Feasibility, acceptability, and efficacy of a positive emotion regulation intervention to promote resilience for healthcare workers during the COVID-19 pandemic: A randomized controlled trial.

INTRODUCTION: Burnout poses a substantial, ongoing threat to healthcare worker (HCW) wellbeing and to the delivery of safe, quality healthcare. While systemic and organization-level changes in healthcare are critically important, HCWs also need individual-level skills to promote resilience. The objective of this trial is to test feasibility, acceptability, and efficacy of PARK, an online self-guided positive affect regulation intervention, in a sample of healthcare workers during the COVID-19 pandemic. DESIGN AND METHODS: In the context of the unprecedented rise in burnout during the COVID-19 pandemic, we conducted a randomized waitlist-controlled trial of the Positive Affect Regulation sKills (PARK) program-a five-week, online, self-guided coping skills intervention nested within an ongoing cohort of HCWs. N = 554 healthcare workers were randomly assigned to receive the intervention immediately or to receive the intervention after approximately 12 weeks. Outcomes included change in burnout, emotional wellbeing (positive affect, meaning and purpose, depression, anxiety) and sleep over approximately 12 weeks. Analyses included mixed-effects linear regression models comparing change over time in outcomes between intervention and control conditions. RESULTS: One third (n = 554) of the participants in the cohort of HCWs consented to participate and enrolled in PARK in April 2022. Compared to those who did not enroll, participants in the trial reported higher burnout, poorer emotional wellbeing, and poorer sleep at baseline (April, 2022; all ps < .05). Intent-to-treat analyses showed that participants randomly assigned to the intervention immediately (PARK-Now) improved significantly on anxiety (within-group change on PROMIS T-score = -0.63; p = .003) whereas those in the waitlist (PARK-Later) did not (within group T-score change 0.04, p = 0.90). The between-group difference in change, however, was not statistically significant (B = -0.67 p = 0.10). None of the other wellbeing outcomes changed significantly in the intervention group compared to the waitlist. Additional as-treated analyses indicated that those participants who completed all 5 of the weekly online lessons (N = 52; 9.4%) improved significantly more on the primary outcome of positive affect compared to those who enrolled in PARK but completed zero lessons (n = 237; 42.8%; B = 2.85; p = .0001). CONCLUSIONS: Online self-guided coping skills interventions like PARK can be effective in targeted samples and future work will focus on adaptations to increase engagement and tailor PARK for HCWs who could most benefit.

Developing Social Enhancements for a Web-Based, Positive Emotion Intervention for Alzheimer Disease Caregivers: Qualitative Focus Group and Interview Study.

BACKGROUND: Alzheimer disease is a degenerative neurological condition that requires long-term care. The cost of these responsibilities is often borne by informal caregivers, who experience an elevated risk of negative physical and psychological outcomes. Previously, we designed a positive emotion regulation intervention that was shown to improve well-being among dementia caregivers when delivered through one-on-one videoconferencing lessons with a trained facilitator. However, the format required significant resources in terms of logistics and facilitator time. To broaden the reach of the intervention, we aimed to develop the Social Augmentation of Self-Guided Electronic Delivery of the Life Enhancing Activities for Family Caregivers (SAGE LEAF) program, an iteration of the intervention in a self-guided, web-based format with enhanced opportunities for social connection. OBJECTIVE: The aim of this study was to gather feedback to inform the design of social features for the SAGE LEAF intervention. In the absence of a facilitator, our goal with the self-guided SAGE LEAF intervention was to integrate various social features (eg, discussion board, automated support, and profiles) to maximize engagement among participants. METHODS: Qualitative data were collected from 26 individuals through (1) interviews with participants who completed a previous version of the intervention via videoconferencing with a facilitator, (2) focus groups with dementia caregivers who had not previously experienced the intervention, and (3) focus groups with Alzheimer disease clinical care providers. We conducted a qualitative thematic analysis to identify which social features would be the most helpful and how they could be implemented in a way that would be best received by caregivers. RESULTS: Interview and focus group feedback indicated that participants generally liked the potential features suggested, including the discussion boards, multimedia content, and informational support. They had valuable suggestions for optimal implementation. For example, participants liked the idea of a buddy system where they would be matched up with another caregiver for the duration of the study. However, they expressed concern about differing expectations among caregivers and the possibility of matched caregivers not getting along. Participants also expressed interest in giving caregivers access to a podcast on the skills, which would allow them to review additional content when they wished. CONCLUSIONS: Taken together, the discussions with caregivers and providers offered unique insights into the types of social features that may be integrated into the SAGE LEAF intervention, as well as implementation suggestions to improve the acceptability of the features among caregivers. These insights will allow us to design social features for the intervention that are optimally engaging and helpful for caregivers.

Acceptability and Feasibility of a Socially Enhanced, Self-Guided, Positive Emotion Regulation Intervention for Caregivers of Individuals With Dementia: Pilot Intervention Study.

BACKGROUND: The responsibilities of being a primary caregiver for a loved one with dementia can produce significant stress for the caregiver, leading to deleterious outcomes for the caregiver's physical and psychological health. Hence, researchers are developing eHealth interventions to provide support for caregivers. Members of our research team previously developed and tested a positive emotion regulation intervention that we delivered through videoconferencing, in which caregiver participants would meet one-on-one with a trained facilitator. Although proven effective, such delivery methods have limited scalability because they require significant resources in terms of cost and direct contact hours. OBJECTIVE: This study aimed to conduct a pilot test of a socially enhanced, self-guided version of the positive emotion regulation intervention, Social Augmentation of Self-Guided Electronic Delivery of the Life Enhancing Activities for Family Caregivers (SAGE LEAF). Studies have shown that social presence or the perception of others in a virtual space is associated with enhanced learning and user satisfaction. Hence, the intervention leverages various social features (eg, discussion boards, podcasts, videos, user profiles, and social notifications) to foster a sense of social presence among participants and study team members. METHODS: Usability, usefulness, feasibility, and acceptability data were collected from a pilot test in which participants (N=15) were given full access to the SAGE LEAF intervention over 6 weeks and completed preintervention and postintervention assessments (10/15, 67%). Preliminary outcome measures were also collected, with an understanding that no conclusions about efficacy could be made, because our pilot study did not have a control group and was not sufficiently powered. RESULTS: The results suggest that SAGE LEAF is feasible, with participants viewing an average of 72% (SD 42%) of the total available intervention web pages. In addition, acceptability was found to be good, as demonstrated by participants' willingness to recommend the SAGE LEAF program to a friend or other caregiver. Applying Pearson correlational analyses, we found moderate, positive correlation between social presence scores and participants' willingness to recommend the program to others (r9=0.672; P=.03). We also found positive correlation between social presence scores and participants' perceptions about the overall usefulness of the intervention (r9=0.773; P=.009). This suggests that participants' sense of social presence may be important for the feasibility and acceptability of the program. CONCLUSIONS: In this pilot study, the SAGE LEAF intervention demonstrates potential for broad dissemination for dementia caregivers. We aim to incorporate participant feedback about how the social features may be improved in future iterations to enhance usability and to further bolster a sense of social connection among participants and study staff members. Next steps include partnering with dementia clinics and other caregiver-serving organizations across the United States to conduct a randomized controlled trial to evaluate the effectiveness of the intervention.

Facilitator Contact, Discussion Boards, and Virtual Badges as Adherence Enhancements to a Web-Based, Self-guided, Positive Psychological Intervention for Depression: Randomized Controlled Trial.

BACKGROUND: Adherence to self-guided interventions tends to be very low, especially in people with depression. Prior studies have demonstrated that enhancements may increase adherence, but little is known about the efficacy of various enhancements in comparison to, or in combination with, one another. OBJECTIVE: The aim of our study is to test whether 3 enhancements-facilitator contact (FC), an online discussion board, and virtual badges (VB)-alone, or in combination, improve adherence to a self-guided, web-based intervention for depression. We also examined whether age, gender, race, ethnicity, comfort with technology, or baseline depression predicted adherence or moderated the effects that each enhancement had on adherence. METHODS: Participants were recruited through web-based sources and, after completing at least 4 out of 7 daily emotion reports, were sequentially assigned to 1 of 9 conditions-the intervention alone; the intervention plus 1, 2, or all 3 enhancements; or an emotion reporting control condition. The intervention was a positive psychological program consisting of 8 skills that specifically targeted positive emotions, and it was delivered over 5 weeks in a self-guided, web-based format. We operationalized adherence as the number of skills accessed. RESULTS: A total of 602 participants were enrolled in this study. Participants accessed, on average, 5.61 (SD 2.76) of 8 skills. The total number of enhancements participants received (0-3) did not predict the number of skills accessed. Participants who were assigned to the VB+FC condition accessed significantly more skills than those in the intervention only conditions. Furthermore, participants in arms that received the combination of both the VB and FC enhancements (VB+FC and VB+FC+online discussion board) accessed a greater number of skills relative to the number of skills accessed by participants who received either VB or FC without the other. Moderation analyses revealed that the receipt of VB (vs no VB) predicted higher adherence among participants with moderately severe depression at baseline. CONCLUSIONS: The results suggested that the VB+FC combination significantly increased the number of skills accessed in a self-guided, web-based intervention for elevated depression. We have provided suggestions for refinements to these enhancements, which may further improve adherence.

Intervention Enhancement Strategies Among Adults With Type 2 Diabetes in a Very Low-Carbohydrate Web-Based Program: Evaluating the Impact With a Randomized Trial.

BACKGROUND: Adults with type 2 diabetes may experience health benefits, including glycemic control and weight loss, from following a very low-carbohydrate, ketogenic (VLC) diet. However, it is unclear which ancillary strategies may enhance these effects. OBJECTIVE: This pilot study aims to estimate the effect sizes of 3 intervention enhancement strategies (text messages, gifts, and breath vs urine ketone self-monitoring) that may improve outcomes of a 12-month web-based ad libitum VLC diet and lifestyle intervention for adults with type 2 diabetes. The primary intervention also included other components to improve adherence and well-being, including positive affect and mindfulness as well as coaching. METHODS: Overweight or obese adults (n=44; BMI 25-45 kg/m2) with type 2 diabetes (glycated hemoglobin [HbA1c] ≥6.5%), who had been prescribed either no glucose-lowering medications or metformin alone, participated in a 12-month web-based intervention. Using a 2×2×2 randomized factorial design, we compared 3 enhancement strategies: (1) near-daily text messages about the intervention's recommended behaviors (texts n=22 vs no texts n=22), (2) mailed gifts of diet-relevant foods and cookbooks (6 rounds of mailed gifts n=21 vs no gifts n=23), and (3) urine- or breath-based ketone self-monitoring (urine n=21 vs breath n=23). We assessed HbA1c and weight at baseline and at 4, 8, and 12 months. We evaluated whether each strategy exerted a differential impact on HbA1c and weight at 12 months against an a priori threshold of Cohen d of 0.5 or greater. RESULTS: We retained 73% (32/44) of the participants at 12 months. The intervention, across all conditions, led to improvements in glucose control and reductions in body weight at the 12-month follow-up. In intent-to-treat (ITT) analyses, the mean HbA1c reduction was 1.0% (SD 1.6) and the mean weight reduction was 5.3% (SD 6.0), whereas among study completers, these reductions were 1.2% (SD 1.7) and 6.3% (SD 6.4), respectively, all with a P value of less than .001. In ITT analyses, no enhancement strategy met the effect size threshold. Considering only study completers, 2 strategies showed a differential effect size of at least a d value of 0.5 or greater. CONCLUSIONS: Text messages, gifts of food and cookbooks, and urine-based ketone self-monitoring may potentially enhance the glycemic or weight loss benefits of a web-based VLC diet and lifestyle intervention for individuals with type 2 diabetes. Future research could investigate other enhancement strategies to help create even more effective solutions for the treatment of type 2 diabetes.

Well-being interventions for individuals with diabetes: A systematic review.

In patients with diabetes, psychological well-being constructs (e.g., optimism, positive affect) have been associated with superior medical outcomes, including better glucose control and lower mortality rates. Well-being interventions may be well-suited to individuals with diabetes, as they are simple to deliver, broadly applicable across a range of psychological distress, and may help increase self-efficacy and motivation for diabetes self-care. This systematic review, completed using PRISMA guidelines, examined peer-reviewed studies indexed in PubMed, PsycINFO, and/or Scopus between database inception and October 2017 that investigated the effects of well-being interventions (e.g., positive psychology interventions, mindfulness-based interventions, resilience-based interventions) on psychological and physical health outcomes in individuals with Type 1 or Type 2 diabetes. The search yielded 34 articles (N = 1635 participants), with substantial variability in intervention type, measures used, and outcomes studied; the majority found the intervention to provide benefit. Overall, results indicate that a range of well-being interventions appear to have promise in improving health outcomes in this population, but the literature does not yet provide definitive data about which specific interventions are most effective. The variability in interventions and outcomes points to a need for further rigorous, controlled, and well-powered studies of specific interventions, with well-accepted, clinically relevant outcome measures.

Positive and Negative Self-Conscious Emotion and Transmission Risk Following HIV Diagnosis.

While negative emotions are associated with risk behaviors and risk avoidance among people with HIV, emerging evidence indicates that negative self-conscious emotions, those evoked by self-reflection or self-evaluation (e.g., shame, guilt, and embarrassment), may differentially influence health-risk behaviors by producing avoidance or, conversely, pro-social behaviors. Positive emotions are associated with beneficial health behaviors, and may account for inconsistent findings related to negative self-conscious emotions. Using multinomial logistic regression, we tested whether positive emotion moderated the relationships between negative emotion and negative self-conscious emotions and level of condomless sex risk: (1) seroconcordant; (2) serodiscordant with undetectable viral load; and (3) serodiscordant with detectable viral load [potentially amplified transmission (PAT)] among people recently diagnosed with HIV (n = 276). While positive emotion did not moderate the relationship between negative emotion and condomless sex, it did moderate the relationship between negative self-conscious emotion and PAT (AOR = 0.60; 95% CI 0.41, 0.87); high negative self-conscious and high positive emotion were associated with lower PAT risk. Acknowledgment of both positive and negative self-conscious emotion may reduce transmission risk behavior among people with HIV.

Positive Affect and Health Behaviors Across 5 Years in Patients With Coronary Heart Disease: The Heart and Soul Study.

OBJECTIVES: Positive psychological states are linked to superior health and longevity, possibly due to behavioral factors. We evaluated cross-sectional and 5-year associations between positive affect and health behaviors in patients with coronary heart disease (CHD). METHODS: Outpatients with CHD reported positive affect, physical activity, sleep quality, medication adherence, cigarette smoking, and alcohol use at baseline (n = 1022) and 5 years later (n = 662). Covariates in regression analyses included demographics, cardiac disease severity, and depressive symptoms. RESULTS: At baseline, higher positive affect (per 1 standard deviation) was associated with better health behaviors: physical activity (odds ratio [OR] = 1.52, 95% 95% confidence interval [CI] = 1.30-1.77, p < .001), sleep quality (OR = 1.24, 95% CI = 1.04-1.48, p = .015), medication adherence (OR = 1.46, 95% CI = 1.12-1.90, p = .005), and nonsmoking (OR = 1.29, 95% CI = 1.06-1.57, p = .012), but was unrelated to alcohol use. Baseline positive affect did not predict health behaviors at follow-up, accounting for baseline behaviors. However, increases in positive affect across 5 years co-occurred with improvements in physical activity (B = 0.023, standard error [SE] = 0.008, p = .002), sleep quality (B = 0.011, SE = 0.005, p = .039), and medication adherence (B = 0.014, SE = 0.004, p < .001), but not smoking status (OR = 1.07, 95% CI = 0.73-1.55, p = .74). CONCLUSIONS: Positive affect was associated with health behaviors among patients with CHD. Efforts to sustain or enhance positive affect may be promising for promoting better health behaviors.

Life enhancing activities for family caregivers of people with frontotemporal dementia.

Aberrant psychological and behavioral symptoms are common in patients with dementia. These symptoms have negative consequences for family caregivers, causing stress and burden. Frontotemporal dementia (FTD) symptoms cause more pronounced stress and burden on caregivers than those associated with Alzheimer dementia. In this randomized, attention control pilot study, we delivered 5-weekly, one-on-one, positive affect intervention sessions to family caregivers of people with FTD. The program, Life Enhancing Activities for Family Caregivers: LEAF was conducted in-person or by videoconference with caregivers across the United States. Measures of affect, caregiver mood, stress, distress, and caregiver burden were assessed at baseline, end of sessions, and 1 month after completion. Twenty-four caregivers (12 intervention and 12 attention control) participated. At the end of the intervention, scores on positive affect, negative affect, burden, and stress all improved in the intervention compared with the control group. These scores continued to show improvement at the assessment done 1 month after intervention. Subjects were receptive to the skills and the delivery methods. The positive emotion skill-building intervention proved feasible especially in the internet videoconference delivery format. The intervention promoted positive affect and improved psychological outcomes for family caregivers of people with FTD.

Positive affect promotes engagement in care after HIV diagnosis.

OBJECTIVE: Revised Stress and Coping Theory proposes that positive affect serves adaptive functions, and its beneficial effects are heightened during stressful periods. This study examined the prospective relationship between positive affect and engagement in care during the 18 months after a HIV seropositive diagnosis. METHODS: The Coping, HIV, and Affect Interview (CHAI) cohort study enrolled 153 individuals who had recently received a HIV seropositive diagnosis. Using logistic and linear regression, baseline positive affect was examined as a predictor of linkage to HIV care, antiretroviral therapy (ART) persistence (i.e., starting ART and remaining on it during subsequent follow-up assessments), and mean log10 HIV viral load over follow-up. RESULTS: After controlling for education, T-helper (CD4+) count, HIV viral load, and negative affect, higher baseline positive affect independently predicted increased odds of linkage to HIV care at 3 months postdiagnosis (adjusted OR [AOR] = 1.10; 95% CI = 1.01-1.21) and ART persistence over the 18-month follow-up period (AOR = 1.08; 95% CI = 1.01-1.16). Positive affect was not directly associated with lower mean HIV viral load over follow-up. However, one standard deviation higher positive affect indirectly predicted 6.7% lower HIV viral load via greater odds of ART persistence (ßindirect = -0.18, p < .05). CONCLUSIONS: Greater positive affect predicts linkage to HIV care and ART persistence. ART persistence, in turn, is associated with lower HIV viral load. Clinical research is needed to examine whether interventions designed to enhance positive affect can boost the effectiveness of HIV treatment as prevention.

Illness appraisals and depression in the first year after HIV diagnosis.

Illness appraisals provide important context to help understand the way individuals cope with chronic illness. In the present study, a qualitative approach to the analysis of HIV diagnosis experience narratives in a sample of 100 people newly diagnosed with HIV revealed five groups that differed in their initial illness appraisals: HIV as Chronic Illness, Concern about Dying, Stigmatization, Threat to Identity, and Other Threats Overshadow HIV. When compared on quantitatively measured depressive mood, the groups differed on level and trajectory over the course of the first year post-diagnosis. Although the experience of living with HIV has changed significantly with the advent of effective Antiretroviral Therapies (ART), there were a number of similarities between the appraisals of this group of participants who were diagnosed post ART and groups who were diagnosed before ART became widely available. Posttest counselors and other HIV service providers should take individual differences in illness appraisals into account in order to help newly HIV-positive clients manage their healthcare and cope adaptively with their diagnosis.

Positive affect and processes of recovery among treatment-seeking methamphetamine users.

BACKGROUND: Revised Stress and Coping Theory proposes that positive affect serves adaptive functions, independent of negative affect. However, scant research has examined whether, how, and under what circumstances positive affect is associated with decreased substance use. METHODS: Eighty-eight methamphetamine-using men who have sex with men (MSM) completed the baseline assessment for substance abuse treatment outcome study which included measures of positive and negative affect, cognitive-behavioral change processes (i.e., approach-oriented coping, self-efficacy for managing methamphetamine triggers, and abstinence-related action tendencies), abstinence-specific social support, and self-reported substance use. Participants also provided a urine sample for toxicology screening. RESULTS: After controlling for demographic characteristics and negative affect, higher positive affect was independently associated with greater approach-oriented coping, abstinence-related action tendencies, and abstinence-specific social support. Positive affect was also independently associated with greater self-efficacy for managing methamphetamine triggers, but only at lower levels of negative affect. Through these cognitive-behavioral and social pathways, positive affect was indirectly associated with lower frequency of stimulant use in the past 30 days, lower odds of reporting stimulant use two or more days in a row, and lower odds of providing a urine sample that was reactive for stimulant metabolites. On the other hand, negative affect was not indirectly associated with any measure of stimulant use. CONCLUSIONS: Clinical research is needed to examine the pathways whereby positive affect may predict better substance abuse treatment outcomes.

Positive Affect in the Midst of Distress: Implications for Role Functioning.

Stress has been shown to deplete the self-regulation resources hypothesized to facilitate effective role functioning. However, recent research suggests that positive affect may help to replenish these vital self-regulation resources. Based on revised Stress and Coping theory and the Broaden-and-Build theory of positive emotion, three studies provide evidence of the potential adaptive function of positive affect in the performance of roles for participants experiencing stress. Participants were students (Study 1), caregivers of ill children (Study 2), and individuals recently diagnosed with HIV (Study 3). In cross sectional analyses, using role functioning as an indicator of self-regulation performance, we found that positive affect was significantly correlated with better self regulation performance, independent of the effects of negative affect. The effects were not as strong longitudinally, however, and there was little evidence of a reciprocal association between increases in positive affect and improvements in role functioning over time. The results provide some modest support for hypotheses stemming from the Broaden and Build model of positive emotion and revised Stress and Coping theory, both of which argue for unique adaptive functions of positive affect under stressful conditions.

Disclosure and nondisclosure among people newly diagnosed with HIV: an analysis from a stress and coping perspective.

Disclosing HIV status to friends, family, and sex partners is often stressful. However, HIV disclosure has been associated with improved physical health, psychological well-being, and improved health behaviors. The aim of this study was to address some of the gaps in the literature regarding the disclosure process by conducting a mixed-methods study of disclosure in people newly diagnosed with HIV and the relationship of disclosure to stigma and social support. The CHAI (Coping, HIV, and Affect Interview) Study was a longitudinal cohort study that followed individuals who were newly diagnosed with HIV. The study took place from October 2004 to June 2008 in the San Francisco Bay Area. This sample includes data from 50 participants who were interviewed 1, 3, and 9 months following diagnosis with HIV. We identified four main approaches to HIV disclosure that revealed distinct differences in how participants appraised disclosure, whether disclosure was experienced as stressful, and whether disclosure or nondisclosure functioned as a way of coping with an HIV diagnosis. Implications of these findings for disclosure counseling are discussed.

A randomized study of the effects of mindfulness training on psychological well-being and symptoms of stress in patients treated for cancer at 6-month follow-up.

BACKGROUND: There is increasing evidence showing beneficial effects of mindfulness and mindfulness training on various indicators of mental and physical health. PURPOSE: This paper reports the 6-month follow-up effects of a mindfulness stress reduction training program among patients treated for cancer on perceived stress, depression, anxiety, post-traumatic stress symptoms, positive states of mind, coping self-efficacy, and mindfulness. METHODS: Patients with a previous cancer diagnosis were recruited and randomized into an intervention group or a waiting list control group. The intervention consisted of an 8-week mindfulness training course. RESULTS: Compared to participants in the control group, the intervention group showed a larger increase in mindfulness at 6-month follow-up. However, there were no differences on any of the other outcomes between the intervention and control groups. Continued meditation practice was associated with a significant reduction in post-traumatic stress symptoms of avoidance. CONCLUSIONS: The study draws attention to the need to better understand the mechanisms behind the effect of mindfulness training and to potential modification of mindfulness interventions to promote sustained benefits over time.

A positive affect intervention for people experiencing health-related stress: development and non-randomized pilot test.

In this article we present background, theoretical rationale, and pilot data on the development of an intervention designed to increase positive affect in people living with serious health-related stress. This proof-of-concept study demonstrated that a multiple-component positive affect intervention is feasible and acceptable for people newly diagnosed with HIV. Retention in the intervention and adherence to home practice were high. Participants reported significant increases in positive affect and significant decreases in negative affect. This positive affect intervention can serve as a template for programs to be developed to help people experiencing health-related and other types of life stress.

Mindfulness-based stress reduction for HIV treatment side effects: a randomized, wait-list controlled trial.

CONTEXT: Advances in antiretroviral therapy (ART) for HIV offer life-extending benefit; however, the side effects associated with ART use negatively impact quality of life and medication adherence among people living with HIV. OBJECTIVES: This study tested the efficacy of Mindfulness-Based Stress Reduction (MBSR) for reducing ART symptoms and bother/distress related to ART side effects. Secondary aims were to test the impact of MBSR on medication adherence and psychological functioning. METHODS: Seventy-six people living with HIV who were actively taking ART and reported distress from ART-related side effects were randomly assigned to an MBSR program or a wait-list control (WLC) standard care condition. We measured side effects, ART adherence, perceived stress, depression, positive and negative affect, and mindfulness at three time points: baseline, three-month follow-up, and six-month follow-up. Side effects and related distress were assessed separately from other symptoms. RESULTS: Compared with a WLC, participants in the MBSR condition experienced a reduction in the frequency of symptoms attributable to ARTs at three months post-intervention (mean difference=0.33; 95% confidence interval [CI]=0.01, 0.66; t(132)=2.04, P=0.044) and six months post-intervention (mean difference=0.38; 95% CI=0.05, 0.71; t(132)=2.27, P=0.025). MBSR participants also experienced a reduction in distress associated with those symptoms at three months post-intervention (mean difference=0.47; 95% CI=0.003, 0.94; t(132)=1.99, P=0.048) compared with the WLC condition. CONCLUSION: MBSR is a promising approach for reducing HIV treatment-related side effects.

The association between dispositional mindfulness, psychological well-being, and perceived health in a Swedish population-based sample.

OBJECTIVES: There is increasing recognition of the links between mindfulness, decreased stress, and healthier psychological functioning. However, the majority of this research has been conducted in US samples and the mechanisms through which mindfulness decreases stress and increases well-being are not well understood. The aim of this study was to examine the relations between mindfulness and psychological functioning in a general population sample in Sweden. DESIGN: This cross-sectional study examined the association of mindfulness and five subscales of mindfulness with depression, anxiety, positive states of mind (PSOM), and perceived health. METHODS: In the spring of 2007, a random population-based sample of N= 1,000 individuals aged 18-60 years in Sweden was contacted by mail with a request to participate in the study. RESULTS: Mindfulness and some of its subscales, in particular Acting with awareness and Non-reactivity to inner experiences, were strongly related to PSOM and perceived health, and inversely related to depression and anxiety. Tests of the moderating role of mindfulness showed that the associations of perceived stress with depression and perceived health were diminished for those with higher levels of mindfulness. CONCLUSIONS: Mindfulness is strongly related to well-being and perceived health. Results suggest that dispositional mindfulness might buffer against the negative influence of perceived stress on psychological well-being. These findings give additional support for the use of mindfulness training as a way of improving psychological functioning among people experiencing stress.

Self-report mindfulness as a mediator of psychological well-being in a stress reduction intervention for cancer patients--a randomized study.

BACKGROUND: There is increasing recognition of mindfulness and mindfulness training as a way to decrease stress and increase psychological functioning. PURPOSE: The aims of this study were to examine the effects of mindfulness stress reduction training on perceived stress and psychological well-being and to examine if changes in mindfulness mediate intervention effects on these outcomes. METHODS: Seventy women and one man with a previous cancer diagnosis (mean age 51.8 years, standard deviation = 9.86) were randomized into an intervention group or a wait-list control group. The intervention consisted of an 8-week mindfulness training course. RESULTS: Compared to participants in the control group, participants in the mindfulness training group had significantly decreased perceived stress and posttraumatic avoidance symptoms and increased positive states of mind. Those who participated in the intervention reported a significant increase in scores on the five-facet mindfulness questionnaire (FFMQ) when compared to controls. The increase in FFMQ score mediated the effects of the intervention on perceived stress, posttraumatic avoidance symptoms, and positive states of mind. CONCLUSIONS: This study indicates that the improvements in psychological well-being resulting from mindfulness stress reduction training can potentially be explained by increased levels of mindfulness as measured with the FFMQ. The importance of these findings for future research in the field of mindfulness is discussed.

Affective correlates of stimulant use and adherence to anti-retroviral therapy among HIV-positive methamphetamine users.

The use of stimulants has important implications for HIV prevention and care. However, few investigations have examined psychological correlates of substance use and adherence to anti-retroviral therapy (ART) among HIV-positive stimulant users. This cross-sectional investigation examined affective correlates of stimulant use and ART adherence among HIV-positive methamphetamine users. In total, 122 HIV-positive men who have sex with men or transgendered individuals on ART who reported using methamphetamine in the past 30 days were recruited from the community. HIV-specific traumatic stress was consistently and independently associated with more frequent cocaine/crack use (but not with methamphetamine use). Positive affect was independently associated with a decreased likelihood of reporting any injection drug use and an increased likelihood of reporting perfect ART adherence. HIV-specific traumatic stress may be an important determinant of increased cocaine/crack use in this population. Positive affect may increase the likelihood that individuals will refrain from injection drug use and achieve high levels of ART adherence.
