Concurrent validity of a stress-vulnerability model of suicidal ideation and behavior: a follow-up study.
A follow-up study to test the concurrent validity of a stress-vulnerability model of suicidal ideation and behavior was conducted. A total of 202 college students (139 females, 63 males) completed self-report measures of life stress, loneliness, depression, dysfunctional cognitions, reasons for living, hopelessness, current suicide ideation, and predictions of future suicide probability. The results of a multiple-regression analysis indicated that 30% of the variation in suicide ideation scores could be accounted for by the linear combination of negative life stress, depression, loneliness, and few reasons for living. The linear combination of current suicide ideation, hopelessness, dysfunctional cognitions, and few reasons for living explained 56% of the variance in self-predicted future suicide probability. The results are interpreted as being supportive of the proposed model.
