title: Suicide-nearness assessed with PORT, the Percept-genetic Object-Relation Test: A replication and a reliability study.
abstract: To determine the reliability and validity of a previously identified "suicide cluster" in the Percept-genetic Object-Relation Test (PORT), which test documents subliminal perception of object-relation pictures, 20 suicide attempters and 70 controls were investigated. The correspondence between scores assigned by two judges was 95%-100%. The suicide-cluster signs in PORT, notably "lack of attachment relationships" and "Motor activity," were significant. Differences between the results of this and the previous study are discussed as is the role of psychiatric disorder in suicide.
