A Positive Psychology Intervention in Allogeneic Hematopoietic Stem Cell Transplantation Survivors (PATH): A Pilot Randomized Clinical Trial.

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (HSCT) survivors experience significant psychological distress and low levels of positive psychological well-being, which can undermine patient-reported outcomes (PROs), such as quality of life (QoL). Hence, we conducted a pilot randomized clinical trial to assess the feasibility and preliminary efficacy of a telephone-delivered positive psychology intervention (Positive Affect for the Transplantation of Hematopoietic stem cells intervention [PATH]) for improving well-being in HSCT survivors. METHODS: HSCT survivors who were 100 days post-HSCT for hematologic malignancy at an academic institution were randomly assigned to either PATH or usual care. PATH, delivered by a behavioral health expert, entailed 9 weekly phone sessions on gratitude, personal strengths, and meaning. We defined feasibility a priori as >60% of eligible participants enrolling in the study and >75% of PATH participants completing ≥6 of 9 sessions. At baseline and 9 and 18 weeks, patients self-reported gratitude, positive affect, life satisfaction, optimism, anxiety, depression, posttraumatic stress disorder (PTSD), QoL, physical function, and fatigue. We used repeated measures regression models and estimates of effect size (Cohen's d) to explore the preliminary effects of PATH on outcomes. RESULTS: We enrolled 68.6% (72/105) of eligible patients (mean age, 57 years; 50% female). Of those randomized to PATH, 91% completed all sessions and reported positive psychology exercises as easy to complete and subjectively useful. Compared with usual care, PATH participants reported greater improvements in gratitude (ß = 1.38; d = 0.32), anxiety (ß = -1.43; d = -0.40), and physical function (ß = 2.15; d = 0.23) at 9 weeks and gratitude (ß = 0.97; d = 0.22), positive affect (ß = 2.02; d = 0.27), life satisfaction (ß = 1.82; d = 0.24), optimism (ß = 2.70; d = 0.49), anxiety (ß = -1.62; d = -0.46), depression (ß = -1.04; d = -0.33), PTSD (ß = -2.50; d = -0.29), QoL (ß = 7.70; d = 0.41), physical function (ß = 5.21; d = 0.56), and fatigue (ß = -2.54; d = -0.33) at 18 weeks. CONCLUSIONS: PATH is feasible, with promising signals for improving psychological well-being, QoL, physical function, and fatigue in HSCT survivors. Future multisite trials that investigate PATH's efficacy are needed to establish its effects on PROs in this population.

Effectiveness of a positive psychology and mindfulness-based app on mental health for parents of children with a neurodevelopmental disorder: study protocol of a pragmatic international randomized controlled trial.

INTRODUCTION: Parents of children with a neurodevelopmental disorder (NDD) experience more stress than parents of typically developing children. In a cocreation process with experts and parents, a low-threshold application that uses exercises based on the principles of positive psychology and mindfulness was developed. This application, called "Adappt," aims at enhancing the ability to adapt of the parents and caregivers of children with NDDs and at supporting their mental health. This protocol describes the evaluation study of the effectiveness of Adappt, its core working mechanisms and user experiences. METHOD: A pragmatic international multicenter randomized controlled trial will compare the effectiveness of Adappt with a (delayed) waitlist control condition. At least 212 parents or primary caregivers of children younger than 18 years diagnosed with or suspected of a NDD will be randomly assigned to the intervention or waitlist control condition. Participants are excluded if they have severe anxiety or depression levels or are in treatment for mental health issues. Measures will be collected online at baseline, post-intervention (1 month after baseline), and 4 and 7 months after baseline. The primary outcome is the improvement in generic sense of ability to adapt as measured with the Generic Sense of Ability to Adapt Scale (GSAAS; (Front Psychol 14:985408, 2023)) at 4-month follow-up. Secondary outcomes are mental well-being, (parental) distress, and client satisfaction with "Adappt." DISCUSSION: Results of this study will contribute to knowledge on the effectiveness of a low-threshold application for parents of children with a NDD in multiple countries. If the application is found to be effective in improving mental health, recommendations will be made for implementation in health care. TRIAL REGISTRATION: This study is registered on clinicaltrials.gov (NCT06248762) on February 8, 2024, and the Open Science Framework ( https://osf.io/5znqv ).

The impact of positive psychology counseling on sexual and marital satisfaction and anxiety among reproductive-aged women during the COVID-19 pandemic: a randomized controlled clinical trial.

BACKGROUND: Sexual and marital satisfaction is considered one of the important factors in happiness and life satisfaction of couples. COVID-19 pandemic results in psychological effects, such as increased anxiety levels which can affect sexual and marital satisfaction. This study aimed to investigate the impact of positive psychology on women's sexual and marital satisfaction. METHODS: A randomized controlled trial was conducted on 72 married women of reproductive age in Tabriz, Iran between February 2021 and May 2022. The participants were randomly divided into the intervention and control groups. There was no significant difference between the control and intervention groups in terms of the socio-demographic characteristics (p < 0.05). The mean age of the participants in the intervention and control groups was 31.8 ± 6.92 and 30.97 ± 5.09 years, respectively. The intervention group attended seven 60-90 min counseling sessions at weekly intervals. The Spielberger anxiety, sexual satisfaction and marital satisfaction questionnaires were completed before and four weeks after the intervention. RESULTS: The results of this study indicated that after counseling, the average overall score of marital satisfaction [MD: 15.46, 95% CI: 7.47 to 23.41, p = 0.034] and sexual satisfaction [MD: 7.83, 95% CI: 6.25 to 9.41, p = 0.001] significantly increased in the intervention group compared to the control group. Also, the mean score of state anxiety [MD: -2.50, 95% CI: -4.19 to -0.80, p = 0.001] and trait anxiety [MD: -1.03, 95% CI: -2.46 to -0.09, p = 0.032] significantly decreased after counseling in the intervention group compared to the control group. CONCLUSIONS: Using counseling based on a positive psychology approach can improve anxiety, sexual and marital satisfaction, and anxiety of women of reproductive age during the COVID-19 pandemic. However, further randomized clinical trials are needed before making a definitive conclusion. TRIAL REGISTRATION: Iranian Registry of Clinical Trials (IRCT): IRCT20171007036615N8.

Effects of gratitude intervention on mental health and well-being among workers: A systematic review.

OBJECTIVES: Gratitude intervention, which requires participants to engage regularly in brief activities designed to cultivate a sense of gratefulness, is known as one of the most effective positive psychological interventions. Although numerous meta-analyses and systematic reviews have been conducted on gratitude intervention, no studies have focused on the working population. This study aimed to systematically summarize the effectiveness of gratitude interventions on workers' mental health and well-being. METHODS: Systematic search was conducted in February 2021 using five databases. Eligible studies included randomized controlled trials implementing gratitude activities among healthy workers and measuring mental health or well-being indicators and original articles or thesis in English. RESULTS: Nine out of 1957 articles met the inclusion criteria. Eight studies adopted gratitude list interventions, showing a significant improvement in perceived stress and depression; however, the effects on well-being were inconsistent. Interventions with gratitude list four times or less did not report significant changes in any outcomes. CONCLUSIONS: Most gratitude interventions incorporated a gratitude list, and some studies included gratitude activities as a part of the combined program. On the other hand, no studies focused on only behavioral gratitude expression among workers. Gratitude interventions might be effective in improving mental health, but their effects on well-being remain unclear. The total number of gratitude lists and reflections might influence the effect on mental health and well-being; however, due to the high heterogeneity of the studies, further studies are needed.

Empirical validation of the psychological concept of a perceived feeling of 'energy': Advancement into the study of positive psychology.

The paradigm of positive psychology, significant in nature, helps to explain the proactivity and motivation of human agency, such as a secondary school student's state of autonomy, confidence, and personal resolve to strive for optimal learning and/or non-learning experiences. Our recent research development, in tandem with other scholars' inquiries, has focused on one aspect of positive psychology-namely, a person's achievement of 'optimal best', which reflects the maximization of his/her state of functioning (e.g., cognitive functioning). Capitalizing on our previous research, we develop a psychological concept that we term as a 'perceived feeling of energy'. A perceived feeling of energy (e.g., a perceived feeling of liveliness) is proposed to act as a 'motivational engine', or as a central driver, which then could predict and enhance a person's achievement of optimal best. Six hundred and twenty-seven university students (N = 438 women, 189 men) responded to a suite of self-report questionnaires. Structural equation modelling (SEM) techniques were used to test a conceptual model, where we focused on the antecedent (i.e., the direct impact of self-efficacy on a perceived feeling of energy) and consequence of a perceived feeling energy (i.e., the impact of a perceived feeling of energy on personal resolve, and the sustaining of optimal best). Analysis of results showed support for our original hypothesized model-for example: self-efficacy as an antecedent of energy and the central role of the energy as a predictor and potential mediator of future outcomes.

Design and evaluation of a positive intervention to cultivate mental health: preliminary findings

Abstract The past two decades have witnessed a proliferation of positive psychological interventions for clinical and nonclinical populations, and recent research, including meta-analyses, is providing evidence of its effectiveness. Most interventions have focused on increasing life satisfaction, positive affect, and psychological well-being. Manualized, multi-component interventions based on a comprehensive theory are scarce. Keyes' concept of mental health and flourishing (subjective, psychological, and social well-being) is an overarching theoretical framework to guide the design of a multi-component psychological intervention to cultivate well-being and personal development. Therefore, the purpose of this study was to design a theory-driven positive intervention and to pilot test the intervention. The manual presents an 8-week group program that includes homework activities. A sample of 56 young adults completed the intervention. Participants were assessed at base line, after termination, and at a 6-month follow-up session. Standardized instruments were used to assess the dimensions of mental health proposed by Keyes. Pre- and post-test measures of subjective, psychological, and social well-being showed significant differences, as did the total mental health scores. At 6-month follow-up, differences remained in subjective and psychological well-being and in positive mental health, with smaller effect sizes. Limitations of these preliminary findings as well as future lines of research and improvements in this manualized intervention are proposed in the light of current research on positive interventions.

Feasibility and preliminary efficacy of a positive psychology-based intervention to promote health behaviors in heart failure: The REACH for Health study.

OBJECTIVE: Most patients with heart failure (HF) struggle to adhere to health behaviors, and existing health behavior interventions have significant limitations. We developed a 12-week, phone-delivered, combined positive psychology (PP) and motivational interviewing (MI) intervention to promote well-being and adherence to physical activity, diet, and medications. In this three-arm, randomized trial, we assessed the feasibility, acceptability, and preliminary efficacy of the intervention compared to treatment as usual and MI-alone conditions in 45 patients with HF and suboptimal health behavior adherence. METHODS: Participants in the PP-MI or MI-alone conditions completed weekly phone sessions for 12 weeks. Those in PP-MI completed weekly PP exercises and set health behavior goals, while those in the MI-alone condition learned about HF-specific health behaviors and identified potential behavior changes. Primary study outcomes were feasibility (sessions completed) and acceptability (0-10 ratings of PP exercise ease and utility). The intervention's impact on psychological and behavioral outcomes was assessed using mixed effects regression analyses. RESULTS: Participants in the PP-MI condition completed 73% of sessions and rated PP exercises as easy to complete (mean = 7.5 [SD 1.7] out of 10) and subjectively useful (mean = 7.5 [SD 1.6] out of 10). Compared to the control conditions, PP-MI led to medium effect-size improvements in positive affect (Cohen's d = 0.32-0.77), moderate to vigorous physical activity (d = 0.41-0.74), and medication adherence (d = 0.48-0.78). CONCLUSION: This PP-MI intervention was feasible, well-accepted, and associated with promising improvements in well-being and health behavior outcomes. Larger trials are needed to examine this intervention's impact on health behavior adherence and other important outcomes (NCT03220204).

Association of Positive Affect Instability With All-Cause Mortality in Older Adults in England.

Importance: There is increasing recognition that positive affective states have a protective association for all-cause mortality. However, positive states of happiness and excitement vary over time, and little is known about the association of fluctuations in positive affect with survival. Objective: To investigate the association of positive affect instability, conceptualized as fluctuations in momentary positive affect, with mortality in a population-based sample of older adults in England. Design, Setting, and Participants: This survey study used data from a longitudinal survey collected in wave 2 (2004) of the English Longitudinal Study of Ageing, a nationally representative sample of older men and women living in England, with follow-up continuing until March 2018. Participants included people aged 50 years or older at recruitment. Data were analyzed from September 2019 to April 2020. Main Outcomes and Measures: The main outcome was all-cause mortality. Positive and negative affect were measured at 4 time points over the course of 1 day: soon after waking, 30 minutes after waking, at 7:00 pm, and at bedtime. Results: Data were analyzed from 3834 participants (mean [SD] age at baseline, 64.0 [7.4] years; 2082 [54.3%] women) with a mean (SD) follow-up of 12.25 (2.60) years. Adjusting for demographic characteristics, baseline illness, health behaviors, and mean level and instability in negative affect, Cox proportional hazards regression showed that high positive affect instability was associated with greater mortality, with a hazard ratio of 1.25 (95% CI, 1.04-1.49; P = .02). Associations did not differ by age, suggesting that the increased mortality risk associated with high positive affect instability was not restricted to older ages. Conclusion and Relevance: These findings suggest that temporal fluctuations in positive affect were associated with mortality risk in older adults. These findings illustrate the value of incorporating dynamic assessments of positive affect in distal health outcomes such as mortality.

Effects of a Community-Based Multicomponent Positive Psychology Intervention on Mental Health of Rural Adults in Ghana.

BACKGROUND: There is growing evidence that positive psychology interventions (PPIs) enhance positive mental health and lead to a decrease in symptoms of psychopathology. This study examines the effectiveness of a 10-week multicomponent PPI (the Inspired Life Program; ILP) in promoting positive mental health and reducing symptoms of depression and negative affect in a sample of rural poor adults in Ghana. METHODS: Using a quasi-randomized controlled trial design, participants from four rural poor communities were randomly allocated to intervention (n = 40) or control (n = 42) conditions. The intervention group participated in the 10-week ILP. Both groups completed a battery of mental health measures, including the Mental Health Continuum-Short Form, at pre-intervention, immediately after the intervention, and at 3 months follow-up. Hierarchical linear modeling was applied to evaluate whether the intervention was effective. RESULTS: There was a greater improvement in positive mental health, with a marked reduction in symptoms of depression in the intervention group compared to the control group, immediately and 3 months after the intervention. There were also larger increases in the proportion of flourishers in the intervention group compared to the control group, immediately and three months after the intervention. CONCLUSIONS: The observed effects of the ILP intervention program suggest that group-based PPIs can promote positive mental health and buffer against psychopathology among people living in rural poor communities in sub-Saharan Africa.

The long and winding road to happiness: A randomized controlled trial and cost-effectiveness analysis of a positive psychology intervention for lonely people with health problems and a low socio-economic status.

BACKGROUND: Our objective was to evaluate the effectiveness and cost-effectiveness of the positive psychology intervention 'Happiness Route' compared to an active control condition in a vulnerable population with an accumulation of health and psychosocial problems. METHODS: We conducted a randomized, single-blind, actively-controlled, parallel group study in seven municipalities in the Netherlands. To be eligible, participants had to experience loneliness, health problems and low socio-economic status. Each group received several home visits by a counsellor (two in the control condition, two to six in the experimental condition). In the Happiness Route, a happiness-based approach was used, whereas the control condition used a traditional problem-based approach. The primary outcome was well-being, measured with the Mental Health Continuum-Short Form (MHC-SF). RESULTS: Fifty-eight participants were randomized to the Happiness Route, 50 to the control condition. Participants were severely lonely, had on average three health problems and less than 5% had paid work. The total MHC-SF score, emotional and social well-being, depression and loneliness improved significantly over the nine-month period in both conditions (p < .05), but there were no significant changes between the conditions across time. Languishing decreased significantly from 33% at baseline to 16% at follow-up among the Happiness Route participants but did not change significantly in the control condition. No significant improvement over time was found in psychological well-being, resilience, purpose in life, health-related quality of life and social participation. Cost-effectiveness analysis showed that expected saved costs per QALY lost was €219,948 for the Happiness Route, relative to the control condition. The probability was 83% that the Happiness Route was cost saving and 54% that the Happiness Route was cost-effective at a willingness to accept a threshold of €100,000. CONCLUSIONS: Mental health status of both groups improved considerably. However, we could not demonstrate that the Happiness Route yielded better health outcomes compared to the control condition. Nevertheless, the results of the cost-effectiveness analysis suggested that the Happiness Route is an acceptable intervention from a health-economic point of view. Our results should be viewed in light of the fact that we could not include the planned number of participants. TRIAL REGISTRATION: Netherlands Trial Register: NTR3377. Registered 2 Apr 2012.

From cosmetics to compassion: A case study of goal focused positive psychotherapy.

This case study describes the progress of a client receiving goal focused positive psychotherapy over 34 sessions, capturing the subtlety and responsiveness of the theory in action. The client self-identified as a Mexican American heterosexual female in her early 20s who had experienced intense anxiety and recurring bouts of depression since elementary school. The primary therapeutic principles of goal focused positive psychotherapy- including hope, strengths, virtuous approach goals, incremental change, and culture- are described alongside germane interventions (one good thing, capitalization, and self-compassion). The client experienced reduction of the initial symptoms (anxiety, pessimism and low self-worth, and deficits in time management and organization). Beyond symptom diminishment, the client achieved increased agency, clarity of virtuous values, genuine caring for others, engagement with a broader range of feelings, and self-compassion. The client's cultural strengths served as a central resource for growth. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Positive psychology intervention for couples: A pilot study.

In this randomized study, a multicomponent, theory-driven, autonomous self-help positive psychology intervention (PPI) for couples was examined. This intervention was not designed for distressed couples but rather to address autonomous couples with a good initial level of functioning who, nonetheless, wished to improve it. The objective was to assess the efficacy of the PPI on satisfaction with life, affective life, communication patterns, and dyadic adjustment in each member of the dyad. The 4-week PPI encompassed dyadic and individual daily activities. Thirty-eight couples were assigned to an intervention group (n = 20 couples) or a waiting list control (WLC) group (n = 18 couples). Assessments were conducted prior to and after the PPI, with an immediate post-test and a follow-up. Ninety-two percent of the PPI was completed by the participants. Linear mixed models revealed improvements in positive emotions, communication patterns of mutuality, and dyadic adjustment from the pretest to the immediate post-test in the intervention group compared with the WLC group. Effects of dyadic adjustment were maintained from pretest to 1-month follow-up in the intervention group. This pilot study suggests that the realization of intentional dyadic activities presents an interesting approach to contribute to individual positive emotions and dyadic functioning.

A positive psychology intervention for patients with bipolar depression: a randomized pilot trial.

Background: There are few effective treatments for bipolar depression, a common and debilitating illness.Aims: We aimed to examine the feasibility and preliminary efficacy of a four-week, telephone-delivered positive psychology (PP) intervention for patients with bipolar depression.Methods: Twenty-five patients hospitalized for bipolar depression were randomized to receive a PP (n = 14) or control condition (CC; n = 11) intervention. Following discharge, participants completed weekly exercises and phone calls with a study trainer. PP intervention feasibility was assessed by the number of exercises completed, and acceptability was examined on five-point Likert-type scales of ease and utility. Between-group differences on psychological constructs at 4 and 8 weeks post-enrollment were assessed using mixed effects regression models.Results: Participants in the PP group completed an average of three out of four PP exercises and found PP exercises to be subjectively helpful, though neither easy nor difficult. Compared to CC, the PP intervention led to trends towards greater improvements in positive affect and optimism at follow-up, with large effect sizes (modified Cohen's d = 0.95-1.24). PP had variable, non-significant effects on negative psychological constructs.Conclusions: Larger, randomized trials are needed to further evaluate the efficacy of this intervention in this high-risk population.

Benefit-Finding Intervention Delivered Individually to Alzheimer Family Caregivers: Longer-Term Outcomes of a Randomized Double-Blind Controlled Trial.

OBJECTIVES: To examine the longer-term effects of benefit-finding on caregivers' depressive symptoms (primary outcome), and global burden, role overload, psychological well-being, and positive aspects of caregiving (secondary outcomes). METHOD: Ninety-six Hong Kong Chinese caregivers of relatives with Alzheimer's disease were randomly assigned to receive the benefit-finding intervention (BFT) or one of the two control conditions, namely, simplified psychoeducation (lectures only; SIM-PE) or standard psychoeducation (STD-PE). Caregivers received four biweekly one-to-one interventions of 3 hours each at their own homes. We focused on outcomes measured at 4- and 10-month follow-ups. The trajectories of intervention effects were modeled by BFT × time and BFT × time2 interaction terms. RESULTS: Mixed-effects regression showed significant BFT × time2 interaction effects on depressive symptoms against both control conditions, suggesting diminishing BFT effects over time. Z tests showed that, compared with controls, BFT participants reported substantial reductions in depressive symptoms at 4-month follow-up (d = -0.85 and -0.75 vs. SIM-PE and STD-PE, respectively). For depressive symptoms measured at 10-month follow-up, BFT was indistinguishable from STD-PE, whereas a moderate effect was observed in comparison with SIM-PE (d = -0.52). Moreover, positive aspects of caregiving, but not other secondary outcomes, continued to show intervention effect up to 10-month follow-up. DISCUSSION: Benefit-finding is an efficacious intervention for depressive symptoms in Alzheimer caregivers, with strong effects in the medium-term post-intervention and possible moderate effects in the longer-term post-intervention.

Self-determination in adolescents and adults with intellectual and developmental disabilities.

PURPOSE OF REVIEW: The importance of self-determination to wellbeing and life satisfaction has been established by research in motivation and education. The present review provides a synthesis of research in these areas at a time when the two lines of research are converging. RECENT FINDINGS: Research has established that youth and adults with intellectual and developmental disabilities (IDD) are not as self-determined as their nondisabled peers and that this negatively impacts the quality of their lives. Further, research has established the positive benefits of a focus on self-determination assessment and intervention for people with IDD. Recent studies illustrate the shifting focus to a life-course development perspective of self-determination and the alignment of assessment and interventions with that perspective. Research on self-determination and IDD outside of the United States has dramatically increased. SUMMARY: Research shows that people with IDD who are more self-determined achieve more positive school and adult outcomes and higher life satisfaction. Assessment of and interventions to promote self-determination have increasingly emphasized all people and are aligning with research in motivation and positive psychology. This provides a foundation for promoting greater community, school, and work inclusion.

Developing a Psychological-Behavioral Intervention in Cardiac Patients Using the Multiphase Optimization Strategy: Lessons Learned From the Field.

BACKGROUND: The Multiphase Optimization Strategy (MOST) is an approach to systematically and efficiently developing a behavioral intervention using a sequence of experiments to prepare and optimize the intervention. PURPOSE: Using a 6 year MOST-based behavioral intervention development project as an example, we outline the results-and resulting decision-making process-related to experiments at each step to display the practical challenges present at each stage. METHODS: To develop a positive psychology (PP) based intervention to promote physical activity after an acute coronary syndrome (N = 255 across four phases), we utilized qualitative, proof-of-concept, factorial design, and randomized pilot experiments, with iterative modification of intervention content and delivery. RESULTS: Through this multiphase approach, we ultimately developed a 12 week, phone-delivered, combined PP-motivational interviewing intervention to promote physical activity. Across stages, we learned several important lessons: (a) participant and interventionist feedback is important, even in later optimization stages; (b) a thoughtful and systematic approach using all information sources is required when conflicting results in experiments make next steps unclear; and (3) new approaches in the field over a multiyear project should be integrated into the development process. CONCLUSIONS: A MOST-based behavioral intervention development program can be efficient and effective in developing optimized new interventions, and it may require complex and nuanced decision-making at each phase.

GET.HAPPY2 - User perspectives on an internet-based self-management positive psychology intervention among persons with and without depression: Results from a retrospective survey.

OBJECTIVE: Previous research suggests that online positive psychology interventions (PPI) are frequently used by individuals with symptoms of depression. We aimed to investigate differences in the way depressed and nondepressed users react to the content of an existing online PPI, originally designed for the general public. METHOD: In a retrospective online survey, we assessed discontinuation parameters, aspects of satisfaction with the program, and negative reactions among users of an online PPI. RESULTS: Bivariate and multivariate analyses showed that, overall, reactions between depressed and nondepressed individuals were similar. Differences were observed concerning reasons for using and for discontinuing the program, the perception of exercises, and negative reactions. CONCLUSIONS: Although satisfaction with the program was high, it did not seem to fully meet users' expectations and might be more difficult to complete during episodes of depression. Implications of this study for the adaptation of online PPIs addressing depressed individuals are discussed.

Is the thought-action repertoire a viable intervention target in substance use populations?

OBJECTIVE: This study examined if general population findings of positive correlations between happiness and breadth of thought-action repertoire (TAR) hold in substance use populations, and tests if the TAR is a modifiable intervention target. METHODS: Using data from a randomized online survey on 468 adults in recovery from problematic substance use, we compared 5 happiness exercises to two control exercises on participants' post-exercise TAR, as measured by Frederickson's Modified Open-Ended Twenty Statements Test (MOETST) and coded specifically for action tendencies. RESULTS: A negative binomial regression model indicated that momentary happiness reported before exercise completion was significantly and positively related to the breadth of action tendency repertoires (exp(b) = 1.05, exp(95% CI) [1.01, 1.09], p = 0.012). Two of five happiness exercises were associated with higher action tendency scores compared to the "Three Hard Things" control condition ("Savoring": exp(b) [95% CI]: 1.51 [1.10, 2.09], X2(df = 1) = 6.36, adj. p = 0.038; "Rose, Thorn, Bud": 1.50 [1.09, 2.06], X2(df = 1) = 6.19, adj. p = 0.038). None were significantly different from a neutral control. Effects were not significant for MOETST raw scores. CONCLUSIONS: Results indicate that momentary happiness is associated with broadened action tendencies among individuals in recovery. Brief, self-administered happiness exercises can successfully broaden this aspect of the thought-action repertoire in this population.
