The reliability of the Diabetes Care Profile for African Americans.
The Diabetes Care Profile (DCP) is an instrument used to assess social and psychological factors related to diabetes and its treatment. The reliability of the DCP was established in populations consisting primarily of Caucasians with type 2 diabetes. This study tests whether the DCP is a reliable instrument for African Americans with type 2 diabetes. Both African American (n = 511) and Caucasian (n = 235) patients with type 2 diabetes were recruited at six sites located in the metropolitan Detroit area. Scale reliability was calculated by Cronbach's coefficient alpha. The scale reliabilities ranged from .70 to .97 for African Americans. These reliabilities were similar to those of Caucasians, whose scale reliabilities ranged from .68 to .96. The Feldt test was used to determine differences between the reliabilities of the two patient populations. No significant differences were found. The DCP is a reliable survey instrument for African American and Caucasian patients with type 2 diabetes.
