The purpose of this study is to examine the effects of cohabitation on children in kindergarten and how this varies by race. Many researchers have shown that children being raised in cohabiting families do not perform as well as children being raised in married parent families (Manning and Seltzer 2009; Artis 2007; Raley et al 2005). Furthermore, demographic trends show that cohabitation among Latinos is very similar to marriage, whereas among whites they are two very different things (Choi and Seltzer 2009). My research combines these two ideas to investigate how cohabitation may affect Latino children differently than it affects white children in terms of internalizing and externalizing behavior problems. I hypothesize that though whites will be negatively affected by cohabitation, Latinos will not have this negative effect. Evidence supports hypotheses and suggests that, indeed, Latino children are not as negatively affected by cohabitation as Whites.

Children and Adolescents with emotional and behavioral disabilities (EBD) are often involved in aggression, acting out, bullying, violence, substance abuse, and juvenile crime. However, the limited Korean studies have focused primarily on bullying of students with developmental disabilities or intellectual disabilities. Therefore, the current study aimed to explore contributing factors to traditional bullying and cyberbullying in Korean children and adolescents with EBD. The current study surveyed 112 students with EBD between ages of 10 and 15 and their parents (guardians). The results revealed that internalizing problem behaviors including anxious/depression, withdrawal/depression, and somatic problems significantly affected traditional bullying victimization of Korean students with EBD. The peer support was a significant factor affecting cyberbullying victimization. Furthermore, the maternal psychological control was a meaningful factor affecting perpetration at school and in cyber world. Based on the findings, the present study described implications regarding prevention and intervention programs for addressing traditional bullying and cyberbullying victimization and perpetration.
