Randomized controlled trial of a positive affect intervention for people newly diagnosed with HIV

Narratives of Disconnection: A Life Course Perspective of Methamphetamine Use Among Sexual Minority Men Living with HIV

BACKGROUND

Sexual minority men (SMM) are exposed to societal and structural stressors that translate into poor health outcomes. One such outcome is substance use, which research has long documented as a prominent disparity among SMM. Methamphetamine is a particularly deleterious substance for SMM because its use is often framed as a coping response to social and structural stressors.

METHOD

Guided by stress and coping theory and a life course perspective, the purpose of this qualitative study is to assess the development of coping strategies in the context of prominent social and structural determinants among SMM living with HIV who use methamphetamine.

RESULTS

Data were collected from 2016 to 2018 via in-depth interviews with 24 SMM living with HIV who use methamphetamine in San Francisco, CA. Mean age of participants was 47 and over half self-identified as ethnoracial minorities. Narrative analysis surfaced a sequential pattern of disconnection at foundational, relational, and recovery levels. This analysis revealed that multi-level stressors were present across the life course that amplified engagement in methamphetamine use.

CONCLUSION

Findings highlight the benefits of holistic, integrated, and trauma-informed approaches to address the function of methamphetamine use as a response to societal, cultural, and institutional processes of stigmatization and discrimination. Peer-based approaches may also be beneficial to reframe the ways in which SMM living with HIV who use methamphetamine form and sustain relationships.

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.

In the Interest of Time: Assessing the Role of Resilience Across an Intergenerational Sample of People Living with HIV

BACKGROUND

Biomedical advances have improved the quality of life of people living with HIV (PLWH); however, barriers to optimal well-being remain. A key feature in understanding the lived experiences of PLWH is resilience. The concept of resilience is quite complex in terms of its antecedents and expressions, suggesting the need for more nuanced understandings of how it could be harnessed to better support this population.

METHOD

The concept of resilience was explored in a qualitative study involving 22 PLWH, selectively sampled by era of diagnosis. Through interviews focused on context and experiences of living with HIV, the sample highlighted resilience processes corresponding to Positive reappraisal of life events, Positive reappraisal of self, and Community as resilience.

RESULTS

Participants who have lived with HIV longer more commonly described engaging in psychological processes of resilience, whereas those who were more recently diagnosed reported engaging in more social processes. However, these processes were not mutually exclusive and the ability to perform resilience through community seems to be key to optimizing outcomes, irrespective of era of diagnosis.

CONCLUSION

PLWH are a heterogeneous population where engagement in distinct processes of resilience may have important implications for optimal social and health outcomes. Better understanding of the distinct and diverse pathways through which PLWH engage in resilience may inform interventions promoting optimal well-being.

Fostering resilience in adolescence and young adulthood: Considerations for evidence-based, patient-centered oncology care

Adolescence and young adulthood are times of growth and change. For adolescents and young adults (AYAs) who are diagnosed with cancer, the demands of illness may compound normal developmental challenges and adversely affect physical, emotional, and social health. Nevertheless, AYAs have a tremendous capacity for psychosocial adaptation and resilience. Informed by the Transactional Model of Stress and Coping, observational studies in AYA oncology suggest consistent individual, social, and existential resources that may promote resilience. To date, few interventions have been designed to examine whether resilience can be taught and whether doing so affects patient-centered outcomes. Findings point to the potential value of multicomponent programs that include various skills-building strategies, such as stress management, mindfulness, gratitude, and positive reappraisal coping, among others. New research directions include the need to evaluate delivery strategies to enhance participant adherence and retention (e.g., eHealth modalities, optimization studies) and to examine program effectiveness in community-based oncology practices (e.g., less resource-rich settings in which most AYAs receive care). Ultimately, this scholarship may inform, refine, and strengthen intervention science in resilience more broadly.

Randomized controlled trial of a positive emotion regulation intervention to reduce stress in family caregivers of individuals with Alzheimer's disease: protocol and design for the LEAF 2.0 study

BACKGROUND

Caring for a loved one with Alzheimer's disease can be stressful, resulting in poorer emotional and physical health among family caregivers. Although supportive resources for caregivers are available, distance, caregiver health, and the daily demands of caregiving are barriers to access. Based on research demonstrating the importance of positive emotions in coping with stress, our previous trial showed that dementia caregivers who participated in facilitated, web-based delivery of a positive emotion regulation intervention called LEAF (Life Enhancing Activities for Family caregivers) experienced increased positive emotion and decreased depression and anxiety. Building on this evidence, the LEAF 2.0 study aims to test whether web-based, self-guided delivery can confer similar benefits for caregivers of individuals with Alzheimer's disease.

METHODS

This paper presents the design and methods for LEAF 2.0, a 3-arm web-based randomized controlled trial (N = 500) in which family caregivers of patients with Alzheimer's disease (AD) are randomized to (1) the LEAF intervention facilitated remotely via the web (N = 200), (2) the LEAF intervention self-guided online (N = 200), or (3) an emotion reporting control (N = 100), which then crosses over to the intervention after approximately 6 months, half to the facilitated arm and half to the self-guided arm. We aim to (1) compare the effect of the facilitated and self-guided LEAF positive emotion interventions to an emotion reporting control condition on AD caregiver well-being (positive emotion, depression, anxiety, and perceived stress) and secondary outcomes (caregiving burden, caregiving self-efficacy, positive aspects of caregiving, quality of care, and AD patient quality of life); (2) assess whether effects are mediated by improvements in positive emotion or other aspects of caregiver well-being; and (3) test whether caregiver age or gender or the care recipient's dementia severity moderates the effects of the intervention.

DISCUSSION

If demonstrated to be effective, LEAF can be widely disseminated and ultimately have a significant impact on the stress experienced by AD caregivers and the well-being of people living with Alzheimer's disease.

A latent profile analysis of doctors' joy in work at public hospitals

Introduction

When doctors' work stress increases, their joy in work decreases, severely affecting the quality of care and threatening patient safety. Analysis of the latent categories of joy in work of doctors in public hospitals and the differences in the characteristics of each category can help uncover hidden messages that enhance doctors' joy in work.

Methods

Questionnaires were administered to 426 doctors working in public hospitals using the general information questionnaire and the public hospital doctor's joy in work evaluation scale. Upon identifying their potential categories using latent profile analysis, chi-square test, and multinomial logistic regression were performed to analyze the differences in the characteristics of each category.

Results

The 426 public hospital doctors could be divided into three potential categories: "low joy in work" (11.27%), "medium joy in work" (59.86%), and "high joy in work" (28.87%). Most of the doctors did not have much joy in work, with 71.13% of them having "low to medium joy in work." Doctors who work in secondary or tertiary hospitals, have a personnel agency or contract, and are older than 45 years are more likely to belong to the "low joy in work" category. Some of the protective factors are having an average monthly income (RMB) of 10,001-15,000 yuan and having a fair or good self-rated health status.

Conclusion

There are obvious classification characteristics of doctors' level of joy in work. Hospital managers can take commensurate actions to improve their joy in work, thereby improving patient safety and the quality of medical services.

Provider Perspectives on Multi-level Barriers and Facilitators to PrEP Access Among Latinx Sexual and Gender Minorities

Although pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention intervention, inequities in access remain among Latinx sexual and gender minorities (LSGM). There is also a gap in the PrEP literature regarding providers' perspective on access inequities. This qualitative case study sought to explore barriers and facilitators to PrEP engagement in a community-based integrated health center primarily serving Latinx populations in Northern California. We conducted in-depth, semi-structured interviews with providers (9/15) involved in PrEP services and engaged in a constructivist grounded theory analysis consisting of memoing, coding, and identifying salient themes. Three participants worked as medical providers, three as outreach staff, and one each in planning, education, and research. The analysis surfaced four themes: geopolitical differences, culture as barrier, clinic as context, and patient strengths and needs. Participants referenced a lack of resources to promote PrEP, as well as the difficulties of working within an institution that still struggles with cultural and organizational mores that deprioritize sexual health. Another barrier is related to sexual health being positioned outside of patients' immediate needs owing to structural barriers, including poverty, documentation status, and education. Participants, however, observed that peer-based models, which emboldened their decision-making processes, were conducive to better access to PrEP, as well as allowing them to build stronger community ties. These data underscore the need for interventions to help reduce sexual stigma, promote peer support, and ameliorate structural barriers to sexual healthcare among LSGM.

A web-based positive-affect intervention to reduce stress and improve well-being in women living with HIV - feasibility and acceptability of a single-arm, pilot study

Women living with HIV (WLWH) experience high rates of depression but are underrepresented in mental health research. Positive emotions are associated with beneficial health outcomes in WLWH and should be a targeted component of psychological interventions in this population. Positive psychological interventions aim to increase positive emotions through the use of simple exercises, such as keeping a gratitude journal. We conducted a single-arm feasibility/acceptability study of a five-week, self-guided, web-based positive affect skills intervention in a sample of WLWH (N = 23) who also participate in a longitudinal observational study, the Women's Interagency HIV Study. The intervention was feasible as measured by home practice and post-intervention assessment completion, and acceptable as measured by exit interview feedback regarding recommendation of the program to friends or others living with HIV. On average, participants completed home practice for about 8 out of 9 skills. The mean response for recommendation of the program to a friend was 9.26/10 (SD = 1.63) and the mean response for recommendation of the program to others living with HIV was 9.68/10 (SD = 0.82). Participant feedback will be used to adapt and enhance the delivery of this intervention. Further studies are needed to assess efficacy and impact on psychological outcomes.

Exploring self-esteem during expressive writing about trauma predicts decreased depression in people with HIV

Self-esteem is often negatively impacted by trauma. Low self-esteem has been related to significantly worse depression in people with HIV (PWH). This study explores whether the expression of words related to self-esteem during a 4-session augmented trauma writing intervention predicted post-traumatic stress, depressive symptoms, and health outcomes 6-months later. Ninety-five PWH completed four 30-minute augmented trauma writing sessions in the intervention arm of a randomized controlled trial. One augmented session was devoted to self-esteem. Two individuals coded trauma essays for number of self-esteem words. CD4+ and viral load data were collected, and the Davidson PTSD Scale and the Hamilton Depression Rating Scale were administered at baseline, one-, and six-month follow-up. Greater total self-esteem words were related to lower depressive symptoms at 6-months, controlling for depressive symptoms at study entry, age, race, and education (t(80) = -2.235, ß = -0.239, SE = 0.283, p < 0.05, 95% CI [-1.195, -.069). Total self-esteem words were not predictive of PTSD, viral load, or CD4+ at 6-months. Exploring self-esteem when writing about and processing a traumatic event could be an important mechanism for decreasing depressive symptoms among PWH. Research is needed to test augmented expressive writing interventions that support efforts to bolster self-esteem in PWH.

Veterinary Students' Sense of Belonging: Growing Community with Small Group Academic Enhancement

A student's sense of belonging to a university is associated with success in academic setting, happiness, and satisfaction. It is therefore unsurprising that universities commonly strive to improve student measures of belonging especially considering its negative correlation with attrition rates. This study documents the implementation and assessment of a new curricular intervention at Ross University School of Veterinary Medicine (RUSVM) and measures associated changes in students' feeling of belonging to the university and accountability for their success. Specifically, small, group, faculty-guided weekly discussion sessions were introduced to the Veterinary Professional Foundation (VPF) course to complement a series of updated didactic only lectures. Voluntary surveys ("belonging to the university scale" [1] and the "personal accountability in education scale" [2]) were utilized to document student attitudes and feelings surrounding these variables. Likert scores from a control group of students who completed the VPF course prior to the curricular change were compared to the intervention group who engaged in the weekly guided discussion sessions via a Wilcoxon test. The intervention group reported significantly improved feelings of belonging to the university (p-values ranging from 0.008 to 0.027). Minimal change was noted between groups associated with accountability. The addition of weekly small group meetings has proven valuable at RUSVM in improving student sense of belonging to the university. Further research is indicated to determine if accountability may be improved over a longer period of monitoring with continued interventions.

An eHealth, Positive Emotion Skills Intervention for Enhancing Psychological Well-Being in Young Adult Cancer Survivors: Results from a Multi-Site, Pilot Feasibility Trial

BACKGROUND

Young adult (YA) cancer survivors experience clinically significant distress and have limited access to psychosocial support. Given growing evidence for unique adaptive benefits of positive emotion in the context of health-related and other life stress, we developed an eHealth positive emotion skills intervention for post-treatment survivors called EMPOWER (Enhancing Management of Psychological Outcomes With Emotion Regulation) and evaluated feasibility and proof of concept for reducing distress and enhancing well-being.

METHOD

In this single-arm pilot feasibility trial, post-treatment YA cancer survivors (ages 18-39) participated in the EMPOWER intervention which included 8 skills (e.g., gratitude, mindfulness, acts of kindness). Participants completed surveys at baseline (pre-intervention), 8 weeks (post-intervention), and 12 weeks (1-month follow-up). Primary outcomes included feasibility (assessed by participation percentage) and acceptability (would recommend EMPOWER skills to a friend). Secondary outcomes included psychological well-being (mental health, positive affect, life satisfaction, meaning/purpose, general self-efficacy) and distress (depression, anxiety, anger).

RESULTS

We assessed 220 YAs for eligibility; 77% declined. Of those screened, 44 (88%) were eligible and consented, 33 began the intervention, and 26 (79%) completed the intervention. Overall retention was 61% at 12 weeks. Average acceptability ratings were high (8.8/10). Participants (M = 30.8 years, SD = 6.6) were 77% women, 18% racial/ethnic minorities, and 34% breast cancer survivors. At 12 weeks, EMPOWER was associated with improved mental health, positive affect, life satisfaction, meaning/purpose, and general self-efficacy (ps < .05, ds = .45 to .63) and decreased anger (p < .05, d =  - 0.41).

CONCLUSION

EMPOWER demonstrated evidence of feasibility and acceptability as well as proof of concept for enhancing well-being and reducing distress. Self-guided, eHealth interventions show promise for addressing YA cancer survivors' needs and warrant additional research to optimize survivorship care.

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.

Feasibility, Acceptability, and Preliminary Efficacy of a Positive Affect Skills Intervention for Adults With Fibromyalgia

Background and Objectives

To examine the feasibility, acceptability, and preliminary efficacy of a positive affect skills intervention for middle-aged and older adults with fibromyalgia syndrome (FMS).

Research Design and Methods

Ninety-five participants with FMS aged 50 and older (94% female) were randomized to 1 of 2 conditions: (a) Lessons in Affect Regulation to Keep Stress and Pain UndeR control (LARKSPUR; n = 49) or (b) emotion reporting/control (n = 46). LARKSPUR included 5 weeks of skill training that targeted 8 skills to help foster positive affect, including (a) noticing positive events, (b) savoring positive events, (c) identifying personal strengths, (d) behavioral activation to set and work toward attainable goals, (e) mindfulness, (f) positive reappraisal, (g) gratitude, and (h) acts of kindness. Outcome data were collected via online surveys at baseline, postintervention, and 1-month follow-up.

Results

Completion rates (88%) and satisfaction ratings (10-point scale) were high (LARKSPUR: M = 9.14, standard deviation (SD) = 1.49; control: M = 8.59, SD = 1.97). Improvements were greater in LARKSPUR participants compared with control participants on measures of positive affect (Cohen's d = 0.19 [0.15, 0.24]), negative affect (Cohen's d = -0.07 [-0.11, -0.02]), and pain catastrophizing (Cohen's d = -0.14 [-0.23, -0.05]). Improvements in positive affect (Cohen's d = 0.17 [0.13, 0.22]) and negative affect (Cohen's d = -0.11 [-0.15, -0.06]) were maintained at 1-month follow-up. Dose-response analyses indicated that intervention engagement significantly predicted pre-to-post and post-to-follow-up reductions in pain catastrophizing.

Discussion and Implications

The current preliminary findings add to existing literature and highlight the specific potential of internet-delivered positive affect skills programs for adults with FMS.

Chronic Pain and Affective Experiences Associated with Daily Stressors and Uplifts

People with chronic pain often report greater reactivity to stress than those without pain. This finding is consistent with the kindling hypothesis, which states that continued exposure to stressors only heightens negative affect and dampens positive affect. Yet, people with chronic pain may also respond more positively to enjoyable activities, or uplifts, as well. Chronic pain is related to lower levels of well-being, and the fragility of positive affect model explains how individuals with lower levels of well-being often exhibit stronger, more positive responses to daily uplifts than their less distressed peers. Our study used the National Study of Daily Experiences to assess daily stressors, positive uplifts, and positive and negative affect across eight days among those with and without chronic pain. Participants (nChronicPain=658, nNoPain=1,075) were predominately Non-Hispanic White (91%), 56% female, and averaged 56 years old. Results revealed that people with chronic pain had lower levels of daily positive affect and higher levels of negative affect, yet the two groups did not vary in their stressor-related negative and positive affect. In contrast, having chronic pain was related to a greater increase in positive affect and greater decreases in negative affect on days with positive uplifts. Findings suggest that intervention efforts focusing on uplifts may be particularly helpful for people who report chronic pain.

Positive Psychology Interventions in Medical Populations: Critical Issues in Intervention Development, Testing, and Implementation

Positive psychological well-being is prospectively associated with superior health outcomes. Positive psychology interventions have promise as a potentially feasible and effective means of increasing well-being and health in those with medical illness, and several initial studies have shown the potential of such programs in medical populations. At the same time, numerous key issues in the existing positive psychology literature must be addressed to ensure that these interventions are optimally effective. These include (1) assessing the nature and scope of PPWB as part of intervention development and application; (2) identifying and utilizing theoretical models that can clearly outline potential mechanisms by which positive psychology interventions may affect health outcomes; (3) determining consistent, realistic targets for positive psychology interventions; (4) developing consistent approaches to the promotion of positive psychological well-being; (5) emphasizing the inclusion of diverse samples in treatment development and testing; and (6) considering implementation and scalability from the start of intervention development to ensure effective real-world application. Attention to these six domains could greatly facilitate the generation of effective, replicable, and easily adopted positive psychology programs for medical populations with the potential to have an important impact on public health.

Positive Psychological Intervention Effects on Depression: Positive Emotion Does Not Mediate Intervention Impact in a Sample with Elevated Depressive Symptoms

Positive psychological interventions (PPIs), programs that specifically target positive emotions, cognitions, and behaviors, have been shown to reduce depression and improve other aspects of psychological well-being. However, potential pathways linking PPIs to better outcomes have been under-explored. In this paper, we report the results of a randomized trial of a self-guided online delivered PPI called MARIGOLD (Mobile Affect Regulation Intervention with the Goal of Lowering Depression). Participants with elevated depression were randomized to receive MARIGOLD (n = 539) or an emotion reporting control condition (n = 63). In addition to testing direct effects of the intervention on depressive symptoms, we explored whether positive or negative emotion-operationalized as past day, past week, reactivity, or flexibility-mediated the intervention impact on depression. Results demonstrated that participants in the MARIGOLD condition had reduced depressive symptoms compared to controls and, although the effect did not reach statistical significance, reductions in past day negative emotion appeared to mediate this effect. Contrary to hypotheses, the intervention did not increase positive emotion compared to the control condition. Discussion focuses on the need for future studies to continue investigating the mechanisms of action for PPIs with emphasis on theoretically-based measurement and operationalization of emotion and other potential mediators to maximize the ultimate impact of PPIs on psychological well-being.

Exploring Retention, Usage, and Efficacy of Web-Based Delivery of Positive Emotion Regulation Skills During the COVID-19 Pandemic

COVID-19 prompted distress and increased reliance on digital mental health interventions, which previously demonstrated low rates of retention and adherence. This single-arm trial evaluated whether self-guided, web-based, positive affect regulation skills (PARK) were engaging and associated with changes in well-being during the pandemic. Over 6 weeks, PARK delivers brief lessons and practices in skills designed to increase positive emotions: noticing positive events, savoring, gratitude, mindfulness, positive reappraisal, personal strengths, and self-compassion. Patient-Reported Outcome Measurement Information System (PROMIS) computer adaptive tests of anxiety, depression, social isolation, positive affect, and meaning and purpose were administered at baseline, post-intervention, and 6 months after baseline. Retention and usage of PARK were measured by the web-based assessment and intervention platforms. The sample (n = 616) was predominantly female, non-Hispanic, white, and well-educated. Of those who completed baseline, only 42% completed a follow-up assessment; 30% never logged into PARK. Among those who did, 86% used at least one skill, but only 14% completed PARK. Across retention and usage metrics, older age predicted more engagement. In multivariable models, people of color and people with greater baseline anxiety were more likely to complete PARK. All well-being indicators improved over time, with greater improvements in anxiety and social isolation among participants who accessed at least one PARK skill compared to those who did not. Retention and usage rates mirrored pre-pandemic trends, but within this select sample, predictors of engagement differed from prior research. Findings underscore the need for additional efforts to ensure equitable access to digital mental health interventions and research. Trials registration: NCT04367922.

Co-design of digital health interventions with young people: A scoping review

Introduction

Innovative health promotion strategies are crucial for enhancing global quality of life and curbing premature deaths. Digital health promotion is particularly impactful for young individuals often using internet-connected devices. Collaborative methodologies in digital intervention research offer insights into supporting youth during key life stages, such as adolescence. This review sought to examine the literature on digital health interventions for youth co-designed via participatory frameworks.

Methods

Following the Joanna Briggs Institute Manual and an adapted Arksey & O'Malley's 6-stage framework, this review utilised the PRISMA-ScR checklist for structured reporting. Peer-reviewed research where young individuals (15-35 years) contributed to digital health intervention design was analysed. Systematic synthesis adhered to Braun & Clarke's Thematic Analysis Guidelines, mapping data to research queries and thematic framework.

Results

Eighteen articles were systematically synthesised, revealing seven main themes: digital tool, inquiry field, report aim, participatory activities, intervention attributes and behavioural change support. Seventeen distinctive digital health interventions were assessed, mostly within risk mitigation and mental health domains. Predominantly, interventions were web-based, with mental wellness websites emerging as the prevalent tool. User experience testing stood out as the primary reported outcome.

Conclusion

Several innovative digital health interventions targeting youth have been identified. Platforms including social media, specialised apps, websites and video games are instrumental for health advice and clinical support dissemination, overcoming access and cost barriers. Participatory techniques are integral for the efficacy of digital health resources, encompassing youth aspirations and anticipations. Continued efforts will enrich comprehension of optimal practices in digital health promotion and intervention formulation.

Four-Year Trajectories of Internal Strengths and Socioemotional Support Among Middle-Aged and Older Adults with HIV

Positive psychological attributes are associated with better health outcomes, yet few studies have identified their underlying constructs and none have examined their temporal trajectories in clinical vs. non-clinical samples. From data collected over 4 years from people with HIV (PWH) and HIV-uninfected (HIV-) participants, we identified two latent factors (internal strengths; socioemotional support) based on responses to seven positive psychological attributes. Internal strengths increased over 4 years for PWH, but not for HIV- comparisons. Socioemotional support did not change significantly in either group. Lower internal strengths and worse socioemotional support were related to greater depressive symptoms. We speculate that improvement in internal strengths in PWH could reflect their being in care, but this requires further study to include PWH not in care. Given the apparent malleability of internal strengths and their association with improved health outcomes, these attributes can serve as promising intervention targets for PWH.

Can positive psychological interventions improve health behaviors? A systematic review of the literature

Positive psychological interventions (PPIs), which aim to cultivate psychological well-being, have the potential to improve health behavior adherence. This systematic review summarized the existing literature on PPI studies with a health behavior outcome to examine study methodology, quality, and efficacy. Of the 27 identified studies, 20 measured physical activity, eight measured medication adherence, seven measured diet, and three measured smoking (eight targeted multiple behaviors). Twenty studies were randomized controlled trials (RCTs; 13 fully powered), and seven had a single-arm design. Study samples were usually adults (n = 21), majority non-Hispanic white (n = 15) and female (n = 14), and with a specific disease (e.g., diabetes, n = 16). Most interventions combined a PPI with health behavior-focused content (n = 17), used a remote delivery method (n = 17), and received a moderate or low study quality rating. Overall, 19/27 studies found a health behavior improvement of at least medium effect size, while six of the 13 studies powered to detect significant effects were statistically significant. Of the behaviors measured, physical activity was most likely to improve (14/20 studies). In summary, PPIs are being increasingly studied as a strategy to enhance health behavior adherence. The existing literature is limited by small sample size, low study quality and inconsistent intervention content and outcome measurement. Future research should establish the most effective components of PPIs that can be tailored to different populations, use objective health behavior measurement, and robustly examine the effects of PPIs on health behaviors in fully powered RCTs.

The More the Better, Only in the Longer Term: A Cluster Randomized Controlled Trial to Evaluate a Compound Intervention Among Mainland Chinese Immigrants in Hong Kong

Barriers to adaptation faced by mainland Chinese immigrants to Hong Kong can be reduced by improving two targets of adaptation: information about negotiating their new environment and psychological well-being. We developed and evaluated a Compound intervention to address these two domains simultaneously and compared its effects to two separate interventions exclusively targeting either information about Hong Kong or psychological well-being. This cluster randomized controlled trial assigned 251 immigrants to an information provision arm (IP, n = 84) targeting knowledge and adaptation difficulties, a psychological well-being enhancement arm (WBE, n = 80) targeting resilience and mental health, or a Compound arm (i.e., IP + WBE, n = 87). The Compound arm showed stronger effects from baseline to postintervention on knowledge than the WBE arm. From postintervention to 6-month follow-up, the Compound arm showed better sustained effects on knowledge and adaptation difficulties than the IP arm and on resilience and mental health than the WBE arm. Additionally, participants in the Compound arm with more baseline depressive symptoms showed greater improvements in adaptation difficulties and general mental health than those with fewer symptoms. The study demonstrated the longer-term effectiveness of the Compound intervention and its greater benefits for immigrants with more depressive symptoms.

Lessons in Affect Regulation to Keep Stress and Pain UndeR control (LARKSPUR): Design of a randomized controlled trial to increase positive affect in middle-aged and older adults with fibromyalgia

BACKGROUND

Fibromyalgia syndrome (FMS) is a leading cause of functional limitations and disability for which there is no cure. Positive psychological interventions for improving health have received increasing attention, but evidence of the feasibility, acceptability, and impact of such interventions in adult populations with FMS is limited.

OBJECTIVES

To describe the rationale and design of a 5-week, online positive affect skills intervention, LARKSPUR: Lessons in Affect Regulation to Keep Stress and Pain UndeR control.

METHODS

FMS participants (N = 90) will be randomized to one of two conditions: (1) LARKSPUR or (2) emotion reporting/attention control. LARKSPUR is an online multicomponent intervention that targets eight skills to help foster positive affect: (1) noticing positive events, (2) savoring positive events, (3) identifying personal strengths, (4) behavioral activation to set and work toward attainable goals, (5) mindfulness, (6) positive reappraisal, (7) gratitude, and (8) acts of kindness. The primary outcomes include feasibility (i.e., recruitment, retention, adherence) and acceptability (i.e., helpfulness, usability, satisfaction). Secondary outcomes include pain intensity and pain interference.

SIGNIFICANCE

If feasibility and acceptability metrics are met and reductions in pain outcomes are achieved, we will undertake future efficacy and effectiveness trials of LARKSPUR among older adults with FMS.

A positive psychology group intervention in Greek university students by the counseling center: Effectiveness of implementation

Most institutions in higher education have emphasized success in knowledge while overlooking Students' wellbeing. The present study aimed to examine the effectiveness of the implementation of a 5-week positive psychology group intervention to a sample of 69 students that were assigned to the intervention (N = 34) and the control group (N = 35). Pre and post measures were taken assessing positive and negative emotions, resilience, happiness, optimism, and self-esteem. In particular, Modified Differential Emotions Scale (mDES), Connor-Davidson Resilience Scale (CD-RISC), Subjective Happiness Scale (SHS), Life Orientation Test-Revised (LOT-R), and Rosenberg Self-Esteem Scale (RSES) were administered to the participants. A mixed measures design was employed with the condition experimental vs. control group as the between-participants factor and time, namely, baseline vs. post-intervention as the within-participants factor. Except for optimism, compared with students in the control group, students in the experimental group showed no significant differences at baseline and experienced a significant increase in positive emotions and resilience in the post-test. On the contrary, the control group demonstrated no significant difference at post-test. Additionally, the students of the intervention group reported significantly higher levels in all measures in comparison with the students of the control group, except resilience, at post-test. However, when the interaction of design and time was considered, the increase in positive emotions solely emerged as a significant result of the intervention. The implementation of a positive psychology group intervention program can be effective in helping students experiencing positive emotions. More research is needed in order to refine and improve the application of such a program in a university setting, in regard to long term intervention.

Mechanisms of quality-of-life improvement in treatment for alcohol use disorder

OBJECTIVE

For individuals in alcohol use disorder (AUD) treatment, many argue that holistic indicators such as quality of life (QoL) should be more consistently used in addition to drinking-related indicators. QoL increases from pre- to post-AUD treatment, but the mechanisms are unclear. The present study examined the roles of positive and negative affect in QoL change during AUD treatment and additionally explored the relationship between QoL change and medication adherence.

METHOD

We examined the mediating roles of end-of-treatment positive affect (i.e., vigor) and negative affect (i.e., stress and tension) in the relationship between baseline (BL) and 26-week QoL among participants in the Combined Pharmacotherapies and Behavioral Interventions for Alcohol Dependence study randomized to medication management (MM; n = 468) or medication management plus combined behavioral intervention (MMCBI; n = 479) for AUD. We also explored whether changes in QoL were associated with medication adherence.

RESULTS

Change in psychological health QoL was mediated by increased vigor (i.e., positive affect) and decreased stress, and change in environmental QoL was mediated by decreased stress. There were also differences by treatment group, with stress mediating changes in environmental QoL among participants in MM, and vigor mediating changes in psychological health QoL among participants in MMCBI. Medication adherence was not associated with greater QoL after controlling for posttreatment alcohol use.

CONCLUSIONS

The present study identified potential mechanisms of QoL change in AUD treatment, thus contributing to the growing knowledge surrounding alternative indicators of treatment success for AUD treatment and recovery. Targeting affective states and stress during treatment may improve QoL and recovery outcomes for persons with AUD. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Adapting, testing, and refining a resilience intervention for older women with HIV: An open pilot study

Half of persons with HIV in the United States (US), many of whom are women, are over age 50. Aging women with HIV (WWH) face unique biopsychosocial challenges, including stigma, the physiological effects of aging, and illness-associated stressors. Resilience interventions can build awareness of such stressors and aid in facilitating the relaxation response; however, no existing interventions specifically cater to the needs of older WWH. The content of the Relaxation Response Resiliency Program, which teaches positive psychology strategies, relaxation techniques, and cognitive behavioral skills, was adapted for older WWH. Thirteen WWH over 50 participated in an open pilot of the adapted intervention to iteratively refine the program and its procedures. Participants attended either 8 or 10 weekly group sessions; three groups were conducted in total. Pre- and post-intervention assessments and qualitative exit interviews were conducted. Among completers, an increase in resilience was observed. Though significance testing was not conducted, social support also increased, and depression, anxiety, and HIV stigma decreased from pre- to post-intervention. Over half of eligible women enrolled; completers reported high satisfaction with the program. However, retention was difficult; six participants withdrew or were lost to follow-up. Mean number of sessions attended was 3.5 in the 8-session group and 5 in the 10-session groups. In this small sample, the adapted intervention led to a clinically meaningful increase in resilience, though recruitment and retention were challenging. Further refinements to the intervention are needed to minimize attrition and increase acceptability before additional testing is initiated.

Development of an Implementation Facilitation Strategy to Link Mental Health Screening and eHealth Intervention for Clients in Ryan White-Funded Clinics in Chicago

BACKGROUND

To reduce the impact of depression on people living with HIV, we are implementing a clinic-based behavioral health screener and referral to Optimizing Resilience and Coping with HIV through Internet Delivery, an evidenced-based intervention. We used the Consolidated Framework for Implementation Research to identify contextual barriers and facilitators in advance of implementation.

SETTING

Sixteen Chicagoland area Ryan White Medical Case Management sites.

METHODS

We conducted a sequential mixed-methods study with medical case managers and supervisors. Participants completed an online survey assessing Consolidated Framework for Implementation Research domains, scored on a 1 (strongly disagree) to 5 (strongly agree) scale. Survey results informed a purposive sampling frame and interview protocol. Interviews were analyzed by rapid qualitative analysis.

RESULTS

On average, survey respondents (n = 58) slightly agreed with positive views of team culture, learning climate, and implementation readiness (mean = 3.80-3.87). Potential barriers included intervention complexity (mean = 3.47), needed human resources (mean = 2.71-3.33), and only slight agreement with relative advantage over existing screening/referral systems (mean = 3.09-3.71). Qualitative results (n = 15) identified low advantage for clinics with robust behavioral health systems but strong advantage in clinics without these services. Respondents identified system-wide training and monitoring strategies to facilitate implementation.

CONCLUSIONS

Ryan White Medical Case Management sites are a generally favorable context for the implementation of the interventions. As illustrated in an implementation research logic model, barriers will be addressed through deploying strategies proposed to impact clinic- and individual-level outcomes, including electronic prompts (reduce complexity), training on Optimizing Resilience and Coping with HIV through Internet Delivery as a complement to other behavioral health services (increase relative advantage), and feedback during implementation (strengthen rewards/incentives).

Protocol for an attention-matched randomized controlled trial of 2GETHER: a relationship education and HIV prevention program for young male couples

BACKGROUND

Young men who have sex with men (YMSM) are disproportionately impacted by the HIV epidemic in the USA, and a large number of new infections among YMSM occur in the context of main or primary partnerships. At the same time, healthy romantic relationships promote health and wellbeing by improving social support and encouraging healthy behaviors. Thus, we created 2GETHER: a relationship education and HIV prevention program for young male couples. 2GETHER is delivered face-to-face in a university setting and is composed of two group sessions and two individualized skills coaching sessions. We observed strong support of the feasibility, acceptability, and preliminary efficacy of 2GETHER in a pilot trial.

METHODS

We are conducting an attention-matched randomized controlled trial (RCT) to test the efficacy of 2GETHER relative to a control condition based on a well-validated positive affect enhancement program. Enrollment occurred between August 2017 and March 2021 in Chicago and surrounding areas, and we enrolled and randomized 128 dyads (N = 256 individuals). Follow-up is ongoing and we will examine primary and secondary behavioral outcomes at 12 months post-intervention, with interim follow-up at 3, 6, and 9 months post-intervention. The primary biomedical outcome is sexually transmitted infection incidence at a 12-month follow-up.

DISCUSSION

2GETHER is innovative in that it places an equal emphasis on relationship skill building and HIV prevention. Thus, the program has the potential to impact numerous health-related outcomes. Despite challenges related to the recruitment of couples and the COVID-19 pandemic, we were able to enroll a robust sample of young male couples with sufficient power to detect effects on study outcomes.

Finding Sunshine on a Cloudy Day: A Positive Affect Intervention for Co-Occurring Methamphetamine Use and HIV

Among sexual minority men (i.e., gay, bisexual, and other men who have sex with men) living with HIV, those who use methamphetamine experience profound health disparities. Affect Regulation Treatment to Enhance Methamphetamine Intervention Success (ARTEMIS) is an evidence-based, 5-session, individually delivered positive affect intervention adapted for sexual minority men living with HIV who use methamphetamine. ARTEMIS was designed to amplify the benefits of evidence-based substance use interventions such as contingency management (CM) with this high-priority population. Delivering ARTEMIS during CM has been shown to assist participants in reducing stimulant use, increasing positive affect, and achieving durable reductions in HIV viral load. We describe the theoretical underpinnings of the ARTEMIS intervention, provide details of the training and session protocols with a case example, and discuss implications for future applications in research and clinical settings.

The efficacy and mechanism of positive psychological intervention on well-being for colostomy patients: a randomized controlled trial

AIMS

The positive psychology intervention (PPI) is an effective therapy designed to motivate individuals' positive quality and power, to help them survive in an adverse situation, and to establish a high-quality personal and social life. This study aims to evaluate the efficacy and mechanism of PPI on the psychological capital, psychological distress, and life satisfaction among colostomy patients.

METHODS

Patients (n = 120) with permanent stomas were recruited and randomly assigned into two groups. Patients in the experimental group (n = 60) received standard care and PPI, whereas patients in the control group (n = 60) only received standard care. The psychological capital, psychological distress, and life satisfaction were measured and compared between two groups before the intervention, the immediate post-intervention, and follow-up.

RESULTS

All 120 patients completed the study. The hope, optimism, resilience, psychological distress, and life satisfaction score of the experimental group were significantly higher than those of the control group at T1 and T2 (P < 0.05). Self-efficacy score of the experimental group had no significant difference at the two time points after the intervention than the control group (P > 0.05). Changes in hope and resilience which belong to psychological capital mediated the intervention's efficacy on changes in PPI on life satisfaction (β = 0.265, P = 0.005; β = 0.686, P = 0.002).

CONCLUSIONS

PPI could effectively improve psychological capital, psychological distress, and life satisfaction among patients with stomas. Besides, our findings add novel support that increased hope and resilience are the active ingredients that promote intervention change.

Feature-level analysis of a smoking cessation smartphone app that uses a positive psychology approach (Preprint)

Background

Smoking cessation smartphone apps have emerged as highly accessible tools to support smoking cessation efforts. It is unknown how specific app features contribute to user engagement over time and relate to smoking outcomes.

Objective

To provide a feature-level analysis of the Smiling Instead of Smoking app (version 2) and to link feature use to subsequent smoking cessation.

Methods

Nondaily smokers (N=100) used the app for a period of 49 days (1 week before quitting and 6 weeks after quitting). Participants self-reported 30-day point-prevalence abstinence at the end of this period and at a 6-month follow up (the survey response rate was 94% and 89% at these points, respectively). Self-reported 30-day point prevalence abstinence rates were 40% at the end of treatment and 56% at the 6-month follow up. The app engaged users in both positive psychology content and traditional behavioral smoking cessation content. The app sent push notifications to prompt participants to complete prescribed content (ie, a “happiness exercise” every day and a “behavioral challenge” to use the app’s smoking cessation tools on 15 out of 49 days). Actions that participants took within the app were timestamped and recorded.

Results

Participants used the app on 24.7 (SD 13.8) days out of the 49 prescribed days, interacting with the happiness content on more days than the smoking content (23.8, SD 13.8 days vs 17.8, SD 10.3 days; t₉₉=9.28 [2-tailed]; P<.001). The prescribed content was frequently completed (45% of happiness exercises; 57% of behavioral challenges) and ad libitum tools were used on ≤7 days. Most participants used each ad libitum smoking cessation tool at least once, with higher use of personalized content (≥92% used “strategies,” “cigarette log,” “smoke alarms,” and “personal reasons”) than purely didactic content (79% viewed “benefits of quitting smoking”). The number of days participants used the app significantly predicted 30-day point-prevalence abstinence at the end of treatment (odds ratio [OR] 1.05, 95% CI 1.02-1.09; P=.002) and at the 6-month follow up (OR 1.04, 95% CI 1.008-1.07; P=.01). The number of days participants engaged with the happiness content significantly predicted smoking abstinence at the end of treatment (OR 1.05, 95% CI 1.02-1.08; P=.002) and at the 6-month follow up (OR 1.04, 95% CI 1.007-1.07; P=.02). This effect was not significant for the number of days participants engaged with the smoking cessation content of the app, either at the end of treatment (OR 1.04, 95% CI 0.996-1.08, P=.08) or at the 6-month follow up (OR 1.02, 95% CI 0.98-1.06; P=.29).

Conclusions

Greater app usage predicted greater odds of self-reported 30-day point-prevalence abstinence at both the end of treatment and over the long term, suggesting that the app had a therapeutic benefit. Positive psychology content and prescriptive clarity may promote sustained app engagement over time.

A phone and text message intervention to improve physical activity in midlife: initial feasibility testing

Background

Physical activity during midlife (ages 45-64) plays a major role in the prevention of chronic and serious medical conditions. Unfortunately, many midlife adults struggle to be physically active in the setting of low levels of psychological well-being and the management of multiple confluent sources of stress. Effective, scalable, midlife-specific interventions are needed to promote physical activity and prevent the development of chronic medical conditions.

Objectives

In an initial proof-of-concept trial, we assessed the feasibility and acceptability of a new, midlife-adapted, phone- and text message-based intervention using positive psychology (PP) skill-building and motivational interviewing (MI) techniques. We secondarily analyzed post-intervention changes in accelerometer-measured physical activity and self-reported outcomes.

Methods

The PP-MI intervention included six weekly phone sessions with a study trainer, with completion of PP activities and physical activity goals between calls, and in the subsequent six weeks briefer phone check-ins were conducted. Text messages over the 12-week intervention period were utilized to support participants and identify barriers to goal completion. Feasibility (session completion rates) and acceptability (participant ratings of intervention ease and utility) were assessed via descriptive statistics, and pre-post improvements in psychological, functional, and physical activity outcomes at 12 weeks were examined via mixed effects regression models.

Results

Twelve midlife adults with low baseline physical activity enrolled in the single-arm trial. Overall, 76.8% of all possible sessions were completed by participants, and mean ratings of weekly phone sessions were 8.9/10 (SD 1.6), exceeding our a priori thresholds for feasibility and acceptability. Participants demonstrated generally medium to large effect size magnitude improvements in accelerometer-measured physical activity, psychological outcomes, and function.

Conclusions

A novel, midlife-specific phone- and text-based PP-MI intervention was feasible and had promising effects on physical activity and other clinically relevant outcomes, supporting next-step testing of this program via a randomized controlled trial.

Pilot Randomized Controlled Trial of Motivational Interviewing with Sexual Minority Male Couples to Reduce Drug Use and Sexual Risk: The Couples Health Project

A randomized controlled trial evaluated the preliminary efficacy of a dyadically-delivered motivational interviewing (MI) intervention to reduce drug use and sexual risk in a sample of 50 sexual minority (cis)male (SMM) couples. In each couple, at least one partner was aged 18–29; reported drug use and sexual HIV transmission risk; and was HIV-negative. Couples were randomized to either the three-session MI intervention or an attention-matched control, with follow-up surveys completed at 3- and 6-months post-baseline. Between-group differences for all outcomes were non-significant in the overall sample. Subsequent moderation analyses indicated the intervention significantly reduced illicit drug use (excluding marijuana) at 3-month follow-up when either respondents (B = − 1.96; interval rate ratio—IRR 0.02–1.22; p = .001), their partners (B = − 2.60; IRR 0.01–0.64; p = .004), or both (B = − 2.38; IRR 0.01–0.80; p = .001) reported high levels of baseline use. The intervention also reduced condomless anal sex (CAS) with casual partners when both partners reported high frequency baseline CAS (B = − 2.54; IRR 0.01–0.83; p = .047). Findings provide initial evidence of the potential for MI to address drug use and sexual risk-taking among SMM couples at highest risk.

Responses to positive affect and unique resting-state connectivity in individuals at clinical high-risk for psychosis

Individuals at clinical high-risk for psychosis (CHR) report dampened positive affect, while this deficit appears to be an important clinical marker, our current understanding of underlying causes is limited. Dysfunctional regulatory strategies (i.e., abnormal use of dampening, self-focused, or emotion-focused strategies) may account for dampening affect but has not yet been examined. Participants (57 CHR and 56 healthy controls) completed the Response to Positive Affect Scale, clinical interviews, and resting-state scan examining nucleus accumbens (NAcc) connectivity. Individuals at CHR for psychosis showed greater dampening (but no differences in self/emotion-focus) in self-reported response to positive affect compared to healthy controls. In individuals at CHR, higher levels of dampening and lower levels of self-focus were associated with higher positive and lower negative symptoms. Dampening responses were related to decreased dorsal and rostral anterior cingulate cortex-NAcc resting-state connectivity in the CHR group but increased dorsal and rostral anterior cingulate cortex-NAcc resting-state connectivity in the healthy control group. Self-focused responses were related to increased dorsolateral prefrontal cortex-NAcc resting-state connectivity in the CHR group but decreased resting-state connectivity in the healthy control group. Self-reported dampening of positive affect was elevated in individuals at CHR for psychosis. Dampening and self-focused responses were associated with distinct resting-state connectivity compared to peers, suggesting unique mechanisms underlying these emotion regulation strategies. Responses to positive affect may be a useful target for cognitive treatment, but individuals at CHR show distinct neurocorrelates and may require a tailored approach.

Six-Week Online Multi-component Positive Psychology Intervention Improves Subjective Wellbeing in Young Adults

Improving mental wellbeing has a range of benefits for society, including increased productivity, longevity, and resiliency. However, interventions designed to improve mental wellbeing are often only compared to waitlist controls, leaving uncertainty regarding the mechanisms of their effectiveness. The current study in 326 participants assessed a six-week positive psychology intervention against an active control (n = 163) in an online randomized control trial. Outcome measures included life satisfaction, wellbeing (subjective and psychological wellbeing), stress, depression and anxiety symptoms, and self-compassion. The potential moderating effect of participating during the ongoing COVID-19 pandemic was also explored. The intervention group showed greater improvements in life satisfaction by week six (β = 0.18, p = .014) and were maintained through to 7 weeks post-baseline (β = 0.23, t = 3.07, p = .002) and remained significant when accounting for COVID-19 restrictions. An improvement in composite wellbeing from baseline to 7 weeks post-baseline was detected when accounting for COVID-19 restrictions. Composite wellbeing and total depression and anxiety symptoms improved significantly more in the intervention group for participants with low baseline resiliency resources. These findings support the efficacy of using online multi-component positive psychology interventions in boosting wellbeing and reducing distress symptoms particularly in individuals with fewer resiliency resources who may need added support.

Does positive affect mediate the association of multimorbidity on depressive symptoms?

Objectives Multimorbidity poses various challenges, and previous research has indicated a causal relation with depression. As multimorbidity is not curable, the underlying mechanisms are of great interest. Positive affect is a major resource for coping with chronic conditions and for the prevention of depression. Long-term multimorbidity, however, may deplete positive affect. The purpose of this paper is to investigate the role of positive affect in the association between multimorbidity and depressive symptoms.Method We used four consecutive waves (2008, 2011, 2014, 2017) of the nationally representative German Ageing Survey (DEAS) with a total of 1,558 older adults aged 40 and over. To account for time-varying confounding, exposure-induced mediator-outcome confounding, and reciprocities, we applied the mediational g-formula with inverse-probability weighting techniques. We also tested for exposure-mediator interaction to adjust for differences in mediation across the duration of multimorbidity.Results We confirmed a positive longitudinal relation between multimorbidity and depressive symptoms, both of which were negatively associated with while positive affect. The model without interaction indicated a share mediated of ca. 18.3% on the total effect of multimorbidity on depressive symptoms. Addition of interaction led to substantial differences for multimorbidity duration and levels of positive affect. Associations for long-term multimorbidity (at least two survey waves) were more substantial, and the share mediated doubled (>40%). Additionally, the direct effect of multimorbidity on depressive symptoms diminished for short-term multimorbidity.Conclusion Strengthening positive affect could reduce depressive symptoms in those facing multimorbidity. This study also discusses methodological challenges in performing longitudinal mediation analysis. We advise researchers to consider the mediational g-formula and exposure-mediator interaction.

Psychological wellbeing and the association with burnout in a cohort of healthcare workers during the COVID-19 pandemic

Burnout, depression, and anxiety are prevalent among healthcare workers (HCWs) during the COVID-19 pandemic and have been previously shown to contribute to poor health outcomes and reduced quality of care. Positive psychological constructs such as positive affect and meaning and purpose are related to resilience in the face of significant stress. No studies have examined these associations among a cohort of HCWs during this pandemic. The purpose of this study was to examine the association of depression, anxiety, positive affect, and meaning and purpose with burnout among HCWs during the COVID-19 pandemic. We utilized data from a cross-sectional survey conducted between September 29-December 8, 2021, among a cohort of 2,411 HCWs from a large, tertiary academic health care system in the Chicago area. We employed the Patient-Reported Outcomes Measurement Information System (PROMIS) measures for depression, anxiety, positive affect, and meaning and purpose and burnout was measured by the Oldenburg Burnout Inventory (OLBI). The majority (80.88%) of HCWs in this study identified as White, Non-Hispanic race/ethnicity, female sex (82.37%), and roughly one third were between ages 30-39 years old (30.98%). Registered nurses (26.96%) accounted for the largest single occupation group. The mean burnout score was 36.87 (SD = 7.65), with 53.38% of participants classified as having burnout, and registered nurses demonstrating the highest proportions of burnout (63.54%). Higher depression (coef = 0.15, SE = 0.03, p < 0.001) and anxiety (coef = 0.25, SE = 0.02, p < 0.001) scores were associated with higher burnout in multivariable linear regression models. Increased positive affect (coef= -0.19, SE= 0.02, p < 0.001) and meaning and purpose (coef= -0.12, SE= 0.01, p < 0.001) scores were significantly associated with reduced burnout. Positive affect and meaning and purpose were inversely associated with burnout among a cohort of HCWs during the COVID-19 pandemic. Previous studies of positive affect and meaning and purpose suggest the potential buffering effect that these indices may have on burnout. Future research is needed to examine the effect of positive affect and meaning and purpose on mitigating the negative impacts of burnout, depression, and anxiety among HCWs as they cope with the stress of the COVID-19 pandemic and beyond.

A Smoking Cessation App for Nondaily Smokers (Version 2 of the Smiling Instead of Smoking App): Acceptability and Feasibility Study

Background

Recent evidence highlights the significant detrimental impact of nondaily smoking on health and its disproportionate prevalence in underserved populations; however, little work has been done to develop treatments specifically geared toward quitting nondaily smoking.

Objective

This study aims to test the feasibility, acceptability, and conceptual underpinnings of version 2 of the Smiling Instead of Smoking (SiS2) smartphone app, which was developed specifically for nondaily smokers and uses a positive psychology approach.

Methods

In a prospective, single-group study, nondaily smokers (N=100) were prescribed use of the SiS2 app for 7 weeks while undergoing a quit attempt. The app assigned daily positive psychology exercises and behavioral tasks every 2 to 3 days, which guided smokers through using the smoking cessation tools offered in the app. Participants answered surveys at baseline and at 2, 6, 12, and 24 weeks postquit. Feasibility was evaluated based on app use and acceptability based on survey responses. The underlying conceptual framework was tested by examining whether theorized within-person changes occurred from baseline to end of treatment on scales measuring self-efficacy, desire to smoke, and processing of self-relevant health information (ie, pros and cons of smoking, importance of the pros and cons of quitting, and motivation).

Results

Participants used the SiS2 app on an average of 24.7 (SD 13.8) days out of the 49 prescribed days. At the end of treatment, most participants rated the functions of the app as very easy to use (eg, 70/95, 74% regarding cigarette log and 59/95, 62% regarding happiness exercises). The average score on the System Usability Scale was 79.8 (SD 17.3; A grade; A+ ≥84.1, B+ <78.8). Most participants reported that the app helped them in their quit attempt (83/95, 87%), and helped them stay positive while quitting (78/95, 82%). Large effects were found for within-person decreases in the desire to smoke (b=−1.5, 95% CI −1.9 to −1.1; P<.001; g_av=1.01), the importance of the pros of smoking (b=-20.7, 95% CI −27.2 to −14.3; P<.001; g_av=0.83), and perceived psychoactive benefits of smoking (b=−0.8, 95% CI −1.0 to −0.5; P<.001; g_av=0.80). Medium effects were found for increases in self-efficacy for remaining abstinent when encountering internal (b=13.1, 95% CI 7.6 to 18.7; P<.001; g_av=0.53) and external (b=11.2, 95% CI 6.1 to 16.1; P<.001; g_av=0.49) smoking cues. Smaller effects, contrary to expectations, were found for decreases in motivation to quit smoking (P=.005) and the perceived importance of the pros of quitting (P=.009). Self-reported 30-day point prevalence abstinence rates were 40%, 56%, and 56% at 6, 12, and 24 weeks after the quit day, respectively.

Conclusions

The SiS2 app was feasible and acceptable, showed promising changes in constructs relevant to smoking cessation, and had high self-reported quit rates by nondaily smokers. The SiS2 app warrants testing in a randomized controlled trial.

Positive Psychological Factors and Life Themes in Relation to Health Outcomes in Women Living with HIV

BACKGROUND

This mixed methods study identified positive psychological factors and life themes expressed in autobiographical narratives of predominantly Black women living with HIV (WLWH) and investigated these in relation to depressive symptoms, antiretroviral therapy (ART) adherence (≥ 95% of time), and undetectable HIV viral load (VL) (< 80 copies/ml).

METHOD

Ninety-eight WLWH from the Women's Interagency HIV Study Chicago site (M age = 45.3; 91% Black) narrated three autobiographical life turning points, reliably coded for positive factors and life themes. ART adherence, VL and depressive symptoms, assessed with Center for Epidemiologic Studies Depression Scale total score (TOT) including its four factors (negative affect (NA), positive affect (PA), somatic symptoms (SS), and interpersonal problems (IP)), were collected over two time points: concurrently with narratives and 6 months later. Composite scores across the two time points were used in all analyses.

RESULTS

Ten positive psychological factors (gratitude, insight, compassion, meaning-making, acceptance, mindfulness, generativity, optimism, self-reliance, and benevolent God beliefs) and three positive life themes (health improvements, positive relationships, and accomplishments) were identified in narratives. Higher accomplishments, overall positive factors, insight, mindfulness, self-reliance, optimism, meaning-making, and acceptance related to lower depressive symptoms (TOT, NA, SS, or IP). Positive factors and life themes did not significantly relate to PA. Higher compassion related to higher ART adherence. Higher accomplishments related to undetectable VL independent of ART adherence.

CONCLUSION

Findings that positive psychological factors and life accomplishments may relate to better health, especially to lower depression, potentially contribute to developing positive psychology interventions for Black WLWH.

Applying theoretical models of positive emotion to improve pediatric asthma: A positive psychology approach

Positive emotion, encompassing feelings such as joy and happiness, has been shown to predict a multitude of health outcomes. However, the role of positive emotion in pediatric asthma is not understood. No work to date has examined how positive emotion may offer benefits to children and adolescents with asthma. Based on theory and models of positive emotion and health, we hypothesize that positive emotion may improve asthma outcomes through mediators such as health behaviors and health-relevant physiological functioning. Moreover, boosting positive emotion during times of stress may be particularly relevant in mitigating asthma symptoms. In the present commentary, we elaborate on the hypothesized mechanisms behind such associations grounded within positive emotion theoretical frameworks. Additionally, we summarize the methodologically rigorous work of positive emotion interventions in other clinical settings to propose that positive emotion could be a useful tool in the management of pediatric asthma.

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.

Effectiveness of a brief positive skills intervention to improve psychological adjustment in patients with end-stage kidney disease newly initiated on haemodialysis: protocol for a randomised controlled trial (HED-Start)

INTRODUCTION

Initiation onto haemodialysis is a critical transition that entails multiple psychosocial and behavioural demands that can compound mental health burden. Interventions guided by self-management and cognitive-behavioural therapy to improve distress have been variably effective yet are resource-intensive or delivered reactively. Interventions with a focus on positive affect for patients with end-stage kidney disease are lacking. This study will seek (1) to develop a positive life skills intervention (HED-Start) combining evidence and stakeholder/user involvement and (2) evaluate the effectiveness of HED-Start to facilitate positive life skills acquisition and improve symptoms of distress and adjustment in incident haemodialysis patients.

METHODS AND ANALYSIS

This is a single/assessor-blinded randomised controlled trial (RCT) to compare HED-Start to usual care. In designing HED-Start, semistructured interviews, a codesign workshop and an internal pilot will be undertaken, followed by a two-arm parallel RCT to evaluate the effectiveness of HED-Start. A total of 148 incident HD patients will be randomised using a 1:2 ratio into usual care versus HED-Start to be delivered in groups by trained facilitators between January 2021 and September 2022. Anxiety and depression will be the primary outcomes; secondary outcomes will be positive and negative affect, quality of life, illness perceptions, self-efficacy, self-management skills, benefit finding and resilience. Assessments will be taken at 2 weeks prerandomisation (baseline) and 3 months postrandomisation (2 weeks post-HED-Start completion). Primary analyses will use an intention-to-treat approach and compare changes in outcomes from baseline to follow-up relative to the control group using mixed-effect models.

ETHICS AND DISSEMINATION

Ethics approval was obtained from Nanyang Technological University Institutional Review Board (IRB-2019-01-010). Written informed consent will be obtained before any research activities. Trial results will be disseminated via publications in peer-reviewed journals and conference presentations and will inform revision(s) in renal health services to support the transition of new patients to haemodialysis.

Interview-Rated Meaning and Survival Over 17 Years in People Living With HIV

OBJECTIVE

The primary purpose of this study was to determine whether meaning in life predicts survival in people living with HIV (PLWH) over 17 years. This study also examined whether interviewer- and transcript-rated meanings predict survival equivalently. A third purpose of the study was to investigate whether meaning in life adds to the prediction of survival over positive emotional expression.

METHODS

A diverse sample of people with HIV (n = 177) completed an interview on stress and coping at baseline and were followed up for survival up to 17 years. Meaning was measured by interviewer rating of four items (meaningful purpose, unfinished business, finding new meaning, and meaningful activities). Transcript-rated meaning was assessed by two independent raters. Cox proportional hazards regression was used to determine whether meaning predicted survival over 17 years.

RESULTS

Meaning in life predicted significantly greater survival, adjusting for biomedical and sociodemographic variables whether assessed by interviewer or by transcript raters. Hazard ratios suggest that the effect is moderate to large (2.66-3.45 for top versus bottom third; 2.05-2.49 for top versus bottom half). Significance was maintained after adjusting for positive emotion.

CONCLUSIONS

Meaning assessed by interview (by both interviewer and transcript ratings) predicted greater survival over 17 years in PLWH and did so above positive emotion. This adds to a literature that is primarily based on self-report questionnaires. Meaning may have beneficial effects for both psychological and physical health in PLWH.

An autoregressive cross-lagged model unraveling co-occurring stimulant use and HIV: Results from a randomized controlled trial

BACKGROUND

Evidence-based interventions are needed to address the use of stimulants such as methamphetamine as a driver of onward HIV transmission and faster clinical HIV progression among sexual minority men. Prior randomized controlled trials with people living with HIV who use substances indicate that financial incentives provided during contingency management (CM) are effective for achieving short-term reductions in stimulant use and HIV viral load. However, the benefits of CM are often not maintained after financial incentives for behavior change end.

PURPOSE

Data from a recently completed randomized controlled trial with 110 sexual minority men living with HIV who use methamphetamine was leveraged to examine mediators of the efficacy of a positive affect intervention for extending the benefits of CM.

METHODS

An autoregressive cross-lagged model was fit to determine if reductions in HIV viral load were mediated by intervention-related increases in positive affect and decreases in stimulant use measured in four waves over 15 months.

RESULTS

Higher baseline positive affect predicted significantly lower self-reported stimulant use immediately following the 3-month CM intervention period, even after controlling for self-reported stimulant use at baseline. Moreover, decreased stimulant use emerged as an independent predictor of long-term reductions HIV viral load at 15 months, even after adjusting for HIV viral load at baseline and the residual effect of the positive affect intervention.

CONCLUSIONS

Findings underscore the importance of durable reductions in stimulant use as a primary intervention target that is essential for optimizing the clinical and public health benefits of HIV treatment as prevention.

Sleep and stress in times of the COVID-19 pandemic: The role of personal resources

There is still little research on the association between COVID-19-related stress and insufficient sleep. As distress is assumed to be high in these times, the role of personal resources becomes more important. The current study aimed to investigate the predictive role of COVID-19-related stress, positive affect, and self-care behavior for subjective sleep quality and sleep change measures since the outbreak of COVID-19 in Germany. A sample of 991 adults (M = 34.11 years; SD = 12.99) answered questionnaires during the first lockdown period in Germany and afterward (between April 1 and June 5, 2020). A higher stress level predicted lower sleep quality and more negative changes in overall sleep and pre-sleep arousal. Higher levels of positive affect and self-care predicted higher sleep quality and more positive changes in sleep. Analyses showed a moderation of positive affect on the association between stress and change in pre-sleep arousal. The improvement in personal resources, especially positive affect, in times of high stress seems relevant to overcome sleep problems. Future research should include objective measurements of sleep and longitudinal designs to uncover causal directions of effects.

Feasibility and Acceptability of a Program to Promote Positive Affect, Well-Being and Gender Empowerment in Black Women Living with HIV

While programs and interventions intended to increase positive affect among people living with HIV (PLWH) and other chronic diseases have been associated with improved health outcomes, including decreased depression, programs have not been tailored specifically for Black women. We tailored a program designed to increase positive affect and to decrease depressive symptoms in PLWH to a group format for Black WLWH. We also added skills to increase gender empowerment. We then tested the acceptability and feasibility of this program with 8 Black WLWH. The program was acceptable and relatively feasible, as assessed by women’s participation and feedback about program clarity and helpfulness, which women rated above 9 on a 10-point scale. A few women suggested that optimal delivery point for some skills taught would be shortly after HIV diagnosis. A proof-of-concept program intended to bolster positive emotions and gender empowerment and decrease depression can be tailored for Black WLWH and is relatively feasible and acceptable. A randomized controlled trial is needed to assess the preliminary efficacy of this program on positive affect, depression, and other health outcomes for WLWH.

Positive Emotion Skills Intervention to Address Burnout in Critical Care Nurses

Critical care nurses experience high levels of workplace stress, which can lead to burnout. Many medical centers have begun offering wellness programs to address burnout in their nursing staff; however, most of these programs focus on reducing negative states such as stress, depression, and anxiety. A growing body of evidence highlights the unique, independent role of positive emotion in promoting adaptive coping in the face of stress. This article describes a novel approach for preventing burnout in critical care nurses: an intervention that explicitly aims to increase positive emotion by teaching individuals empirically supported skills. This positive emotion skills intervention has been used successfully in other populations and can be tailored for critical care nurses. Also discussed are recommendations for addressing burnout in intensive care unit nurses at both the individual and organizational levels.

A systematic review and meta-analysis of psychological interventions to improve mental wellbeing

Our current understanding of the efficacy of psychological interventions in improving mental states of wellbeing is incomplete. This study aimed to overcome limitations of previous reviews by examining the efficacy of distinct types of psychological interventions, irrespective of their theoretical underpinning, and the impact of various moderators, in a unified systematic review and meta-analysis. Four-hundred-and-nineteen randomized controlled trials from clinical and non-clinical populations (n = 53,288) were identified for inclusion. Mindfulness-based and multi-component positive psychological interventions demonstrated the greatest efficacy in both clinical and non-clinical populations. Meta-analyses also found that singular positive psychological interventions, cognitive and behavioural therapy-based, acceptance and commitment therapy-based, and reminiscence interventions were impactful. Effect sizes were moderate at best, but differed according to target population and moderator, most notably intervention intensity. The evidence quality was generally low to moderate. While the evidence requires further advancement, the review provides insight into how psychological interventions can be designed to improve mental wellbeing.

Daily emotional inertia and long-term subjective well-being among people living with HIV

OBJECTIVE

The aim of this study was to verify if subjective well-being (SWB) modifies the autoregressive effect of daily emotions and if this emotional inertia predicts long-term changes in SWB among people living with HIV (PLWH).

METHODS

The 131 participants had medically confirmed diagnoses of HIV and were undergoing antiretroviral therapy. They assessed their SWB (satisfaction with life, negative affect, positive affect) twice with an interval of one year. They also took part in a five-day online diary study six months from their baseline SWB assessment and reported their daily negative and positive emotions.

RESULTS

Results showed that baseline SWB did not modify the emotional carryover effect from one to another. Additionally, after control for baseline SWB, emotional inertia did not predict SWB one year later. However, such an effect was noted for the mean values of daily reported emotions, indicating their unique predictive power over SWB itself.

CONCLUSIONS

This may suggest that emotional inertia does not necessarily provide better information than more straightforward measures of affective functioning.

Subjective Well-Being, Depression, and Delays in Care Among Older Adults: Dual-Eligible Versus Medicare-Only Beneficiaries

We aimed to (a) determine the role of subjective well-being and depression in care delays among Medicare beneficiaries and (b) examine whether subjective well-being and depression play a differential role among Medicare-only and dual-eligible beneficiaries. A nationally representative sample of 1,696 older adults participated in the study. Roughly, 22% of participants reported often or sometimes experiencing care delays, with more delays among dual eligibles. We found that higher levels of subjective well-being were significantly related to less frequent care delays. In contrast, higher levels of depression were significantly related to more frequent care delays. Moreover, as depression increased, the predicted probability of delays increased to a greater extent among dual eligibles than Medicare-only beneficiaries. These findings signify the importance of identifying and implementing strategies to enhance subjective well-being and reduce depression in older adults, particularly dual eligibles, to improve access to timely care.

Development of a Positive Psychology Program (LAVENDER) for Preserving Medical Student Well-being: A Single-Arm Pilot Study

Background

Mental health tends to worsen over the course of medical school, with steep declines in well-being in students' clerkship year (M3). Positive emotion promotes adaptive coping to stress and may help preserve medical student well-being.

Objective

This study describes the development of LAVENDER (Leveraging Affect and Valuing Empathy for Nurturing Doctors' Emotional Resilience), a program aimed at increasing positive emotion to preserve well-being in medical students.

Methods

We conducted a single-arm pilot of LAVENDER, a positive psychology intervention developed for medical students delivered in an interactive classroom format to a cohort of 157 third-year medical students at the Albert Einstein College of Medicine. Our primary outcome was the acceptability of LAVENDER. We also examined preliminary efficacy using measures of emotion, stress and burnout collected at each intervention session.

Results

LAVENDER showed good acceptability: 76% of participants agreed that the LAVENDER skills were useful and 72% agreed that they would recommend the LAVENDER program to others. Qualitative feedback suggested that medical students enjoyed the program and found the skills to be useful for coping with stress, but also reported the following barriers to engagement: lack of time to practice the skills, resistance to the mandatory nature of the wellness sessions, and difficulty integrating the skills in daily life. We did not find support for the preliminary efficacy of LAVENDER for improving medical student well-being in students' clerkship year. Participants showed decreases in positive emotion and increases in symptoms of burnout over the intervention period (ps < .01).

Conclusion

The current paper describes the development and a single-arm pilot test of LAVENDER, a positive psychology program tailored for medical students. Although we found preliminary evidence for the acceptability of LAVENDER, we did not find support for the preliminary efficacy. Lessons learned and next steps for the program are discussed.
