Stories to Prevent (StoP) HPV Cancers: A communication intervention to increase HPV vaccination among diverse populations
Objective
Aim 1. Evaluate the association of a narrative communication intervention on HPV vaccination rates among 9- to 12-year-olds. We will recruit six local cancer survivors diagnosed with an HPV-related cancer and record their narratives for the intervention videos. RCT participants will be the parents (n=200) of children ages 9-12 who have not initiated HPV vaccination. Participants will be randomized (1:1) to our intervention or control one week before their child s next primary care visit. Our primary outcome is HPV vaccine initiation (≥1 dose) among children ages 9-12 at the time of the wellness visit. We hypothesize that (H1) the rate of HPV vaccination among children of parents exposed to the intervention will be 20% higher than in the control arm.
Aim 2. Explore the effect of narratives on theory-based mediators of HPV vaccination. We hypothesize that (H2) narratives will enhance parents cognitive (e.g., risk perception) and emotional reactions (e.g., hope, anticipated regret) to HPV vaccination, and (H3) cognitive and emotional reactions will moderate the relation between narrative communication and HPV vaccine initiation.
