While defaults may encourage some health behaviors, how defaults influence controversial behaviors is not well understood. We examined the effect of two default policies on parents' consent to have their adolescent sons hypothetically receive HPV vaccine at school. A national sample of 404 parents of adolescent sons participated in an online 3 × 2 between-subjects factorial experiment. Factors varied the default consent policy (opt-in, opt-out, or neutral) and the number of vaccines sons would receive (HPV vaccine alone or along with two other recommended adolescent vaccines). Among parents wanting to get their sons HPV vaccine in the next year, consent was higher in the opt-in condition (compared to the opt-out condition) or if other recommended adolescent vaccines would be included. Default policies had no effect among parents undecided about HPV vaccination. Parents' consent for school-located HPV vaccination may be higher when presented as an opt-in decision and other vaccines are included.
虽然默认设置可能会鼓励一些健康行为,但默认设置如何影响有争议的行为尚不清楚。我们研究了两种默认政策对父母同意其青春期儿子在学校假设接种人乳头瘤病毒(HPV)疫苗的影响。一项针对404名青春期儿子的父母的全国性样本参与了一项在线3×2组间析因实验。因素包括默认同意政策(选择加入、选择退出或中立)以及儿子将接种的疫苗数量(仅HPV疫苗或与另外两种推荐的青少年疫苗一起接种)。在希望明年让儿子接种HPV疫苗的父母中,选择加入条件下(与选择退出条件相比)或如果包括其他推荐的青少年疫苗,同意率更高。默认政策对未决定是否接种HPV疫苗的父母没有影响。当作为选择加入的决定并包括其他疫苗时,父母对在学校接种HPV疫苗的同意率可能会更高。
