Dependent: variable: history of suicide attempt (yes/no).

a. Independent variables: sex, age, mature defense style, neurotic defense style, immature defense style.

Model 1: Nagelkerke R² = 0.229 (p < 0.05).

b. Independent variables: sex, age, all defense mechanisms.

Model 1: Nagelkerke R² = 0.143 (p < 0.05).

Model 2: Nagelkerke R² = 0.216 (p < 0.05).

SE, standard error; OR, odds ratio; CI, confidence interval.

Values of p < 0.05 were accepted as significant and marked in bold.
