A Test of the Validity of a Model of the Prerequisites of Effective Organisational Consulting

In 1988, personality and effectiveness data were collected from a sample of 105 organisational development consultants. A model was developed of the relationship between OD consultants′ personality characteristics and their effectiveness as change agents. The present study provides validation for that model by studying the same personality characteristics in a sample with slightly differing demographics. The question was tested statistically by using the regression equation from the sample used in 1988 to predict the dependent variable (consultant effectiveness) in this study′s sample.
