Does the impact of anti-drinking and driving public service announcements differ based on message type and viewer characteristics?

The purpose of this study was to inform future Public Service Announcement (PSA) development by examining the potential effectiveness of different types of anti-driving under the influence (DUI) PSAs for persons with different characteristics. PSAs utilizing empathy, fear, and informational approaches were shown to persons recruited from psychology courses (n = 137) and individuals that were mandated to treatment following a DUI offense (n = 17). The empathy approach was perceived to be the most effective and evoked the most negative affect, followed by fear and informational approaches. Less experience with DUI, lower sensation seeking, higher motivation to change, and higher perception of dangerousness of DUI all emerged as good predictors of higher perceived effectiveness of anti-DUI PSAs. Gender differences in perceived effectiveness were examined for fear and empathy PSAs, with inconclusive findings.
