Perspectives on a Stage-Based Treatment for Posttraumatic Stress Disorder Among Dialectical Behavior Therapy Consumers in Public Mental Health Settings

How is trauma-focused therapy experienced by adults with PTSD? A systematic review of qualitative studies

BACKGROUND

Trauma-focused therapies (TFTs) are first-line treatments for posttraumatic stress disorder (PTSD). However, TFTs are under-utilised, partly due to clinicians' and patients' fear that TFT is too challenging or harmful. We review the qualitative studies on how adults with PTSD experience TFTs to enhance the understanding of user perspectives, therapeutic processes, and outcomes.

METHODS

PubMed, PsychINFO and PTSDPubs were searched between October 1st and November 30th, 2021. Study quality assessments were undertaken, and studies were analysed using a descriptive-interpretative approach. Nine studies were included.

RESULTS

The analysis resulted in the identification of four key domains, representing a temporal sequence of TFT stages: Overcoming ambivalence towards TFT, Experience of treatment elements, Motivation for dropout/retention, and Perceived changes post-treatment.

CONCLUSION

Although many participants reported high levels of distress and considered dropping out, only a minority did eventually drop out and most patients expressed that the hardships in therapy were necessary for PTSD improvement. Establishing a safe therapeutic environment and working with the ambivalence towards treatment was essential for retention. This review serves a dual purpose, to shed light on diverse TFT experiences found to be important for treatment satisfaction, and to elucidate common treatment patterns. The results can be used in preparing patients for therapy and in training TFT therapists. Studies had moderate to high quality, and more studies of experiences of TFT non-responders and dropouts in a non-veteran population are needed to further our understanding of the utility and limitations of TFTs.

Trauma-Informed Care in Psychedelic Therapy Research: A Qualitative Literature Review of Evidence-Based Psychotherapy Interventions in PTSD and Psychedelic Therapy Across Conditions

Introduction

Post-traumatic stress disorder (PTSD) is associated with significant patient burden. While pharmacotherapies and evidence-based psychotherapy interventions (EBPI) are effective, studies consistently highlight inadequate outcomes and high treatment dropout. Psychedelic therapy (PT) has shown preliminary promise across difficult-to-treat conditions, including MDMA-assisted therapy for PTSD, however trials of classical psychedelics in PTSD are lacking. Understanding patients' experiences of EBPI could help promote safety in PT.

Aim

To systematically review qualitative research on patients' subjective experience of EBPI for PTSD, and of PT, and examine areas of overlap and divergence between them.

Methods

Systematic literature searches for studies published between 2010 and 2023 were conducted on OVID, PubMed, Web of Science, and PsycInfo. Included were original studies in English that presented qualitative data of patient experiences of EBPI in PTSD, or PT for any indication. Extracted data from included studies were analysed using thematic synthesis. Syntheses were completed separately for EBPI and PT, before similarities and differences between the therapies were identified.

Results

40 research articles were included for review: 26 studies on EBPI for PTSD, and 14 studies on PT. EBPI studied were CBT, EMDR, CPT and PE. Psychedelic compounds studied were psilocybin, ibogaine, LSD, MDMA and ketamine, for treatment of substance use disorders, anxiety relating to physical illness, depression, and PTSD. Core themes from patient experiences of EBPI: 1) patient burden in PTSD treatment; 2) readiness; 3) key mechanisms of change; 4) psychological safety and trust. Themes identified in the review of PT: 1) indirect trauma processing; 2) reorganisation of self-narratives via processes of relatedness and identification; 3) key treatment characteristics.

Conclusion

This study suggests overlap between patients' experience of EBPI and PT in terms of key mechanisms of change, the importance of psychological safety and readiness to engage in treatment. Trauma-informed care paradigms and practices may improve safety and acceptability of PT research.

Does Adding the Dialectical Behavior Therapy Prolonged Exposure (DBT PE) Protocol for PTSD to DBT Improve Outcomes in Public Mental Health Settings? A Pilot Nonrandomized Effectiveness Trial With Benchmarking

The Dialectical Behavior Therapy Prolonged Exposure (DBT PE) protocol improves DBT's effects on PTSD in research settings, but its effectiveness in community settings is largely unknown. This pilot nonrandomized controlled trial examined DBT with and without DBT PE in four public mental health agencies. Patients (N = 35, 12-56 years old, 80.0% female, 64.7% racial/ethnic minorities, 44.1% sexual minorities) had PTSD, were receiving DBT, and completed assessments every four months over one year. Sixteen patients (45.7%) initiated DBT PE, 19 (54.3%) did not, and dropout did not differ between groups (31.3% vs. 26.3%). The primary barrier to initiating DBT PE was clinician turnover (57.9% of non-initiators). After adjusting for confounds, DBT PE initiators (g = 1.1) and completers (g = 1.4) showed a greater reduction in PTSD than patients who received DBT only (g = 0.5; p's < .05). Rates of reliable improvement in PTSD were 71.4% (DBT PE completers), 53.8% (DBT PE initiators), and 31.3% (DBT). Similar patterns were observed for posttraumatic cognitions, emotion dysregulation, general psychological distress, and limited activity days. There was no worsening of self-injurious behavior or crisis service use among patients who received DBT PE. Benchmarking analyses indicated comparable feasibility, acceptability, and safety, but a smaller magnitude of clinical change, than in efficacy studies. Results require replication in a randomized trial but suggest that DBT PE can be transported effectively to community settings.

Patient and Therapist Perspectives on Treatment for Adults with PTSD from Childhood Trauma

This study aimed to explore patients’ and therapists’ experiences with trauma-focused treatments in patients with posttraumatic stress disorder from childhood trauma (Ch-PTSD). Semi-structured interviews were conducted with patients (n = 44) and therapists (n = 16) from an international multicentre randomised clinical trial comparing two trauma-focused treatments (IREM), imagery rescripting and eye movement and desensitisation (EMDR). Thematic analysis was used to identify key themes within the data. Patients and therapists commented about the process of therapy. The themes that emerged from these comments included the importance of the patients’ willingness to engage and commit to the treatment process; the importance and difficulty of the trauma work, observations of how the trauma focused therapy produced changes in insight, and sense of self and empowerment for the future. In addition, therapists made suggestions for optimising the therapist role in the trauma-focused treatment. This included the importance of having confidence in their own ability, confronting their own and their client’s avoidance and the necessity and difficulties of adhering to the treatment protocols. These reported experiences add further support to the idea that trauma-focused treatments, without a stabilisation phase, can be tolerated and deepens our understanding of how to make this palatable for individuals with Ch-PTSD.
