Patients with schizophrenia who have attempted suicide exhibit different temperament and character traits compared to their non-suicidal counterparts, according to Turkish researchers.
“Our data indicate that schizophrenic patients will show a greater risk for suicide according to certain personality configurations,” said Okan Ekinci, M.D., of Yozgat State Hospital and team.
The study included 94 stable patients with schizophrenia who were between the ages of 18 and 65 years. Of these, 46 had a lifetime history of suicide attempts.
The participants were evaluated with the Temperament and Character Inventory (TCI). The scores of suicide attempters were compared with scores of non-attempters.
The results showed that suicide attempters had significantly higher TCI temperament scores for harm avoidance and persistence compared with non-attempters.
Regarding character traits, suicide attempters had significantly lower TCI scores for self-directedness and cooperativeness compared with non-attempters.
Harm avoidance, persistence, self-directedness, and cooperativeness were strong predictors for lifetime suicidal attempts among the patients.
Writing in Comprehensive Psychiatry, Eking and team “found evidence in support of personality factors as predictors of suicide” in schizophrenia patients.
“Clinicians should be aware of this issue and take it into consideration when assessing and treating patients with schizophrenia because suicide is one important cause of mortality in this patient group,” wrote the authors.
