 0.01, p = 0.014). Post-hoc analyses revealed that CBASP was more effective than MCT in patients without CEA (time x treatment: ß = -0.01, SE = 0.007, p = .045). The difference between CBASP and MCT was not statistically significant for patients with CEA (ß = 0.015, SE = 0.008, p = .11). Limitations Because of non-random treatment allocation the differences between CBASP and MCT can be due to unobserved baseline imbalances. Conclusions Our findings suggest that in patients reporting CEA, CBASP might not offer additional benefits above other depression-specific psychotherapies. Public Health Significance Statements This study shows that, on average, individuals with depression benefit equally from CBASP and MCT under the conditions of routine practice. Yet, CBASP was more effective than MCT for those without childhood emotional abuse. If childhood emotional abuse was present, CBASP and MCT were equally effective.

Background: Perceived social support (PSS) is a crucial factor in physical and mental health. Previous studies found a negative association between childhood maltreatment (CM) and current PSS. Objective: In this paper, we investigate whether psychopathology moderates this association in a sample of patients with Depressive Disorder (DD) and Borderline Personality Disorder (BPD). Method: Sixty-nine patients with DD and 110 patients with BPD were recruited to inpatient/day clinic treatment programmes for either DD or BPD. All participants completed the Childhood Trauma Questionnaire (CTQ) and the Social Support Questionnaire (F-SozU). Our hypothesis was tested with a moderator analysis in a multiple linear regression model. Results: We found a significant interaction between diagnosis and CM for the CTQ total score and the emotional abuse subscale. Post hoc analyses revealed a significant negative correlation between CM and PSS only for patients suffering from BPD and not for patients with DD. Conclusion: Our results suggest that the negative association between CM and PSS might be more pronounced in certain patient groups, particularly patients with BPD.
Antecedentes: El apoyo social percibido (PSS en su sigla en inglés) es un factor crucial en la salud física y mental. Estudios previos encontraron una asociación negativa entre el maltrato infantil (MI) y el PSS actual.Objetivo: En este trabajo investigamos si la psicopatología modera esta asociación en una muestra de pacientes con trastorno depresivo (DD en su sigla en inglés) y trastorno límite de la personalidad (TLP).Método: Sesenta y nueve pacientes con DD y 110 pacientes con TLP fueron reclutados en programas de tratamiento clínico para pacientes de hospital diurno para DD o TLP. Todos los participantes completaron el cuestionario de trauma infantil (CTQ en su sigla en inglés) y el Cuestionario de apoyo social (F-SozU). Nuestra hipótesis fue probada con un análisis de moderador en un modelo de regresión lineal múltiple.Resultados: Encontramos una interacción significativa entre el diagnóstico y el MI para la puntuación total del CTQ y la subescala de abuso emocional. Los análisis post hoc revelaron una correlación negativa significativa entre MI y PSS solo para pacientes que padecían TLP y no para pacientes con DD.Conclusión: Nuestros resultados sugieren que la asociación negativa entre MI y PSS podría ser más pronunciada en ciertos grupos de pacientes, particularmente en pacientes con TLP.

BACKGROUND: Social anxiety disorder (SAD) is characterized by a marked fear of negative evaluation in social situations and significant impairments. Even with the most effective treatments, remission rates are around 50%. An important reason for the limited effectiveness of treatments is the lack of evidence-based explanation of how treatments work and what their active ingredients might be. An approach to unpack the active ingredients and mechanisms of treatment is the factorial design. OBJECTIVES: The study is a factorial trial aiming (1) to examine the main effects and interactions for the four main treatment components of internet-based cognitive-behavioral therapy (ICBT) for SAD (i.e., psychoeducation, cognitive restructuring, attentional training, and exposure) and (2) to examine whether and which change mechanisms mediate the relationship between treatment components and symptom reduction. METHODS: A total of 464 adults diagnosed with SAD will be randomized to one of 16 conditions containing combinations of the treatment components. The primary endpoint is SAD symptomatology at eight weeks. Secondary endpoints include symptoms of depression and anxiety, quality of life, and negative effects. Hypothesized change mechanisms are the increase of knowledge about SAD, the decrease of dysfunctional cognitions, the decrease of self-focused attention, and the decrease of avoidance and safety behaviors. DISCUSSION: A better understanding of the differential efficacy of treatment components and mechanisms of treatment underlying ICBT for SAD might inform clinicians and researchers to plan more potent and scalable treatments.

RESUMO
Background: This study explores the association of experienced dependency in psychotherapy as measured with the CDQ (Care Dependency Questionnaire) and treatment outcome in depression. Furthermore, the course of care dependency and differences in the CDQ scores depending on the received type of treatment, MCT (metacognitive therapy), or CBASP (cognitive behavioral analysis system of psychotherapy), were investigated. Methods: The study follows a prospective, parallel group observational design. Patients suffering from depression received an 8-week intensive day clinic program, which was either CBASP or MCT. The treatment decision was made by clinicians based on the presented symptomatology and with regard to the patients' preferences. The patients reported depressive symptoms with the QIDS-SR16 (Quick Inventory of Depressive Symptomatology) and levels of experienced care dependency with the German version of the CDQ on a weekly basis. Mixed-model analyses were run to account for the repeated-measures design. Results: One hundred patients were included in the analyses. Results indicate that higher levels of care dependency might predict a less favorable outcome of depressive symptomatology. Levels of care dependency as well as depressive symptoms decreased significantly over the course of treatment. There was no significant between-group difference in care dependency between the two treatment groups. Conclusion: The results suggest that care dependency might be associated with a worse treatment outcome in depressed patients. In general, care dependency seems to be a dynamic construct, as it is changing over time, while the levels of care dependency seem to be independent from the received type of treatment. Future research should continue investigating the mechanisms of care dependency in a randomized controlled design.

RESUMO
Background: Interpersonal skills deficits and dysfunctional metacognitive beliefs have been implicated in the etiology and maintenance of depression. This study aimed to investigate the association between changes in these skills deficits and change in depressive symptoms over the course of treatment with Cognitive Behavioral Analysis System of Psychotherapy (CBASP) and Metacognitive Therapy (MCT). Methods: In this prospective, parallel group observational study, data was collected at baseline and after 8 weeks of an intensive day clinic psychotherapy program. Based on a shared decision between patients and clinicians, patients received either CBASP or MCT. Ninety patients were included in the analyses (CBASP: age M = 38.7, 40.5% female, MCT: age M = 44.7, 43.3% female). Interpersonal deficits were assessed with the short-form of the Luebeck Questionnaire for Recording Preoperational Thinking (LQPT-SF) and the Impact Message Inventory (IMI-R). Metacognitive beliefs were assessed with the Metacognition Questionnaire-30 (MCQ-30). The Quick Inventory of Depressive Symptomatology (QIDS-SR16) was utilized to assess depressive symptoms. A regression analysis was conducted to assess variables associated with outcome. ANCOVAs were utilized to investigate whether improvement in skills deficits is dependent on type of treatment received. Results: Improvements in preoperational thinking and increases in friendly-dominant behavior were associated with change in depressive symptoms. There was no association between reductions in dysfunctional metacognitive beliefs and a decrease in depressive symptoms. While both treatment groups showed significant improvements in interpersonal and metacognitive skills, there was no significant between-group difference in the change scores for either of these skills. Conclusion: Our findings suggest that changes in interpersonal skills seem to be of particular relevance in the treatment of depression. These results have to be replicated in a randomized-controlled design before firm conclusions can be drawn.
RESUMO
IMPORTANCE: Borderline personality disorder (BPD) is a severe mental disorder that is often inadequately treated. OBJECTIVE: To determine if adding a self-management intervention to care as usual (CAU) is effective and safe. DESIGN: Randomised, controlled, rater-blind trial. Duration of treatment and assessments: 12 months. SETTING: Secondary care, recruited mainly via the internet. PARTICIPANTS: Patients with BPD and BPD Severity Index (BPDSI) of at least 15. INTERVENTIONS: CAU by treating psychiatrist and/or psychotherapist alone or adjunctive use of an internet-based self-management intervention that is based on schema therapy (priovi). MAIN OUTCOME MEASURE: Outcomes were assessed by trained raters. The primary outcome was change in BPDSI. The safety outcome was the number of serious adverse events (SAEs). The primary outcome time point was 12 months after randomisation. RESULTS: Of 383 participants assessed for eligibility, 204 were included (91.7% female, mean age: 32.4 years; 74% were in psychotherapy and 26% were in psychiatric treatment). The slope of BPDSI change did not differ significantly between groups from baseline to 12 months (F3,248= 1.857, p=0.14). At 12 months, the within-group effect sizes were d=1.38 (95% CI 1.07 to 1.68) for the intervention group and d=1.02 (95% CI 0.73 to 1.31) for the control group. The between-group effect size was d=0.27 (95% CI 0.00 to 0.55) in the intention-to-treat sample and d=0.39 (95% CI 0.09 to 0.68) for those who used the intervention for at least 3 hours (per-protocol sample). We found no significant differences in SAEs. CONCLUSIONS: We have not found a significant effect in favour of the intervention. This might be due to the unexpectedly large effect in the group receiving CAU by a psychiatrist and/or psychotherapist alone. TRIAL REGISTRATION: NCT03418142.

Background: Childhood maltreatment and difficulties in emotion regulation are common in patients with Borderline Personality Disorder (BPD) and Depressive Disorders (DD). Objective: This study examines differences between patients with BPD and patients with DD, regarding childhood maltreatment and difficulties in emotion regulation as well as the mediating effect of different aspects of emotion regulation deficits on the association between childhood maltreatment and BPD-symptoms. Method: A total of 305 participants, 177 with BPD and 128 with DD completed an assessment including the Childhood Trauma Questionnaire (CTQ), the Emotion Regulation Scale (DERS), the Brief Symptom Inventory (BSI), and the Structured Clinical Interview for DSM-IV (SCID). Data was analyzed using multiple analyses of variances and mediation analyses. Results: Patients with BPD reported more childhood maltreatment and more difficulties in emotion regulation than patients with DD. When general symptom severity, age, and gender were included in the analysis as covariates only group differences regarding 'impulse control difficulties' (F(1,299) = 38.97, p < .001, ηp2 = .115), 'limited access to emotion regulation strategies' (F(1,299) = 4.66, p = .032, ηp2 = .015), and 'lack of emotional clarity' (F(1,299) = 9.38, p = .002, ηp2 = .030) remained statistically significant. A mediation analysis, including above-mentioned covariates, indicated an association between emotional abuse and BPD-symptoms, which was mediated by difficulties in emotion regulation (indirect effect B = .012, 95% CI [.001; .031], R2 = .429). Subscale analyses revealed 'impulse control difficulties' as the aspect of difficulties in emotion regulation that has the greatest impact on this association (B = .021, 95% CI [.003; .045]). Conclusions: Patients with BPD display more childhood maltreatment and difficulties in emotion regulation than patients with DD. Difficulties in emotion regulation, especially difficulties in impulse control, seem to play an important role in the association between childhood emotional abuse and BPD-symptoms.
Antecedentes: El maltrato infantil y las dificultades en la regulación emocional son frecuentesw en pacientes con trastorno límite de personalidad (TLP) y pacientes con trastornos depresivos (TD).Objetivo: Este estudio examina las diferencias entre pacientes con TLP y pacientes con TD, en cuanto al maltrato infantil y las dificultades en la regulación de las emociones, así como el efecto mediador de diferentes aspectos de los déficits en la regulación de las emociones sobre la asociación entre el maltrato infantil y los síntomas del TLP.Método: Un total de 305 participantes, 177 pacientes con TLP y 128 pacientes con TD completaron una evaluación que incluyó el Cuestionario de Trauma Infantil (CTQ), la Escala de Regulación de las Emociones (DERS), el Inventario Breve de Síntomas (BSI) y la Entrevista Clínica Estructurada para DSM-IV (SCID). Los datos se analizaron mediante múltiples análisis de variaciones y análisis de mediación.Resultados: Los pacientes con TLP informaron más maltrato infantil y más dificultades en la regulación de las emociones que los pacientes con TD. Cuando la gravedad de los síntomas generales, la edad y el sexo se incluyeron en el análisis como covariables, solo las diferencias de grupo con respecto a las 'dificultades de control de impulsos' (F (1.299) = 38,97, p <.001, ηp2 = .115), 'acceso limitado a estrategias de regulación de las emociones '(F (1,299) = 4.66, p = .032, ηp2 = .015) y' falta de claridad emocional '(F (1,299) = 9.38, p = .002, ηp2 = .030) permanecieron estadísticamente significativas. Un análisis de mediación, incluidas las covariables antes mencionadas, indicó una asociación entre el abuso emocional y los síntomas del TLP, que fue mediada por dificultades en la regulación de las emociones (efecto indirecto B = .012, IC del 95% [.001; .031], R2 =. 429). Los análisis de subescalas revelaron "dificultades de control de impulsos" como el aspecto de las dificultades en la regulación de las emociones que tiene el mayor impacto en esta asociación (B = .021, IC del 95% [.003; .045]).Conclusiones: Los pacientes con TLP presentan más maltrato infantil y dificultades en la regulación de las emociones que los pacientes con TD. Las dificultades en la regulación de las emociones, especialmente las dificultades en el control de los impulsos, parecen jugar un papel importante en la asociación entre el abuso emocional infantil y los síntomas del TLP.
