چکیده:
Objective: Suicide is a major public health problem with little information about the role of
personality characteristics of people who chemically commit suicide. The present study aimed
to investigate the role of personality traits in the chemical suicide attempters.
Methods: In a case-control study, 100 patients with attempted suicide selected by convenience
sampling were compared to 100 normal subjects as a control group selected by consecutive
sampling in terms of personality traits using short form 5-factor questionnaire of NEO.
Results: Suicide attempters got significantly higher scores in neuroticism and also lower
scores in extroversion, openness, agreeableness, and conscientiousness (P<0.01) compared to
normal individuals. Interaction effects of group membership by sex revealed that male suicide
attempters had always higher neuroticism levels and lower extraversion and openness (P<0.05)
compared to the other sex group.
Conclusion: The findings accurately identified the basic personality dimensions influencing
the antisocial phenomenon and provided approaches for prevention and treatment of suicide
attempters.

"Methods: In a case-control study, 100 patients with attempted suicide selected by convenience sampling were compared to 100 normal subjects as a control group selected by consecutive sampling in terms of personality traits using short form 5-factor questionnaire of NEO.
Overall, studies in the field of per- sonality characteristics influencing on suicidal thoughts or its attempts, showed that factors such as neuroti- cism, extraversion, novelty seeking, low levels of harm avoidance hold the most promises in relation to suicide thoughts or suicidal behaviors (Brezo, Paris, & Turecki, 2006; Calati et al.
Ultimately, the multivariate analysis of covariance (MANCOVA) was implemented to study the effects of the main and the interactive effects of the groups (normal and suicidal) and gender (male and female) on personal- ity traits upon controlling the confounding variables.
Thus, the mean values in Table 2 show that unlike the women in the suicide group and the normal persons, the men with attempted suicide emotional and avoidance methods rather than problem solving ones to cope with stress, and they are basically weak in dealing with stressful situations (Leventhal & Brooks-Gunn, 2004).
The results obtained in this study regarding the interac- tive effect of group membership and sex on personality trends showed that there was a difference in this regard in the following personality traits: neuroticism, extrover- sion, and openness (Table 2), so that neurotic men in the suicide group obtained higher N scores.
The results obtained in the present study regarding lower extroversion scores obtained by men in the suicide group are in good agreement with other research (Lev- enthal & Brooks-Gunn, 2004; Chapman et al."
