This study investigated the extent to which adolescent social network positions are associated with the risk of lifetime daily smoking and nicotine dependence (ND), and whether these associations differ by gender. Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 6,267), this study estimated multinomial logistic…

Objective: To identify the young adults' perception of their weight and examine the associations between young adults' weight perception and physical activities. Participants: A total of 4,882 participants' responses were derived from the Add Health, Wave III. Method: Chi-square tests were used to examine the weight perception and multinomial…

Background: Despite a vast literature linking in-home firearm access to youth suicides, few studies have examined whether and how "gaining" access to household firearms shapes adolescents' development of suicidal ideation. Objective: This study examined whether gaining access to household firearms among U.S. adolescents is associated…

This study uses the National Longitudinal Study of Adolescent to Adult Health to examine the effect of childhood trauma experiences on college graduation rates. A longitudinal mediation path analysis with a binary logistic regression is performed using trauma as a mediator between race, gender, first-generation status and college completion. The…

The detection of differential item functioning (DIF) is important in psychological and behavioral sciences. Standard DIF detection methods perform an item-by-item test iteratively, often assuming that all items except the one under investigation are DIF-free. This article proposes a Bayesian adaptive Lasso method to detect DIF in graded response…

We use the method of situational decomposition in an attempt to identify the causal effect of alcohol intoxication on adolescent sexual intercourse and contraception use. This approach assumes that the relationship between frequency of alcohol intoxication and behavior "while sober" is entirely spurious. With this in mind, the…

Background: Understanding the relationship between the perceived body weight, body mass index (BMI), and weight management-related behaviors is critical to preventing obesity in young adults. Purpose: To explore the relationship between perceived body weight and weight management-related behaviors and to assess the mediating effects of BMI between…

Suicide is the second leading cause of death for people aged 10-34 years old. Limited research has documented extant heterogeneities in suicide across the life course and among diverse sociodemographic groups. There is also limited research on the influences of mental health utilization on suicidal trajectories across the life course. This study…

This article aims to show the influence of social capital on the academic achievement of American students. Using data from Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health), this study explored how one of the domains of social capital, the family, makes a difference to educational outcomes in higher…

This study shows that residual variation can cause problems related to scaling in exponential random graph models (ERGM). Residual variation is likely to exist when there are unmeasured variables in a model--even those uncorrelated with other predictors--or when the logistic form of the model is inappropriate. As a consequence, coefficients cannot…

Evidence suggests that youth progressively experience mental health needs and discover mental health symptoms for the first time in adolescence. Schools have come to the forefront of providing mental health services, as adolescents spend most of their day in the academic setting. The current study aimed to examine individual and school-level…

This study uses a subsample from the National Longitudinal Study of Adolescent to Adult Health to examine protective factors for lower-income, first-generation students. A logistic regression model is used to explore the impacts of (1) gender, (2) race, (3) perceived sense of belonging during middle or high school, and 4) protective adult…

We show that educational outcomes of sexual minorities are consistent with efforts to mediate future discrimination. Gay men and lesbians obtain more years of schooling than heterosexual men and women, between 0.6 and 1.2 years. This difference is robust to controlling for observable characteristics for men but not women. Gay men and lesbian women…

Research suggests a link between precocious transitions to adulthood (e.g., high school dropout) and maladaptation, and this association is typically assumed to be uniform. We propose that this monolithic portrayal of precocious transitions as problematic for adult functioning is unwarranted, particularly across identities defined by gender,…

Criminological literature has examined the potential for gendered pathways of offending, while also recognizing the gendered risk for victimization. General strain theory explicitly recognizes this gendered risk as strains that structure differences in these experiences for males and females. The current article tests the longitudinal risk for…
