Acceptance and Commitment Therapy plus usual care for improving quality of life in people with motor neuron disease (COMMEND): a multicentre, parallel, randomised controlled trial in the UK.

BACKGROUND: Motor neuron disease is a progressive, fatal neurodegenerative disease for which there is no cure. Acceptance and Commitment Therapy (ACT) is a psychological therapy incorporating acceptance, mindfulness, and behaviour change techniques. We aimed to evaluate the effectiveness of ACT plus usual care, compared with usual care alone, for improving quality of life in people with motor neuron disease. METHODS: We conducted a parallel, multicentre, two-arm randomised controlled trial in 16 UK motor neuron disease care centres or clinics. Eligible participants were aged 18 years or older with a diagnosis of definite or laboratory-supported probable, clinically probable, or possible familial or sporadic amyotrophic lateral sclerosis; progressive muscular atrophy; or primary lateral sclerosis; which met the World Federation of Neurology's El Escorial diagnostic criteria. Participants were randomly assigned (1:1) to receive up to eight sessions of ACT adapted for people with motor neuron disease plus usual care or usual care alone by a web-based system, stratified by site. Participants were followed up at 6 months and 9 months post-randomisation. Outcome assessors and trial statisticians were masked to treatment allocation. The primary outcome was quality of life using the McGill Quality of Life Questionnaire-Revised (MQOL-R) at 6 months post-randomisation. Primary analyses were multi-level modelling and modified intention to treat among participants with available data. This trial was pre-registered with the ISRCTN Registry (ISRCTN12655391). FINDINGS: Between Sept 18, 2019, and Aug 31, 2022, 435 people with motor neuron disease were approached for the study, of whom 206 (47%) were assessed for eligibility, and 191 were recruited. 97 (51%) participants were randomly assigned to ACT plus usual care and 94 (49%) were assigned to usual care alone. 80 (42%) of 191 participants were female and 111 (58%) were male, and the mean age was 63·1 years (SD 11·0). 155 (81%) participants had primary outcome data at 6 months post-randomisation. After controlling for baseline scores, age, sex, and therapist clustering, ACT plus usual care was superior to usual care alone for quality of life at 6 months (adjusted mean difference on the MQOL-R of 0·66 [95% CI 0·22-1·10]; d=0·46 [0·16-0·77]; p=0·0031). Moderate effect sizes were clinically meaningful. 75 adverse events were reported, 38 of which were serious, but no adverse events were deemed to be associated with the intervention. INTERPRETATION: ACT plus usual care is clinically effective for maintaining or improving quality of life in people with motor neuron disease. As further evidence emerges confirming these findings, health-care providers should consider how access to ACT, adapted for the specific needs of people with motor neuron disease, could be provided within motor neuron disease clinical services.

Cost-effectiveness of acceptance and commitment therapy for people living with motor neuron disease, and their health-related quality of life.

BACKGROUND: Given the degenerative nature of the condition, people living with motor neuron disease (MND) experience high levels of psychological distress. The purpose of this research was to investigate the cost-effectiveness of acceptance and commitment therapy (ACT), adapted for the specific needs of this population, for improving quality of life. METHODS: A trial-based cost-utility analysis over a 9-month period was conducted comparing ACT plus usual care (n = 97) versus usual care alone (n = 94) from the perspective of the National Health Service. In the primary analysis, quality-adjusted life years (QALYs) were computed using health utilities generated from the EQ-5D-5L questionnaire. Sensitivity analyses and subgroup analyses were also carried out. RESULTS: Difference in costs was statistically significant between the two arms, driven mainly by the intervention costs. Effects measured by EQ-5D-5L were not statistically significantly different between the two arms. The incremental cost-effectiveness was above the £20,000 to £30,000 per QALY gained threshold used in the UK. However, the difference in effects was statistically significant when measured by the McGill Quality of Life-Revised (MQOL-R) questionnaire. The intervention was cost-effective in a subgroup experiencing medium deterioration in motor neuron symptoms. CONCLUSIONS: Despite the intervention being cost-ineffective in the primary analysis, the significant difference in the effects measured by MQOL-R, the low costs of the intervention, the results in the subgroup analysis, and the fact that ACT was shown to improve the quality of life for people living with MND, suggest that ACT could be incorporated into MND clinical services.

Study protocol for a three-arm randomized controlled trial investigating the effectiveness, cost-utility, and physiological effects of a fully self-guided digital Acceptance and Commitment Therapy for Spanish patients with fibromyalgia.

Objective: Fibromyalgia (FM) is a prevalent pain syndrome with significant healthcare and societal costs. The aim of the SMART-FM-SP study is to determine the effectiveness, cost-utility, and physiological effects in patients with FM of a digital intervention (STANZA®) currently marketed in the United States, which delivers smartphone-based, fully self-guided Acceptance and Commitment Therapy (Digital ACT) for treating FM-related symptoms. Methods: A single-site, parallel-group, superiority, randomized controlled trial (RCT) will be conducted, including a total of 360 adults diagnosed with FM. Individuals will be randomly allocated (1:1:1) to treatment as usual (TAU), to TAU plus 12 weeks of treatment with Digital ACT, or to TAU plus 12 weeks of treatment with digital symptom tracking (i.e. FibroST). Participants will be assessed at baseline, post-treatment, and 6-month follow-up. An intention-to-treat analysis using linear mixed models will be computed to analyze the effects of Digital ACT on functional impairment (primary outcome), as measured by the Fibromyalgia Impact Questionnaire Revised at 6 months from the inception of the treatment. Secondary outcomes include impression of change, symptoms of distress, pain catastrophising, quality of life, cost-utility, and selected biomarkers (cortisol and cortisone, immune-inflammatory markers, and FKBP5 gene polymorphisms). The role of ACT-related processes of change will be tested with path analyses. Conclusions: This study is the first RCT that tests Digital ACT for Spanish patients with FM. Results will be important not only for patients and clinicians, but also for policy makers by examining the cost-utility of the app in a public healthcare context.

Guided internet-based acceptance and commitment therapy for provoked vestibulodynia: A randomized controlled trial.

BACKGROUND: Provoked vestibulodynia (PVD) causes suffering in many women's lives due to its impact on relationships, sexual functioning and functioning in other key domains. OBJECTIVE: Here, we report a randomized controlled trial conducted to examine whether Acceptance and Commitment Therapy (ACT) with a focus on values-based exposure, delivered online, benefits women with PVD. METHODS: Participants (n = 88) were randomized to either guided online ACT for 10 weeks or a wait-list control group. Outcomes were assessed at baseline, post treatment and 1 year later. Analyses were based on intention to treat using linear mixed models. RESULTS: There were significant group differences on the primary outcomes, Female Sexual Index and Female Sexual Distress Scale, in favour of online ACT with moderate effect sizes. Differences were also found on several secondary outcomes and therapeutic process measures, all in favour of ACT. No differences were found at post-treatment for depression or anxiety. At the 1-year follow-up, results were maintained and a difference between baseline and follow-up was also found for depression. CONCLUSION/SIGNIFICANCE: In summary, a relatively brief, guided, online version of ACT appears to produce benefits for women with PVD and related impacts on daily functioning. 50% to 60% of the women who participated in the treatment reliably improved in sexual functioning and distress.

Access to psychological treatment for chronic cancer-related pain in Sweden.

OBJECTIVES: Cancer-related pain (CRP) is among the most frequent collateral effects of cancer, with chronic CRP, lasting at least 3 months, affecting >40% of cancer survivors. Evidence-based treatments, including pain-focused cognitive behavioral therapy (CBT), are available, but it appears that cancer patients/survivors are often poorly informed about CRP or the potential benefits of CBT for such pain. This study examined current experience of Swedish cancer patients/survivors in relation to CRP. METHODS: Participants (N = 276; 83% female; mean age = 55.5 years, SD = 11.9) were recruited to an online survey via cancer websites in Sweden, and they provided information about their history of chronic CRP and whether they received information about or treatment for CRP from a healthcare professional. RESULTS: Participants had a history of breast (36%), gynecological (12%), lung (10%), colon (8%), and other forms of cancer (36%). A majority (74%) reported a history of chronic CRP and being prescribed analgesic medications (70%). Less than half (47%) received information from their healthcare provider about the risk of CRP and only 13% with chronic CRP received psychological treatment, and of these, only 33% received CBT. Among those receiving psychological treatment for chronic CRP, satisfaction rates were moderate, reported as an average of 6 on a 0-10 scale (standard deviation 2.6). CONCLUSIONS: Greater efforts are needed to raise awareness among cancer patients/survivors and healthcare providers about the risk of CRP and evidence-based interventions, including CBT, the first-line intervention for chronic pain. These efforts will need to be matched with increases in treatment capacity, particularly pain-focused CBT.

An investigation of the associations between stigma, self-compassion, and pain outcomes during treatment based on Acceptance and Commitment Therapy for chronic pain.

Introduction: Stigma adversely affects people with chronic pain. The qualities within self-compassion may be particularly useful for buffering the impact of stigma on people with pain. In the context of an Acceptance and Commitment Therapy-based (ACT) treatment for chronic pain, this study investigated the association between changes in stigma and self-compassion and pain outcomes, and the potential moderating role of self-compassion on the association between stigma and pain outcomes. Materials and methods: Five-hundred and nineteen patients completed standardized self-report questionnaires of stigma, self-compassion, psychological flexibility, pain intensity and interference, work and social adjustment, and depression symptoms at the start of an interdisciplinary ACT-based treatment for chronic pain. The same measures were completed at post-treatment (n = 431). Results: The results indicated that key pain outcomes and self-compassion significantly improved during treatment, but stigma did not. Changes in stigma and self-compassion were significantly negatively correlated and changes in these variables were associated with improvements in treatment outcomes. There were significant main effects of stigma and self-compassion for many of the pre- and post-treatment regression models when psychological flexibility was not controlled for, but self-compassion did not moderate the association between stigma and pain outcomes. Stigma remained significant when psychological flexibility variables were controlled for, while self-compassion did not. Discussion: The findings add to our conceptual understanding of the inter-relationships between stigma, self-compassion, and psychological flexibility and can contribute to treatment advancements to optimally target these variables.

Ultra-brief acceptance & commitment therapy for inpatients with psychosis - a single-case experimental design investigating processes of change.

People with primary psychosis are among the most seen in inpatient psychiatry. Treatment guidelines recommend both pharmacological and psychological treatments. However, psychological treatments are not routinely offered in many settings. There is also a lack of research on psychological treatments for this vulnerable population in the inpatient setting. The first aim of the current study was to examine treatment effects of a brief form of Acceptance and Commitment Therapy on outcomes valued by the treatment recipients. The second aim was to explore hypothetical processes of change in relation to outcomes over time. Three people with primary psychosis were treated for two to four sessions. A replicated single-case experimental design with multiple baselines across subjects (Clinical Trials registration number ID NCT04704973) was employed to examine treatment effects. The Personal Questionnaire (PQ) was used as primary outcome, symptom believability and preoccupation as proposed processes of change. Data were analyzed using visual inspection, calculation of Tau-U values, and cross-lagged correlation. All participants improved significantly on PQ and the symptom preoccupation measure. Two improved significantly on the symptom believability measure. Cross-lagged correlation analyses showed no clear mediation. Change in proposed processes of change and primary outcome predominantly happened concomitantly, although patterns of results reflected individual differences.

Economic Evaluation of Videoconference Group Acceptance and Commitment Therapy and Behavioral Activation Therapy for Depression Versus Usual Care Among Adults With Chronic Low Back Pain Plus Comorbid Depressive Symptoms.

Chronic pain and depression are frequently comorbid conditions associated with significant health care and social costs. This study examined the cost-utility and cost-effectiveness of videoconference-based group forms of Acceptance and Commitment Therapy (ACT) and Behavioral Activation Therapy for Depression (BATD), as a complement to treatment-as-usual (TAU), for patients with chronic low back pain (CLBP) plus depressive symptoms, compared to TAU alone. A trial-based economic evaluation (n = 234) was conducted from a governmental and health care perspective with a time horizon of 12 months. Primary outcomes were the Brief Pain Inventory-Interference Scale (BPI-IS) and Quality Adjusted Life Year. Compared to TAU, ACT achieved a significant reduction in total costs (d = .47), and BATD achieved significant reductions in indirect (d = .61) and total costs (d = .63). Significant improvements in BPI-IS (d = .73 and d = .66, respectively) and Quality Adjusted Life Year scores (d = .46 and d = .28, respectively) were found in ACT and BATD compared to TAU. No significant differences in costs and outcomes were found between ACT and BATD. In the intention-to-treat analyses, from the governmental and health care perspective, no significant differences in cost reduction and incremental effects were identified in the comparison between ACT, BATD, and TAU. However, in the complete case analysis, significant incremental effects of ACT (∆BPI-IS = -1.57 and -1.39, respectively) and BATD (∆BPI-IS = -1.08 and -1.04, respectively) compared with TAU were observed. In the per-protocol analysis, only the significant incremental effects of ACT (∆BPI-IS = -1.68 and -1.43, respectively) compared to TAU were detected. In conclusion, ACT and BATD might be efficient options in the management of CLBP plus comorbid depression symptoms as compared to usual care. However, no clear difference was found in the comparison between the 2 active therapies regarding cost-effectiveness or cost-utility. PERSPECTIVE: The economic evaluation of psychological therapies for the management of complex conditions can be used in decision-making and resource allocation. This study provides evidence that ACT and BATD are more effective and involve a greater reduction in costs than usual care in the management of CLBP plus comorbid depressive symptoms. TRIAL NUMBER: NCT04140838.

Psychological Treatment of Exhaustion Due to Persistent Non-Traumatic Stress: A Scoping Review.

BACKGROUND: Exhaustion due to persistent non-traumatic stress (ENTS) is a significant health problem with substantial personal, social, and economic impact. While there are increasing studies of ENTS, there is no international agreement on how it should be diagnosed and treated. This scoping review aimed to map definitions, diagnoses, treatments, outcome measures, and outcomes in psychological treatment studies of ENTS. A further aim was to assess the quality of the treatments and map what change processes are described within ENTS interventions. METHODS: A PRISMA-guided scoping review of psychological treatment studies delivered in a clinical setting for ENTS was conducted using the databases of PubMed, PsycINFO, and CINAHL. RESULTS: Of the 60 studies included, the majority (87%) stemmed from Europe. The most recurrent term for ENTS was burnout, and the diagnosis most often utilized was exhaustion disorder. Several treatments were reported, the most frequent being cognitive behavioral therapy (CBT) (68%). Statistically significant outcomes relevant to ENTS were reported in 65% (n = 39) of the studies, with effect sizes between 0.13 and 1.80. In addition, 28% of the treatments were rated as high quality. The most frequent change processes described were dysfunctional sleep, avoidance, behavioral activation, irrational thoughts and beliefs, worry, perceived competence/positive management, psychological flexibility, and recuperation. CONCLUSIONS: While several treatments based on CBT show promising results for ENTS, there do not seem to be any uniformly established methods, theoretical models, or change processes. Instead of adopting a monocausal, syndromal, and potentially bio-reductionist perspective on ENTS, a process-based approach to treatment is encouraged.

Self-guided digital acceptance and commitment therapy for fibromyalgia management: results of a randomized, active-controlled, phase II pilot clinical trial.

Although empirically validated for fibromyalgia (FM), cognitive and behavioral therapies, including Acceptance and Commitment Therapy (ACT), are inaccessible to many patients. A self-guided, smartphone-based ACT program would significantly improve accessibility. The SMART-FM study assessed the feasibility of conducting a predominantly virtual clinical trial in an FM population in addition to evaluating preliminary evidence for the safety and efficacy of a digital ACT program for FM (FM-ACT). Sixty-seven patients with FM were randomized to 12 weeks of FM-ACT (n = 39) or digital symptom tracking (FM-ST; n = 28). The study population was 98.5% female, with an average age of 53 years and an average baseline FM symptom severity score of 8 out of 11. Endpoints included the Fibromyalgia Impact Questionnaire-Revised (FIQ-R) and the Patient Global Impression of Change (PGIC). The between-arm effect size for the change from baseline to Week 12 in FIQ-R total scores was d = 0.44 (least-squares mean difference, - 5.7; SE, 3.16; 95% CI, - 11.9 to 0.6; P = .074). At Week 12, 73.0% of FM-ACT participants reported improvement on the PGIC versus 22.2% of FM-ST participants (P < .001). FM-ACT demonstrated improved outcomes compared to FM-ST, with high engagement and low attrition in both arms. Retrospectively registered at ClinicalTrials.gov (NCT05005351) on August 13, 2021.

Psychometric evaluation of the Pain Vigilance and Awareness Questionnaire (PVAQ) in fibromyalgia: Confirmatory factor analysis and the development of a Swedish 8-item version.

BACKGROUND: Excessive attention to pain, or hypervigilance, is associated with negative outcomes in chronic pain conditions such as fibromyalgia. The Pain Vigilance and Awareness Questionnaire (PVAQ) is a self-report questionnaire to measure attention to pain. This study aimed to evaluate the psychometric properties of a Swedish version of the PVAQ. METHODS: Psychometric evaluation on cross-sectional data derived from a clinical trial for fibromyalgia (N = 274). We evaluated item characteristics, factor structure in a confirmatory factor analytic framework, internal consistency, and construct validity in terms of correlations with other clinical variables. RESULTS: Though confirmatory factor analysis did not result in a satisfactory solution for the full 16-item scale, acceptable two-factor solutions could be based on either nine or eight items (the PVAQ-9 and PVAQ-8). Internal consistency for both the PVAQ-9 and PVAQ-8 were good to excellent, and associations with pain catastrophizing, anxiety, depression, disability, and overall fibromyalgia impact were largely supportive of construct validity. An unexpected result was that, contrary to previous findings, no version of the PVAQ correlated consistently with pain intensity. CONCLUSIONS: The Swedish PVAQ-9 and PVAQ-8 appear to have acceptable psychometric properties when administered online to individuals with fibromyalgia. The PVAQ-8 may be preferable due to being shorter and including an equal number of items per factor. Replication is warranted. SIGNIFICANCE: This study evaluated the psychometric properties of a Swedish translation of the PVAQ in individuals with fibromyalgia. No convincing factor structure was found for the 16-item version. We could, however, confirm the factor structure of an established 9-item version (the PVAQ-9), and recommend further use of a new 8-item version (the PVAQ-8). In summary, the PVAQ exhibited more convincing psychometric properties when the number of items was roughly cut in half.

Psychological Flexibility, Chronic Pain, and Health.

Psychological flexibility is a model of human performance and well-being. It essentially entails an approach to life circumstances that includes openness, awareness, and engagement. It has roots in behavior analysis, and it is linked to a philosophy of science called functional contextualism and to a specific therapy approach called Acceptance and Commitment Therapy. One of the earliest and most developed research areas in which this model and therapy have been applied is chronic pain. This review describes psychological flexibility and its facets in more detail, sets them in a context of relevant psychological models, and examines related assessment and treatment methods. It also examines evidence, current challenges, and future directions. It is proposed that psychological flexibility, or an expanded model very much like it, could provide a basis for integrating current research and treatment approaches in chronic pain and health generally. This, in turn, could produce improved treatments for people with chronic pain and other conditions.

Associations between psychological flexibility and daily functioning in endometriosis-related pain.

OBJECTIVES: Processes of psychological flexibility (PF) are positively associated with health and wellbeing in several chronic pain disorders. However, these processes have not been investigated in endometriosis, a chronic pain disorder affecting 5-10 % of women worldwide. This study is a preliminary investigation of the associations between PF or psychological inflexibility (PI) and daily functioning in people with a primary diagnosis of endometriosis. METHODS: This study is based on a secondary analysis of survey data from Swedish-speaking adult participants with chronic pain recruited online. The current study included only those reporting a diagnosis of endometriosis and significant long-term pain. All participants completed the Multidimensional Psychological Flexibility Inventory (MPFI), a measure of PF and PI, as well as other measures of PF, and measures of pain and daily functioning. Correlation and multiple regression analyses were performed to examine relations of PF and PI with measures of pain and daily functioning. RESULTS: In general, PF facet scores from the MPFI did not correlate with pain interference but did correlate with depression, with the exception of acceptance. The overall facets of PI appeared to perform better as correlates and in regression. Established measures of PF performed in correlation and regression analyses generally as has been observed in other chronic pain populations, with significant positive associations. CONCLUSIONS: In this preliminary analysis of PF and PI in participants with endometriosis-related pain, these processes appear relevant, especially in understanding depression, but results varied along with the measures used. Specifically, when employing the MPFI, the PI facets emerged as stronger correlates. The findings underscore the potential benefit of incorporating assessments of PF and PI as process variables in endometriosis-research, but also that careful consideration should be given when selecting instruments.

COVID-19 and mental health in the UK: Depression, anxiety and insomnia and their associations with persistent physical symptoms and risk and vulnerability factors.

OBJECTIVES: Mental health problems and persistent COVID-19 symptoms were prevalent in the context of COVID-19. However, despite the long-observed association between physical symptoms and mental health problems, such association has not been adequately examined in the context of COVID-19. Our understanding of wider patterns of risk and vulnerability factors for mental health also remains limited. This study investigated the associations between general mental health, and persistent physical symptoms, and additional risk and vulnerability factors in the context of COVID-19. METHODS: Two hundred fourteen adults, living in the UK, recruited via social media, completed the online survey and were included in the analyses. Correlation and regression analyses were conducted to examine the associations of persistent physical symptoms and risk and vulnerability factors with measures of general mental health including depressive symptoms, anxiety and insomnia. RESULTS: 78.5% of the participants reported between 1 and 26 persistent symptoms, and about 28%-92% of them associated these symptoms with COVID-19 infection. Persistent physical symptoms were uniquely associated with all measures of mental health, ß = .19-.32. Mental health history and worries were the most prominent risk factors, |ß| = .12-.43. CONCLUSIONS: People who experience more persistent physical symptoms post-COVID-19 have poorer mental health. It may be important to consider and discuss the recovery from COVID-19 beyond a negative COVID-19 test. Multidisciplinary interventions that address the complex impact of COVID-19 for people with long COVID are needed.

Mediators during a Multimodal intervention for stress-induced exhaustion disorder.

Our understanding of the underlying psychological processes of development, maintenance, and treatments for stress-induced exhaustion disorder (ED) remains limited. Therefore, the current study aimed to explore whether sleep concerns, pathological worry, perfectionistic concerns, and psychological flexibility mediate change in exhaustion symptoms during a Multimodal intervention for ED based on Cognitive behavioral therapy principles. Participants (N = 913) were assessed at three time points, and mediation was explored using a two-criteria analytical model with linear mixed-effects models (criterion one) and random intercepts cross-lagged panel modeling (criterion 2). Criterion one for mediation was successfully met, as the findings indicated significant associations between time in treatment, with all suggested mediators, and exhaustion symptoms (significant ab-products). However, criterion two was not satisfied as changes in the mediators did not precede changes in exhaustion symptoms. Therefore, mediation could not be established. Instead, changes in the suggested mediators appeared to result from changes in exhaustion symptoms. Consequently, sleep concerns, pathological worry, perfectionistic concerns, and psychological flexibility appear to improve in conjunction with exhaustion symptoms during treatment, where improvement in exhaustion is indicated as the main driving factor, based on this exploratory analysis. The implications of these findings are contextualized within a broader framework of process-based therapy.

The Pain Anxiety Symptom Scale: Initial Development and Evaluation of 4 and 8 Item Short Forms.

Elevated levels of anxiety in relation to chronic pain have been consistently associated with greater distress and disability. Thus, accurate measurement of pain-related anxiety is an important requirement in modern pain services. The Pain Anxiety Symptom Scale (PASS) was introduced over 30 years ago, with a shortened 20-item version introduced 10 years later. Both versions of the PASS were derived using Principal Components Analysis, an established method of measure development with roots in classical test theory. Item Response Theory (IRT) is a complementary approach to measure development that can reduce the number of items needed and maximize item utility with minimal loss of statistical and clinical information. The present study used IRT to shorten the 20-item PASS (PASS-20) in a large sample of people with chronic pain (N = 2,669). Two shortened versions were evaluated, 1 composed of the single best-performing item from each of its 4 subscales (PASS-4) and the other with the 2 best-performing items from each subscale (PASS-8). Several supplementary analyses were performed, including comparative item convergence evaluations based on sample characteristics (ie, female or male sex; clinical or online sample), factor invariance testing, and criterion validity evaluation of the 4, 8, and 20-item versions of the PASS in hierarchical regression models predicting pain-related distress and interference. Overall, both shortened PASS versions performed adequately across these supplemental tests, although the PASS-4 had more consistent item convergence between samples, stronger evidence for factor invariance, and accounted for 83% of the variance accounted for by the PASS-20% and 92% of the variance accounted for by the PASS-8 in criterion variables. Consequently, the PASS-4 is recommended for use in situations where a briefer evaluation of pain-related anxiety is appropriate. PERSPECTIVE: The Pain Anxiety Symptom Scale (PASS) is an established measure of pain-related fear. This study derived 4 and 8-item versions of the PASS using IRT. Both versions showed strong psychometric properties, stability of factor structure, and relation to important aspects of pain-related functioning.

Participant experiences of guided self-help Acceptance and Commitment Therapy for improving quality of life in muscle disease: a nested qualitative study within the ACTMus randomized controlled trial.

Introduction: In adults, muscle disease (MD) is typically a chronic long-term condition that can lead to a reduced quality of life (QoL). Previous research suggests that a psychological intervention, in particular Acceptance and Commitment Therapy (ACT), may help improve QoL for individuals living with chronic conditions such as MD. Methods: This nested qualitative study was incorporated within a randomized controlled trial which evaluated a guided self-help ACT intervention for people living with MD to explore their experiences of the intervention. Semi-structured interviews (n = 20) were conducted with those who had received ACT. Data were analyzed via thematic analysis. Results: There were four overarching themes. (1) Views on whether therapy sessions would help with a medical condition: participants' expectations regarding ACT varied. Some participants were skeptical about mindfulness. (2) I was able to look at things in a different way: participants described increased meaningful activity, greater awareness of thoughts and emotions and acceptance or adaptation to mobility problems. Some described improvement in the quality of relationships and a sense of feeling free. (3) Treating the body and the mind together: following the intervention participants noted that a holistic approach to healthcare is beneficial. (4) Intervention delivery: The remote delivery was generally seen as helpful for practical reasons and allowed participants to speak openly. Participants voiced a need for follow-up sessions. Discussion: Overall, the intervention was experienced as acceptable. Suggested improvements included de-emphasizing the role of mindfulness and adding follow-up sessions.

Experiences of patients with chronic low back pain plus comorbid depressive symptoms in a videoconference group acceptance and commitment therapy or behavioral activation treatment for depression: a qualitative study.

PURPOSE: To explore the experiences of patients with chronic low back pain (CLBP) plus comorbid depressive symptoms who received a remote synchronous videoconference group form of Acceptance and Commitment Therapy (ACT) or Behavioral Activation Treatment for Depression (BATD). METHODS: A qualitative study (IMPACT-Q) was nested within a randomized controlled trial (RCT) designed to assess the efficacy and the cost-utility/cost-effectiveness of two therapies in the management of CLBP and depression. Fifty-five patients with CLBP plus depression were selected from the RCT. Twelve focus group sessions, each approximately 60-90 min long, were audio-recorded, transcribed verbatim, and analyzed by six coders through a thematic analysis (deductive and inductive) based on a descriptive phenomenological approach. RESULTS: Patients perceived behavioral, affective, and cognitive improvements after completing group sessions. Overall, psychotherapy was perceived as a safe and non-judgmental place to express emotions and feel understood. The main barriers reported were lack of human contact and loss of social interaction. In contrast, ease of access, flexibility in the ability to connect from anywhere, avoidance of the need to travel, and savings in time and money were key facilitators to increase attendance and adherence to therapy. CONCLUSION: This study provided support for the acceptability of videoconference-delivered ACT or BATD in patients with CLBP plus comorbid depressive symptoms.

Overall, patients reported behavioral, affective, and cognitive improvements after Acceptance and Commitment Therapy and Behavioral Activation Treatment for Depression group sessions.Acceptance and Commitment Therapy and Behavioral Activation Treatment for Depression delivered via videoconference platform were perceived as a facilitator for therapy attendance rather than a barrier.The findings indicate that group therapy on videoconferencing is perceived favorably as an alternative for managing patients with chronic pain and comorbid depression.Technical and social aspects of implementing videoconferencing therapies should be improved, as well as guidelines for adequate support for patients and therapists should also be provided.

An online acceptance, commitment, and self-compassion based treatment to decrease psychological distress in people with type 2 diabetes: A feasibility randomised-controlled trial.

Background and purpose: This study explored the feasibility and acceptability of conducting a larger trial of a self-guided, online self-compassion and acceptance and commitment therapy (ACT) focused treatment among people with type 2 diabetes (T2D) to decrease psychological distress. Materials and methods: This study was a two-arm, parallel, feasibility randomised controlled trial with nested qualitative methods. UK adults with T2D were randomly (1:1) allocated to a five-week online self-compassion and ACT treatment or waitlist control. Information regarding recruitment, trial retention, and treatment completion was collected, and post-treatment semi-structured interviews were conducted to assess feasibility and acceptability. Self-report measures of psychological distress (depression, anxiety, diabetes distress) and potential treatment processes (self-compassion and psychological flexibility) were completed as secondary feasibility outcomes. Results: Fifty-five (60.44 %) out of 91 people who accessed the study link were eligible to participate. Of these, 33 eligible participants (60 %) were randomly assigned to treatment (n = 19) or control arms (waitlist; n = 14). While treatment completion was 47.37 %, trial retention rates were 39.39 % (5-week follow-up) and 21.2 % (9-week follow-up). Secondary feasibility outcomes of treatment effect estimates are difficult to interpret in light of low treatment completion and trial retention rates. Conclusion: A larger trial of the self-guided, online self-compassion treatment to decrease psychological distress in people with T2D may be beneficial, but it has limited feasibility in its current form. Further efforts are needed to improve treatment acceptability of online self-compassion and ACT focused treatment and trial procedures.

A feasibility trial of online Acceptance and Commitment Therapy for women with provoked vestibulodynia.

OBJECTIVES: Acceptance and Commitment Therapy (ACT) is an established treatment for chronic pain. However, it is a form of treatment that have not yet been applied much in the treatment of persistent vulvar pain disorders. This study examines the feasibility and preliminary effects of online ACT for patients with provoked vestibulodynia. METHODS: Women diagnosed with provoked vestibulodynia were assigned randomly either to online ACT or to a waitlist control group. Feasibility was assessed in terms of recruitment potential, treatment credibility, completions rates, retention in trial, and data quality. Participants completed measures of pain with sexual activity, sexual functioning, emotional and relational adjustment, and potential treatment processes before and after treatment. RESULTS: Of the 111 women who were invited to participate in the study, 44 were included (39.6 % recruitment rate). Thirty seven participants (84.1 %) completed the pre-treatment assessment. Participants who received online ACT rated treatment credibility positively, and completed on average 4.31 (SD=1.60) of the six treatment modules. Of participants, 34 provided post treatment data, giving a trial retention rate of 77 %. Effects of online ACT, as compared to waitlist, were large for pain acceptance and quality of life, medium for anxiety and pain catastrophizing, and small for sexual satisfaction, pain with sexual activity, and relationship adjustment. CONCLUSIONS: With some adjustments to recruitment procedures, a full scale randomized controlled trial of online ACT for provoked vestibulodynia appears feasible.
