In the 1950s Leary developed the model of an interpersonal diagnosis of personality. The author stated that communication can be described along two dimensions: the dominance - submission dimension and the cooperation - opposition dimension. On the basis of this model, Leary, Wubbels, Creton and Hooymayers developed a map to model interpersonal teacher behaviour. This model is adapted to the classroom by dividing Leary's original two dimensions into the eight behaviour types: leadership, helpful/friendly, understanding, student, responsibility/freedom, uncertain, dissatisfied, admonishing and strict. The model has been used in The Netherlands in the development of an instrument; The Questionnaire on Teacher Interaction (QTI), to gather students' and teachers' perceptions of interpersonal teacher behaviour. There are many versions of The Questionnaire on Teacher Interaction (QTI), but in this paper the Australian version of the QTI, which is more economical, is described. This version consists of 48 items which are descriptions of teachers' interpersonal behaviour. An example from the leadership scale is: This teacher talks enthusiastically about his/her subject and an example from the admonishing scale is This teacher gets angry unexpectedly. The QTI has a five-point response scale, ranging from Never/Not at all, to Always/Very.
