RESUMO
PURPOSE: The purpose of this pilot study was to assess (1) the reliability of the revised Wallhagen Perceived Control Questionnaire (PCQ-R), derived from a person-environment perspective, in a sample of elderly African Americans > or = 60 years with Type 2 diabetes and (2) the relationship between the PCQ-R and psychosocial and physiological functioning. METHODS: A descriptive, cross-sectional, pilot project was conducted with a convenience sample of 23 African Americans with Type 2 diabetes. Variables included health status, the PCQ-R, the Medical Outcomes Survey Short Form 36, and glycosylated hemoglobin. RESULTS: The PCQ-R was reliable and significantly related to physical and social functioning, physical and emotional role involvement, mental health, vitality, and general health perception. No relationship was found with metabolic control. CONCLUSIONS: Findings support the reliability of the PCQ-R and the conceptualization of control. However, confirmation is needed in a larger sample, and questions that emerged require further exploration.
