Friendship factors and suicidality: common and unique patterns in Mexican American and European American youth.

Research suggests a link between friendships and suicidality among U.S. youth, but this link has not been confirmed across ethnicities. The relationship between friendships and suicidality among Mexican American and European American adolescents was examined in this study. 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.

Friendships and suicidality among Mexican American adolescent girls and boys.

Friendship factors have been implicated in adolescent suicidality, but this relationship has not been verified across ethnicities. This study examined suicidality and friendship problems (i.e., social isolation, poor friendship quality, friends' school disconnection, and friends' delinquency) among Mexican American adolescents, an understudied, vulnerable group in terms of suicidality. Three hundred thirty-eight community adolescents, two-thirds of whom were educationally at-risk, participated in the study. Suicidal ideation and behavior rates were high, particularly among girls. Friends' school disconnectedness increased girls' odds for suicidal ideation by 13%. This association was even greater for girls in good academic standing. Friendship problems were not associated with suicidality in boys. Ethnic identity was a minor factor in suicidal ideation, and only for girls. These findings confirm, among Mexican American adolescents, the role of gender in the relationship between friendship and suicidality.
