The Measurement of Non-Directive Supervisory Behavior in Education: A Factor-Analytic Validity Study.
Sirois, Herman A.
Using the constructs of Rogers, Ellis, and Barrett-Lennard, a twenty-five item Likert-type instrument, the Non-Directive Supervisory Behavior Scale, was developed to measure directive vs. non-directive supervisory behavior. One hundred ninety-five in-service teachers, randomly selected from two school districts, completed the twenty-five item questionnaire describing the behavior of their supervisors during supervisory conferences. The data were subjected to factor analysis and subsequent alpha-internal reliability estimates. Results indicated that the instrument is a one-factor or one-scale measure of supervisor non-directive behavior, with eleven of the questionnaire's twenty-five items comprising the scale. Alpha-internal reliability was estimated at .83. An estimate of the construct validity was based on the correlation between this scale and the pre-established Barrett-Lennard Relationships Inventory; both were administered concurrently to twenty-three teachers. Correlation was .67, corrected for attenuation at .80. The scale and supporting data are attached. (Author/CP)
