Results of a study designed to explore the construct validity of the Change Facilitator Style Questionnaire (CFSQ) as a measure of the aspect of a principal's leadership style that includes leader behavior and combinations of behavior influenced by such things as belief systems, and knowledge and attitudes about leadership. The sample consisted of all teachers in 94 schools in 6 districts in Louisiana. Usable data were received from 1,921 teachers from elementary schools and secondary schools during the spring of 1992. Factor analyses of the responses fail to confirm the six biploar subscales of the CFSQ or the three dimensions of the principal change facilitator style construct as previously described in the literature. The CFSQ appears to measure reliably a unidimensional construct of change facilitator style termed proactive/strategic leadership. As a unidimensional construct measure, the CFSQ demonstrates reasonable construct validity and high reliability. Implications for understanding planned organizational change in schools are discussed. Three tables present study data. (Contains 65 references.) (SLD)
