Abstract:

Objectives: To explore the association between personality dimensions and suicidal behavior, and its recurrence

Methods: A number of n = 474 subjects referred for a psychiatric consult were assessed with structured interviews for mood and personality disorders (SCID I and II), history of suicidal behavior and suicide ideation, as well as other questionnaires for depression, anxiety and coping.

Results: Eleven dimensions analogous to their personality disorder categories were extracted through Principal Component Analysis with Monte Carlo replication validation. A logistic regression using their regression scores as predictors evidenced that the compulsive factor increased the odds for suicide attempt (OR = 1.3, CI95%: 1.02 – 1.64, p = .036). Borderline traits had the strongest association with relapse of attempted suicide (OR = 4.23, CI95%: 1.44 – 12.46, p = .009. Avoidant (OR = 2.74, CI95%: 1.05 – 7.19, p = .041) and histrionic traits (OR = 1.92, CI95%: 1.13 – 3.23, p = .014) also increased significantly the odds for repeated suicide attempts. In contrast, dependent (OR = .5, CI95%: .26 - .93, p = .029), narcissistic (OR = .37, CI95%: .15 - .86, p = .022) and sociopath (OR = .22 CI95% = .08 - .59, p = .003) factors were least likely to be associated with multiple suicide attempts.

Conclusions: Personality dimensions are useful predictors for suicidality beyond the diagnosis of personality disorder.

Rezumat:

Obiective: Explorarea asocierii dintre dimensiuni ale personalitatii la adult si comportamentul suicidar, precum si recurenta acestuia

Metoda: Un esantion de n = 474 subiecti trimisi pentru consult psihiatric de specialitate de medicul lor de familie au fost evaluati prin interviu structurat pentru tulburari affective si de personalitate (SCID I si II), istoric de comportament suicidar si idei de suicid, precum si alte chestionare pentru depresie, anxietate si strategii de coping

Rezultate: Unsprezece dimensiuni de personalitate analoge tulburarilor descries pe axa II au fost extrase folosind PCA (Analiza de Componente Principale) cu validare prin replicare Monte Carlo. Folosind scorurile de regresie ale acestora intr-un model de regresie logistica compulsivitatea a reiesit ca principal predictor pentru tentativa de suicid (OR = 1.3, CI95% 1.02 – 1.64, p = 0.036). Trasaturile de personalitate borderline, mai mult, au fost cele associate cu recaderi in comportament suicidar (OR = 4.23, CI95%: 1.44 – 12.46, p = 0.009). Dimensiunile evitanta (OR = 2.74, CI95%: 1.05 – 7.19, p = 0.04) si histrionica (OR = 1.92, CI95%: 1.13 – 3.23, p = 0.014) au contribuit de asemenea la model, crescand sansele (odds) pentru o noua tentativa de suicid. In contrast, dimensiunile dependent (OR = 0.5, CI95%: 0.26 – 0.93, p = 0.029) narcissist (OR = 0.37, CI95%: 0.15 – 0.86, p = 0.022) si sociopat (OR = 0.22, CI95%: 0.08 – 0.59, p = 0.003) au fost associate cu o scadere a sanselor de tentative repetate de suicid.
