A theoretical model of adolescent suicidal behavior was examined separ
ately for 192 male and 329 female (N = 521) students of a suburban jun
ior high school in the southwest. The model consisted of five construc
ts: the predictor variables of depression, hopelessness, self-esteem,
and substance use and the criterion variable, suicide risk. A theoreti
cal model consisting of five research hypotheses was proposed based on
the suicide literature and was examined by path analysis using a stru
ctural equations statistical package, SAS PROC CALIS (Version 6.10). R
esults revealed that all relationships were in the predicted direction
. The final model reasonably accounted for the data in spite of some g
ender differences. Males progressed from depression to substance use a
nd then to suicide risk, while females progressed directly from depres
sion to suicide risk. Depression was a stronger predictor of low self-
esteem for females than for males. While hopelessness was a viable pre
dictor of substance use for both males and females, it was not a viabl
e predictor of suicide risk.
