Suicide-nearness assessed with PORT, the Percept-genetic Object-Relation Test: A replication and a reliability study.

Area of Science:

• Psychology
• Psychiatry
• Perceptual Psychology

Background:

• The Percept-genetic Object-Relation Test (PORT) has identified potential indicators of suicidal ideation.
• Assessing the reliability and validity of these indicators is crucial for clinical application.

Purpose of the Study:

• To determine the reliability and validity of the previously identified "suicide cluster" within the Percept-genetic Object-Relation Test (PORT).
• To investigate specific PORT signs, such as "lack of attachment relationships" and "Motor activity," in relation to suicide attempts.

Main Methods:

• The study involved 20 individuals who had attempted suicide and 70 controls.
• Inter-rater reliability for scoring PORT was assessed, showing high correspondence (95%-100%).
• Statistical analysis was used to compare PORT scores between attempters and controls.

Main Results:

• High inter-judge reliability (95%-100%) supports the consistency of PORT scoring.
• "Lack of attachment relationships" and "Motor activity" emerged as significant indicators within the PORT suicide cluster.
• Significant differences were observed in PORT scores between suicide attempters and controls.

Conclusions:

• The Percept-genetic Object-Relation Test (PORT) demonstrates reliability and validity in identifying a "suicide cluster."
• Specific PORT signs, including "lack of attachment relationships" and "Motor activity," are significant indicators associated with suicide attempts.
• The findings contribute to understanding the role of psychiatric disorder in suicide assessment using perceptual tests.
