Abstract: Measurement of attitudes before and after an educational intervention generally reflects both the impact of the session and the fact that the best predictor of attitudes after the session are attitudes before the session. Statistics currently available provide contradictory information; both measures of association and measures of difference are statistically significant. Current tests of the significance of change either have restrictive assumptions or do not take into account people who do not change. A new measure is proposed which incorporates information on amount and direction of change. Delta is calculated from a contingency table of the pre-and postmeasurements. It ranges from + 1, signifying that everyone changed in one direction to -1, that is, everyone changed in the opposite direction, and becomes 0 when there is perfect correlation in scores or equal change in both directions. Delta is useful in assessing which attitudes have been most influenced by the educational intervention.
