Personality predictors of outcome for adolescents hospitalized for suicidal ideation.
OBJECTIVE
Recent cross-sectional studies of adolescents have noted an association between the personality traits of perfectionism and self-criticism and suicidal ideation. The present study was undertaken to examine the relationship between personality dimensions and the outcome of treatment of adolescents hospitalized for suicidal ideation or behavior.


METHODS
The study group was composed of 78 adolescents who were admitted to an adolescent psychiatric inpatient unit for suicidal ideation or attempts. Subjects completed measures of self-criticism, interpersonal dependency, self-oriented perfectionism, and socially prescribed perfectionism as well as the broad, higher-order trait neuroticism. Depression symptoms, hopelessness, and suicidal ideation were assessed at the beginning (time 1) and end (time 2) of their inpatient treatment. Readmissions were identified by review of medical records 1 year after hospital discharge.


RESULTS
After controlling for baseline symptoms, neuroticism was associated with posttreatment depression and suicidal ideation. After controlling for time 1 symptoms and neuroticism in multiple regression analyses, self-criticism was associated with post-treatment hopelessness and depression. Logistic regression analysis was used to identify predictors of readmission. Baseline suicidal ideation and neuroticism were predictive of psychiatric readmission within 1 year of discharge.


CONCLUSIONS
Neuroticism and self-criticism are potentially useful predictors of outcome in suicidal adolescents and can be assessed quickly and reliably. Therapeutic interventions directed at self-criticism (e.g., cognitive-behavioral therapy) may be useful in the treatment of suicidal adolescents.
