Introduction
In an effort to understand why children remain uninsured, Salsberry (2003) interviewed low-income parents in Ohio and compared children with and without insurance. This cross-sectional survey design included a sample of 392 low-income parents. Subjects were chosen from two groups, those with a Medicaid history (n = 305) and those without a Medicaid history (n = 120). Those without a Medicaid history were chosen randomly. Results indicated specific profiles for different levels of insurance. These levels of insurance include uninsured, Medicaid-enrolled, and privately insured. “Statistically significant differences were found across the three groups in income, working status of the adults, education, health status of the adult and child, and in the utilization of health care” (Salsberry, 2003, p. 38). “Parents of the uninsured children were less knowledgeable about the application process. … Parents of uninsured children face multiple life challenges that may interfere with the enrollment process. Health problems, work schedules, and lack of knowledge may all need to be addressed before we can decrease the number of uninsured children in our nation” (Salsberry, 2003, p. 32)
