RESUMEN

BACKGROUND: Chronic low back pain (CLBP) is a significant problem affecting millions of people worldwide. Three widely implemented psychological techniques used for CLBP management are cognitive therapy (CT), mindfulness meditation (MM), and behavioral activation (BA). This study aimed to evaluate the relative immediate (pre- to post-treatment) and longer term (pre-treatment to 3- and 6-month follow-ups) effects of group, videoconference-delivered CT, BA, and MM for CLBP. METHODS: This is a secondary analysis of a three-arm, randomized clinical trial comparing the effects of three active treatments-CT, BA, and MM-with no inert control condition. Participants were N = 302 adults with CLBP, who were randomized to condition. The primary outcome was pain interference, and other secondary outcomes were also examined. The primary study end-point was post-treatment. Intent-to-treat analyses were undertaken for each time point, with the means of the changes in outcomes compared among the three groups using an analysis of variance (ANOVA). Effect sizes and confidence intervals are also reported. RESULTS: Medium-to-large effect size reductions in pain interference were found within BA, CT, and MM (ds from - .71 to - 1.00), with gains maintained at both follow-up time points. Effect sizes were generally small to medium for secondary outcomes for all three conditions (ds from - .20 to - .71). No significant between-group differences in means or changes in outcomes were found at any time point, except for change in sleep disturbance from pre- to post-treatment, improving more in BA than MM (d = - .49). CONCLUSIONS: The findings from this trial, one of the largest telehealth trials of psychological treatments to date, critically determined that group, videoconference-delivered CT, BA, and MM are effective for CLBP and can be implemented in clinical practice to improve treatment access. The pattern of results demonstrated similar improvements across treatments and outcome domains, with effect sizes consistent with those observed in prior research testing in-person delivered and multi-modal psychological pain treatments. Thus, internet treatment delivery represents a tool to scale up access to evidence-based chronic pain treatments and to overcome widespread disparities in healthcare. TRIAL REGISTRATION: Clinicaltrials.gov, NCT03687762.

RESUMEN

PURPOSE/OBJECTIVE: This study sought to develop and evaluate the psychometric properties of a brief measure of the quality of therapist treatment delivery that would be applicable for use across different types of psychosocial chronic pain treatments: the Therapist Quality Scale (TQS). RESEARCH METHOD/DESIGN: An initial pool of 14 items was adapted from existing measures, with items selected that are relevant across interventions tested in a parent trial comparing an 8-week, group, Zoom-delivered mindfulness meditation, cognitive therapy, and behavioral activation for chronic back pain from which data for this study were obtained. A random selection of 25% of video-recorded sessions from each cohort was coded for therapist quality (two randomly selected sessions per group), with 66 sessions included in the final analyses (n = 33 completed pairs). Items were coded on a 7-point Likert-type scale. Exploratory factor analysis (EFA) and reliability estimates were generated. RESULTS: EFA showed a single-factor solution that provided a parsimonious explanation of the correlational structure for both sessions. Eight items with factor loadings of ≥ .60 in both sessions were selected to form the TQS. Reliability analyses demonstrated all items contributed to scale reliability, and internal consistency reliabilities were good (αs ≥ .86). Scores for the eight-item TQS from the two sessions were significantly correlated (r = .59, p < .001). CONCLUSIONS/IMPLICATIONS: The TQS provides a brief measure with preliminary psychometric support that is applicable for use across different types of treatments to rate the quality of the therapist's delivery. The items assess quality in delivering specific techniques, maintaining session structure, and in developing and maintaining therapeutic rapport.

RESUMEN

Psychosocial interventions for people with chronic pain produce significant improvements in outcomes, but these effects on average are modest with much variability in the benefits conferred on individuals. To enhance the magnitude of treatment effects, characteristics of people that might predict the degree to which they respond more or less well could be identified. People with chronic low back pain (N = 521) participated in a randomized controlled trial which compared cognitive therapy, mindfulness-based stress reduction, behavior therapy and treatment as usual. Hypotheses regarding predictors and/or moderators were based on the Limit, Activate, and Enhance model; developed to predict and explain moderators/predictors of psychosocial pain treatments. Results were: 1) low levels of cognitive/behavioral function at pre-treatment predicted favorable pre- to post-treatment outcomes; 2) favorable expectations of benefit from treatment and sound working alliances predicted favorable pre- to post-treatment outcomes; 3) women benefited more than men. These effects emerged without regard to treatment condition. Of note, high levels of cognitive/behavioral function at pre-treatment predicted favorable outcomes only for people in the treatment as usual condition. Analyses identified a set of psychosocial variables that may act as treatment predictors across cognitive therapy, mindfulness-based stress reduction and behavior therapy, as hypothesized by the Limit, Activate, and Enhance model if these 3 treatments operate via similar mechanisms. Findings point toward people who may and who may not benefit fully from the 3 psychosocial treatments studied here, and so may guide future research on matching people to these kinds of psychosocial approaches or to other (eg, forced-based interventions) non-psychosocial approaches. TRIAL REGISTRATION: The ClinicalTrials.gov Identifier is NCT02133976. PERSPECTIVE: This article examines potential predictors/moderators of response to psychosocial treatments for chronic pain. Results could guide efforts to match people to the most effective treatment type or kind.

RESUMEN

OBJECTIVE: Cognitive therapy (CT), mindfulness-based stress reduction (MBSR), and behavior therapy (BT) for chronic pain treatment produce outcome improvements. Evidence also suggests that changes in putative therapeutic mechanisms are associated with changes in outcomes. Nonetheless, methodological limitations preclude clear understanding of how psychosocial chronic pain treatments work. In this comparative mechanism study, we examined evidence for specific and shared mechanism effects across the three treatments. METHOD: CT, MBSR, BT, and treatment as usual (TAU) were compared in people with chronic low back pain (N = 521). Eight individual sessions were administered with weekly assessments of "specific" mechanisms (pain catastrophizing, mindfulness, behavior activation) and outcomes. RESULTS: CT, MBSR, and BT produced similar pre- to posttreatment effects on all mechanism variables, and all three active treatments produced greater improvements than TAU. Participant ratings of expectations of benefit and working alliance were similar across treatments. Lagged and cross-lagged analyses revealed that prior week changes in both mechanism and outcome factors predicted next week changes in their counterparts. Analyses of variance contributions suggested that changes in pain catastrophizing and pain self-efficacy were consistent unique predictors of subsequent outcome changes. CONCLUSIONS: Findings support the operation of shared mechanisms over specific ones. Given significant lagged and cross-lagged effects, unidirectional conceptualizations-mechanism to outcome-need to be expanded to include reciprocal effects. Thus, prior week changes in pain-related cognitions could predict next week changes in pain interference which in turn could predict next week changes in pain-related cognitions, in what may be an upward spiral of improvement.

RESUMEN

ABSTRACT: Trials of cognitive therapy (CT), mindfulness-based stress reduction (MBSR), and behavior therapy (BT) suggest that all 3 treatments produce reductions in pain and improvements in physical function, mood, and sleep disturbance in people with chronic pain conditions. Fewer studies have compared the relative efficacies of these treatments. In this randomized controlled study, we compared CT, MBSR, BT, and treatment as usual (TAU) in a sample of people with chronic low back pain (N = 521). Eight individual sessions were administered with weekly assessments of outcomes. Consistent with the prior work, we found that CT, MBSR, and BT produced similar pretreatment to posttreatment effects on all outcomes and revealed similar levels of maintenance of treatment gains at 6-month follow-up. All 3 active treatments produced greater improvements than TAU. Weekly assessments allowed us to assess rates of change; ie, how quickly a given treatment produced significant differences, compared with TAU, on a given outcome. The 3 treatments differed significantly from TAU on average by session 6, and this rate of treatment effect was consistent across all treatments. Results suggest the possibility that the specific techniques included in CT, MBSR, and BT may be less important for producing benefits than people participating in any techniques rooted in these evidence-based psychosocial treatments for chronic pain.

RESUMEN

ABSTRACT: Research on intersectionality and chronic pain disparities is very limited. Intersectionality explores the interconnections between multiple aspects of identity and provides a more accurate image of disparities. This study applied a relatively novel statistical approach (ie, Latent Class Analysis) to examine chronic pain disparities with an intersectional identity approach. Cross-sectional data were analyzed using pretreatment data from the Learning About My Pain trial, a randomized comparative effectiveness study of group-based psychosocial interventions (Patient-Centered Outcomes Research Institute Contract #941, Beverly Thorn, PI; clinicaltrials.gov identifier NCT01967342) for patients receiving care for chronic pain at low-income clinics in rural and suburban Alabama. Latent Class Analysis results suggested a 5-class model. To easily identify each class, the following labels were created: older adults, younger adults, severe disparity, older Black or African American, and Working Women. The latent disparity classes varied by pretreatment chronic pain functioning. Overall, the severe disparity group had the lowest levels of functioning, and the Working Women group had the highest levels of functioning. Although younger and with higher literacy levels, the younger adults group had similar levels of pain interference and depressive symptoms to the severe disparity group (P's < 0.05). The younger adults group also had higher pain catastrophizing than the older adults group (P < 0.005). Results highlighted the importance of the interactions between the multiple factors of socioeconomic status, age, and race in the experience of chronic pain. The intersectional identity theory approach through Latent Class Analysis provided an integrated image of chronic pain disparities in a highly understudied and underserved population.

RESUMEN

PURPOSE/OBJECTIVE: This study reports a qualitative analysis of patient experiences following cognitive therapy (CT), mindfulness meditation (MM), or mindfulness-based cognitive therapy (MBCT) for chronic low back pain (CLBP). It aimed to investigate the procedural elements reported by participants as important across these approaches, as well as the role of treatment-related change processes and common factors. Research Method/Design: A qualitative analysis of posttreatment semistructured interviews was conducted with participants who enrolled in a randomized controlled trial comparing MM, CT, and MBCT (N = 57 adults with CLBP). A thematic analysis of transcribed interviews was undertaken by two independent coders; emerging themes, subthemes, and direct quotes were collated, and thematic maps were created. RESULTS: Procedural elements that were both unique (e.g., "cognitive restructuring" in CT) and shared among the three treatments (e.g., "knowledge gained" on pain-related topics) were reported as important. Each treatment was associated with a small number of unique therapeutic processes that were consistent with theoretical tenets underlying the interventions (e.g., "staying in the present moment" in MM). A large number of shared processes and common factors also emerged as important across all three treatments. CONCLUSIONS/IMPLICATIONS: These first-person accounts provide insight into those participant-identified therapeutic procedures and change processes that were most valued by individuals completing cognitive and mindfulness-based interventions for CLBP. Early identification of treatment barriers and strategies to overcome these barriers is necessary. Further, therapeutic rapport and training participants in coping skills they themselves can use were critical, as was engendering changes in cognitive, emotional, and behavioral mechanisms.

RESUMEN

ABSTRACT: Psychosocial treatments for chronic pain produce favorable outcomes. However, we still do not know precisely by what mechanisms or techniques these outcomes are wrought. In secondary analyses of a 10-week group intervention study comparing the effects of literacy-adapted cognitive behavioral therapy (CBT) with literacy-adapted pain education (EDU) among patients with chronic pain, low-socioeconomic status, and low literacy, the Learning About My Pain trial, we examined whether pain catastrophizing was a mechanism specific to CBT. Participants (N = 168) completed mechanism and outcome measures weekly for the 10 weeks of group treatment. Analyses revealed that (1) pain catastrophizing was reduced similary across CBT and EDU; (2) lagged analyses indicated that previous week reductions in pain catastrophizing predicted next week reductions in pain intensity and pain interference; (3) cross-lagged analyses indicated that previous week reductions in pain intensity and interference predicted next week reductions in pain catastrophizing; and (4) the relationships between pain catastrophizing and pain intensity and interference were moderated by session progression such that these links were strong and significant in the first third of treatment, but weakened over time and became nonsignificant by the last third of treatment. Results suggest the existence of reciprocal influences whereby cognitive changes may produce outcome improvements and vice versa. At the same time, results from analyses of changes in slopes between pain catastrophizing and outcomes indicated that CBT and EDU were successful in decoupling pain catastrophizing and subsequent pain intensity and interference as treatment progressed. Results provide further insights into how psychosocial treatments for chronic pain may work.

RESUMEN

This is a secondary data analysis of a subgroup of participants who received the Learning About My Pain (LAMP) intervention (clinicaltrials.gov identifier NCT01967342). We examined the effects of LAMP on pre-to-post changes in biomedical and biopsychosocial pain conceptualization and whether those changes in pain conceptualization were associated with physical and psychological functioning. Participants were randomized into three conditions: Cognitive Behavioral Therapy (CBT), Pain Psychoeducation (EDU), or Usual Medical Care (UC). Results based on 225 participants who completed the Pain Concepts Questionnaire (PCQ) showed a pre-to-post reduction in biomedical pain conceptualization (BM), an increase in biopsychosocial pain conceptualization (BPS), and an increase in BPS/BM ratio for CBT and EDU but not UC. There were no differences between CBT and EDU in post-treatment PCQ scores. Compared to those with lower BM pain beliefs scores at post-treatment, participants endorsing higher BM pain beliefs scores reported greater pain intensity and greater pain interference. Furthermore, higher BM pain beliefs scores at post-treatment and lower BPS/BM ratio were associated with higher levels of pain catastrophizing. Overall, results of this study suggest the need for targeting specific pain beliefs that influence pain-related outcomes. PERSPECTIVE: This article presents the potential benefits of providing literacy-adapted psychosocial treatments to expand pain conceptualization beyond a biomedical-only understanding and toward a biopsychosocial conceptualization of the experience of pain. Furthermore, the association of changes in pain conceptualization and pain-related functioning argues for its potential clinical relevance.

RESUMEN

BACKGROUND: Women with breast cancer in medically underserved areas are particularly vulnerable to persistent pain and disability. Behavioral pain interventions reduce pain and improve outcomes. Cancer patients in medically underserved areas receive limited adjunctive cancer care, as many lack access to pain therapists trained in behavioral interventions, face travel barriers to regional medical centers, and may have low literacy and limited resources. mHealth technologies have the potential to decrease barriers but must be carefully adapted for, and efficacy-tested with, medically underserved patients. We developed an mHealth behavioral pain coping skills training intervention (mPCST-Community). We now utilize a multisite randomized controlled trial to: 1) test the extent mPCST-Community reduces breast cancer patients' pain severity (primary outcome), pain interference, fatigue, physical disability, and psychological distress; 2) examine potential mediators of intervention effects; and 3) evaluate the intervention's cost and cost-effectiveness. METHODS/DESIGN: Breast cancer patients (N = 180) will be randomized to mPCST-Community or an attention control. mPCST-Community's four-session protocol will be delivered via videoconferencing at an underserved community clinic by a remote pain therapist at a major medical center. Videoconference sessions will be supplemented with a mobile application. Participants will complete self-report measures at baseline, post-intervention, and 3- and 6-month follow-ups. CONCLUSIONS: mPCST-Community has the potential to reduce pain and disability, and decrease barriers for cancer patients in medically underserved areas. This is one of the first trials to test an mHealth behavioral cancer pain intervention developed specifically for medically underserved communities. If successful, it could lead to widespread implementation and decreased health disparities.

RESUMEN

The examination of pain beliefs for chronic pain assessment and treatment has been a growing area of interest. A variety of questionnaires have been developed to assess pain beliefs, however, these questionnaires often require high levels of literacy and education. The pain concepts questionnaire (PCQ) was developed with literacy-adaptations to better evaluate pain beliefs in a low socioeconomic (SES) population. This study is an initial exploratory evaluation of the PCQ in a sample of patients with chronic pain and multiple disparities as part of the learning about my pain (LAMP) trial, a randomized controlled trial comparing literacy-adapted psychosocial treatments for chronic pain. All data were collected at pretreatment. Exploratory factor analysis was performed to examine the underlying factor structure of the PCQ and cross-sectional correlational analyses examined relationships between pain beliefs with sociodemographic factors and chronic pain-related variables. Results suggested a 2-factor solution with a Biopsychosocial factor and Biomedical factor. Consistent with the literature, correlational analyses highlighted racial and SES disparities in pain beliefs and the importance of beliefs in pain- and cognitive/affective-related functioning. The study emphasizes the importance of pain beliefs in chronic pain management and recommends future research to further examine additional psychometric properties of the PCQ. PERSPECTIVE: This study is an initial evaluation of the psychometric properties of a new measure of chronic pain beliefs, the pain concepts questionnaire (PCQ). The PCQ is literacy-adapted and was assessed within a low-SES population. Psychometric proprieties of this measure were promising and could be useful in pain assessment and interventions.

RESUMEN

OBJECTIVES: The goals of the study were to determine to what degree changes in pain-related cognition during cognitive behavioral treatment (CBT) and pain education (EDU) represented treatment mechanisms and whether these cognitive changes worked to a larger extent to produce favorable outcomes in CBT than in EDU. METHOD: Reported here are secondary analyses of a randomized control trial (N = 290) comparing CBT, EDU, and treatment as usual for low-literacy, low-socioeconomic-status people with chronic pain. We excluded the treatment as usual condition from these analyses and included measures collected at a midtreatment epoch. Treatment was 10 weekly group sessions. RESULTS: Linear mixed models revealed nonsignificant differences in pre- to mid- to posttreatment changes in pain catastrophizing and pain self-efficacy between CBT and EDU. The same was true for outcome measures. Cross-lagged analyses revealed significant relationships between pre- to midtreatment changes in catastrophizing and self-efficacy and mid- to posttreatment changes in outcomes. However, relationships between pre- to midtreatment changes in outcomes and mid- to posttreatment changes in catastrophizing and self-efficacy were also significant. CONCLUSIONS: Results suggest a complex set of mechanistic relationships. Instead of a unidirectional path from designated mechanism to designated outcome, our results suggest reciprocal influences whereby cognitive changes may beget outcome improvements and vice versa. Results also suggest that cognitive changes do not occur solely in a treatment that uses cognitive restructuring to foster such changes but may occur as a function of providing people with detailed information regarding the biopsychosocial nature of chronic pain.

RESUMEN

OBJECTIVES: This study evaluated theoretically derived mechanisms and common therapeutic factors to test their role in accounting for pain-related outcome change during group-delivered cognitive therapy, mindfulness meditation, and mindfulness-based cognitive therapy for chronic low back pain. METHODS: A secondary analysis of a pilot randomized controlled trial was used to explore the primary mechanisms of pretreatment to posttreatment changes in pain control beliefs, mindful observing, and pain catastrophizing, and the secondary common factor mechanisms of therapeutic alliance, group cohesion, and amount of at-home skill practice during treatment. The primary outcome was pain interference; pain intensity was a secondary outcome. RESULTS: Large effect size changes in the 3 primary mechanisms and the outcome variables were found across the conditions. Across all 3 treatment conditions, change in pain control beliefs and pain catastrophizing were significantly associated with improved pain interference, but not pain intensity. Therapeutic alliance was significantly associated with pain intensity improvement and change in the therapy-specific mechanisms across the 3 conditions. Mindful observing, group cohesion, and amount of at-home practice were not significantly associated with changes in the outcomes. DISCUSSION: Cognitive therapy, mindfulness meditation, and mindfulness-based cognitive therapy for chronic low back pain were all associated with significant changes in the primary mechanisms to a similar degree. Change in perceived pain control and pain catastrophizing emerged as potential "meta-mechanisms" that might be a shared pathway that contributes to improved pain-related outcomes across treatments. Further, strong working alliance may represent a critical therapeutic process that both promotes and interacts with therapeutic techniques to influence outcome.

RESUMEN

The purpose of the ongoing trial is to improve care of older Veterans with chronic low back pain (CLBP, i.e., low back pain for ≥6 months on ≥ half the days). Current CLBP care is limited by being either overly spine-focused or non-specifically prescribed and both approaches frequently lead to suboptimal reduction in pain and improvement in function. Through prior studies we have laid the foundation for a patient-centered approach to care for older Veterans with CLBP in which the spine is a source of vulnerability but not the sole treatment target. The approach considers CLBP a geriatric syndrome, a final common pathway for the expression of multiple contributors rather than a disease of the spine. We describe here the rationale and design of a randomized controlled trial to test the efficacy of an older Veteran-centered approach to CLBP care in "Aging Back Clinics (ABCs)" compared with Usual Care (UC). Three hundred thirty Veterans age 65-89 with CLBP will be randomized to ABCs or UC and followed for 12 months after randomization. We will assess the impact of ABCs on our primary outcome of pain-associated disability with the Oswestry Disability Index at 6 and 12 months, and secondary outcomes of pain intensity, health-related quality of life, balance confidence, mobility and healthcare utilization. If shown efficacious, the approach tested in ABCs has the potential to transform the care of older adults with CLBP by improving the quality of life for millions, reducing morbidity and saving substantial healthcare costs.

RESUMEN

This study examined psychosocial pain treatment moderation in a secondary analysis of a trial that compared cognitive therapy (CT), mindfulness-meditation (MM), and mindfulness-based cognitive therapy (MBCT) for chronic low back pain (CLBP). The Limit, Activate, and Enhance (LA&E) model of moderation provided a framework for testing a priori hypotheses. Adult participants (N = 69) with CLBP completed a pretreatment assessment of hypothesized moderators: pain catastrophizing, brain state as assessed by electroencephalogram, mindful observing, and nonreactivity. Outcomes were pain interference, characteristic pain intensity, physical function, and depression, assessed at pre- and post-treatment. Moderation analyses found significant interaction effects, specifically: 1) higher and lower baseline pain catastrophizing was associated with greater improvement in pain intensity in MM and MBCT, respectively; 2) higher baseline theta power was associated with greater improvement in depression in MBCT and interfered with response to CT; 3) lower baseline nonreactivity was associated with greater improvement in physical function in MM while higher nonreactivity was associated with greater improvement in MBCT. The findings support the possibility that different patients are more or less likely to benefit from various treatments. Theory-driven moderation research has the capacity to inform the development of patient-treatment matching algorithms to optimize outcome. PERSPECTIVE: This study presents preliminary findings from theory-driven tests of the moderators of mindfulness meditation, cognitive therapy, and mindfulness-based cognitive therapy for chronic low back pain. The results of such analyses may inform the understanding of for whom various evidence-based psychosocial pain treatments may engender the most meaningful benefits.

RESUMEN

Differences among patients can moderate the impact of evidence-based treatments (ie, heterogeneity of treatment effects), leading patients to get more or less benefit. The Learning About My Pain study was a randomized, comparative effectiveness trial of a 10-week literacy-adapted group cognitive-behavioral therapy for chronic pain (CBT) versus pain psychoeducation groups (EDU) versus usual medical care. We examined potential sociodemographic and cognitive moderators of treatment effect among participants with post-treatment assessments (N = 241). Analyses were conducted using moderation in the PROCESS macro in SPSS and significant interactions were explored further. Education and primary literacy moderated the difference between CBT and EDU on pain intensity, and primary literacy, health literacy, and working memory moderated the difference between CBT and EDU on pain interference. Analyses revealed few significant moderation effects relative to usual medical care. No moderators were identified for depression. Neither sex nor minority status moderated any differences between groups. Patients with lower education, literacy, and working memory gained more benefit from CBT than EDU. When provided sufficient guidance and structure in a way that is meaningfully adapted, highly disadvantaged patients achieved as much benefit as less disadvantaged patients, suggesting that the literacy-adapted CBT more successfully met the needs of this population. TRIAL REGISTRATION: clinicaltrials.gov identifier NCT01967342 PERSPECTIVE: This article presents findings related to heterogeneity of treatment effects for simplified group psychosocial treatments for chronic pain. The results suggest that educationally, cognitively, or literacy disadvantaged patients benefit most from the more structured approach of literacy-adapted CBT rather than EDU, whereas less disadvantaged patients benefit from either treatment.

RESUMEN

OBJECTIVE: This pilot trial compared the feasibility, tolerability, acceptability, and effects of group-delivered mindfulness meditation (MM), cognitive therapy (CT), and mindfulness-based cognitive therapy (MBCT) for chronic low back pain (CLBP). SETTING: University of Queensland Psychology Clinic. SUBJECTS: Participants were N = 69 (intent-to-treat [ITT] sample) adults with CLBP. DESIGN: A pilot, assessor-blinded randomized controlled trial. METHODS: Participants were randomized to treatments. The primary outcome was pain interference; secondary outcomes were pain intensity, physical function, depression, and opioid medication use. The primary study end point was post-treatment; maintenance of gains was evaluated at three- and six-month follow-up. RESULTS: Ratings of acceptability, and ratios of dropout and attendance showed that MBCT was acceptable, feasible, and well tolerated, with similar results found across conditions. For the ITT sample, large improvements in post-treatment scores for pain interference, pain intensity, physical function, and depression were found (P < 0.001), with no significant between-group differences. Analysis of the follow-up data (N = 43), however, revealed that MBCT participants improved significantly more than MM participants on pain interference, physical function, and depression. The CT group improved more than MM in physical function. The MBCT and CT groups did not differ significantly on any measures. CONCLUSIONS: This is the first study to examine MBCT for CLBP management. The findings show that MBCT is a feasible, tolerable, acceptable, and potentially efficacious treatment option for CLBP. Further, MBCT, and possibly CT, could have sustained benefits that exceed MM on some important CLBP outcomes. A future definitive randomized controlled trial is needed to evaluate these treatments and their differences.

RESUMEN

The purpose of this study was to refine and test a mobile-health behavioral cancer pain coping skills training protocol for women with breast cancer and pain from medically underserved areas. Three focus groups (Phase 1) were used to refine the initial protocol. A single-arm pilot trial (Phase 2) was conducted to assess feasibility, acceptability, and changes in outcomes. The intervention was delivered at a community-based clinic via videoconferencing technology. Participants were women (N = 19 for Phase 1 and N = 20 for Phase 2) with breast cancer and pain in medically underserved areas. Major themes from focus groups were used to refine the intervention. The refined intervention demonstrated feasibility and acceptability. Participants reported significant improvement in pain severity, pain interference, and self-efficacy for pain management. Our intervention is feasible, acceptable, and likely to lead to improvement in pain-related outcomes for breast cancer patients in medically underserved areas. Implications for Psychosocial Oncology Practice Breast cancer patients being treated in medically underserved areas have a dearth of exposure to behavioral interventions that may improve their ability to manage pain. Evidence from this single-arm pilot trial suggests that our mobile-health behavioral cancer pain coping skills training protocol is acceptable and feasible in this vulnerable population. Appropriately adapted mobile-health technologies may provide an avenue to reach underserved patients and implement behavioral interventions to improve pain management.
