Abstract

The purpose of this study was to investigate the reliability of the Frostig Developmental Test of Visual Perception (FDTVP), the effects of the sex of examiner, the sex of examinee, and mode of administration. The FDTVP was administered by twenty examiners to 123 subjects stratified according to demography (rural or urban), sex (male or female), grade (I or II), and mode of administration (group or individual) in a test-retest design. Examiner sex/subject sex combinations were changed from one testing occasion to the other for each subject. Based on the results of a study of the inter-rater reliabilities, protocols were randomly assigned to four persons for scoring. -- Percentile rank distributions of the total sample verified that the mean scores obtained in this study were very high relative to the norms established by Frostig. -- The overall test-retest reliability of the FDTVP was lower than reported by Frostig. The test-retest reliability findings for the group administration were generally higher than those found for individual administrations. Grade II reliabilities were much lower than Grade I reliabilities. For Grade I, the group administration produced the higher reliabilities. -- The analysis of variance showed few differences for sex of subject, sex of examiner, and administration mode. In all cases, the raw scores for each subscale, and the sum of scaled scores were analyzed. The sex of subject was significant only for subscale I. For subscale IV, a significant two-way interaction was found for sex of subject and sex of examiner. For the same subscale a significant three way interaction was found for sex of subject, sex of examiner and administration mode. -- Findings suggest that Grade II reliabilities are too low to warrant any use of the test for diagnostic or remedial prescriptions. For Grade I children, the group setting is the indicated administration mode. In addition, all existing evidence on the validity of the FDTVP must be questioned because of the nature of the score distributions.
