在與2,028位18歲以上的台灣公民中進行了面對面的採訪後，調查結果顯示，只有報紙的使用與公民參與有正向預測的關係。而新聞媒體的使用和公民對選舉的憂慮並沒有間接影響。但是，在對電視新聞信任程度較低的族群中，人們對選舉的焦慮程度對電視新聞使用與公民參與產生間接的影響。人們對電視新聞的信任可以調節電視新聞使用與人們對選舉的焦慮的關係。但是，對媒體的信任無法調節新聞媒體的使用與人們的公民參與的關係。總之，本研究為媒體效應理論構建中的不同因素帶來了新的見解。

Civic engagement is a practice of democracy in Taiwan, and mass media plays an important role in disseminating information in the community. Previous studies have found that informational use of media may predict people’s willingness to join in civic and political life. In the past years, the impact of media use on people’s participatory behaviors has long been investigated. However, limited studies explored the affective effects and the perception of media effects, including media trust, on people’s behaviors. The present study differentiates three different news media platforms to examine the role of emotional response and media trust in the relationship between news media exposure and civic engagement in Taiwan. This study employed the 2018 Taiwan National Communication Survey (TCS) dataset. The face to face interviews was conducted among 2,028 Taiwanese citizens, who were 18 years or older. Findings indicated that only newspaper use was positively related to civic engagement. There were no indirect effects of news media exposure and civic engagement through anxiety about the election. However, the conditional indirect effects showed that the indirect effect of television news exposure on civic engagement difference through anxiety about the election was significant in lower levels of trust in television news conditions. Trust in television news was found to moderate the relationship between television news exposure and people’s anxiety about the election. However, trust in the media could not moderate the association between news media use and people’s civic engagement. In sum, this study brings new insight into the different factors in media effects theory building.
