The Use Of Analysis Of Covariance Structures To Assess Beta And Gamma Change.

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.
