The present study extends previous research on acceptance and commitment therapy (ACT) by using a new ACT protocol, the Fusion Management System (Dixon, 2013 in press) with a new population. Participants were 2 high functioning children with autism: an 8-year old boy and a 12 year-old girl. Using a multiple baseline design, 2 participants were exposed to 15 hours of therapy over the span of 12 weeks. Behavioral data was taken for each participant by their parent(s) on a problematic behavior that was of concern to them. Prior to and following the ACT intervention, both participants took three psychometric measures that were designed to measure ACT related processes: the Child and Adolescent Mindfulness Measure (CAMM), the Acceptance and Action Questionnaire-II (AAQ-II), and the Avoidance and Fusion Questionnaire for Youth (AFQ-Y). Following the intervention one participant improved on all measures of the ACT related processes and the other participant's score improved on the AFQ-Y and slightly deteriorated on the CAMM and AAQ-II. During the intervention phase of this study both participants' problematic behavior significantly improved. Implications of the study and future research are also discussed.

Therapist burnout is of primary concern for individuals who provide ABA therapy for those with autism or related disabilities. Prolonged high levels of work-related stress increase the risk of negative interactions and emotional exhaustion among workers. Acceptance and Commitment Therapy (ACT) may alleviate this problem. ACT has been found to decrease levels of perceived work-related stress among direct care staff. The primary purpose of the study was to evaluate whether ACT would improve positive interactions among therapists for children with autism spectrum disorder. The results indicated that the percentage of positive interactions had improved an average of 23.1% and procedural fidelity improved an average of 7% across all three participants. This study extends that of previous research by supporting the efficacy of ACT in work environments. One implication of the current study is that it could benefit the psychological well-being of ABA therapists. Future studies should examine whether ACT-exercises influence the way therapists address challenging behavior as it pertains to the quality of services delivered.

This study aimed to investigate the use of values based training with typically developing adults to affect levels of physical activity recorded by FitBit Flex technology in the form of step count. Traditional approaches have shown promise but with mixed results. Interestingly, one must look outside of behavior analysis for interventions attempting to affect control by an individual’s covert verbal behavior. Acceptance and Commitment Therapy (ACT) has been shown to be effective in various behavior change areas by using a values based approach that focuses on the control of rules and their motivative functions. An ACT training protocol (ACTr) consisting of values identification, present moment training, and committed action (goal setting) was implemented across four sessions to teach various tools in an effort to relate personal values to physical activity and create short-term and long-term goals with respect to those values. Results show small to moderate increases in physical activity during intervention with continued increases seen in follow-up. These results support the potential of using values based training to increase physical activity levels.

Det finns lite forskning kring metoder och arbete med par såväl internationellt som i Sverige. Syftet med denna studie har varit att undersöka om tillägg av upplevelsebaserade övningar med fokus på defusion bidrar till ytterligare ökning av den relationella tillfredsställelsen jämfört med traditionell familjerådgivning. Defusion är en av processerna i Acceptance and Commitment Therapy. Studien har bestått av en undersökningsgrupp (n=16, 8 par) som erhållit en work-shop med upplevelsebaserade övningar med fokus på defusion samt en kontrollgrupp (n=16, 8 par). Vi valde att undersöka följande: Finns det en skillnad i utfall vad gäller relationell tillfredsställelse mellan grupperna efter tre sessioner? Finns det en skillnad mellan grupperna vad gäller utfall efter tre sessioner vad gäller: anpassningsförmåga rörande områdena enighet, sammanhållning, tillfredsställelse samt känslouttryck, frekvens av valideringsbeteenden samt grad av kognitiv sammanblandning och upplevelsebaserat undvikande. Resultatet visar på en signifikant skillnad i undersökningsgrupp jämfört med kontrollgrupp avseende sammanhållning samt tillfredsställelse i relationen. Måttliga effektstorlekar har också kunnat påvisas. Slutsatsen som drogs var att denna typ av tillägg vid behandling av par visar lovande resultat och bör väcka intresse för ytterligare forskning och metodutveckling.

Objectives. Mindfulness and acceptance-based therapies are becoming increasingly popular in practise and meta-analyses have been conducted to evaluate their effects on a range of mental health difficulties. The purpose of this review was to evaluate the evidence base for mindfulness and acceptance-based therapies in the treatment of distressing auditory hallucinations. Method. Five electronic databases were searched in addition to an internet search engine. Authors of included studies were contacted and reference lists were reviewed. Quality criteria were developed and studies were rated independently by three raters. Results. Nine studies met the inclusion criteria; four controlled studies and five case studies. There was substantial variation in study design and outcomes. Overall, the quality of the studies was poor. Reductions in hallucination-related distress, belief conviction, cognitive appraisals and hallucination proneness were noted. Participants’ ability to respond mindfully to hallucinations increased. Conclusion. Although the results of this review suggest that mindfulness and acceptance-based therapies may result in several beneficial effects, the quality of these studies was poor and the results are likely to have been subject to considerable bias. More research is needed before such therapies can be considered evidence-based treatments for distressing hallucinations. Suggestions for future research are made.

Behavior analysts who study verbal behavior theorize that people derive relationships between stimuli - forming stimulus classes such that psychological functions transfer among stimuli and therefore affect behavior. Verbal processes are thought to play a role in cancer patients' behavioral flexibility. The current study examined if an analogue intervention produced changes in relations between health-relevant stimuli from pre- to post-test in patient and student samples. A matching-to-sample (MTS) task required participants to form three 4-member classes that included health, treatment, or neutral terms. Participants next listened to either an acceptance-based or a control-based rationale and therapy exercise, or a distracter task. Then, they were re-exposed to the MTS task. Latencies and accuracies for learning each class as well as between condition differences were examined. Finally, changes in ratings of stimuli from pre to post analogues were measured. Differences in stimuli ratings were seen in the student sample, reflecting transfer of function and some reduction in responsiveness to stimuli following intervention, but overall no learning performances are found. Discussion explores the consistency of the findings with acceptance and commitment therapy (ACT) theory in light of the seemingly lack of findings.

Freely choosing a life direction, or flexible valuing, is a core component of acceptance and commitment therapy (ACT). Initial research suggests that valuing behavior may contribute to psychological well-being, but has been stymied by a lack of an efficient measure. The current study examined the psychometric characteristics of a new measure of flexible valuing, the Meta-Valuing Measure (MVM), in a sample of 532 undergraduates. Exploratory factors analysis revealed 3 orthogonal factors, Valuing (α = .94), Freedom from Values Conflict (α = .92), and Flexibility in Valuing (α = .73). The majority of expected relationships with other constructs were significant including those with measures of values, mindfulness, quality of life, experiential avoidance, and psychological distress.

Intimate partner violence (IPV) is a serious public health concern. Existing interventions for male IPV offenders (i.e., Duluth Model with CBT principles) have shown small-to-negligible effects in reducing future perpetration of violence and have high dropout rates. Offenders who fail to complete treatment, or are deemed to be at “high risk”, are sent to jail. Efficacious and acceptable interventions for incarcerated IPV offenders are needed. The objective of this dissertation study was to test the feasibility of implementing an Acceptance and Commitment Therapy (ACT) skills group with incarcerated IPV offers. The ultimate goal of ACT is to help individuals make behavioral choices in the service of their values, despite the presence of unwanted internal experiences, through the use of acceptance and mindfulness skills. The specific aims of the study were: 1) to examine post-treatment effects in the targeted ACT skills (i.e., present-moment awareness, acceptance, defusion, experiential avoidance), internalizing symptoms, and externalizing behaviors; and to test whether treatment effects were moderated by IPV-related criminal history severity (IPV-CHS); 2) to explore participants’ perceptions of the group; and 3) to examine whether pre-treatment IPV-CHS predicted worse ACT skills and greater symptom severity at pre-treatment. A sample of 33 court-mandated IPV offenders who participated in the 1 month ACT skills group (12 sessions, delivered 3 times per week) and who completed self-report questionnaires at pre and post treatment was used to evaluate the first two aims. The sample used to evaluate aim three consisted of 58 participants who had completed either the ACT skills group or another treatment offered at the jail at the time (treatment-as-usual) and for whom pre-treatment data were available. Quantitative results revealed that ACT did not produce significant pre to post changes in any of the outcome measures (i.e., ACT skills, internalizing symptoms, and externalizing behaviors), that IPV-CHS did not reliably moderate treatment effects, and that IPV-CHS did not predict worse ACT skills or greater symptom severity at pre-treatment. Qualitative results, however, revealed that participants viewed the ACT treatment favorably, found the material useful, and felt accepted and understood by the facilitators. The present study provides evidence for the feasibility of administering a standardized ACT-based protocol within a correctional setting. It further demonstrated that incarcerated IPV offenders perceived ACT to be an acceptable and useful treatment approach. The quantitative data, however, do not support the widespread dissemination of this ACT protocol with incarcerated IPV offenders at this time. Future research should follow-up on these discrepant findings by testing this ACT protocol with a larger sample, randomizing into ACT versus control group, including multiple follow-up time points, collecting one-year recidivism data, and exploring the effects of longer treatment and alternate forms of delivery (e.g., combination of individual and group sessions). Strengths and limitations of the study, as well as additional recommendations and directions for future research, are discussed.

Clinical perfectionism is characterized by rigidly pursuing unrealistically high standards on which self-worth is contingent and experiencing distress when these standards are not met. Because clinical perfectionism is associated with many psychological diagnoses, understanding how to treat it may help streamline available treatments. The aim of this dissertation was to test the effect of acceptance and commitment therapy (ACT), a cognitive-behavioral therapy, on 53 individuals with clinical perfectionism. Participants in the ACT group received 10 therapy sessions and those in the control group were on a waitlist for 14 weeks. The first study supported the effectiveness of ACT relative to the waitlist control group with respect to perfectionism severity, quality of life, and general symptom distress. The second study showed changes in psychological inflexibility and self-compassion explained improvements in quality of life and concern over mistakes, respectively. It also found a variable effect of baseline psychological inflexibility on response to treatment depending on the outcome tested. In contrast, average self-compassion was generally associated with better outcomes in ACT. Neurological results from the third study suggest receiving ACT was associated with greater cognitive efficiency while performing error-prone tasks and decreased responsivity to emotionally meaningful stimuli. In addition, changes in brain activation were not linked to changes in self-report outcomes. Collectively, this dissertation examined not only the efficacy of an intervention focused on a maladaptive behavioral pattern like clinical perfectionism but also how and for whom such a therapy works.
