OBJECTIVE: To examine behavioral history, beliefs, and vaccine characteristics as predictors of HIV vaccine acceptability. METHODS: Two hundred forty-five US undergraduates were surveyed regarding their sexual history, risk beliefs, and likelihood of accepting hypothetical HIV vaccines. RESULTS: Multivariate regression analysis indicated that vaccine acceptability was predicted by lifetime sexual partners, high perceived HIV susceptibility, low danger invulnerability, and high psychological invulnerability. Low perceived risk was associated with basing decisions on vaccine cost. CONCLUSIONS: HIV vaccine acceptability was predicted by behavioral risk and perceived HIV susceptibility, but also by general feelings of invulnerability to physical and psychological harm.

Background: Future successful sexually transmitted infection (STI) vaccine programs will depend on health professionals' readiness to vaccinate adolescents.Goal: The goal was to examine nurse practitioners' willingness to recommend STI vaccines to parents of adolescent patients.Study Design: Participants rated 13 hypothetical vaccine scenarios, each of which was defined along 4 dimensions: infection; patient age, patient gender, and American Academy of Pediatrics (AAP) endorsement. Conjoint analysis was used to determine the relative contribution of each dimension to the ratings.Results: Generally, participants were amenable to recommending STI vaccines. Conjoint analysis indicated that AAP recommendation, infection, and patient age most strongly influenced ratings. There was particular interest in an HIV vaccine, but there was reluctance to vaccinate younger adolescents or to vaccinate without AAP endorsement.Conclusions: Nurse practitioners are willing to recommend STI vaccines to parents of adolescents. Professional organization endorsement plays an important role in this decision. Younger-aged adolescents were not viewed as candidates for these vaccines. [ABSTRACT FROM AUTHOR]

Background and Objectives: The development of a vaccine to prevent human immunodeficiency virus (HIV) infection is a highly desirable goal. However, there may be a number of psychosocial barriers to HIV vaccine acceptance. The purpose of this study was to begin to examine some factors that might influence attitudes about HIV immunization.Goal: To evaluate the relationship of health beliefs and vaccine characteristics to acceptability of hypothetical HIV immunization.Study Design: The subjects were 222 college students who completed self-administered questionnaires that addressed health beliefs, vaccine characteristics, and acceptability of hypothetical HIV vaccines.Results: Health beliefs independently predictive of HIV vaccine acceptability included perceived susceptibility to HIV, perceived nonmembership in a traditionally defined acquired immune deficiency syndrome (AIDS) risk group, and fear of the vaccine causing AIDS. Of the vaccine characteristics, efficacy influenced vaccine acceptability most strongly, followed by type of vaccine.Conclusion: These results suggest that universal HIV vaccine acceptance cannot be assumed and that vaccine characteristics and individuals' health beliefs are likely to influence decisions regarding HIV immunization.

Background and Objectives: Little is known about the acceptability of vaccines for prevention of sexually transmitted diseases (STDs). The purpose of this study was to examine potential predictors of genital herpes simplex virus type 2 (HSV-2) vaccine acceptability.Goals: To evaluate the relationship of health beliefs and health behaviors to HSV-2 vaccine acceptability.Study Design: Three hundred twenty-one subjects participating in two phase III clinical trials for an HSV-2 vaccine completed surveys addressing health beliefs, health behaviors, and acceptability of hypothetical HSV-2 vaccines.Results: Bivariate analyses found that perceived benefits of vaccination, seatbelt use, a healthy diet, and having had cholesterol levels checked were associated with higher acceptability. Perceived limitations of HSV-2 immunization, alcohol use, and exercise were associated with lower acceptability. Multiple regression analysis identified perceived benefits of vaccination, decreased exercise, and lower alcohol use as significant independent predictors of greater HSV-2 vaccine acceptability.Conclusions: In groups of high-risk individuals who had completed participation in HSV-2 clinical trials, health beliefs and health behaviors influenced acceptability of hypothetical HSV-2 vaccination. The findings support the need to understand determinants of acceptance of vaccines for HSV-2 and other STDs. [ABSTRACT FROM AUTHOR]

Several vaccines for sexually transmitted infections (STI) are presently in development and the eventual availability of such vaccines is expected to result in the prevention of a significant number of burdensome conditions. Young adolescents are presumed to be likely targets for these vaccines since adolescents' risk for STI increases as they age and become sexually active. It is unclear, however, to what extent parents will agree to having adolescents receive STI vaccines. Inasmuch as acceptance is the foundation for effective immunization programs, an understanding of parental perspectives about this issue is required to inform future STI vaccine program strategies. This paper presents findings from a qualitative study that used in-depth interviews to elicit attitudes from 34 parents about accepting vaccines for genital herpes, human immunodeficiency virus, human papillomavirus and gonorrhea for their children (aged 8-17). Data were collected from parents bringing their children for care at an urban clinic and a suburban private office. Content analysis of the responses revealed that most parents (>70%) approved the administration of all four of the STI vaccines proposed. Parents' reasons for acceptance included wanting to protect their children, being concerned about specific disease characteristics, and previous experience with the infections. Parents who declined the vaccines did so primarily because they perceived their children to be at low risk for the infections or they had low concern about features of the diseases. Most parents thought they should be the decision-maker regarding children receiving an STI vaccine. Results from this study will be used to plan subsequent investigations of the determinants of STI vaccine acceptance by parents. [ABSTRACT FROM AUTHOR]

Little is known about the bases of parental worry about adolescents' risk for acquiring a sexually transmitted infection (STI). Parents (N = 247) of adolescents 12-17 years endorsed reasons that explained their worry or nonworry. Parents' past experience of an STI, perception of the child's sexual activity, and racial self-identification were predictors of worry. Cluster analyses identified five groups of worriers and four groups of nonworriers. Worriers tended to select reasons reflecting an external parental locus of control or child-specific reasons. Nonworriers endorsed reasons consistent with internal parental locus of control. Findings suggest that preventive health communication should be tailored to parents' perceptions of risk and protective factors. Copyright 2008 SAGE Publications. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Health beliefs have been found to be significant predictors of vaccine acceptability and uptake, including attitudes about HPV vaccine. In this study, we examined whether the predictive strength of health beliefs varied as a function of vaccine cost among adult women. METHODS: During April 2009, data were collected from a nationally representative internet sample of 1323 US-resident women aged 27-55years. Participants completed items related to sociodemographics, health beliefs, and HPV vaccine acceptability. Acceptability was measured at three levels of cost: free, $30/dose, and $120/dose. RESULTS: Multiple linear regression (MLR) revealed that health belief variables accounted for 29.7% of the variability in overall HPV vaccine acceptability. However, there was a linear and significant decrease in R(2) values from 0.31 for a free vaccine, to 0.25 for a $30/dose vaccine, to 0.11 for a $120/dose vaccine. CONCLUSION: The results confirm previous findings that health beliefs predict HPV vaccine acceptability. However, the predictive strength of the association decreased with increasing cost. These findings suggest that interventions designed to increase vaccination by modifying health beliefs may have limited effect unless cost is minimized as a barrier. [ABSTRACT FROM AUTHOR]
