Abstract

Objective: Information overload can negatively impact positive health behaviors such as cancer screening.The 8-item Cancer Information Overload (CIO) scale appears to be the only validated measure of healthrelatedinformation overload. The present study assesses the validity of the CIO scale when modified foruse in patients with atrial fibrillation (AF) residing in Australia.Methods: We conducted a secondary analysis of data from a study of adult Australian patients with AF(N = 386) in which a modified version of the CIO scale was used. In the present study, we examined theconstruct (convergent and divergent) validity and performed an exploratory factor analysis for themodified scale.Results: All items on the modified-CIO scale appear to load onto a single factor. As predicted, highereducation levels (rs=-.24, ps=-.17, p = .001) weresignificantly associated with lower modified-CIO scores; no other demographic characteristics weresignificantly associated with CIO scores.Conclusion: When adapted to the AF context, the modified-CIO scale appears to be a valid measure ofinformation overload.Practice Implications: A valid scale is required to measure information overload accurately. Knowledge ofthe interplay between information overload and various health behaviors help focus future efforts tosupport patient empowerment.
