Thought-shape fusion in residential eating disorder treatment: Cognitive defusion as a mediator between thought-action fusion and treatment outcome.

An understudied cognitive bias within eating disorder (ED) psychopathology is Thought-Shape Fusion (TSF), which involves irrational beliefs about the likelihood and moral implications of feared outcomes related to shape, weight, and food. This phenomenon has received less attention within the context of ED treatment, with little known about potential processes of change to address TSF and ultimately promote ED recovery. We propose cognitive defusion as a process of change, a metacognitive process that emphasizes observing thoughts objectively rather than appraising thoughts as absolute truth. We explored whether cognitive defusion, that is, reductions in body image-related cognitive fusion, mediated the relationship between trait-level TSF and treatment outcomes in a transdiagnostic ED sample of adult and adolescent females (N = 130) presenting to residential care. We found that reductions in body image-related cognitive fusion mediates the association between trait-level TSF at baseline and ED severity at discharge. However, when the sample was separated into adolescent and adult subgroups, these results only remained significant for adolescents. These findings underscore the relevance of targeting cognitive defusion as a potential mechanism to address the impact of trait levels of TSF cognitions on ED psychopathology.

Acceptance and commitment therapy versus progressive relaxation training for misophonia: Randomized controlled trial protocol, interventions, and audiological assessments.

BACKGROUND: Misophonia is a disorder characterized by an intense emotional reaction to specific sounds, often leading to significant distress and impairment in daily functioning. Acceptance and commitment therapy (ACT) is a promising psychotherapy for treating misophonia, but has only been previously tested in case studies. This paper presents a protocol for the first randomized controlled trial (RCT) assessing the efficacy and feasibility of ACT supplemented by audiological interventions for misophonia versus progressive relaxation training (PRT). METHODS: The outlined protocol is a RCT with 60 adults with misophonia. After undergoing a comprehensive psychological and audiological evaluation, participants were randomly assigned to ACT (n = 30) or PRT (n = 30). All participants completed clinician-administered and self-report assessments at baseline, post-intervention, 3-month follow-up, and 6-month follow-up. The primary outcome was misophonia severity and impairment measured via clinical interview. Secondary outcomes included disgust, anger, sensory sensitivities, well-being, distress, and psychological flexibility. DISCUSSION: This paper outlines the rationale of using ACT supplemented by audiological methods for misophonia with the novel therapeutic target of enhancing psychological flexibility. The results of this randomized controlled trial will help determine if ACT is an efficacious and acceptable treatment for misophonia. This trial will also help clarify active psychological mechanisms of misophonia, and assess whether this combination of psychological and audiological services can effectively help individuals with misophonia.

Scoping Review of Acceptance and Commitment Therapy for Obsessive-Compulsive Disorder in Iran.

Acceptance and commitment therapy (ACT) for obsessive-compulsive disorder (OCD) has been found efficacious in randomized clinical trials (RCTs), but the two widely known RCTs were conducted within the United States with predominantly White samples. Research that evaluates treatments like ACT for OCD outside the typical Western cultures is needed. The current scoping review summarizes the key characteristics and findings from 18 RCTs that evaluated ACT for OCD in Iran. These RCTs are largely unknown in the broader scientific literature despite representing the vast majority of ACT for OCD trials, in part because the majority are published in Persian. The preponderance of RCTs treated participants in groups, and most protocols did not include exposure exercises. Of 18 trials, 5 were single sex. Use of selective serotonin reuptake inhibitors (SSRIs) was common with all participants on stable doses at pretreatment in many of the trials. Methodological quality was low to medium. ACT was inconsistent against nontraditional comparison conditions, slightly favorable to empirically validated treatments, and favorable compared with the waitlist and SSRIs. The process of change data indicated that ACT increased the psychological flexibility more than cognitive behavior therapy or SSRIs. These results highlight that findings on ACT for OCD from Western populations replicate and generalize to individuals in Iran. These findings also offer insights gained from studying ACT in Iran and significantly expand the literature based on ACT for OCD that can be integrated into scholarship by all researchers.

Investigating an Acceptance and Commitment Therapy-Based Exposure Therapy Intervention in Treatment-Refractory OCD and Related Disorders: Changes in Psychological Flexibility, Treatment Engagement, and Treatment Perceptions.

While exposure therapy is the most effective psychological treatment for obsessive-compulsive disorder (OCD), anxiety, and traumatic stress-related disorders, it is not universally effective, indicating a need for further treatment optimization. This study investigated a shift in approach to exposure therapy with 29 treatment-refractory adults in an OCD clinic not responding to standard treatment, comprising habituation-based exposure therapy. Participants completed standard exposure as a continuation of standard clinic treatment, followed by an acceptance and commitment therapy (ACT) consultation session to assess psychological inflexibility processes interfering with treatment progress, and then an ACT-based exposure targeting behavior change through increasing psychological flexibility. After each exposure, participants and independent raters reported levels of psychological flexibility, rituals, distress, treatment engagement, and treatment perceptions. We observed that the shift to ACT-based exposure was associated with greater psychological flexibility, treatment engagement, treatment acceptability, and treatment preference. These findings suggest that there may be situations where ACT-based exposure has particular utility.

Serial Mediation Analysis of Psychological Inflexibility and Daytime Insomnia Rumination in the Relationship Between Dysfunctional Beliefs About Sleep and Insomnia in College Students.

Emerging research suggests that psychological inflexibility may be a factor contributing to the development and maintenance of insomnia. However, less is known about the potential cognitive pathways that may explain this relationship. In this study, we investigated the serial mediating effects of psychological inflexibility and daytime insomnia-related rumination on the association between dysfunctional beliefs and attitudes about sleep (DBAS) and insomnia symptoms. The sample included 490 college students who underwent assessments at two time points over a 1-month period. The results of our mediational tests yielded significant indirect effects, supporting the prediction that psychological inflexibility and daytime insomnia rumination serially mediate the relationship between DBAS and insomnia. The study provides insights into potential mechanisms for insomnia, emphasizing the role of psychological inflexibility in perpetuating maladaptive cognitive processes associated with insomnia. Future researchers should explore other maladaptive responses to insomnia-related concerns and distress, such as worry and safety behaviors, and replicate findings in clinically elevated insomnia samples.

An exploratory examination of delay discounting in women and girls diagnosed with an eating disorder.

Those with eating disorders (EDs) characterized by purging behaviors tend to show more impulsivity than those diagnosed with restrictive eating, who tend to show more compulsivity. Impulsive choice (i.e. a type of impulsivity) is a common factor among eating disorders that is less understood. Delay discounting is a measure of choice impulsivity, examining the decrease in value of delayed outcomes. In this exploratory study, we examined associations between eating disorder type, age and delay discounting among patients at a residential ED treatment center (N = 178). Our findings showed that those diagnosed with bulimia nervosa had higher delay discounting (i.e. more impulsivity) at intake compared to anorexia nervosa, binge eating disorder, and other eating types but there were no significant differences. Those diagnosed with bulimia nervosa, as well as those with ARFID and unspecified ED showed a preference for delayed rewards at discharge, but there were no significant differences among ED types. Moderation analyses showed that age, ED type, nor the interaction did not significantly predict delay discounting at intake or discharge. To conclude, those with bulimia nervosa demonstrate less impulsive choice at discharge from a residential ED treatment center. However, additional research is needed given the variability of sample sizes in this study.

Neurocognitive functioning in adults with trichotillomania: Predictors of treatment response and symptom severity in a randomized control trial.

Trichotillomania (TTM) is associated with impairments in response inhibition and cognitive flexibility, but it is unclear how such impairments relate to treatment outcome. The present study examined pre-treatment response inhibition and cognitive flexibility as predictors of treatment outcome, change in these domains from pre-to post-treatment, and associations with TTM severity. Participants were drawn from a randomized controlled trial comparing acceptance-enhanced behavior therapy (AEBT) to psychoeducation and supportive therapy (PST) for TTM. Adults completed assessments at pre-treatment (n = 88) and following 12 weeks of treatment (n = 68). Response inhibition and cognitive flexibility were assessed using the Stop Signal Task and Object Alternation Task, respectively. Participants completed the MGH-Hairpulling Scale. Independent evaluators administered the NIMH-Trichotillomania Severity Scale and Clinical Global Impressions-Improvement Scale. Higher pre-treatment TTM severity was associated with poorer pre-treatment cognitive flexibility, but not response inhibition. Better pre-treatment response inhibition performance predicted positive treatment response and lower post-treatment TTM symptom severity, irrespective of treatment assignment. Cognitive flexibility did not predict treatment response. After controlling for age, neither neurocognitive variable changed during treatment. Response inhibition and cognitive flexibility appear uniquely related to hair pulling severity and treatment response in adults with TTM. Implications for treatment delivery and development are discussed.

An Overview of Research on Acceptance and Commitment Therapy.

This review summarized recent systematic reviews and meta-analyses on randomized controlled trials evaluating acceptance and commitment therapy (ACT). Although the strength of evidence varies, overall there is plausible evidence for the efficacy of ACT for a wide range of areas including depression, anxiety disorders, obsessive-compulsive and related disorders, psychosis, substance use disorders, chronic pain, coping with chronic health conditions, obesity, stigma, and stress and burnout. ACT is also efficacious when delivered in digital self-help formats. Reviews of mediation research indicate ACT works through increasing psychological flexibility.

Discussing Patient Emotions in Audiology: Provider Experiences With the Implementation Process of Hearing Loss Psychological Inflexibility Screenings.

PURPOSE: This study aimed to investigate barriers and facilitators experienced by clinical educators and graduate students when talking with patients about difficult emotions and thoughts related to their hearing. METHOD: A longitudinal observational design was used and an Implementation Research Logic Model guided the process. Five clinical educators and five graduate students participated in the study. Participants completed pre- and postmeasures and attended individual debriefing sessions during the 8-month study period. RESULTS: Four themes emerged from the debriefing sessions: (a) learning process, (b) confidence, (c) barriers, and (d) supervision. Participants described that the Acceptance and Action Questionnaire-Managing Child Hearing Loss and Acceptance and Action Questionnaire-Adult Hearing Loss served as a reminder to ask about patients' internal barriers and increased awareness of their discomfort in talking about patient emotions. Participants also described barriers and struggles related to supporting students in gaining counseling skills. CONCLUSIONS: Screening for internal challenges helped clinicians remember to talk with patients about their difficult thoughts and emotions. Clinician hesitancy to engage in conversations with patients about their emotions can interfere with opportunities for patients to share their struggles and with training student in these skills.

Examining processes of change for acceptance and commitment therapy and cognitive behavioral therapy self-help books with depressed college students.

Given the prevalence of depression, it is worthwhile to consider a variety of treatment approaches to reach as many sufferers as possible, including highly accessible formats such as self-help books. Books based in acceptance and commitment therapy (ACT) and cognitive behavioral therapy (CBT) propose to treat depression through distinct processes of change, though the degree to which these treatments are distinguishable in this format is unclear. Furthermore, it is possible that some individuals may respond better to therapeutic processes from one approach over the other based on personal preferences. We tested the effects of ACT and CBT self-help books on processes of change in a sample of 139 depressed college students in which some participants were given a choice of treatment and others were randomized. Cognitive fusion, which improved better in the ACT group, was the only process of change that distinguished the two treatments. Additionally, early improvements in cognitive fusion were associated with less depression-related stigma at posttreatment. Lastly, randomization, instead of choosing a treatment, led to greater improvements in almost all processes of change. We discuss how these findings inform personalized care, tangible differences between ACT and CBT, and effective practices for treating depression at large scale.

Self-compassion and body image inflexibility as mediators of outcomes in a residential eating disorder sample.

Eating disorders are serious mental health conditions that are accompanied by negative health outcomes, high mortality rates, impaired functioning, and comorbid mental health conditions. Despite many empirically supported interventions for eating disorders, it remains one of the most challenging mental disorders to treat, as individuals often struggle to maintain treatment gains. One method of improving our understanding of effective eating disorder treatment is to identify important processes of change to target during therapy. The aim of the current study was to test two candidate mediators of disordered eating symptom change during residential treatment: self-compassion and body image inflexibility. In the present study, women and adolescent girls (N = 132) completed a battery of measures, including eating disorder severity, self-compassion, and body image inflexibility, at admission to and discharge from a residential eating disorder facility. Our results indicated that changes in body image inflexibility and self-compassion, specifically self-judgment, were both mediators between ED symptom severity from pre- to post-treatment. These results have potential treatment implications, pointing to the possible importance of targeting body image inflexibility, self-judgment, and self-compassion while treating eating disorders.

Long-term follow-up of acceptance-enhanced behavior therapy for trichotillomania.

Acceptance-enhanced behavior therapy for trichotillomania (AEBT-TTM) is effective in reducing trichotillomania (TTM) symptoms, but the durability of treatment effects remains in question. This study analyzed 6-month follow-up data from a large randomized clinical trial comparing AEBT-TTM to an active psychoeducation and supportive therapy control (PST). Adults with TTM (N=85; 92% women) received 10 sessions of AEBT-TTM or PST across 12 weeks. Independent evaluators assessed participants at baseline, post-treatment, and 6 months follow-up. For both AEBT-TTM and PST, self-reported and evaluator-rated TTM symptom severity decreased from baseline to follow-up. TTM symptoms did not worsen from post-treatment to follow-up. At follow-up, AEBT-TTM and PST did not differ in rates of treatment response, TTM diagnosis, or symptom severity. High baseline TTM symptom severity was a stronger predictor of high follow-up severity for PST than for AEBT-TTM, suggesting AEBT-TTM may be a better option for more severe TTM. Results support the efficacy of AEBT-TTM and show that treatment gains were maintained over time. Although AEBT-TTM yielded lower symptoms at post-treatment, 6-month follow-up outcomes suggest AEBT-TTM and PST may lead to similar symptom levels in the longer term. Future research should examine mechanisms that contribute to long-term gain maintenance.

Reach, adoption, and maintenance of online acceptance and commitment therapy at a university: An implementation case study.

College students are undergoing a mental health crisis and existing clinical resources at universities may be inadequate to meet their needs. One solution to this problem could be the use of self-guided, online programs for mental health that can be easily distributed to students. A persistent issue, however, is the transition from program development to implementation of a self-guided program at campus-wide scale. We describe, in a self-narrative format, the steps taken to translate an online program we developed based in acceptance and commitment therapy, called Acceptance and Commitment Therapy Guide, from a research context to a campus-wide service at our university. We also present demographic, previous treatment, and referral data of over 1,500 student sign-ups to describe the reach of our program, how it was adopted into existing university services and systems, and how we maintained the program long term. Findings from these implementation efforts are discussed in the context of suggestions for using self-guided programs for students to fill gaps in mental health service provision in university settings.

Adding online storytelling-based acceptance and commitment therapy to antidepressant treatment for primary care patients: a randomized clinical trial.

Depression is most often treated in primary care, where the prevailing treatment is antidepressant medication. Primary care patients with depression are less likely to be exposed to psychosocial interventions, despite evidence suggesting many of these treatments are effective. An example is acceptance and commitment therapy (ACT), a behavioral treatment for depression with a growing evidence base. A self-guided ACT intervention with a peer narrative (i.e. storytelling) format was developed with the intention of creating a treatment option for primary care patients that was more accessible than traditional psychotherapy. Titled LifeStories, the online program features videos of real individuals sharing coping skills for depression based on lived experiences and key ACT principles. A total of 93 primary care patients taking antidepressants were randomized to either continued antidepressant treatment alone or antidepressant treatment plus LifeStories for 4 weeks. There were no differences over time on depression severity and psychological inflexibility. However, LifeStories led to greater improvements in quality of life and increased patients' interest in additional treatment compared to antidepressant medication alone.Clinical trial pre-registration: ClinicalTrials.gov (NCT04757961).

Increasing Pediatric Hearing Aid Use: Considerations for Clinical Practice.

PURPOSE: Hearing aid use can be variable for young children, and inconsistent wear time can undermine spoken language development. This study explored the effectiveness of hearing aid data logging (DL) awareness and coaching sessions on increasing hours of hearing aid use. We also collected qualitative data on challenges participants experienced managing hearing aid use. METHOD: We used a single-subject design that included three conditions, during a 6-week period, in the same order for each participant. Condition A was baseline, Condition B was DL monitoring alone, and Condition C was remote coaching calls plus DL monitoring. RESULTS: Hours of hearing aid use increased for each child from baseline to the end of the study, ranging from 1.19 to 4.4 hr. Mothers reported that the coaching calls were beneficial and helped them identify and problem-solve issues. CONCLUSIONS: Parents were able to increase hours of hearing aid use with DL awareness and coaching support. Tele-audiology offers an opportunity to provide parents with more frequent support that can be individualized based on their situation, challenges, and family needs.

Pediatric Hearing Aid Management: Experiences and Perspectives of Spanish-Speaking Parents.

PURPOSE: The purpose of the study was twofold: (a) to explore hearing aid management experiences of Spanish-speaking parents who have young children using hearing aids and (b) to explore parents' access to the Internet and perceptions about remote audiology services. METHOD: The study used a mixed methods design. Data were collected through a phone interview. RESULTS: Eleven mothers of children aged 14-60 months participated. Most of the children (9/11) had a bilateral hearing loss, and two had an additional disability. Three themes emerged for hearing aid management experiences: audiology services, routines, and emotional challenges/supports. Parents had variable levels of confidence in their skills ranging from no confidence to complete confidence, with the greatest variability for three items: (a) using the listening tube to make sure that the sound quality of the hearing aid is good, (b) removing moisture from the earmold tubing, and (c) troubleshooting problems when your child's hearing aids are not working. All participants reported having consistent Internet access and had positive perceptions about the possibility of remote audiology services. CONCLUSIONS: This study provided insights into hearing aid management experiences and perceptions of Spanish-speaking parents. Parents described variability for audiology services, routines for hearing aid use and care, and access to other parents of children with hearing loss. Spanish-speaking parents present additional elements in the hearing care process that need to be incorporated in planning. Remote services may be an opportunity to enhance access to support that could improve effectiveness of hearing aid management.

Sexual Orientation Intrusive Thoughts and Well-Being: The Mediating Role of Psychological Inflexibility.

Sexual orientation intrusive thoughts are a debilitating form of obsessive-compulsive disorder. The present study aimed to elucidate how psychological inflexibility and dysfunctional beliefs may impact the relationships of sexual orientation intrusive thoughts and obsessive-compulsive (OC) symptoms with well-being. A total of 181 undergraduate students completed measures of sexual orientation intrusive thoughts, OC symptoms, psychological inflexibility, dysfunctional beliefs, and well-being. Results indicated positive correlations between psychological inflexibility, sexual orientation intrusive thoughts, dysfunctional beliefs, and OC symptoms, along with negative correlations between well-being and sexual orientation intrusive thoughts, OC symptoms, dysfunctional beliefs, and psychological inflexibility. Psychological inflexibility acted as a mediator between sexual orientation intrusive thoughts and well-being and between OC symptoms and well-being. Dysfunctional beliefs were not a significant mediator. These results suggest that psychological inflexibility may partially explain the association between OC symptoms and well-being, pointing toward the need for future research on the impact of psychological inflexibility on well-being in the context of OC symptoms.

The role of psychological flexibility in acceptance-enhanced behavior therapy for trichotillomania: Moderation and mediation findings.

Trichotillomania is characterized by recurrent pulling out of one's hair, leading to significant hair loss and accompanied by clinically significant distress and/or functional impairment. The current study used data from a randomized controlled trial comparing the effectiveness of acceptance-enhanced behavior therapy (AEBT) to psychoeducation plus supportive therapy (PST; active control) for trichotillomania in an adult sample. The objectives were to examine the moderating and mediating influence of trichotillomania-specific psychological flexibility in treatment for trichotillomania. Participants with lower baseline flexibility performed better in AEBT than PST in terms of greater symptom reduction and quality of life. Lower baseline flexibility also predicted higher likelihood of disorder recovery in AEBT relative to PST. In addition, relative to PST, symptom reduction in AEBT was mediated by psychological flexibility, controlling for anxiety and depression. These findings suggest that psychological flexibility is a relevant process of change in the treatment of trichotillomania. Clinical implications and directions for future research are discussed.

Self-paced acceptance and commitment training reduces burden transfer, stress, and burnout in veterinary healthcare teams.

OBJECTIVE: An acceptance and commitment training (ACT) educational program targeting reaction to difficult client interactions recently demonstrated efficacy in reducing burden transfer, stress, and burnout in veterinary healthcare teams. The current noninferiority trial compared effectiveness of the original program with a self-paced version. SAMPLE: Employees of 2 corporate veterinary groups were randomized to live (n = 128) or self-paced (124) conditions. The workshop and assessments were completed by 137 (55 live and 82 self-paced). PROCEDURES: Asynchronous modules containing the same content as the original program were placed on in-house veterinary clinic learning systems. Participants of this parallel arms trial completed pretest measures of burden transfer, stress, and burnout. Following assessment, the 3-week ACT program was delivered via videoconferencing (live) or asynchronous modules (self-paced). At post-test and 1-month follow-up, measures were repeated, with added assessment of knowledge, helpfulness ratings, and usage of techniques. A subset (n = 33) of participants repeated measures 9 to 12 months as an extended follow-up. RESULTS: Program helpfulness was rated more highly by live versus self-paced participants. Self-paced showed better program retention. No differences in knowledge or use of program techniques (> 5 times daily) emerged. Relative to pretest, both conditions showed reduced burden transfer, stress, and burnout at post-test and follow-up; no differences by condition emerged. Participants completing extended follow-up maintained improvement from baseline. CLINICAL RELEVANCE: Findings suggest a learning system-based version of this program can improve occupational distress in veterinary healthcare teams, with gains maintained over time. The flexibility of this format promotes program completion and allows broader dissemination.
