Non-fear emotions in changes in posttraumatic stress disorder symptoms during treatment.

BACKGROUND AND OBJECTIVES: Posttraumatic stress disorder (PTSD) is not only associated with fear but also with other emotions. The present study aimed to examine if changes in shame, guilt, anger, and disgust predicted changes in PTSD symptoms during treatment, while also testing if PTSD symptoms, in turn, predicted changes in these emotions. METHODS: Participants (N = 155) with childhood-related PTSD received a maximum of 12 sessions of eye movement desensitization and reprocessing or imagery rescripting. The data was analyzed using Granger causality models across 12 treatment sessions and 6 assessment sessions (up until one year after the start of treatment). Differences between the two treatments were explored. RESULTS: Across treatment sessions, shame, and disgust showed a reciprocal relationship with PTSD symptoms, while changes in guilt preceded PTSD symptoms. Across assessments, anger was reciprocally related to PTSD, suggesting that anger might play a more important role in the longer term. LIMITATIONS: The individual emotion items were not yet validated, and the CAPS was not administered at all assessments. CONCLUSIONS: These findings partly differ from earlier studies that suggested a unidirectional relationship in which changes in emotions preceded changes in PTSD symptoms during treatment. This is in line with the idea that non-fear emotions do play an important role in the treatment of PTSD and constitute an important focus of treatment and further research.

The working mechanisms of imagery rescripting and eye movement desensitization and reprocessing: Findings from a randomised controlled trial.

We studied the mechanisms of eye movement desensitization and reprocessing (EMDR) and imagery rescripting (ImRs). We hypothesized that EMDR works via changes in memory vividness, that ImRs works via changes in encapsulated beliefs (EB), and that both treatments work via changes in memory distress. Patients (N = 155) with childhood-related posttraumatic stress disorder (Ch-PTSD) received 12 sessions of EMDR or ImRs. The vividness, distress, and EB related to the index trauma were measured with the Imagery Interview. PTSD severity was assessed with the Impact of Events Scale-Revised and the Clinician-Administered PTSD Scale for DSM-5. We conducted mixed regressions and Granger causality analyses. EMDR led to initially stronger changes in all predictors, but only for distress this was retained until the last assessment. No evidence for vividness as a predictive variable was found. However, changes in distress and EB predicted changes in PTSD severity during ImRs. These findings partially support the hypothesized mechanisms of ImRs, while no support was found for the hypothesized mechanisms of EMDR. Differences in the timing of addressing the index trauma during treatment and the timing of assessments could have influenced the findings. This study provides insight into the relative effectiveness and working mechanisms of these treatments.

Childhood maltreatment and adulthood victimization: An evidence-based model.

There is ample evidence showing that childhood maltreatment increases two to three fold the risk of victimization in adulthood. Various risk factors, including posttraumatic stress disorder (PTSD) symptoms, dissociation, self-blame, and alcohol abuse are related to revictimization. Although previous research examined associations between risk factors for revictimization, the evidence is limited and the proposed models mostly include a handful of risk factors. Therefore, it is critical to investigate a more comprehensive model explaining the link between childhood maltreatment and adulthood (re)victimization. Accordingly, this study tested a data-driven theoretical path model consisting of 33 variables (and their associations) that could potentially enhance understanding of factors explaining revictimization. Cross-sectional data derived from a multi-wave study were used for this investigation. Participants (N = 2156, age mean = 19.94, SD = 2.89) were first-year female psychology students in the Netherlands and New Zealand, who responded to a battery of questionnaires and performed two computer tasks. The path model created by structural equation modelling using modification indices showed that peritraumatic dissociation, PTSD symptoms, trauma load, loneliness, and drug use were important mediators. Attachment styles, maladaptive schemas, meaning in life, and sex motives connected childhood maltreatment to adulthood victimization via other factors (i.e., PTSD symptoms, risky sex behavior, loneliness, emotion dysregulation, and sex motives). The model indicated that childhood maltreatment was associated with cognitive patterns (e.g., anxious attachment style), which in turn were associated with emotional factors (e.g., emotion dysregulation), and then with behavioral factors (e.g., risky sex behavior) resulting in revictimization. The findings of the study should be interpreted in the light of the limitations. In particular, the cross-sectional design of the study hinders us from ascertaining that the mediators preceded the outcome variable.

A systematic research review of collaborative assessment methods.

Collaborative assessment methods (CAMs) involve working with clients during all phases of the assessment process, from goal definition to interpretation of the testing results to the recommendations and conclusions. In this article, we define CAMs, provide clinical examples, and then meta-analyze the published literature to assess their effectiveness on distal treatment outcomes. Our meta-analytic results indicate that CAMs have positive effects on three outcome domains: a moderate effect on treatment processes, a small-to-moderate effect on personal growth, and a small effect on symptom reduction. There is little research evidence on the immediate, in-session effects of CAMs. We include diversity considerations, training implications. and therapeutic practices grounded in this research evidence.

Dropout from psychological treatment for borderline personality disorder: a multilevel survival meta-analysis.

BACKGROUND: Dropout from psychotherapy for borderline personality disorder (BPD) is a notorious problem. We investigated whether treatment, treatment format, treatment setting, substance use exclusion criteria, proportion males, mean age, country, and other variables influenced dropout. METHODS: From Pubmed, Embase, Cochrane, Psycinfo and other sources, 111 studies (159 treatment arms, N = 9100) of psychotherapy for non-forensic adult patients with BPD were included. Dropout per quarter during one year of treatment was analyzed on participant level with multilevel survival analysis, to deal with multiple predictors, nonconstant dropout chance over time, and censored data. Multiple imputation was used to estimate quarter of drop-out if unreported. Sensitivity analyses were done by excluding DBT-arms with deviating push-out rules. RESULTS: Dropout was highest in the first quarter of treatment. Schema therapy had the lowest dropout overall, and mentalization-based treatment in the first two quarters. Community treatment by experts had the highest dropout. Moreover, individual therapy had lowest dropout, group therapy highest, with combined formats in-between. Other variables such as age or substance-use exclusion criteria were not associated with dropout. CONCLUSION: The findings do not support claims that all treatments are equal, and indicate that efforts to reduce dropout should focus on early stages of treatment and on group treatment.

Direct and Indirect Exposure to Trauma, Posttraumatic Stress Disorder Symptoms, and Poor Subjective Sleep Quality in Patients with Substance Use Disorder.

Background: Despite the frequent co-occurrence of posttraumatic stress disorder and substance use disorder, screening for trauma exposure and posttraumatic stress disorder symptoms is not a routine practice in substance use disorder clinics. The aims of this study were to examine the prevalence of exposure to traumatic events, posttraumatic stress disorder symptoms, and subjective sleep quality in substance use disorder inpatients after detoxification. In addition, we analyzed associations of sociodemographics, direct and indirect exposure to traumatic events, and sleep quality with posttraumatic stress disorder symptom severity. Methods: Adults diagnosed with substance use disorder (n = 188; 25% women, mean age 46.6 ± 12.3 years) from 2 inpatient addiction clinics were assessed at approximately 4 days post-admission for age, gender, educational level, self-reported substance use, trauma exposure, general and posttraumatic stress disorder-specific subjective sleep quality, and posttraumatic stress disorder symptom severity. Correlates of posttraumatic stress disorder symptom severity were identified with linear regression analyses. Results: The prevalence of direct trauma exposure was high (89%), 51% of participants screened positive for posttraumatic stress disorder and 87% reported clinically significant poor sleep quality. Younger age, female gender, direct and indirect exposure to more traumatic events, and poor subjective sleep quality were associated with more severe posttraumatic stress disorder symptoms. Conclusion: Nearly all substance use disorder patients admitted for detoxification in our study had been directly or indirectly exposed to 1 or more traumatic events, and many reported posttraumatic stress disorder symptoms and poor sleep quality. Younger and female substance use disorder patients were at higher risk of posttraumatic stress disorder symptoms. Our results emphasize the need for systematic screening for direct and indirect trauma exposure, posttraumatic stress disorder symptoms, and poor sleep quality in patients admitted for clinical substance use disorder treatment.

Effectiveness of Psychological Treatments for Borderline Personality Disorder and Predictors of Treatment Outcomes: A Multivariate Multilevel Meta-Analysis of Data from All Design Types.

We examined the effectiveness of psychotherapies for adult Borderline Personality Disorder (BPD) in a multilevel meta-analysis, including all trial types (PROSPERO ID: CRD42020111351). We tested several predictors, including trial- and outcome type (continuous or dichotomous), setting, BPD symptom domain and mean age. We included 87 studies (N = 5881) from searches between 2013 and 2019 in four databases. We controlled for differing treatment lengths and a logarithmic relationship between treatment duration and effectiveness. Sensitivity analyses were conducted by excluding outliers and by prioritizing total scale scores when both subscale and total scores were reported. Schema Therapy, Mentalization-Based Treatment and reduced Dialectical Behavior Therapy were associated with higher effect sizes than average, and treatment-as-usual with lower effect sizes. General severity and affective instability showed the strongest improvement, dissociation, anger, impulsivity and suicidality/self-injury the least. Treatment effectiveness decreased as the age of participants increased. Dichotomous outcomes were associated to larger effects, and analyses based on last observation carried forward to smaller effects. Compared to the average, the highest reductions were found for certain specialized psychotherapies. All BPD domains improved, though not equally. These findings have a high generalizability. However, causal conclusions cannot be drawn, although the design type did not influence the results.

The impact of childhood maltreatment on the severity of childhood-related posttraumatic stress disorder in adults.

BACKGROUND: Childhood maltreatment is relatively common and is related to a range of negative consequences, such as Posttraumatic Stress Disorder (PTSD). There are indications that various maltreatment types are related to PTSD severity, although not all types, such as emotional abuse, meet the PTSD Criterion-A. OBJECTIVE: The aim of the present study was to examine the relationship between 5 types of childhood maltreatment (i.e., sexual, physical, and emotional abuse, and physical and emotional neglect) and the severity of adult PTSD and PTSD symptoms. PARTICIPANTS AND SETTING: Adult participants (N = 147) with Childhood-related PTSD (Ch-PTSD) recruited from clinical sites completed the Childhood Trauma Questionnaire-short form (CTQ-sf) and 2 PTSD measures: The Clinician Administered PTSD Scale for DSM-5 (CAPS-5) and the PTSD Checklist for DSM-5 (PCL-5). METHODS: Childhood maltreatment predictors and 2 covariates, age and gender, were analysed in multivariate multilevel models as participants were nested within sites. A model selection procedure, in which all combinations of predictors were examined, was used to select a final set of predictors. RESULTS: The results indicated that emotional abuse was the only trauma type that was significantly related to severity of PTSD and to the severity of specific PTSD symptom clusters (r between 0.130 and 0.338). The final models explained between 6.5% and 16.7% of the variance in PTSD severity. CONCLUSIONS: The findings suggest that emotional abuse plays a more important role in Ch-PTSD than hitherto assumed, and that treatment should not neglect processing of childhood emotional abuse.

Comparative efficacy of imagery rehearsal therapy and prazosin in the treatment of trauma-related nightmares in adults: A meta-analysis of randomized controlled trials.

Pharmacological treatment with prazosin and psychological treatment with imagery rehearsal therapy (IRT) are the two main treatments of posttraumatic nightmares. The American Academy of Sleep Medicine task force recently listed IRT as the recommended treatment for trauma-related nightmares and changed the recommendation of prazosin to 'may be used'. This new recommendation was based on a single prazosin trial and not on a meta-analytic review of all available trials. The current meta-analysis aims to fill this gap in the literature. Eight studies on IRT and seven studies on prazosin (N = 1.078) were analyzed based on the random effects model. Relative to control groups, prazosin had a moderate to large effect on nightmare frequency (g = 0.61), posttraumatic stress symptoms (g = 0.81), and sleep quality (g = 0.85). IRT showed small to moderate effects on nightmare frequency (g = 0.51), posttraumatic symptoms (g = 0.31), and sleep quality (g = 0.51). No significant differences in effect were observed between prazosin and IRT on any of these outcomes (all p's > 0.10). It is concluded that downgrading the recommendation of prazosin may be a premature decision and that the aggregated results in this meta-analysis clearly show efficacy of both treatments.

The efficacy of a single imaginal exposure-writing assignment in reducing posttraumatic stress and depressive symptoms: A pilot study.

OBJECTIVE: This online study examined the effects of a single imaginal exposure-writing assignment on posttraumatic stress (PTS) and comorbid depressive symptoms. METHOD: Forty-six participants with PTS were allocated to either a single imaginal exposure-writing assignment, a nontrauma writing assignment, or to a nonwriting control condition, and were reassessed 2 and 5 weeks after baseline. Of the 49 participants, 36 were female, with an average age of 23. Participation was conducted through Qualtrics. Effects were assessed with the Posttraumatic Diagnostic Scale (PDS) and the Beck Depression Inventory-II (BDI-II). RESULTS: PTS and depressive symptoms decreased over time regardless of the study condition. CONCLUSIONS: We found no support for the efficacy of a single imaginal exposure-writing assignment in reducing PTS or comorbid depressive symptoms. Suggestions are given for future studies that attempt to identify a minimal dose of imaginal exposure writing for PTS.

Efficacy of a Mindfulness-Based Mobile Application: a Randomized Waiting-List Controlled Trial.

Although several hundreds of apps are available that (cl)aim to promote mindfulness, only a few methodologically sound studies have evaluated the efficacy of these apps. This randomized waiting-list controlled trial therefore tested the hypothesis that one such app (the VGZ Mindfulness Coach) can achieve immediate and long-term improvements of mindfulness, quality of life, general psychiatric symptoms, and self-actualization. One hundred ninety-one experimental participants received the VGZ Mindfulness Coach, which offers 40 mindfulness exercises and background information about mindfulness without any form of therapeutic guidance. Compared to 186 control participants, they reported large (Cohen's d = 0.77) and statistically significant increases of mindfulness after 8 weeks and small-to-medium increases of the Observing, Describing, Acting with awareness, Nonjudging, and Nonreactivity mindfulness facets as measured with the Five Facet Mindfulness Questionnaire (Cohen's d = 0.66, 0.26, 0.49, 0.34, and 0.43, respectively). Also, there were large decreases of general psychiatric symptoms (GHQ-12; Cohen's d = -0.68) and moderate increases of psychological, social, and environmental quality of life (WHOQOL-BREF; Cohen's d = 0.38, 0.38, and 0.36, respectively). Except for social quality of life, these gains were maintained for at least 3 months. We conclude that it is possible to achieve durable positive effects on mindfulness, general psychiatric symptoms, and several aspects of quality of life at low costs with smartphone apps for mindfulness such as the VGZ Mindfulness Coach.

Paint it Black: Using Change-Point Analysis to Investigate Increasing Vulnerability to Depression towards the End of Vincent van Gogh's Life.

This study investigated whether Vincent van Gogh became increasingly self-focused-and thus vulnerable to depression-towards the end of his life, through a quantitative analysis of his written pronoun use over time. A change-point analysis was conducted on the time series formed by the pronoun use in Van Gogh's letters. We used time as a predictor to see whether there was evidence for increased self-focus towards the end of Van Gogh's life, and we compared this to the pattern in the letters written before his move to Arles. Specifically, we examined Van Gogh's use of first person singular pronouns (FPSP) and first person plural pronouns (FPPP) in the 415 letters he wrote while working as an artist before his move to Arles, and in the next 248 letters he wrote after his move to Arles until his death in Auvers-sur-Oise. During the latter period, Van Gogh's use of FPSP showed an annual increase of 0.68% (SE = 0.15, p < 0.001) and his use of FPPP showed an annual decrease of 0.23% (SE = 0.04, p < 0.001), indicating increasing self-focus and vulnerability to depression. This trend differed from Van Gogh's pronoun use in the former period (which showed no significant trend in FPSP, and an annual increase of FPPP of 0.03%, SE = 0.02, p = 0.04). This study suggests that Van Gogh's death was preceded by a gradually increasing self-focus and vulnerability to depression. It also illustrates how existing methods (i.e., quantitative linguistic analysis and change-point analysis) can be combined to study specific research questions in innovative ways.

Traumatic events and trauma-related psychopathology in former drug cartel soldiers in Rio de Janeiro: A pilot study.

This pilot study investigated the occurrence of traumatic events and trauma-related psychopathology in former drug cartel soldiers (FDCS) in Rio de Janeiro. Furthermore, the authors examined the relationship between the number of traumatic events and symptom severity, and compared symptom severity in perpetrators versus victims of traumatic events. They found high exposure rates to traumatic events, with 83.5% of the FDCS (n = 97) and 57.9% of the controls (n = 95) having experienced more than 5 events. FDCS had higher mean scores for trauma exposure, posttraumatic stress (PTS), depressive symptoms, and general mental health problems, compared to controls. More FDCS than controls satisfied DSM-IV symptom criteria for posttraumatic stress disorder (36.4% vs. 15.8%) and reported severe depressive symptoms (25.8% vs. 8.3%). The number of traumatic events was strongly related to PTS among FDCS (r = .48). Furthermore, more FDCS than controls (23.7% vs. 10.5%) identified themselves as a perpetrator of 1 or more traumatic events. Among FDCS, perpetrators reported more PTS than victims. It is concluded that being a (former) drug cartel soldier is associated with elevated trauma exposure and severe trauma-related psychopathology.

Comparison of DSM-IV and proposed ICD-11 formulations of PTSD among civilian survivors of war and war veterans.

The World Health Organization recently proposed a reformulation of posttraumatic stress disorder (PTSD) for the 11(th) edition of the International Classification of Diseases (ICD-11), employing only 6 symptoms. The aim of this study was to investigate the impact of this reformulation of PTSD as compared to criteria according to Diagnostic and Statistical Manual of Mental Disorders (4th ed., DSM-IV; American Psychiatric Association, 1994) on the prevalence of current PTSD as well as comorbid major depressive episode and anxiety disorders other than PTSD. Study 1 involved previously collected interviews with 560 Kosovar civilian war survivors; Study 2 employed a previously collected sample of 142 British war veterans. Results revealed no change in the diagnostic status under the criteria proposed for ICD-11 in 87.5% of civilian war survivors and 91.5% of war veterans. Participants who only met the newly proposed criteria showed lower rates of comorbid major depressive episode than participants who only met DSM-IV criteria (13.6% vs. 43.8% respectively). Rates of comorbid anxiety disorders did not significantly differ between participants who lost or gained a PTSD diagnosis under the proposed criteria.

The efficacy of metacognitive therapy for anxiety and depression: a meta-analytic review.

BACKGROUND: Metacognitive therapy (MCT) is a relatively new approach to treating mental disorders. The aim of the current meta-analysis was to examine the efficacy of MCT in patients with mental disorders. METHOD: A comprehensive literature search revealed 16 published as well as unpublished studies on the efficacy of MCT, of which nine were controlled trials. These studies report on 384 participants suffering from anxiety or depression. Treatment efficacy was examined using a random effects model. RESULTS: On primary outcome measures the aggregate within-group pre- to posttreatment and pretreatment to follow-up effect sizes for MCT were large (Hedges' g = 2.00 and 1.65, respectively). Within-group pre- to posttreatment changes in metacognitions were also large (Hedges' g = 1.18) and maintained at follow-up (Hedges' g = 1.31). Across the controlled trials, MCT was significantly more effective than both waitlist control groups (between-group Hedges' g = 1.81) as well as cognitive behavior therapy (CBT; between-group Hedges' g = 0.97). CONCLUSIONS: Results suggest that MCT is effective in treating disorders of anxiety and depression and is superior compared to waitlist control groups and CBT, although the latter finding should be interpreted with caution. The implications of these findings are limited by small sample sizes and few active control conditions. Future studies should include larger sample sizes and also include comparisons of MCT with other empirically supported therapies.

Writing therapy for posttraumatic stress: a meta-analysis.

BACKGROUND: Face-to-face psychological treatments have difficulty meeting today's growing mental health needs. For the highly prevalent posttraumatic stress (PTS) conditions, accumulating evidence suggests that writing therapy may constitute an efficient treatment modality, especially when administered through the Internet. We therefore conducted a meta-analysis to investigate the efficacy of writing therapies for PTS and comorbid depressive symptoms. METHODS: The literature was searched using several structured and unstructured strategies, including key word searches of the PubMed, Web of Science, PsycINFO, and PILOTS databases. Six studies met eligibility criteria and were included in the analyses. These studies included a total of 633 participants, of which 304 were assigned to writing therapy. RESULTS: Across 5 direct comparisons of writing therapy to waiting-list control, writing therapy resulted in significant and substantial short-term reductions in PTS and comorbid depressive symptoms. There was no difference in efficacy between writing therapy and trauma-focused cognitive behavioral therapy, but we caution that this finding was based on only 2 direct comparisons. CONCLUSIONS: Writing therapy is an evidence-based treatment for PTS, and constitutes a useful treatment alternative for patients who do not respond to other evidence-based treatments. Internet adaptations of writing therapy for PTS may be especially useful for reaching trauma survivors in need of evidence-based mental health care who live in remote areas or who prefer to retain their anonymity.

Dealing with man-made trauma: the relationship between coping style, posttraumatic stress, and quality of life in resettled, traumatized refugees in the Netherlands.

This study investigated the relationship between coping style, posttraumatic stress disorder (PTSD) symptoms, and quality of life in traumatized refugees (N = 335). Participants had resettled in the Netherlands on average 13 years prior and were referred to a Dutch clinic for the treatment of posttraumatic psychopathology resulting from persecution, war, and violence. The majority (85%) of the research sample met diagnostic criteria for PTSD. Path analysis suggested a model in which PTSD symptoms (ß = -.61, p < .001), social support seeking (ß = .12, p < .05), and emotion-focused coping (ß = .13, p < .01) have a direct effect on quality of life. The role of avoidant and problem-focused coping could be interpreted in 2 ways. Either these coping styles are influenced by PTSD severity and have no effect on quality of life, or these coping styles influence PTSD severity and therefore have an indirect effect on quality of life. Intervention strategies aimed at modifying coping strategies and decreasing PTSD symptoms could be important in improving the quality of life of traumatized refugees.
