Variability of Hepatitis C Treatment Cascade Outcomes among People Who Inject Drugs across Geographically Diverse Clinics in the US: The HERO Study.

Heterogeneity of outcomes across different clinical trial study sites is often inevitable. Understanding how outcomes differ by site is important for planning future programs and studies. We examined the extent of heterogeneity of hepatitis C virus (HCV) treatment cascade outcomes among persons who inject drugs (PWIDs) across sixteen clinical sites utilized in the HERO Study-a pragmatic randomized trial of HCV treatment support. Treatment cascade outcomes included averages of overall treatment adherence and proportions of treatment initiation, treatment completion, sustained virologic response (SVR) test completion, and SVR achievement. The HERO study utilized 16 clinical sites across the United States (US): eight opioid treatment programs (OTPs) and eight community health centers (CHCs). Variability of the outcomes across the 16 clinical sites was assessed using ranges and intraclass correlation coefficients (ICC) estimated from mixed-effects linear or logistic regression models. Treatment initiation was analyzed in the intention-to-treat (ITT) sample (N = 755); treatment completion, adherence, and SVR test completion in the modified ITT (mITT) sample, which is the sample that initiated treatment (N = 623); and SVR achievement in the mITT and per-protocol (PP, N = 501) samples. Across the 16 clinical sites, the range observed in the averages of overall treatment adherence was from 68% to 81% [ICC = 0.026 (0.005, 0.054)], and the ranges of proportions observed were from 68% to 96% for treatment initiation [ICC (95% CI) = 0.086 (0.051, 0.155)], 60% to 100% for treatment completion [ICC = 0.049 (0.008, 0.215)], 54% to 95% for SVR test completion [ICC = 0.096 (0.006, 0.177)], 46% to 90% for SVR achievement in the mITT sample [ICC = 0.070 (0.014, 0.122)], and 76% to 100% for SVR achievement in the PP sample [ICC = 0.143 (0.021, 0.422)]. The variability of the outcomes across 16 US sites treating HCV among PWIDs appears to be substantial in view of the ranges and ICC values of the outcomes. It is imperative to develop tailored interventions to target the sources of variability and reduce barriers at the patient, provider, clinic, and state policy levels to facilitate more equitable access to HCV treatment and reduce heterogeneity in treatment outcomes.

Effect of self-efficacy among persons who inject drugs treated with direct-acting antivirals on Hepatitis C treatment initiation, duration, completion, adherence, and cure.

BACKGROUND: Self-efficacy, a patient-level factor, has been shown to facilitate patient engagement in treatment and optimize treatment-related outcomes in various health contexts. Research on interventions supporting hepatitis C virus (HCV) direct-acting antiviral (DAA) treatment uptake and adherence among persons who inject drugs (PWID) is needed, but whether self-efficacy factors influence DAA treatment cascade outcomes in this population has been less studied. METHODS: Using the HERO study data, we analyzed a subset of participants with any general health self-efficacy data (n=708) measured at baseline and end-of-treatment time points using a 5-items instrument (facets: 'goal setting', 'goal attainment', 'having a positive effect', 'being in control', and 'working to improve'). The cascade outcomes included DAA treatment initiation, duration, adherence, completion, and sustained virologic response (SVR). The effect of baseline and change (Δ) scores for composite and item-level self-efficacy on the cascade outcomes was assessed using logistic regression and generalized linear models. RESULTS: Higher baseline composite self-efficacy [adjusted odds ratio (95 % confidence interval) =1.57 (1.07, 2.29)], 'goal attainment' [1.31 (1.03, 1.67)] and 'having a positive effect' [1.33 (1.03, 1.74)] were associated with greater likelihood of treatment initiation. 'Δ Goal attainment' was significantly associated with SVR [1.63 (1.04, 2.53)]. 'Δ Being in control' and 'Δ working to improve' were associated with treatment adherence and duration, respectively. CONCLUSIONS: General health self-efficacy positively influences DAA treatment initiation among PWID. 'Goal attainment' facilitates the achievement of DAA treatment-related outcomes. Further studies should assess the effect of self-efficacy related to performing healthcare tasks specific to DAAs on the treatment-related outcomes.

Web-Based Mindfulness-Based Cognitive Therapy for Adults With a History of Depression: Protocol for a Randomized Controlled Trial.

BACKGROUND: Depression poses a major threat to public health with an increasing prevalence in the United States. Mindfulness-based interventions, such as mindfulness-based cognitive therapy (MBCT), are effective methods for managing depression symptoms and may help fortify existing efforts to address the current disease burden. The in-person group format of MBCT, however, incurs barriers to care such as expenses, childcare needs, and transportation issues. Alternate delivery modalities such as MBCT delivered via the web can be investigated for their capacity to overcome these barriers and still reduce symptoms of depression with adequate feasibility and efficacy. OBJECTIVE: This study protocol aims to examine the feasibility and efficacy of MBCT delivered via the web for the treatment of depression. METHODS: To attain study aims, 2 phases will be implemented using a waitlist control design. A total of 128 eligible participants will be randomized into either an 8-week MBCT intervention group plus treatment as usual (MBCT + TAU; group 1) or an 8-week waitlist control group (group 2). In phase I (8 weeks), group 1 will complete the intervention and group 2 will proceed with TAU. In phase II (8 weeks), group 2 will complete the intervention and group 1 will continue with TAU until reaching an 8-week follow-up. TAU may consist of receiving psychotherapy, pharmacotherapy, or combined treatment. Data collection will be completed at baseline, 8 weeks (postintervention for group 1 and preintervention for group 2), and 16 weeks (follow-up for group 1, postintervention for group 2). The primary outcomes will include (1) current, residual, or chronic depression symptoms and (2) psychiatric distress. Secondary outcomes will include perceived stress and facets of mindfulness. The feasibility will be measured by assessing protocol adherence, retention, attendance, and engagement. Finally, the extent of mindfulness self-practice and executive functioning skills will be assessed as mediators of intervention outcomes. RESULTS: This study began screening and recruitment in December 2022. Data collection from the first cohort occurred in January 2023. By November 2023, a total of 30 participants were enrolled out of 224 who received screening. Data analysis began in February 2024, with an approximate publication of results by August 2024. Institutional review board approval took place on September 11, 2019. CONCLUSIONS: This trial will contribute to examining mindfulness-based interventions, delivered via the web, for improving current, residual, or chronic depression symptoms. It will (1) address the feasibility of MBCT delivered via the web; (2) contribute evidence regarding MBCT's efficacy in reducing depression symptoms and psychiatric distress; and (3) assess the impact of MBCT on several important secondary outcomes. Findings from this study will develop the understanding of the causal pathways between MBCT delivered via the web and depression symptoms further, elucidating the potential for future larger-scale designs.

Overreporting of adherence to hepatitis C direct-acting antiviral therapy and sustained virologic response among people who inject drugs in the HERO study.

BACKGROUND: Self-reported adherence to direct-acting antivirals (DAAs) to treat hepatitis C virus (HCV) among persons who inject drugs (PWID) is often an overreport of objectively measured adherence. The association of such overreporting with sustained virologic response (SVR) is understudied. This study among PWID aimed to determine a threshold of overreporting adherence that optimally predicts lower SVR rates, and to explore correlates of the optimal overreporting threshold. METHODS: This study analyzed per-protocol data of participants with adherence data (N = 493) from the HERO (Hepatitis C Real Options) study. Self-reported and objective adherence to a 12-week DAA regimen were measured using visual analogue scales and electronic blister packs, respectively. The difference (Δ) between self-reported and objectively measured adherence was calculated. We used the Youden index based on receiver operating characteristic (ROC) curve analysis to identify an optimal threshold of overreporting for predicting lower SVR rates. Factors associated with the optimal threshold of overreporting were identified by comparing baseline characteristics between participants at/above versus those below the threshold. RESULTS: The self-reported, objective, and Δ adherence averages were 95.1% (SD = 8.9), 75.9% (SD = 16.3), and 19.2% (SD = 15.2), respectively. The ≥ 25% overreporting threshold was determined to be optimal. The SVR rate was lower for ≥ 25% vs. < 25% overreporting (86.7% vs. 95.8%, p <.001). The factors associated with ≥ 25% Δ adherence were unemployment; higher number of days and times/day of injecting drugs; higher proportion of positive urine drug screening for amphetamine, methamphetamine, and oxycodone, and negative urine screening for THC (tetrahydrocannabinol)/cannabis. CONCLUSIONS: Self-reported DAA adherence was significantly greater than objectively measured adherence among PWID by 19.2%. Having ≥ 25% overreported adherence was associated with optimal prediction of lower SVR rates. PWID with risk factors for high overreporting may need to be more intensively managed to promote actual adherence.

Self-reported and measured adherence to hepatitis C direct-acting antiviral therapy and sustained virologic response among people who inject drugs: The HERO study.

BACKGROUND: Objective adherence measures, such as electronic blister pack (BP), for direct-acting antivirals (DAAs) for hepatitis C virus (HCV) treatment have high accuracy, but their use is limited in real practice settings. We examined the association of self-reported adherence using a visual analogue scale (VAS) with objective BP adherence and sustained virologic response (SVR) among people who inject drugs. METHODS: We conducted secondary analyses using a subset of participants (N = 493) from the per-protocol sample of the HERO study, a pragmatic randomized trial of HCV treatment interventions that used both VAS and BP to measure adherence to a 12-week sofosbuvir/velpatasvir DAA regimen. Multivariable mixed-effects regression models tested the association of self-report adherence level with longitudinal weekly objective adherence. Multivariable logistic regression tested the association of self-report adherence with SVR. RESULTS: The average VAS and BP adherences were 95.1 % (SD = 8.9 %) and 76.0 % (16.0 %), respectively, and the proportion of the participants achieving SVR was 92.9 %. The estimated adjusted mean objective adherence was significantly different (-16 %; 95 % CI: -22 %, -11 %, p < .001) between participants with 100 % and <80 % VAS adherence. The likelihood of SVR was significantly lower for those with <80 % VAS adherence [adjusted OR = 0.07; 95 % CI: 0.02, 0.24; p < .001] compared to those with 100 %. CONCLUSION: Self-reported adherence overestimated objective adherence. However, higher self-report adherence was significantly associated with higher objective adherence. Also, self-reported adherence ≥80 % was significantly associated with SVR. Thus, the self-report measure has utility as a monitoring tool for adherence during DAA treatment.

Effectiveness of Transitional Care Program among High-Risk Discharged Patients: A Quasi-Experimental Study on Saving Costs, Post-Discharge Readmissions and Emergency Department Visits.

Transitional care programs (TCPs), where hospital care team members repeatedly follow up with discharged patients, aim to reduce post-discharge hospital or emergency department (ED) utilization and healthcare costs. We examined the effectiveness of TCPs at reducing healthcare costs, hospital readmissions, and ED visits. Centers for Medicare and Medicaid Services Bundled Payments for Care Improvement (BPCI) program adjudicated claims files and electronic health records from Greenville Memorial Hospital, Greenville, SC, were accessed. Data on post-discharge 30- and 90-day ED visits and readmissions, total costs, and episodes with costs over BPCI target prices were extracted from November 2017 to July 2020 and compared between the "TCP-Graduates" (N = 85) and "Did Not Graduate" (DNG) (N = 1310) groups. As compared to the DNG group, the TCP-Graduates group had significantly fewer 30-day (7.1% vs. 14.9%, p = 0.046) and 90-day (15.5% vs. 26.3%, p = 0.025) readmissions, episodes with total costs over target prices (25.9% vs. 36.6%, p = 0.031), and lower total cost/episode (USD 22,439 vs. USD 28,633, p = 0.018), but differences in 30-day (9.4% vs. 11.2%, p = 0.607) and 90-day (20.0% vs. 21.9%, p = 0.680) ED visits were not significant. TCP was associated with reduced post-discharge hospital readmissions, total care costs, and episodes exceeding target prices. Further studies with rigorous designs and individual-level data should test these findings.

Reduction in Depressive Symptoms in People who Inject Drugs who Are Cured of Hepatitis C Virus Infection: The HERO Study.

Background: Depressive symptoms are prevalent among people who inject drugs (PWID) and people with hepatitis C virus (HCV). We examined changes in depressive symptoms among HCV-infected PWID following direct-acting antiviral treatments to evaluate whether these changes differed by history of depressive symptoms, substance use, or HCV treatment outcome. Methods: We conducted a secondary analysis of the HERO Study (NCT02824640), a pragmatic randomized clinical trial among PWID, to test the effectiveness of HCV care models. Depressive symptoms (primary outcome) were measured using the Patient Health Questionnaire (PHQ-9) at baseline, end of treatment (EOT), and at follow-up 12 and 24 weeks after EOT. Sustained virologic response (SVR) was defined as undetectable HCV RNA at ≥12 weeks following EOT. Baseline drug use was defined as having a positive urine screening test for amphetamine, methamphetamine, benzodiazepine, cocaine, cannabis, opiate, or oxycodone. Results: The sample (n = 498) was 72.3% male, 64.2% White, and on average 43.9 years old. In patients who achieved SVR (F(3432) = 4.58; P = .004) and those with drug use at baseline (F(3478) = 5.11; P < .01), PHQ-9 scores significantly declined over time, with scores lower at EOT and both follow-ups as compared with baseline. Mean PHQ-9 scores at EOT and follow-ups were significantly lower than at baseline, except for those with no depression or mild depression at baseline. Conclusions: This study showed that HCV treatment in PWID is associated with sustained declines in depression up to 24 weeks post-treatment among those who achieve SVR and that drug use does not interfere with improvement in depressive symptoms.

Meditation and Cognitive Outcomes: A Longitudinal Analysis Using Data From the Health and Retirement Study 2000-2016.

Objective: We aimed to assess the association between meditation practice and cognitive function over time among middle-aged and older adults. Method: We included Health and Retirement Study (HRS) participants assessed for meditation practice in the year 2000 as part of the HRS alternative medicine module (n = 1,160) and were followed up for outcomes over 2000-2016 period. We examined the association between meditation ≥ twice a week vs none/less frequent practice and changes in the outcomes of recall, global cognitive function, and quantitative reasoning using generalized linear regression models. Stratified analyses among persons with/without self-reported baseline depressive symptoms were conducted to assess the link between meditation and cognitive outcomes. Results: Among our full study sample, meditation ≥ twice a week was not significantly associated with total recall [ß; 95% CI: -0.97, 0.57; p = 0.61], global cognitive function [ß; 95% CI: -1.01, 1.12; p = 0.92], and quantitative reasoning [ß; 95% CI: -31.27, 8.32; p = 0.26]. However, among those who did not have self-reported depressive symptoms at baseline, meditation ≥ twice a week was associated with improvement in cognitive outcomes such as total recall [ß; 95% CI: 0.03, 0.18; p = 0.01] and global cognitive function [ß; 95% CI: 0.05, 0.40; p = 0.01] over time. Conclusions: Frequent meditation practice might have a protective effect on cognitive outcomes over time, but this protection could be limited to those without self-reported baseline depressive symptoms. Future studies could incorporate more precise meditation practice assessment, investigate the effect of meditation on cognitive outcomes over time, and include more rigorous study designs with randomized group assignment. Pre-registration: This study is not preregistered.

Outpatient Opioid Dispensing Patterns for SC Medicaid Children 1-36 Months Old.

OBJECTIVES: We sought to identify the most common diagnostic categories linked to dispensed opioid prescriptions among children 1-36 months old and changes in patterns over the years 2000 to 2017. METHODS: This study used South Carolina's Medicaid claims data of pediatric dispensed outpatient opioid prescriptions between 2000 and 2017. The major opioid-related diagnostic category (indication) for each prescription was identified using visit primary diagnoses and the Clinical Classification System (AHRQ-CCS) software. The variables of interest were the rate of opioid prescriptions per 1,000 visits for each diagnostic category and the relative percentage of opioid prescriptions assigned to each category compared to all categories. RESULTS: Six major diagnostic categories were identified; Diseases of the respiratory system (RESP), Congenital anomalies (CONG), Injury (INJURY), Diseases of the nervous system and sense organs (NEURO), Diseases of the digestive system (GI), and Diseases of the genitourinary system (GU). The overall rate of dispensed opioid prescriptions per category declined significantly for four diagnostic categories throughout the study period, RESP by 15.13, INJURY by 8.49, NEURO by 7.33, and GI by 5.93. Two categories increased during the same time, CONG (by 9.47) and GU (by 6.98). RESP was the most prevalent category linked to a dispensed opioid prescription within 2010-2012 (almost 25%) but CONG was the most prevalent by 2014 (17.77%). CONCLUSIONS FOR PRACTICE: Among Medicaid children 1-36 months old, annual dispensed opioid prescription rates declined for most major diagnostic categories (RESP, INJURY, NEURO, and GI). Future studies should explore alternatives to current opioid dispensing practices for GU and CONG cases.

California's Comprehensive Perinatal Services Program and birth outcomes.

Introduction: California's Medicaid (Medi-Cal) sponsors Comprehensive Perinatal Services Program (CPSP), a program with enhanced perinatal care for women (more education, nutritional supplements, and psychosocial counseling/support). Past evaluations of CPSP's effectiveness in birth outcomes were limited to pilot programs and yielded mixed results. Methods: We used 2012-2016 California's statewide data about singleton live births with any receipt of prenatal care (N = 2,385,811) to examine whether Medi-Cal with CPSP enrollment was associated with lower odds of preterm birth (PTB), spontaneous PTB, and low birthweight (LBW) than non-CPSP births. With three binary variables of PTB, spontaneous PTB, and LBW as the response variables, three multilevel logistic models were used to compare the outcomes of participants enrolled in Medi-Cal with CPSP against those with private insurance, adjusting for maternal factors and county-level covariates. Results: Logistic models showed that participants enrolled to Medi-Cal with CPSP [n (%) = 89,009 (3.7)] had lower odds of PTB, spontaneous PTB and LBW, respectively, as compared with those with private insurance [n (%) = 1,133,140 (47.2)]. Within the Medi-Cal sub-population, the CPSP enrollment was associated with lower odds of PTB, SPTB and LBW than Medicaid beneficiaries without CPSP [n (%) = 967,094 (40.3)]. Discussion: With statewide data, these findings revealed a robust link between CPSP enrollment and better birth outcomes. Expanding access to comprehensive prenatal services could be an important strategy to improve birth outcomes.

Economic Evaluations of Mindfulness-Based Interventions: a Systematic Review.

Objectives: This study includes a systematic review of cost-effectiveness analyses (CEAs) and cost-benefit analyses (CBAs) of mindfulness-based interventions (MBIs). Methods: A literature search was conducted using PubMed, Web of Science, JSTOR, and CINAHL for studies published between January 1985 and September 2021, including an original cost-related evaluation of an MBI. A qualitative assessment of bias was performed using the Drummond checklist. Results: Twenty-eight mindfulness-based intervention studies (18 CEAs and 10 CBAs) were included in this review. Mindfulness-based stress reduction (MBSR) was less costly and more effective when compared with the usual care of cognitive behavioral therapy among patients with chronic lower back pain, fibromyalgia, and breast cancer. MBSR among patients with various physical/mental conditions was associated with reductions in healthcare costs. Mindfulness-based cognitive therapy (MBCT) was also less costly and more effective than the comparison group among patients with depression, medically unexplained symptoms, and multiple sclerosis. MBCT's cost-effectiveness advantage was also identified among breast cancer patients with persistent pain, non-depressed adults with a history of major depressive disorder episodes, adults diagnosed with ADHD, and all cancer patients. From a societal perspective, the cost-saving property of mindfulness training was evident when used as the treatment of aggressive behaviors among persons with intellectual/developmental disabilities in mental health facilities. Conclusions: Based on this review, more standardized MBI protocols such as MBSR and MBCT compare favorably with usual care in terms of health outcomes and cost-effectiveness. Other MBIs may result in cost savings from both healthcare and societal perspectives among high-risk patient populations.

Dispensed Opioid Prescription Patterns, by Racial/Ethnic Groups, Among South Carolina Medicaid-Funded Children Experiencing Limb Fracture Injuries.

OBJECTIVE: To examine dispensed opioid prescription patterns for limb fractures across racial/ethnic groups in a pediatric population. METHODS: We used South Carolina's Medicaid claims data 2000 to 2018 for pediatric limb fracture cases (under age 19) discharged from the emergency department. The key independent variable was the child's race/ethnicity. The outcomes were: 1) whether the patient had a dispensed opioid prescription; and 2) whether dispensed opioid supply was longer than 5 days among cases with any dispensed opioid prescriptions. Logistic regression models were used to test the association between race/ethnicity and the outcomes. Covariates included age-at-service, gender, service year, and having multiple fracture injuries. RESULTS: Compared with non-Hispanic White cases (NHW), the odds of receiving dispensed opioid prescriptions were lower for cases of non-Hispanic Black (NHB) (OR = 0.73; 95% confidence interval [CI]: 0.71, 0.75), Asian (OR = 0.69; CI: 0.53, 0.90), Other/Unknown (OR = 0.86; CI: 0.80, 0.92), and Hispanic (OR = 0.84; CI: 0.79, 0.90) race/ethnicity. The odds of receiving >5 days of dispensed opioid prescription supply did not differ significantly among race/ethnic categories. CONCLUSIONS: Our study confirms previous findings that as compared to NHW, the NHB children were less likely to receive dispensed opioid prescriptions. Also, it reveals that the different minority race/ethnic groups are not homogenous in their likelihoods of receiving dispensed opioid prescriptions after a limb fracture compared to NHW, findings underreported in previous studies. Children in the Other/Unknown race/ethnicity category have prescribing patterns different from those of other minority race/ethnic groups and should be analyzed separately.

A feasibility study on low-dose mindfulness-based stress reduction intervention among prediabetes and diabetes patients.

OBJECTIVES: To investigate the feasibility of delivering a low-dose mindfulness-based stress reduction (MBSR) intervention among prediabetes/diabetes patients in a clinical setting. DESIGN AND SETTING: This was a single-arm, mixed methods, feasibility study among prediabetes/diabetes patients at a healthcare center in United States. INTERVENTION: The low-dose MBSR intervention was delivered in group format over 4 waves and each wave comprised 8-10 h of 8 sessions over 6-8 weeks. MAIN OUTCOME MEASURES: We evaluated recruitment, adherence, and attrition rates, participants' satisfaction, motivation and barriers of low-dose MBSR. Psychological, behavioral, and physical measures were compared between pre- and post-intervention. RESULTS: We enrolled 19 participants of 34 eligible individuals with a recruitment rate of 55.9%. Among 19 enrolled participants, 4 dropped out after baseline data collection and did not attend any session and 1 attended one session but did not finish post-intervention data collection, resulting in an attrition rate of 26.3%. Among 15 participants attending at least one session, 46.7% attended all sessions and 80.0% attended at least 5 sessions. Qualitative analysis among 11 participants indicated that 90.9% had positive overall experience with the intervention. Compared to pre-intervention, there was a significant reduction in depression score (mean reduction = 5.04, SD = 7.66, p = 0.02), a higher proportion of engaging in flexibility exercises (42.86% vs. 85.71%, p = 0.01) and a lower level of glycosylated hemoglobin (HbA1c) (mean reduction = 1.43%, SD = 2.54%, p = 0.03) at post-intervention. CONCLUSIONS: Delivering a low-dose MBSR intervention to prediabetes/diabetes patients in a primary care setting is feasible. Future studies with randomized controlled design and larger sample are warranted.

A qualitative study on participants' experiences with a community-based mindful walking intervention and mobile device activity measurement.

BACKGROUND: Mindful walking (MW) interventions employ mindfulness training combined with physical activity. Wearable mobile devices have been increasingly used to measure outcomes of physical activity interventions. The purpose of this study was to understand MW participants' attitudes towards MW and the use of mobile devices in health promotion interventions, including barriers and facilitators of intervention engagement and adherence. Few qualitative studies have documented participant experience with these two types of interventions. METHOD: The pilot study involved a randomized MW intervention including 38 participants with self-reported inadequate physical activity. Half of them were randomized to receive MW intervention plus a FitBit device and the other received the FitBit device only. We used a qualitative thematic analysis of the narrative data collected through open-ended survey questions at three time points. Participants in the MW intervention were asked to describe their experiences with MW, while all participants were asked to describe their experience with wearing the FitBit to track their step counts. RESULTS: Participants reported a broad range of perceived benefits and challenges related to adopting the MW intervention and using the mobile device. Participants were generally willing to try to adopt the recommended MW practice and to see value of MW in increasing physical activity and improving overall health. Participants reported using a variety of additional device features beyond goal setting and step counts, indicating using the devices may have been effective in providing additional motivation for participants in meeting physical activity goals in both the control and intervention groups. While most of the feedback about MW (in the intervention group) and the device (all participants) was overwhelmingly positive, a minority of participants reported barriers such as lack of patience with meditation and discomfort with wearing the device. CONCLUSION: Most participants in the MW intervention see the health benefits of this program and most participants using the wearable physical activity tracking device reported the motivational benefits of this device. Issues with the MW intervention (e.g., lack of patience) and the wearable device (e.g., discomfort with wearing) need to be addressed in future interventions.

Study protocol for a randomized controlled trial of mindfulness-based relapse prevention for opioid use disorders.

The opioid misuse epidemic has reached a crisis level in the United States. Though mindfulness-based relapse prevention (MBRP) has been shown as effective in treating substance use disorders, there is limited research on its application to opioid use disorders specifically, and there is a need to understand the underlying mechanisms. This paper outlines a protocol for a randomized controlled trial of MBRP for opioid use disorders. MBRP is a group aftercare program that integrates mindfulness skills training with cognitive-behavioral relapse prevention strategies. We will recruit 240 participants who have completed opioid use disorder treatment, and randomize them to an 8-week MBRP group intervention or treatment as usual (TAU) control group. The TAU control group will complete the intervention after 8 weeks. Assessments will take place at baseline, 8 weeks, and 16 weeks. The primary outcome is frequency of opioid use. The secondary outcomes include craving and withdrawal symptoms, time to first opioid use, adherence to medication-assisted treatment plans, perceived stress, quality of life, posttraumatic stress symptoms, and chronic pain. We will also examine the following potential moderators and correlates of intervention outcomes: comorbid diagnoses, life events history, and MBRP intervention adherence. In addition, we will examine the following mediators of intervention outcome: mindfulness skills, emotion regulation skills, executive functioning skills, savoring, and positive and negative affect. This study will contribute to the evidence base regarding MBRP's efficacy in reducing opioid use, as well as contribute to the understanding of the causal mechanisms and factors that modify treatment outcome for MBRP for substance use disorders.

Perceptions about mindfulness-based interventions among individuals recovering from opioid and alcohol use disorders: Findings from focus groups.

OBJECTIVES: Mindfulness-based interventions (MBIs) have been used as an intervention to support recovery from alcohol use disorder (AUD) and opioid use disorder (OUD). We sought to identify attitudes and experiences toward standardized MBIs among individuals recovering from these substance abuse disorders (SUD) through a qualitative approach. DESIGN: We conducted three 60-minute focus groups among people with history of SUD (6-months to 3 years in recovery): two groups with those with alcohol use disorder (AUD) history and one with individuals with history of opioid use disorder (OUD). Each group had eight participants. RESULTS: Most participants of the OUD focus group had tried some variations on mindfulness training or meditation-like therapies during treatment. Participants expressed perceived benefits for MBIs' non-pharmacological property, while expressing concerns related to perceived barriers of cost, scheduling conflicts with work and child/family care needs, and possible lack of provider empathy. Gift cards and other rewards were recognized as useful participation and retention incentives for completing the described program; the training itself was perceived as an "incentive" if able to deliver significant benefits related to supporting continued recovery from SUD. An overarching theme across all groups was that participants reported their own altruistic behavior and social connectedness as important motivators to help them maintain recovery. CONCLUSION: The importance of perceived provider empathy and the patient's social connectedness in SUD interventions was underscored as incentives for participation and retention, providing valuable information for the implementation of MBIs among patients recovering from SUD.

A pilot study of mindful walking training on physical activity and health outcomes among adults with inadequate activity.

INTRODUCTION: Mindful walking is a meditation practice that combines physical activity and mindfulness practice. Some mindful walking interventions expect four weeks of attendance (as compared with the traditional 8-week models of mindfulness-based interventions, or MBIs), a practice that could make MBIs more accessible to working-age adults. This study examined whether a 4-week mindful walking intervention increased physical activity and improved mental health outcomes. METHODS: We conducted a randomized experiment among adults with inadequate physical activity (N = 38), whereby the intervention group received a four-week, one-hour-per-week mindful walking intervention and the control group received instructions to increase physical activity. Everyone in both groups received a wrist-worn step count device as participation incentive. Physical activity (as measured by the Rapid Assessment of Physical Activity questionnaire, RAPA) and other health outcomes were assessed with online surveys at baseline (T1), post-intervention (T2), and one month after the intervention (T3). Those mental health outcomes included perceived stress (Perceived Stress Scale), depression (Brief Edinburgh Depression Scale), and Mental Health Inventory (MHI). The primary outcome of device-measured step count was recorded at T1 and T2. Independent two-sample t-tests were used to compare the primary outcomes at T1. Generalized linear mixed models (GLMM) with a random intercept for each subject were used to compare the two groups on the primary outcomes at all time points. The independent variables in the model included a binary variable for group assignment (intervention vs. control), a 3-level categorical variable for time, and their interaction. Age, gender and race/ethnicity are used as covariates in the model. Estimated changes (either differences or ratios between outcomes at time points T1 and T2/T3) are reported to assess change within groups. RESULTS: Both groups exhibited significant improvements in the RAPA measures of physical activity and depression. However, between-group differences were not statistically significant. There was no within-group or between-group difference on device-measured step count, though both groups yielded an average daily step count close to the recommended level of 8,000 steps per day for older adults. The intervention group exhibited a significant reduction in perceived stress, and this reduction was significantly greater than that of the control group at T2 (p = .025) although the difference was insignificant at T3. No significant difference in MHI was found. DISCUSSION: While these adults with inadequate physical activity increased their physical activity, no significant between-group differences in physical activity were identified. Potential reasons for the lack of significant findings could be due to the ceiling effect (the step count device for everyone in both groups might have encouraged more activity in both groups), limited sample size and low-dose 4-week intervention used in this study. On the other hand, it is encouraging to see that this low-dose, short-duration 4-week intervention (as compared with those popular 8-week MBIs) achieved significantly greater stress reduction among the intervention group than among the control group, even though the between-group difference at one-month follow-up was statistically insignificant. Further studies with larger sample sizes and longer follow-up are needed to assess the possible benefits of these short-duration mindful walking interventions.

An Investigation of the Information Sought by Caregivers of Alzheimer's Patients on Online Peer Support Groups.

Caregivers of Alzheimer's patients find respite in online communities for solutions and emotional support. This study aims to understand the characteristics of information caregivers of Alzheimer's patients are searching for and the kind of support they receive through Internet-based peer support communities. Using a Web crawler written in Python Web programming language, we retrieved publicly available 2,500 random posts and their respective solutions from April 2012 to October 2016 on the solutions category of the Caregiver's Forum on ALZConnected.org . A content analysis was conducted on these randomly selected posts and 4,219 responses to those posts based on a classification system were derived from initial analyses of 750 posts and related responses. The results showed most posts (26%) related to queries about Alzheimer's symptoms, and the highest percentage of responses (45.56%) pertained to caregiver well-being. The LIWC analyses generated an average tone rating of 27.27 for the posts, implying a negative tone and 65.17 for their responses, implying a slightly positive tone. The ALZConnected.org Web site has the potential of being an emotionally supportive tool for caregivers; however, a more user-friendly interface is required to accommodate the needs of most caregivers and their technological skills. Solutions offered on the peer support groups are often subjective opinions of other caregivers and should not be considered professional or comprehensive; further research on educating caregivers using online forums is necessary.
