A Test Reliability Analysis of an Abbreviated Version of the Pupil Control Ideology Form.
Gaffney, Patrick V.
A reliability analysis was conducted of an abbreviated, 10-item version of the Pupil Control Ideology Form (PCI), using the Cronbach's alpha technique (L. J. Cronbach, 1951) and the computation of the standard error of measurement. The PCI measures a teacher's orientation toward pupil control. Subjects were 168 preservice teachers from one private and one public college and 86 inservice teachers attending one private and one public college in south Florida. Cronbach's alpha is a special statistical measure that provides an estimate of the internal consistency of a test. Coefficient alpha is interpreted like a split-half coefficient and estimates the average split-half correlation from all possible divisions of a test. The higher the score on Cronbach's alpha, the better the evidence that items on the instrument are measuring the same trait. Preservice teachers from the private college had a Cronbach's alpha of 0.61 while their inservice counterparts had a Cronbach's alpha of 0.70. Preservice teachers at the public college had a Cronbach's alpha of 0.74 and their inservice counterparts had a coefficient alpha of 0.70. Results suggest that the abbreviated PCI is not as reliable as the original, although results are considered to be of a satisfactory level of reliability. The abbreviated PCI also requires less time for administration. An appendix presents the abbreviated PCI. (Contains 64 references.) (SLD)
