Detection of alpha, beta, and gamma change in assessments of organizational intervention have been problematic because of lack of clear definition of beta and gamma change and/or methods to assess such change. The present paper applies an analysis of covariance structures to this problem using pre and post employment responses to a questionnaire assessing human needs. An analysis of data transformed in a manner consistent with theoretical definitions of beta change indicated the presence of such change and further supported the use of the procedure.
