Predictive Power Enhanced: Analysis of Remote Facial Expressions Boosts Perceived Efficiency in Selecting Anti-Tobacco Public Service Announcements
A groundbreaking study has demonstrated that the combination of facial expression analysis and perceived effectiveness (PE) can significantly improve the prediction of quit smoking intentions among tobacco users, particularly in remote, online surveys.
The research, which involved 302 participants, each watching three different anti-tobacco public service announcements (PSAs), found that this dual method captures both conscious evaluations (PE) and unconscious emotional reactions (facial expressions). This approach offers additional predictive value beyond PE by providing objective emotional data, improving the assessment of PSA impact in remote settings.
Metrics for 'attention' (head position) and 'facial action units' (FAU) were computed from webcam videos transmitted during the study. The results suggest that the combination of Attention, FAU, and PE can be a useful tool in identifying tobacco users who are more likely to quit smoking.
Interestingly, the study did not report any specific PSAs that were the most effective overall. However, it did indicate that surprising ads had a preference among those who were 'ready to quit' (RTQ). Both RTQ and 'not ready' (NR) respondents favoured the same PSAs, but RTQs assigned higher PE scores, indicating a stronger perceived impact.
Negative PSAs ("sad" or "frightening") were more compelling overall, but RTQs also favoured surprising ads and were more willing to share them on social media. This finding suggests that a mix of emotional approaches could be effective in engaging tobacco users and encouraging them to quit.
The study's findings add to the growing body of evidence that supports the use of objective, real-time emotional responses, such as those provided by facial expression analysis, in health messaging like anti-tobacco campaigns. By quantifying subtle emotional cues like disgust, fear, sadness, or anger, this method offers a valuable complement to subjective measures like PE.
Further research is needed to precisely quantify the added predictive power of this combined approach. However, the current study provides a strong foundation for the potential of this method in enhancing the prediction of quit smoking intentions among remote tobacco users.
