RESUMO
Purpose: We examined the psychometric properties and criterion validity of the Sexual Minority Adolescent Stress Inventory (SMASI) among 730 sexual minority (SM) and transgender and gender-diverse (TGD) youth aged 14 to 24 years who participated in a human immunodeficiency virus study. Methods: We tested the factor structure of the global scale and subscales and measurement invariance across age, gender identity, sex assigned at birth, sexual identity, ethnoracial identity, and city. For criterion validity, we regressed mental health and substance use measures on the global scale. Results: The global scale had excellent fit (comparative fit index = 0.95) and high reliability (omega = 0.89). Subscale model fit was adequate. We confirmed invariance by gender identity and age and established criterion validity. Conclusion: The SMASI exhibits strong psychometric properties among SM emerging adults and TGD youth. Modifications could enhance the SMASI to better capture both sexual and gender minority stress among ethnoracial minority youth.
RESUMO
OBJECTIVES: Treating gender identity as a fixed characteristic may contribute to considerable misclassification and hinder accurate characterization of health inequities and the design of effective preventive interventions for transgender and gender diverse (TGD) adolescents and young adults. We examined changes in how an ethnically and racially diverse sample of TGD adolescents and young adults reported their gender identity over time, the implications of this fluidity on public health, and the potential effects of misclassification of gender identity. METHODS: We recruited 235 TGD adolescents and young adults (aged 15-24 y) in Los Angeles, California, and New Orleans, Louisiana, from May 2017 through August 2019 to participate in an HIV intervention study. We asked participants to self-report their gender identity and sex assigned at birth every 4 months for 24 months. We used a quantitative content analysis framework to catalog changes in responses over time and classified the changes into 3 main patterns: consistent, fluctuating, and moving in 1 direction. We then calculated the distribution of gender identity labels at baseline (initial assessment) and 12 and 24 months and described the overall sample by age, race, ethnicity, and study site. RESULTS: Of 235 TGD participants, 162 (69%) were from Los Angeles, 89 (38%) were Latinx, and 80 (34%) were non-Latinx Black or African American. Changes in self-reported gender identity were common (n = 181; 77%); in fact, 39 (17%) changed gender identities more than twice. More than 50% (n = 131; 56%) showed a fluctuating pattern. CONCLUSIONS: Gender identity labels varied over time, suggesting that misclassification may occur if data from a single time point are used to define gender identity. Our study lays the foundation for launching studies to elucidate the associations between shifting gender identities and health outcomes.

Chatbots increase business productivity by handling customer conversations instead of human agents. Similar rationale applies to use chatbots in the healthcare sector, especially for health coaches who converse with clients. Chatbots are nascent in healthcare. Study findings have been mixed in terms of engagement and their impact on outcomes. Questions remain as to chatbot acceptability with coaches and other providers; studies have focused on clients.To clarify perceived benefits of chatbots in HIV interventions we conducted virtual focus groups with 13 research staff, eight community advisory board members, and seven young adults who were HIV intervention trial participants (clients). Our HIV healthcare context is important. Clients represent a promising age demographic for chatbot uptake. They are a marginalized population warranting consideration to avoid technology that limits healthcare access.Focus group participants expressed the value of chatbots for HIV research staff and clients. Staff discussed how chatbot functions, such as automated appointment scheduling and service referrals, could reduce workloads while clients discussed the after-hours convenience of these functions. Participants also emphasized that chatbots should provide relatable conversation, reliable functionality, and would not be appropriate for all clients. Our findings underscore the need to further examine appropriate chatbot functionality in HIV interventions.

Despite the proven efficacy of pre-exposure prophylaxis (PrEP) in preventing HIV acquisition, PrEP is underutilized by sexual and gender minority young adults in the 13 states in the United States "South." In this paper, we describe the process we used to develop a digital campaign to promote awareness and engagement of sexual and gender minority young adults in the Louisiana Department of Health's TelePrEP Program and provide campaign performance metrics. In Phase 1, we conducted formative research that informed campaign development and strategy. In total, 109 sexual and gender minority young adults completed a survey of PrEP constructs (e.g., facilitators, barriers). We also conducted three, sequential focus groups to iteratively generate, revise and refine the digital material. In collaboration with our strategic marketing partner (SMP), we developed 3 different ads and 1 video ad to promote on web and mobile-in app display, as well as Facebook, Instagram, and YouTube. Phase 2 focused on campaign implementation and evaluation (e.g., number of impressions, user activities on LA TelePrEP landing page). In the first few weeks of the campaign, data from tracking pixels indicated minimal activities on the landing page. We paused to revamp the campaign. Our SMP determined that a more young adult-focused landing page could bolster engagement. We created a new landing page and reran the campaign for 33 days. We saw substantially more user activities on the new landing page (n = 382) compared to the LA TelePrEP landing page (n = 185). Overall, we had 730,665 impressions and 475 link clicks. By collaborating with our SMP, we effectively and efficiently translated our community-engaged formative research into relevant and engaging digital content. This pilot study is one of the first to demonstrate the importance of using tracking pixels to monitor real-time user data to optimize performance of a digital PrEP campaign.

BACKGROUND: Sexual and gender minority (SGM) adolescents and young adults (AYAs) are at increased risk of HIV infection, particularly in the Southern United States. Despite the availability of effective biomedical prevention strategies, such as pre-exposure prophylaxis (PrEP), access and uptake remain low among SGM AYAs. In response, the Louisiana Department of Health initiated the LA TelePrEP Program, which leverages the power of telemedicine to connect Louisiana residents to PrEP. A virtual TelePrEP Navigator guides users through the enrollment process, answers questions, schedules appointments, and facilitates lab testing and medication delivery. To increase the participation of SGM AYAs in the program, the TelePrEP program partnered with researchers to develop a chatbot that would facilitate access to the program and support navigator functions. Chatbots are capable of carrying out many functions that reduce employee workload, and despite their successful use in health care and public health, they are relatively new to HIV prevention. OBJECTIVE: In this paper, we describe the iterative and community-engaged process that we used to develop an SMS text messaging-based chatbot tailored to SGM AYAs that would support navigator functions and disseminate PrEP-related information. METHODS: Our process was comprised of 2 phases: conceptualization and development. In the conceptualization phase, aspects of navigator responsibilities, program logistics, and user interactions to prioritize in chatbot programming (eg, scheduling appointments and answering questions) were identified. We also selected a commercially available chatbot platform that could execute these functions and could be programmed with minimal coding experience. In the development phase, we engaged Department of Health staff and SGM AYAs within our professional and personal networks. Five different rounds of testing were conducted with various groups to evaluate each iteration of the chatbot. After each iteration of the testing process, the research team met to discuss feedback, guide the programmer on incorporating modifications, and re-evaluate the chatbot's functionality. RESULTS: Through our highly collaborative and community-engaged process, a rule-based chatbot with artificial intelligence components was successfully created. We gained important knowledge that could advance future chatbot development efforts for HIV prevention. Key to the PrEPBot's success was resolving issues that hampered the user experience, like asking unnecessary questions, responding too quickly, and misunderstanding user input. CONCLUSIONS: HIV prevention researchers can feasibly and efficiently program a rule-based chatbot with the assistance of commercially available tools. Our iterative process of engaging researchers, program personnel, and different subgroups of SGM AYAs to obtain input was key to successful chatbot development. If the results of this pilot trial show that the chatbot is feasible and acceptable to SGM AYAs, future HIV researchers and practitioners could consider incorporating chatbots as part of their programs.

RESUMO
Despite recent emphasis on couples-based HIV prevention interventions, efficacious interventions for Latino male couples have yet to be tested. The study examined the feasibility and acceptability of the Connecting Latinos en Pareja (CLP) intervention, a couples-based HIV prevention intervention for Latino male couples. This pilot demonstrated high feasibility, meeting targets for recruitment, retention, and intervention completion. We recruited a diverse cohort of 46 individuals/23 couples with a retention rate of 80% over 6 months and a 100% intervention completion rate in both conditions (four structured couple sessions in each condition). This pilot RCT was not powered to detect significant intervention impact on the primary outcome; however, there was a significant increase in relationship functioning among couples in the intervention group relative to controls and promising trends in changes in several key outcome and mediating variables. Secondary analysis documented trends in the expected directions for several other key hypothesized mechanisms of action (stimulant use, psychological symptoms, quality of life) as well as the primary outcome of proportion of protected sex acts (overall and broken out by main vs. outside partners). Qualitative exit interviews revealed high levels of acceptability of the CLP intervention. Participants highlighted affective component of the intervention and perceived effectiveness in improving dyadic communication skills and safer sex practices. Our findings show that a pilot trial of CLP is highly feasible and acceptable, with CLP demonstrating promising evidence of changes in key intervention mechanisms.

Background: Understanding the barriers and facilitators of implementation completion is critical to determining why some implementation efforts fail and some succeed. Such studies provide the foundation for developing further strategies to support implementation completion when scaling up evidence-based practices (EBPs) such as Motivational Interviewing. Method: This mixed-methods study utilized the Exploration, Preparation, Implementation, and Sustainment framework in an iterative analytic design to compare adolescent HIV clinics that demonstrated either high or low implementation completion in the context of a hybrid Type III trial of tailored motivational interviewing. Ten clinics were assigned to one of three completion categories (high, medium, and low) based on percentage of staff who adhered to three components of implementation strategies. Comparative analysis of staff qualitative interviews compared and contrasted the three high-completion clinics with the three low-completion clinics. Results: Results suggested several factors that distinguished high-completion clinics compared to low-completion clinics including optimism, problem-solving barriers, leadership, and staff stress and turnover. Conclusions: Implementation strategies targeting these factors can be added to EBP implementation packages to improve implementation success. Plain Language Summary: While studies have begun to address adherence to intervention techniques, this is one of the first studies to address organizational adherence to implementation strategies. Youth HIV providers from different disciplines completed interviews about critical factors in both the inner and outer context that can support or hinder an organization's adherence to implementation strategies. Compared to less adherent clinics, more adherent clinics reported more optimism, problem-solving, and leadership strengths and less staff stress and turnover. Implementation strategies addressing these factors could be added to implementation packages to improve implementation success.
RESUMO
OBJECTIVES: To evaluate the association between provider adherence to Tailored Motivational Interviewing implementation strategy and motivational interviewing (MI) competence. METHODS: 156 youth-focused HIV providers enrolled in a parent implementation science trial completed: a) quarterly standardized patient assessments (SPI) during Baseline; b) a workshop, individual coaching sessions, and quarterly SPI plus feedback during Implementation; and c) quarterly SPI during Sustainment. Competence was measured using the MI-CRS and tracking data was used to assess adherence. We examined overall adherence as well as adherence to each implementation strategy in relation to MI competence. RESULTS: Overall adherence was not associated with overall MI competence. MI competence significantly increased from Baseline to Implementation and Baseline to Sustainment. Some individual implementation strategies were associated with change in competence and the probability of achieving Intermediate/Advanced competence. CONCLUSIONS: The results suggest that 100% percent adherence to all TMI implementation strategies may not be necessary. Completing some of the TMI implementation strategies yielded improvements in MI competence. The use of routine tracking data to measure adherence maybe more pragmatic than using observational coders and more objective than self-reports. PRACTICE IMPLICATIONS: In busy HIV clinics, MI training should focus on strategies most directly associated with increased provider competence.

Psychological researchers often use standard linear regression to identify relevant predictors of an outcome of interest, but challenges emerge with incomplete data and growing numbers of candidate predictors. Regularization methods like the LASSO can reduce the risk of overfitting, increase model interpretability, and improve prediction in future samples; however, handling missing data when using regularization-based variable selection methods is complicated. Using listwise deletion or an ad hoc imputation strategy to deal with missing data when using regularization methods can lead to loss of precision, substantial bias, and a reduction in predictive ability. In this tutorial, we describe three approaches for fitting a LASSO when using multiple imputation to handle missing data and illustrate how to implement these approaches in practice with an applied example. We discuss implications of each approach and describe additional research that would help solidify recommendations for best practices. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Health-science researchers often measure psychological constructs using multi-item scales and encounter missing items on some participants. Multiple imputation (MI) has emerged as an alternative to ad-hoc methods (e.g., mean substitution) for handling incomplete data on multi-item scales, appealingly reflecting available information while accounting for uncertainty due to missing values in a unified inferential framework. However, MI can be implemented in a variety of ways. When the number of variables to impute gets large, some strategies yield unstable estimates of quantities of interest while others are not technically feasible to implement. These considerations raise pragmatic questions about the extent to which ad-hoc procedures would yield statistical properties that are competitive with theoretically motivated methods. Drawing on an HIV study where depression and anxiety symptoms are measured with multi-item scales, this empirical investigation contrasts ad-hoc methods for handling missing items with various MI implementations that differ as to whether imputation is at the item-level or scale-level and how auxiliary variables are incorporated. While the findings are consistent with previous reports favoring item-level imputation when feasible to implement, we found only subtle differences in statistical properties across procedures, suggesting that weaknesses of ad-hoc procedures may be muted when missing data percentages are modest.
RESUMO
We report a macrocyclic ligand (H3L6) based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing three acetate pendant arms and a benzyl group attached to the fourth nitrogen atom of the macrocycle. The X-ray structures of the YL6 and TbL6 complexes reveal nine coordination of the ligand to the metal ions through the six nitrogen atoms of the macrocycle and three oxygen atoms of the carboxylate pendants. A combination of NMR spectroscopic studies (1H, 13C, and 89Y) and DFT calculations indicated that the structure of the YL6 complex in the solid state is maintained in an aqueous solution. The detailed study of the emission spectra of the EuL6 and TbL6 complexes revealed Ln3+-centered emission with quantum yields of 7.0 and 60%, respectively. Emission lifetime measurements indicate that the ligand offers good protection of the metal ions from surrounding water molecules, preventing the coordination of water molecules. The YL6 complex is remarkably inert with respect to complex dissociation, with a lifetime of 1.7 h in 1 M HCl. On the other hand, complex formation is fast (â¼1 min at pH 5.4, 2 × 10-5 M). Studies using the 90Y-nuclide confirmed fast radiolabeling since [90Y]YL6 is nearly quantitatively formed (radiochemical yield (RCY) > 95) in a short time over a broad range of pH values from ca. 2.4 to 9.0. Challenging experiments in the presence of excess ethylenediaminetetraacetic acid (EDTA) and in human serum revealed good stability of the [90Y]YL6 complex. All of these experiments combined suggest the potential application of H3L6 derivatives as Y-based radiopharmaceuticals.

The substance use, violence, and AIDS (SAVA) syndemic framework is used to study risk for HIV/AIDS. As a secondary analysis from a large HIV/AIDS prevention study, we categorized participants into having from zero to three SAVA conditions based on the presence or absence of self-reported substance use in the past 4 months, history of lifetime sexual abuse, and intimate partner violence. We used Poisson regression models to examine the association between the number of SAVA conditions and sexual risk behavior. Among all participants (n = 195, median age, 20), 37.9%, 19.5%, and 6.7% reported occurrence of one, two, and all three SAVA conditions, respectively. We found that more than one SAVA condition experienced by women was significantly associated with having more than one sex partner (adjusted prevalence ratio [aPR] = 1.88; 95% confidence interval [CI] = 1.28, 2.76) and with substance use before sex (aPR = 1.61 95% CI = 1.06, 2.45).

HIV researchers use short messaging service (SMS)-based surveys to monitor health behaviors more closely than what would be possible with in-person assessment. Benefits are tempered by nonresponse to completing surveys. Understanding response patterns and their associated study participant characteristics would guide more tailored use of SMS-based surveys for HIV studies. We examined response to weekly 7-item SMS surveys administered as part of an HIV prevention trial. Using Mixture hidden Markov models (MHMM), we identified the underlying response patterns shared by subgroups of participants over time and quantified the association between these response patterns and participant characteristics. Three underlying response patterns were identified; responders, responders with phone-related errors, and non-responders. Non-responders versus responders were more likely to be younger, male, cis-gender, Black and Latinx participants with histories of homelessness, incarceration, and social support service utilization. Responders with phone-related errors compared to non-responders were more likely to be Black, Latinx, female, students, and have a history of incarceration and social support service utilization. More nuanced results from MHMM analyses better inform what strategies to use for increasing SMS response rates, including assisting in securing phone ownership/service for responders with phone-related errors and identifying alternative strategies for non-responders. Actively collecting and monitoring non-delivery notification data available from SMS gateway service companies offers another opportunity to identify and connect with participants when they are willing but unable to respond during follow-up.

Myeloperoxidase (MPO) is a myeloid-lineage restricted enzyme largely expressed in the azurophilic granules of neutrophils. It catalyses the formation of reactive oxygen species, mainly hypochlorous acid, contributing to anti-pathogenic defense. Disorders in the production or regulation of MPO may lead to a variety of health conditions, mainly of inflammatory origin, including autoimmune inflammation. We have studied the effect of ionizing radiation on the activity of MPO, as measured by the capacity retained by the enzyme to produce hypochlorous acid as reactive oxygen species after exposure to successive doses of solvated electrons, the strongest possible one-e- reducing agent in water. Chlorination activity was still present after a very high irradiation dose, indicating that radiation damage does not take place at the active site, hindered in the core of MPO structure. Decay kinetics show a dependence on the wavelength, supporting that the process must occur at peripheral functional groups situated on external and readily accessible locations of the enzyme. These results are relevant to understand the mechanism of resistance of our innate anti-pathogenic defense system and also to get insight into potential strategies to regulate MPO levels as a therapeutic target in autoimmune diseases.

BACKGROUND: Of new sexually transmitted infections (STIs) in the United States, 50% occur among youth aged 15 to 24 years. Previous studies among youth with HIV (YHIV) do not distinguish STI trends among individuals with perinatally (YPHIV) and nonperinatally (YNPHIV) acquired HIV. METHODS: Among 3 Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) studies conducted between 2009 and 2015, we estimated incident diagnoses of trichomonal, bacterial, viral, and overall STIs stratified by sex assigned at birth, mode of HIV acquisition (perinatal [YPHIV] and nonperinatal [YNPHIV]), age (13-17 and 18-24 years), CD4 count (<200, 200-499, and ≥500/µL), and HIV viral load (VL) (<400 and ≥400 copies/mL). RESULTS: Among 3131 YHIV, across the 3 studies, mean (SD) age was 20.6 (2.6) years, 888 (28%) were female, 2498 (80%) had nonperinatal HIV acquisition recorded, and 2298 (73%) were African American/Black. Mean follow-up was 0.9 (0.3) years. Compared with YPHIV, YNPHIV spent less person-time with VL <400 copies/mL (47% vs. 53%) and more time off antiretroviral therapy (49% vs. 15%), and had higher overall STI rates (males, 65.9 vs. 8.5/100 person-years [PY]; females, 54.7 vs. 17.2/100 PY). Among YPHIV, bacterial STIs were higher during person-time spent with VL ≥400 vs. <400 copies/mL (male YPHIV, 10.9 vs. 0.6/100 PY; female YPHIV, 11.2 vs. 2.9/100 PY); no difference was observed among YNPHIV, which may be due to concurrent acquisition of HIV and other STIs and limited follow-up. CONCLUSIONS: Compared with YPHIV, YNPHIV spent less time on antiretroviral therapy and virologically suppressed; YNPHIV also had higher STI diagnosis rates. Very high STI diagnosis rates among YHIV, including among those without virologic suppression, highlight the importance of youth-focused efforts to support durable virologic suppression and identify and treat STIs.

There is a dearth of research on the intersection of incarceration and psychological distress among men who have sex with men including African American (AAMSM) and Latino MSM (LMSM), populations which bear a large burden of HIV in the U.S. Recent incarceration is an important context to examine psychological distress given the critical implications it has on health outcomes. Using baseline data from the Latino and African American Men's Project (LAAMP), a multi-site randomized HIV behavioral intervention trial, this paper examined the association between previous incarceration within the past three months (i.e., recent incarceration) and psychological distress in the past four weeks, assessed by the Kessler Psychological Distress Scale (K10). Among 1482 AAMSM and LMSM (AAMSM: 911, LMSM: 571), we found 768 (52%) were previously incarcerated, but not in past three months and 138 (9.3%) had been recently incarcerated. After adjusting for race, education, access to resources, current living arrangement, HIV status, and substance use, participants who had been recently incarcerated were more likely to have mild psychological distress i.e., K10 score 20-24 (aRRR:1.43, 95% CI 1.20, 1.71) or severe psychological distress, i.e., K10 score > 30 (aRRR: 1.89, 95% CI 1.22, 2.93) in the past four weeks than those never incarcerated and those previously incarcerated, but not in past three months. Our findings have implications for mental health and HIV prevention services for AAMSM and LMSM with previous incarceration within the past three months.

Youth at-risk for HIV are also at-risk for mental health disorders and psychiatric hospitalization. Understanding the association between engagement in HIV prevention, concurrent risk behaviors, and psychiatric hospitalization may lead to improvements in integrated prevention and mental health treatment efforts. Youth at-risk for HIV, aged 14-24 years old, predominantly Black/African American and Latinx (75%) were recruited through youth-serving clinics and community sites in Los Angeles (n = 839) and New Orleans (n = 647). We compared youth with and without histories of psychiatric hospitalization on engagement in HIV prevention, concurrent risk behaviors, and demographic characteristics. We examined predictors of hospitalization using multiple imputations for missing data. Hospitalized youth (30%) were more involved in HIV programs, but were less likely to use PrEP/PEP or condoms than non-hospitalized youth. The odds of hospitalization were higher for transgender/gender nonconforming youth relative to cisgender youth; the OR was increased after adjustment for concurrent risk behaviors. Hospitalization was associated with homelessness, trauma, incarceration, substance use, and involvement in substance abuse treatment programs. There is a continuing need to integrate the diagnosis and treatment of mental health disorders into HIV prevention programs to better address multiple challenges faced by vulnerable youth.

BACKGROUND: The COVID-19 pandemic illuminated the benefits of telemedicine. Self-collected specimens are a promising alternative to clinician-collected specimens when in-person testing is not feasible. In this study, we assessed the adequacy of self-collected pharyngeal and rectal specimens for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae among individuals undergoing chlamydia and gonorrhea screening. METHODS: We used data from a large cohort study that included male and female adolescents between the ages of 12-24 years. We considered self-collected specimens adequate for clinical use if the human synthase gene (a control target of the assay) was detected in the specimen. RESULTS: In total, 2,458 specimens were included in the analysis. The human synthase gene was detected in 99.2% (2,439/2,458) of all self-collected specimens, 99.5% (1,108/1,114) of the pharyngeal specimens, and 99.0% (1,331/1,344) of the rectal specimens. CONCLUSION: Self-collected pharyngeal and rectal specimens demonstrated a very high proportion of human gene presence, suggesting that self-collection was accurate. A limitation of this study is that the sample adequacy control detects the presence or absence of the human hydroxymethylbilane synthase gene, but it does not indicate the specific anatomic origin of the human hydroxymethylbilane synthase gene. Self-collected specimens may be an appropriate alternative to clinician-collected specimens.

In response to the COVID-19 pandemic, our team adjusted study procedures to support research staff wellbeing. ATN CARES is a community-based, adolescent-focused HIV research program. Our participants and frontline staff alike are predominantly Black or Latinx sexual and gender minorities. Senior researchers and staff collaborated to refine our procedures, anticipating stay-at-home orders in March 2020. Transition to virtual space appeared seamless; however, we did not foresee that staff would have the additional role of providing COVID-19-related informational and emotional support to participants. This and the added strain of working remotely were increasing staff stress and in general negatively affecting staff wellbeing. Leveraging staff interests and skills, staff and senior researchers developed purposeful ways to stay connected and alleviate these strains, including exercise sessions; professional development workshops; motivational messages; and games. These proved beneficial and serve as a reminder that wellbeing of staff-our frontline heroes-is vital to a successful research project.

Machine learning creates new opportunities to design digital health interventions for youth at risk for acquiring HIV (YARH), capitalizing on YARH's health information seeking on the internet. To date, researchers have focused on descriptive analyses that associate individual factors with health-seeking behaviors, without estimating of the strength of these predictive models. We developed predictive models by applying machine learning methods (i.e., elastic net and lasso regression models) to YARH's self-reports of internet use. The YARH were aged 14-24 years old (N = 1287) from Los Angeles and New Orleans. Models were fit to three binary indicators of YARH's lifetime internet searches for general health, sexual and reproductive health (SRH), and social service information. YARH responses regarding internet health information seeking were fed into machine learning models with potential predictor variables based on findings from previous research, including sociodemographic characteristics, sexual and gender minority identity, healthcare access and engagement, sexual behavior, substance use, and mental health. About half of the YARH reported seeking general health and SRH information and 26% sought social service information. Areas under the ROC curve (≥ .75) indicated strong predictive models and results were consistent with the existing literature. For example, higher education and sexual minority identification was associated with seeking general health, SRH, and social service information. New findings also emerged. Cisgender identity versus transgender and non-binary identities was associated with lower odds of general health, SRH, and social service information seeking. Experiencing intimate partner violence was associated with higher odds of seeking general health, SRH, and social service information. Findings demonstrate the ability to develop predictive models to inform targeted health information dissemination strategies but underscore the need to better understand health disparities that can be operationalized as predictors in machine learning algorithms.
