1. Objectifs

Intentions :
« In this paper, we provide additional evidence supporting the role of IABs [impulsive-aggressive behaviors] as intermediate phenotypes. We explored the relation between a history of suicide attempts, and family history of suicidal behavior, on a sample of psychiatric outpatients. » (p. 173)

Questions/Hypothèses :
« Our main hypothesis was that patients with a family loading of suicidal behavior would display higher scores of impulsive-aggressive behaviors measures, irrespective of their primary psychopathology, than patients with negative family history of suicidal behavior. » (p. 173)

2. Méthode

Échantillon/Matériau :
« The study sample consisted of 474 adults, recruited consecutively from a community mental-health clinic. » (p. 173)

Instruments :
Questionnaires

Type de traitement des données :
Analyse statistique

3. Résumé

« We took advantage of direct measures of impulsivity and aggressiveness, using standardized inventories, and also employed a robust statistical approach, that sought to control most frequent confounders. In synthesis, impulsive-aggressive behaviors are more than putative markers for a suicidal diathesis; they coexist with familial aggregation of suicidal behaviors and may provide the platform for a comprehensive understanding of why some individuals are predisposed to suicide. Further research is yet needed to go more in-depth and establish the state vs. trait component of such behavioral susceptibilities, including the integration of environmental factors such as trauma, and recent life events. » (p. 176)
