Identifying the public's knowledge and intention to use human cloning in Greek urban areas.

Purpose: The understanding of the public's knowledge on human cloning (HC) and its acceptability are considered important for the development of evidence-based policy making. The aim of this research study was to investigate the demographic and socioeconomic variables that affect the public's knowledge and intention to use HC in urban areas of Greece. Additionally, the possible association of religiousness with the knowledge and the intention to use HC were also investigated.

Methods: Individual interviews were conducted with 1020 men and women of urban areas in Greece. Stratified random sampling was performed to select the respondents. Several scientists, experts in HC, evaluated the content of the instrument initially developed. The final questionnaire was consequently the result of a pilot study.

Results: Almost half of the respondents (51.5%) believed that "HC is a sort of in vitro fertilization" and 42.9% that "it has already been applied to human being." They were not aware that "the cloned fetus grows in the woman's uterus" (41.5%) and that "HC could regenerate human organs" (41.7%). The acceptability of human cloning for the cure of terminal diseases and transplantation need is very high (70.7% and 58.6%, respectively). The public's intention to have recourse to cloning on the grounds of "bringing" back to life a loved person or because of reproductive disorders was reported as desire by 35% and 32.5%, respectively. The occupational category (scientists, self-employed, and artists), the Intention to use HC, and the number of children are highly significant predictors of valid knowledge about HC. Low rates of church attendance appeared to relate with high reported Intention to use HC, and increasing scores of valid knowledge about HC increased the public's Intention to use HC.

Conclusions: A number of specific demographic and socioeconomic characteristics and high scores of knowledge provide a persuasive justification in demonstrating intention toward HC. The current study suggests that these findings should receive further attention by policymakers and scientists within the Greek context.
