Answer:A sufficiently thorough literature review should be undertaken because many areas of caregiving research are already very well developed. It may be difficult to add new and important information to a given topic. For example, there are already many studies documenting cross-sectional associations of caregiver distress with indicators of caregiving stress, personality, and social support among care recipients with dementia, stroke, cancer, and other prevalent chronic conditions.There are methodological trade-offs that will affect the feasibility of conducting certain kinds of studies. For instance, a project that attempts to identify very homogenous groups of caregivers may have difficulty accruing significant sample sizes.

For instance, a project that attempts to identify very homogenous groups of caregivers may have difficulty accruing significant sample sizes.A project that attempts to recruit African American husbands caring for wives in the aftermath of stroke might be difficult to accomplish because of the relatively low life expectancies of African American men, the likelihood that daughters become the family caregiver for African American women, and the relatively low percentage of older African American women who are married.A sample of caregivers for persons who have recently incurred a spinal cord injury—a condition of relatively low incidence--might also be difficult to recruit within a brief period of time.A sample of parents of children with a rare hereditary cancer syndrome, like Li-Fraumeni Syndrome (about 1000 known cases) would be difficult to accomplish at any single site.
