The potential of 5-methoxy-N,N-dimethyltryptamine in the treatment of alcohol use disorder: A first look at therapeutic mechanisms of action

Alcohol use disorder (AUD) remains one of the most prevalent psychiatric disorders worldwide with high economic costs. Current treatment options show modest efficacy and relapse rates are high. Furthermore, there are increases in the treatment gap and few new medications have been approved in the past 20 years. Recently, psychedelic-assisted therapy with psilocybin and lysergic acid diethylamide has garnered significant attention in the treatment of AUD. Yet, they require significant amounts of therapist input due to prolonged subjective effects (~4-12 h) leading to high costs and impeding implementation. Accordingly, there is an increasing interest in the rapid and short-acting psychedelic 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT). This paper offers a first look at potential therapeutic mechanisms for AUD by reviewing the current literature on 5-MeO-DMT. Primarily, 5-MeO-DMT is able to induce mystical experiences and ego-dissolution together with increases in psychological flexibility and mindfulness. This could decrease AUD symptoms through the alleviation of psychiatric mood-related comorbidities consistent with the negative reinforcement and self-medication paradigms. In addition, preliminary evidence indicates that 5-MeO-DMT modulates neural oscillations that might subserve ego-dissolution (increases in gamma), psychological flexibility and mindfulness (increases in theta), and the reorganization of executive control networks (increases in coherence across frequencies) that could improve emotion regulation and inhibition. Finally, animal studies show that 5-MeO-DMT is characterized by neuroplasticity, anti-inflammation, 5-HT2A receptor agonism, and downregulation of metabotropic glutamate receptor 5 with clinical implications for AUD and psychiatric mood-related comorbidities. The paper concludes with several recommendations for future research to establish the purported therapeutic mechanisms of action.

Unconscious and conscious acceptance downregulate aggressive behavior: Mediating role of anger regulation

Social exclusion can induce negative emotions and aggression. While previous studies have investigated the effect of trait acceptance on emotional experience and aggression during social exclusion, it is still unclear how different forms of acceptance strategy can downregulate negative emotions and whether this potential reduction of negative emotions should mediate the effect of acceptance on aggression. To address these questions, 100 participants were recruited and randomly divided into three groups: control group (CG, N = 33), conscious acceptance group (CAG, N = 33) and unconscious acceptance group (UAG, N = 34). Negative emotions were induced by the cyberball game and measured by the modified PANAS. Aggressive behavior was assessed by the hot sauce allocation task. Results showed that anger, rather than other negative emotions, mediated the effect of acceptance on aggressive behavior. Conscious and unconscious acceptance both effectively regulated anger, hurt feelings and aggressive behavior during social exclusion. Compared to conscious acceptance, unconscious acceptance was associated with less reduction of positive emotion and had a better effect on reducing sadness. These findings highlight the advantage of applying unconscious acceptance strategy to regulating social exclusion-induced emotions for the purpose of reducing aggressive behavior.

Outcomes of Acceptance and Commitment Therapy for depression and predictors of treatment response in Veterans Health Administration patients

BACKGROUND

Acceptance and Commitment Therapy for depression (ACT-D) is a promising depression treatment which has not been evaluated on a large scale within VA. This study aimed to evaluate ACT-D's effectiveness in a national, treatment-seeking sample of Veterans.

METHODS

The sample comprised 831 Veterans who received a primary depression diagnosis and received at least two sessions of ACT-D during fiscal years 2015-2020. We used GLM to measure predictors of symptom change, treatment response (50 % reduction in PHQ-9 and AAQ-II scores), subthreshold depression symptoms (PHQ-9 < 10; AAQ-II < 27), and treatment completion.

RESULTS

Veterans experienced an average reduction of 3.39 points on the PHQ-9 (Cohen's d = 0.56) and 3.76 points on the AAQ-II (Cohen's d = 0.43). On the PHQ-9, 40 % achieved subthreshold depression symptoms. On the AAQ-II, 36 % of Veterans achieved subthreshold psychological inflexibility scores. Service-connected disability rating for depression and higher levels of medical comorbidity were both related to lower levels of overall depression symptom change and treatment response. Substance use disorder and bipolar/psychosis diagnoses were associated with greater reductions in psychological inflexibility.

LIMITATIONS

This is an observational study without a control group, so we were unable to compare the effectiveness of ACT-D to other usual care for depression. We were also unable to assess variables that can influence treatment success, such as therapist fidelity and patient engagement.

CONCLUSIONS

ACT-D achieved similar improvements in depression as reported in controlled trials. Adaptations to ACT-D may be needed to improve outcomes for Veterans with depression and comorbid PTSD.

Integrated Trauma-Focused Psychotherapy for Traumatic Stress and Substance Use: Two Adolescent Case Studies

Post-traumatic stress disorder (PTSD) and substance use disorder (SUD) occur frequently as comorbid diagnoses among adolescents. Historically, these conditions have been treated using a sequential model; however, emerging evidence suggests that an integrated treatment model may be most effective. This article presents two de-identified clinical case studies from an ongoing randomised controlled trial examining the efficacy of an integrated, exposure-based, cognitive-behavioral psychotherapy (CBT) for PTSD and SUD among adolescents (COPE-A), relative to a supportive counselling control condition (person-centred therapy). In both case studies, participants were randomised to receive the COPE-A integrated treatment, which incorporates prolonged exposure (PE) including imaginal and in vivo exposure as a core treatment component alongside CBT for PTSD and SUD. The clinical profile and treatment response of each participant is discussed. Promising results were found in both cases, with substantially reduced traumatic stress symptoms and decreased or stable levels of substance use by the end of treatment. Clinical implications of these early findings are discussed.

Toward trauma-informed applications of behavior analysis

Despite a growing acknowledgement of the importance of understanding the impacts of trauma on therapeutic approaches across human service disciplines, discussions of trauma have been relatively infrequent in the behavior analytic literature. In this paper, we delineate some of the barriers to discussing and investigating trauma in applied behavior analysis (ABA) and describe how the core commitments of trauma-informed care could be applied to behavior analysis. We then provide some examples of how trauma-informed care might be incorporated into ABA practice. We conclude by suggesting opportunities to approach trauma as a viable avenue for behavior analytic research and argue that omitting trauma-informed care from ABA could be detrimental not only to the public perception of ABA, but to the effectiveness of our assessment and treatment procedures.

Examining the Role of Craving, Mindfulness, and Psychological Flexibility in a Sample of Individuals with Substance Use Disorder

Substance Use Disorder (SUD) continues to represent a significant public health crisis in the United States. Purpose: Novel and effective treatments are needed, and third wave behavioral approaches focused on increasing mindfulness and psychological flexibility appear promising. However, the unique and shared impact of mindfulness and psychological flexibility on substance craving is not well understood. Methods: The current study explores how mindfulness and psychological flexibility predict substance craving while controlling for severity of substance dependence in a sample (N = 284) of treatment-seeking adults with SUD. Results and Discussion: Results suggest that mindfulness and psychological flexibility each account for unique variance in substance craving over and above the other. Implications and limitations are discussed.

Acceptance and Commitment Therapy Delivered via Telehealth for the Treatment of Co-Occurring Depression, PTSD, and Nicotine Use in a Male Veteran

Symptoms of depression, posttraumatic stress, and substance use disorders commonly co-occur and are a tremendous health burden among the U.S. military veteran population. Acceptance and Commitment Therapy (ACT) is an evidence-based, transdiagnostic, integrated approach that has been used to treat these problems. Delivering psychotherapy via telehealth helps to break down barriers to care. This case study describes the application of ACT via telehealth with a male veteran with co-occurring symptoms of depression, PTSD and nicotine addiction. His depressive symptoms, PTSD symptoms, and nicotine use decreased substantially over the course of therapy. He demonstrated increased willingness to experience negatively evaluated internal experiences such as emotions and urges to use nicotine, defusion from self-critical and other unhelpful thoughts, more consistent engagement in values-consistent behaviors, and increased behavioral engagement in his social life. Treatment implications and unique aspects of the telehealth modality are discussed. Recommendations are made for training clinicians who may be considering providing services via telehealth or using ACT.

Using acceptance and commitment therapy techniques to enhance treatment engagement in veterans with posttraumatic stress disorder

Evidence-based treatments for posttraumatic stress disorder (PTSD) are available for veterans, but many do not benefit due to low treatment engagement. This may be partially due to avoidance behaviors characteristic of individuals with PTSD. Acceptance and Commitment Therapy (ACT) is a transdiagnostic treatment approach that aims to reduce avoidance. The authors propose the use of adjunctive ACT techniques to enhance engagement with treatment for PTSD. ACT techniques such as cognitive defusion and values clarification have been shown to promote engagement with other cognitive-behavioral treatments, but no studies to date have examined these techniques as adjuncts to treatment for PTSD. Because of its focus on reducing avoidance, ACT is uniquely suited for promoting treatment engagement with the "gold standard" treatments for PTSD. The authors review the existing research on ACT as an adjunctive intervention, discuss specific concepts and techniques from ACT that are relevant to PTSD, and provide recommendations for future research.

Improving Social Support for a Veteran With PTSD Using a Manualized Acceptance and Commitment Therapy Approach

Posttraumatic stress disorder (PTSD) often negatively impacts social functioning, which can lead to increased risk of morbidity and mortality. Although current evidence-based and exposure-specific treatments can improve PTSD symptoms, they rarely target the interpersonal difficulties that impact quality of life. This case study describes the use of a manualized treatment for a veteran who continues to experience poor social functioning even after previous exposure-based treatment for PTSD. This treatment, ACT to Improve Social Support for Veterans with PTSD (ACT-SS), explicitly targeted the veteran’s maladaptive patterns of interpersonal difficulties, feelings of detachment from others, irritability, and avoidance of social situations. Following treatment, the veteran reported significant improvements in social relationships, quality of life, and depressive symptoms, even though he still met the clinical threshold for PTSD. This case study provides preliminary evidence for the efficacy of a psychosocial intervention that directly targets social functioning issues for veterans with PTSD, and the importance of incorporating social goals and exercises into treatment.

Childhood trauma and problem behavior: Examining the mediating roles of experiential avoidance and mindfulness processes

OBJECTIVE

Childhood trauma is associated with a variety of risky, unhealthy, or problem behaviors. The current study aimed to explore experiential avoidance and mindfulness processes as mechanisms through which childhood trauma and problem behavior are linked in a college sample.

PARTICIPANTS

The sample consisted of college-aged young adults recruited November-December, 2016 (N = 414).

METHODS

Participants completed self-report measures of childhood trauma, current problem behavior, experiential avoidance, and mindfulness processes. Bootstrapped mediation analyses examined the mechanistic associations of interest.

RESULTS

Mediation analyses indicated that experiential avoidance was a significant mediator of the association between childhood trauma and problem behavior. Additionally, multiple mediation analyses indicated that specific mindfulness facets-act with awareness and nonjudgment of inner experience-significantly mediated the same association.

CONCLUSIONS

Interventions for college students who have experienced childhood trauma might profitably target mechanisms such as avoidance and mindfulness in order to minimize engagement in problem behavior.

Psychological Inflexibility Predicts of Suicidal Ideation Over Time in Veterans of the Conflicts in Iraq and Afghanistan

Psychological inflexibility, or how individuals respond to distressing internal experiences, may be a modifiable risk factor for suicide in veterans. It was hypothesized that psychological inflexibility would predict suicidal ideation after accounting for established risk factors at baseline and 1 year later. Post-9/11 veterans (N = 309) completed clinical interview and self-report measures at baseline and 1-year follow-up. Results indicated that psychological inflexibility predicted severity of suicidal ideation at both baseline and 1 year later, after accounting for established risk factors. Psychological inflexibility is an important marker of risk for suicidal ideation, and could be a target for interventions aimed at reducing suicide.

Acceptance and Commitment Therapy and Motivational Interviewing in the Treatment of Alcohol Use Disorder in a College Woman: A Case Study

Alcohol abuse is common among college students. Acceptance and commitment therapy (ACT) is widely supported as a treatment of alcohol abuse. However, little research has examined how ACT may be paired with other techniques traditionally applied to treat substance abuse, such as motivational interviewing (MI). This clinical case study describes the use of ACT and MI to facilitate treatment of a 20-year-old woman who was referred for treatment for alcohol abuse. The client remained in treatment in spite of her initial self-reported belief that treatment was unnecessary. At follow-up, the client reported increased present moment awareness, particularly of her drinking habits, and demonstrated the ability to behave in ways consistent with her values. At the completion of treatment, the client reported fewer episodes of alcohol consumption and less severe drinking. Implications of these findings are discussed, with an emphasis on the potential benefits of pairing MI techniques with ACT.

Childhood emotional maltreatment, anxiety, attachment, and mindfulness: Associations with facial emotion recognition

The current study investigated factors thought to contribute to facial emotion processing. Female university students (N = 126) completed self-report measures of childhood emotional maltreatment, anxiety symptoms, attachment anxiety and avoidance, and trait mindfulness before completing a facial emotion recognition task, where they viewed sequences of faces that incorporated progressively more emotional content until they were able to correctly identify the emotion. They completed the task under low and high cognitive load conditions to distinguish between relatively effortful versus automatic processing abilities. Regression analyses revealed that under low cognitive load, attachment avoidance and mindfulness predicted quicker identification of fear (i.e., with less perceptual information), whereas anxiety predicted slower identification of fear (i.e., with more perceptual information). In the high cognitive load condition, emotional maltreatment and mindfulness predicted quicker identification of fear, and anxiety and mindfulness predicted faster identification of emotions overall. Although current findings are correlational, most of these effects were specific to fearful faces, suggesting that experiences of childhood emotional maltreatment and associated socio-emotional sequelae are related to heightened processing of threat-related information.

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.

Evidence-based Treatments for Military-related Posttraumatic Stress Disorder in a Veterans Affairs Setting

Posttraumatic stress disorder (PTSD) can have a significant negative impact on the physical, emotional, and mental health of individuals. This article discusses the prevalence, risk factors, and diagnostic criteria for PTSD. Given the high incidence of PTSD in the Veteran population, much attention has been given to assessment and treatment issues. Treatment options for PTSD, including the 2 most effective treatments, prolonged exposure and cognitive processing therapy, are discussed. Special issues concerning the treatment of Veterans are also reviewed.

Are Smoking Cessation Treatments Associated with Suicidality Risk? An Overview

Risk of suicidality during smoking cessation treatment is an important, but often overlooked, aspect of nicotine addiction research and treatment. We explore the relationship between smoking cessation interventions and suicidality and explore common treatments, their associated risks, and effectiveness in promoting smoking reduction and abstinence. Although active smokers have been reported to have twofold to threefold increased risk of suicidality when compared to nonsmokers,1–4 research regarding the safest way to stop smoking does not always provide clear guidelines for practitioners wishing to advise their patients regarding smoking cessation strategies. In this article, we review pharmacological and cognitive behavioral therapy (CBT) options that are available for people seeking to quit smoking, focusing on the relationship between the ability of these therapies to reduce smoking behavior and promote abstinence and suicidality risks as assessed by reported suicidality on validated measures, reports of suicidal ideation, behaviors, actual attempts, or completed suicides. Pharmacotherapies such as varenicline, bupropion, and nicotine replacement, and CBTs, including contextual CBT interventions, have been found to help reduce smoking rates and promote and maintain abstinence. Suicidality risks, while present when trying to quit smoking, do not appear to demonstrate a consistent or significant rise associated with use of any particular smoking cessation pharmacotherapy or CBT/contextual CBT intervention reviewed.

An initial meta-analysis of Acceptance and Commitment Therapy for treating substance use disorders

BACKGROUND

In the past decade, multiple studies have examined the effectiveness of Acceptance and Commitment Therapy (ACT) for substance use disorders relative to other active treatments. The current meta-analysis examined the aggregate effect size when comparing ACT to other treatments (e.g., CBT, pharmacotherapy, 12-step, treatment as usual) specifically on substance use outcomes.

METHOD

A total of 10 randomized controlled trials were identified through systematic searches.

RESULTS

A significant small to medium effect size was found favoring ACT relative to active treatment comparisons following treatment. Effect sizes were comparable across studies for smoking cessation (k=5) and for other drug use disorders (k=5).

CONCLUSIONS

Based on these findings, ACT appears to be a promising intervention for substance use disorders. Limitations and future directions are discussed.

Psychometric properties of the Portuguese version of the Acceptance and Action Questionnaire-Trauma Specific (AAQ-TS): A study with Portuguese Colonial War Veterans

BACKGROUND

The Acceptance and Action Questionnaire-Trauma Specific (AAQ-TS) is a self-report measure designed to assess-trauma-related psychological (in)flexibility, as conceptualized in Acceptance and Commitment Therapy. However, there are no studies to date regarding its psychometric properties. This study explores such properties in the Portuguese version of the AAQ-TS, in Portuguese Colonial War Veterans.

METHOD

A Principal Components Analysis (PCA) was conducted in a sample from the general population of war Veterans (N=371). Confirmatory Factor Analysis (CFA) as well as reliability and convergent validity studies were performed in a different sample from the same population (N=312). For the discriminant validity a clinical sample with a war-related PTSD (N=42) and a non-clinical sample without PTSD (N=44) were used.

RESULTS

The CFA suggested a re-specified 15-item model with good global adjustment and factorial validity. The AAQ-TS showed internal consistency, a good temporal reliability, convergent validity with psychopathological symptoms (related to PTSD, anxiety, depression and stress) and peritraumatic dissociation (altered awareness and depersonalization/derealization). The questionnaire also discriminates between war Veterans with and without a PTSD diagnosis.

LIMITATIONS

The major limitation relates to the samples' characteristics and sampling methods, which can limit the generalization of results.

CONCLUSION

The Portuguese version of the AAQ-TS is a reliable and valid measure to assess experiential avoidance related to trauma in Portuguese Colonial War Veterans.

Chronic pain acceptance incrementally predicts disability in polytrauma-exposed veterans at baseline and 1-year follow-up

War veterans are at increased risk for chronic pain and co-occurring neurobehavioral problems, including posttraumatic stress disorder (PTSD), depression, alcohol-related problems, and mild traumatic brain injury (mTBI). Each condition is associated with disability, particularly when co-occurring. Pain acceptance is a strong predictor of lower levels of disability in chronic pain. This study examined whether acceptance of pain predicted current and future disability beyond the effects of these co-occurring conditions in war veterans. Eighty trauma-exposed veterans with chronic pain completed a PTSD diagnostic interview, clinician-administered mTBI screening, and self-report measures of disability, pain acceptance, depression, and alcohol use. Hierarchical regression models showed pain acceptance to be incrementally associated with disability after accounting for symptoms of PTSD, depression, alcohol-related problems, and mTBI (total adjusted R(2) = .57, p < .001, ΔR(2) = .03, p = .02). At 1-year follow-up, the total variance in disability accounted for by the model decreased (total adjusted R(2) = .29, p < .001), whereas the unique contribution of pain acceptance increased (ΔR(2) = .07, p = .008). Pain acceptance remained significantly associated with 1-year disability when pain severity was included in the model. Future research should evaluate treatments that address chronic pain acceptance and co-occurring conditions to promote functional recovery in the context of polytrauma in war veterans.

A Functional and Cohesive Treatment of Tourette’s Disorder and Chewing Tobacco Use

Acceptance and commitment therapy (ACT) is a function-based treatment that can be applied to multiple clinical concerns where psychological inflexibility is a mediating issue. This case study describes the use of ACT in combination with habit reversal training for a man with a primary concern of Tourette’s disorder and a secondary concern of chewing tobacco use. Large reductions were seen in the primary outcomes of motor and vocal tics (measured by behavioral tracking and a semi-structured assessment) and chewing tobacco use after 19 individual sessions. Furthermore, increases in psychological flexibility and quality of life and decreases in overall symptomatology were seen at posttreatment. This article conceptualizes this case from a cohesive theory, describes the details of the presenting concerns, and explains the treatment used and treatment outcomes. A description of barriers and suggestions for further treatment and research are also presented.

The Promise of Third-Wave Behavioral Therapies in the Treatment of Substance Use Disorders

Substance use disorders are common and frequently complex, with overlapping medical, legal, social and psychiatric problems. Innovative treatment models to address the full range of problems in new ways using common principles are needed. Third wave behavior therapies such as Acceptance and Commitment Therapy (ACT) and Dialectical Behavior Therapy (DBT) comprise novel approaches and methods that have great potential to address complex substance abuse cases. These treatment models derive from contextual and behavioral science and have a common emphasis on developing empirical, principle-driven methods for approaching unwanted or distressing psychological and physical experiences common to substance use and other disorders. Randomized controlled trials targeting substance use with ACT and DBT have been conducted across varying populations, including various target substances (opiates, methamphetamine, polysubstance) and settings (prisons, methadone clinics, residential treatment, and outpatient). Despite methodological heterogeneity, ACT and DBT have compared favorably to passive and active control conditions. Further research is needed, however, with larger samples and active control conditions, along with studies of treatment mechanisms, to inform and shape theoretical models and substance abuse treatment protocols for enhanced efficacy.

Acceptance and commitment therapy for anxiety and OCD spectrum disorders: an empirical review

A fair amount of research exists on acceptance and commitment therapy (ACT) as a model and a treatment for anxiety disorders and OCD spectrum disorders; this paper offers a quantitative account of this research. A meta-analysis is presented examining the relationship between psychological flexibility, measured by versions of the Acceptance and Action Questionnaire (AAQ and AAQ-II) and measures of anxiety. Meta-analytic results showed positive and significant relationships between the AAQ and general measures of anxiety as well as disorder specific measures. Additionally, all outcome data to date on ACT for anxiety and OCD spectrum disorders are reviewed, as are data on mediation and moderation within ACT. Preliminary meta-analytic results show that ACT is equally effective as manualized treatments such as cognitive behavioral therapy. Future directions and limitations of the research are discussed.

Alleviation of Moral Disgust, Shame, and Guilt in Posttraumatic Stress Reactions

Research suggests that moral disgust, shame, and guilt are present in posttraumatic psychopathology. However, it is unclear that these emotional states are responsive to empirically supported interventions for posttraumatic stress symptoms (PTSS). This study explored the relations among moral disgust, shame, guilt, and PTSS, and examined comprehensive distancing (CD) as a novel intervention for these emotional states in undergraduates with elevated PTSS. Participants were randomly assigned to use a CD or a cognitive challenge task in response to personalized scripts of a traumatic event. Both interventions were associated with decreases in disgust, moral disgust, shame, and guilt. Contrary to predictions, there were no significant differences between the exercises in the reduction of negative emotions. In addition, PTSS severity was correlated with trauma-related guilt as well as state guilt and shame, but not trait or state measures of disgust or moral disgust. This proof of concept project sets the stage for further research examining CD as an alternative or adjunctive intervention for posttraumatic stress reactions with strong features of moral disgust, shame, and guilt.

Acceptance and Commitment Therapy for the Treatment of Posttraumatic Stress Among Adolescents

The number of individuals who meet diagnostic criteria for posttraumatic stress disorder (PTSD) is a small percentage of those exposed to trauma; many youth who do not meet criteria for PTSD continue to experience problematic posttraumatic stress (PTS) symptomology. Acceptance and commitment therapy (ACT) has shown preliminary effectiveness in the treatment of adult PTSD, but its effectiveness in treating PTS in youth is unknown. Using a multiple-baseline design, this study investigated the effectiveness of 10 weeks of ACT to treat PTS in youth. Four adolescents from a community sample and three adolescents from a residential sample participated. The Clinician Administered PTSD Scale for Children and Adolescents (CAPS-CA), Child PTSD Symptom Scale (CPSS), and Comprehensive Quality of Life Scale were completed at pretreatment, posttreatment, and 3-month follow-up. Individuals reported baseline data for 7 to 66 days. Symptom and process measures were completed at each session. Results revealed a decrease in PTS symptomology across both samples with mean reductions in self-reported PTS symptomology at posttreatment of 69% and 81% for the community and residential samples, respectively, and an overall 68% and 84% respective reduction at follow-up. Reductions in clinician rated measures of PTSD were observed for all participants with mean reductions of 57% and 61% in the community and residential samples at posttreatment, and 71% and 60% at follow-up, respectively. Results provide preliminary support for ACT as a treatment for adolescent PTS. Empirical and clinical implications as well as limitations and future directions are discussed.

Acceptance and Commitment Therapy With Survivors of Adult Sexual Assault

A number of studies have found experiential avoidance to mediate the relationship between sexual assault and adverse long-term effects. One treatment approach that has been developed for the treatment of experiential avoidance is Acceptance and Commitment Therapy (ACT). A small body of research has demonstrated preliminary efficacy for the use of ACT with trauma survivors suffering from posttraumatic stress disorder (PTSD). However, no treatment studies to date have evaluated ACT as a treatment model with survivors of adult sexual assault. In this case study, ACT was applied to an 18-year-old survivor of adult sexual assault suffering from PTSD symptoms. The results indicated that ACT was effective in reducing experiential avoidance, thought suppression, trauma symptomatology, and increasing valued action and quality of life. The findings of this study suggest that the use of grounding techniques, visual metaphors, and experiential mindfulness exercises in ACT may be particularly helpful for survivors of adult sexual assault.

A Systematic Review of Acceptance and Commitment Therapy (ACT) for Managing Anxiety: Applicability for People With Acquired Brain Injury?

Acceptance and commitment therapy (ACT) is increasingly used in clinical practice to manage anxiety conditions. This psychotherapeutic approach focuses on the following: (1) acceptance of an individual's experience of the spectrum of psychological and emotional states, (2) choosing valued direction for the individual's life, and (3) commitment to action that leads the individual in the direction of those values. This article presents an empirical review of ACT for treatment of anxiety in two parts. In the first part we systematically review the literature for studies examining ACT for anxiety management in the general population with anxiety problems. In the second part, we discuss applicability of acceptance-based approaches for a health population in which these techniques may have applicability, that is, for people with acquired brain injury (ABI). Electronic searches for the review were conducted on PsycINFO and Medline. Inclusion criteria were as follows: (1) used an ACT intervention study, (2) the target of the intervention was an anxiety disorder or anxiety symptomatology, (3) the intervention used a randomised controlled trial (RCT) or single case experimental design (SCED) methodology, and (4) the paper was available in English. Studies were rated for methodological quality using standardised assessment procedures. Four RCTs provided support for ACT for obsessive compulsive disorder (OCD), maths anxiety, trichotillomania (TTM), and mixed anxiety and depression. Three SCED trials scoring in the high range on the scale of methodological quality revealed some support for ACT for managing TTM, skin picking, and OCD. Although no studies were identified that investigated ACT for managing anxiety in people with ABI, the review highlights issues for consideration when applying ACT in this population.

The potential impact of mindfulness on exposure and extinction learning in anxiety disorders

Mindfulness based approaches have shown promise in the treatment of various anxiety disorders. However, further research is needed to more precisely elucidate mechanisms of action through which mindfulness practice may enhance treatment for anxiety. Given centrality of exposure-based procedures in the treatment of anxiety, it is important to consider ways in which mindfulness may affect exposure and extinction processes. In fact, numerous findings in the basic science of extinction point to the possible ways in which mindfulness may facilitate extinction learning. The present paper aims to critically review the literature surrounding mindfulness and extinction learning in order to more fully explore the ways in which mindfulness-based treatments may positively impact exposure and extinction processes in the treatment of anxiety disorders. This will provide a unique synthesis of newer, acceptance-based behavior therapies with established principles of effective behavioral treatments.

The relation between childhood maltreatment and self-injury: a review of the literature on conceptualization and intervention

The following article reviews literature pertaining to the association between child maltreatment and self-injury and the ways it varies according to maltreatment type. Research supporting various mediators of the relations between different maltreatment types and self-injury is summarized. Informing mediator models, dominant theories of functionality, particularly affect regulation theories, are summarized and granted empirical support. Following from explanations of its functionality, three developmental pathways (regulatory, representational/interpersonal, and reactive/neurobiological) leading from child maltreatment to self-injury are presented within an organizational model of psychopathology. Understanding the deviations in these pathways that perpetuate self-injury helps to inform intervention approaches that forge pathways perpetuating resilience instead. Three psychosocial treatments (i.e., Dialectical Behavior Therapy [DBT], Trauma-Focused Cognitive-Behavioral Therapy [TF-CBT], and Acceptance and Commitment Therapy [ACT]) were chosen for review, based upon their accumulating evidence bases, as well as upon the relevance of their core components in correcting or compensating for trauma-related developmental deviations.

Epidemiology and management of alcohol dependence in individuals with post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is a chronic and disabling psychiatric disorder with an estimated lifetime prevalence of 7.8%. Co-morbid alcohol dependence is a common clinical occurrence with important clinical considerations. For example, in individuals with both PTSD and alcohol dependence, the symptoms of PTSD tend to be more severe, and there is evidence that these individuals are more prone to alcohol use relapse than non-co-morbid individuals. Co-morbidity of PTSD and alcohol dependence is also associated with a higher rate of psychosocial and medical problems and higher utilization of inpatient hospitalization than either disorder alone. This article highlights the epidemiology of alcohol dependence in PTSD and reviews the evidence for effective treatments. Management of these individuals requires an understanding of the epidemiology and an awareness of treatment interventions, which include both psychosocial treatments (e.g. Seeking Safety, Concurrent Treatment of PTSD and Cocaine Dependence, Transcend, Trauma Recovery and Empowerment Model) and pharmacotherapy (e.g. selective serotonin reuptake inhibitors [SSRIs] and topiramate). Effective treatment of co-morbid PTSD and alcohol dependence may include a combination of these psychosocial and pharmacological interventions. The key element seems to be to ensure an adequate intervention for each disorder administered collaboratively.

Mindfulness and experiential avoidance as predictors of posttraumatic stress disorder avoidance symptom severity

Mindfulness reflects an awareness of present moment experiences through an attitude of acceptance and openness (Bishop et al., 2004; Cardaciotto, Herbert, Forman, Moitra, & Farrow, 2008). Experiential avoidance, by contrast, refers to attempts to change, alter, or avoid private experiences (e.g., thoughts, feelings, sensations), and it is believed to underlie a number of psychopathologies, including PTSD (Hayes, Wilson, Gifford, Follette, & Strosahl, 1996). We were interested in the ability of mindfulness to predict the variance of PTSD avoidance symptom severity above and beyond experiential avoidance. 378 introductory psychology students were administered self-report measures of PTSD, mindfulness, experiential avoidance, thought suppression, alexithymia, and avoidant coping. Mindfulness, specifically nonjudgment of experiences, accounted for a unique portion of the variance in PTSD avoidance symptoms.
