This study examined the effectiveness of a behavioral parent training package that included initial training in two settings in the home with generalization of parenting skills (and the need for additional intervention) being assessed to a third setting in the home. Training in behavior modification skills was introduced in a multi ple baseline design across parents. The results showed that although all parents increased their correct use of behavior modification skills following the introduction of intervention in two home settings, only one parent out of three spontaneously generalized these skills to a third home setting. The results of this study suggest that generalization of parenting skills across home settings may not take place for some parents without specific programming. Finally, the study showed that once skills had generalized across settings, parenting skills and child efforts maintained over a 1-year period.DESCRIPTORS: autism, behavior management, early intervention, families, generalization, parent train ing, parents Although the need for a more intensive investigation of generalization of parenting skills has been clearly cited in a number of parent training reviews (e.g., Baker,
