Acceptance and commitment therapy for co-occurring PTSD and substance use: A manual development study

Effects of comorbid posttraumatic stress disorder on cognitive dysfunction in Chinese male methamphetamine patients

OBJECTIVES

Cognitive dysfunction and posttraumatic stress disorder (PTSD) are common in methamphetamine patients. However, few studies have investigated the cognitive performance of methamphetamine patients with PTSD. The purpose of this study was to investigate the impact of comorbid PTSD on cognitive function in Chinese male methamphetamine patients.

METHODS

We analyzed 464 methamphetamine patients and 156 healthy volunteers. The PTSD Screening Scale (PCL-5) was used to assess PTSD and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was used to assess cognitive function.

RESULTS

Compared with healthy controls, methamphetamine patients had more cognitive dysfunction in immediate memory, visuospatial/constructional, language, attention and delayed memory. Moreover, methamphetamine patients with PTSD had less cognitive dysfunction in immediate memory, attention, and delayed memory than methamphetamine patients without PTSD. Further stepwise regression analysis showed that PTSD alterations in arousal and reactivity cluster were risk predictors for language, and PTSD negative alteration in cognition and mood cluster were risk predictors for delayed memory.

CONCLUSIONS

Our results indicate that methamphetamine patients without PTSD have poorer cognitive dysfunction than those with PTSD. Some demographic and PTSD symptom clusters are protective or risk factors for cognitive dysfunction in methamphetamine patients.

Trauma cue-elicited emotional response profiles influence acute experiences of alcohol urge

BACKGROUND AND OBJECTIVES

Affective responses to trauma cues in individuals with posttraumatic stress (PTS) can evoke a desire to drink and may shed light on novel mechanisms of PTS-drinking. The present study aimed to (1) identify and characterize patterns of acute emotional responses (ER) to trauma cues and (2) examine how these patterns influence drinking urge.

METHODS

University students (N = 304; M_age = 19; 52.3% female) completed a structured clinical interview to confirm trauma history and PTS. At an experimental session one week later, participants completed a series of three trauma cue exposures. Affect and drinking urge were measured at baseline, after each cue exposure, and at experiment's end.

RESULTS

Latent profile analysis of ER yielded a five-profile solution: (1) Nonresponders (2) Low Responders (3) Moderate Responders (4) Resilient Responders and (5) High Responders. Profiles differed by trait neuroticism, PTS, and emotion dysregulation, with High Responders as the most severe group. In latent growth curve models, profiles significantly predicted alcohol urge trajectories in a graded pattern. High Responders, with the greatest affective intensity, showed the strongest urge. Duration of affect was also implicated with Resilient Responders, who had similar intensity but faster overall affective recovery time compared to High Responders, demonstrating lower mean levels of urge.

LIMITATIONS

External validity is limited.

CONCLUSIONS

Individual differences in ER to trauma cues are important for understanding alcohol urge. Findings can inform integrative treatments for PTS-drinking by targeting ER to shorten affective recovery to trauma reminders and reduce the need for alcohol use as a regulation strategy.

Practical Considerations for Treating Comorbid Posttraumatic Stress Disorder in the Addictions Clinic: Approaches to Clinical Care, Leadership, and Alleviating Shame

A practical, common-sense framework for recognizing and addressing comorbid posttraumatic stress disorder (PTSD) in the substance use disorder (SUD) clinic is outlined. The article focuses on strategies that can help establish trauma-informed care or augment an existing approach. Interventions are organized around the task of ameliorating shame (or shame sensitivity), which represents a transdiagnostic mediator of psychopathology and, potentially, capacity for change. Countershaming strategies can guide a trauma-responsive leadership approach. Considering the striking rate of underdiagnosis of PTSD among patients with SUD, implementing routine systematic PTSD screening likely represents the single most consequential trauma-informed intervention that SUD clinics can adopt.

ACT-Informed Treatment of Co-morbid Psychiatric Disorders in the Postpartum Period: A Case Report

The literature describing psychological interventions for co-occurring obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) is limited. Acceptance and Commitment Therapy (ACT) is a transdiagnostic intervention that targets functionally avoidant behavior underlying both OCD and PTSD. The current case report describes how an ACT-informed approach to treatment was implemented over 14 sessions to treat co-occurring OCD and PTSD in a 9-months postpartum adult woman. The patient was initially referred to psychotherapy by her psychiatrist and showed high motivation to engage in treatment. This case presentation outlines how the intervention targeted core ACT processes while also incorporating components from both exposure and response prevention (ERP) and cognitive processing therapy (CPT) to address the patient’s presenting concerns. Measurements of OCD and PTSD symptom severity, as well as of depressive and anxiety symptoms, over the course of treatment are included. Health-related comorbidities, psychiatric medications, and implications are discussed.

The Choice Point Model of Acceptance and Commitment Therapy With Inpatient Substance Use and Co-occurring Populations: A Pilot Study

Objectives: Acceptance and Commitment Therapy (ACT) is an empirically supported treatment which aims to enhance self-acceptance and a commitment to core values. The present study examined the effectiveness of the Choice Point model of ACT in a residential substance use disorder (SUD) setting. Choice Point is a contemporary approach to ACT and targets transdiagnostic processes.

Methods: This uncontrolled quasi-experimental design assessed 47 participants taking part in Choice Point for Substances (CHOPS) in order to investigate its influence on psychological inflexibility, values-based action, and self-compassion over time. The study additionally assessed for sleeper effects and associations between transdiagnostic processes and warning signs of relapse.

Results: Findings demonstrated a decrease in psychological inflexibility and increases in values-based action and self-compassion over time. Gains were maintained at follow-up, and sleeper effects were observed for psychological inflexibility and mindfulness. Correlational analysis suggested that all transdiagnostic processes were related to warning signs of relapse at follow-up.

Conclusion: These results provide preliminary evidence for the feasibility, acceptability, and effectiveness of CHOPS for SUD. Observed sleeper effects in psychological inflexibility and mindfulness indicate that CHOPS may provide longer-term benefits critical to a population where relapse is common. While encouraging, these findings should be interpreted with caution. Future research should utilize comparison groups when investigating CHOPS.

Dynamics of risk: Recent changes in psychological inflexibility precede subsequent changes in returning US veterans' posttraumatic stress

OBJECTIVES

As a malleable risk-factor, psychological inflexibility is implicated in the development and maintenance of posttraumatic stress symptoms (PTS). Unfortunately, limited research has addressed whether changes in psychological inflexibility are antecedent to changes in PTS severity over time, or whether such changes are mutually dependent.

METHODS

Utilizing bivariate latent difference score modeling, this longitudinal study sequenced intraindividual changes in psychological inflexibility and PTS severity within a sample of 305 returning US veterans. Veterans' self-reported psychological inflexibility and PTS severity were assessed quarterly over 1 year.

RESULTS

Results indicated that early reductions in psychological inflexibility potentiated later declines in veterans' PTS severity, accounting for veterans' prior levels of psychological inflexibility and PTS severity.

CONCLUSIONS

These findings underscore the unique role of changes in psychological inflexibility as an important mechanism of change in PTS severity and provide empirical support for an antecedent model of the role of psychological inflexibility in PTS recovery.

Efficacy of third wave cognitive behavioral therapies in the treatment of posttraumatic stress: A meta-analytic study

The purpose of the present study was to examine, via meta-analysis, the efficacy of third wave therapies in reducing posttraumatic stress (PTS) symptoms. A secondary aim was to identify whether treatment efficacy was moderated by treatment type, treatment duration, use of exposure, use of intent-to-treat samples, and treatment format (i.e., individual, group, both). Risk of bias was also assessed. A literature search returned 37 studies with a pooled sample of 1268 participants that met study inclusion criteria. The mean differences between pre- and post-treatment PTS symptoms were estimated using a random effects model (i.e., uncontrolled effect). Additionally, in a subset of studies that utilized a control condition, a controlled effect in which pre- to post-treatment PTS symptom changes accounted for symptom changes in the control condition was calculated. The overall uncontrolled effect of third wave therapies in reducing PTS symptoms was medium to large (Hedges' g = 0.88 [0.72-1.03]). Treatment type, use of intent-to-treat analysis, inclusion of exposure, and format moderated the uncontrolled effect, but treatment duration did not. The controlled effect of third wave therapies was small to large in size (Hedges' g = 0.50 [0.20-0.80]). Findings suggest that third wave therapies demonstrate enough promise in treating individuals with PTS symptoms to warrant further investigation. Implications and suggestions for future third wave research are discussed.

Acceptance and Commitment Therapy for Co-Occurring Posttraumatic Stress Disorder and Alcohol Use Disorders in Veterans: Pilot Treatment Outcomes

Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) frequently co-occur and are associated with worse outcomes together than either disorder alone. A lack of consensus regarding recommendations for treating PTSD-AUD exists, and treatment dropout is a persistent problem. Acceptance and Commitment Therapy (ACT), a transdiagnostic, mindfulness- and acceptance-based form of behavior therapy, has potential as a treatment option for PTSD-AUD. In this uncontrolled pilot study, we examined ACT for PTSD-AUD in 43 veterans; 29 (67%) completed the outpatient individual therapy protocol (i.e., ≥ 10 of 12 sessions). Clinician-assessed and self-reported PTSD symptoms were reduced at posttreatment, ds = 0.79 and 0.96, respectively. Self-reported symptoms of PTSD remained lower at 3-month follow-up, d = 0.88. There were reductions on all alcohol-related outcomes (clinician-assessed and self-reported symptoms, total drinks, and heavy drinking days) at posttreatment and 3-month follow-up, d_mean = 0.91 (d range: 0.65-1.30). Quality of life increased at posttreatment and follow-up, ds = 0.55-0.56. Functional disability improved marginally at posttreatment, d = 0.35; this effect became significant by follow-up, d = 0.52. Fewer depressive symptoms were reported at posttreatment, d = 0.50, and follow-up, d = 0.44. Individuals experiencing suicidal ideation reported significant reductions by follow-up. Consistent with the ACT theoretical model, these improvements were associated with more between-session mindfulness practice and reductions in experiential avoidance and psychological inflexibility. Recommendations for adapting ACT to address PTSD-AUD include assigning frequent between-session mindfulness practice and initiating values clarification work and values-based behavior assignments early in treatment.

Barriers to self-compassion for female survivors of childhood maltreatment: The roles of fear of self-compassion and psychological inflexibility

Preliminary evidence has demonstrated the benefits of targeting self-compassion in the treatment of posttraumatic stress disorder (PTSD). However, survivors of childhood maltreatment may present with unique challenges that compromise the effectiveness of these and other PTSD treatments. Specifically, childhood maltreatment victims often exhibit a marked fear and active resistance of self-kindness and warmth (i.e., fear of self-compassion). Victims may also attempt to control distressing internal experiences in a way that hinders engagement in value-based actions (i.e., psychological inflexibility). Research suggests that psychological inflexibility exacerbates the negative effects of fear of self-compassion. The present study expanded on previous research by examining the relations among childhood maltreatment, fear of self-compassion, psychological inflexibility, and PTSD symptom severity in 288 college women. As expected, moderate to severe levels of childhood maltreatment were associated with greater fear of self-compassion, psychological inflexibility, and PTSD symptom severity compared to minimal or no childhood maltreatment. A mediation analysis showed that childhood maltreatment had a significant indirect effect on PTSD symptom severity via fear of self-compassion, although a conditional process analysis did not support psychological inflexibility as a moderator of this indirect effect. A post hoc multiple mediator analysis showed a significant indirect effect of childhood maltreatment on PTSD symptom severity via psychological inflexibility, but not fear of self-compassion. These findings highlight the importance of addressing fear of self-compassion and psychological inflexibility as barriers to treatment for female survivors of childhood maltreatment.
