This article discusses the process by which a questionnaire was developed specifically to measure attitude to shared learning. Over a three-year period the attitude questionnaire was developed and tested using pre-registration students who were engaged in a shared learning programme. These pre-registration students were from three professional groups, namely occupational therapy (OT), diagnostic radiography (DR), and therapeutic radiography (TR). While the study hypothesis was that shared learning would improve attitudes over the three-year period, the focus of this article is to discuss the process by which the research instrument was developed. The rationale for focusing on the process is a simple one. After a diligent literature search it was clear that there were no attitude questionnaires specific to attitude measurement in relation to shared learning. Thus without an already validated attitude to a shared learning questionnaire, it became imperative to create systematically a credible attitude measure of shared learning. The process centred on understanding how monadic scales are constructed and used to measure attitudes and perceptions of participants. Amongst a number of processes to be followed was the need also to check the reliability of the developed questionnaire. This was done using the Cronbach alpha coefficient. A Cronbach alpha coefficient of 0.7 was set as a minimum reliability requirement, which was duly satisfied. The outcome of this process was that it very useful to learn how to produce a suitable instrument to measure attitude to shared learning and to add in a small way to the range of attitude questionnaires available.
