A pilot study on the neurometric evaluation of 'effective' and 'ineffective' antismoking public service announcements

.Tobacco use is the leading cause of preventable death and smoking-related illness worldwide. Research has shown that antismoking advertising may help reduce this habit. Nowadays, public service announcements (PSAs) are considered “Effective” or “Ineffective” on the base of official reports concerning behavioral/attitudinalchanges toward healthier patterns and health-related savings following the exposure to the PSA. In this pilot study, we described the results of the use of three neurometric indexes for the evaluation of the efficacy of a couple of antismoking PSAs in a reduced sample of voluntary participants. The study applied the gathering of the electroencephalographic (EEG) rhythms variations, as well as the heart rate (HR) and galvanic skin response (GSR). The neurometric indicatorshere employed were the Approach-Withdrawal (AW), the Effort (EfI) and the Emotional (EI) indexes. Results suggest a significant higher values for AW, Effort and Emotional indexes(p=0,02; p= 0,03 and p= 0,01respectively) related to the perception of the “Effective”antismoking PSAs against the perception of the “Ineffective”one. Since this is a pilot study, the results obtained need further investigation, in terms of enlarged stimuli sample and number of participantsto provide indications concerning the relevant features to be included in the realization of effective anti-smoking PSAs.
