How anticipated worry and regret predict seasonal influenza vaccination uptake among Chinese adults?
ABSTRACT To test two hypothesized models of how anticipated affect, cognitive risk estimate and vaccination intention might influence vaccination uptake against seasonal influenza.
The study collected baseline and follow-up data during the main influenza seasons (January-March) of 2009 and 2010, respectively, among 507 university students and staff of a university in Hong Kong. Following logistic regression to determine eligible variables, two mediation models of cognitive risk estimate, anticipated affect, vaccination intention and vaccination uptake against seasonal influenza were tested using structural equation modeling.
Mediation analyses found that anticipated worry if not vaccinated influenced seasonal influenza vaccination uptake through its effects on either perceived probability of influenza infection (β=0.45) or intention (β=0.45) while anticipated regret if not vaccinated influenced vaccination uptake through its effect on intention (β=0.45) only; anticipated regret if vaccinated impeded vaccination uptake indirectly through its effect on vaccination intention (β=-0.26) or directly (β=-0.20); perceived probability of influenza infection influenced vaccination uptake through its effect on intention (β=0.20) or directly (β=0.22); and finally, intention influenced vaccination uptake directly (β=0.58).
The results suggest that anticipated affect seems to drive risk estimates related to seasonal influenza vaccination rather than vice versa and intention remains an important mediator of the associations of anticipated affect and cognitive risk estimate with vaccination uptake against seasonal influenza.

ABSTRACT: Background: Seasonal influenza epidemic occurs every year in Guangzhou, which can affect all age groups. Young children are the most susceptible targets. Parents can decide whether to vaccinate their children or not based on their own consideration in China. The aim of this study was to identify factors that are important for parental decisions on vaccinating their children against seasonal influenza based on a modified health belief model (HBM). Methods: A cross-sectional study was conducted in Guangzhou, China. A total of 335 parents who had at least on child aged between 6 months and 3 years were recruited from women and children's hospital in Guangzhou, China. Each eligible subject was invited for a face-to-face interview based on a standardized questionnaire. Results: Uptake of seasonal influenza within the preceding 12 months among the target children who aged between 6 months and 36 months was 47.7%. Around 62.4% parents indicated as being "likely/very likely" to take their children for seasonal influenza vaccination in the next 12 months. The hierarchical logistic regression model showed that children's age (odds ratio [OR] =2.59, 95% confidence interval [CI]: 1.44-4.68), social norm (OR = 2.08, 95% CI: 1.06-4.06) and perceived control (OR = 2.96, 95% CI: 1.60-5.50) were significantly and positively associated with children's vaccination uptake within the preceding 12 months; children with a history of taking seasonal influenza vaccine (OR = 2.50, 95% CI: 1.31-4.76), perceived children's health status (OR = 3.36, 95% CI: 1.68-6.74), worry/anxious about their children influenza infection (OR = 2.31, 95% CI: 1.19-4.48) and perceived control (OR = 3.21, 95% CI: 1.65-6.22) were positively association with parental intention to vaccinate their children in the future 12 months. However, anticipated more regret about taking children for the vaccination was associated with less likely to vaccinate children within the preceding 12 months (OR = 0.21, 95% CI: 0.08-0.52). Conclusions: The modified HBM provided a good theoretical basic for understanding factors associated with parents' decisions on their children's vaccination against seasonal influenza.Chinese medical journal 01/2015; 128(3):327-341.

ABSTRACT: Medically unsupported concerns pertaining to the safety and necessity of childhood vaccines may have contributed to a proportion of American parents opting against measles, mumps, and rubella vaccinations. Given this, the present investigation sought to explore the influence of perceived severity, perceived likelihood, and anticipated regret on surrogate vaccination decision-making among parents of young children. An online survey was distributed to 110 parents with unvaccinated children between 0 and 23 months of age. Significant correlations were found among focal study constructs. Anticipated regret was found to fully mediate the link between risk perceptions and vaccination intentions. The practical and theoretical implications of these findings were discussed.Psychology Health and Medicine 05/2014; DOI:10.1080/13548506.2014.911923 · 1.53 Impact Factor

ABSTRACT: Objectives: The paper examines the factors associated with both receiving pandemic (H1N1) 2009 vaccines and individuals' intentions to get the next seasonal influenza vaccine in Taiwan. Methods: We conducted a representative nationwide survey with in-person household interviews during April-July 2010. Multivariate logistic regression incorporated socio-demographic background, household characteristics, health status, behaviors, and perceptions of influenza and vaccination. Results: We completed interviews with 1,954 respondents. Among those, 548 (28.0%) received the pandemic (H1N1) 2009 vaccination, and 469 (24.0%) intended to get the next seasonal influenza vaccine. Receipt of the H1N1 vaccine was more prevalent among schoolchildren, the elderly, those who had contact with more people in their daily lives, and those who had received influenza vaccinations in previous years. In comparison, the intention to receive the next seasonal influenza vaccine tended to be stronger among children, the elderly, and those who reported less healthy status or lived with children, who received a seasonal influenza vaccination before, and who worried more about a possible new pandemic. Conclusions: Children, the elderly, and those who had gotten seasonal flu shots before in Taiwan were more likely to both receive a pandemic H1N1 vaccination and intend to receive a seasonal influenza vaccine.PLoS ONE 06/2014; 9(6):e101083.
