Although common, sibling aggression among youth is not well studied. This is a major omission in the literature, as sibling relationships have been found to influence other relationships. As such, the current study evaluates the links between self-reported sibling proactive and reactive aggression and peer proactive and reactive aggression six months later in a sample of 290 (54.8% male) elementary school-age youth who reported having at least one sibling. Gender differences in associations were also examined. Findings indicated that sibling reactive aggression was positively associated with peer reactive aggression six months later, over and above the stability of sibling proactive aggression and peer reactive aggression. Similarly, sibling proactive aggression was associated with peer proactive aggression over and above the stability of sibling reactive aggression and peer proactive aggression. However, gender differences were evident for proactive aggression. That is, sibling proactive aggression was associated with subsequent peer proactive aggression for boys only. Findings indicated that both sibling proactive and reactive aggression are associated with subsequent peer aggression within an academic year, suggesting the need to better understand sibling aggression for the prevention of aggression across relationships. Further, it appears that sibling proactive aggression is more influential on proactively aggressive behaviors toward peers for boys than girls.

Background: In the United States, racial and ethnic disparities in substance use treatment outcomes are persistent, especially among underrepresented minority (URM) populations. Technology-based interventions (TBIs) for substance use treatment show promise in reducing barriers to evidence-based treatment, yet no studies have described how TBIs may impact racial or ethnic health equity. Objective: This study explored whether TBIs in substance use treatment research promote health equity among people who identify as African American or Black, Hispanic or Latino, and American Indian or Alaska Native through their inclusion in research. We explored whether research that includes the aforementioned groups consciously considers race and/or ethnicity beyond including these populations as participants. Methods: We conducted a scoping review of 5 electronic databases to identify TBIs in substance use treatment studies published in English between January 2000 and March 2021. Studies were included if ≥50% of participants identified as African American or Black, Hispanic or Latino, or American Indian or Alaska Native when combined. Included studies were evaluated for conscious consideration of race and ethnicity in at least one manuscript section. Finally, we conducted a critical appraisal of each study’s potential to facilitate insights into the impact of a TBI for members of specific URM groups. Results: Of 6897 titles and abstracts screened and 1158 full-text articles assessed for eligibility, nearly half (532/1158, 45.9%) of the full-text articles were excluded due to the absence of data on race, ethnicity, or not meeting the aforementioned demographic eligibility criteria. Overall, 110 studies met the inclusion criteria. Study designs included 39.1% (43/110) randomized trials, and 35.5% (39/110) feasibility studies. In total, 47.3% (52/110) of studies used computer-based interventions, including electronic screening, brief interventions, and referrals to treatment, whereas 33.6% (37/110) used interactive voice response, ecological momentary assessment or interventions, or SMS text messaging via mobile phones. Studies focused on the following substances: alcohol or drugs (45/110, 40.9%), alcohol alone (26/110, 23.6%), opioids (8/110, 7.3%), cannabis (6/110, 5.5%), cocaine (4/110, 3.6%), and methamphetamines (3/110, 2.7%). Of the studies that consciously considered race or ethnicity (29/110, 26.4%), 6.4% (7/110) explicitly considered race or ethnicity in all manuscript sections. Overall, 28.2% (31/110) of the studies were critically appraised as having a high confidence in the interpretability of the findings for specific URM groups. Conclusions: While the prevalence of TBIs in substance use treatment has increased recently, studies that include and consciously consider URM groups are rare, especially for American Indian or Alaska Native and Hispanic or Latino groups. This review highlights the limited research on TBIs in substance use treatment that promotes racial and ethnic health equity and provides context, insights, and direction for researchers working to develop and evaluate digital technology substance use interventions while promoting health equity.

Background: Although tobacco use has significantly declined in the general population, traditional tobacco use treatment uptake and success rates remain disproportionately low among people who identify as African American/Black, Hispanic/Latina/o, and American Indian/Alaska Native. Technology-based interventions (TBIs) for tobacco use are promising alternatives to traditional tobacco use treatments. Objective: This scoping review aims to investigate the extent to which the use of digital TBIs in tobacco use treatment research promotes health equity among people who identify as African American/Black, Hispanic/Latina/o, and American Indian/Alaska Native. Methods: This scoping review identifies US-based studies (between January 2000 and March 2021) that enlist TBIs for tobacco use treatment and include people who identify as African American/Black, Hispanic/Latina/o, and American Indian/Alaska Native at ≥50% of the sample when combined; features studies that are also race and ethnicity conscious; and highlights health equity–promoting insights from included studies. Results: In 85% (22/26) of the studies, the largest proportion of the sample was African American/Black, most participants had low socioeconomic status, and recruitment was most commonly from medical settings. In total, 58% (15/26) of the studies were race and ethnicity conscious, and 67% (10/15) of these studies sought to partner with potential end users. An array of TBIs were represented; however, SMS text messaging was most prevalent. Most TBIs were combined with other evidence-based intervention components (eg, nicotine replacement therapy). Approximately one-third of the studies (8/26, 31%) required participants to have their own device or internet access. The majority were underpowered to detect substantial differences. Conclusions: The modest number of studies, particularly for persons who identify as Hispanic/Latina/o and American Indian/Alaska Native, demonstrates the limited application of TBIs for tobacco use and that additional research is needed to determine the extent to which TBIs for tobacco use promote health equity among these populations.

Youth substance use continues to be a public health concern, with both aggressive behavior and symptoms of depression commonly identified as risk factors for adolescent substance use. However, more research is needed to understand how proactive and reactive functions of aggression are uniquely associated with the frequency of use of specific substances and how these functions of aggression interact with symptoms of depression to contribute to substance use. To this end, the current study examined these associations in a sample of detained youth (N = 229; 80.7% Male). Results suggested that reactive aggression is uniquely associated with traditional cigarette, alcohol, and marijuana use, while proactive aggression is uniquely associated with prescription drug use. Further, although symptoms of depression did not uniquely contribute to the frequency of substance use, symptoms of depression moderate links between proactive aggression and frequency of traditional cigarette, alcohol, and prescription drug use such that proactive aggression is associated with increased frequency of use only when symptoms of depression are low. Findings suggest the need to consider functions of aggression when identifying risk for frequent substance use, as there may be distinct targets of intervention depending on the function of aggression.

Background: Social media sites, dating apps, and information search sites have been used to reach individuals at high risk for HIV infection. However, it is not clear which platform is the most efficient in promoting home HIV self-testing, given that the users of various platforms may have different characteristics that impact their readiness for HIV testing. Objective: This study aimed to compare the relative effectiveness of social media sites, dating apps, and information search sites in promoting HIV self-testing among minority men who have sex with men (MSM) at an increased risk of HIV infection. Test kit order rates were used as a proxy to evaluate promotion effectiveness. In addition, we assessed differences in characteristics between participants who ordered and did not order an HIV test kit. Methods: Culturally appropriate advertisements were placed on popular sites of three different platforms: social media sites (Facebook, Instagram), dating apps (Grindr, Jack’D), and information search sites (Google, Bing). Advertisements targeted young (18-30 years old) and minority (Black or Latinx) MSM at risk of HIV exposure. Recruitment occurred in 2 waves, with each wave running advertisements on 1 platform of each type over the same period. Participants completed a baseline survey assessing sexual or injection use behavior, substance use including alcohol, psychological readiness to test, attitudes toward HIV testing and treatment, and HIV-related stigma. Participants received an electronic code to order a free home-based HIV self-test kit. Follow-up assessments were conducted to assess HIV self-test kit use and uptake of pre-exposure prophylaxis (PrEP) at 14 and 60 days post enrollment. Results: In total, 271 participants were enrolled, and 254 were included in the final analysis. Among these 254 participants, 177 (69.7%) ordered a home HIV self-test kit. Most of the self-test kits were ordered by participants enrolled from dating apps. Due to waves with low enrollment, between wave statistical comparisons were not feasible. Within wave comparison revealed that Jack’D showed higher order rates (3.29 kits/day) compared to Instagram (0.34 kits/day) and Bing (0 kits/day). There were no associations among self-test kit ordering and HIV-related stigma, perceptions about HIV testing and treatment, and mistrust of medical organizations. Conclusions: Our findings show that using popular dating apps might be an efficient way to promote HIV self-testing. Stigma, perceptions about HIV testing and treatment, or mistrust of medical organizations may not affect order rates of HIV test kits promoted on the internet.

Background: Technology-based interventions (TBIs; ie, web-based and mobile interventions) have the potential to promote health equity in substance use treatment (SUTx) for underrepresented groups (people who identify as African American/Black, Hispanic/Latinx, and American Indian/Alaskan Native) by removing barriers and increasing access to culturally relevant effective treatments. However, technologies (emergent and more long-standing) may have unintended consequences that could perpetuate health care disparities among people who identify as a member of one of the underrepresented groups. Health care research, and SUTx research specifically, is infrequently conducted with people who identify with these groups as the main focus. Therefore, an improved understanding of the literature at the intersection of SUTx, TBIs, and underrepresented groups is warranted to avoid exacerbating inequities and to promote health equity. Objective: This study aims to explore peer-reviewed literature (January 2000-March 2021) that includes people who identify as a member of one of the underrepresented groups in SUTx research using TBIs. We further seek to explore whether this subset of research is race/ethnicity conscious (does the research consider members of underrepresented groups beyond their inclusion as study participants in the introduction, methods, results, or discussion). Methods: Five electronic databases (MEDLINE, Scopus, Cochrane Library, CINAHL, and PsycInfo) were searched to identify SUTx research using TBIs, and studies were screened for eligibility at the title/abstract and full-text levels. Studies were included if their sample comprised of people who identify as a member of one of the underrepresented groups at 50% or more when combined. Results: Title/abstract and full-text reviews were completed in 2021. These efforts netted a sample of 185 studies that appear to meet inclusionary criteria. Due to the uniqueness of tobacco relative to other substances in the SUTx space, as well as the large number of studies netted, we plan to separately publish a scoping review on tobacco-focused studies that meet all other criteria. Filtering for tobacco-focused studies (n=31) netted a final full-text sample for a main scoping review of 154 studies. The tobacco-focused scoping review manuscript is expected to be submitted for peer review in Spring 2022. The main scoping review data extraction and data validation to confirm the accuracy and consistency of data extraction across records was completed in March 2022. We expect to publish the main scoping review findings by the end of 2022. Conclusions: Research is needed to increase our understanding of the range and nature of TBIs being used in SUTx research studies with members of underrepresented groups. The planned scoping review will highlight research at this intersection to promote health equity. International Registered Report Identifier (IRRID): DERR1-10.2196/34508

Background: The majority of those living with HIV in the United States are men who have sex with men (MSM), and young, minority MSM account for more new HIV infections than any other group. HIV transmission can be reduced through detection and early treatment initiation or by starting pre-exposure prophylaxis (PrEP), but rates of testing are lower than recommended among MSM, and PrEP uptake has been slow. Although promoting HIV testing and PrEP uptake by placing advertisements on web-based platforms — such as social media websites and dating apps — is a promising approach for promoting HIV testing and PrEP, the relative effectiveness of HIV prevention advertising on common web-based platforms is underexamined. Objective: This study aims to evaluate the relative effectiveness of advertisements placed on 3 types of web-based platforms (social media websites, dating apps, and informational websites) for promoting HIV self-testing and PrEP uptake. Methods: Advertisements will be placed on social media websites (Facebook, Instagram, and Twitter), dating apps (Grindr, Jack’d, and Hornet), and informational search websites (Google, Yahoo, and Bing) to recruit approximately 400 young (18-30 years old), minority (Black or Latino) MSM at elevated risk of HIV exposure. Recruitment will occur in 3 waves, with each wave running advertisements on 1 website from each type of platform. The number of participants per platform is not prespecified, and recruitment in each wave will occur until approximately 133 HIV self-tests are ordered. Participants will complete a baseline survey assessing risk behavior, substance use, psychological readiness to test, and attitudes and then receive an electronic code to order a free home-based HIV self-test kit. Two follow-ups are planned to assess HIV self-test results and PrEP uptake. Results: Recruitment was completed in July 2020. Conclusions: Findings may improve our understanding of how the platform users’ receptivity to test for HIV differs across web-based platforms and thus may assist in facilitating web-based HIV prevention campaigns.
