Filter by:The investigators will recruit a national sample of parents of 7-10-year-olds to complete an argument strength ranking for either a simple forwarding message or between 3 and 6 randomly selected arguments from an overall set of 50 to 100 messages identified from various online sources. Parents will rate each message they see on measures of perceived argument strength/PME. Parents will also answer sociodemographic questions and then rank the believability of a set of anti-vaccine messages identified in a different study. Study findings will contribute valuable information to understanding the effectiveness of different inoculation messages.
This study will take place at health centres and their affiliated schools and community immunization centers overseen by the Kampala Capital City Authority (KCCA) as well as at the Makerere/Mulago/Columbia Adolescent Health Clinic, also in Kampala. While text messages can be used in populations with low literacy, families can opt to receive automated phone call reminders instead. The investigators will pilot assess the impact of vaccine reminders on human papillomavirus (HPV) vaccination. Caregivers of preteens/adolescents will be randomized and stratified by site, language and HPV vaccine dose needed (initiation vs. completion). As this is a feasibility trial, the investigators expect to measure effect size but not necessarily achieve statistical significance.
The overall objective is to document geographic variability in HPV vaccine series completion across the state of Indiana and to identify factors associated with low versus high rates of completion. Objective a: To map HPV vaccine series completion rates across Indiana's 92 counties for children aged 14 years and younger. Hypothesis: The investigators expect wide variability in completion rates from county to county. Further, the investigators expect significantly less variability in county-level administration of vaccines required for middle-school entry (Tdap, MenACWY, and HepA vaccines). Objective b: To identify county-level characteristics associated with HPV vaccine series completion rates across Indiana's 92 counties. Hypothesis: The investigators expect factors reflective of pragmatic obstacles to be associated with lower completion rates: such as lower population density, fewer primary health care providers (HCP) per capita, longer commute to work, lower median household income, and lower rates of insurance coverage of children.
The objectives of this study are: 1. To better understand factors associated with acceptance and refusal of HPV vaccine among parent-son pairs and the process of parent-son decision-making with respect to vaccination. 2. To evaluate health care providers (HCPs) attitudes, implementation intentions, and planned communication strategies with respect to HPV vaccination of adolescent boys. Hypothesis 1: Sons will have a significant role in the process of parent-son decision-making about HPV vaccination. The relative importance of this role will increase with the son's age. Hypothesis 2: Pediatric HCPs will be unsure about vaccinating males and will lack knowledge about issues related to male HPV infection and vaccination.
