ABSTRACT
Monitoring forest canopies is vital for ecological studies, particularly for assessing epiphytes in rain forest ecosystems. Traditional methods for studying epiphytes, such as climbing trees and building observation structures, are labor, cost intensive and risky. Unmanned Aerial Vehicles (UAVs) have emerged as a valuable tool in this domain, offering botanists a safer and more cost-effective means to collect data. This study leverages AI-assisted techniques to enhance the identification and mapping of epiphytes using UAV imagery. The primary objective of this research is to evaluate the effectiveness of AI-assisted methods compared to traditional approaches in segmenting/identifying epiphytes from UAV images collected in a reserve forest in Costa Rica. Specifically, the study investigates whether Deep Learning (DL) models can accurately identify epiphytes during complex backgrounds, even with a limited dataset of varying image quality. Systematically, this study compares three traditional image segmentation methods Auto Cluster, Watershed, and Level Set with two DL-based segmentation networks: the UNet and the Vision Transformer-based TransUNet. Results obtained from this study indicate that traditional methods struggle with the complexity of vegetation backgrounds and variability in target characteristics. Epiphyte identification results were quantitatively evaluated using the Jaccard score. Among traditional methods, Watershed scored 0.10, Auto Cluster 0.13, and Level Set failed to identify the target. In contrast, AI-assisted models performed better, with UNet scoring 0.60 and TransUNet 0.65. These results highlight the potential of DL approaches to improve the accuracy and efficiency of epiphyte identification and mapping, advancing ecological research and conservation.

BACKGROUND: Recent jail detention is a marker for trait and state suicide risk in community-based populations. However, healthcare providers are typically unaware that their client was in jail and few post-release suicide prevention efforts exist. This protocol paper describes an effectiveness-implementation trial evaluating community suicide prevention practices triggered by advances in informatics that alert CareSource, a large managed care organization (MCO), when a subscriber is released from jail. METHODS: This randomized controlled trial investigates two evidence-based suicide prevention practices triggered by CareSource's jail detention/release notifications, in a partial factorial design. The first phase randomizes ~ 43,000 CareSource subscribers who pass through any Ohio jail to receive Caring Contact letters sent by CareSource or to Usual Care after jail release. The second phase (running simultaneously) involves a subset of ~ 6,000 of the 43,000 subscribers passing through jail who have been seen in one of 12 contracted behavioral health agencies in the 6 months prior to incarceration in a stepped-wedge design. Agencies will receive: (a) notifications of the client's jail detention/release, (b) instructions for re-engaging these clients, and (c) training in suicide risk assessment and the Safety Planning Intervention for use at re-engagement. We will track suicide-related and service linkage outcomes 6 months following jail release using claims data. CONCLUSIONS: This design allows us to rigorously test two intervention main effects and their interaction. It also provides valuable information on the effects of system-level change and the scalability of interventions using big data from a MCO to flag jail release and suicide risk. TRIAL REGISTRATION: The trial is registered at clinicaltrials.gov (NCT05579600). Registered 27 June, 2023.

Human trafficking survivors experience elevated suicide risk in comparison to the general population. Anti-trafficking service providers in the Philippines have identified capacity building in suicide prevention as a critical priority given the insufficient number of trained mental health professionals and lack of culturally adapted evidence-based interventions in the Philippines. We conducted a focused ethnography exploring the experiences of non-mental health professionals working in the anti-human trafficking sector in the Philippines in responding to suicidality among survivors of human trafficking (n = 20). Themes included: emotional burden on service providers, manifestations of stigma regarding suicide, lack of clarity regarding risk assessment, lack of mental health services and support systems, transferring responsibility to other providers, and the need for training, supervision, and organizational systems. We discuss implications for training service providers in the anti-human trafficking sector, as well as cultural adaptation of suicide prevention interventions with human trafficking survivors in the Philippines.

INTRODUCTION: There is growing evidence that computer-delivered or computer-assisted forms of cognitive behavior therapy (CCBT) are helpful, but cost-effectiveness versus standard therapies is not well established. OBJECTIVE: To evaluate the cost-effectiveness of a therapist-supported method for CCBT in comparison to standard cognitive behavior therapy (CBT). METHODS: A total of 154 drug-free major depressive disorder outpatients were randomly assigned to either 16 weeks of standard CBT (up to twenty 50-min sessions) or CCBT using the Good Days Ahead program (including up to 5.5 h of therapist contact). Outcomes were assessed at baseline, weeks 8 and 16, and at 3 and 6 months post-treatment. Economic analyses took into account the costs of services received and work/social role impairment. RESULTS: In the context of almost identical efficacy, a form of CCBT that used only about one third the amount of therapist contact as conventional CBT was highly cost-effective compared to conventional therapy and reduced the adjusted cost of treatment by USD 945 per patient. CONCLUSIONS: A method of CCBT that blended internet-delivered modules and abbreviated therapeutic contact reduced the cost of treatment substantially without adversely affecting outcomes. Results suggest that use of this approach can more than double the access to CBT. Because clinician support in CCBT can be provided by telephone, videoconference, and/or email, this highly efficient form of treatment could be a major advance in remote treatment delivery.

Background: Insomnia has been identified as a key risk factor for suicide, though most studies have been limited to global measures of these constructs. The aim of the present study was to evaluate the link between insomnia symptoms and five different aspects of suicide-related ideation. Participants: 1,160 active U.S. Army service members (719 male; Mage = 31.2; SDage = 8.62). Methods: As part of an archival analysis, retrospectively assessed insomnia, depression, anxiety symptoms, as well as suicide-related ideation, were evaluated. Suicide-related ideation was assessed in terms of: thoughts of death, thoughts of suicide, suicidal plan, suicidal intent, and suicidal communication. Results: Subjects with clinically significant insomnia symptoms were 3.5 times more likely to report any suicide-related ideation, and approximately 3 times more likely to report thoughts of death and thoughts of suicide. More frequent nocturnal awakenings (i.e., waking up three or more times during a single night) were associated with a greater likelihood of reporting thoughts of death or suicide, whereas greater middle insomnia (i.e., waking up and having difficulty getting back to sleep) was associated with lower odds of experiencing thoughts of suicide, suicidal plan, and suicidal intent. Conclusions: A more refined delineation of insomnia and suicide-related ideation may serve to clarify the nature of the association, and potentially offer some clues as to the underlying mechanisms. With regard to potential clinical implications, the results support that careful assessment of insomnia symptoms, suicide-related ideation, and their respective subtypes, is important and may influence how we estimate risk for suicide.

The primary objective of the current study was to examine the perspective of firearm stakeholders, including firearm safety course instructors, members of law enforcement, and firearm retailers, with regard to the implementation of an evidence-based approach to firearm safety promotion, the Firearm Safety Check, as a universal suicide prevention strategy in pediatric primary care. Twelve firearm stakeholders participated in semi-structured interviews. Using an integrated analytic approach, several themes emerged from the interviews. With regard to acceptability of the intervention, participants generally found counseling caregivers to store firearms safely and the provision of firearm locking mechanisms to be acceptable, but expressed concern about screening for firearm ownership in health systems. Participants identified distinct roles of responsibility for firearm advocacy groups, firearm owners, healthcare clinicians, and caregivers with regard to the promotion and execution of safe firearm storage. Participants called for partnerships between healthcare systems and firearm stakeholders, and also identified potential threats to these partnerships, including lack of trust firearm owners may have in health systems and the government. Finally, participants suggested strategies for preventing firearm-related suicides. Findings support a growing body of literature suggesting the value in researchers, health systems, and firearm stakeholders partnering around a shared agenda of firearm safety promotion as a strategy to prevent suicide.

Individuals with multiple suicide attempts have a greater risk for eventual suicide death. We investigated clinical differences in participants with single versus multiple suicide attempts. Individuals with multiple attempts were more likely to have severe depressive symptoms, drug use disorder, and a higher wish to die. Borderline personality disorder traits and drug use disorder were significant predictors of multiple attempts when adjusting for other psychiatric disorders. Participants with multiple attempts sustained higher suicidal ideation-worst and wish to die/wish to live-worst scores during the 3-month assessment period. Clinical differences between individuals with multiple versus single attempts point to the need of tailored suicide prevention efforts.

BACKGROUND: Safety planning is a brief intervention that has become an accepted practice in many clinical settings to help prevent suicide. Even though it is quick compared to other approaches, it frequently requires 20 min or more to complete, which can impede adoption. A self-administered, Web-based safety planning application could potentially reduce clinician time, help promote standardization and quality, and provide enhanced ability to share the created plan. OBJECTIVE: The aim of this study was to design, build, and test the usability of a Web-based, self-administered safety planning application. METHODS: We employed a user-centered software design strategy led by a multidisciplinary team. The application was tested for usability with a target sample of suicidal patients. Detailed observations, structured usability ratings, and Think Aloud procedures were used. Suicidal ideation intensity and perceived ability to cope were assessed pre-post engagement with the Web application. RESULTS: A total of 30 participants were enrolled. Usability ratings were generally strong, and all patients successfully built a safety plan. However, the completeness of the safety plan varied. The mean number of steps completed was 5.5 (SD 0.9) out of 6, with 90% (27/30) of participants completing at least 5 steps and 67% (20/30) completing all 6 steps. Some safety planning steps were viewed as inapplicable to some individuals. Some confusion in instructions led to modifications to improve understandability of each step. Ratings of suicide intensity after completion of the application were significantly lower than preratings, pre: mean 5.11 (SD 2.9) versus post: mean 4.46 (SD 3.0), t27=2.49, P=.02. Ratings of ability to cope with suicidal thoughts after completion of the application were higher than preratings, with the difference approaching statistical significance, pre: mean 5.93 (SD 2.9), post: mean 6.64 (SD 2.4), t27=-2.03, P=.05. CONCLUSIONS: We have taken the first step toward identifying the components needed to maximize usability of a self-administered, Web-based safety planning application. Results support initial consideration of the application as an adjunct to clinical contact. This allows for the clinician or other personnel to provide clarification, when needed, to help the patient build the plan, and to help review and revise the draft.

We implemented an innovative, brief, easy-to-administer 2-part intervention to enhance coping and treatment engagement. The intervention consisted of safety planning and structured telephone follow-up postdischarge with 95 veterans who had 2 or more emergency department (ED) visits within 6 months for suicide-related concerns (i.e., suicide ideation or behavior). The intervention significantly increased behavioral health treatment attendance 3 months after intervention, compared with treatment attendance in the 3 months after a previous ED visit without intervention. The trend was for a decreasing hospitalization rate.

We present an integrative model predicting associations among epiphytism, the tank habit, entangling seeds, C3 vs. CAM photosynthesis, avian pollinators, life in fertile, moist montane habitats, and net rates of species diversification in the monocot family Bromeliaceae. We test these predictions by relating evolutionary shifts in form, physiology, and ecology to time and ancestral distributions, quantifying patterns of correlated and contingent evolution among pairs of traits and analyzing the apparent impact of individual traits on rates of net species diversification and geographic expansion beyond the ancestral Guayana Shield. All predicted patterns of correlated evolution were significant, and the temporal and spatial associations of phenotypic shifts with orogenies generally accorded with predictions. Net rates of species diversification were most closely coupled to life in fertile, moist, geographically extensive cordilleras, with additional significant ties to epiphytism, avian pollination, and the tank habit. The highest rates of net diversification were seen in the bromelioid tank-epiphytic clade (D(crown) = 1.05 My⻹), associated primarily with the Serra do Mar and nearby ranges of coastal Brazil, and in the core tillandsioids (D(crown) = 0.67 My⻹), associated primarily with the Andes and Central America. Six large-scale adaptive radiations and accompanying pulses of speciation account for 86% of total species richness in the family. This study is among the first to test a priori hypotheses about the relationships among phylogeny, phenotypic evolution, geographic spread, and net species diversification, and to argue for causality to flow from functional diversity to spatial expansion to species diversity.

This article discusses joint modeling of compliance and outcome for longitudinal studies when noncompliance is present. We focus on two-arm randomized longitudinal studies in which subjects are randomized at baseline, treatment is applied repeatedly over time, and compliance behaviors and clinical outcomes are measured and recorded repeatedly over time. In the proposed Markov compliance and outcome model, we use the potential outcome framework to define pre-randomization principal strata from the joint distribution of compliance under treatment and control arms, and estimate the effect of treatment within each principal strata. Besides the causal effect of the treatment, our proposed model can estimate the impact of the causal effect of the treatment at a given time on future compliance. Bayesian methods are used to estimate the parameters. The results are illustrated using a study assessing the effect of cognitive behavior therapy on depression. A simulation study is used to assess the repeated sampling properties of the proposed model.

BACKGROUND: The Joint Commission's National Patient Safety Goal (NPSG) for suicide prevention (NPSG.15.01.01) requires that accredited hospitals maintain policies/procedures for follow-up care at discharge for patients identified as at risk for suicide. The proportion of hospitals meeting these requirements through use of recommended discharge practices is unknown. METHODS: This cross-sectional observational study explored the prevalence of suicide prevention activities among Joint Commission-accredited hospitals. A questionnaire was sent to 1,148 accredited hospitals. The authors calculated the percentage of hospitals reporting implementation of four recommended discharge practices for suicide prevention. RESULTS: Of 1,148 hospitals, 346 (30.1%) responded. The majority (nâ¯=â¯212 [61.3%]) of hospitals had implemented formal safety planning, but few of those (nâ¯=â¯41 [19.3%]) included all key components of safety planning. Approximately a third of hospitals provided a warm handoff to outpatient care (nâ¯=â¯128 [37.0%)] or made follow-up contact with patients (nâ¯=â¯105 [30.3%]), and approximately a quarter (nâ¯=â¯97 [28.0%]) developed a plan for lethal means safety. Very few (nâ¯=â¯14 [4.0%]) hospitals met full criteria for implementing recommended suicide prevention activities at time of discharge. CONCLUSION: The study revealed a significant gap in implementation of recommended practices related to prevention of suicide postdischarge. Additional research is needed to identify factors contributing to this implementation gap.

The Safety Planning Intervention (SPI) is an evidence-based therapeutic intervention designed to mitigate suicide risk by providing a suicidal individual with a written, personalized safety plan. The Department of Veterans Affairs (VA) has implemented safety planning, but research found variability in the quality of safety plans. To improve quality, the VA developed an Advanced Training in the Safety Planning Intervention (ASPI) that went beyond previous didactic training efforts by emphasizing experiential learning. The aim of this article is to describe the procedures and initial results of VA's competency-based ASPI Training Program. Before training, providers participating in this program uploaded a written, deidentified safety plan completed with a Veteran. Providers then completed four training components, including evaluation of fidelity of written safety plans and competency in SPI during live, standardized roleplays at the conclusion of training, and at a 3-month follow-up evaluation. Of the 409 providers who initiated training, 367 (90%) completed training, 26 (6%) dropped out of training, and 16 (4%) did not meet the competency requirements for training completion. Relative to pretraining, there was a medium to large increase in the effect size of the quality of written Safety Plans at the end of training that was maintained at the 3-month follow-up. Using a standardized, observational measure of SPI competency, 383 of 391 (98%) providers met competency criteria following the training, and 367 of 375 (98%) providers met competency at 3-month follow-up. Findings suggest that ASPI training is effective in helping providers achieve and maintain fidelity in safety planning. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
ABSTRACT
BACKGROUND: The Safety Planning Intervention with follow-up services (SPI+) is a promising suicide prevention intervention, yet many Emergency Departments (EDs) lack the resources for adequate implementation. Comprehensive strategies addressing structural and organizational barriers are needed to optimize SPI+ implementation and scale-up. This protocol describes a test of one strategy in which ED staff connect at-risk patients to expert clinicians from a Suicide Prevention Consultation Center (SPCC) via telehealth. METHOD: This stepped wedge, cluster-randomized trial compares the effectiveness, implementation, cost, and cost offsets of SPI+ delivered by SPCC clinicians versus ED-based clinicians (enhanced usual care; EUC). Eight EDs will start with EUC and cross over to the SPCC phase. Blocks of two EDs will be randomly assigned to start dates 3 months apart. Approximately 13,320 adults discharged following a suicide-related ED visit will be included; EUC and SPCC samples will comprise patients from before and after SPCC crossover, respectively. Effectiveness data sources are electronic health records, administrative claims, and the National Death Index. Primary effectiveness outcomes are presence of suicidal behavior and number/type of mental healthcare visits and secondary outcomes include number/type of suicide-related acute services 6-months post-discharge. We will use the same data sources to assess cost offsets to gauge SPCC scalability and sustainability. We will examine preliminary implementation outcomes (reach, adoption, fidelity, acceptability, and feasibility) through patient, clinician, and health-system leader interviews and surveys. CONCLUSION: If the SPCC demonstrates clinical effectiveness and health system cost reduction, it may be a scalable model for evidence-based suicide prevention in the ED.

BACKGROUND: Clinical research is required to develop and evaluate suicide prevention interventions in the elderly. However, there is insufficient information available about how to best recruit suicidal older adults for such research. This study evaluated the success and efficiency of five recruitment strategies for a clinical trial on the efficacy of cognitive therapy for suicidal older men. METHODS: For each strategy, the numbers of individuals approached, screened, and enrolled were calculated, and the expenses and time associated with each enrollment estimated. Men who were 60 years or older and who had a desire for suicide over the past month were eligible for the trial. RESULTS: Of 955 individuals considered for trial, 33 were enrolled. Most enrollments were sourced from the Veterans Affairs Behavioral Health Laboratory. Recruiting form this source was also the most time and cost efficient recruitment strategy in the study. CONCLUSIONS: Recruitment strategies are effective when they are based on collaborative relationships between researchers and providers, and utilize an existing infrastructure for involving patients in ongoing research opportunities.

ABSTRACT
BACKGROUND: Clinicians often report that their own anxiety and low self-efficacy inhibit their use of evidence-based suicide prevention practices, including gold-standard screening and brief interventions. Exposure therapy to reduce clinician maladaptive anxiety and bolster self-efficacy use is a compelling but untested approach to improving the implementation of suicide prevention evidence-based practices (EBPs). This project brings together an interdisciplinary team to leverage decades of research on behavior change from exposure theory to design and pilot test an exposure-based implementation strategy (EBIS) to target clinician anxiety to improve suicide prevention EBP implementation. METHODS: We will develop, iteratively refine, and pilot test an EBIS paired with implementation as usual (IAU; didactic training and consultation) in preparation for a larger study of the effect of this strategy on reducing clinician anxiety, improving self-efficacy, and increasing use of the Columbia Suicide Severity Rating Scale and the Safety Planning Intervention in outpatient mental health settings. Aim 1 of this study is to use participatory design methods to develop and refine the EBIS in collaboration with a stakeholder advisory board. Aim 2 is to iteratively refine the EBIS with up to 15 clinicians in a pilot field test using rapid cycle prototyping. Aim 3 is to test the refined EBIS in a pilot implementation trial. Forty community mental health clinicians will be randomized 1:1 to receive either IAU or IAU + EBIS for 12 weeks. Our primary outcomes are EBIS acceptability and feasibility, measured through questionnaires, interviews, and recruitment and retention statistics. Secondary outcomes are the engagement of target implementation mechanisms (clinician anxiety and self-efficacy related to implementation) and preliminary effectiveness of EBIS on implementation outcomes (adoption and fidelity) assessed via mixed methods (questionnaires, chart-stimulated recall, observer-coded role plays, and interviews). DISCUSSION: Outcomes from this study will yield insight into the feasibility and utility of directly targeting clinician anxiety and self-efficacy as mechanistic processes informing the implementation of suicide prevention EBPs. Results will inform a fully powered hybrid effectiveness-implementation trial to test EBIS' effect on implementation and patient outcomes.

ABSTRACT
INTRODUCTION: Brief interventions that reduce suicide risk following youth's experience with acute care due to suicidality are needed. METHODS AND ANALYSIS: The study will use a three-arm randomised controlled trial designed to test the effectiveness of the Safety Planning Intervention with structured follow-up (SPI+) and the Collaborative Assessment and Management of Suicidality (CAMS) compared with enhanced usual care. The primary outcomes measure will be suicidal events, defined as death by suicide, attempted suicide, preparatory acts toward imminent suicidal behaviour or suicidal ideation resulting in a change in emergency evaluation or inpatient admission. Secondary measures will be the number of suicide attempts and severity of suicidal ideation. The experimental interventions, SPI+ and CAMS, consist of up to eight sessions over approximately 8 weeks that are designed to manage (SPI+) or treat (CAMS) patient-identified 'drivers' of suicidal thoughts and behaviours. Mechanisms and moderators of change will be evaluated to understand treatment impacts. ETHICS AND DISSEMINATION: This study has been approved by the Seattle Children's Institutional Review Board and is monitored by external agencies including the University of Washington Institute for Translational Health Sciences, and a National Institute of Mental Health (NIMH)-appointed Data Safety and Monitoring Board. Trial results will help establish evidence towards safe and effective treatment strategies for youth transitioning from acute to outpatient care due to a suicidal crisis. The data will be shared with the NIMH Data Archives and disseminated through publications and conferences. TRIAL REGISTRATION NUMBER: NCT05078970.

Importance: Suicide is a leading cause of deaths in the US. Although the emergency department (ED) is an opportune setting, ED-initiated interventions remain underdeveloped and understudied. Objective: To determine if an ED process improvement package, with a subfocus on improving the implementation of collaborative safety planning, reduces subsequent suicide-related behaviors. Design, Setting, and Participants: The Emergency Department Safety Assessment and Follow-up Evaluation 2 (ED-SAFE 2) trial, a stepped-wedge cluster randomized clinical trial conducted in 8 EDs across the US, used an interrupted time series design with three 12-month sequential phases: baseline, implementation, and maintenance. A random sample of 25 patients per month per site 18 years and older who screened positive on the Patient Safety Screener, a validated suicide risk screener, were included. The primary analyses focused on those who were discharged from the ED, while secondary analyses focused on all patients who screened positive, regardless of disposition. Data were collected on patients who presented for care from January 2014 to April 2018, and data were analyzed from April to December 2022. Interventions: Each site received lean training and built a continuous quality improvement (CQI) team to evaluate the current suicide-related workflow in the ED, identify areas of improvement, and implement efforts to improve. Each site was expected to increase their universal suicide risk screening and implement collaborative safety planning for patients at risk of suicide who were discharged home from the ED. Site teams were centrally coached by engineers experienced in lean CQI and suicide prevention specialists. Main Outcomes and Measures: The primary outcome was a composite comprising death by suicide or suicide-related acute health care visits, measured over a 6-month follow-up window. Results: Across 3 phases, 2761 patient encounters were included in the analyses. Of these, 1391 (50.4%) were male, and the mean (SD) age was 37.4 (14.5) years. A total of 546 patients (19.8%) exhibited the suicide composite during the 6-month follow-up (9 [0.3%] died by suicide and 538 [19.5%] of a suicide-related acute health care visit). A significant difference was observed for the suicide composite outcome between the 3 phases (baseline, 216 of 1030 [21%]; implementation, 213 of 967 [22%]; maintenance, 117 of 764 [15.3%]; P = .001). The adjusted odds ratios of risk of the suicide composite during the maintenance phase was 0.57 (95% CI, 0.43-0.74) compared with baseline and 0.61 (0.46-0.79) compared with the implementation phase, which reflect a 43% and 39% reduction, respectively. Conclusions and Relevance: In this multisite randomized clinical trial, using CQI methods to implement a department-wide change in suicide-related practices, including the implementation of a safety plan intervention, yielded a significant decrease in suicide behaviors in the maintenance period of the study.

BACKGROUND: Suicide attempts and suicide death disproportionately affect sexual and gender minority emerging adults (age 18-24 years). However, suicide prevention strategies tailored for emerging adult sexual and gender minority (EA-SGM) groups are not widely available. The Safety Planning Intervention (SPI) has strong evidence for reducing the risk for suicide in the general population, but it is unclear how best to support EA-SGM groups in their use of a safety plan. Our intervention (Supporting Transitions to Adulthood and Reducing Suicide [STARS]) builds on content from an existing life skills mobile app for adolescent men who have sex with men (iREACH) and seeks to target core risk factors for suicide among EA-SGM groups, namely, positive affect, discrimination, and social disconnection. The mobile app is delivered to participants randomized to STARS alongside 6 peer mentoring sessions to support the use of the safety plan and other life skills from the app to ultimately reduce suicide risk. OBJECTIVE: We will pilot-test the combination of peer mentoring alongside an app-based intervention (STARS) designed to reduce suicidal ideation and behaviors. STARS will include suicide prevention content and will target positive affect, discrimination, and social support. After an in-person SPI with a clinician, STARS users can access content and activities to increase their intention to use SPI and overcome obstacles to its use. EA-SGM groups will be randomized to receive either SPI alone or STARS and will be assessed for 6 months. METHODS: Guided by the RE-AIM (reach, efficacy, adoption, implementation, and maintenance) framework, we will recruit and enroll a racially and ethnically diverse sample of 60 EA-SGM individuals reporting past-month suicidal ideation. Using a type-1 effectiveness-implementation hybrid design, participants will be randomized to receive SPI (control arm) or to receive SPI alongside STARS (intervention arm). We will follow the participants for 6 months, with evaluations at 2, 4, and 6 months. Preliminary effectiveness outcomes (suicidal ideation and behavior) and hypothesized mechanisms of change (positive affect, coping with discrimination, and social support) will serve as our primary outcomes. Secondary outcomes include key implementation indicators, including participants' willingness and adoption of SPI and STARS and staff's experiences with delivering the program. RESULTS: Study activities began in September 2021 and are ongoing. The study was approved by the institutional review board of the University of Pennsylvania (protocol number 849500). Study recruitment began on October 14, 2022. CONCLUSIONS: This project will be among the first tailored, mobile-based interventions for EA-SGM groups at risk for suicide. This project is responsive to the documented gaps for this population: approaches that address chosen family, focus on a life-course perspective, web approaches, and focus on health equity and provision of additional services relevant to sexual and gender minority youth.
