Stability of alcohol use and teen dating violence for female youth: A latent transition analysis

Longitudinal examination of marijuana use and physical teen dating violence: Antisocial peers and impulsivity as mediators

BACKGROUND

Prior studies have shown that marijuana use is often associated with physical teen dating violence. However, few studies have examined the longitudinal mediating effects of associating with antisocial peers and impulsivity on this relationship. Also, few studies have estimated the cascading developmental impact of marijuana use and antisocial peer association, predicting the continued marijuana use and antisocial peer associations while considering the risk of impulsivity in physical teen dating violence. Thus, the current study utilized the problem behavior theory and an alternative path to physical dating violence to address these limitations.

OBJECTIVE

The current study tested the longitudinal effects of marijuana use on physical teen dating violence and the indirect effects of antisocial peer association and impulsivity on this relationship (M = 12.29); 52.1 % of males and 47.9 % of females participated.

METHODS

Adolescents completed questionnaires at baseline and were assessed six months later (n = 836). Generalized structural equation modeling (GSEM) and cross-lagged mediation models were used first to analyze the direct effect of lifetime marijuana use on physical dating violence and antisocial peer association and impulsivity as potential mediators of this relationship. Then, the cross-lagged mediation models were used to estimate the alternative path to physical teen dating violence using lifetime marijuana use and antisocial peer association as predictors at baseline and continued antisocial peer association, marijuana use, and impulsivity at the subsequent wave as mediators.

RESULTS

Results suggested that marijuana use at baseline was not positively associated with physical teen dating violence over time. The association with antisocial peers but not impulsivity mediated the relationship between marijuana use and physical dating violence. Cross-lagged mediation results suggested that marijuana use at baseline positively predicted antisocial peer association in the subsequent wave, which led to an increase in physical teen dating violence. Further, antisocial peer association at baseline is positively associated with continued antisocial peer association at the subsequent wave; thus, antisocial peer association is positively related to physical teen dating violence when controlling for depressive symptoms, family support, number of dates, and parental monitoring.

CONCLUSION

These results suggest though marijuana use alone is not statistically associated with physical teen dating violence, it does increase the risk of antisocial social peer associations that could increase adolescents' likelihood to engage in physical teen dating violence. Further, the onset of antisocial peer association could persist over time, thus serving as a risk factor for physical teen dating violence over time.

Victims of drug facilitated sexual assault aged 13-24: a cross sectional study on the pool of users of a sexual violence relief centre in Northern Italy

This cross-sectional study aimed to assess the association between drugs and alcohol intake and sexual abuse in adolescents, otherwise defined as Drug Facilitated Sexual Assault (DFSA). We considered the survivors who accessed care at the Centre "Soccorso Violenza Sessuale" (SVS - Sexual Violence Relief Centre) in Turin (Italy), between May 2003 and May 2022. We found that 973 patients aged 13-24 among which 228 were victims of DFSA. Epidemiological and anamnestic aspects of the episode of sexual violence were examined, with a specific focus on investigating the alcohol and/or drug intake as reported by the victim, along with the results of the toxicological analysis. the study further accounts for the variations caused by the COVID-19 pandemic on DFSA-related accesses. Our findings show that 23% of adolescents accessing care at SVS were subjected to DFSA. Six out ten adolescents knew their aggressor, at times a partner (10%) oran acquaintance (43%). In 12% of cases violence was perpetrated by a group of people (12%). Almost 90% of young victims described alcohol consumption, while 37% reported drug use at the time of the assault. Alcohol taken alone or in combination with other substances was the most detected drug in our sample throughout the period considered. Given the large use of psychoactive substances among adolescents, it is imperative to implement harm reduction strategies alongside educational activities aimed at fostering awareness about consent. Health personnel should be trained to manage the needs of victims of DFSA clinically and forensically.

Longitudinal Associations Between Adolescent Dating Violence Victimization and Adverse Outcomes: A Systematic Review

Evidence on the outcomes of adolescent dating violence (ADV) victimization mainly derives from cross-sectional studies, which have limitations in suggesting causal relationships. Furthermore, the complexity of factors and overlapping dimensions in dating violence research, such as the forms of violence experienced, may have contributed to the variability of findings across the literature. To address these gaps and provide a more comprehensive understanding of the impact of ADV, this study reviews findings from prospective cohort studies, with a focus on the type of violence experienced and the gender of the victim. A systematic search was conducted in nine electronic databases and additional relevant journals. Prospective longitudinal studies were included if dating violence victimization occurred during adolescence and chronologically preceded the outcomes. A quality assessment was conducted using the Mixed Methods Appraisal Tool. A narrative approach was used to synthesize findings. After screening 1,838 records, 14 publications met the selection criteria and were included in this review. Our findings suggest that experiencing ADV is longitudinally associated with many adverse outcomes, including higher internalizing symptoms and externalizing behaviors, poorer well-being, increased substance use, and increased revictimization. However, the associations are not consistently reported across studies when considering the type of ADV experienced and the gender of the victim. This review highlights the limited number of longitudinal studies examining the outcomes of ADV victimization, the unbalanced approach in investigating different forms of violence, and the lack of diverse samples examining this subject. Implications for research, policy, and practice are outlined.

Understanding Associations Between Exposure to Violent Pornography and Teen Dating Violence Among Female Sexual Minority High School Students

Previous research indicates that teen dating violence (TDV) is more common among sexual minority than heterosexual adolescents, with approximately half of female sexual minority adolescents (SMA) endorsing TDV victimization in the last year. In samples of adolescents without regard to sexual orientation, exposure to violent pornography is associated with TDV, but this relationship has not been assessed in female SMA. The current study sample consisted of 10th-grade high school students aged 14-17 who identified as cisgender females (N = 1,276). Data were collected from a baseline survey prior to the delivery of a sexual assault prevention intervention. Female SMA had 2.54 times the odds (95%CI [1.75, 3.69]) of being exposed to violent pornography and 2.53 times the odds (95%CI [1.72, 3.70)]) of TDV exposure compared to heterosexual girls. Exposure to violent pornography was not associated with involvement in TDV among female SMA, controlling for episodic heavy drinking (aOR = 2.25, 95%CI [0.88,6.22]).Given the relatively higher rates of violent pornography and TDV exposure among female SMA compared to heterosexual girls, it is critical that sex education curricula address these experiences and meet the needs of adolescents of all sexual orientations. Future research can assess how these TDV interventions might be tailored for female SMA. Although we did not find that exposure to violent pornography was associated with TDV among female SMA, these investigations should be replicated with larger data sets, given that the association between exposure to violent pornography and engagement in TDV was in the expected direction.

Attitudes are associated with the drug use profiles of middle school adolescents: A latent class analysis

The association between positive and negative attitudes and drug use profiles is examined. Participants were public middle school students (N = 5213; 49.9% girls; M age= 13.2 years) in three Brazilian cities. Analysis was performed using baseline surveys of a randomized controlled trial of the #Tamojunto2.0 drug use prevention program. We validated the attitudes construct via a confirmatory factor analysis and performed a simultaneous multinomial regression with a latent class analysis. Three latent classes were identified: abstainers/low users (ABS) (63.4%), alcohol users/binge drinkers (ALC) (29.5%), and polydrug users (POL) (7.1%). An association gradient was found between attitudes and latent classes. Using ABS as reference, a direct association was identified between positive attitudes and ALC and POL. An inverse association was found between negative attitudes and POL only. Girls and older students were more likely to be ALC and POL. These findings, from a large probabilistic sample, provide guidance that drug use prevention programs should focus on deconstructing positive attitudes -mainly- and broadening negative attitudes, and should adapt their thematic content by considering the differential drug use possibilities among girls and older students.

Predicting latent classes of drug-related problems among adolescents: secondary analysis of a cluster randomized controlled trial

Objective:

To detect latent patterns of drug-related problems and their predictors among adolescents.

Methods:

A three-wave randomized controlled trial was conducted among 6,391 7th and 8th graders (51.02% girls) at 72 public schools in six Brazilian cities to evaluate the #Tamojunto school-based drug prevention program. Patterns of drug use and behavior problems were identified through latent class analysis, and logistic regression analyses were used to detect predictors of high-risk and low-risk groups.

Results:

Two groups were found that best explained the patterns of drug use and problem behaviors: high drug use/high problems and low drug use/low problems, representing 36.7 and 63.3% of the sample, respectively. No program effect was a determinant of the risk of belonging to these groups. Any reported problem behavior in the year preceding baseline assessment increased the likelihood of belonging to the high-risk group at the 21-month follow-up by 16 times. Alcohol use at baseline and female gender increased the likelihood of belonging to the high-risk group by 70%.

Conclusion:

Previous behavior problems and alcohol use were the strongest predictors of higher risk, suggesting that effective earlier interventions and early screening for alcohol use and behavioral problems are needed at schools, particularly for girls.

Patterns of substance use before and after hospitalization among patients seen by an inpatient addiction consult service: A latent transition analysis

BACKGROUND AND AIMS

Polysubstance use is common and contributes to morbidity and mortality of hospitalized patients, and yet little is known about patterns of substance use among hospitalized patients, or how an addiction consult service (ACS) might impact polysubstance use after discharge. The objective of this study was to identify patterns of substance use at admission and after discharge among hospitalized patients with substance use disorders who saw an ACS.

DESIGN

Prospective cohort study. We used latent transition analysis of substance use scores at the time of hospital admission and 30 to 90 days posthospitalization.

SETTING

Single, academic health center with an ACS in Portland, Oregon, from 2015 to 2018.

PARTICIPANTS/CASES

Patients were eligible if they received a consult to the inpatient ACS.

MEASUREMENTS

We used Addiction Severity Index-Lite scores to capture self-reported substance use at baseline and follow-up for heroin, other opioid, alcohol, amphetamine, and cocaine.

FINDINGS

From 2015 to 2018, 486 individuals consented to participate. More than half of patients used more than one substance at baseline. Of those reporting any baseline opioid use, nearly three-quarters (n=187, 69.5%) had polysubstance use in the previous 30 days, including alcohol (n=80, 29.7%), cocaine (n=25, 9.3%), or amphetamine use (n=142, 52.8%). We identified three patterns of substance use at baseline: 1) alcohol use dominant, 2) polysubstance use dominant, and 3) heroin and other opioid use dominant. Patients transitioned along five trajectories to three different follow-up profiles that showed lower endorsement of all substances used. Slightly more than 40% (40.1%) of patients newly endorsed abstinence of at least one substance at follow-up.

CONCLUSIONS

Polysubstance use is common in hospitalized patients with substance use disorders and identifying patterns of polysubstance use can guide clinical management. Hospital providers should prepare to manage polysubstance use during hospitalization and hospitals should broaden care beyond interventions for opioid use disorder.

Adolescent Dating Violence Prevention Program for Early Adolescents: The Me & You Randomized Controlled Trial, 2014-2015

Objectives. To test the efficacy of Me & You, a multilevel technology-enhanced adolescent dating violence (DV) intervention, in reducing DV perpetration and victimization among ethnic-minority early adolescent youths. We assessed secondary impact for specific DV types and psychosocial outcomes.Methods. We conducted a group-randomized controlled trial of 10 middle schools from a large urban school district in Southeast Texas in 2014 to 2015. We used multilevel regression modeling; the final analytic sample comprised 709 sixth-grade students followed for 1 year.Results. Among the total sample, odds of DV perpetration were lower among intervention students than among control students (adjusted odds ratio = 0.46; 95% confidence interval = 0.28, 0.74). Odds of DV victimization were not significantly different. There were significant effects on some specific DV types.Conclusions. Me & You is effective in reducing DV perpetration and decreasing some forms of DV victimization in early middle-school ethnic-minority students.

Longitudinal Associations of Binge Drinking with Interpersonal Violence Among Adolescents

Binge drinking may be associated with adolescents' experience of multiple types of interpersonal violence perpetration and victimization, and if so, could be a malleable intervention target to prevent interpersonal violence. The current article explores the between- and within-person associations of binge drinking (i.e., 4/5 or more drinks in a row for girls/boys) with interpersonal violence among adolescents (N = 1322, 50.3% girls/women, 88.9% White/non-Hispanic, 85.9% heterosexual, 18.6% free/reduced lunch, aged 13-19) using a longitudinal design (three waves of data collection across more than a year). Overall, adolescents who engaged in binge drinking at more time points were more likely to perpetrate sexual harassment and stalking, and more likely to be victims of stalking and dating violence. At time points when adolescents had engaged in binge drinking in the past month, they were more likely to perpetrate dating violence, less likely to perpetrate stalking, and more likely to be sexual harassment victims. Addressing binge drinking in prevention programs may reduce some forms of interpersonal violence.

Problem Drinking, Alcohol-Related Violence, and Homelessness among Youth Living in the Slums of Kampala, Uganda

This paper examines problem drinking, alcohol-related violence, and homelessness among youth living in the slums of Kampala—an understudied population at high-risk for both alcohol use and violence. This study is based on a cross-sectional survey conducted in 2014 with youth living in the slums and streets of Kampala, Uganda (n = 1134), who were attending Uganda Youth Development Link drop-in centers. The analyses for this paper were restricted to youth who reported current alcohol consumption (n = 346). Problem drinking patterns were assessed among youth involved in alcohol-related violence. Mediation analyses were conducted to examine the impact of homelessness on alcohol-related violence through different measures of problem drinking. Nearly 46% of youth who consumed alcohol were involved in alcohol-related violence. Problem drinkers were more likely to report getting in an accident (χ² = 6.8, df = 1, p = 0.009), having serious problems with parents (χ² = 21.1, df = 1, p < 0.0001) and friends (χ² = 18.2, df = 1, p < 0.0001), being a victim of robbery (χ² = 8.8, df = 1, p = 0.003), and going to a hospital (χ² = 15.6, df = 1, p < 0.0001). For the mediation analyses, statistically significant models were observed for frequent drinking, heavy drinking, and drunkenness. Interventions should focus on delaying and reducing alcohol use in this high-risk population.
