The purpose of this study is to explore client-nurse interaction from a client perspective with respect to client-centered care. A grounded theory study was conducted with Dutch clients who were chronically ill and receiving home care. Data were collected by focus interviews with 8 client informants, participatory observations with 45 clients, and semistructured interviews with 6 clients. The core category actual interaction was identified. Six patterns of actual interaction were distinguished. Changes in actual interaction could be related to changes in desired participation by the client and in allowed client participation by the professional. From the client's perspective, client-centeredness means congruence between desired and allowed participation. Congruence was experienced with consent, dialogue, and consuming. Congruence is not necessarily synonymous with promoting patient participation or with doing as the client wants. Ongoing attentiveness, responsiveness, promotion of client autonomy, and being a critical caregiver are recommended.
