Background:

Suicidal behavior is a significant public health concern.
Understanding long-term determinants of suicidal behavior in depressed individuals is crucial for effective prevention and treatment.

Purpose of the Study:

To identify predictors of suicidal behavior over an 18-year period in a cohort of depressed patients.
To explore the differential determinants for various aspects of suicidal behavior, including presence, frequency, intent, and medical threat.

Main Methods:

Longitudinal study of 89 depressed in-patients.
Inclusion of clinical features, personality traits, and history of loss as potential predictors.
Application of generalized linear modeling to analyze relationships between variables and suicidal behavior outcomes.

Main Results:

Severe dysphoria, a history of alcoholism, and chronic physical illness were significant predictors of suicidal attempts.
Distinct variables were found to predict the frequency, intent, and medical severity of subsequent suicidal attempts.

Conclusions:

The determinants of suicidal behavior are multifaceted and vary depending on the specific aspect of the behavior being considered.
This research highlights the need for individualized assessment and intervention strategies targeting different facets of suicidal behavior in depressed patients.
