The development of two instruments useful in evaluating supervisory behavior is described in this paper. Form 1 of the Supervisory Behavior Description Questionnaire (SBDQ) is an ordinal-type scale originally composed of eight sub-scales and 132 triads of items. Each item is composed of a very directive statement, a collaborative statement, and a very non-directive statement. Form 1 of the instrument was field tested on 107 graduate students who also completed the California F scale measuring authoritarianism. The results were correlated with their SBDQ responses. A step-wise multiple regression formula was used to analyze the data. The results indicated that most respondents preferred the directive mode of supervision. However, a significant majority preferred the non-directive mode of supervision of some behaviors. Few respondents indicated a preference for the collaborative mode of supervisory behavior. Form 2 of the SBDQ is a modified semantic differential instrument originally consisting of the statements contained in Form 1. Form 2 was administered to 60 graduate students along with the Tennessee Self Concept Scale. Some of the findings are summarized in the text. (Author/MLF)
