Abstinence beliefs in early adolescence and sexual risk behavior two years later.

INTRODUCTION: The United States has the highest teen pregnancy rate and sexually transmitted infection rates among developed countries. One common approach that has been implemented to reduce these rates is abstinence-only-until-marriage programs that advocate for delaying sexual intercourse until marriage. These programs focus on changing adolescents' beliefs toward abstinence until marriage; however, it is unclear whether adolescents' beliefs about abstinence predict their sexual behavior, including sexual risk behavior (SRB). An alternative approach may be encouraging youth to delay their sexual debut until they reach the age of maturity, but not necessarily until marriage. METHODS: To address this question, we compare the longitudinal association between abstinence beliefs (i.e., abstaining completely until marriage) and beliefs about delayed sexual debut with subsequent SRB 24 months later. The harmonized data set included 4620 (58.2% female, Mage = 13.0, SDage = 0.93) participants from three randomized controlled trials attending 44 schools in the southern United States. Negative binomial regressions were employed to examine the association of abstinence until marriage beliefs and beliefs regarding delaying sex with SRB. RESULTS: We identified that beliefs supporting delaying sex until an age of maturity were associated with lower odds of engaging in SRB, such as having multiple sex partners and frequency of condomless sex, for both sexes. However, stronger abstinence beliefs had no significant associations with all SRB outcomes. CONCLUSIONS: Findings suggest prevention programming that focuses on encouraging youth to delay sex until an appropriate age of maturity may be more effective at preventing SRB and consequent negative sexual health outcomes.

Sexual violence in early adolescence is associated with subsequent teen pregnancy and parenthood.

Being a victim of sexual violence (SV) is associated with risk for teen pregnancy in cross-sectional research. However, longitudinal data are necessary to determine if SV victimization plays a causal role in early pregnancy. To address this gap in research, we test whether experiencing SV victimization in early adolescence is associated with pregnancy and having children by mid-adolescence. The current sample comprised 4594 youth (58% female; 51% Hispanic; 39% Black) attending 44 schools in the southern United States. Self-reported data were collected via audio computer-assisted self-interview (ACASI) when students were in 7th or 8th grade and again approximately 24 months later. Approximately 2.9% of boys and 8.2% of girls reported SV victimization at baseline. At follow-up, 3.4% of boys and 4.0% of girls reported being involved with one or more pregnancies; 1.1% of boys and girls reported having one or more children. Being a victim of SV at baseline was associated with pregnancy and having a child at follow-up for girls. SV was not related to outcomes among boys. The present findings indicate that girls victimized by SV are at risk of becoming pregnant and becoming teen parents. The combined sequelae of SV and teen pregnancy impair health, economic, and social functioning across the lifespan and carry forward into future generations. Future research should explore mechanisms through which victimization confers risk for pregnancy to inform prevention strategies.

Inconsistencies in Adolescent Self-Reported Sexual Behavior: Experience from Four Randomized Controlled Trials.

To examine the degree, correlates, and implications of inconsistent self-report data on sexual risk behaviors of adolescents. We analyzed data from four longitudinal group-randomized controlled trials of evidence-based HIV/STI/pregnancy prevention programs in Texas and California from 2000 to 2010. Across- and within-time logical inconsistencies in sexual behavior survey responses were analyzed using multilevel logistic regression. Rates of any inconsistencies ranged from 12 to 18% across the four trials. In all trials, rates were higher in males than in females. Age, normative beliefs, and race/ethnicity were most strongly associated with inconsistencies. We found substantial rates of inconsistencies in adolescents' self-reports of their sexual behavior, which did not occur at random. Studies should routinely report observed rates of inconsistencies and methods used to adjust for them so that any biases in the population to which the study generalizes are understood by public health practitioners and policy-makers looking to adopt programs for their particular population.

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.

Replication of It's Your Game Keep It Real! in Southeast Texas.

Despite the recent efforts of the Office of Adolescent Health to replicate programs with demonstrated efficacy, there are still few evidence-based HIV, sexually transmitted infection (STI), and teen pregnancy prevention programs that have been replicated in "real-world" settings. To test the effectiveness of It's Your Game…Keep It Real! (IYG), an evidence-based STI and pregnancy prevention program for middle schools, the curriculum was implemented by teachers in urban and suburban middle schools in Southeast Texas from 2012 to 2015. IYG was evaluated using a group-randomized wait-list controlled effectiveness trial design in which 20 middle schools in nine urban and suburban school districts in Southeast Texas were randomized equally, using a multi-attribute randomization protocol, to either the intervention condition (received IYG) (n = 10 schools comprising 1936 eligible seventh graders) or the comparison condition (received usual care) (n = 10 schools comprising 1825 eligible seventh graders). All students were blinded to condition prior to administering the baseline survey. The analytic sample comprised 1543 students (n = 804, intervention; n = 739, comparison) who were followed from baseline (seventh grade) to the 24-month follow-up (ninth grade). Multilevel regression analyses were conducted to assess behavioral and psychosocial outcomes at follow-up. There were no significant differences in initiation of vaginal or oral sex between study conditions at follow-up. However, at 12-month follow-up, compared with students in the comparison condition, students in the intervention condition reported increased knowledge, self-efficacy, and perceived favorable norms related to HIV/STIs, condoms, and/or abstinence; decreased intentions to have sex; and increased intentions to use birth control. Knowledge outcomes were statistically significant at 24-month follow-up. This IYG effectiveness trial did not replicate the behavioral effects of the original IYG efficacy trials. However, it adds to the growing literature on the replication of evidence-based programs, and underscores the need to better understand how variations in implementation, setting, and measurement affect the behavioral impact of such programs.Clinical trial registration clinicaltrials.gov (NCT03533192).

Prevalence and Correlates of the Perpetration of Cyber Dating Abuse among Early Adolescents.

Much is known about the prevalence and correlates of dating violence, especially the perpetration of physical dating violence, among older adolescents. However, relatively little is known about the prevalence and correlates of the perpetration of cyber dating abuse, particularly among early adolescents. In this study, using a predominantly ethnic-minority sample of sixth graders who reported ever having had a boyfriend/girlfriend (n = 424, 44.2 % female), almost 15 % reported perpetrating cyber dating abuse at least once during their lifetime. Furthermore, using a cross-sectional design, across multiple levels of the socio-ecological model, the individual-level factors of (a) norms for violence for boys against girls, (b) having a current boyfriend/girlfriend, and (c) participation in bullying perpetration were correlates of the perpetration of cyber dating abuse. Collectively, the findings suggest that dating violence interventions targeting these particular correlates in early adolescents are warranted. Future studies are needed to establish causation and to further investigate the relative importance of correlates of the perpetration of cyber dating abuse among early adolescents that have been reported among older adolescents.

Effects of the It's Your Game . . . Keep It Real program on dating violence in ethnic-minority middle school youths: a group randomized trial.

OBJECTIVES: We examined whether It's Your Game . . . Keep It Real (IYG) reduced dating violence among ethnic-minority middle school youths, a population at high risk for dating violence. METHODS: We analyzed data from 766 predominantly ethnic-minority students from 10 middle schools in southeast Texas in 2004 for a group randomized trial of IYG. We estimated logistic regression models, and the primary outcome was emotional and physical dating violence perpetration and victimization by ninth grade. RESULTS: Control students had significantly higher odds of physical dating violence victimization (adjusted odds ratio [AOR] = 1.52; 95% confidence interval [CI] = 1.20, 1.92), emotional dating violence victimization (AOR = 1.74; 95% CI = 1.36, 2.24), and emotional dating violence perpetration (AOR = 1.58; 95% CI = 1.11, 2.26) than did intervention students. The odds of physical dating violence perpetration were not significantly different between the 2 groups. Program effects varied by gender and race/ethnicity. CONCLUSIONS: IYG significantly reduced 3 of 4 dating violence outcomes among ethnic-minority middle school youths. Although further study is warranted to determine if IYG should be widely disseminated to prevent dating violence, it is one of only a handful of school-based programs that are effective in reducing adolescent dating violence behavior.

Self-Efficacy to Refuse Sex Mediates the Relationship Between Dating Violence Victimization and Sexual Risk Behavior.

PURPOSE: While cross-sectional studies have shown that teen dating violence (TDV) victimization is linked to sexual risk behavior (SRB), the pathway between these variables is not well-understood. To address this knowledge gap, we explore the mediating role of self-efficacy to refuse sex in the longitudinal relationship between physical TDV victimization and subsequent SRB among adolescents. METHODS: Self-report data from three prior longitudinal studies were harmonized to create a single aggregated sample of primarily racial and ethnic minority adolescents (N = 4,620; 51.4% Hispanic, 38.5% Black, and 58% female) from 44 schools in the southwest U.S. Participants' physical TDV victimization at baseline (seventh and eighth grade), self-efficacy to refuse sex at 12-month follow-up, and SRB at 24-month follow-up was tested using mediation models with bias corrected bootstrapped confidence intervals. All regression models controlled for age, race, parental education, SRB at baseline, and intervention status. RESULTS: Physical TDV victimization at baseline was associated with refusal self-efficacy at 12 months and SRB (e.g., frequency of vaginal and oral sex, lifetime number of vaginal sex partners, and number of vaginal sex partners in the past three months without condom use) at 24 months. Refusal self-efficacy mediated the link between physical TDV victimization and increased risk of SRB for females and males, to a lesser extent. DISCUSSION: Adolescent victims of physical TDV report diminished self-efficacy to refuse sex, predisposing them to engage in SRBs, including condomless sex.

Sexual violence against sexual minority women in STEM: Compound backlash.

BACKGROUND: Recent research has found that gender parity (i.e., the ratio of women to men) in Science, Technology, Engineering, and Math (STEM) disciplines is associated with sexual violence (SV) victimization for women. This finding may reflect a type of backlash wherein SV is a means of punishing women who are perceived to be violating their gender roles and threatening the male hegemony. Sexual minorities, who are likewise disproportionately victims of SV, report experiencing heterosexist hostility and harassment in STEM disciplines. There is reason to suspect that the combination of these marginalized identity positions (e.g., a sexual minority woman in gender-balanced STEM) may amplify perceived gender role violations and exacerbate the risk of SV victimization. METHODS: Data were collected from undergraduate women at five institutions of higher education in the United States. Sampling was stratified by STEM vs. non-STEM majors and male-dominated vs. gender-balanced majors. Sexual violence was measured via the revised Sexual Experiences Survey. We tested the interaction of sexual minority status and gender parity in STEM on SV via fixed effects OLS regression. RESULTS: Sexual minority women in gender-balanced STEM were most frequently victims of SV. Women in male-dominated STEM majors were at no greater risk of SV victimization, regardless of sexual minority status, than their peers in non-STEM majors. IMPLICATIONS: These findings suggest the possibility of a compound form of backlash, wherein women are exponentially victimized because their sexual identity and their membership in these STEM fields are seen as dual challenges to the male hegemony. If true, this could exacerbate health disparities rather than promote health equity for these sexual minority women. Findings point to the ongoing need to challenge hegemonic gender norms, focus prevention programs on populations most at risk, and ensure they are provided the appropriate resources for support.

Economic Evaluation of an Intervention to Prevent Adolescent Dating Violence (Me & You).

Me & You: Building Healthy Relationships (Me & You) is a multilevel, technology-enhanced adolescent dating violence (DV) prevention program that aimed to reduce DV among ethnic-minority, early adolescent, urban youth. A group-randomized control trial of Me & You, conducted with 10 middle schools from a large urban school district in Southeast Texas in 2014-2015, found it to be effective in reducing DV perpetration and decreasing some forms of DV victimization. Economic evaluations of DV interventions are extremely limited, despite calls for more economic analyses to be incorporated in research. We help fill this gap by evaluating the cost-effectiveness from the payer and societal perspectives of implementing the Me & You program. Using cost data collected alongside the Me & You group-randomized trial, we computed incremental cost-effectiveness ratios. Our primary outcome was "any DV perpetrated" within 12 months of the intervention. We conducted a cost-benefit analysis beyond the intervention endpoint by using literature estimates of per-victim lifetime costs of DV. We performed sensitivity analyses to assess effects of uncertain parameters. Under the base-case scenario, the cost of the Me & You curriculum compared to the standard curriculum was $103.70 per-student from the societal perspective, and the effectiveness was 34.84 perpetrations averted, implying an incremental cost per perpetration averted of $2.98, which ranged from $0.48 to $73.24 in sensitivity analysis. Thus, we find the Me & You curriculum is cost-effective and cost-saving in most scenarios. Policymakers should carefully consider school-based DV prevention programs, and cost data should be regularly collected in adolescent prevention program evaluations.

The longitudinal association between sexual violence victimization and sexual risk behavior in adolescence.

Being a victim of sexual violence (SV) is generally believed to be associated with subsequent sexual risk behavior (SRB) during adolescence. While this assumption makes intuitive sense, it is based on methodologically limited research, including a reliance on cross-sectional data. To address this gap in research, we test whether experiencing SV victimization in early adolescence is associated with self-reported SRB approximately two years later. The sample comprised 4,618 youth (58% female; 52% Hispanic; 39% Black) attending 44 schools in the southern United States. Self-reported data were collected using an audio computer-assisted self-interview (ACASI). Baseline data were collected when students were in 7th or 8th grade and follow-up data were collected approximately 24 months later when students were in 9th or 10th grade. Indices of SRB included behaviors related to oral, vaginal, and anal sex (e.g., number of partners, number of times without a condom). Girls, but not boys, who reported SV victimization at baseline reported engaging more frequently in all oral and vaginal SRBs at 24 month follow-up compared to their non-victimized female counterparts. Additionally, girls reporting SV victimization reported more anal sex partners than non-victimized girls. Girls who are victims of SV engage in significantly more SRB by early high school placing them at greater risk to contract STIs and become pregnant. Victims of SV should be screened for SRB and provided access to the appropriate resources. Teen pregnancy and STI prevention planning should consider SV victimization in their strategy planning.

Socio-Ecological Factors Associated With Students' Perceived Impact of an Evidence-Based Sexual Health Education Curriculum.

BACKGROUND: Although schools often implement evidence-based sexual health education programs to address sexual and reproductive health disparities, multiple factors may influence program effectiveness. METHODS: Using student-reported perceived impact measures as a proxy for program effectiveness, we employed a socio-ecological approach to examine student, teacher, school, and district factors associated with greater perceived impact of It's Your Game (IYG), an evidence-based middle school sexual health education program. The student sample was 58.7% female, 51.8% Hispanic, mean age 13.2 years, from 73 middle schools. We assessed students' (N = 4531) perceived impact of IYG on healthy decision-making (α = 0.75) and sexual communication (α = 0.71); satisfaction with IYG activities and teacher; and demographics. We assessed teachers' (N = 56) self-efficacy to teach IYG, perceived administrative support, implementation barriers, and demographics. School and district data were abstracted from state records. We used multilevel logistic regression to estimate associations between independent variables and student-reported perceived impact. RESULTS: In final multivariate models, students' demographics (sex, ß = 0.06, SE = 0.015), satisfaction with IYG (ß = 0.21, SE = 0.012), and their IYG teacher (ß = 0.18, SE = 0.013) (all p = .000) were significantly associated with perceived impact on healthy decision-making. Similar findings resulted for sexual communication. No other variables were significantly associated with perceived impact. CONCLUSIONS: Helping schools select age-appropriate, culturally relevant programs, and facilitate supportive learning environments may enhance the perceived impact of sexual health education programs.

Safer choices 2: rationale, design issues, and baseline results in evaluating school-based health promotion for alternative school students.

BACKGROUND: Students attending 'alternative' high schools form relatively small, highly mobile high-risk populations, presenting challenges for the design and implementation of HIV-, other STI-, and pregnancy-prevention interventions. This paper describes the rationale, study design, and baseline results for the Safer Choices 2 program. STUDY DESIGN: Modified group-randomized intervention trial with cross-over of schools but not of students. The study cohort was defined a priori as those who completed the baseline measures and were still enrolled at the time of first follow-up. DESIGN RESULTS: Of 940 students initially enrolled in the study, 711 (76%) formed the study cohort. There were significant demographic differences between those included and those excluded from the study cohort in sex, age, sexual experience, experience with pregnancy, drug use, and some psychosocial measures. There were no significant differences between the intervention and control groups within the study cohort. The only significant difference between those students excluded from the intervention group and those excluded from the control group was reported age at first intercourse. BASELINE DATA RESULTS: Students (n=940) enrolled were predominately African-American (29.7%) and Hispanic (61.3%); 57.3% were female; 66% had ever had sex; and reported drug use in the previous 30 days ran from 4.3% (cocaine) to 26.9% (marijuana). Of the 627 sexually experienced, 41.8% reported their age at first intercourse as 13 years or younger; 28.5% reported ever being or having gotten someone pregnant; 74% reported sex in the past 3 months. Of the 464 sexually active in the last 3 months, 55.4% reported unprotected intercourse and 31.3% reported using drugs beforehand. CONCLUSION: The cross-over design will provide a rigorous test of the intervention; however, loss to follow-up of this population can result in some selection bias. Students attending dropout prevention and recovery schools are at high risk for HIV, STIs, and pregnancy, and are in need of interventions.

Estimates of Intraclass Correlation Coefficients From Longitudinal Group-Randomized Trials of Adolescent HIV/STI/Pregnancy Prevention Programs.

INTRODUCTION: Group-randomized trials (GRTs) are one of the most rigorous methods for evaluating the effectiveness of group-based health risk prevention programs. Efficiently designing GRTs with a sample size that is sufficient for meeting the trial's power and precision goals while not wasting resources exceeding them requires estimates of the intraclass correlation coefficient (ICC)-the degree to which outcomes of individuals clustered within groups (e.g., schools) are correlated. ICC estimates vary widely depending on outcome, population, and setting, and small changes in ICCs can have large effects on the sample size needed to estimate intervention effects. This study addresses a gap in the literature by providing estimates of ICCs for adolescent sexual risk-taking outcomes under a range of study conditions. METHOD: Multilevel regression analyses were applied to existing data from four federally funded GRTs of school-based HIV/STI/pregnancy prevention programs to obtain a variety of ICC estimates. RESULTS: ICCs ranged from 0 to 0.15, with adjustment for covariates and repeated measurements reducing the ICC in the majority of cases. Minimum detectable effect sizes with 80% power and 0.05 significance levels ranged from small to medium Cohen's d (0.13 to 0.53) assuming 20 schools of 100 students each. CONCLUSIONS: This study provides the first known set of ICC estimates for investigators to use when planning studies of school-based programs to prevent sexual risk behaviors in youth. The results provide further evidence of the importance of using the appropriate adjusted ICC estimate at the design stage to maximize resources in costly GRTs.

Efficacy of It's Your Game-Tech: A Computer-Based Sexual Health Education Program for Middle School Youth.

PURPOSE: Few computer-based HIV, sexually transmitted infection (STI), and pregnancy prevention programs are available, and even fewer target early adolescents. In this study, we tested the efficacy of It's Your Game (IYG)-Tech, a completely computer-based, middle school sexual health education program. The primary hypothesis was that students who received IYG-Tech would significantly delay sexual initiation by ninth grade. METHODS: We evaluated IYG-Tech using a randomized, two-arm nested design among 19 schools in a large, urban school district in southeast Texas (20 schools were originally randomized). The target population was English-speaking eighth-grade students who were followed into the ninth grade. The final analytic sample included 1,374 students. Multilevel logistic regression models were used to test for differences in sexual initiation between intervention and control students, while adjusting for age, gender, ethnicity, time between measures, and family structure. RESULTS: There was no significant difference in the delay of sexual activity or in any other sexual behavior between intervention and control students. However, there were significant positive between-group differences for psychosocial variables related to STI and condom knowledge, attitudes about abstinence, condom use self-efficacy, and perceived norms about sex. Post hoc analyses conducted among intervention students revealed some significant associations: "full exposure" (completion of all 13 lessons) and "mid-exposure" (5-8 lessons) students were less likely than "low exposure" (1-4 lessons) students to initiate sex. CONCLUSIONS: Collectively, our findings indicate that IYG-Tech impacts some determinants of sexual behavior, and that additional efficacy evaluation with full intervention exposure may be warranted.

Factors Associated With Early Sexual Experience Among American Indian and Alaska Native Youth.

PURPOSE: American Indian and Alaska Native (AI/AN) youth experience disparities associated with sexual and reproductive health, including early age of sexual initiation. Identifying factors that are most proximally related to early sexual intercourse and that are modifiable through health promotion interventions may help to reduce these disparities. Using a multisystem approach, we assessed individual (biological, psychological, and behavioral), familial, and extrafamilial (peer behavioral) factors associated with lifetime sexual experience among AI/AN early adolescents living in three geographically dispersed U.S. regions. METHODS: We analyzed cross-sectional data from 537 AI/AN youth aged 12-14 years, recruited from 27 study sites in Alaska, Arizona, and the Pacific Northwest. We used multilevel logistic regression models to estimate associations between independent variables and lifetime sexual intercourse (oral and/or vaginal sex) individually, within discrete systems, and across systems. RESULTS: The analytical sample was 55.1% female, with a mean age of 13.2 years (standard deviation = 1.06 years); 6.5% were sexually experienced. In the final model, we found that lower next-year intentions to have oral or vaginal sex (psychological factors), avoidance of risky situations, and nonuse of alcohol (behavioral factors) were associated with lower odds of lifetime sexual intercourse (all p ≤ .01). No other variables were significantly associated with lifetime sexual intercourse. CONCLUSIONS: Interventions that reduce sexual intentions, exposure to risky situations, and alcohol use may help to delay sexual initiation among AI/AN early adolescents.

Behavioral and psychosocial effects of two middle school sexual health education programs at tenth-grade follow-up.

PURPOSE: An earlier randomized controlled trial found that two middle school sexual education programs-a risk avoidance (RA) program and a risk reduction (RR) program-delayed initiation of sexual intercourse (oral, vaginal, or anal sex) and reduced other sexual risk behaviors in ninth grade. We examined whether these effects extended into 10th grade. METHODS: Fifteen middle schools were randomly assigned to RA, RR, or control conditions. Follow-up surveys were conducted with participating students in 10th grade (n = 1,187; 29.2% attrition). RESULTS: Participants were 60% female, 50% Hispanic, and 39% black; seventh grade mean age was 12.6 years. In 10th grade, compared with the control condition, both programs significantly delayed anal sex initiation in the total sample (RA: adjusted odds ratio [AOR], .64, 95% confidence interval [CI], .42-.99; RR: AOR, .65, 95% CI, .50-.84) and among Hispanics (RA: AOR, .53, 95% CI, .31-.91; RR: AOR, .82, 95% CI, .74-.93). Risk avoidance students were less likely to report unprotected vaginal sex, either by using a condom or by abstaining from sex (AOR: .61, 95% CI, .45-.85); RR students were less likely to report recent unprotected anal sex (AOR: .34, 95% CI, .20-.56). Both programs sustained positive impact on some psychosocial outcomes. CONCLUSIONS: Although both programs delayed anal sex initiation into 10th grade, effects on the delayed initiation of oral and vaginal sex were not sustained. Additional high school sexual education may help to further delay sexual initiation and reduce other sexual risk behaviors in later high school years.

Daily violent video game playing and depression in preadolescent youth.

Most studies on the impact of playing violent video games on mental health have focused on aggression. Relatively few studies have examined the relationship between playing violent video games and depression, especially among preadolescent youth. In this study, we investigated whether daily violent video game playing over the past year is associated with a greater number of depressive symptoms among preadolescent youth, after controlling for several well-known correlates of depression among youth. We analyzed cross-sectional data collected from 5,147 fifth-grade students and their primary caregivers who participated in Wave I (2004-2006) of Healthy Passages, a community-based longitudinal study conducted in three U.S. cities. Linear regression was conducted to determine the association between violent video game exposure and number of depressive symptoms, while controlling for gender, race/ethnicity, peer victimization, witnessing violence, being threatened with violence, aggression, family structure, and household income level. We found that students who reported playing high-violence video games for ≥2 hours per day had significantly more depressive symptoms than those who reported playing low-violence video games for <2 hours per day (p<0.001). The magnitude of this association was small (Cohen's d=0.16), but this association was consistent across all racial/ethnic subgroups and among boys (Cohen's d values ranged from 0.12 to 0.25). Our findings indicate that there is an association between daily exposure to violent video games and number of depressive symptoms among preadolescent youth. More research is needed to examine this association and, if confirmed, to investigate its causality, persistence over time, underlying mechanisms, and clinical implications.

Sexual risk avoidance and sexual risk reduction interventions for middle school youth: a randomized controlled trial.

PURPOSE: To evaluate the efficacy of two, theory-based, multimedia, middle school sexual education programs in delaying sexual initiation. METHODS: Three-armed, randomized controlled trial comprising 15 urban middle schools; 1,258 predominantly African American and Hispanic seventh grade students followed into ninth grade. Both programs included group and individualized, computer-based activities addressing psychosocial variables. The risk avoidance (RA) program met federal abstinence education guidelines; the risk reduction (RR) program emphasized abstinence and included computer-based condom skills-training. The primary outcome assessed program impact on delayed sexual initiation; secondary outcomes assessed other sexual behaviors and psychosocial outcomes. RESULTS: Participants were 59.8% females (mean age: 12.6 years). Relative to controls, the RR program delayed any type of sexual initiation (oral, vaginal, or anal sex) in the overall sample (adjusted odds ratio [AOR]: .65, 95% CI: .54-.77), among females (AOR: .43, 95% CI: .31-.60), and among African Americans (AOR: .38, 95% CI: .18-.79). RR students also reduced unprotected sex at last intercourse (AOR: .67, 95% CI: .47-.96), frequency of anal sex in the past 3 months (AOR: .53, 95% CI: .33-.84), and unprotected vaginal sex (AOR: .59, 95% CI: .36-.95). The RA program delayed any sexual initiation among Hispanics (AOR: .40, 95% CI: .19-.86), reduced unprotected sex at last intercourse (AOR: .70, 95% CI: .52-.93), but increased the number of recent vaginal sex partners (AOR: 1.69, 95% CI: 1.01-2.82). Both programs positively affected psychosocial outcomes. CONCLUSIONS: The RR program positively affected sexually inexperienced and experienced youth, whereas the RA program delayed initiation among Hispanics and had mixed effects among sexually experienced youth.

It's Your Game: Keep It Real: delaying sexual behavior with an effective middle school program.

PURPOSE: This study tested the effects of a theory-based, middle-school human immunodeficiency virus, STI, and pregnancy prevention program, It's Your Game: Keep it Real (IYG), in delaying sexual behavior. We hypothesized that the IYG intervention would decrease the number of adolescents who initiated sexual activity by the ninth grade compared with those in the comparison schools. METHODS: The target population consisted of English-speaking middle school students from a large, urban, predominantly African-American and Hispanic school district in Southeast Texas. Ten middle schools were randomly assigned either to receive the intervention or to the comparison condition. Seventh-grade students were recruited and followed through ninth grade. The IYG intervention comprises 12 seventh-grade and 12 eighth-grade lessons that integrate group-based classroom activities with computer-based instruction and personal journaling. Ninth-grade follow-up surveys were completed by 907 students (92% of the defined cohort). The primary hypothesis tested was that the intervention would decrease the number of adolescents who initiated sexual activity by the ninth grade compared with those in the comparison schools. RESULTS: Almost one-third (29.9%, n=509) of the students in the comparison condition initiated sex by ninth grade compared with almost one-quarter (23.4%, n=308) of those in the intervention condition. After adjusting for covariates, students in the comparison condition were 1.29 times more likely to initiate sex by the ninth grade than those in the intervention condition. CONCLUSIONS: A theory-driven, multi-component, curriculum-based intervention can delay sexual initiation up to 24 months; can have impact on specific types of sexual behavior such as initiation of oral and anal sex; and may be especially effective with females. Future research must explore the generalizabilty of these results.
