Research suggests a link between friendships and suicidality among U.S. youth but this link has not been confirmed across ethnicities. This study examined the relationship between friendships and suicidality among Mexican-and European-American adolescents. Specifically, the role of friendship problems (i.e., social isolation, poor quality friendships) and problematic friends (i.e., friends who were disconnected from school, delinquent friends) was explored. Participants were 648 community youth. Friends' school disconnection was related to Mexican-American girls' suicidal ideation while friends' delinquency was associated with European-American youth suicidal behavior. Friendship factors were no longer associated with suicidality after controlling for suicidality correlates such as depression. These findings indicate that the relationship between friendships and suicidality varies by gender and ethnicity. They also suggest a dominant role of depression.Suicidal thoughts and behaviors are a major health problem for youth in the United States (U.S.). According to the national Youth Risk Behavior Surveillance (YRBS) survey, 15% of students ages 14 to 18 report having "seriously considered" suicide in the past year, and 7% report having engaged 1 in suicidal behaviors one or more times in the past year (Centers for Disease Control and Prevention [CDC], 2008). Most studies (CDC, 2008;Locke & Newcomb, 2005;Tortolero & Roberts, 2001; but see Roberts, Roberts, & Xing, 2007, for an exception) found rates of suicidal ideation and/or nonfatal suicidal behavior among Hispanic youth to be higher than among non-Hispanic youth. Within Hispanic youth, rates of suicidality are particularly high among adolescents of Mexican-American descent (Canino & Roberts, 2001).Rates of suicidal ideation and nonfatal suicidal behavior differ by sex, with girls reporting significantly more of both. According to the YRBS survey, 19% of girls ages 14-18 report having seriously considered suicide, compared to 10% of boys; 9% of girls report nonfatal suicidal behavior, compared to 5% of boys (CDC, 2008).

"Nonfatal suicidal behavior" is used to refer to suicidal acts in which a person survives. "Suicide" refers to death by suicidal behavior. Finally, the word "suicidality" is used to describe both suicidal thoughts and suicidal behaviors across lethality (see Canetto, 1997, for a review of suicide terminology).
