Types of attempted suicide (parasuicide).

The clinical usefulness of a typology of parasuicide, reported in a previous paper, has been improved. A finer grained classification, using six instead of only three clusters, has proved itself to be clinically highly realistic. By a new method of cluster analysis which examines 80 attributes in each of 350 patients, the following types of parasuicide emerge: (1) operant, not alienated; (2) repeaters; (3) depressed with high life endangerment; (4) operant and alienated; (5) wristcutters; (6) undifferentiated. This more detailed typology may offer some advantages for clinical management and research.
