Evaluating posttraumatic stress in young adult cancer survivors: Implications of revised DSM-5 traumatic event criteria.

OBJECTIVE: The Diagnostic and Statistical Manual for Psychiatric Diagnoses (DSM-5) significantly narrowed conditions under which life-threatening illnesses meet qualifying traumatic event (QTE) criteria for posttraumatic stress disorder (PTSD). To investigate the impact of this change on identification of PTSD in young adult cancer survivors (YACS), we compared prevalence of QTE exposure using DSM-5 and earlier DSM-IV criteria. METHODS: The Structured Clinical Interview for the DSM-5 (SCID-5) was customized for study goals and administered to a convenience sample of 250 YACS ages 18-40 followed at a single cancer center. RESULTS: The SCID-5 was well-tolerated by participants and estimated duration was brief (33 min; range 12-75). Only 35 interviews (14%) presented complex scoring questions. 168 participants (67.2%) identified cancer as their "most stressful or traumatic experience." Applying DSM-IV criteria, 227 YACS (90.8%) reported any QTEs; prevalence was significantly reduced following more restrictive DSM-5 QTE criteria, with only 124 YACS (49.6%) reporting ≥1 QTE (z = -9.68, p < 0.001). CONCLUSIONS: The SCID-5 can be successfully adapted to assess QTEs in YACS following both DSM-IV and DSM-5 criteria. DSM-5 criteria significantly limit prevalence of QTE exposures compared with DSM-IV. As the majority of YACS identify cancer as their most stressful life event, it is critically important to investigate its impact on their psychological functioning. Until more is known about how PTSD symptoms may arise after cancer, clinicians and researchers should adapt PTSD assessments to systematically evaluate the role of cancer as a traumatic event that may lead to PTSD symptoms in YACS.

Learning gains from a one-day training in acceptance-based behavior therapy.

The primary method of training for individual licensed mental health professionals is continuing education (CE). Despite the promise of CE as a vehicle for training clinicians in evidence-based practices, only a handful of studies have examined the efficacy of trainings delivered in the CE context. Moreover, these studies have focused on a few very specific therapeutic approaches. There is a growing body of evidence supporting Acceptance-based Behavior Therapy (ABBT) as a treatment for generalized anxiety disorder (GAD) and related disorders. Training workshops aimed at disseminating ABBT are regularly conducted across and outside the United States, yet the effectiveness of these trainings is unknown. The goal of this study was to examine learning outcomes among licensed mental health professionals following a six-hour CE training in ABBT. Data were collected at baseline, post-training, and at three-month follow-up. Participants demonstrated a statistically significant increase in learning on an ABBT Knowledge Questionnaire and in their coded responses to client scenarios from baseline to follow-up, although there was a significant decline in knowledge between post and follow-up. Beyond baseline ABBT knowledge, attitude towards evidence-based practice was the only predictor of change in knowledge over time.

A randomized controlled pilot study evaluating Worry Less, Live More: The Mindful Way Through Anxiety Workbook.

Effective interventions for generalized anxiety exist, but barriers to treatment prevent their broad dissemination. Commercially available self-help materials may help bridge this gap, but few have been empirically evaluated. This study compared self-reported change in generalized anxiety symptomology and associated problems between community members with excessive worry who were randomly assigned to receive the Worry Less, Live More: The Mindful Way through Anxiety Workbook (n = 35) and those in a delayed condition (n = 29). Participants in the workbook condition reported significantly greater reductions between baseline and 11-week follow-up in self-reported worry (η2 =.15), general anxiety/tension (η2 =.13), and anxiety (η2 =.24) than those in the delayed condition, although no statistically significant differences across condition on changes in depression, functional impairment or acceptance were detected. This pilot study provides support for continued research examining the efficacy of acceptance-based behavioral therapy delivered in a self-help format.

The relationship between substance use, experiential avoidance, and personally meaningful experiences.

Background: High rates of substance use among college students have been associated with a wide range of detrimental consequences. Psychological inflexibility, characterized by both experiential avoidance and a disconnection with personally meaningful values, is proposed to contribute to the development and maintenance of substance misuse. Objectives: This study explored the unique contribution of experiential avoidance and four different values dimensions (i.e., importance, consistency, effort, and intrinsic motivation) on substance use and related problems accounting for the known predictors of gender and drinking motives. Method: Zero-inflated regression was used to analyze predictors of substance use and related problems among 233 college students. Results: Controlling for gender and drinking motives, stronger values importance was predictive of lower rates of alcohol use problems. Less behavioral consistency with values predicted marijuana abstinence, less frequent use of marijuana, and less frequent use of illicit drugs. Although there was little evidence for a unique association between experiential avoidance and substance use or substance-related problems in this sample, coping and enhancement motives predicted alcohol use problems and illicit drug use. Conclusion/Importance: These findings offer preliminary support for prevention and intervention efforts aimed at enhancing engagement in values activities and reducing substance use as a form of affect regulation in this population.

Surviving and Thriving During Stress: A Randomized Clinical Trial Comparing a Brief Web-Based Therapist-Assisted Acceptance-Based Behavioral Intervention Versus Waitlist Control for College Students.

The high rates of anxiety in college students and the many barriers to accessing evidence-based care in communities and on campuses indicate a clear need to explore ways to increase access to evidence-based treatments. Web-based interventions and preventions are one way to bridge this gap; they hold the potential to decrease mental health disparities and enhance student functioning. The current RCT examined the acceptability and efficacy of a 3-session web-based therapist-assisted acceptance-based behavioral intervention targeting anxiety (Surviving and Thriving During Stress) for college students versus a waitlist (WL) control condition, in a sample of racially and ethnically diverse college students. Overall, participants rated the program as helpful and acceptable. Mixed-effects regression models (MRMs) were run in SPSS to examine the effects of time, condition, and Condition × Time on outcomes and hypothesized mechanisms. Significant Condition × Time interactions for general anxiety, depression, and quality of life (QOL) emerged, suggesting that SATDS participants reported significantly greater changes on these outcomes from pre- to posttreatment versus WL. However, interaction effects were nonsignificant for anxious arousal and social anxiety. MRMs examining hypothesized mechanisms revealed significant Condition × Time interactions for experiential avoidance, decentering, and values-based living. However, interaction effects were nonsignificant for mindfulness. All significant gains were maintained at 1-month follow-up, with the exception of QOL. Results contribute to the growing literature on the acceptability and efficacy of web-based approaches, and suggest these approaches can be effective for diverse college students, and may provide a unique platform to increase access to evidence-based care.

The relationship between personal growth and psychological functioning in individuals treated in a partial hospital setting.

OBJECTIVES: We examined whether current level of personal growth and changes in personal growth predicted treatment response among participants in a partial hospital setting. METHOD: Patients (N = 269; aged 18-70 years, M = 33.6; 52.4% female) completed measures of personal growth initiative (PGI), valuing personal growth (VPG), and psychological functioning measures at treatment admission and discharge from a partial hospital. RESULTS: PGI and VPG were negatively associated with depression and positively associated with psychological well-being. Baseline PGI and VPG did not predict changes in psychological functioning at discharge. PGI and VPG significantly increased following treatment, and increases were associated with decreases in depression and increases in well-being over and above previously established predictors. CONCLUSIONS: Valuing personal growth for intrinsic reasons and active engagement in the personal growth process may be important characteristics to cultivate in psychotherapy as they are malleable and negatively related to depression.

Reductions in experiential avoidance as a mediator of change in symptom outcome and quality of life in acceptance-based behavior therapy and applied relaxation for generalized anxiety disorder.

As a field, we lack information about specific mechanisms that are responsible for changes that occur over the course of treatments for anxiety disorders (Kazdin, 2007). Identifying these mechanisms would help streamline evidence-based approaches, increase treatment response rates, and aid in the dissemination and implementation of evidence-based approaches in diverse contexts. The current study examined reductions in experiential avoidance (EA; Hayes, Wilson, Gifford, Follette, & Strosahl, 1996), attempts to control or eliminate distressing internal experiences, regardless of behavioral consequences, as a potential mechanism of change in participants with a principal diagnosis of generalized anxiety disorder (GAD) receiving either acceptance-based behavior therapy (ABBT) or applied relaxation (AR). Participants' EA scores across treatment on the Acceptance and Action Questionnaire (AAQ) were used to calculate slopes, which were used as predictors in a series of linear regressions. Greater change in EA across treatment significantly predicted change in worry (PSWQ) and quality of life (QOLI) across both treatments. These results contribute to the body of literature on common mechanisms of change across traditional CBTs and mindfulness and acceptance-based approaches.

The Mindful Way Through the Semester: Evaluating the Impact of Integrating an Acceptance-Based Behavioral Program Into a First-Year Experience Course for Undergraduates.

Preventing and reducing depression in first-year college students are crucial areas in need of attention and resources. Programs that are cost-effective and time-efficient, that have replicable benefits across samples, are sorely needed. This study aims to examine whether a previously studied acceptance-based behavioral (ABBT) program, the Mindful Way Through the Semester (MWTS), is effective in comparison to a control condition at decreasing levels of depression and enhancing acceptance and academic values when integrated into a first-year undergraduate experience course. The current study also sought to examine the association between change in acceptance, mindfulness practice, and values practice on outcomes. Two hundred thirteen students were assigned to either the MWTS workshop condition or the control condition (in which the first-year experience curriculum as usual was received). Results revealed that the workshop condition produced larger decreases in depression over the course of the semester relative to the control condition, but only for participants endorsing higher levels of depression at baseline. Further, for participants in the workshop condition, changes in depression were negatively associated with changes in acceptance (i.e., larger increases in acceptance associated with larger decreases in depression), an association that was not statistically significant in the control group. Lastly, for participants in the workshop condition who endorsed higher levels of depression at baseline, mindfulness and values practice was associated with greater reductions in depression. Implications of these findings for future interventions are discussed.

Acceptance and Body Dissatisfaction: Examining the Efficacy of a Brief Acceptance Based Intervention for Body Dissatisfaction in College Women.

BACKGROUND: Body dissatisfaction among college women is concerning given its high prevalence and associated negative consequences. While cognitive-behavioral approaches to reducing body dissatisfaction have considerable support, it may be beneficial to target the problematic relationship that some individuals have with their internal experiences. AIMS: To examine the relative efficacy of an acceptance-based compared to a cognitive restructuring approach to targeting body dissatisfaction. METHOD: College women were randomly assigned to an acceptance (n = 21), cognitive restructuring (n = 21) or a neutral comparison condition (n = 24). Participants completed a body dissatisfaction challenge postintervention and their dissatisfaction, distress about body-related thoughts and emotions, and the extent they felt defined by their outward appearance were measured. RESULTS: Both approaches provided a protective effect against decreases in body satisfaction and related feelings. CONCLUSION: Acceptance and CBT approaches to treating body dissatisfaction are worthy of future investigation.

Interpersonal Problems, Mindfulness, and Therapy Outcome in an Acceptance-Based Behavior Therapy for Generalized Anxiety Disorder.

OBJECTIVE: To better understand the role interpersonal problems play in response to two treatments for generalized anxiety disorder (GAD); an acceptance-based behavior therapy (ABBT) and applied relaxation (AR), and to examine how the development of mindfulness may be related to change in interpersonal problems over treatment and at follow-up. METHOD: Eighty-one individuals diagnosed with GAD (65.4% female, 80.2% identified as white, average age 32.92) were randomized to receive 16 sessions of either ABBT or AR. GAD severity, interpersonal problems, and mindfulness were measured at pre-treatment, post-treatment, 6-month follow-up, and 12-month follow-up. RESULTS: Mixed effect regression models did not reveal any significant effects of pre-treatment interpersonal problems on GAD severity over treatment. After controlling for post-treatment GAD severity, remaining post-treatment interpersonal problems predicted 6- but not 12-month GAD severity. Participants in both conditions experienced a large decrease in interpersonal problems over treatment. Increases in mindfulness over treatment and through follow-up were associated with decreases in interpersonal problems, even when accounting for reductions in overall GAD severity. CONCLUSIONS: Interpersonal problems may be an important target of treatment in GAD, even if pre-treatment interpersonal problems are not predictive of outcome. Developing mindfulness in individuals with GAD may help ameliorate interpersonal difficulties among this population.

An investigation of the efficacy of acceptance-based behavioral therapy for academic procrastination.

Procrastination among college students is both prevalent and troublesome, harming both academic performance and physical health. Unfortunately, no "gold standard" intervention exists. Research suggests that psychological inflexibility may drive procrastination. Accordingly, interventions using acceptance and mindfulness methods to increase psychological flexibility may decrease procrastination. This study compared time management and acceptance-based behavioral interventions. College students' predictions of how much assigned reading they should complete were compared to what they did complete. Procrastination, anxiety, psychological flexibility, and academic values were also measured. Although a trend suggested that time management intervention participants completed more reading, no group differences in procrastination were revealed. The acceptance-based behavioral intervention was most effective for participants who highly valued academics. Clinical implications and future research are discussed.

Decentering as a potential common mechanism across two therapies for generalized anxiety disorder.

OBJECTIVE: The purpose of this study was to examine decentering as a potential mechanism of action across 2 treatments for generalized anxiety disorder: an acceptance-based behavioral therapy (ABBT) and applied relaxation (AR). METHOD: Sixty-four individuals who completed at least half of the 16 total sessions of either ABBT or AR (65.6% female; 79.7% identified as White; average age = 34.41 years) completed measures of decentering (Experiences Questionnaire) and of symptoms of anxiety (Depression Anxiety Stress Scale-Stress subscale) at 5 time points over the course of therapy, and a measure of worry (Penn State Worry Questionnaire) at pre- and posttreatment. RESULTS: Initial growth curve models showed that decentering increased significantly over therapy (z = 7.09), and this increase was associated with a decrease in worry symptoms (Penn State Worry Questionnaire) at posttreatment (z = -8.51). The rate of change did not significantly vary across treatments, Δχ2/Δdf = 0.16/1, p = .69. Further, a series of bivariate latent difference score models indicated that the best-fitting model was one in which decentering was a leading indicator of change in symptoms (DASS-Stress). Allowing this coupling to vary across treatments did not significantly improve the fit of the model, Δχ2/Δdf = 0.71/1, p = .40. CONCLUSIONS: In this sample, results suggest that increased decentering was associated with decreases in anxiety and that changes in decentering appear to precede changes in symptoms within both ABBT and AR, indicating that decentering may be an important common mechanism of action.

Association Between Specific Depression Symptoms and Glycemic Control Among Patients With Comorbid Type 2 Diabetes and Provisional Depression.

OBJECTIVE: To determine whether specific depression symptoms are associated with glycemic control independent of potential demographic and clinical covariates among primary care patients with comorbid type 2 diabetes and provisional threshold or subthreshold depression. METHOD: We examined a convenience sample of patients diagnosed with type 2 diabetes and provisional threshold or subthreshold depression (N = 82) at 2 family health centers. Cases were identified using a population-based registry of patients diagnosed with type 2 diabetes (ICD-9 codes 250.00 for controlled type 2 diabetes and 250.02 for uncontrolled type 2 diabetes). Data from patients with a primary care provider appointment from the beginning of April 2011 through the end of June 2012 and with at least one 9-item Patient Health Questionnaire (PHQ-9) depression screener and a glycated hemoglobin A1c (HbA1c) laboratory test between 2 weeks before and 10 weeks after PHQ-9 screening were eligible for inclusion. We defined provisional threshold or subthreshold depression using PHQ-9 scoring criteria, which were designed to yield provisional diagnostic information about major depressive disorder based on DSM-5 diagnostic criteria. RESULTS: Patients reporting higher severity of sleep problems on the PHQ-9 had significantly higher HbA1c levels (mean = 8.48, SD = 2.17) compared to patients reporting lower severity or absence of this symptom (mean = 7.19, SD = 1.34, t 48.88 = -3.13, P = .003). Problems with sleep contributed unique variance on glycemic control (ß = 0.27, P = .02) when controlling for potential clinical and demographic covariates, with those reporting more sleep difficulties having higher HbA1c levels. CONCLUSIONS: For patients with type 2 diabetes and provisional threshold or subthreshold depression, it may be prudent to aggressively address sleep problems as a potential mechanism toward improving diabetes control.

Relationships Between Amount of Post-Intervention of Mindfulness Practice and Follow-up Outcome Variables in an Acceptance-Based Behavior Therapy for Generalized Anxiety Disorder: The Importance of Informal Practice.

Because most behavioral treatments are time-limited, skills and practices that foster long-term maintenance of gains made during treatment are of critical importance. While some studies have found mindfulness practice to be associated with improvements in outcome variables over the course of treatment (Vettese et al., 2009), very little is known about the effects of continued mindfulness practice following treatment termination. The current study examined the relationships between separate single item measurements of three types of mindfulness practices (formal, informal, and mindfulness of breath in daily life) and longer-term outcomes in worry, clinician-rated anxiety severity, and quality of life following treatment with an acceptance-based behavior therapy (ABBT) for Generalized Anxiety Disorder (GAD) in two separate treatment studies. Results from Study 1 showed that at 9-month follow-up, amount of informal mindfulness practice was significantly related to continued beneficial outcomes for worry, clinician-rated anxiety severity, and quality of life. Similarly, in Study 2, at 6-month follow-up informal mindfulness practice was significantly related to continued beneficial outcomes for anxiety severity and worry, and at 12-month follow-up informal mindfulness practice was significantly related to continued beneficial outcomes for quality of life and worry, and mindfulness of breath was significantly related to quality of life. When results from the final time point in both studies were combined, informal practice was significant related to all three outcome variables, and mindfulness of breath was significantly related to worry and quality of life. Formal practice was not significantly related to outcomes in either study, or in the combined sample. These findings support the further study of informal mindfulness practices as important tools for continued beneficial clinical outcomes following treatment for people with a principal diagnosis of GAD.

The Mindful Way Through the Semester: An Investigation of the Effectiveness of an Acceptance-Based Behavioral Therapy Program on Psychological Wellness in First-Year Students.

First-year students in higher education deal with an increasing number of mental health issues. Cost-effective and time-efficient programs that ease transitions and reduce risk of depression are needed. To date, programs informed by both cognitive-behavioral and acceptance-based-behavioral therapy (ABBT) approaches have produced some positive outcomes, but methodological limitations limit their utility. The aim of the present study was to address some of these limitations, by developing and preliminary testing the efficacy of a one-session ABBT intervention with first-year undergraduates and first-year law students. Ninety-eight first-year students were randomly assigned to receive either a single-session 90-min ABBT workshop within their first month of school or to a waitlist control condition. Students who received the intervention reported significantly less depression and more acceptance. Moreover, increase in acceptance over the course of the semester was associated with reductions in depression. Implications of these findings for future interventions are discussed.

Investigating cognitive flexibility as a potential mechanism of mindfulness in Generalized Anxiety Disorder.

BACKGROUND AND OBJECTIVES: Research suggests mindfulness-based treatments may enhance efficacy of CBT for Generalized Anxiety Disorder (GAD). One hypothesized mechanism of mindfulness is cognitive flexibility; however, research findings to date are mixed as to a) whether cognitive inflexibility represents a characteristic of GAD, and b) whether mindfulness impacts cognitive flexibility. It is proposed that limitations in study methodology may partially account for these mixed findings. The present study investigated cognitive flexibility as a potential mechanism of mindfulness in a sample with elevated GAD symptoms using a modified emotional Stroop switching task while attempting to control for limitations of previous research. The purpose of the study was: 1) to explore cognitive inflexibility as a potential characteristic of GAD, and 2) to examine whether a brief mindfulness induction has measurable impact on cognitive flexibility. METHODS: A total of 66 participants (53 with elevated GAD symptoms, and 13 non-anxious) were randomized to a mindful-breathing, music-assisted relaxation, or thought wandering condition prior to completing an emotional Stroop and emotional Stroop switching task. RESULTS: Results suggest that GAD may be characterized by an inflexible style of responding, and exposure to mindfulness and relaxation result in partial improvements in cognitive flexibility. LIMITATIONS: Limitations of this study include small sample size, brief induction period, and use of an analog sample. CONCLUSIONS: The present findings suggest that mindfulness may be associated with partial improvement in cognitive flexibility.

Mindfulness and acceptance-based behavioral therapies for anxiety disorders.

This article presents a brief conceptual overview of acceptance-based behavioral therapies (ABBTs) for anxiety disorders, followed by a review and summary of the recent efficacy studies of ABBTs for anxiety and comorbid disorders. We discuss clinical implications, including the importance of targeting reactivity and experiential avoidance in interventions for anxiety disorders through the use of mindfulness and other acceptance-based strategies, as well the encouragement of engagement in meaningful activities or valued action. We also address future directions for research, such as expanding research to include more randomized control trials comparing ABBTs for specific anxiety disorders to other active treatments, examining mechanisms of change, exploring adaptations in different care-delivery contexts, as well as determining the applicability of these approaches to clients from marginalized or non-dominant statuses.

A contemporary view of applied relaxation for generalized anxiety disorder.

Applied relaxation (AR), originally developed by Lars-Göran Öst, is a long-standing, efficacious treatment for generalized anxiety disorder (GAD). While newer treatments are continuing to be developed, AR remains one of the most efficacious treatments for GAD. However, AR has received less in-depth attention more recently, particularly in terms of potential mechanisms of action. This article is written to honor the development and history of AR and to highlight the ways that it has continued to be adapted. In this article, AR treatment strategies are presented, which include: noticing early signs of anxiety, learning relaxation skills, and applying relaxation at the first sign of anxiety. Then, additional adaptations to AR are presented along with recommendations of how AR may be enhanced by understanding potential mechanisms of change. Finally, recommendations are made for the continued evolution of AR as a powerful and efficacious treatment for GAD.

A randomized clinical trial comparing an acceptance-based behavior therapy to applied relaxation for generalized anxiety disorder.

OBJECTIVE: To examine whether an empirically and theoretically derived treatment combining mindfulness- and acceptance-based strategies with behavioral approaches would improve outcomes in generalized anxiety disorder (GAD) over an empirically supported treatment. METHOD: This trial randomized 81 individuals (65.4% female, 80.2% identified as White, average age 32.92) diagnosed with GAD to receive 16 sessions of either an acceptance-based behavior therapy (ABBT) or applied relaxation (AR). Assessments at pretreatment, posttreatment, and 6-month follow-up included the following primary outcome measures: GAD clinician severity rating, Structured Interview Guide for the Hamilton Anxiety Rating Scale, Penn State Worry Questionnaire, Depression Anxiety Stress Scale, and the State-Trait Anxiety Inventory. Secondary outcomes included the Beck Depression Inventory-II, Quality of Life Inventory, and number of comorbid diagnoses. RESULTS: Mixed effect regression models showed significant, large effects for time for all primary outcome measures (ds = 1.27 to 1.61) but nonsignificant, small effects for condition and Condition × Time (ds = 0.002 to 0.20), indicating that clients in the 2 treatments improved comparably over treatment. For secondary outcomes, time was significant (ds = 0.74 to 1.38), but condition and Condition × Time effects were not (ds = 0.004 to 0.31). No significant differences emerged over follow-up (ds = 0.03 to 0.39), indicating maintenance of gains. Between 63.3 and 80.0% of clients in ABBT and 60.6 and 78.8% of clients in AR experienced clinically significant change across 5 calculations of change at posttreatment and follow-up. CONCLUSION: ABBT is a viable alternative for treating GAD. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

An Acceptance-Based Behavioral Therapy for Individuals with Generalized Anxiety Disorder.

In response to clinical observations and research findings that individuals with Generalized Anxiety Disorder are reactive to their internal experiences, avoid and suppress painful emotions, thoughts, and sensations, and limit their involvement in meaningful activities, an Acceptance Based Behavioral Therapy (ABBT) was developed to specifically target these responses. ABBT incorporates acceptance and mindfulness strategies with more traditional behavior therapy techniques. Specifically, ABBT uses mindfulness and acceptance approaches as an alternate response to the rigid, avoidant responses characteristic of GAD. Likewise, therapy focuses on identifying and enacting behaviors that are congruent with what is personally meaningful to the client rather than engaging in actions that are motivated by avoidance of anxiety. This article provides a case conceptualization from an ABBT perspective for "William," the composite client presented in Robichaud (this issue). The article goes on to demonstrate how an ABBT approach to treatment may unfold session-by-session for "William."
