Determinants of Human Papillomavirus (HPV) Vaccination Intent Among Three Canadian Target Groups
ABSTRACT To increase the uptake of the human papillomavirus (HPV) vaccine, understanding the determinants of vaccination intentions for various groups is important. Three studies examining theoretical determinants of college-aged women's (study 1: n = 286), parents' of daughters (study 2: n = 230) and parents' of sons (study 3: n = 137) HPV vaccination intentions were conducted. Participants completed questionnaires assessing constructs of protection motivation theory (PMT) and the theory of planned behaviour (TPB). Results indicate that both PMT and TPB constructs predict intentions for the different groups. Focusing on the response efficacy of the vaccine rather than the severity of contracting HPV may be an effective way to increase vaccination intentions among all groups. Focusing on vulnerability to HPV may only increase intentions among college-aged women and parents of sons, and increasing self-efficacy may only increase intentions among college-aged women and parents of daughters. Findings have implications for understanding differences among groups considering HPV vaccination and tailoring interventions.

ABSTRACT: Viral and bacterial infections are the third leading causes of cancer, after tobacco and diet. 1-3 Approximately 16% of cancers worldwide are known to have an infectious cause, of which 95% are attributed to hepatitis B and C, helicobacter pylori and the human papillomavirus (HPV). 4 HPV accounts for 5.2% of the worldwide cancer burden and is the most common sexually transmitted infection (STI). 5,6 HPV affects 3 out of 4 sexually active individuals at some point in their lives, 7-9 but many may not be aware that they have the virus since HPV is often asymptomatic. Approxi-mately 70% of HPV infections spontaneously resolve within the first year of contracting the virus and 90% spontaneously resolve within 2 years. HPV infection can be spread by skin-to-skin contact (via the genital area), and thus condoms do not fully protect against the virus. 10

ABSTRACT: Little is known about adolescent males and their parents with respect to intent and first dose uptake of the human papillomavirus (HPV) vaccine outside of primay care settings. The purpose of this study was to evaluate potential predictors of parental intent to vaccinate (study was conducted in November 2010-December 2012) and of first dose uptake of HPV vaccine among a sample of young adolescent males, 11-15 years of age, who received care at a school-based health center (SBHC). We also examined intent as a potential mediator of the relationships between predictors (health beliefs and perceived spousal agreement) and vaccination. Slightly more than half (n=135 of 249) of parents reported an intention to vaccinate and 28% (n=69) of males received their first dose of the HPV vaccine. Two of three health beliefs were significantly associated with both intention and uptake as was perceived spousal agreement. We found intention to vaccinate was a partial mediatator between the perceived benefits of HPV vaccine and first dose acceptance. We also determined that intent was a strong mediator between both general immunization benefits and perceived spousal agreement and first dose uptake. While vaccine uptake was lower than expected, particularly considering that many barriers to vaccine initiation were eliminated because of the SBHC setting, this rate is higher than in traditional settings. After controlling for intent, only perceived benefits of the HPV vaccine remained a significant predictor of first dose acceptance.Vaccine 01/2014; 32(17).
