The Bender-Gestalt test is a widely used tool for assessing visual-motor maturity and detecting neurological impairments.
Korsakoff's psychosis and paranoid schizophrenia are conditions that can affect cognitive and perceptual functions, potentially impacting performance on such tests.
Purpose of the Study:
To compare the validity of four different administration methods for the Bender-Gestalt test.
To investigate the potential of an enhanced method ('perfect method') to improve predictive validity.
Main Methods:
The Bender-Gestalt test was administered to 30 individuals with Korsakoff's psychosis, 30 with paranoid schizophrenia, and 30 healthy controls.
Four distinct administration methods were employed for each participant group.
Main Results:
All four Bender-Gestalt test administration methods demonstrated good concurrent validity across the participant groups.
The 'perfect method,' involving error correction and redrawing, showed promise in enhancing the test's predictive validity.
Conclusions:
The Bender-Gestalt test, across various administration methods, is a valid tool for differentiating between clinical groups and controls.
The 'perfect method' warrants further investigation for its potential to improve diagnostic and prognostic accuracy of the Bender-Gestalt test.
