Establishing Internal Consistency Reliability of Measurement Data of a New Instrument, the Information Preference Questionnaire.
Campbell, Kathleen T.
The estimation of the internal consistency of a newly constructed instrument using Cronbach's coefficient alpha is demonstrated. This study sought to determine the relationship, if any, between an individual's cognitive style and the preference for certain kinds of information used in making decisions. Cognitive style was determined with the Myers Briggs Type Indicator (MBTI) and a self-report questionnaire, the Information Preference Questionnaire (IPQ) designed to measure information preference. The IPQ contains 12 scenarios of school-related decisions. The prototype IPQ was field tested with four educators in a study that provided evidence of construct validity. The MBTI and the IPQ were administered to 53 principals and 11 assistant principals from a large metropolitan public school system in the South. The internal consistency reliability of the IPQ's four scales and the test as a whole was determined through the application of coefficient alpha. The IPQ measure was internally consistent, with a reliability estimate of 0.91 and measurement of all 4 scales was reasonable. Six tables present study data, and an appendix lists the Statistical Package for the Social Sciences commands for the reliability estimates. (Contains 21 references.) (SLD)
