F OR three reasons, we would like to thank Zarit, Stephens, Townsend, Greene, and Femia (2003) for opening the discussion about the effectiveness of day care for caregivers in their response to our article ‘‘Evaluation of Geriatric Day Care Units: Effects on Patients and Caregivers’’ (Zank & Schacke, 2002). First, we discussed our results cautiously and did not conclude that day care is ineffective for caregivers. Yet, we do agree that there is a possibility of political misuse of our data. We certainly did not intend to support political decisions against day care. Second, the commentary gives us a chance to report our complex multimethodological approach and results that were beyond the scope of the original article (Zank & Schacke, 2002). Third, some of the issues raised could be due to differences between the American and the German health and care systems, which will be described later. When we started our study in 1994, we were very much aware of the risk that standardized measures might not grasp certain effects that day care might have on caregivers. We, therefore, applied a multimethod approach. First, we chose the most prominent standardized measures at that time, namely, the Burden Interview (BI) and the Memory and Behavior Checklist (Zarit & Zarit, 1983/1990), and the Family-Caregiving Conflict and Job-Caregiving Conflict scales (Pearlin, Mullan, Semple, & Skaff, 1990). These quantitative data failed to show positive effects of day care on caregivers. We will give detailed reasons for our choice of instruments later (see Criterion 4). Second, to examine the caregiver’s stress, we developed a semistructured qualitative interview based on stress theory. This interview took approximately an additional 1–1.5 hr to administer. We conducted these qualitative interviews twice with caregivers of dementia patients only (N 1⁄4 37, T1, and, after 9 months, T2 1⁄4 74 interviews). As the first step, we analyzed these qualitative interviews by using content-analytical techniques (Mayring, 1988). Then, to allow further statistical analyses, we developed response scales to measure the intensity of caregiving stress. Results from the analyses of variances of these data show that day care significantly reduced conflict between caregiving and job requirements, caregiving and family needs, and recreational constrictions. Initial results from these qualitative data were published in German (Schacke, 2001; 2002, Zank & Schacke, 2001, Zank, 2000), and an English article has been submitted (Schacke & Zank, 2002). These results convinced us that day care is effective, not only for patients but also for caregivers; nevertheless, we have to accept that the results based on the standardized measures did not reflect this conclusion. Zarit and colleagues (2003) suspected several methodological flaws in our quantitative data that could explain our results. In the following, we will explain why we think that these methodologicial flaws did not exist. Finally, we will explain our interpretation of the results and consequences we drew.
