The Development and Validation of the Student Opinion Inventory Factor Scales

Abstract

A description is given of the development of the Student Opinion Inventory (SOI), an instrument designed to measure attitudes of students in secondary schools toward several aspects of their schools. The purposes of this investigation were to determine the concurrent validity of the SOI factor scales and to examine the reproducibility of the reliability estimates found in pilot studies of the instrument. Responses to the SOI from 367 students indicated that 5 of the 6 factor scales of the SOI possessed some concurrent validity. Furthermore, the obtained reliabilities of the factor scales were relatively high for attitudinal measures and closely reproduced reliability estimates established by the final pilot study of the instrument.
