Processes in acceptance and commitment therapy and the rehabilitation of chronic fatigue

Acceptance and commitment therapy (ACT) has never been tested for patients with chronic fatigue. We aimed to test if a 3.5‐week ACT rehabilitation program for patients with chronic fatigue improved quality of life (QoL), fatigue, and psychological flexibility. Further, to test if improvements in QoL and fatigue were associated with improvement in psychological flexibility, and if psychological flexibility explained variance above and beyond maladaptive cognitions typically targeted in CBT for fatigue. Patients (n = 140) who had been on sick leave > 8 weeks due to chronic fatigue received a 3.5‐week non‐controlled inpatient rehabilitation program based on ACT. A physician and a psychologist examined the patients, assessing medication use and SCID‐I diagnoses. Patients completed questionnaires about somatic complaints, psychological complaints, and maladaptive cognitions before and after treatment. At post‐treatment, patients reported improved QoL (p < 0.001; g = 1.07) and less fatigue (p < 0.001; g = 1.08), but not increased psychological flexibility (p = 0.6). Changes in psychological flexibility was associated with improved QoL, but not fatigue, in hierarchical regression analyses. When adjusting for other cognitions, changes in fear‐avoidance cognitions and all‐or‐nothing thoughts, but not psychological flexibility, were associated with improved QoL and fatigue. The ACT‐based treatment improved QoL and reduced fatigue for patients with chronic fatigue with large effect sizes. Improvement was associated with a reduction in fear‐avoidance cognitions and all‐or‐nothing thoughts, but not psychological flexibility.     

A preliminary investigation of acceptance and commitment therapy as a treatment for marijuana dependence in adults

In this investigation, 3 adults who met criteria for marijuana dependence were treated using an abbreviated version of acceptance and commitment therapy (ACT). The treatment was delivered in eight weekly 90-min individual sessions. The effects of the intervention were assessed using a nonconcurrent multiple baseline across participants design. Self-reported marijuana use, confirmed through oral swabs, reached zero levels for all participants at posttreatment. At a 3-month follow-up, 1 participant was still abstinent and the other 2 were using but at a lower average level of consumption compared to baseline. Depression, anxiety, withdrawal symptoms, and general levels of experiential avoidance generally improved. This preliminary test suggests that additional development and testing of ACT for marijuana use are warranted.     

Acceptance and commitment therapy versus tinnitus retraining therapy in the treatment of tinnitus: a randomised controlled trial

The study compared the effects of Acceptance and Commitment Therapy (ACT) with Tinnitus Retraining Therapy (TRT) on tinnitus impact in a randomised controlled trial. Sixty-four normal hearing subjects with tinnitus were randomised to one of the active treatments or a wait-list control (WLC). The ACT treatment consisted of 10 weekly 60 min sessions. The TRT treatment consisted of one 150 min session, one 30 min follow-up and continued daily use of wearable sound generators for a recommended period of at least 8 h/day for 18 months. Assessments were made at baseline, 10 weeks, 6 months and 18 months. At 10 weeks, results showed a superior effect of ACT in comparison with the WLC regarding tinnitus impact (Cohen’s d = 1.04), problems with sleep and anxiety. The results were mediated by tinnitus acceptance. A comparison between the active treatments, including all assessment points, revealed significant differences in favour of ACT regarding tinnitus impact (Cohen’s d = 0.75) and problems with sleep. At 6 months, reliable improvement on the main outcome measure was found for 54.5% in the ACT condition and 20% in the TRT condition. The results suggest that ACT can reduce tinnitus distress and impact in a group of normal hearing tinnitus patients.     

A controlled evaluation of acceptance and commitment therapy plus habit reversal for trichotillomania

This randomized trial compared a combined Acceptance and Commitment Therapy/Habit Reversal Training (ACT/HRT) to a waitlist control in the treatment of adults with trichotillomania (TTM). Twenty-five participants (12 treatment and 13 waitlist) completed the trial. Results demonstrated a significant reduction in hair pulling severity, impairment ratings, and hairs pulled, along with significant reductions in experiential avoidance and both anxiety and depressive symptoms in the ACT/HRT group compared to the waitlist control. Reductions generally were maintained at a 3-month follow-up. Decreases in experiential avoidance and greater treatment compliance were significantly correlated with reductions in TTM severity, implying that targeting experiential avoidance may be useful in the treatment of TTM. Other implications and suggestions for future research are noted.     

Riding the waves: A functional‐cognitive perspective on the relations among behaviour therapy,cognitive behaviour therapy and acceptance and commitment therapy

Different types of therapy explain psychopathology and the effects of psychotherapy differently. Different explanations are, however, not necessarily mutually exclusive. Based on the idea that functional and cognitive explanations are situated at different levels, we argue that functional therapies such as traditional Behaviour Therapy (BT) and Acceptance and Commitment Therapy (ACT) are not necessarily incompatible with Cognitive Behaviour Therapy (CBT). Whether a functional and a cognitive therapy actually align depends on whether they highlight the same type of environmental causes. This functional‐cognitive perspective reveals various differences and communalities among BT, CBT and ACT.     

Processes of change in psychological flexibility in an interdisciplinary group-based treatment for chronic pain based on Acceptance and Commitment Therapy

There are now numerous studies of Acceptance and Commitment Therapy (ACT) for chronic pain. These studies provide growing support for the efficacy and effectiveness of ACT in this context as well as for the role of ACT-specific therapeutic processes, particularly those underlying psychological flexibility. The purpose of the present study was to continue to build on this work with a broader focus on these processes, including acceptance of pain, general psychological acceptance, mindfulness, and values-based action. Participants included 168 patients who completed an ACT-based treatment for chronic pain and a three-month follow-up. Following treatment and at follow-up, participants reported significantly reduced levels of depression, pain-related anxiety, physical and psychosocial disability, medical visits, and pain intensity in comparison to the start of treatment. They also showed significant increases in each of the processes of psychological flexibility. Most uncontrolled effect sizes were medium or large at the follow-up. In correlation analyses changes in the four processes measures generally were significantly related to changes in the measures of depression, anxiety, and disability. In regression analyses the combined processes were related to changes in outcomes above and beyond change in pain intensity. Although in some ways preliminary, these results specifically support the unique role of general psychological acceptance in relation to improvements achieved by treatment participants. The current study clarifies potential processes of change in treatment for chronic pain, particularly those aiming to enhance psychological flexibility.     

Cognitive behavioral therapy and acceptance and commitment therapy for insomnia: Exploring the potential benefit of psychological flexibility and self-compassion combined with behavioral strategies

Chronic insomnia is a prevalent sleep disorder with serious consequences on wellbeing and health that largely extend into daily functioning. Cognitive-Behavioral Therapy for Insomnia (CBT-I), an efficacious intervention for insomnia with solid empirical support, is the recommended first-line treatment. Given the complexity of factors and mechanisms involved in its aetiology and maintenance, advances in treatment protocols and modules are important. We will review the current knowledge on insomnia and examine how advancements in behavioral sleep medicine and third-wave therapies may apply to treatment. Specifically, we will outline how a treatment protocol based on Acceptance and Commitment Therapy (ACT), adapted to include insomnia-specific behavioral strategies and with an explicit focus on self-compassion, could be a potentially effective treatment. We believe that broadening treatment focus to target hyperarousal, metacognitions, dysfunctional though control strategies and provide self-compassion training may benefit treatment outcomes, increase sleep quality, reduce daytime symptoms, and improve quality of life.     

Acceptance and values-based action in chronic pain: a three-year follow-up analysis of treatment effectiveness and process

Recent developments in CBT emphasize the promotion of psychological flexibility to improve daily functioning for people with a wide range of health conditions. In particular, one of these approaches, Acceptance and Commitment Therapy (ACT), has been studied for treatment of chronic pain. While trials have provided good support for treatment effectiveness through follow-ups of as long as seven months, the longer-term impact is not known. The present study of 108 participants with chronic pain examined outcomes three years after treatment completion and included analyses of two key treatment processes, acceptance of pain and values-based action. Overall, results indicated significant improvements in emotional and physical functioning relative to the start of treatment, as well as good maintenance of treatment gains relative to an earlier follow-up assessment. Effect size statistics were generally medium or large. At the three-year follow-up, 64.8% of patients had reliably improved in at least one key domain. Improvements in acceptance of pain and values-based action were associated with improvements in outcome measures. A “treatment responder” analysis, using variables collected at pre-treatment and shorter term follow-up, failed to identify any salient predictors of response. This study adds to the growing literature supporting the effectiveness of ACT for chronic pain and yields evidence for both statistical and clinical significance of improvements over a three-year period.     

A randomised worksite comparison of acceptance and commitment therapy and stress inoculation training

In this comparative intervention study, 107 working individuals with above average levels of distress were randomly assigned to one of three conditions: acceptance and commitment therapy (ACT; n = 37); stress inoculation training (SIT; n = 37); or a waitlist control group (n = 33). The interventions were delivered to small groups in the workplace via two half-day training sessions. ACT and SIT were found to be equally effective in reducing psychological distress across a three month assessment period. Mediation analysis indicated that the beneficial impact of ACT on mental health resulted from an increase in psychological flexibility rather than from a change in dysfunctional cognitive content. Contrary to hypothesis, a reduction in dysfunctional cognitions did not mediate change in the SIT condition. Results suggest that the worksite may offer a useful, yet underutilised, arena for testing cognitive-behavioural theories of change.     

Acute treatment of inpatients with psychotic symptoms using Acceptance and Commitment Therapy: pilot results

Cognitive behavior therapy (CBT) has been demonstrated in a number of randomized controlled trials to be efficacious as an adjunctive treatment for psychotic disorders. Emerging evidence suggests the usefulness of CBT interventions that incorporate acceptance/mindfulness-based approaches for this population. The current study extended previous research by Bach and Hayes (2002. The use of Acceptance and Commitment Therapy to prevent the rehospitalization of psychotic patients: A randomized controlled trial. Journal of Consulting and Clinical Psychology, 70, 1129-1139) using Acceptance and Commitment Therapy (ACT) in the treatment of psychosis. Psychiatric inpatients with psychotic symptoms were randomly assigned to enhanced treatment as usual (ETAU) or ETAU plus individual sessions of ACT. At discharge from the hospital, results suggested short-term advantages in the ACT group in affective symptoms, overall improvement, social impairment, and distress associated with hallucinations. In addition, more participants in the ACT condition reached clinically significant symptom improvement at discharge. Although 4-month rehospitalization rates were lower in the ACT group, these differences did not reach statistical significance. Decreases in the believability of hallucinations during treatment were observed only in the ACT condition, and change in believability was strongly associated with change in distress after controlling for change in the frequency of hallucinations. Results are interpreted as largely consistent with the findings of Bach and Hayes and warrant further investigations with larger samples.     

Acceptance and commitment therapy: model, processes and outcomes

The present article presents and reviews the model of psychopathology and treatment underlying Acceptance and Commitment Therapy (ACT). ACT is unusual in that it is linked to a comprehensive active basic research program on the nature of human language and cognition (Relational Frame Theory), echoing back to an earlier era of behavior therapy in which clinical treatments were consciously based on basic behavioral principles. The evidence from correlational, component, process of change, and outcome comparisons relevant to the model are broadly supportive, but the literature is not mature and many questions have not yet been examined. What evidence is available suggests that ACT works through different processes than active treatment comparisons, including traditional Cognitive-Behavior Therapy (CBT). There are not enough well-controlled studies to conclude that ACT is generally more effective than other active treatments across the range of problems examined, but so far the data are promising.     

The effects of brief cognitive-behaviour therapy for pathological skin picking: A randomized comparison to wait-list control

Thirty-four college students suffering from pathological skin picking were randomly assigned to a four-session cognitive-behavioural treatment (n = 17) or a waiting-list condition (n = 17). Severity of skin picking, psycho-social impact of skin picking, strength of skin-picking-related dysfunctional cognitions, and severity of skin injury were measured at pre-, post-, and two-months follow-up assessment. Participants in the treatment condition showed a significantly larger reduction on all measured variables in comparison to the waiting-list condition. The obtained effect sizes for the outcome measures were large, ranging from .90 to 1.89. Treatment effects were maintained at follow-up. In conclusion, cognitive-behavioural therapy, even in brief form, constitutes an adequate treatment option for pathological skin-picking behaviour.     

Comparing the role of psychological flexibility and traditional pain management coping strategies in chronic pain treatment outcomes

Psychologically-based interventions for chronic pain traditionally include a mix of methods, including physical conditioning, training in relaxation or attention control, strategies to decrease irrational or dysfunctional thinking patterns, and activity management training. Recent developments suggest additional methods to promote acceptance, mindfulness, values-based action, and cognitive defusion (a cognitive process entailing change in the influences exerted by thoughts without necessarily changing their form or frequency). Collectively, these processes entail what is referred to as psychological flexibility. This study examined how changes in traditionally conceived methods of coping compare to changes in psychological flexibility in relation to improvements in functioning over the course of an interdisciplinary treatment program. Participants were 114 chronic pain sufferers. Results indicated that changes in the traditionally conceived methods were essentially unrelated to treatment improvements, while changes in psychological flexibility were consistently and significantly related to these improvements. We suggest that psychological flexibility appears highly relevant to the study of chronic pain and to future treatment developments. The utility of more traditionally conceived pain management strategies, on the other hand, may require a reappraisal.

In this study, habit reversal was evaluated as a treatment for skin picking in typically developing adult male siblings using a nonconcurrent multiple baseline across participants design. Results showed socially valid decreases in reported picking as a result of treatment.     

Efficacy of an early intervention based on acceptance and commitment therapy for adults with depressive symptomatology: Evaluation in a randomized controlled trial

Objective

The current study examined the efficacy of an early intervention based on acceptance and commitment therapy (ACT) for depressive symptomatology. The ACT intervention is aimed at increasing the acceptance of negative thoughts and emotions and living a mindful and value-based life.

Method

Adults with mild to moderate depressive symptomatology were randomly assigned to the ACT intervention (n = 49) or to a waiting list (n = 44). The mean age of the participants was 49 years. The majority of the participants was female and of Dutch origin. All the participants completed measures before and after the intervention, as well as three months later at follow-up to assess depression (CES-D), anxiety (HADS-A), fatigue (CIS), alcohol use and acceptance (AAQ-II).

Results

The ACT intervention led to statistically significant reduction in depressive symptomatology (Cohen’s d = .60). These reductions were maintained at the three-month follow-up. Also significant reductions in anxiety and fatigue were observed. Moreover, mediational analysis showed that the improvement of acceptance during the intervention mediated the effects of the intervention on depressive symptomatology at follow-up.

Conclusion

These findings suggest that an early intervention based on ACT, aimed at increasing acceptance, is effective in reducing depressive symptomatology.     

Impact of acceptance and commitment therapy versus education on stigma toward people with psychological disorders

Acceptance and commitment therapy (ACT) has previously been shown to alter stigmatizing attitudes and to be relatively useful for psychologically inflexible participants. The present study is the first to bring those two findings together by comparing ACT to an education intervention for reducing stigma toward people with psychological disorders, and examining whether results differ for psychologically inflexible versus flexible individuals. A sample of college students (N =95) was randomly assigned to a 2(1)2h ACT or educational workshop. Measures were taken before and after the workshop and at a 1-month follow-up. ACT reduced mental health stigma significantly regardless of participants' pre-treatment levels of psychological flexibility, but education reduced stigma only among participants who were relatively flexible and non-avoidant to begin with. Acceptance could be an important avenue of exploration for stigma researchers.     

Acceptance-based treatment for persons with complex, long standing chronic pain: a preliminary analysis of treatment outcome in comparison to a waiting phase

The concept of acceptance is receiving increased attention as an alternate approach to the suffering that is often associated with persistent and disabling pain. This approach differs from established treatments in that it does not principally focus on reducing pain, but on reducing the distressing and disabling influences of pain as they concern important areas in patients' lives. The present analyses represent a preliminary evaluation of an acceptance-based approach to chronic pain within an interdisciplinary treatment program. One hundred and eight patients with complex chronic pain conditions completed treatment and provided data for the current study. Treatment was conducted in a 3- or 4-week residential or hospital-based format. It included a number of exposure-based, experiential, and other behavior change methods focused on increasing (a) engagement in daily activity regardless of pain and (b) willingness to have pain present without responding to it. Significant improvements in emotional, social, and physical functioning, and healthcare use were demonstrated following treatment. The majority of improvements continued at 3-months post-treatment. Improvements in most outcomes during treatment were correlated with increases in acceptance, supporting the proposed process of treatment.     

The Use of a Child-Based Acceptance and Commitment Therapy Curriculum to Increase Attention

Acceptance and Commitment Therapy (ACT) is a treatment that integrates mindfulness and acceptance training with behavior change processes. One of the core processes in ACT is contact with the present moment which involves shifting attention to what is happening here and now, contacting both internal and external stimuli. An experimental and control group were used to determine the impact ACT had on attention. ACT participants (M?=?5.4, SD?=?9.8) showed fewer inaccuracies on the CPT-X task compared to the control group (M?=?19.75, SD?=?16.1) at posttest F(1, 38)?=?11.49, p?=?.02, ηp²?=?.232. Results of the current study demonstrate participation in the use of an ACT curriculum for children to help increase attention outcomes.     

Training in and implementation of Acceptance and Commitment Therapy for depression in the Veterans Health Administration: Therapist and patient outcomes

ObjectiveThe U.S. Department of Veterans Affairs has implemented a national dissemination and training initiative to promote the availability of Acceptance and Commitment Therapy for depression (ACT-D). This paper reports on therapist and patient outcomes associated with competency-based training in and implementation of ACT-D.MethodTherapist and patient outcomes were assessed on eleven cohorts of therapists (n = 391) and their patients (n = 745).ResultsThree-hundred thirty four therapists successfully completed all requirements of the Training Program. Ninety-six percent of therapists achieved competency by the end of training, compared to 21% at the outset of training. Mixed effects model analysis indicated therapists' overall ACT-D competency scores increased from 76 to 112 (conditional SD = 6.6), p < 0.001. Moreover, training was associated with significantly increased therapist self-efficacy and positive attitudes toward ACT-D. Therapeutic alliance increased significantly over the course of therapy. Mixed effects model analysis revealed that mean BDI-II scores decreased from 30 at baseline assessment to 19 (conditional SD = 5.6) at final assessment, t(367) = ?20.3, p < 0.001. Quality of life scores also increased.ConclusionsTraining in and implementation of ACT-D in the treatment of Veterans is associated with significant increases in therapist competency and robust improvements in patient outcomes.
