Type 2 diabetes has reached epidemic proportions among all races in the United States. The extent to which individuals' perceptions of risk factors for type 2 diabetes are related to their actual risks and health-promoting behaviors is not well known. Yet perception of risk factors for type 2 diabetes may influence the likelihood that individual would engage in preventive behaviors. Thus, the purpose of the study was to evaluate the psychometric properties and factor structure of the perception of risk factors for type 2 diabetes scale. A descriptive, correlational, and methodological design was used to conduct this study. The sample consisted of 629 adults from 42 states of the United States. A demographic questionnaire, the perception of risk factors for type 2 diabetes scale, the health-promoting lifestyle profile II, and the depressive cognition scale were used to collect the data. Data analyses consisted of descriptive statistics, scale and item analyses, Pearson's correlation, and exploratory and confirmatory factor analyses. The results showed that all statistical estimates were above the standard recommended criteria: Cronbach's alpha was .81; item-to-total correlations for each factor were between r = .30 and r = .70; and selected model fit indices were above .90. The perception of risk for type 2 diabetes scale has the potential to be a useful measure in research and clinical practice to examine the congruence between an individual's level of perceived risk and that individual's actual risk for type 2 diabetes. It is a valid and reliable measure, and its factor structure fit the data well. Further psychometric testing of the measure is warranted, especially among homogenous samples of population groups at increased risk for the development of type 2 diabetes, such as Hispanic/Latinos and African Americans.
