The purpose of this study was to assess the psychometric properties of a cardiovascular health knowledge measure for adolescents using item response theory. The measure was developed in the context of a cardiovascular lifestyle intervention for adolescents with elevated blood pressure. Sample consisted of 167 adolescents (mean age = 16.2 years) who completed the Cardiovascular Health Knowledge Assessment (CHKA), a 34-item multiple choice test, at baseline and post-intervention. The CHKA was unidimensional and internal consistency was .65 at pretest and .74 at posttest. Rasch analysis results indicated that at pretest the items targeted adolescents with variable levels of health knowledge. However, based on results at posttest, additional hard items are needed to account for the increase in level of cardiovascular health knowledge at post-intervention. Change in knowledge scores was examined using Rasch analysis. Findings indicated there was significant improvement in health knowledge over time [t(119) = -10.3, p< .0001]. In summary, the CHKA appears to contain items that are good approximations of the construct cardiovascular health knowledge and items that target adolescents with moderate levels of knowledge.  DOI:10.2458/azu_jmmss_v3i1_fitzpatrick

Latent Traits

Item response theory has its origins in educational measurement and is now commonly applied in health-related measurement of latent traits, such as function and symptoms. This application is due, in large part, to gains in the precision of measurement attributable to item response theory and corresponding decreases in response burden, study costs, and study duration. The purpose of this paper is twofold: introduce basic concepts of item response theory and demonstrate this analytic approach in a worked example, a Rasch model (1PL) analysis of the Eating Assessment Tool (EAT-10), a commonly used measure for oropharyngeal dysphagia. The results of the analysis were largely concordant with previous studies of the EAT-10 and illustrate for brain impairment clinicians and researchers how IRT analysis can yield greater precision of measurement.
