This paper reports to attempt to replicate in Britain Britton and Tesser's (1991) study of the relationship between scores on a time management scale and college grades using a larger sample size and a British (rather than American) student population. Subjects were 302 psychology students who completed the 18-item scale after their first term of study. Results were compared with data on an end-of-year examination, coursework grades awarded during the year, and the final end-of-year grade. Results indicated that the three-component structure of the scale used by Britton and Tesser was not sustained, and a revised two-component scale measuring "daily planning" and "confidence in long term planning" was preferred. The results from the Confidence in Long Term Planning sub-scale showed small but significant relationships with scores on coursework, examination results, and end of year assessments. In addition, women students scored significantly higher than men on the Daily Planning sub-scale. (DB)
