Prediction of suicidal thoughts based on the five - factor personality traits with the mediatory of defense mechanisms

The aim of this study was to prediction suicidal thoughts based on the five-factor personality traits with the mediatory of defense mechanisms.

The research method was descriptive-correlational, and the statistical population of the study consisted of all citizens living in Karaj in the winter of 2018, among whom using two-step random and voluntary sampling 550 people were selected. The tools study included NEO Five-Factor Inventory ; Defense Style Questionnaire-40 Beck Scale for Suicide Ideation . For data analysis, structural equation modeling was used.

In the present study, the indirect path coefficient between neuroticism trait with suicidal thoughts was positive and significant( P=0.001). Also, the indirect path coefficient between conscientiousness trait with suicidal thoughts was negative and significant ( P=0.001).

Affects like shame and guilt feelings that arise from unconscious conflicts and self-blame in neuroticism personalities and the inability to delay the satisfaction of the person's wishes and impulses in those who lack a high level of conscientiousness can lead to relying on different defense mechanisms and avoid unpleasant internal emotions and engage in suicidal thoughts. It is suggested to authorities, clinicians, and therapists arrange general education that targets those types of defense mechanisms in target individuals who when violated, have suicidal thoughts.
