Objective: The aim of this study was to determine the validity of assigning suicidal individuals into differing typologies of suicidality based on their reported wish to live and wish to die. %26lt;br%26gt;Methods: One hundred five inpatients who reported suicidal ideation in the previous 48 hours completed a battery of assessments during inpatient psychiatric hospitalization. An algorithm was used to assign participants into 1 of 3 typologies of suicide: wish to live, ambivalent, or wish to die. Discriminant function analysis and group classification were used to predict group membership, followed by multiple analysis of variance and follow-up contrasts to measure between-group differences. %26lt;br%26gt;Main Results: Group classification resulted in 76% accuracy for predicting typology of suicidality based on scores from suicide-specific measures. Self-perceived risk of suicide and hopelessness were the strongest variables at differentiating between the 3 groups. Patients in the wish to die typology were less likely to report having never made a suicide attempt. %26lt;br%26gt;Conclusions: Creating typologies of suicidality may prove useful to clinicians seeking to better differentiate among suicidal patients within a limited period of assessment.
