The development of the Acceptance and Commitment Therapy Fidelity Measure (ACT-FM): A delphi study and field test

Assessing multidimensional fidelity in a pilot optimization trial: A process evaluation of four intervention components supporting medication adherence in women with breast cancer

Adherence to adjuvant endocrine therapy in women with breast cancer is low. We conducted a 24-1 fractional factorial pilot optimization trial to test four intervention components supporting medication adherence [text messages, information leaflet, acceptance and commitment therapy (ACT), self-management website], in the preparation phase of the multiphase optimization strategy. Guided by the National Institute of Health Behavior Change Consortium fidelity framework, we investigated fidelity of design, training, delivery, receipt, and enactment of four intervention components. Women prescribed adjuvant endocrine therapy (n = 52) were randomized to one of eight experimental conditions comprised of combinations of the four intervention components (ISRCTN: 10487576). We assessed fidelity using self-report data (4 months post-randomization), trial data, ACT session observations, behavior change technique (BCT) coding, and interviews with participants (n = 20) and therapists (n = 6). Design: Each intervention component targeted unique behavior change techniques with some overlap. Training: All 10 therapists passed the competency assessment. Delivery: All leaflets (27/27) and website (26/26) details were sent, and ACT procedural fidelity was high (85.1%-94.3%). A median of 32.5/41 (range 11-41) text messages were delivered, but a system error prevented some messages being sent to 22 of 28 participants. Receipt: Most participants [63.0% (ACT, leaflet) to 71.4% (text messages)] read all or at least some of the intervention components they were randomized to receive. Enactment was reported most positively for ACT. All intervention components demonstrated adequate fidelity. We have provided an exemplar for assessing fidelity using the National Institute of Health Behavior Change Consortium framework in the preparation phase of multiphase optimization strategy.

Acceptance and Commitment Therapy-based Lifestyle Counselling Program for people with early psychosis on physical activity: A pilot randomized controlled trial

OBJECTIVE

To evaluate the feasibility, acceptability and efficacy of an Acceptance and Commitment Therapy-based Lifestyle Counselling Program (ACT-LCP) on health outcomes of individuals with early psychosis.

METHODS

In this assessor-blinded, parallel-group pilot randomized controlled trial, 72 early psychosis patients (mean age [SD] = 30.51 [8.02], 58.3 % female) were randomized to either the ACT-LCP group or a control group. The ACT-LCP group underwent a five-week group program focusing on ACT-based motivation for healthy lifestyles, a booster session, and two follow-up calls. The control group received standard care, one lifestyle education session, and three follow-up calls. Outcomes including physical activity, autonomous motivation, psychological flexibility, mental status, and quality of life were measured at baseline, 1-week, and 12-week post-intervention. Recruitment, retention, and adherence rates were evaluated. Focus group interviews explored participants' experiences.

RESULTS

Generalized estimating equation models demonstrated that when compared to the Control group, the ACT-LCP group showed a sixfold likelihood of engaging in at least 150 min of moderate to vigorous physical activity per week (adjusted prevalence ratio = 6.28, 95 % CI [2.09-18.93], P ≤ 0.001) at 12-week post-intervention. Improvements at 12-week also included autonomous motivation (adjusted mean difference, aMD = 4.74; P < .001), psychological inflexibility (aMD = -7.69; P < .001), mental status (aMD = -6.83; P < .001), and quality of life (aMD = 0.46; P = .006). Recruitment was successful at 55.8 %, retention at 89 %, and adherence at 80.6 %. Engagement challenges were noted in focus groups.

CONCLUSIONS

The ACT-LCP is feasible and acceptable, demonstrating initial efficacy in individuals with early psychosis. Further research should refine the intervention and explore long-term impacts.

Providing Emotional Support During the Process of Multiple Sclerosis Diagnosis (PrEliMS): A Feasibility Randomised Controlled Trial

OBJECTIVES

To evaluate the feasibility and acceptability of an emotional support programme for newly diagnosed people with multiple sclerosis.

DESIGN

Three-arm, mixed methods, randomised controlled trial comparing usual care, versus usual care plus nurse-specialist support, versus usual care plus nurse-specialist support plus peer support.

PARTICIPANTS

Community-dwelling adults within two years of diagnosis or undergoing diagnosis.

INTERVENTIONS

PrEliMS involves information provision, emotional support, and strategies and techniques based on psychoeducation, Acceptance and Commitment Therapy principles, supportive listening. One version of the intervention was provided by nurse-specialists alone and the other was provided by nurse-specialists plus peer support.

MAIN MEASURES

The main outcome of interest was the feasibility of proceeding to a definitive trial, exploring recruitment rate, acceptability, completion of outcome measures (perceived stress, mood, self-efficacy, psychological impact, and service use), and signal of efficacy.

RESULTS

Of 40 participants randomised (mean age 36.2 years (SD = 14.8); 54% women; 85% with relapsing-remitting MS), 36 and 38 returned 3- and 6-month questionnaires, respectively. Participant interviews suggested the trial was largely feasible, and the intervention acceptable, with some amendments to trial procedures and intervention delivery noted. There were, however, no statistically significant differences between groups at followup for any measures, and effect-size estimates were small.

CONCLUSION

A definitive trial combining nurse-specialist and peer support adjustment to diagnosis intervention is warranted, but more work exploring the delivery and fidelity of the intervention is needed before this is pursued.

The clinical and cost effectiveness of internet-delivered self-help Acceptance and Commitment Therapy for family carers of people with dementia (iACT4CARERS): Study protocol for a randomised controlled trial with ethnically diverse family carers

BACKGROUND

Following the successful completion of feasibility and acceptability studies of internet-delivered self-help Acceptance and Commitment Therapy for family carers of people with dementia (iACT4CARERS), a full-scale randomised controlled trial (RCT) evaluating its clinical and cost effectiveness will be conducted. This paper describes the design and protocol for a multi-site, parallel, single-blind, 2-arm RCT evaluating the clinical and cost effectiveness of iACT4CARERS plus treatment-as-usual (TAU) in comparison to TAU alone for reducing anxiety in family carers of people with dementia.

METHODS

496 family carers aged ≥18 years, who are caring for a person with dementia, will be recruited from national healthcare services, general practices and community groups in England. Participants randomised to the intervention arm will receive iACT4CARERS over 12 weeks. Participants will complete outcome measures at baseline (0 weeks) and at 12-weeks and 24-weeks post-randomisation. The primary outcome and timepoint will be anxiety at 12 weeks. Secondary outcomes will include psychological flexibility, depression, and cost-effectiveness (cost per quality adjusted life years). Primary analyses will be by intention-to-treat and data will be analysed using linear mixed models. Fidelity and quality of implementation will be assessed and contextual factors associated with variation in outcomes identified in a process evaluation.

CONCLUSION

If iACT4CARERS is found to be effective and affordable, this self-help intervention, including minimal contact with minimally trained therapists, has the potential to be rolled out widely within healthcare services in the UK, reducing inequality in access to psychological services among this population.

Randomised controlled trial of a psychotherapeutic intervention to improve quality of life and other outcomes in people who repeatedly self-harm: FReSH START study protocol

BACKGROUND

Self-harm is a major public health challenge, and repeated self-harm is common in those attending hospital following an episode. Evidence suggests psychological interventions could help people who self-harm, but few definitive studies have assessed their clinical and cost-effectiveness. Repeated self-harm is associated with poor quality of life, depression, suicide and increased health service costs which justify the development of psychotherapeutic interventions tailored for people with repeated self-harm.

METHODS

FReSH START is a multicentre individually 1:1 randomised controlled trial evaluating the clinical and cost-effectiveness of standard care plus psychological therapy or standard care alone for adults (≥ 18 years) presenting at an emergency department (ED) with repeated self-harm. Recruiting 630 participants, it includes an internal pilot, economic evaluation and process evaluation. The intervention will be delivered by mental health staff working in acute settings, with experience of assessing and managing risk in people presenting to emergency services with self-harm. Staff will be trained and supervised to deliver one of three specially adapted therapies: psychodynamic interpersonal therapy, cognitive behavioural therapy or acceptance and commitment therapy. Participants allocated to the intervention will receive one of the adapted therapies according to therapist allocation for up to 6 months via 12 weekly, one to one, 45-50-min sessions. The primary outcome is quality of life measured by the Clinical Outcomes in Routine Evaluation Outcome Measure at 12 months post-randomisation. Secondary outcomes include suicidal intent, depression and cost-effectiveness. Data are collected using hospital attendance records and online/postal/telephone questionnaires at 6 and 12 months post-randomisation, with resource use additionally collected at 3 and 9 months.

DISCUSSION

This protocol outlines a randomised controlled trial to investigate whether modified therapies are cost-effective and improve quality of life for people who repeatedly self-harm. Few interventions are proven to be deliverable in the NHS for this population. This study is strengthened by the involvement of qualified mental health workers experienced in managing risk as therapists.

A pilot randomised controlled trial of acceptance and commitment therapy for medication decision-making and quality of life in women with breast cancer: The ACTION trial

OBJECTIVE

Non-adherence to adjuvant endocrine therapy (AET) in women with breast cancer is common and associated with medication side-effects and distress. We co-designed an Acceptance and Commitment Therapy intervention (ACTION) to enhance medication decision-making and quality of life (QoL). We undertook a pilot trial of ACTION to inform the feasibility of a phase III trial, and to examine intervention acceptability.

METHODS

This was a multi-site, exploratory, two-arm, individually randomised external pilot trial. Women with early breast cancer prescribed AET were randomised (1:1) to receive usual care (UC) or UC + ACTION. The ACTION intervention comprised a remotely delivered one-to-one ACT session followed by three group sessions delivered by clinical psychologists, alongside a website containing ideas for the self-management of side effects.

RESULTS

Of the 480 women screened for eligibility, 260 (54.2%) were approached and 79 (30.4%) randomised. 71 (89.9%) women provided data at 3-month and 70 (88.6%) at 6-month 40 women were randomised to receive UC + ACTION and 32 (80.0%) completed the intervention. Most (75.0%) accessed the website at least once. ACTION was acceptable to participants (Borkovec & Nau Scale: mean = 7.8 [SD = 2.7] out of 10). Signals of effectiveness in favour of the UC + ACTION arm were observed for medication adherence (Adherence Starts with Knowledge questionnaire-12), QoL (work and social adjustment scale), health-related QoL (functional assessment of cancer therapy[FACT] general and FACT-ES-19/23), distress (generalised anxiety disorder -7, patient health questionnaire-9) and psychological flexibility (valuing questionnaire).

CONCLUSIONS

The ACTION intervention was acceptable to patients. There were promising signals for effectiveness on primary and secondary outcomes. A phase III randomised controlled trial is feasible.

Needs, Modes, and Stances: Three Cardinal Questions for Psychotherapy Practice and Training

Background

Advances in motivational science (Dweck, 2017), personality dynamics (Lazarus & Rafaeli, 2023), and process-based psychotherapy (Hofmann & Hayes, 2019) converge into a pragmatic, integrative, and transtheoretical model of practice and training.

Method

The model comprises three elements: a formulation centered on clients' psychological needs which provides guidance regarding the goals and processes most profitable to pursue; a recognition that such pursuit frequently requires contending with a multiplicity of clients' internal self-states (i.e., modes); and an enumeration of pragmatic therapeutic stances likely to help address clients' need-related goals in light of their modes.

Results

We distill these elements into three cardinal questions: What needs does this client have that are not currently met, and what are the most profitable ways of remedying that frustration? What mode or modes does this client manifest - both generally and at this very moment? and What stance should I adopt in response to the client's current mode? We suggest that clinicians should be trained to continually pose these questions and seek to answer them collaboratively with their clients.

Conclusion

This model - illustrated here using schema therapy terms - offers a process-based approach which serves as a theoretically integrative starting point but is general enough to provide an assimilative integration roadmap for therapists anchored in most primary orientations. Integrative or assimilative therapists trained to attend to needs, modes, and stances are likely to be (and be perceived as) particularly responsive, and thus, to enact "common factor" practices known to be conducive to therapeutic alliance and gains.

Acceptance and Commitment Therapy Processes and Mediation: Challenges and How to Address Them

Acceptance and commitment therapy (ACT) emphasizes a focus on theory-driven processes and mediating variables, a laudable approach. The implementation of this approach would be advanced by addressing five challenges, including (a) distinguishing ACT processes in measurement contexts, (b) developing and rigorously validating measures of ACT processes, (c) the wide use of psychometrically weaker ACT process measures and the more limited use of stronger measures in earlier work, (d) the inconsistency of past evidence that ACT processes are sensitive or specific to ACT or mediate ACT outcomes specifically, and (e) improving statistical power and transparency. Drawing on the existing literature, we characterize and provide evidence for each of these challenges. We then offer detailed recommendations for how to address each challenge in ongoing and future work. Given ACT's core focus on theorized processes, improving the measurement and evaluation of these processes would significantly advance the field's understanding of ACT.

Effectiveness of Acceptance and Commitment Therapy (ACT) for the Management of Postsurgical Pain: Study Protocol of a Randomized Controlled Trial (SPINE-ACT Study)

Research on the use of Acceptance and Commitment Therapy (ACT) for patients with degenerative lumbar pathology awaiting surgery are limited. However, there is evidence to suggest that this psychological therapy may be effective in improving pain interference, anxiety, depression, and quality of life. This is the protocol for a randomized controlled trial (RCT) to evaluate the effectiveness of ACT compared to treatment as usual (TAU) for people with degenerative lumbar pathology who are candidates for surgery in the short term. A total of 102 patients with degenerative lumbar spine pathology will be randomly assigned to TAU (control group) or ACT + TAU (intervention group). Participants will be assessed after treatment and at 3-, 6-, and 12-month follow-ups. The primary outcome will be the mean change from baseline on the Brief Pain Inventory (pain interference). Secondary outcomes will include changes in pain intensity, anxiety, depression, pain catastrophizing, fear of movement, quality of life, disability due to low back pain (LBP), pain acceptance, and psychological inflexibility. Linear mixed models will be used to analyze the data. Additionally, effect sizes and number needed to treat (NNT) will be calculated. We posit that ACT may be used to help patients cope with the stress and uncertainty associated with their condition and the surgery itself.

A randomised controlled trial of acceptance and commitment therapy for improving quality of life in people with muscle diseases

Abstract.

BACKGROUND

Chronic muscle diseases (MD) are progressive and cause wasting and weakness in muscles and are associated with reduced quality of life (QoL). The ACTMuS trial examined whether Acceptance and Commitment Therapy (ACT) as an adjunct to usual care improved QoL for such patients as compared to usual care alone.

METHODS

This two-arm, randomised, multicentre, parallel design recruited 155 patients with MD (Hospital and Depression Scale ⩾ 8 for depression or ⩾ 8 for anxiety and Montreal Cognitive Assessment ⩾ 21/30). Participants were randomised, using random block sizes, to one of two groups: standard medical care (SMC) (n = 78) or to ACT in addition to SMC (n = 77), and were followed up to 9 weeks. The primary outcome was QoL, assessed by the Individualised Neuromuscular Quality of Life Questionnaire (INQoL), the average of five subscales, at 9-weeks. Trial registration was NCT02810028.

RESULTS

138 people (89.0%) were followed up at 9-weeks. At all three time points, the adjusted group difference favoured the intervention group and was significant with moderate to large effect sizes. Secondary outcomes (mood, functional impairment, aspects of psychological flexibility) also showed significant differences between groups at week 9.

CONCLUSIONS

ACT in addition to usual care was effective in improving QoL and other psychological and social outcomes in patients with MD. A 6 month follow up will determine the extent to which gains are maintained.

Acceptability, fidelity and trial experience of four intervention components to support medication adherence in women with breast cancer: A process evaluation protocol for a pilot fractional factorial trial

Background

The Refining and Optimising a behavioural intervention to Support Endocrine Therapy Adherence (ROSETA) programme has developed four intervention components aiming to improve medication adherence in women with early-stage breast cancer. These are (a) text messages, (b) information leaflet, (c) Acceptance and Commitment Therapy-based guided self-help (ACT), (d) side-effect management website. Guided by the Multiphase Optimisation Strategy, our pilot trial will use a fractional factorial design to evaluate the feasibility of undertaking a larger optimisation trial. The pilot will include a process evaluation to maximise learning regarding the fidelity and acceptability of the intervention components before proceeding with a larger trial. The trial process evaluation has three aims: to assess the (1) fidelity and (2) acceptability of the intervention components; and (3) to understand participant's trial experience, and barriers and facilitators to recruitment and retention.

Methods

The process evaluation will use multiple methods. Fidelity of the intervention components will be assessed using self-reported questionnaire data, trial data on intervention component adherence, and observations of the ACT sessions. Acceptability of the intervention components and trial experience will be explored using an acceptability questionnaire and interviews with patients and trial therapists. Trial experience will be assessed using a questionnaire and interviews with participants, while barriers and facilitators to recruitment and retention will be assessed using a questionnaire completed by research nurses and participant interviews. The pilot trial opened for recruitment on 20th May 2022 and was open at the time of submission.

Conclusions

This process evaluation will provide information regarding whether the intervention components can be delivered with fidelity within a national healthcare setting and are acceptable to participants. We will also better understand participant experience in a pilot trial with a fractional factorial design, and any barriers and facilitators to recruitment and retention.

Refining and optimising a behavioural intervention to support endocrine therapy adherence (ROSETA) in UK women with breast cancer: protocol for a pilot fractional factorial trial

INTRODUCTION

Women with breast cancer who do not adhere to adjuvant endocrine therapy (AET) have increased risks of mortality and recurrence. There are multiple barriers to AET adherence, including medication side-effects, beliefs about medication, memory and psychological distress. We developed four intervention components, each targeting a different barrier. This pilot trial is part of the preparation phase of the Multiphase Optimisation Strategy, and aims to establish key trial parameters, establish intervention component adherence, establish availability and feasibility of outcome and process data, estimate variability in planned outcome measures and estimate cost of developing and delivering each intervention component.

METHODS AND ANALYSIS

The four intervention components are as follows: short message service text reminders (target: memory); a written information leaflet (target: medication beliefs); a guided self-help Acceptance and Commitment Therapy programme (target: psychological flexibility to reduce distress) and a self-management website (target: side-effect management). To evaluate the feasibility of recruitment, acceptability of the intervention components and the availability of outcome data, we will conduct a multisite, exploratory pilot trial using a 24-1 fractional factorial design, with a nested process evaluation. We will randomise 80 women with early-stage breast cancer who have been prescribed AET to one of eight experimental conditions. This will determine the combination of intervention components they receive, ranging from zero to four, with all conditions receiving usual care. Key outcomes of interest include medication adherence and quality of life. Progression to the optimisation phase will be based on predefined criteria for consent rates, patient adherence to intervention components and availability of medication adherence data.

ETHICS AND DISSEMINATION

The study was reviewed by the Wales Research Authority Research Ethics Committee 3 (21/WA/0322). Written informed consent will be obtained from all patients before randomisation. The results of this trial will be disseminated in a peer-reviewed journal.

An integrated mindfulness meditation and acceptance and commitment therapy intervention for chronic pain: Rationale, design, and methodology of a pilot randomized controlled trial of Acting with Mindfulness for Pain (AMP)

Acceptance and commitment therapy (ACT) is an evidence-based psychosocial intervention for chronic pain; however, in its present form ACT produces modest improvements in function and is no more effective than cognitive behavioral therapy (CBT), the current gold standard. This protocol paper describes the Acting with Mindfulness for Pain (AMP) protocol, which emphasizes and integrates formal mindfulness meditation practice within an ACT-based approach. This paper presents the rationale, design and methodology of an ongoing pilot randomized controlled trial (RCT) comparing AMP to CBT among Veterans with chronic pain (N = 86). Specifically, we argue that formal meditation practice is a necessary treatment component that directly targets key ACT processes which will help facilitate large treatment effects on function (e.g., general activity, social relationships, life enjoyment) among individuals with chronic pain. This study will be the first to consider formal mindfulness meditation practice as a principal treatment ingredient in the context of ACT for chronic pain. The purpose of this trial is to evaluate the feasibility of recruitment and collection of measures, and to examine preliminary treatment effects to determine the appropriateness of a subsequent full-scale RCT. This study will also explore within and between group change on primary and secondary outcomes including pain interference, pain acceptance, trait mindfulness, pain catastrophizing, values-based living, quality of life, practice adherence, and objective measures of physical activity. This study will help delineate the role of formal mindfulness practice within an ACT-based approach for chronic pain and provide preliminary data for a future fully powered RCT.

Exercise combined with Acceptance and Commitment Therapy compared with a standalone supervised exercise programme for adults with chronic pain: a randomised controlled trial

ABSTRACT

A prospective, 2-armed, parallel group randomised controlled trial (RCT) was conducted to compare the effectiveness of Acceptance and Commitment Therapy (ACT) combined with a supervised exercise programme with a supervised exercise programme alone for adults with chronic pain. One hundred seventy-five participants were individually randomised to receive either the combined Exercise and ACT (ExACT) intervention or supervised exercise alone. Those allocated to the ExACT group attended 8 weekly sessions with a psychologist based on the ACT approach, in addition to supervised exercise classes led by a physiotherapist. The control group attended weekly supervised exercise classes but did not take part in an ACT programme. Both groups were followed up postintervention and again after 12 weeks. The primary outcome was pain interference at 12-week follow-up. Estimates of treatment effects at follow-up were based on intention-to-treat analyses, implemented using a linear mixed-effects model. The findings of this RCT showed no difference in the effectiveness of ExACT, compared with a supervised exercise programme alone for the primary outcome pain interference at 12-week follow-up (mean difference -0.18, 95% confidence interval -0.84 to 0.48, P = 0.59, d = 0.11). ExACT group participants reported superior outcomes for pain self-efficacy, pain catastrophising, and committed action, compared with the control group, but there were no differences between the groups for other secondary outcomes or treatment process measures. Higher levels of treatment satisfaction and global impression of change were reported by ExACT group participants. Exercise combined with Acceptance and Commitment Therapy was not superior to a standalone supervised exercise programme for reducing pain interference in adults with chronic pain.

Brief and Telehealth Acceptance and Commitment Therapy (ACT) Interventions for Stress in Inflammatory Bowel Disease (IBD): A Series of Single Case Experimental Design (SCED) Studies

Psychological intervention targeting distress is now considered an integral component of inflammatory bowel disease (IBD) management. However, significant barriers to access exist which necessitate the development of effective, economic, and accessible brief and remote interventions. Acceptance and commitment therapy (ACT) is a therapy with demonstrated acceptability and a growing evidence base for the treatment of distress in IBD populations. The present paper trialled two brief ACT interventions via randomized multiple baseline designs. Study 1 trialled a single-session ACT intervention (delivered face-to-face and lasting approximately two hours) targeting stress and experiential avoidance, respectively. Participants were seven people with an IBD diagnosis who presented with moderate to extremely severe stress (five females, two males; M age = 39.57, SD = 5.74). The findings of study 1 indicate that a single-session ACT intervention represented an insufficient dosage to reduce stress and experiential avoidance. Study 2 investigated a brief telehealth ACT intervention (delivered via a video conferencing platform and lasting approximately four hours) targeting stress and increased psychological flexibility. Participants (N = 12 people with an IBD diagnosis and mild to extremely severe stress) completed baselines lasting from 21 to 66 days before receiving a two-session ACT telehealth intervention supplemented by a workbook and phone consultation. Approximately half of participants experienced reduced stress, increased engagement in valued action, and increased functioning. Despite shortcomings such as missing data and the context of COVID-19, the present findings suggest that brief ACT interventions in this population may be effective and economic, though further research and replications are necessary.

A group resilience training program for people with multiple sclerosis: Study protocol of a multi-centre cluster-randomized controlled trial (multi-READY for MS)

Introduction

REsilience and Activities for every DaY (READY) is an Acceptance and Commitment Therapy-based group resilience-training program that has preliminary empirical support in promoting quality of life and other psychosocial outcomes in people with multiple sclerosis (PwMS). Consistent with the Medical Research Council framework for developing and evaluating complex interventions, we conducted a pilot randomized controlled trial (RCT), followed by a phase III RCT. The present paper describes the phase III RCT protocol.

Methods and analysis

This is a multi-centre cluster RCT comparing READY with a group relaxation program (1:1 ratio) in 240 PwMS from eight centres in Italy (trial registration: isrctn.org Identifier: ISRCTN67194859). Both interventions are composed of 7 weekly sessions plus a booster session five weeks later. Resilience (primary outcome), mood, health-related quality of life, well-being and psychological flexibility will be assessed at baseline, after the booster session, and at three and six month follow-ups. If face-to-face group meetings are interrupted because of COVID-19 related-issues, participants will be invited to complete their intervention via teleconferencing. Relevant COVID-19 information will be collected and the COVID-19 Peritraumatic Distress scale will be administered (ancillary study) at baseline and 3-month follow-up. Analysis will be by intention-to-treat to show superiority of READY over relaxation. Longitudinal changes will be compared between the two arms using repeated-measures, hierarchical generalized linear mixed models.

Conclusion

It is expected that his study will contribute to the body of evidence on the efficacy and effectiveness of READY by comparing it with an active group intervention in frontline MS rehabilitation and clinical settings. Results will be disseminated in peer-reviewed journals and at other relevant conferences.

Acceptance and Commitment Therapy to support medication decision-making and quality of life in women with breast cancer: protocol for a pilot randomised controlled trial

BACKGROUND

Adherence to adjuvant endocrine therapy is affected by medication side-effects and associated distress. Previous interventions focused on educating women to enhance adherence have proved minimally effective. We co-designed an Acceptance and Commitment Therapy (ACT) intervention to enhance medication decision-making and quality of life by targeting a broader range of factors, including side-effect management and psychological flexibility. This study aims to establish key trial parameters, assess the acceptability of the intervention and the extent to which it can be delivered with fidelity, and to demonstrate "proof of principle" regarding its efficacy on primary and process outcomes.

METHODS

The ACTION intervention includes an individual 1:1 ACT session followed by three group sessions involving 8-10 women and two practitioner psychologists. Participants are also provided with access to a website containing evidence-based methods for self-managing side-effects. The ACT sessions were adapted during the COVID-19 pandemic to be remotely delivered via video conferencing software. To evaluate the feasibility and acceptability of this intervention, a multi-site, exploratory, two-arm, individually randomised external pilot trial with a nested qualitative study will be undertaken. Eighty women with early stage breast cancer prescribed adjuvant endocrine therapy will be randomised (1:1) to receive treatment as usual or treatment as usual plus the ACTION intervention. The planned future primary outcome is medication adherence assessed by the ASK-12 measure. Progression to a phase III RCT will be based on criteria related to recruitment and follow-up rates, acceptability to patients, competency and fidelity of delivery, and proof of principle for change in medication adherence.

DISCUSSION

This external pilot trial will be used to ascertain the feasibility of undertaking a future phase III RCT to definitively evaluate an ACT-based intervention to support medication taking behaviour and quality of life in women with early stage breast cancer on adjuvant endocrine therapy.

ACTing towards better living during COVID-19: The effects of Acceptance and Commitment therapy for individuals affected by COVID-19

The widespread effects of COVID-19 have dramatically increased the prevalence of mental health difficulties, meaning it is vital to explore psychotherapy options. Acceptance and Commitment therapy (ACT) helps individuals engage in meaningful activities despite difficult and unchangeable circumstances. Recent literature suggests that psychological flexibility, the underlying process of ACT, may moderate COVID-related distress – making ACT a promising psychotherapy candidate. This study therefore aimed to explore the effects of an ACT-based, guided self-help intervention on wellbeing, psychological flexibility, COVID-related distress, and general psychological distress within the general population. 48 participants (recruited via social media) engaged in a three-week, non-concurrent baseline phase, then received six, weekly, digital modules and weekly webinars to address module queries. 20 participants completed all modules and provided post-intervention feedback via an online qualitative survey. Multilevel modelling analysis found significant improvements in: wellbeing; overall psychological flexibility (including subscales behavioural awareness and valued action); and general psychological distress (including depression, anxiety and stress). No significant changes were found for COVID-related distress. Findings were sustained at one- and two-months follow-up – suggesting lasting change. Qualitative findings provide further insights about the experience of the intervention: participants reported improved wellbeing, still experiencing COVID-related distress, but felt more able to cope with general psychological distress (such as anxiety). No change in COVID-related distress scores may be due to methodological and measurement issues. This study is one of the first to explore ACT as a psychotherapeutic intervention for COVID-related distress and adds to the growing body of literature highlighting psychological flexibility as a key process for mitigating COVID-related distress.

Group-based acceptance and commitment therapy interventions for improving general distress and work-related distress in healthcare professionals: A systematic review and meta-analysis

BACKGROUND

A large proportion of the healthcare workforce reports significant distress and burnout, which can lead to poor patient care. Several psychological interventions, such as Acceptance and Commitment Therapy (ACT), have been applied to improve general distress and work-related distress in healthcare professionals (HCPs). However, the overall efficacy of ACT in this context is unknown. This review and meta-analysis aimed to: 1) test the pooled efficacy of ACT trials for improving general distress and reducing work-related distress in HCPs; 2) evaluate the overall study quality and risk of bias; and 3) investigate potential moderators of intervention effectiveness.

METHOD

Four databases (Ovid MEDLINE, EMBASE, PsycINFO, CINHAL) were searched, with 22 pre-post design and randomised controlled trial (RCTs) studies meeting the inclusion criteria. 10 RCTs studies were included in the meta-analysis.

RESULTS

Two random effects meta-analyses on general distress and work-related distress found that ACT outperformed pooled control conditions with a small effect size for general distress at post-intervention (g = 0.394, CIs [.040; .748]) and for work-related distress (g = 0.301, CIs [.122; .480]) at follow-up. However, ACT was more effective than controls. The number of treatment sessions was a moderator of intervention efficacy for general distress. ACT process measures (psychological flexibility) did not show significantly greater improvements in those who received the intervention.

LIMITATIONS

The methodological quality of studies was poor and needs to be improved.

CONCLUSIONS

Overall, ACT interventions are effective in improving general distress and work-related distress in HCPs. These findings have implications for policymakers, healthcare organisations and clinicians.

Coached, Coordinated, Enhanced Neonatal Transition (CCENT): protocol for a multicentre pragmatic randomised controlled trial of transition-to-home support for parents of high-risk infants

INTRODUCTION

Having an infant admitted to the neonatal intensive care unit (NICU) is associated with increased parental stress, anxiety and depression. Enhanced support for parents may decrease parental stress and improve subsequent parent and child outcomes. The Coached, Coordinated, Enhanced Neonatal Transition (CCENT) programme is a novel bundled intervention of psychosocial support delivered by a nurse navigator that includes Acceptance and Commitment Therapy-based coaching, care coordination and anticipatory education for parents of high-risk infants in the NICU through the first year at home. The primary objective is to evaluate the impact of the intervention on parent stress at 12 months.

METHODS AND ANALYSIS

This is a multicentre pragmatic randomised controlled superiority trial with 1:1 allocation to the CCENT model versus control (standard neonatal follow-up). Parents of high-risk infants (n=236) will be recruited from seven NICUs across three Canadian provinces. Intervention participants are assigned a nurse navigator who will provide the intervention for 12 months. Outcomes are measured at baseline, 6 weeks, 4, 12 and 18 months. The primary outcome measure is the total score of the Parenting Stress Index Fourth Edition Short Form at 12 months. Secondary outcomes include parental mental health, empowerment and health-related quality of life for calculation of quality-adjusted life years (QALYs). A cost-effectiveness analysis will examine the incremental cost of CCENT versus usual care per QALY gained. Qualitative interviews will explore parent and healthcare provider experiences with the intervention.

Systematic Review of Acceptance and Commitment Therapy in Individuals with Neurodevelopmental Disorders, Caregivers, and Staff

The purpose of this review was to quantitatively synthesize studies using acceptance and commitment therapy (ACT) with individuals with neurodevelopmental disorders (NNDs), their parents, and staff members that support them. Thirty studies published in peer-reviewed journals between 2006 and 2020 met inclusion criteria. They were reviewed and coded on variables associated with participants' characteristics, settings, dropouts, design type, ACT procedures and measures, social validity, treatment integrity, and main findings. The What Works Clearinghouse (WWC), the revised Cochrane risk-of-bias tool for randomized trials (RoB2) and the Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) were applied to evaluate the quality of the studies. Results indicated that 20 studies used group designs and 10 studies used single-case designs. Participants with NNDs consisted predominantly of those with autism spectrum disorder, attention deficit hyperactivity disorder, and learning disabilities. Group studies reported process and outcome measures exclusively; whereas, single-case studies also incorporated behavioral/direct measures. Overall, results showed mixed improvements across studies using indirect and direct measures. Lastly, quality assessment for group studies presented moderate or serious risk of bias and two single-case studies did not meet WWC evidence of effectiveness. Directions for future research and practice are discussed.

Acceptance and commitment therapy for young brain tumour survivors: study protocol for an acceptability and feasibility trial

INTRODUCTION

Survivors of childhood brain tumours have the poorest health-related quality of life of all cancer survivors due to the multiple physical and psychological sequelae of brain tumours and their treatment. Remotely delivered acceptance and commitment therapy (ACT) may be a suitable and accessible psychological intervention to support young people who have survived brain tumours. This study aims to assess the feasibility and acceptability of remotely delivered ACT to improve quality of life among these young survivors.

METHODS AND ANALYSIS

This study is a two-arm, parallel group, randomised controlled trial comparing ACT with waitlist control at 12-week follow-up as the primary endpoint. Seventy-two participants will be recruited, who are aged 11-24 and have completed brain tumour treatment. Participants will be randomised to receive 12 weeks of ACT either immediately or after a 12-week wait. The DNA-v model of ACT will be employed, which is a developmentally appropriate model for young people. Feasibility will be assessed using the proportion of those showing interest who consent to the trial and complete the intervention. Acceptability will be assessed using participant evaluations of the intervention, alongside qualitative interviews and treatment diaries analysed thematically. A range of clinical outcome measures will also assess physical and mental health, everyday functioning, quality of life and service usage at 12-week follow-up. The durability of treatment effects will be assessed by further follow-up assessments at 24 weeks, 36 weeks and 48 weeks.

ETHICS AND DISSEMINATION

Ethical approval was given by East Midlands, Nottingham 1 Research Ethics Committee (Reference: 20/EM/0237). Study results will be disseminated in peer-reviewed journals, through public events and relevant third sector organisations.

Protocol for a Phase Two, Parallel Three-Armed Non-inferiority Randomized Controlled Trial of Acceptance and Commitment Therapy (ACT-Adjust) Comparing Face-to-Face and Video Conferencing Delivery to Individuals With Traumatic Brain Injury Experiencing Psychological Distress

Background: People with traumatic brain injury (TBI) face a range of mental health challenges during the adjustment process post-injury, but access to treatment can be difficult, particularly for those who live in regional and remote regions. eHealth provides the potential to improve access to evidence-based psychological therapy for people with a severe TBI. The aim of the current study is to assess the efficacy of a psychological intervention delivered via video consulting to reduce psychological distress in people with TBI. Methods: This paper outlines the protocol for a multi-center, three-arm, parallel, non-inferiority randomized controlled trial (RCT) of an evidence-based manualized psychological intervention, ACT-Adjust. ACT-Adjust provides nine sessions for adults with a moderate to severe TBI experiencing clinical levels of psychological distress. Fifty-six participants referred from Brain Injury Rehabilitation Units across New South Wales (NSW) and the NSW icare scheme will be randomly allocated to three conditions; (1) video consulting (VC), (2) face-to-face (FtF) and, (3) a waitlist control (WL). Discussion: This is the first RCT to evaluate the efficacy of a psychological therapy (ACT-Adjust) delivered via video consulting for individuals with a moderate to severe TBI.

A brief acceptance and commitment intervention for work-related stress and burnout amongst frontline homelessness staff: A single case experimental design series

PURPOSE

Recent intervention research for burnout amongst those working in health and social care contexts has found acceptance and commitment therapy (ACT) interventions to be of use but has provided less clarity on the role of psychological flexibility (a key ACT construct). This study further evaluated the usefulness of ACT for burnout and work-engagement and assessed the role of psychological flexibility in contributing to therapeutic change.

PROCEDURE

A nonconcurrent multiple-baseline across-participants single-case experimental design was used. Four participants were recruited from a homelessness organization in the East Midlands, England. The ACT-intervention was split into three modules to reflect the three aspects of the ACT triflex, and the sequence of delivery was randomized for each participant in order to test the relationship between these aspects.

FINDINGS

Support was found for the ACT intervention reducing exhaustion and increasing work-engagement. Psychological Flexibility increased in all participants and was temporally related to increases in other outcome variables in some instances. Delivery of the intervention focussed on any given aspect of the ACT triflex could increase different domains of psychological flexibility.

IMPLICATIONS

This study adds to the growing body of research in favour of ACT interventions for burnout and adds to the understanding of psychological flexibility as a mediating variable.

Efficacy, cost-utility and physiological effects of Acceptance and Commitment Therapy (ACT) and Behavioural Activation Treatment for Depression (BATD) in patients with chronic low back pain and depression: study protocol of a randomised, controlled trial including mobile-technology-based ecological momentary assessment (IMPACT study)

INTRODUCTION

The IMPACT study focuses on chronic low back pain (CLBP) and depression symptoms, a prevalent and complex problem that represents a challenge for health professionals. Acceptance and Commitment Therapy (ACT) and Brief Behavioural Activation Treatment for Depression (BATD) are effective treatments for patients with persistent pain and depression, respectively. The objectives of this 12 month, multicentre, randomised, controlled trial (RCT) are (i) to examine the efficacy and cost-utility of adding a group-based form of ACT or BATD to treatment-as-usual (TAU) for patients with CLBP and moderate to severe levels of depressive symptoms; (ii) identify pre-post differences in levels of some physiological variables and (iii) analyse the role of polymorphisms in the FKBP5 gene, psychological process measures and physiological variables as mediators or moderators of long-term clinical changes.

METHODS AND ANALYSIS

Participants will be 225 patients with CLBP and moderate to severe depression symptoms recruited at Parc Sanitari Sant Joan de Déu (St. Boi de Llobregat, Spain) and Hospital del Mar (Barcelona, Spain), randomly allocated to one of the three study arms: TAU vs TAU+ACT versus TAU+BATD. A comprehensive assessment to collect clinical variables and costs will be conducted pretreatment, post-treatment and at 12 months follow-up, being pain interference the primary outcome measure. The following physiological variables will be considered at pretreatment and post-treatment assessments in 50% of the sample: immune-inflammatory markers, hair cortisol and cortisone, serum cortisol, corticosteroid-binding globulin and vitamin D. Polymorphisms in the FKBP5 gene (rs3800373, rs9296158, rs1360780, rs9470080 and rs4713916) will be analysed at baseline assessment. Moreover, we will include mobile-technology-based ecological momentary assessment, through the Pain Monitor app, to track ongoing clinical status during ACT and BATD treatments. Linear mixed-effects models using restricted maximum likelihood, and a full economic evaluation applying bootstrapping techniques, acceptability curves and sensitivity analyses will be computed.

ETHICS AND DISSEMINATION

This study has been approved by the Ethics Committee of the Fundació Sant Joan de Déu and Hospital del Mar. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media and various community engagement activities.
