Evaluation of an Evolutionary Model of Self-Preservation and Self-Destruction

Predictions generated from deCatanzaro’s model of self-preservation & self-destruction were tested among 175 university students using variables constructed from a 164-item questionnaire. Multiple regression showed that benefit to kin was the best predictor of both depression & hopelessness. Discriminant analysis showed that reproductive potential of kin significantly differentiated suicide attempters from nonattempters. Overall, results support & extend deCatanzaro’s model & empirical findings.
