To avoid controversies in gene technology such as GMO, there is a must to realize the public attitude and risk perception toward nanotechnology. BACKGROUND OBJECTIVE • To explore the public attitude perception of knowledge, benefit, risk, and trust of nanotechnology in Taiwan. METHODS • Data collection: We conducted a telephone survey in August, 2007, with the computer-assisted Telephone Interviewing system (CSTI) via two-stage geographically stratified systematic sampling collaborated with Academia Sinica. • Sampling population: The study was based on people who were older than 18 and using telephone at home. A total of 1,251 persons successfully completed the telephone interviews, with a completion rate of 17.8%, and a rejection rate of 35.4%. The sample was representative in the distribution of age and gender. • We use Likert four-points to measure the public perception of knowledge, benefit, risk and trust of nanotechnology. One indicated very low and 4 was very high. RESULTS • There were 81.8% of respondents who had heard of nano-products (table1). Participants who were female, younger, higher educated, and unmarried have heard of nano-products more often. • There were some demographic differences in the mean and SD distribution of knowledge, benefit, risk and trust in nanotechnology (table 2). • The correlations of knowledge, benefit, risk and trust in nanotechnology were shown in table 3. • Results of multiple regression were shown in table 4. Sex, education, risk and trust were the major determinants of benefit perception while age, benefit and trust were the determinants of risk perception. Public attitude and Risk Perception of Nanotechnology in Taiwan DISCUSSION and CONCLUSION • Our study indicates that there are risk-benefit trade-offs in the perception of nanotechnology. Other than sex and age, trust plays an important role in determining risk and benefit perception of nanotechnology while knowledge plays a minor role in this study.
