Personality Dimension, Suicidal Intent, and Lethality: A Cross-sectional Study of Suicide Attempters with or Without Personality Disorders.

BACKGROUND

Although personality disorders (PD) are known risk factors for suicide attempts, studies on personality dimension are scarce, which may provide further insights for interventions.

METHODS

The relationship between personality dimension, lethality, intent, and quality of life (QOL) was studied in suicide attempters with or without PD. We used the international personality disorder examination (IPDE) dimensional score, the scale for assessment of lethality of suicide attempt (SALSA), suicide intent scale (SIS), and WHOQOL-BREF QOL scale, to assess a sample of suicide attempters admitted to a general hospital.

RESULTS

PD was present in 43.2% and 57.9% of them had more than one PD. Comparison of attempters with or without PD suggested that the lethality of attempts and QOL were comparable, whereas self-reported suicide intent was significantly low in patients with PD. A higher proportion of PD patients reported relational problems as the reason for the attempt. The personality dimensional score was significantly higher for female attempters from urban backgrounds than for those with previous attempt histories. It was negatively correlated with the lethality of attempts and suicide intent.

CONCLUSION

It is important to explore the personality dimension of the suicide attempters, along with PD, that may highlight additional risks and suggest the need for specific support.
