In what ways does user experience design improve printed educational materials?

Abstract

We report on a series of four studies that investigated how user experience design (UXD) can improve printed educational materials (PEMs). We examined the perceived usability of an existing PEM for breast cancer screening and observed the usability problems associated with it (Study 1). We then compared a breast cancer screening PEM created by user experience designers with two other breast cancer screening PEMS, finding that the PEM based on UXD had higher perceived usability, and lower mentions of usability problems, than the other two PEMs (Study 2). We next examined the impact of individual differences in design expertise on perceived usability, this time including a PEM on cervical cancer screening as well as one on breast cancer screening (Study 3). Our concluding study (Study 4) then examined the impacts of UXD on learnability of PEM content as defined by answers to a knowledge questionnaire about screening administered before and after reading the PEM, and by intention to screen for cancer after reading the PEM. The first three studies showed that the involvement of UXD improved the perceived usability of PEMs, and Study 3 showed that designers differ in their ability to create useable PEMs. Study 4 failed to find a corresponding improvement in learnability or intention to screen when UXD was used to improve perceived usability. We conclude that a user experience design approach that incorporates graphic design can improve the perceived usability of PEMs in some situations (e.g., when the PEM material is not too lengthy or complex, and when the graphic designer is sufficiently skilled). However, we found no evidence that lack of perceived usability accounted for the failure of PEMS (found in previous research) to improve knowledge or intention to screen.
