Is harassment based on personal characteristics such as race/ethnicity, sexual orientation, religion, or disability more detrimental than general harassment? In 2 large population-based studies of adolescents, more than one third of those harassed reported bias-based school harassment. Both studies show that bias-based harassment is more strongly associated with compromised health than general harassment. Research on harassment among youths rarely examines the underlying cause. Attention to bias or prejudice in harassment and bullying should be incorporated into programs and policies for young people.

Few studies have examined school‐based factors associated with variability in the victimization and health of lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth. Among 15,965 students in 45 Wisconsin schools, we identified differences based on Gay–Straight Alliance (GSA) presence. Youth in schools with GSAs reported less truancy, smoking, drinking, suicide attempts, and sex with casual partners than those in schools without GSAs, with this difference being more sizable for LGBTQ than heterosexual youth. GSA‐based differences were greatest for sexual minority girls on reported sex while using drugs. GSA effects were nonsignificant for general or homophobic victimization, grades, and school belonging. Findings suggest that GSAs could contribute to attenuating a range of health risks, particularly for LGBTQ youth.

In this study predictors of serious suicide attempts among lesbian, gay, and bisexual (LGB) youth were examined. Three groups were compared: youth who reported no attempts, youth who reported attempts unrelated to their sexual orientation, and youth whose attempts were considered related to their sexual orientation. About one third of respondents reported at least one suicide attempt; however, only half of the attempts were judged serious based on potential lethality. About half of all attempts were related to youths' sexual orientation. Factors that differentiated youth reporting suicide attempts and those not reporting attempts were greater childhood parental psychological abuse and more childhood gender-atypical behavior. Gay-related suicide attempts were associated with identifiability as LGB, especially by parents. Early openness about sexual orientation, being considered gender atypical in childhood by parents, and parental efforts to discourage gender atypical behavior were associated with gay-related suicide attempts, especially for males. Assessment of past parental psychological abuse, parental reactions to childhood gender atypical behavior, youths' openness about sexual orientation with family members, and lifetime gay-related verbal abuse can assist in the prediction of suicide attempts in this population.

Individuals change over time, often in complex ways. Generally, studies of change over time have combined individuals into groups for analysis, which is inappropriate in most, if not all, studies of development. The authors explain how to identify appropriate levels of analysis (individual vs. group) and demonstrate how to estimate changes in developmental processes over time using a multivariate nonstationary time series model. They apply this model to describe the changing relationships between a biological son and father and a stepson and stepfather at the individual level. The authors also explain how to use an extended Kalman filter with iteration and smoothing estimator to capture how dynamics change over time. Finally, they suggest further applications of the multivariate nonstationary time series model and detail the next steps in the development of statistical models used to analyze individual-level data.
