Detaillierte Beschreibung
The proposed study will employ a randomized, full factorial experimental design to examine the effects of brief message interventions on parents' acceptance of the first dose of HPV vaccine for their adolescents aged 11-14 years, as well as follow through with subsequent doses. Specifically, the study will employ a 2 x 2 experimental design, in which participants will be assigned randomly to one of two different message sidedness conditions (1 sided vs. 2 sided) and two social compliance conditions (high compliance request [HCR] vs. noHCR). The interventions will be administered by a bilingual research assistant who will read, verbatim, scripts provided to them. Computer assisted telephone interview (CATI) will be used to gather demographic and background information as well as parental health beliefs regarding preexisting worries about HPV vaccine leading to safety concerns (moderator variable) prior to administration of the interventions. After the interventions, additional health beliefs will be assessed (mediators).
- A greater proportion of girls as compared to boys will receive a first dose of vaccine.
- Among both girls and boys who receive a first dose of Gardasil™, no differences in completion rates will be detected.
- The social compliance intervention to be more effective with parents of girls as compared to parents of boys. This prediction of a differential effect is based on the fact that cervical cancer will be seen as a more serious and less stigmatizing condition than genital warts.
In summary, the implementation of this protocol will allow us to systematically examine the use of two different interventions on parents of both boys and girls. Thus, parents (n=800) of 11-14 year old girls and boys will be randomized to the two sets of interventions, resulting in a 2 X 2 design: message sidedness (1-sided; 2-sided) and HCR (yes; no).

Intervention / Behandlung |
|---|---|
|
Experimental: Compliance
Parents will be randomized to receive high or no compliance condition where those in the experimental group will be asked about whether or not they will protect their daughter from cervical cancer or for males, their son from genital warts.
|
Parent will either receive a high or no compliance condition where each is asked to endorse the importance of prevention cervical cancer or genital warts depending on their teen's gender.

Experimental: Message sidedness
Parents will be given either a one-sided verbal message or a two-sided verbal message about the HPV vaccine.
|
Parent will receive either a one-sided or two-sided message about the HPV vaccine
