Effects of Web Interactivity: A Meta-Analysis

<jats:p> Over the last few years, significant research has been conducted to examine the impact of web interactivity. However, mixed results have been found regarding why and how web interactivity could affect users’ attitudes and other psychological responses. This meta-analysis reviewed prior research that examined the extent to which web interactivity could affect various psychological outcomes and how such effects would differ due to several moderating variables. Our analysis of the results in 63 studies ( N = 13,484) suggested that across studies, web interactivity was significantly correlated with user enjoyment, positive attitudes, and desirable behavioral intentions. However, interactivity did not necessarily increase cognitive elaboration, knowledge acquisition, and information recall. While modality interactivity appeared to be more effective than source interactivity and message interactivity, perceived interactivity was significantly more effective than objective interactivity. Furthermore, extremely high levels of web interactivity were not as effective as have been anticipated. </jats:p>
