An Analysis of the Dimensionality of the Pupil Control Ideology Scale

The Pupil Control Ideology (PCI) scale is a unidimensional instrument which reportedly measures a respondent's pupil control orientation on a humanistic-custodial continuum. In a recent study examining the dimensionality of the PCI, Graham, Halpin, Harris, and Benson (1985) used exploratory and confirmatory factor analytic procedures to analyze the responses of 362 college students. Results of the analyses provided support for the contention that the PCI is unidimensional and that a reduced 10 item, one factor model provided the best description of the data. The present study replicated the Graham et al. (in press) investigation with a sample of practicing classroom teachers. The findings were congruent with the results obtained by Graham and his colleagues. Consequently, it was recommended that the PCI should be refined and that the 10 item, unidimensional scale should be used in future investigations.
