RESUMO
OBJECTIVES: The dimensional approach to psychopathology has been proposed to reliably evaluate suicidality. Potential gender modulation of psychopathological dimensions associated to suicide attempts was investigated. METHODS: 91 subjects who committed a near-lethal suicide (SA group) and 374 who did not (nSA group) were recruited in a Psychiatric Intensive Care Unit regardless of their categorical diagnosis. The Hamilton Depression Rating Scale (HAM-D), the Brief Psychiatric Rating Scale - Expanded version (BPRS-E) and the Scale for Rapid Dimensional Evaluation (SVARAD) were administered at the admission. A Factorial Multivariate ANOVA was conducted according to General Linear Model: Sex and Suicidality were input as fixed factors, HAM-D, BPRS-E and SVARAD scores as dependent variables. RESULTS: Men with SA (MSA) displayed significant lower scores in SVARAD Activation dimension compared to women with SA (FSA) (p=0.049), men without SA (MnSA) (p<0.001) and women without SA (FnSA) (p<0.001). Both SA groups displayed significant higher scores compared to nSA groups in regard of Depression item (BPRS-E) (p<0,001). The MSA group displayed significant lower scores in Psychomotor agitation (HAM-D) compared to FSA (p=0,044), MnSA (p<0,001) and FnSA (p<0,001). CONCLUSIONS: By means of multifactorial statistics sex resulted a moderator of the relation between activation/agitation and suicidality, despite categorical diagnosis.
