Some determinants of worker performance: bus drivers in the Scottish Bus Group

This thesis reports the results of a major survey into the determinants of bus driver performance. Over 600 drivers in the Scottish Bus Group were given a battery of three psychological tests: (i) the Ingleton Word Recognition Test, (ii) the IPAT Culture Fair test of "g" and (iii) the Cattell 16PF. Scores on these were factor analysed along with age to give six second-order factors. Over forty measures of work performance were also collected for each driver; these were factor analysed and six factors emerged. Factor scores from the two analyses were correlated and the main dimensions of personality and performance determined. The thesis also presents a review of the history and structure of the British bus industry, and of the role and duties of the bus driver. Methodological issues in the research also receive detailed discussion. The results have already started to be applied in the selection of new drivers by the Scottish Bus Group
