This document summarizes a study that investigated how two message variables - social topic information and CSR commitment information - influence the effectiveness of CSR advertising. The study found that providing more specific CSR commitment information in ads (rather than just general policy information) significantly reduced consumer skepticism of the ads. However, including social topic information did not significantly interact with commitment information to further reduce skepticism as was hypothesized. The results suggest that consumer skepticism of CSR ads can be inhibited by including more detailed messaging about a company's CSR initiatives and impacts.
