Abstract
This study set out to develop a new Type A Behavioural Pattern Measure for the Organisational Context (OTABPM) because of the psychometric limitations and noncontextualisation of currently available Type-A Behaviour Pattern measures. To develop this measure, I started by writing 180 items for three dimensions of Type A, those being Achievement Striving, Hostility, and Time Urgency. These items were sent to 12 experts to review, which led to 96 items. Responses to these 96 items were obtained from 239 participants located primarily in the United States and South Africa. Classical Test Theory and Item Response Theory (the Graded Response Model) was used to analyse the data. The results showed that the items mostly had satisfactory psychometric properties and that the scale scores had good reliability. Some items were found to be problematic and were labelled as potential candidates for removal in future studies. These results hold promise for the revival of Type A research in organisations because the OTABPM appears to has satisfactory psychometric properties. Future research should investigate the item functioning of the measure on different samples in order to replicate the results obtained in this study and better understand which items should be removed. Further implications for research and practice are presented.
