Predicting Job Performance for the Visually Impaired: Validity of the Fine Finger Dexterity Work Task.
Giesen, J. Martin; And Others
The study was designed to determine the reliability and criterion validity of a psychomotor performance test (the Fine Finger Dexterity Work Task Unit) with 40 partially or totally blind adults. Reliability was established by using the test-retest method. A supervisory rating was developed and the reliability established by using the split-half method. The correlation between the supervisor's two separate scores based on their responses to odd and even items revealed a Pearson product-moment coefficient of .98. A factor analysis was computed to determine whether a general or distinct factor of performance existed. Two factors emerged: performance and compliance/conformity, of which performance was the stronger. A concurrent approach was used to establish the criterion validity of the Fine Finger Dexterity Work Task Unit. Statistical analysis revealed some degree of positive correlation between the predictor and criterion. It was concluded that the validity coefficient of .33 would be useful in selection when the selection ratio and base rate were favorable. (Author/CL)
