Abstract

Suicide is the second leading cause of death among 10- to 14-year-olds. Despite a need to identify risk factors for suicide among children, there is limited research on suicidal thoughts and behaviors (STBs) in childhood. The interpersonal psychological theory of suicide (IPTS) suggests that the desire for suicide emerges from perceived burdensomeness and thwarted belongingness and that the transition from suicide ideation (SI) to a suicide attempt (SA) results from an acquired capability for suicide. However, no research has examined whether the IPTS applies to suicidal thoughts and behaviors among children. The present research examined components of the IPTS in a sample of ethno-racially diverse children. Children (N = 39) presented with acute SI and/or SA at New York City hospitals or clinics as a part of two studies. Participants completed a semi-structured interview that inquired about their STBs. The interviews were recorded, transcribed, and coded inductively using thematic analysis. The results suggested that thwarted belongingness stemmed from loneliness, lack of reciprocal care, and perceived rejection. Perceived burdensomeness was characterized by feelings of being a liability, internalized criticism, and low self-esteem. Participants reported events – such as corporal punishment – consistent with acquiring the capability for suicide. Older children (11-12-year-olds) reported experiences of hopelessness, but younger children did not, suggesting developmental differences. These findings highlight the relevance of the IPTS to children and the important role caregivers play in buffering against childhood STBs.
