The reliability of group administration of the Bender-gestalt test

A. Problem and Hypotheses The present study attempts to ascertain the reliability of group administration of the Bender-Gestalt Test(BGT) using the koppitz Developmental Scoring System, in comparison to the usual method of individual administration. The hypotheses of this study are as follows : 1. No significant correlation coefficient will be observed between the BGT scores of Ss in Group Ⅰ who received an individual administration procedure on two occasions. 2. No significant correlation coefficient will be observed between the BGT scores of Ss in Group Ⅳ who received the group administration procedure on two occasions. 3. No significant correlation coefficient will be observed between the BGT scores of Ss in Group Ⅱ who received the individual administration Procedure first and the group administration procedure second. 4. No significant correlation coefficient will be observed between the BGT scores of Ss in Group Ⅲ who received the group administration procedure first and the individual administration procedure second. 5. No significant difference will be observed between mean BGT scores of Ss in Group Ⅱ who received the individual administration procedure first and mean BGT scores of Ss in Group Ⅲ who received the individual administration procedure second. 6. There will be no significant difference between the correlation coefficient between scores of Ss in Group Ⅰ who received the BGT individual administration procedure on two occasions and the correlation coefficient between scores of Ss in Group Ⅳ who received the BGT group administration procedure on two occasions. B. Method 1. Subjects The subjects consisted of 128 enrolled in the J elementary school in Daejeon city, Chungnam. The sampling method used was stratified random sampling. The subjects were assigned to one of four groups with each group stratified on the variables of age and sex. There were 32 Ss per group, yielding 128 Ss in the sample, ages 6 years, 12 months through 10 years, 11 months. 2. Instrument The BGT consisted of nine designs was used in this study (see figure 1) 3. Procedures Procedures for individual administration of the BGT were followed as suggested by Koppitz(1964). And the group administration procedure consisted of presenting 55.5×52.0㎝ BGT designs to groups of not more than 16 Ss. All Ss were from 6˚ to 15˚ from the designs. All protocols were scored using the Koppitz Developmental Scoring System. 4. Statistical Methods All data were analyzed statistical techniques as described by Ferguson(1966). The methods were as follows : Product-moment correlation, t-test, one-way ANOVA. C. Findings The main findings obtained were as follows: 1. There was no significant difference in the mean scores of Ss on individually administered and group administered BGT. 2. There was a significant correlation between pre- and posttest BGT scores of Ss receiving individual administration. 3. There was a significant correlation between pre- and posttest BGT scores of Ss receiving group administration. 4. Scores earned on the individual administration of the BGT following a prior exposure to the group administration procedure were comparable to scores earned on an individual administration of the BGT by Ss who had not had any prior exposure to the test. That is, there was no significant testing effect. 5. There was no significant difference between the reliability coefficients of the individually administered BGT and the group administered BGT. In sum, group administered BGT was as reliable as individually administered one, and there was no significant testing effect of the group procedure on the individually administered method.
