Analyzing Change Processes Resulting from a Smartphone Maintenance Intervention Based on Acceptance and Commitment Therapy for Women with Chronic Widespread Pain

Psychological therapies delivered remotely for the management of chronic pain (excluding headache) in adults

BACKGROUND

Chronic pain (pain lasting three months or more) is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Common types (excluding headache) include back pain, fibromyalgia, and neuropathic pain. Access to traditional face-to-face therapies can be restricted by healthcare resources, geography, and cost. Remote technology-based delivery of psychological therapies has the potential to overcome treatment barriers. However, their therapeutic effectiveness compared to traditional delivery methods requires further investigation.

OBJECTIVES

To determine the benefits and harms of remotely-delivered psychological therapies compared to active control, waiting list, or treatment as usual for the management of chronic pain in adults.

SEARCH METHODS

We searched for randomised controlled trials (RCTs) in CENTRAL, MEDLINE, Embase, and PsycINFO to 29 June 2022. We also searched clinical trials registers and reference lists. We conducted a citation search of included trials to identify any further eligible trials.

SELECTION CRITERIA

We included RCTs in adults (≥ 18 years old) with chronic pain. Interventions included psychological therapies with recognisable psychotherapeutic content or based on psychological theory. Trials had to have delivered therapy remote from the therapist (e.g. Internet, smartphone application) and involve no more than 30% contact time with a clinician. Comparators included treatment as usual (including waiting-list controls) and active controls (e.g. education).

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures.

MAIN RESULTS

We included 32 trials (4924 participants) in the analyses. Twenty-five studies delivered cognitive behavioural therapy (CBT) to participants, and seven delivered acceptance and commitment therapy (ACT). Participants had back pain, musculoskeletal pain, opioid-treated chronic pain, mixed chronic pain, hip or knee osteoarthritis, spinal cord injury, fibromyalgia, provoked vestibulodynia, or rheumatoid arthritis. We assessed 25 studies as having an unclear or high risk of bias for selective reporting. However, across studies overall, risk of bias was generally low. We downgraded evidence certainty for primary outcomes for inconsistency, imprecision, and study limitations. Certainty of evidence ranged from moderate to very low. Adverse events were inadequately reported or recorded across studies. We report results only for studies in CBT here. Cognitive behavioural therapy (CBT) versus treatment as usual (TAU) Pain intensity Immediately after treatment, CBT likely demonstrates a small beneficial effect compared to TAU (standardised mean difference (SMD) -0.28, 95% confidence interval (CI) -0.39 to -0.16; 20 studies, 3206 participants; moderate-certainty evidence). Participants receiving CBT are probably more likely to achieve a 30% improvement in pain intensity compared to TAU (23% versus 11%; risk ratio (RR) 2.15, 95% CI 1.62 to 2.85; 5 studies, 1347 participants; moderate-certainty evidence). They may also be more likely to achieve a 50% improvement in pain intensity (6% versus 2%; RR 2.31, 95% CI 1.14 to 4.66; 4 studies, 1229 participants), but the evidence is of low certainty. At follow-up, there is likely little to no difference in pain intensity between CBT and TAU (SMD -0.04, 95% CI -0.17 to 0.09; 8 studies, 959 participants; moderate-certainty evidence). The evidence comparing CBT to TAU on achieving a 30% improvement in pain is very uncertain (40% versus 24%; RR 1.70, 95% CI 0.82 to 3.53; 1 study, 69 participants). No evidence was available regarding a 50% improvement in pain. Functional disability Immediately after treatment, CBT may demonstrate a small beneficial improvement compared to TAU (SMD -0.38, 95% CI -0.53 to -0.22; 14 studies, 2672 participants; low-certainty evidence). At follow-up, there is likely little to no difference between treatments (SMD -0.05, 95% CI -0.23 to 0.14; 3 studies, 461 participants; moderate-certainty evidence). Quality of life Immediately after treatment, CBT may not have resulted in a beneficial effect on quality of life compared to TAU, but the evidence is very uncertain (SMD -0.16, 95% CI -0.43 to 0.11; 7 studies, 1423 participants). There is likely little to no difference between CBT and TAU on quality of life at follow-up (SMD -0.16, 95% CI -0.37 to 0.05; 3 studies, 352 participants; moderate-certainty evidence). Adverse events Immediately after treatment, evidence about the number of people experiencing adverse events is very uncertain (34% in TAU versus 6% in CBT; RR 6.00, 95% CI 2.2 to 16.40; 1 study, 140 participants). No evidence was available at follow-up. Cognitive behavioural therapy (CBT) versus active control Pain intensity Immediately after treatment, CBT likely demonstrates a small beneficial effect compared to active control (SMD -0.28, 95% CI -0.52 to -0.04; 3 studies, 261 participants; moderate-certainty evidence). The evidence at follow-up is very uncertain (mean difference (MD) 0.50, 95% CI -0.30 to 1.30; 1 study, 127 participants). No evidence was available for a 30% or 50% pain intensity improvement. Functional disability Immediately after treatment, there may be little to no difference between CBT and active control on functional disability (SMD -0.26, 95% CI -0.55 to 0.02; 2 studies, 189 participants; low-certainty evidence). The evidence at follow-up is very uncertain (MD 3.40, 95% CI -1.15 to 7.95; 1 study, 127 participants). Quality of life Immediately after treatment, there is likely little to no difference in CBT and active control (SMD -0.22, 95% CI -1.11 to 0.66; 3 studies, 261 participants; moderate-certainty evidence). The evidence at follow-up is very uncertain (MD 0.00, 95% CI -0.06 to 0.06; 1 study, 127 participants). Adverse events Immediately after treatment, the evidence comparing CBT to active control is very uncertain (2% versus 0%; RR 3.23, 95% CI 0.13 to 77.84; 1 study, 135 participants). No evidence was available at follow-up.

AUTHORS' CONCLUSIONS

Currently, evidence about remotely-delivered psychological therapies is largely limited to Internet-based delivery of CBT. We found evidence that remotely-delivered CBT has small benefits for pain intensity (moderate certainty) and functional disability (moderate to low certainty) in adults experiencing chronic pain. Benefits were not maintained at follow-up. Our appraisal of quality of life and adverse events outcomes post-treatment were limited by study numbers, evidence certainty, or both. We found limited research (mostly low to very low certainty) exploring other psychological therapies (i.e. ACT). More high-quality studies are needed to assess the broad translatability of psychological therapies to remote delivery, the different delivery technologies, treatment longevity, comparison with active control, and adverse events.

The Efficacy of Acceptance and Commitment Therapy for Chronic Pain: A Systematic Review and Meta-analysis

OBJECTIVES

Previous meta-analyses of a small number of trials showed that acceptance and commitment therapy (ACT) might improve chronic pain. Many new trials have been published afterward, and the factors that may impact the efficacy of ACT are less understood. We, therefore, conducted an updated systematic review with meta-analysis to investigate the efficacy of ACT for people with chronic pain.

METHODS

Randomized controlled trials that investigated the efficacy of ACT in clinical or community setting for adult populations with chronic pain were included. The methodological quality of trials was assessed with the Cochrane Risk of Bias tool. Standardized mean differences between ACT and comparison groups in their effects on 6 outcomes (ie, pain acceptance, quality of life, pain-related functioning, pain intensity, anxiety, and depression) were pooled across studies.

RESULTS

Of the 3171 records identified, 21 trials with 1962 participants were included for analysis. The comparison groups included active treatment and waitlist control/usual care. The standardized mean difference was 0.67 (95% CI: 0.48, 0.87) for pain acceptance, 0.43 (95% CI: 0.29, 0.57) for quality of life, -0.88 (95% CI: -1.14, -0.63) for pain-related functioning, -0.45 (95% CI: -0.62, -0.27) for pain intensity, -0.35 (95% CI: -0.54, -0.15) for anxiety, and -0.74 (95% CI, -0.98, -0.50) for depression, all favoring ACT. Subgroup analyses showed that the effects were statistically significant across almost all subgroups and for some outcomes were greater in the trials conducted in people with a specific diagnosis (as compared with those conducted in people with general chronic pain), the trials with waitlist or usual care control, the trials with a greater number of sessions of ACT, and the trials with a longer ACT intervention.

DISCUSSION

ACT is effective and comparable to, if not better than, some other available active treatments for chronic pain.

The Influence of the Fear of Negative Evaluation on Activity Avoidance in Fibromyalgia: Exploring Pain Acceptance and Positive Affect as Resilience Variables

To examine the mediating role of pain acceptance (PAcc) between fear of negative evaluation (FNE) and activity avoidance (AV) at different levels of positive affect (PA) (moderator) among women diagnosed with fibromyalgia (FM) (moderate mediation model). This study was cross-sectional in design. A convenience sample of women with FM (n = 231) completed measures of pain severity, FNE, PAcc, AV, and PA. A simple mediation model and a moderate mediation model was constructed and analyzed using the SPSS macro-PROCESS. First, PAcc mediated the effect of FNE on AV (β = .02, SE = 0.008; [95% CI [0.0075, 0.0394]). Second, a mediated effect of PAcc between FNE and AV moderated by PA at medium and high levels of PA were found (m: 0.23; β = -.22, p = .0006; h: 9.59; β = -.34, p = .0002. Future work should seek to validate study findings in diverse samples of FM patients. Additionally, future work should explore how FM self-management interventions that include PAcc can promote increased activity among women suffering from FM with medium to high levels of PA.

eHealth Interventions to Support Self-Management in People With Musculoskeletal Disorders, "eHealth: It's TIME"-A Scoping Review

OBJECTIVE

eHealth-mediated interventions have been proposed as one option to support self-management in those with musculoskeletal disorders (MSDs). This scoping review aimed to chart the evidence regarding eHealth modalities, musculoskeletal diagnosis, and outcomes of eHealth-mediated self-management support interventions in persons with MSDs and identify any gaps within the literature.

METHODS

Six electronic databases (MEDLINE, CINAHL, PsycINFO, Embase, Scopus, and the Cochrane Database of Systematic Reviews), 7 grey literature sources (eg, OpenGrey), and reference and citation lists of included studies were searched from database inception to July 2020. Published studies of adult participants with a MSD utilizing an eHealth intervention to support self-management were included. Studies were limited to those published in English. Two reviewers independently screened all studies. Data were extracted by 1 reviewer and reviewed by another reviewer.

RESULTS

After screening 3377 titles and abstracts followed by 176 full texts, 87 studies fulfilled the eligibility criteria. The majority were published in the last 5 years (n = 48; 55%), with almost one-third originating in the United States (n = 28; 32%). The most common eHealth modality type was internet based (n = 22; 35%), with almost one-half (n = 41; 47%) of the included studies involving participants with widespread musculoskeletal symptoms. The most commonly reported outcomes were related to body functions (ie, pain intensity) (n = 67; 45%), closely followed by activities and participation (ie, function) (n = 65; 44%), with environmental factors (ie, health care utilization) the least commonly reported (n = 17; 20%).

CONCLUSIONS

There is considerable variation within the eHealth-mediated self-management support intervention literature. Research is needed on the role of eHealth-mediated self-management support interventions across a broad range of MSDs to guide clinical practice.

IMPACT

This scoping review has identified gaps in the literature relating to specific eHealth modalities, musculoskeletal diagnoses, and health care utilization data, which should guide future research.

The Process of Learning Mindfulness and Acceptance through the Use of a Mobile App Based on Acceptance and Commitment Therapy: A Grounded Theory Analysis

This study aimed to explore the process of how college student military veterans with posttraumatic stress disorder (PTSD) symptoms learn mindfulness and acceptance through the use of a mobile app based on acceptance and commitment therapy (ACT). Twenty-three college student veterans with PTSD symptoms participated in the 4-week ACT mobile app-based intervention and took part in three weekly semi-structured interviews. Results of the grounded theory data analysis reveal the core category of Mindful Scaffolding, a process indicating how student veterans cope with the interruptions and intrusions associated with learning mindfulness and acceptance through the use of the ACT-based app. The grounded theory provides a foundational theoretical framework for increasing adherence with using mindfulness- and acceptance-based mobile app interventions for PTSD.

Cognitive-Affective Transdiagnostic Factors Associated With Vulnerability to Alcohol and Prescription Opioid Use in the Context of Pain

The use of alcohol and prescription opioids is common among people in pain and poses significant public health burdens. This review identifies factors associated with motivation to use alcohol and prescription opioids in the context of pain. Pain-relevant, cognitive-affective, transdiagnostic vulnerability factors-expectancies/motives, pain catastrophizing, pain-related anxiety, distress intolerance, anxiety sensitivity, and perceived interrelations-were selected from theoretical conceptualizations of pain and substance use. Searches conducted in PubMed, PsycINFO, and Embase returned 25 studies that examined associations between identified variables of interest and the use of alcohol and prescription opioids in the context of pain. Consistent with a larger literature on pain and substance use, the studies included in this review demonstrated that people with chronic pain are motivated to use alcohol and opioids in response to negative affect and hold expectancies/motives for coping with pain. Vulnerabilities that engender difficulty managing aversive internal states (distress intolerance and anxiety sensitivity) and maladaptive responses to pain (pain-related anxiety and pain catastrophizing) also were implicated in motivation for alcohol and opioid use. Although one study found that pain-related anxiety was associated with co-use of alcohol and opioids, no studies examined simultaneous use. Future research directions that can explicate causal associations, identify patterns of alcohol and opioid co-use, clarify the role of pain in cessation processes, and inform treatment development are discussed.

A systematic review of internet-based interventions for women with chronic pain

Introduction

To evaluate the effects of internet-based interventions on physical and psychosocial outcomes in women with chronic pain through a systematic review.

Method

A search of the following electronic databases: PubMed/MEDLINE, ScienceDirect, and Web of Science. Two different authors separately tabulated the indices selected in identical predetermined forms. The methodological quality of all randomised trials was assessed using the Cochrane Collaboration’s tool for assessing the risk of bias.

Results

Seven articles were finally included. The main features of interventions included online cognitive-behavioural and/or psychoeducation therapy to improve health with an interactive component. The methodological quality showed a high risk of bias, mainly from a lack of blinding.

Conclusion

There are indicators that suggest that internet-based interventions may be useful for women with chronic pain. However, the validity of such a conclusion is limited as most trials included had a high risk of bias. More rigorous research is required before stating that such interventions can overcome the current limitations of traditional face-to-face care.

An integrative review of personalized feedback interventions for pain and alcohol

Interrelations between pain and alcohol consumption are considered to be bidirectional in nature, leading to greater pain and increased drinking over time. Personalized feedback interventions (PFIs), which typically aim to motivate behavior change via presentation of personalized and normative feedback, hold great promise for integrated treatment. There has been no previous review of PFIs for pain, and limited work has focused on examining the utility of PFIs for more established, adult drinkers. Our review of the literature revealed that brief, computer-based PFIs can improve pain outcomes and decrease problematic alcohol consumption. Future research would likely benefit from developing integrated, computer-based PFIs for pain and alcohol misuse. Such approaches offer potential for broad impact, while simultaneously reducing patient and healthcare provider burden.
