RESUMEN

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.

RESUMEN

BACKGROUND: Environmental and behavioral interventions hold promise to reduce sugar-sweetened beverage (SSBs) consumption. PURPOSE: To test, among frequent SSB consumers, whether motivations to consume SSBs moderated the effects of (a) a workplace SSB sales ban (environmental intervention) alone, and (b) a "brief motivational intervention" (BI) in addition to the sales ban, on changes in SSB consumption. METHODS: We assessed whether (1) baseline motivations to consume SSBs (craving, psychological stress, or taste enjoyment) impacted changes in daily SSB consumption at 6-month follow-up among frequent (>12oz of SSBs/day) SSB consumers (N = 214); (2) participants randomized to the BI (n = 109) versus to the sales ban only (n = 105) reported greater reductions in SSB consumption at follow-up; and (3) motivations to consume SSBs moderated any changes in SSB consumption. RESULTS: In response to the sales ban alone, individuals with stronger SSB cravings (+1 SD) at baseline showed significantly smaller reductions in daily SSB consumption at 6-month follow-up relative to individuals with weaker (-1 SD) SSB cravings (2.5 oz vs. 22.5 oz), p < .01. Receiving the BI significantly increased reductions for those with stronger SSB cravings: Among individuals with stronger cravings, those who received the BI evidenced significantly greater reductions in daily SSB consumption [M(SE) = -19.2 (2.74) oz] than those who did not [M(SE) = -2.5 (2.3) oz, p < .001], a difference of 16.72 oz. CONCLUSIONS: Frequent SSB consumers with stronger SSB cravings report minimal reductions in daily SSB consumption with a sales ban only, but report greater reductions if they also receive a motivational intervention. Future multilevel interventions for institutions should consider both environmental and individualized multi-level interventions. CLINICAL TRIAL INFORMATION: NCT02585336.

RESUMEN

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.

RESUMEN

Few studies have examined neuroimmune pathways that could contribute to impulsivity in people living with HIV who use substances. Eighty-four methamphetamine-using, sexual minority men with an undetectable HIV viral load were administered the Balloon Analogue Risk Task (BART), a behavioral measure of risk-taking propensity. We examined the associations between kynurenine/tryptophan ratio and phenylalanine/tyrosine ratio with BART scores using multiple linear regression. A higher kynurenine/tryptophan ratio was independently associated with greater BART scores (beta = 0.25; 95% CI = 0.05-1.23; p = 0.034). The phenylalanine/tyrosine ratio was not significantly associated with BART scores. Findings support the need for further research to elucidate the neuroimmune mechanisms linking tryptophan degradation with impulsivity to catalyze the development novel pharmacologic treatments for people living with HIV who use methamphetamine.

RESUMEN

Internalized stigma, shame, and other negative self-conscious emotions are inadequately addressed barriers to HIV-related self-care, particularly among people actively using substances. Innovative approaches are needed to optimize antiretroviral treatment (ART) adherence as well as engagement in HIV care among people living with HIV and substance use disorders. Based on qualitative feedback from providers and patients, we iteratively developed and conducted a proof-of-concept study of a relatively brief transdiagnostic emotion regulation intervention designed to improve ART adherence care by addressing behavioral and psychological barriers, including internalized stigma and shame, among people living with HIV and active substance use disorders. The final intervention included 5 individual sessions focused on metacognitive awareness of emotions and thoughts, cognitive reframing of dysfunctional thoughts about the self using concepts such as self-compassion, and identifying and reaching the participants' personalized HIV-self-care goal(s). All participants received daily texts querying current emotion and weekly texts querying ART adherence and substance use. To extend the effects of the intervention, we developed a personalized bi-directional text component through which participants received their personalized compassionate self-statements, informed by the intervention content, in response to their answers to emotion queries for 8 weeks after the 5 sessions. The texts modeled using compassionate self-statements as a form of cognitive reframing, consistent with cognitive restructuring of distorted core beliefs. We consented 10 participants living with HIV and problematic substance use in the proof-of-concept pilot. Of the 8 participants who completed all intervention sessions, participants replied to 70% of all text messages sent. All 8 reported strong acceptability of the intervention content. This emotion-focused, technology-enhanced intervention demonstrated proof-of-concept, in that this patient population would participate in this intervention. A larger randomized controlled pilot is needed to determine feasibility and acceptability among people living with HIV and substance use disorders, a hard-to-reach and underserved population.

RESUMEN

Theoretically driven smartphone-delivered behavioral interventions that target mechanisms underlying eating behavior are lacking. In this study, we administered a 28-day self-paced smartphone-delivered intervention rooted in an operant conditioning theoretical framework that targets craving-related eating using mindful eating practices. At pre-intervention and 1-month post-intervention, we assessed food cravings among adult overweight or obese women (N = 104; M age = 46.2 ± 14.1 years; M BMI = 31.5 ± 4.5) using ecological momentary assessment via text message (SMS), self-reported eating behavior (e.g., trait food craving), and in-person weight. Seventy-eight participants (75.0%) completed the intervention within 7 months ('all completers'), and of these, 64 completed the intervention within 3 months ('timely completers'). Participants experienced significant reductions in craving-related eating (40.21% reduction; p < .001) and self-reported overeating behavior (trait food craving, p < .001; other measures ps < .01). Reductions in trait food craving were significantly correlated with weight loss for timely completers (r = .30, p = .020), this pattern of results was also evident in all completers (r = .22, p = .065). Taken together, results suggest that smartphone-delivered mindful eating training targeting craving-related eating may (1) target behavior that impacts a relative metabolic pathway, and (2) represent a low-burden and highly disseminable method to reduce problematic overeating among overweight individuals. ClinicalTrials.gov registration: NCT02694731.

RESUMEN

BACKGROUND: Depression is a pervasive psychological issue facing hemodialysis (HD) patients. Novel technology-based treatment strategies that deploy psychology-based interventions have not been the focus for therapy and few published studies exist. The aim of the current trial is to determine the feasibility and acceptability of an Internet-based positive psychological intervention in HD patients with comorbid depressive symptoms. METHODS: HD patients (n = 14) with elevated symptoms of depression were enrolled in a single-arm pre-post trial with clinical assessments at baseline and immediately post intervention. Chairside during regularly scheduled HD treatment, patients utilized a web browser to complete online modules promoting skills for increasing positive emotion over a 5-week period using Apple IPads. Targeted skills included noting of daily positive events, gratitude, positive reappraisal, acts of kindness, and mindfulness/meditation. RESULTS: Twelve of 14 patients completed the program for an 85.7% retention rate. Participants felt satisfied with each session and offered consistently positive feedback. On average, participants visited the website 3.5 times per week. Significant improvements were evident for depressive symptoms (15.3 vs. 10.9; p = 0.04), as per the Center for Epidemiological Studies Depression Scale. CONCLUSIONS: An innovative Internet-based positive psychological intervention represents a feasible and useful therapeutic option for HD patients with depressive symptoms.

RESUMEN

Purpose To determine if high lung shunt fraction (LSF) is an independent prognostic indicator of poor survival in patients who undergo yttrium 90 radioembolization for unresectable liver-dominant metastatic colorectal cancer. Materials and Methods Retrospective data were analyzed from 606 patients (62% men; mean age, 62 years) who underwent radioembolization to treat liver metastases from colorectal adenocarcinoma between July 2002 and December 2011 at 11 U.S. centers. Institutional review board exemptions were granted prior to the collection of data at each site. Overall survival was estimated by using Kaplan-Meier survival and univariate Cox proportional hazards models to examine the effect of LSF on survival and to compare this to other potential prognostic indicators. Multivariate analysis was also performed to determine whether LSF is an independent risk factor for poor survival. Results LSF higher than 10% was predictive of significantly decreased survival (median, 6.9 months vs 10.0 months; hazard ratio, 1.60; P < .001) and demonstrated a mild but significant correlation to serum carcinoembryonic antigen levels and tumor-to-liver volume ratio (Pearson correlation coefficients, 0.105 and 0.113, respectively; P < .05). A progressive decrease in survival was observed as LSF increased from less than 5% to more than 20% (P < .05). LSF did not correlate with the presence of extrahepatic metastases or prior administration of bevacizumab. Conclusion Increased LSF is an independent prognostic indicator of worse survival in patients undergoing radioembolization for liver-dominant metastatic colorectal adenocarcinoma. High LSF correlates poorly to other potential markers of tumor size, such as tumor-to-liver volume ratio or serum carcinoembryonic antigen level, and does not correlate to the presence of extrahepatic metastases. © RSNA, 2016 Online supplemental material is available for this article.

RESUMEN

BACKGROUND: We conducted a randomized pilot trial to examine the feasibility, acceptability, and preliminary efficacy of a 5 week positive affect skills intervention (LILAC: lessons in linking affect and coping) for women with metastatic breast cancer. Additionally, we examined whether online delivery of the intervention would offer comparable benefits as in-person delivery. METHODS: Women with metastatic breast cancer (N = 39) were randomized to an in-person intervention, online intervention, or in-person attention-matched control. Psychological well-being (depression [Center for Epidemiologic Studies Depression Scale], positive and negative affect [Differential Emotions Scale], cancer-specific quality of life [Multidimensional Quality of Life Scale-Cancer Version]), and positive coping (mindfulness, positive-affect skill use, and self-compassion [Self-Compassion Scale: Short-Form]) were assessed at baseline, 1 week post-intervention, and 1 month post-intervention follow-up. RESULTS: The LILAC intervention showed good feasibility, acceptability, and retention. Although the study was not adequately powered to detect between-group differences in change on preliminary efficacy outcomes, within-group comparisons revealed that LILAC participants (in-person and online combined) showed reductions in depression and negative affect by the 1 month follow-up (d = -0.81). Notably, LILAC participants fell below the clinical threshold for depression (Center for Epidemiologic Studies Depression Scale = 16) by the 1 month follow-up (t[17] = -2.22, P = .04, d = -0.52), whereas control participants did not differ from threshold (t[9] = 0.45, P = .66, d = 0.14). CONCLUSIONS: The LILAC intervention, regardless of delivery method, shows feasibility, acceptability, and preliminary efficacy for promoting psychological well-being in women with metastatic breast cancer. This research provides support for a larger randomized trial to test more definitively the potential benefits of LILAC. A strength of the LILAC intervention includes its innovative focus on positive affect. The efficacy of the online delivery suggests the potential for widespread Internet dissemination.

RESUMEN

BACKGROUND: Childbirth fear is linked with lower labor pain tolerance and worse postpartum adjustment. Empirically validated childbirth preparation options are lacking for pregnant women facing this problem. Mindfulness approaches, now widely disseminated, can alleviate symptoms of both chronic and acute pain and improve psychological adjustment, suggesting potential benefit when applied to childbirth education. METHODS: This study, the Prenatal Education About Reducing Labor Stress (PEARLS) study, is a randomized controlled trial (RCT; n = 30) of a short, time-intensive, 2.5-day mindfulness-based childbirth preparation course offered as a weekend workshop, the Mind in Labor (MIL): Working with Pain in Childbirth, based on Mindfulness-Based Childbirth and Parenting (MBCP) education. First-time mothers in the late 3rd trimester of pregnancy were randomized to attend either the MIL course or a standard childbirth preparation course with no mind-body focus. Participants completed self-report assessments pre-intervention, post-intervention, and post-birth, and medical record data were collected. RESULTS: In a demographically diverse sample, this small RCT demonstrated mindfulness-based childbirth education improved women's childbirth-related appraisals and psychological functioning in comparison to standard childbirth education. MIL program participants showed greater childbirth self-efficacy and mindful body awareness (but no changes in dispositional mindfulness), lower post-course depression symptoms that were maintained through postpartum follow-up, and a trend toward a lower rate of opioid analgesia use in labor. They did not, however, retrospectively report lower perceived labor pain or use epidural less frequently than controls. CONCLUSIONS: This study suggests mindfulness training carefully tailored to address fear and pain of childbirth may lead to important maternal mental health benefits, including improvements in childbirth-related appraisals and the prevention of postpartum depression symptoms. There is also some indication that MIL participants may use mindfulness coping in lieu of systemic opioid pain medication. A large-scale RCT that captures real-time pain perceptions during labor and length of labor is warranted to provide a more definitive test of these effects. TRIAL REGISTRATION: The ClinicalTrials.gov identifier for the PEARLS  study is: NCT02327559 . The study was retrospectively registered on June 23, 2014.

RESUMEN

Many individuals with obesity report over eating despite intentions to maintain or lose weight. Two barriers to long-term weight loss are reward-driven eating, which is characterized by a lack of control over eating, a preoccupation with food, and a lack of satiety; and psychological stress. Mindfulness training may address these barriers by promoting awareness of hunger and satiety cues, self-regulatory control, and stress reduction. We examined these two barriers as potential mediators of weight loss in the Supporting Health by Integrating Nutrition and Exercise (SHINE) randomized controlled trial, which compared the effects of a 5.5-month diet and exercise intervention with or without mindfulness training on weight loss among adults with obesity. Intention-to-treat multiple mediation models tested whether post-intervention reward-driven eating and psychological stress mediated the impact of intervention arm on weight loss at 12- and 18-months post-baseline among 194 adults with obesity (BMI: 30-45). Mindfulness (relative to control) participants had significant reductions in reward-driven eating at 6 months (post-intervention), which, in turn, predicted weight loss at 12 months. Post-intervention reward-driven eating mediated 47.1% of the total intervention arm effect on weight loss at 12 months [ß = -0.06, SE(ß) = 0.03, p = .030, 95% CI (-0.12, -0.01)]. This mediated effect was reduced when predicting weight loss at 18 months (p = .396), accounting for 23.0% of the total intervention effect, despite similar weight loss at 12 months. Psychological stress did not mediate the effect of intervention arm on weight loss at 12 or 18 months. In conclusion, reducing reward-driven eating, which can be achieved using a diet and exercise intervention that includes mindfulness training, may promote weight loss (clinicaltrials.gov registration: NCT00960414).

RESUMEN

PURPOSE: To determine the radial head arthroplasty length that best replicates the native radiocapitellar contact pressure. METHODS: Eight cadaveric elbows (4 matched pairs) with an average age of 73 years were tested. All specimens were ligamentously stable and without visible cartilage wear. Radiocapitellar contact pressures were digitally analyzed during simulated joint loading at 0°, 45°, and 90° of elbow flexion and neutral rotation in the intact specimens and after ligament-preserving radial head arthroplasty at -2 mm, 0 mm, and +2 mm of the native length. The results were analyzed using 1-way analysis of variance and post hoc Tukey pairwise comparison tests. RESULTS: Paired analysis demonstrated significantly decreased mean contact pressures when comparing the native versus the minus 2 groups. Significantly decreased maximum contact pressures were also noted between the native and the minus 2 groups. Examining the mean contact pressures showed no significant difference between the native and the zero group and the native and the plus 2 groups. As for the maximum contact pressures, there was also no significant difference between the native and the zero group and the native and the plus 2 group. CONCLUSIONS: Up to 2 mm of overlengthening may be tolerated under simulated loading conditions without significantly increasing contact pressures of the radiocapitellar joint. Surgeons can use this knowledge along with radiographic parameters and intraoperative examination of elbow stability to gauge the appropriate size of the radial head implant to be used in order to decrease the risk of overstuffing the joint and minimizing radiocapitellar chondral wear. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

RESUMEN

The mechanisms underlying the association between positive emotions and physical health remain a mystery. We hypothesize that an upward-spiral dynamic continually reinforces the tie between positive emotions and physical health and that this spiral is mediated by people's perceptions of their positive social connections. We tested this overarching hypothesis in a longitudinal field experiment in which participants were randomly assigned to an intervention group that self-generated positive emotions via loving-kindness meditation or to a waiting-list control group. Participants in the intervention group increased in positive emotions relative to those in the control group, an effect moderated by baseline vagal tone, a proxy index of physical health. Increased positive emotions, in turn, produced increases in vagal tone, an effect mediated by increased perceptions of social connections. This experimental evidence identifies one mechanism-perceptions of social connections-through which positive emotions build physical health, indexed as vagal tone. Results suggest that positive emotions, positive social connections, and physical health influence one another in a self-sustaining upward-spiral dynamic.

RESUMEN

Acute traumatic spinal cord injury (SCI) is recognized as a global problem that can lead to a range of acute and secondary complications impacting morbidity and mortality. There is still a lack of reliable diagnostic and prognostic biomarkers in patients with SCI that could help guide clinical care and identify novel therapeutic targets for future drug discovery. The aim of this prospective controlled study was to determine the cerebral spinal fluid (CSF) and serum profiles of 10 biomarkers as indicators of SCI diagnosis, severity, and prognosis to aid in assessing appropriate treatment modalities. CSF and serum samples of 15 SCI and ten healthy participants were included in the study. The neurological assessments were scored on admission and at discharge from the hospital using the American Spinal Injury Association Impairment Score (AIS) grades. The CSF and serum concentrations of SBDP150, S100B, GFAP, NF-L, UCHL-1, Tau, and IL-6 were significantly higher in SCI patients when compared with the control group. The CSF GBDP 38/44K, UCHL-L1, S100B, GFAP, and Tau levels were significantly higher in the AIS A patients. This study demonstrated a strong correlation between biomarker levels in the diagnosis and injury severity of SCI but no association with short-term outcomes. Future prospective controlled studies need to be done to support the results of this study.

RESUMEN

Extra-articular middle phalangeal neck fractures are uncommon fractures of the hand that are often difficult to treat. Surgery is indicated when closed reduction fails; 1 option is closed reduction and percutaneous pinning. Maintaining closed reduction while inserting K-wires is challenging. We present a new technique for percutaneous pinning of these fractures that was developed to address these issues. Our technique uses flexion of the interphalangeal joints during K-wire insertion to maintain fracture reduction and improve fixation.

RESUMEN

OBJECTIVES: When experiencing negative mood, people often eat to improve their mood. A learned association between mood and eating may cultivate frequent food cravings, detracting from health goals. Training in mindful eating may target this cycle of emotion-craving-eating by teaching individuals to manage urges when experiencing negative mood. We examined the impact of a mobile mindful eating intervention on the link between negative mood and food cravings among overweight women. METHODS: In a single-arm trial, participants (n = 64, M age = 46.1 years, M BMI = 31.5 kg/m2) completed ecological momentary assessments of negative mood and food cravings 3 times/day for 3 days pre- and post-intervention, as well as 1-month post-intervention. Using multilevel linear regression, we compared associations between negative mood and food craving strength at pre- vs. post-intervention (model 1) and post-intervention vs. 1-month follow-up (model 2). RESULTS: In model 1, negative mood interacted with time point (ß = - .20, SE = .09, p = .02, 95% CI [- .38, - .03]) to predict craving strength, indicating that the within-person association between negative mood and craving strength was significantly weaker at post-intervention (ß = 0.18) relative to pre-intervention (ß = 0.38). In model 2, negative mood did not interact with time point to predict craving strength (ß = .13, SE = .09, p = .10, 95% CI - .03, .31]); the association did not significantly differ between post-intervention and 1-month follow-up. CONCLUSIONS: Training in mindful eating weakened the mood-craving association from pre- to post-intervention. The weakened association remained at follow-up. Our findings highlight the mood-craving link as a target-worthy mechanism of mindful eating that should be assessed in clinical trials. TRIAL REGISTRATION: NCT02694731.

RESUMEN

BACKGROUND: Growing evidence links psychological well-being and resilience with superior cardiac health, but there remains a critical scientific gap about whether (or how) interventions that aim to cultivate psychological well-being reduce cardiac risk. Hispanic/Latino people in the United States have high cardiovascular disease risk and poorly controlled blood pressure (BP) compared with their peers of European ancestry, and they represent a population in need of new and innovative therapeutic approaches. As such, a focused intervention to boost psychological well-being holds promise as a novel therapeutic target for hypertension in Hispanic/Latino adults; to date, however, no research has explored whether a causal link is evident. OBJECTIVE: The aim of this paper is to detail the protocol for the ¡Alégrate! (Be Happy!) intervention, a Phase II randomized controlled trial testing initial efficacy in improving BP of a web-based positive psychological intervention designed to boost psychological well-being in Spanish-speaking Hispanic/Latino people with hypertension. METHODS: A total of 70 Hispanic/Latino people aged ≥18 years, fluent in Spanish, and with elevated BP (≥140/90 mm Hg) will be recruited in person from a single Federally Qualified Health Center in Chicago. Enrollees will be randomly assigned to 1 of 2 trial arms: (1) web-based positive psychological intervention or (2) an active control condition (eg, 3 times weekly emotion reporting). Our 5-week Spanish-language ¡Alégrate! intervention is web-based and delivers curricular content via didactic instruction, journaling, and assigned at-home practice-all accessed via our website using investigator-purchased tablet computers, with a unique username and password assigned to each enrollee. Targeted skills include noting daily positive events, positive reappraisal of stressful events, effective expression of gratitude, performing acts of kindness, and regular practice of mindfulness and meditation. The primary outcome is improvement in BP, both sitting values and 24-hour ambulatory readings, as measured at baseline and 5 and 12 weeks from baseline. Secondary outcomes include psychological well-being, engagement in healthy behaviors, and circulating levels of inflammatory markers. The outcomes of interest are collected by trained research staff through in-person interviews using the REDCap software. RESULTS: Activities of the ¡Alégrate! intervention were funded in August 2017, and data collection is ongoing. We expect to submit trial results for peer-reviewed publications in 2021, soon after recruitment has been concluded and statistical analyses are finalized. CONCLUSIONS: Findings will provide evidence on whether interventions to boost psychological well-being and resilience have downstream effects on BP control and cardiovascular health, particularly as they are deployed in the Spanish language with cultural tailoring and via a web-based platform. If effective, we will have an easily disseminatable application that can positively impact well-being profiles and BP control in Hispanic/Latino people, with the possibility of addressing health disparities of this US racial/ethnic minority group.

RESUMEN

BACKGROUND: Adolescent and young adult cancer survivors (AYAs) experience clinically significant distress and have limited access to supportive care services. Interventions to enhance psychological well-being have improved positive affect and reduced depression in clinical and healthy populations but have not been routinely tested in AYAs. OBJECTIVE: The aim of this protocol is to (1) test the feasibility and acceptability of a Web-based positive emotion skills intervention for posttreatment AYAs called Enhancing Management of Psychological Outcomes With Emotion Regulation (EMPOWER) and (2) examine proof of concept for reducing psychological distress and enhancing psychological well-being. METHODS: The intervention development and testing are taking place in 3 phases. In phase 1, we adapted the content of an existing, Web-based positive emotion intervention so that it would be suitable for AYAs. EMPOWER targets 8 skills (noticing positive events, capitalizing, gratitude, mindfulness, positive reappraisal, goal setting, personal strengths, and acts of kindness) and is delivered remotely as a 5-week, Web-based intervention. Phase 2 consisted of a pilot test of EMPOWER in a single-arm trial to evaluate feasibility, acceptability, retention, and adherence and to collect data on psychosocial outcomes for proof of concept. In phase 3, we are refining study procedures and conducting a second pilot test. RESULTS: The project was part of a career development award. Pilot work began in June 2015, and data collection was completed in March 2019. The analysis is ongoing, and results will be submitted for publication by May 2020. CONCLUSIONS: If this intervention proves feasible and acceptable, EMPOWER will be primed for a subsequent large, multisite randomized controlled trial. As a scalable intervention, it will be ideally suited for AYA survivors who would otherwise not have access to supportive care interventions to help manage posttreatment distress and enhance well-being.
