Group psychotherapy for female adult survivors of interpersonal psychological trauma: a preliminary study in Scotland

Survival, Attachment, and Healing: An Evolutionary Lens on Interventions for Trauma-Related Dissociation

Purpose

Dissociation is a necessary part of our threat response system, common to all animal species, normally temporarily activated under conditions of extreme or inescapable threat. Pathological dissociation, however, continues to occur after the initial threat has passed, in response to reminders or inaccessibility of safety and security. Present across the spectrum of psychiatric diagnoses, recurrent dissociative symptoms are linked to severe trauma exposure, insecure attachment, treatment non-response, and maladaptive coping behaviors such as substance use, suicidality, and self-harm. However, empirical studies testing treatments specific to dissociative processes remain scarce. This narrative review summarizes existing studies and provides theoretical, neurobiological, and evolutionary perspectives on dissociative processes and treatments for pathological dissociation.

Methods

A systematic search of five databases (MEDLINE, EMBASE, APA PsycINFO, CINAHL plus, Scopus) was conducted on April 13, 2023. Peer-reviewed clinical studies with adult participants, assessing intervention effects on dissociative symptoms, were included. Results were thematically analyzed and summarized.

Results

Sixty-nine studies were identified, mainly focused on posttraumatic stress disorder, trauma-exposed populations, and borderline personality disorder. Psychotherapy was studied in 72.5% of studies; other interventions included medications and neurostimulation. The majority reported positive outcomes, despite the heterogeneous spectrum of interventions. However, treatment of dissociative symptoms was the primary objective in only a minority.

Conclusion

Pathological dissociation is a complex phenomenon involving brain and body systems designed for perceiving and responding to severe threats, requiring an individualized approach. A literature is emerging regarding potentially evidence-based treatments to help those impacted by recurrent dissociative symptoms. When contextualized within a neurobiological and evolutionary perspective, these treatments can be understood as facilitating an internal and/or relational sense of safety, resulting in symptom reduction. Further studies are needed to explore effective treatments for dissociative symptoms.

Trends in outcomes used to measure the effectiveness of UK-based support interventions and services targeted at adults with experience of domestic and sexual violence and abuse: a scoping review

OBJECTIVES

In the UK, a range of support services and interventions are available to people who have experienced or perpetrated domestic and sexual violence and abuse (DSVA). However, it is currently not clear which outcomes and outcome measures are used to assess their effectiveness. The objective of this review is to summarise, map and identify trends in outcome measures in evaluations of DSVA services and interventions in the UK.

DESIGN

Scoping review.

DATA SOURCES

MEDLINE, EMBASE, PsycINFO, Social Policy and Practice, ASSIA, IBSS, Sociological abstracts and SSCI electronic databases were searched from inception until 21 June 2022. Grey literature sources were identified and searched.

ELIGIBILITY

We included randomised controlled trials, non-randomised comparative studies, pre-post studies and service evaluations, with at least one outcome relating to the effectiveness of the support intervention or service for people who have experienced and/or perpetrated DSVA. Outcomes had to be assessed at baseline and at least one more time point, or compared with a comparison group.

CHARTING METHODS

Outcome measures were extracted, iteratively thematically grouped into categories, domains and subdomains, and trends were explored.

RESULTS

80 studies reporting 87 DSVA interventions or services were included. A total of 426 outcome measures were extracted, of which 200 were used more than once. The most commonly reported outcome subdomain was DSVA perpetration. Cessation of abuse according to the Severity of Abuse Grid was the most common individual outcome. Analysis of temporal trends showed that the number of studies and outcomes used has increased since the 1990s.

CONCLUSIONS

Our findings highlight inconsistencies between studies in outcome measurement. The increase in the number of studies and variety of measures suggests that as evaluation of DSVA services and interventions matures, there is an increased need for a core of common, reliable metrics to aid comparability.

What are the Experiences of and Interventions for Adult Survivors of Childhood Sexual Abuse in South Asia? A Systematic Review and Narrative Synthesis

Adult survivors of childhood sexual abuse (CSA) may experience emotional, social, and psychological difficulties, heightened due to the interpersonal nature of harm. Despite the demonstrated effectiveness of trauma-focused treatments in the West, a culturally specific understanding of the needs of and treatments for survivors in South Asia is still in its infancy. The study aimed to systematically review research findings on the mental health impacts of CSA on adult survivors and current treatment approaches and their efficacy and acceptability in South Asia. Seven databases (Scopus, Ovid, CINAHL, ProQuest, EThOS, Google Scholar, and Dogpile) and five peer-reviewed South Asian journals were searched from inception until March 30, 2023. Searches included participants who were adult survivors of CSA of South Asian origin residing in South Asia. Studies on their mental health, different treatments, and the efficacy and acceptability of these treatments were included. Quality assessment tools were used to appraise the quality of included studies. The results were synthesized narratively. A total of 3,362 records were retrieved, and 24 articles were included in the final review. Twenty studies reported mental health impacts of CSA on adult survivors, four studies reported current treatments offered, and two studies were on recovery. However, no study focused on the efficacy or acceptability of the treatments being delivered. Even though the needs of adult CSA survivors in South Asia have been partly identified, there is very little research into the treatments for them.

A Scoping Review of the Trauma Recovery and Empowerment Model (TREM)

The link between interpersonal trauma and negative biopsychosocial outcomes has been well-documented. Integrated treatments that address trauma, mental health, and substance use among women with trauma histories have been found to be more effective than treatments that focus separately on these concerns. Since the early 2000s, the Trauma Recovery and Empowerment Model (TREM) has been described as a "promising" integrated trauma group therapy for women. Despite widespread recognition and implementation of TREM, its effectiveness has not been clearly established. The present scoping review is the first systematic effort to describe the extant literature on TREM and aims to provide an understanding of TREM's effectiveness by organizing and synthesizing the available empirical data. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews, a systematic search was conducted using PubMed, PsycINFO, SW Abstracts, Scopus, Embase, and Web of Science. Quantitative dissertation findings not published elsewhere and peer-reviewed journal articles published in English that reported outcomes from TREM intervention research with adult women were included. Twelve of the initial 385 publications identified met the inclusion criteria and reported data from nine studies. TREM demonstrated statistically significant effects on posttraumatic stress disorder, anxiety, psychological/psychosomatic distress, and substance use. A more limited set of findings suggests that TREM may also be associated with additional gains, including self-esteem, relationship power, social support, attachment, and spiritual well-being. Future research should replicate findings, use random assignment to groups, involve larger sample sizes and more representative samples, examine optimal duration, and identify components that facilitate change.

Measuring the Effects of the Shape Your Life Project on the Mental and Physical Health Outcomes of Survivors of Gender-Based Violence

Little is known regarding the types of physical activity interventions most effective in supporting the mental and physical health of woman-identified survivors of gender-based violence. This study measured the experiences of 56 participants who participated in a 14-week trauma-informed, noncontact boxing program once per week for 90 min. Participants completed measures of health-related outcomes including physical and mental health, quality of life, mastery, resilience, self-esteem, physical self-efficacy, social conflict, and financial strain at baseline, program midpoint, and program end. Analyses of variance showed significant improvements for all indicators measured except financial strain, demonstrating viability and effectiveness of this program.

A combined individual and group-based stabilization and skill training intervention versus treatment as usual for patients with long lasting posttraumatic reactions receiving outpatient treatment in specialized mental health care – a study protocol for a randomized controlled trial

Background

Suffering linked to previous interpersonal trauma is common among patients in mental health care. Diagnostic labels may vary, but the clinical picture is often characterized by long-lasting and complex psychological and somatic symptoms, subjective distress and reduced quality of health and life. A substantial proportion of patients do not recover after individual treatment in ordinary specialized mental healthcare settings, despite the proven usefulness of individual trauma-specific treatments. The therapeutic factors that arise in group settings, such as normalization, shame reduction and corrective relational experiences, may be particularly useful for trauma survivors. However, evidence in support of group treatment for trauma survivors is scarce. This study aims to test whether combining a novel group intervention to individual treatment is superior to conventional individual out-patient treatment in an ordinary community mental health hospital.

Methods

In a single-site, non-blinded, randomized controlled trial (RCT), the effect of a combined group-based stabilization and skill-training (SST) intervention added to individual treatment will be compared to conventional treatment (treatment as usual, TAU) alone. Participants (N = 160) with ongoing and long-lasting reactions related to known adverse life events from the past will be recruited among patients at general outpatient clinics in a community mental health centre at St. Olav’s University Hospital, Trondheim, Norway. Following baseline assessment and randomization, participants will complete follow-up measures at 4, 8, 13 and 19 months post-baseline. The primary outcome is personal recovery (The questionnaire about the process of recovery , QPR). Secondary outcomes include (1) self-reported symptoms of posttraumatic stress, general mental and somatic health symptoms, well-being, functional impairment and client satisfaction, (2) immunological and endocrine response measured in blood samples and (3) national registry data on occupational status, use of mental health services and pharmacological treatment. Additionally, mechanisms of change via posttraumatic cognitions will be examined.

Discussion

The addition of a group-based intervention to individual treatment for trauma survivors might prove to be an efficient way to meet the need of long-lasting high-intensity treatment in a large group of patients in mental health care, thereby reducing their suffering and increasing their psychosocial functioning.

Interventions for adults with a history of complex traumatic events: the INCiTE mixed-methods systematic review

BACKGROUND

People with a history of complex traumatic events typically experience trauma and stressor disorders and additional mental comorbidities. It is not known if existing evidence-based treatments are effective and acceptable for this group of people.

OBJECTIVE

To identify candidate psychological and non-pharmacological treatments for future research.

DESIGN

Mixed-methods systematic review.

PARTICIPANTS

Adults aged ≥ 18 years with a history of complex traumatic events.

INTERVENTIONS

Psychological interventions versus control or active control; pharmacological interventions versus placebo.

MAIN OUTCOME MEASURES

Post-traumatic stress disorder symptoms, common mental health problems and attrition.

DATA SOURCES

Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1937 onwards); Cochrane Central Register of Controlled Trials (CENTRAL) (from inception); EMBASE (1974 to 2017 week 16); International Pharmaceutical Abstracts (1970 onwards); MEDLINE and MEDLINE Epub Ahead of Print and In-Process & Other Non-Indexed Citations (1946 to present); Published International Literature on Traumatic Stress (PILOTS) (1987 onwards); PsycINFO (1806 to April week 2 2017); and Science Citation Index (1900 onwards). Searches were conducted between April and August 2017.

REVIEW METHODS

Eligible studies were singly screened and disagreements were resolved at consensus meetings. The risk of bias was assessed using the Cochrane risk-of-bias tool and a bespoke version of a quality appraisal checklist used by the National Institute for Health and Care Excellence. A meta-analysis was conducted across all populations for each intervention category and for population subgroups. Moderators of effectiveness were assessed using metaregression and a component network meta-analysis. A qualitative synthesis was undertaken to summarise the acceptability of interventions with the relevance of findings assessed by the GRADE-CERQual checklist.

RESULTS

One hundred and four randomised controlled trials and nine non-randomised controlled trials were included. For the qualitative acceptability review, 4324 records were identified and nine studies were included. The population subgroups were veterans, childhood sexual abuse victims, war affected, refugees and domestic violence victims. Psychological interventions were superior to the control post treatment for reducing post-traumatic stress disorder symptoms (standardised mean difference -0.90, 95% confidence interval -1.14 to -0.66; number of trials = 39) and also for associated symptoms of depression, but not anxiety. Trauma-focused therapies were the most effective interventions across all populations for post-traumatic stress disorder and depression. Multicomponent and trauma-focused interventions were effective for negative self-concept. Phase-based approaches were also superior to the control for post-traumatic stress disorder and depression and showed the most benefit for managing emotional dysregulation and interpersonal problems. Only antipsychotic medication was effective for reducing post-traumatic stress disorder symptoms; medications were not effective for mental comorbidities. Eight qualitative studies were included. Interventions were more acceptable if service users could identify benefits and if they were delivered in ways that accommodated their personal and social needs.

LIMITATIONS

Assessments about long-term effectiveness of interventions were not possible. Studies that included outcomes related to comorbid psychiatric states, such as borderline personality disorder, and populations from prisons and humanitarian crises were under-represented.

CONCLUSIONS

Evidence-based psychological interventions are effective and acceptable post treatment for reducing post-traumatic stress disorder symptoms and depression and anxiety in people with complex trauma. These interventions were less effective in veterans and had less of an impact on symptoms associated with complex post-traumatic stress disorder.

FUTURE WORK

Definitive trials of phase-based versus non-phase-based interventions with long-term follow-up for post-traumatic stress disorder and associated mental comorbidities.

Therapeutic Change in Group Therapy For Interpersonal Trauma: A Relational Framework for Research and Clinical Practice

Our understanding of therapeutic change processes in group therapy for complex interpersonal trauma has been limited. The present study aimed at addressing this gap by developing a framework of therapeutic change in this field from a survivor and therapist perspective. This is a qualitative study, which utilized semistructured individual interviews. Transcripts were analyzed using interpretative phenomenological analysis (IPA) to identify recurrent themes. A final sample of n = 16 patients and n = 5 facilitators completed the interview. Main change processes identified by survivors were as follows: self versus others, trust versus threat, confrontation versus avoidance, and "patching up" versus true healing. Therapeutic processes identified by therapist facilitators included managing group dynamics, unpredictability and uncertainty, and process versus content. The proposed framework explains therapeutic change in group therapy in relational terms, that is, therapeutic dissonance, the dynamic interaction of self and experience as well as building empathic trusting relations. The importance of managing dissonance to aid personally meaningful recovery was highlighted. These findings have implications for the usefulness of relational and person-centered approaches to clinical practice in the area of interpersonal and complex trauma, especially in the early identification, prevention, and management of dropouts.

A Comparative Effectiveness Study of a Shortened Trauma Recovery Empowerment Model and an Attachment-Informed Adaptation

Relational challenges often associated with interpersonal trauma may hinder survivors' abilities to fully benefit from group therapy. This quasi-experimental study compared clinical outcomes of a 16-week version of the Trauma Recovery and Empowerment Model (TREM) for women and an attachment-informed adaptation (ATREM). Prior findings of TREM are extended by demonstrating that both group conditions can facilitate comparable clinical outcomes, creating options for group facilitators. Only ATREM resulted in statistically significant improvement in individual attachment avoidance, and it trended toward a slightly higher completion rate. This study provides insight into the emerging concept of group attachment.
