Race and cultural factors in an RCT of prolonged exposure and sertraline for PTSD

State of the Science: Prolonged exposure therapy for the treatment of posttraumatic stress disorder

Prolonged exposure therapy (PE) is a well-established first-line treatment for posttraumatic stress disorder (PTSD) that is based on emotional processing theory. PE has been rigorously evaluated and tested in a large number of clinical trials in many countries covering a wide range of trauma populations. In this review, we summarize the evidence base supporting the efficacy of PE across populations, including adults with sexual assault-related PTSD and mixed trauma-related PTSD, military populations, and adolescents. We highlight important strengths and gaps in the research on PE with individuals from marginalized communities. We discuss the efficacy of PE on associated psychopathology and in the presence of the most commonly comorbid conditions, either alone or integrated with other treatments. In addition, we provide an overview of research examining strategies to augment PE. Much of this work remains preliminary, but numerous trials have tested PE in combination with other psychological or pharmacological approaches, interventions to facilitate extinction learning, and behavioral approaches, in the hopes of further increasing the efficiency and efficacy of PE. There are now several trials testing PE in novel formats that may have advantages over standard in-person PE, such as lower dropout and increased scalability. We examine this recent work on new models of delivering PE, including massed treatment, telehealth, and brief adaptations for primary care, all of which have the potential to increase access to PE. Finally, we highlight several promising areas for future research.

[Evidence-based psychotherapy of posttraumatic stress syndrome-An update]

BACKGROUND

The aim of this article is to summarize the current state of research on the effectiveness of psychotherapeutic treatment of posttraumatic stress disorder (PTSD).

METHODS

The results of current meta-analyses and trend-setting individual studies are summarized and the most important forms of intervention are explained.

RESULTS

The psychotherapeutic treatment methods for PTSD are very effective, the effect sizes are large and superior to those of pharmacotherapy. Trauma exposure and cognitive restructuring are most effective. Trauma-focused procedures are generally superior to other forms of psychotherapy. A range of different cognitive behavioral procedures as well as eye movement desensitization and reprocessing are recommended. The most recent initial findings confirm a very good effectiveness for imagery rescripting methods as protective interventions without a formal confrontation with trauma. Individual therapy works better than group psychotherapy. In the group setting cognitive processing therapy has proven to be the best intervention. Trauma-focused treatment should also be used when comorbid conditions such as schizophrenia, bipolar disorder or addiction are present.

DISCUSSION

Trauma-focused psychotherapy in an individual setting is the treatment of choice for PTSD. A large selection of effective methods and well-reviewed manuals are available. The German language S3 guidelines are currently being updated.

Treatment of posttraumatic stress disorder with prolonged exposure for primary care (PE-PC): Effectiveness and patient and therapist factors related to symptom change and retention

Prolonged exposure (PE) is a first-line treatment for posttraumatic stress disorder (PTSD) available in specialty mental health. PE for primary care (PE-PC) is a brief version of PE adapted for primary care mental health integration, composed of four-eight, 30-min sessions. Using retrospective data of PE-PC training cases from 155 Veterans Health Administration (VHA) providers in 99 VHA clinics who participated in a 4- to 6-month PE-PC training and consultation program, we examined patients' PTSD and depression severity across sessions via mixed effects multilevel linear modeling. Additionally, hierarchical logistic regression analysis was conducted to assess predictors of treatment dropout. Among 737 veterans, medium-to-large reductions in PTSD (intent-to-treat, Cohen's d = 0.63; completers, Cohen's d = 0.79) and small-to-medium reductions in depression (intent-to-treat, Cohen's d = 0.40; completers, Cohen's d = 0.51) were observed. The modal number of PE-PC sessions was five (SD = 1.98). Providers previously trained in both PE and cognitive processing therapy (CPT) were more likely than providers who were not trained in either PE or CPT to have veterans complete PE-PC (OR = 1.54). Veterans with military sexual trauma were less likely to complete PE-PC than veterans with combat trauma (OR = 0.42). Asian American and Pacific Islander veterans were more likely than White veterans to complete treatment (OR = 2.93). Older veterans were more likely than younger veterans to complete treatment (OR = 1.11). (PsycInfo Database Record (c) 2023 APA, all rights reserved).

MDMA-Assisted Therapy for Posttraumatic Stress Disorder: A Mixed-Methods Case Study of a Participant of Color From an Open-Label Trial

MDMA (±3,4-methylenedioxymethamphetamine)-assisted therapy (MDMA-AT) was shown in previous clinical trials to have promising efficacy and safety for alleviating treatment-resistant posttraumatic stress disorder (PTSD). However, due to low ethnoracial diversity, the question remains as to whether ethnoracial minority participants would benefit similarly. Thus, a mixed-methods case study was conducted on a participant of color from an open-label trial of MDMA-AT for PTSD to provide a culturally informed lens on symptom recovery with this treatment approach. An additional aim was to elucidate mechanisms of change underlying this treatment for the participant. A case profile was provided, documenting quantitative improvement in PTSD symptoms. This was followed by an interpretative phenomenological analysis (IPA) of effects and mechanisms of action for this participant, based on integration session transcripts. Results of IPA indicated recurrent themes related to psychological mechanisms of symptom change, reduced PTSD symptoms, and additional effects (positive and negative) beyond PTSD symptom reduction. These themes were discussed and recommendations for attuning to culturally relevant material during MDMA-AT were provided.

Culture, Ethnicity, and Level of Education in Alzheimer's Disease

Alzheimer's disease (AD) is the most frequent cause of dementia, where the abnormal accumulation of beta-amyloid (Aβ) and tau lead to neurodegeneration as well as loss of cognitive, behavioral, and functional abilities. The present review analyzes AD from a cross-cultural neuropsychological perspective, looking at differences in culture-associated variables, neuropsychological test performance and biomarkers across ethnic and racial groups. Studies have found significant effects of culture, preferred language, country of origin, race, and ethnicity on cognitive test performance, although the definition of those grouping terms varies across studies. Together, with the substantial underrepresentation of minority groups in research, the inconsistent classification might conduce to an inaccuratte diagnosis that often results from biases in testing procedures that favor the group to which test developers belong. These biases persist even after adjusting for variables related to disadvantageous societal conditions, such as low level of education, unfavorable socioeconomic status, health care access, or psychological stressors. All too frequently, educational level is confounded with culture. Minorities often have lower educational attainment and lower quality of education, causing differences in test results that are then attributed to culture. Higher levels of education are also associated with increased cognitive reserve, a protective factor against cognitive decline in the presence of neurodegeneration. Biomarker research suggests there might be significant differences in specific biomarker profiles for each ethnicity/race in need of accurate cultural definitions to adequately predict risk and disease progression across ethnic/racial groups. Overall, this review highlights the need for diversity in all domains of AD research that lack inclusion and the collection of relevant information from these groups.

Exposure therapy for PTSD: A meta-analysis

Posttraumatic stress disorder (PTSD) is associated with high morbidity and functional impairment in the absence of effective treatment. Exposure therapy for PTSD is a trauma-focused treatment that typically includes in vivo and/or imaginal exposure. The goal of this meta-analysis was to examine the overall efficacy of exposure therapy for PTSD compared to various control conditions. We also assessed the efficacy of individual exposure-based treatments and the potentially moderating impact of various demographic, clinical, and treatment-related factors. PsycINFO and Medline were searched for randomized controlled trials of exposure-based therapies for adult PTSD. A total of 934 abstracts were screened for initial eligibility; of these, 65 articles met inclusion criteria and were included in the meta-analysis (total N = 4929 patients). Exposure therapy showed large effects relative to waitlist and treatment-as-usual, a small effect relative to non-trauma-focused comparators and a negligible effect relative to other trauma-focused treatments or medication. At follow-up most effects sizes were stable, except for a medium effect favoring exposure over medication. The individual exposure-based therapies examined were similarly effective. Moderator analyses revealed larger effect sizes in studies with fewer sessions, younger samples, fewer participants diagnosed with substance use disorder, and fewer participants on psychiatric medication. Effect sizes were also larger in studies of refugees and civilians compared to military samples, studies of PTSD related to natural disasters and transportation accidents vs. other traumatic events, and studies of individual vs. group therapy. Findings support the overall efficacy of exposure therapy and highlight that there are a number of efficacious exposure-based therapies available.

One-year follow-up of treatment outcomes and patient opinions of Retraining and Control Therapy (ReACT) for pediatric functional seizures

Retraining and Control Therapy (ReACT), a short-term treatment for pediatric functional seizures (FS), has been demonstrated to improve FS in children compared to supportive therapy. However, long-term maintenance of FS-reduction after ReACT is unclear. This study aims to assess seizure frequency 1 year after ReACT and determine patient and parents' opinions of ReACT. Children with functional seizures who previously completed ReACT and their parents were asked to report 30-day FS frequency 1 year after completing ReACT. They also reported if ReACT was helpful. Paired samples t-tests were used to compare FS frequency before ReACT to 1 year after and to compare FS frequency in 30 days after ReACT to 1 year after. Fourteen children (Mean_age = 15.43) and their parents participated. Seven-day FS frequency for patients at 1-year follow-up (Mean = 0.15) was significantly lower than 7-day FS frequency pre-ReACT (Mean = 5.62; p = 0.005). No differences were found when comparing FS frequency during 30 days post-ReACT (Mean = 0.29) and in 30 days before 1-year follow-up (Mean = 0.71). This study confirms long-term maintenance of FS-reduction after ReACT and supports the efficacy of targeting FS directly as opposed to mood or stress for reducing FS. Additionally, children and parents believe ReACT is beneficial.
