Risky sexual behaviors among adolescents can increase adverse outcomes including unplanned pregnancy or contraction or transmission of disease. Adolescents who engage in risky sexual activities are at increased risk for adverse health and social outcomes compared to those who do not engage. Despite declines in adolescent pregnancy and birth rates, the diagnosis of sexually transmitted infections (STIs) is steadily increasing among adolescents.

Previous research found adolescents with low self-worth often utilize delinquency as a method of "self-enhancing" as proposed by Kaplan, which suggests the effects of delinquency can be both enhancing and damaging to adolescents' later reports of self-worth. We tested Kaplan's self-enhancing thesis to determine the extent to which different levels of self-worth in early adolescents foretell long-term levels of self-worth associated with delinquency among adolescents placed at-risk. Data from a sample of 982 primarily Black American (95%) adolescents living in high-poverty neighborhoods were analyzed using global and behavioral self-worth measures collected annually between the ages of 12-17, with school delinquency as the self-enhancing mechanism.

This study investigated internalizing problems, externalizing problems, and polydrug use among African-American youth residing in high-poverty neighborhoods, and tested the potential protective effects of religiosity, parental monitoring, and neighborhood collective efficacy on life stress and behavioral health outcomes (N = 576; 307 females; Mage = 16 years, SD = 1.44 years). A cumulative risk index reflected the combined effects of past year exposure to stressful life events, racial discrimination, and exposure to violence along with poor neighborhood ecology.

Mental health correlates of intimate partner violence (IPV) victimization including negative physical and mental health outcomes are well documented. However, certain subgroups of African American women, such as those living in impoverished, urban communities, are underrepresented in most studies and may experience IPV at higher rates. Furthermore, the circumstances of this women including poverty makes them at risk to IPV and its consequences.

The current study assessed for bidirectional relationships among supportive parenting (knowledge), negative parenting (permissiveness), and deviance in a sample ( = 5,325) of poor, inner-city African American youth from the Mobile Youth Survey (MYS) over 4 years. Cross-lagged path analysis provided evidence of significant bidirectional paths among parenting processes (knowledge and permissiveness) and deviance over time. Follow-up multigroup tests provided only modest evidence of dissimilar relationships by sex and by developmental periods.

This study examined prospective mediating relations among mother-adolescent attachment security, self-worth, and risk behaviors, including substance use and violence, across ages 13-17 in a sample of 901 low-income African American adolescents. Path analyses revealed that self-worth was a significant mediator between attachment security and risk behaviors, such that earlier attachment security predicted self-worth 1 year later, which in turn, predicted substance use, weapon carrying, and fighting in the 3rd year. Implications for the role of the secure base concept within the context of urban poverty are discussed.

Comorbidity of internalizing and externalizing problems and its risk and protective factors have not been well incorporated into developmental research, especially among racial minority youth from high-poverty neighborhoods. The present study identified a latent comorbid factor as well as specific factors underlying internalizing and externalizing problems among 592 African American adolescents living in economically disadvantaged neighborhoods (291 male; M age = 15.9 years, SD = 1.

In countries such as the USA, a substantial percentage of teenage pregnancies are intentional, and desire for pregnancy increases risk. Black US Americans have been found to be less accepting of homosexuality than their non-Black peers, which may result in minority ethnic teenagers demonstrating heterosexual orientation through attempting pregnancy. Young, socioeconomically disadvantaged African Americans were surveyed longitudinally regarding attitudes about their sexuality, pregnancy intentions and other psychosocial factors.

This study investigates whether certain types of substances are differentially related to certain risky sexual behaviors (RSBs) within the same population and determines whether combination substance use (SU) has additive, redundant or antagonistic effects on RSBs. African-American youth aged 9-19 participated in a large, community-based survey assessing substance use and sexual behaviors. Multilevel modeling was used to predict the differential influence of alcohol, marijuana, and cocaine use on condom use measured in the past 90days and at last intercourse, sex while drunk/high, and number of sexual partners.

Background: Genetic and environmental factors influence substance use behaviors in youth. One of the known environmental risk factors is exposure to life stressors. The aim of this project is to study the interaction between NR3C1 and CRHBP, genes thought to be involved in stress pathways, exposure to stressful life events, and adolescent alcohol use/misuse.

Researchers have long observed that problem behaviors tend to cluster together, particularly among adolescents. Epidemiological studies have suggested that this covariation is due, in part, to common genetic influences, and a number of plausible candidates have emerged as targets for investigation. To date, however, genetic association studies of these behaviors have focused mostly on unidimensional models of individual phenotypes within European American samples.

The current study examined 14 waves of data derived from a large, community-based study of the sexual behavior of impoverished youth between 12 and 17 years of age residing in the Deep South. We used multilevel linear modeling to identify ecological predictors of intercourse frequency and number of sexual partners among gender-specific subsamples. Results indicated that predictors of adolescent sexual behavior differed by both type of sexual behavior and gender.

The current study examined psychosocial predictors of change in intercourse frequency and number of sexual partners among youth within a socio-ecological framework and assessed whether these determinants vary by stage of adolescent development. Longitudinal data were derived from a large, community study of adolescent risky behavior among predominantly high-risk, African American youth. Significant predictors of intercourse frequency for early adolescents included age, gender, self-worth, and familial factors; for older youth, age, gender, self-worth, curfews, and sense of community exerted significant effects.

Background: This study examined whether relocating from a high-poverty neighborhood to a lower poverty neighborhood as part of a federal housing relocation program (HOPE VI; Housing Opportunities for People Everywhere) had effects on adolescent mental and behavioral health compared to adolescents consistently living in lower poverty neighborhoods.

Methods: Sociodemographic, risk behavior, and neighborhood data were collected from 592 low-income, primarily African-American adolescents and their primary caregivers. Structured psychiatric interviews were conducted with adolescents.

There is limited literature on the relationship between sensation seeking and adolescent risk behaviors, particularly among African Americans. We tested the association between psychometrically-derived subscales of the Zuckerman Sensation Seeking Scale and the intercepts and slopes of individual growth curves of conduct problems, sexual risk taking, and substance use from ages 13 to 18 years by sex. Boys and girls had different associations between sensation seeking and baseline levels and growth of risk behaviors.

Although sleep problems are associated with negative outcomes among adolescents, studies have not focused on sleep disorder symptoms among adolescents living in impoverished neighborhoods and how sleep problems may be related to two factors common in those environments: hopelessness and exposure to violence. This study used data from the longitudinal Mobile Youth Survey (MYS; N = 11,838, 49% female, 93% African-American) to examine trajectories of sleep problems by age (10-18 years) among impoverished adolescents as a function of gender, feelings of hopelessness, and exposure to violence. The results indicate that sleep problems associated with traumatic stress decline with age, with four notable distinctions.

Purpose: African-American youth, particularly those from low-income backgrounds, evidence high rates of negative outcomes associated with three problem behaviors, conduct problems, risky sexual behavior, and substance use. This study used a contextually tailored version of problem behavior theory (PBT) to examine predictors of the simultaneous development of problem behaviors in this specific cultural group.

Methods: Sociocontextual and individual variables representing four PBT predictor categories, controls protection, support protection, models risk, and vulnerability risk, were examined as predictors of co-occurring problem behaviors among economically disadvantaged African-American adolescents (n = 949).
