Effectiveness of acceptance and commitment therapy for mental illness in cancer patients: A systematic review and meta-analysis of randomised controlled trials

Effectiveness of Acceptance and Commitment Therapy on Reducing Depression and Anxiety in Older Adults: A Systematic Review and Meta-Analysis

OBJECTIVE

To assess the effectiveness of acceptance and commitment therapy (ACT) in reducing depressive and anxiety symptoms in older adults.

DESIGN

A systematic review and meta-analysis.

METHODS

Nine databases were searched for publications up to 2 April 2024, using combinations of search terms related to depression, anxiety, ACT, older adults and randomised controlled trials (RCTs). Two researchers were selected according to inclusion and exclusion criteria, data extraction and methodological quality evaluation, and Stata 16.0 software was used for meta-analysis.

RESULTS

Seven articles were included in a systematic review and six were in a meta-analysis. The results indicated that, compared to the control group, ACT had a small but significant effect in reducing depressive symptom (SMD = -0.22, 95% CI, -0.38 to -0.06, p < 0.001; 576 older adults; low-quality evidence), while it showed a small, non-significant effect on reducing anxiety symptoms (SMD = -0.29, 95% CI, -0.73 to 0.15, p = 0.194; 576 older adults; very low-quality evidence). Subgroup analysis based on the different control conditions may have some enlightenment on the sources of heterogeneity.

CONCLUSION

ACT can be an important component of future psychotherapy for older adults, as it may alleviate depressive symptoms. However, high-quality studies with large samples, multiple centres and long follow-up durations should be performed to further reliably assess the treatment effects of depressive symptoms and explore potential benefits for anxiety symptoms.

Acceptability of acceptance and commitment therapy for medication-decision-making and quality of life in women with breast cancer: A qualitative process evaluation

OBJECTIVES

Adjuvant endocrine therapy (AET) reduces breast cancer recurrence, but side effects and distress impact adherence. We co-designed an Acceptance and Commitment Therapy (ACT) intervention to support medication decision-making and quality of life in women prescribed AET (ACTION). In a qualitative process evaluation nested in the pilot trial, we aimed to elicit participant experiences of receipt and therapists experience of delivery of ACTION to enhance our understanding of acceptability.

DESIGN

Remote semi-structured interviews were conducted with women with breast cancer who received ACTION (n = 20) and trial therapists (n = 3).

METHODS

Interviews were guided by the Theoretical Framework of Acceptability (TFA). Rapid Assessment Procedure (RAP) sheets were completed after each interview to map responses onto TFA constructs, and sections of interviews were selectively transcribed. Individual RAP sheets were collated to identify key findings.

RESULTS

ACTION was generally liked, in particular, the group format (affective attitude). Participants and therapists felt ACTION was low effort, but therapists acknowledged the burden associated with trial procedures (burden). Participants generally felt able to engage with ACTION, and therapists felt they were able to deliver it (self-efficacy). The perceived effectiveness of ACTION on well-being was good, but was mixed for impact on treatment adherence (perceived effectiveness). Participants and therapists understood the aims of ACTION (coherence), and ACTION generally aligned with therapists' values (ethicality). Therapists questioned who would be most appropriate to deliver ACTION (opportunity costs).

CONCLUSION

ACTION was acceptable to women with breast cancer and trial therapists. Rapid qualitative analysis can facilitate efficient process evaluations in time- and resource-limited contexts.

Adults diagnosed with gynecologic cancer and their relationship with their body: A study on the supportive role of yoga using interpretative phenomenological analysis

The purpose of this qualitative study was to explore the thoughts, feelings, attitudes, and perceptions of adults diagnosed with gynecologic cancer on their body, and the role of yoga in shaping these aspects. A phenomenological research design was used. Fifteen women (Mage=50.1 ± 13.5 years, range=28-66) who practice yoga at least once/week completed a sociodemographic survey online, two semi-structured interviews, and a 30-day journal online. Quantitative data were analysed using descriptive statistics. Qualitative data were analysed using interpretative phenomenological analysis. Participants' responses and the authors' interpretations were summarized into four main superordinate themes: (1) internal monologue of the changed body, (2) balancing act between acceptance and improvement, (3) value of taking time to prioritize oneself by practicing yoga, and (4) transformative catalysts of expectation and mindset on body-related self-perceptions after yoga. Body functionality and appearance, and their sexual health were often deeply interconnected, and impacted participants' self-perceptions and behaviours. Yoga was a vehicle for growth and acceptance; however, participants' expectations and mindsets before and during yoga could lead to negative self-perceptions after yoga. The findings underscore the importance of integrating yoga - a holistic practice - into survivorship care programs, while emphasizing the need to address expectations and attitudes that could hinder positive outcomes.

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.

A qualitative feasibility and acceptability study of an acceptance and commitment-based bibliotherapy intervention for people with cancer

Self-directed bibliotherapy interventions can be effective means of psychological support for individuals with cancer, yet mixed findings as to the efficacy of these interventions indicate the need for further research. We investigated the experience of individuals with cancer after using a new self-help book, based on Acceptance and Commitment Therapy (ACT). Ten participants with cancer (nine females and one male, 40-89 years old) were given access to a bibliotherapy self-help ACT-based book and participated in post-intervention semi-structured interviews. Five themes were generated from reflexive thematic analysis: (1) The value of bibliotherapy (2) Timing is important (3) Resonating with cancer experiences (4) Tools of the book (5) ACT in action. The book was found to be acceptable (self-directed, accessible, understandable content, good responsiveness to exercises) and feasible (easy to use, ACT-consistent). Although not explicitly evaluated, participants' reports indicated defusion, present moment awareness, and consideration of values, as the ACT processes that contributed to adjustment, via helping them to regain control over their lives and become more present within the moment. Findings also indicate that the intervention may be best accessed following completion of initial medical treatment.

Effects of different psychosocial interventions on death anxiety in patients: a network meta-analysis of randomized controlled trials

Objective

This research intended to assess and compare influence of psychosocial interventions in death anxiety in patients, providing evidence-based guidance for both patients and healthcare providers.

Design

The present study exclusively gathered randomized controlled trials by comprehensively searching across multiple databases, comprising of PubMed, Embase, Cochrane Library, Web of Science, and Scopus. The methodological quality of the enrolled studies involved in the analysis was assessed using the Cochrane bias risk assessment tool, and data analysis was performed utilizing appropriate software.

Results

This research, encompassing 15 randomized controlled trials with a cumulative sample size of 926 patients, spanned from the earliest possible date to December 2023. The findings of network meta-analysis unveiled that the Rational-Emotive Hospice Care Therapy significantly reduced death anxiety among patients (Sequentially Updated Cumulative Ranking Analysis: 100%).

Conclusion

Working after cancer: psychological flexibility and the quality of working life

PURPOSE

Our purpose was to examine the associations between the pillars of psychological flexibility (valued action, behavioural awareness, openness to experience) and aspects of quality of working life after a cancer. We examined how the pillars of psychological flexibility mediated the relationships between quality of working life and anxiety, depression, and overall life satisfaction. Examining psychological flexibility allows interventions to be targeted for cancer survivors and account for unique, individual needs.

METHODS

In this cross-sectional study, 230 cancer survivors who were currently employed completed a questionnaire package that included demographic information and measures of physical health problems, satisfaction with life, quality of working life in cancer survivors, psychological flexibility, anxiety, and depression.

RESULTS

The mediational analyses illustrated how specific pillars of psychological flexibility mediated the relationships between quality of working life and anxiety, depression, and overall satisfaction with life. Overall, psychological flexibility mediated the relationships between physical health and health-related work problems, quality of working life, and satisfaction with life. Further, the valued action pillar of psychological flexibility fully mediated the relationship between quality of working life and reported symptoms of depression and anxiety.

CONCLUSIONS

Higher psychological flexibility was related to higher satisfaction with working life. Physical and psychological challenges during employment may be improved through interventions that improve psychological flexibility. Active engagement with activities aligned with personal values is related to more positive outcomes.

IMPLICATIONS FOR CANCER SURVIVORS

The value of examining the pillars of psychological flexibility is that interventions can be targeted for this population, considering this population's unique needs.

Acceptance and commitment therapy reduces psychological distress in patients with cancer: a systematic review and meta-analysis of randomized controlled trials

Objective

This study aimed to systematically review and meta-analyze the clinical efficacy of acceptance and commitment therapy (ACT) in patients with cancer and psychological distress.

Methods

Randomized controlled trials (RCTs) from seven English electronic databases were systematically investigated from inception to 3 October 2023. A total of 16 RCTs from 6 countries with 711 participants were included in this study. Estimated pooled effect sizes (ESs) were calculated via inverse-variance random-effects or fixed-effects (I2 ≤ 50%) model and presented by standardized mean difference (SMD). Subgroup analyses were performed to reduce confounding factors and heterogeneity, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to evaluate the quality of the pooled ESs.

Results

The pooled ESs revealed that statistically significant improvements in anxiety [postintervention SMD = -0.41 (95% confidence interval (CI), -0.71, -0.11); p = 0.008; I2 = 65%; follow-up SMD = -0.37 (95% CI, -0.66, -0.08); p = 0.01; I2 = 29%], depression [postintervention SMD = -0.45 (95% CI, -0.63, -0.27); p < 0.001; I2 = 49%; follow-up SMD = -0.52 (95% CI, -0.77, -0.28); p < 0.001; I2 = 0%], and psychological flexibility [postintervention SMD = -0.81 (95% CI, -1.50, -0.11); p = 0.02; I2 = 84%; follow-up SMD = -0.71 (95% CI, -1.12, -0.31); p = 0.0006; I2 = 38%] in ACT-treated participants were observed compared to patients treated with control conditions. However, other outcomes, such as physical symptom alleviation, were not significantly associated.

Conclusion

The findings of this systematic review and meta-analysis suggest that ACT is associated with improvements in anxiety, depression, and psychological flexibility in patients with cancer.

Effectiveness of acceptance and commitment therapy on psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer: A meta-analysis of randomized controlled trials

BACKGROUND

Current studies have revealed that acceptance and commitment therapy (ACT) can alleviate the adverse effects of cancer; however, its effectiveness on the psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer remains unclear.

AIMS

The aims of this study were to identify the effectiveness of ACT on psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer, and to explore moderators.

METHODS

PubMed, Embase, Web of Science, CENTRAL, PsycINFO, CINAHL, CNKI, VIP, and Wanfang electronic databases were searched from inception to September 29, 2022. The Cochrane Collaboration's risk-of-bias assessment tool II and the Grading of Recommendations Assessment, Development, and Evaluation approach were used to evaluate evidence certainty. The data were analyzed using R Studio. The study protocol was registered with PROSPERO (CRD42022361185).

RESULTS

The study included 19 relevant studies (1643 patients) published between 2012 and 2022. The pooled results showed that ACT significantly improved psychological flexibility (mean difference [MD] = -4.22, 95% CI [-7.86, -0.58], p = .02) and quality of life (Hedges' g = 0.94, 95% CI [0.59, 1.29], Z = 5.31, p < .01) but did not significantly improve fatigue (Hedges' g = -0.03, 95% CI [-0.24, 0.18], p = .75) or sleep disturbance (Hedges' g = -0.26, 95% CI [-0.82, 0.30], p = .37) in patients with cancer. Additional analyses revealed a 3-month sustainable effect on psychological flexibility (MD = -4.36, 95% CI [-8.67, -0.05], p < .05), and moderation analysis showed that intervention duration (β = -1.39, p < .01) and age (β = 0.15, p = .04) moderated the effects of ACT on psychological flexibility and sleep disturbance, respectively.

LINKING EVIDENCE TO ACTION

Acceptance and commitment therapy demonstrates effectiveness for psychological flexibility and quality of life of patients with cancer, but there is a lack of evidence regarding its effects on fatigue and sleep disturbance. In clinical practice, ACT should be designed in more detail and rounded to achieve better results.

Changes of Symptoms of Anxiety, Depression, and Fatigue in Cancer Patients 3 Months after a Video-Based Intervention

During the COVID-19 pandemic, social distancing restricted psycho-oncological care. Therefore, this secondary analysis examines the changes in anxiety, fear of progression, fatigue, and depression in cancer patients after a video-based eHealth intervention. We used a prospective observational design with 155 cancer patients with mixed tumor entities. Data were assessed before and after the intervention and at a three-month follow-up using self-reported questionnaires (GAD-7, FOP-Q-SF, PHQ-8, and EORTC QLQ-FA12). The eight videos included psychoeducation, Acceptance and Commitment Therapy elements, and yoga and qigong exercises. The results showed that three months after finishing the video-based intervention, participants showed significantly reduced fear of progression (d = -0.23), depression (d = -0.27), and fatigue (d = -0.24) compared to the baseline. However, there was no change in anxiety (d = -0.09). Findings indicated marginal improvements in mental distress when using video-based intervention for cancer patients for up to three months, but long-term effectiveness must be confirmed using a controlled design.

Cancer, now what? A cross-sectional study examining physical symptoms, subjective well-being, and psychological flexibility

Background: The impact of cancer extends beyond treatment and evaluating the adverse psychological effects in survivors is important. We examined: (1) the relationship between diagnosis, relapse, and subjective well-being using a short and a holistic measure of well-being, including comparisons between our sample and established norms; (2) if reported physical symptoms were related to components of subjective well-being; and (3) if increased psychological flexibility predicted overall subjective well-being. Methods: In total, 316 survivors completed online questionnaires to assess cancer, physical health (Edmonton Symptom Assessment Scale-R; ESAS-R), subjective well-being (Comprehensive Inventory of Thriving; CIT; Satisfaction with Life Scale; SWLS) and psychological flexibility (Comprehensive Assessment of Acceptance and Commitment Therapy). Results: Relative to ESAS-R cut-points (Oldenmenger et al., 2013), participants reported only moderate levels of tiredness and slightly elevated drowsiness, depression, and anxiety; participants reported more problems with psychological health. SWLS scores were lower than published norms (M = 18.23, SD = 8.23) and a relapse was associated with the lowest SWLS scores (M = 16.95, SD = 7.72). There were differences in thriving between participants and age-matched norms (Su et al., 2014). Participants reported lower community involvement, respect, engagement with activities, skill mastery, sense of accomplishment, self-worth, self-efficacy, autonomy, purpose, optimism, subjective well-being, and positive emotions coupled with higher loneliness and negative emotions. In regression analysis, two components of psychological flexibility, Openness to Experience, t = 2.50, p < 0.13, β = -0.18, and Valued Action, t = 7.08, p < 0.001, β = -0.47, predicted 28.8% of the variability in total CIT scores, beyond the effects of demographic and disease characteristics and reported physical symptoms. Conclusion: Cancer is an isolating experience, with the adverse psychological effects that impact subjective well-being continuing after the cessation of physical symptoms. Specific components of psychological flexibility may explain some variability in thriving beyond disease characteristics and may inform psychological intervention after diagnosis.

Relations of perceived injustice to psycho-spiritual outcomes in advanced lung and prostate cancer: Examining the role of acceptance and meaning making

OBJECTIVE

Many advanced cancer patients struggle with anxiety, depressive symptoms, and anger toward God and illness-related stressors. Patients may perceive their illness as an injustice (i.e., appraise their illness as unfair, severe, and irreparable or blame others for their illness), which may be a risk factor for poor psychological and spiritual outcomes. This study examined relations between cancer-related perceived injustice and psycho-spiritual outcomes as well as potential mediators of these relationships.

METHODS

Advanced lung (n = 102) and prostate (n = 99) cancer patients completed a one-time survey. Using path analyses, we examined a parallel mediation model including the direct effects of perceived injustice on psycho-spiritual outcomes (i.e., anxiety, depressive symptoms, anger about cancer, anger towards God) and the indirect effects of perceived injustice on psycho-spiritual outcomes through two parallel mediators: meaning making and acceptance of cancer. We then explored whether these relations differed by cancer type.

RESULTS

Path analyses indicated that perceived injustice was directly and indirectly-through acceptance of cancer but not meaning making-associated with psycho-spiritual outcomes. Results did not differ between lung and prostate cancer patients.

CONCLUSIONS

Advanced cancer patients with greater perceived injustice are at higher risk for poor psycho-spiritual outcomes. Acceptance of cancer, but not meaning making, explained relationships between cancer-related perceived injustice and psycho-spiritual outcomes. Findings support testing acceptance-based interventions to address perceived injustice in advanced cancer patients.

Mapping psychosocial interventions in familial colorectal cancer: a rapid systematic review

Background

Approximately 5% of colorectal cancer (CRC) cases are part of a well-defined inherited genetic syndrome and up to approximately 30% of these cases have a clinically defined familial basis. Psychosocial interventions in familial colorectal cancer address aspects mainly focused on affective, cognitive and behavioural outcomes. The present review aims to systematically map out the available psychosocial interventions for individuals with a family history of CRC and describe the current state of the research.

Methods

An extensive electronic search was conducted to investigate the literature published until June 2020. Inclusion criteria consisted of quantitative studies published in English that explored the impact of psychosocial interventions for familial CRC, clearly defined the psychosocial intervention offered and included participants with a family history of CRC.

Results

The analysis included 52 articles. Genetic counselling, educational interventions, psychological interventions and multimodal interventions were identified across the studies. In terms of diagnoses, Lynch Syndrome, Familial Adenomatous Polyposis, Familial Colorectal Cancer were the main conditions included in the studies. Affective, cognitive, behavioural aspects and quality of life emerged as the most frequently explored outcomes. The studies included individuals with both personal and familial history of CRC or family history alone.

Conclusions

Our rapid review provides an overview of the literature exploring the impact of psychosocial interventions for familial CRC. The psychosocial interventions identified had an overwhelmingly positive impact across all types of outcomes measured. Genetic counselling appeared to be most beneficial, and this is expected as it is purposively designed to address genetic conditions. Further quantitative analysis of primary empirical research is needed to determine the efficacy and effectiveness of psychosocial interventions as well as the mechanisms through which they exert their effect.
