Adverse Childhood Experiences and Substance Use
INTRODUCTION: While adverse childhood experiences (ACEs) are robust risk factors for adolescent substance use, the prospective neurocognitive pathways linking both cumulative and specific adversities to substance use remain understudied. This study tested a vulnerability model by examining whether executive function (EF) deficits mediate the link between cumulative and specific ACEs and substance use, and whether this pathway differs for deprivat…
Longitudinal Associations Between Early Noncoital Sexual and Romantic Behaviors and Adolescent Depressive Symptoms
INTRODUCTION: Research has linked early intercourse and romantic relationships to increased depressive symptoms, especially for female adolescents. However, less is known about the ways in which early noncoital sexual behaviors are associated with mental health. Thus, this study examined whether early kissing, sexual touching, and romantic relationships were associated with depressive symptoms, and whether these associations differed for male, fe…
Adverse Childhood Experiences and Adolescent Early Non-Coital Sexual and Relationship Behaviors
Adverse childhood experiences (ACEs) are linked with risky sexual behaviors. However, we do not know how various ACE dimensions influence adolescent sexual behavior, especially behaviors that are precursors to early sexual intercourse. Using the data from the Adolescent Brain and Cognitive Development Study, we conducted LCA on 13 ACE measures assessed at ages 9-11 and analyzed how these latent classes relate to romantic relationships and early n…
Early Non-Coital Sexual and Romantic Behaviors in Latine Adolescents
This secondary data analysis examined how adolescent early non-coital sexual and romantic behaviors and intentions vary by U.S. Latine origin (e.g., Cuban-, Dominican-, Mexican-, Puerto Rican-, Central and South American, and Other-origin), and explored whether these differences remained when accounting for demographic and cultural factors (e.g., familism). We used data from the baseline and Year 3 follow-ups of the Adolescent Brain Cognitive Dev…
Multidimensional profiles of adolescent social−ecological risk and protective factors and young adult sexual behavior
Research has demonstrated that social-ecological risk and protective factors at multiple levels are associated with sexual behavior in adolescence. However, relatively little is known about how different patterns of these factors may work together in combination to influence sexual risk. In this study, we use nationally representative data from the U.S. National Longitudinal Study of Adolescent to Adult Health to (a) uncover latent classes of ado…
A Scoping Review on Adverse Childhood Experiences Studies Using Latent Class Analysis
Adverse childhood experiences (ACEs) studies reveal the profound impacts of experiencing trauma and hardships in childhood. However, the cumulative risk approach of treating ACEs obscures the heterogeneity of ACEs and their consequences, making actionable interventions impossible. latent class analysis (LCA) has increasingly been used to address these concerns by identifying underlying subgroups of people who experience distinctive patterns of co…
Time‐varying associations between parental closeness, self‐esteem, and sexual behavior across adolescence and emerging adulthood
This study applied the time-varying effect model (TVEM) to data from the National Longitudinal Study of Adolescent to Adult Health to explore how self-esteem mediated age-varying associations of closeness to mother and father and their child's sexual behavior through adolescence and emerging adulthood. Paternal closeness is associated with lesser odds of sexual behaviors for both female and male adolescents until age 20, whereas maternal closenes…

Longitudinal Patterns of Multidimensional Violence Exposure and Adolescent Early Sexual Initiation
Associations between parental and adolescent alcohol use
INTRODUCTION: This study examined the role of gender and familism support in the associations between parental and adolescent drinking behaviors in a sample of Mexican adolescents. METHOD: Mexican adolescents (49% girls; N = 724) aged 12-19 completed measures assessing familism support, self-reported drinking behaviors, and perceptions of parental drinking behaviors. RESULTS AND CONCLUSION: Findings suggest that both gender and familism support m…
Religious Transitions Among Baby Boomers From Young Adulthood to Later Life
We used classification analysis to examine change in religiosity among baby boomers from young adulthood to early old age and how religiosity transition patterns are associated with psychological well-being in later life. In addition, we tested the gender difference in the above association. We applied latent class and latent transition analysis to 392 baby boomers who participated in the Longitudinal Study of Generations in Wave-1 (1971) and Wav…
Patterns of Sexual Well-Being in Mexican Adolescents and Associations with Psychological Adjustment
We examined Mexican adolescent sexual well-being tasks, defined as the positive cognitive and emotional evaluations of one's sexuality. We assessed three dimensions: acceptance of sexual desire, sexual decision-making involving mutual consent, and, when sexually active, the practice of safe sex. We utilized a person-centered approach to examine how patterns marked by different aspects of sexual well-being predict psychological adjustment. Partici…
Positive, Negative, or Mixed Feelings? A Person-Centered Approach to Consequences of First Penile-Vaginal Intercourse in College Students
An ecological latent class model of adolescent risk and protective factors
To provide a comprehensive view of the unique contexts shaping adolescent development in the U.S., we utilized latent class analysis (LCA) with indicators of risk and protection across multiple domains (family, peers, school, neighborhood) and examined how latent class membership predicted heavy episodic drinking, illicit substance use, and depression in adolescence and 6 years later when participants were young adults. Data came from Wave 1 (W1)…
Changes in psychological distress after first vaginal intercourse in late adolescence
INTRODUCTION: Although early sexual intercourse may be associated with increased depressive symptoms, little research has examined whether first intercourse in late adolescence is associated with changes in mental health. METHODS: This paper uses 3 years of longitudinal data from previously sexually abstinent late adolescent students at a large state university in the northeastern United States (N = 144, 53.5% male, M age = 18.5 years old, 47.2% …

Multidimensional Profiles of Religiosity Among Adolescents
Religiosity is associated with sexual behavior in adolescence; however, religiosity is a multidimensional construct, and it is not clear how different patterns of religiosity may differentially predict sexual behaviors and romantic relationships. We apply latent class analysis to nationally representative data from the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 10,149) to examine (1) what religiosity profiles exist…
Patterns of Sexual Behaviors in Young Men Who Have Sex With Men in Mexico
Recent research has documented the importance of understanding the multidimensional nature of sexual risk behavior. However, little is known about patterns of sexual behavior among men who have sex with men (MSM) in Mexico, men who are at greatest risk for HIV and sexually transmitted infections compared to other subpopulations in the country. This study applied latent class analysis to data from a large, HIV-negative sample of 18- to 25-year-old…
Sexual Behavior and Daily Affect in Emerging Adulthood
Although sexual behavior has been linked to mental health and well-being in adolescence and adulthood, relatively little is known about how sexual behavior is associated with well-being in emerging adulthood. This article uses data from college students ( N = 364; M age = 18.4; range = 16.9–20.8; 57.4% female; 29.1% Hispanic/Latino [HL], 25.0% non-HL European American, 17.3% non-HL Asian American, 17.0% non-HL African American, and 11.5% non-HL m…
Sociocultural Influences on the Association Between Negative Romantic Experiences and Psychological Maladjustment in Mexican Adolescents
The goal of this study was to examine whether cultural values (familismo, female virginity) and gender moderated the associations between negative romantic experiences and psychological maladjustment (depressive, anxiety symptoms) in a sample of Mexican adolescents. Self-report survey data were collected from 973 adolescents (M = 15.14 years old; 56% girls) in Mexico. Findings revealed more depressive and anxiety symptoms among adolescents who re…
Adolescent Age of Sexual Initiation and Subsequent Adult Health Outcomes
Objectives. To examine the mechanisms of the association between age of sexual initiation and adult health. Methods. Data from the Seattle Social Development Project (n = 808), in Seattle, Washington, included outcomes when participants were in their 30s (2005–2014): substance use disorders, depression, poor health, and obesity. Sexual consequence mediators included sexually transmitted infection, adolescent pregnancy, and a high number of sexual…
Changes in Diverse Sexual and Contraceptive Behaviors Across College
Researchers have made repeated calls for a better understanding of normative sexuality development during adolescence and young adulthood. We examined how the occurrence of seven penetrative, nonpenetrative, and contraceptive behaviors changed longitudinally across seven waves, and how individual (gender) and contextual (romantic relationship status) factors related to these changes in a sample of college students ( N = 730, M age = 18.4 at Semes…
A Dyadic Approach to Pornography Use and Relationship Satisfaction Among Heterosexual Couples
The majority of research on pornography use within committed relationships has found such use to be associated with negative outcomes. However, given the variability in pornography use among couples, the current study sought to examine moderators in the association between pornography use and relationship satisfaction in a large sample of heterosexual matched-paired couples (N = 6,626). Actor-partner interdependence models (APIMs) revealed that f…
Sexual Behavior and Heavy Episodic Drinking Across the Transition to Adulthood
Despite a growing literature on college students' sexual behaviors, little is known about how sexual behaviors, and their associations with alcohol, differ for college and noncollege attenders, and whether these patterns represent changes during college or an extension of pre-college behaviors. This paper applied time-varying effect models to data from the National Longitudinal Study of Adolescent to Adult Health to examine (1) prevalence of four…
Short-Term Positive and Negative Consequences of Sex Based on Daily Reports Among College Students
Because sexual behavior may be associated with a broader range of outcomes than physical consequences like sexually transmitted infections and pregnancy, it is important to understand consequences of sex that may influence mental and social well-being in emerging adulthood. This article describes the short-term intrapersonal and interpersonal consequences reported by college students on days they engage in vaginal sex and what factors predict exp…

It Felt Good but Weird at the Same Time”
Although sexual behavior is multidimensional, little research has focused on the experience of non-intercourse behaviors for adolescents and emerging adults. This paper uses open-ended coded data from a longitudinal study of college students ( N = 346; Mean age = 18.5, 52% female, 27% Hispanic/Latino [HL], 25% non-HL European American, 23% non-HL Asian American, 16% non-HL African American, 9% non-HL Multiracial) to examine what emotional respons…
Patterns of Adolescent Sexual Behavior Predicting Young Adult Sexually Transmitted Infections
Long-Term Consequences of Early Sexual Initiation on Young Adult Health
Although early sexual initiation has been linked to negative outcomes, it is unknown whether these effects are causal. In this study, we use propensity score methods to estimate the causal effect of early sexual initiation on young adult sexual risk behaviors and health outcomes using data from the National Longitudinal Study of Adolescent to Adult Health. We found that early sexual initiation predicted having 2 or more partners (for both males a…
Age-varying associations between nonmarital sexual behavior and depressive symptoms across adolescence and young adulthood
Research has demonstrated associations between adolescent sexual behavior and depressive symptoms, but no single study has examined individuals at different ages throughout adolescence and young adulthood in order to determine at what ages sexual behavior may be associated with higher or lower levels of depressive symptoms. Using nationally representative longitudinal data and an innovative method, the time-varying effect model (TVEM), which exam…
Latent Classes of Adolescent Sexual and Romantic Relationship Experiences
Adolescents' sexual and romantic relationship experiences are multidimensional but often studied as single constructs. Thus, it is not clear how different patterns of sexual and relationship experience may interact to differentially predict later outcomes. In this study we used latent class analysis to model patterns (latent classes) of adolescent sexual and romantic experiences, and then examined how these classes were associated with young adul…

Sexual Behaviors in Mexico
Adolescent sexuality research has expanded to include noncoital behaviors, but there is limited knowledge about individual factors such as cultural values associated with these sexual behaviors outside of industrialized nations. Thus, we examined associations between Latino values (familism, sexual guilt, and importance of female virginity) and three sexual behaviors (making out, oral sex, and vaginal sex), among adolescents ages 12-19 (53% femal…

Oral vs. Vaginal Sex Experiences and Consequences Among First-Year College Students
Gender, Contraceptive Attitudes, and Condom Use in Adolescent Romantic Relationships
Although sexual risk behavior occurs in a dyadic context, most studies of adolescent sexual behavior focus on individuals. This study uses couple data ( N = 488 couples) from the National Longitudinal Study of Adolescent Health to examine how partners' contraceptive attitudes correlate over time and whether male or female partners' attitudes are better predictors of condom use. Net of their own prior attitudes, partners' prior attitudes predicted…

Changes in religiosity after first intercourse in the transition to adulthood
Religiosity delays initiation of sexual behavior, but the association may be bidirectional, and individuals may become less religious after first intercourse. This study uses longitudinal data from college students to examine whether two aspects of religiosity change before and after first intercourse using multiphase growth curve models. Students' religiosity did not change in the six months preceding first intercourse, but on average they atten…

Positive and negative perceived consequences of first intercourse among middle and high school students in Puebla, Mexico
Relatively little is known about young people's interpretations of sexual behaviour in Latin America. In this study, we examine the most commonly perceived consequences of first sexual intercourse among Mexican middle and high school students, how perceived consequences differ by gender, and factors that may predict experiencing more positive or negative consequences. Sexually active Mexican students aged 12-19 years (n = 268) reported whether th…
