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.
There are a number of treatment options for people who experience suicidal ideation. Definitions
The ICD-11 describes suicidal ideation as "thoughts, ideas, or ruminations about the possibility of ending ones life, ranging from thinking that one would be better off dead to formulation of elaborate plans".The DSM-5 defines it as "thoughts  about  self-harm, with deliberate consideration or planning of possible techniques of causing ones own death".The Centers for Disease Control and Prevention defines suicidal ideation "as thinking about, considering, or planning suicide". Terminology
Another term for suicidal ideation is suicidal thoughts.When someone who has not shown a history of suicidal ideation experiences a sudden and pronounced thought of performing an act which would necessarily lead to their own death, psychologists call this an intrusive thought. A commonly experienced example of this is the high place phenomenon, also referred to as the call of the void.Euphemisms related to mortal contemplation include internal struggle, voluntary death, and eating ones gun. Risk factors
The risk factors for suicidal ideation can be divided into three categories: psychiatric disorders, life events, and family history. Psychiatric disorders
Suicidal ideation is a symptom for many mental disorders and can occur in response to adverse life events without the presence of a mental disorder.There are several psychiatric disorders that appear to be comorbid with suicidal ideation or considerably increase the risk of suicidal ideation. For example, many individuals with borderline personality disorder exhibit recurrent suicidal behavior and suicidal thoughts.
