The authors examined the extent to which parent expectations, perceptions about resource availability and supports, and strategies used to promote participation in home and community activities varied by setting and activity type. Sixteen 90-min semistructured interviews were completed with families receiving Part C early intervention services in three states. Interviews were analyzed in descriptive and interpretive phases using content analysis to identify patterns across cases and logical analysis to cross-classify data and identify patterns by setting and activity type. Parents described how often and how much their children participated but had different ways of describing their expectations depending on the activity setting and/or its purpose. Parent-reported strategies to promote participation provided a direct way of understanding how environments were perceived to impact participation. Implications for tailoring interventions to address the needs of immigrant and nonimmigrant families receiving Part C services are discussed. (Contains 3 tables.)
