An investigation was conducted to determine whether the Parental Attitude and Behavior Inventory (PABI) Form III, a lengthy self-report instrument (577 items each for both parents) for assessing parents' attitudes and behavior toward their children and each other, could be shortened to a more feasible length. This terminal report summarizes the results of the statistical evaluation of the final scoring system for the PABI. The reliability and validity of the revised system has been demonstrated to be comparable to the original system. In addition, the cross-validity of the revised system is noted to be within acceptable limits of shrinkage. Acquiescence contributions are available for various subgroups, and, normative tables have been established. (AG)
