A future for family care and dementia intervention research? Challenges and strategies.

Despite widespread interest in the challenges facing family caregivers of people with dementia, the literature on empirically-validated treatments has grown slowly. One issue that has limited its growth has been that many of the existing treatment trials show weak or only modest benefits on caregiver outcomes. An examination of the literature suggests that the research strategies used for testing the effectiveness of interventions have not been optimal and the limitations in their approaches may have contributed to their limited findings of improvement. We identify some of the methodological issues that may have affected previous trials and suggest strategies for addressing these issues.
