A method for point and interval estimation of change in criterion validity of multiple-component measuring instruments as a result of revision is outlined. The procedure is developed within the framework of covariance structure modeling, which complements earlier methods for testing change in composite reliability due to addition or deletion of…

Explains that from a prediction standpoint the confluence model is not very efficient. Very modest increments in accuracy are associated with family configuration variables once chronological age is covaried. Suggests that the major postulates of the theory be tested directly, within individuals and with longitudinal data. (Author/AS)

Early screening programs to determine learning problems in preschool children are evaluated. A review of early identification literature indicates considerable difficulty in describing screening results and determining when a screening program accurately identifies those students believed to be "at risk."

Group process and rating techniques were used to create a scale for measuring severity and frequency of 24 problem behaviors in institutionalized mentally retarded persons. A substantial correlation was found between scores and staff-time allocations, indicating usefulness of the scale as a predictor of staffing requirements for behavior…
