Certain studies associate those who experience suicidal ideation with family disruption. Relationships with parents and friends
According to a study conducted by Ruth X. Liu of San Diego State University, a significant connection was found between the parent–child relationships of adolescents in early, middle and late adolescence and their likelihood of suicidal ideation. The study consisted of measuring relationships between mothers and daughters, fathers and sons, mothers and sons, and fathers and daughters. The relationships between fathers and sons during early and middle adolescence show an inverse relationship to suicidal ideation. Closeness with the father in late adolescence is "significantly related to suicidal ideation". Liu goes on to explain the relationship found between closeness with the opposite sex parent and the childs risk of suicidal thoughts. It was found that boys are better protected from suicidal ideation if they are close to their mothers through early and late adolescence; whereas girls are better protected by having a close relationship with their father during middle adolescence. An article published in 2010 by Zappulla and Pace found that suicidal ideation in adolescent boys is exacerbated by detachment from the parents when depression is already present in the child. Lifetime prevalence estimates of suicidal ideation among nonclinical populations of adolescents generally range from 60% to 75% and in many cases its severity increases the risk of suicide.
