A Non-randomized,Quasi-Experimental Comparison of Effects Between an In-person and Online Delivery of a College Mental Health Literacy Curriculum

Mental health literacy (MHL) training is essential in college environments. These programs are commonly delivered in-person via workshops or for-credit courses. Campuses now seek high-quality online options. We compare the effectiveness of a for-credit MHL course against a comparison course, focusing on whether online asynchronous delivery was as effective as in-person synchronous delivery. This quasi-experimental pretest/posttest treatment/comparison study included 1049 participants across five semesters (pre-COVID-19) who were 18 years or older and self-selected enrollment in a Mental Health Awareness and Advocacy (MHAA) course (treatment; n?=?474) or a general lifespan development course (comparison; n?=?575). Using linear mixed effect modeling, changes in MHL were compared across groups and across online/in-person modalities. Students in the treatment group significantly increased their MHL knowledge (β _Identifying?=?.49, p?<?.001; β _Locating?=?.32, p?<?.001; β _Responding?=?.46, p?<?.001) and self-efficacy (β?=?.27, p?<?.001), and treatment effects did not differ across modalities. With increased concern regarding mental health issues of isolated college students during the COVID-19 pandemic, this study supports the efficacy of delivering MHL courses online.

     

Characteristics associated with the willingness to receive a COVID-19 vaccine and an exploration of the general public's perceptions: A mixed-methods approach

Demographics and media discourse impact vaccine hesitancy. We explored the New Zealand public's perceptions of COVID-19 vaccines and associated media portrayal, and determined predictive factors associated with willingness to receive vaccines. A community cohort (N = 340) completed online surveys. A logistic regression explored whether characteristics predict willingness to receive the vaccine. Textual data were analysed thematically. Willingness to receive the vaccine was high (90%). Having a postgraduate degree (p =.026), trying to receive an influenza vaccine (p <.001) and fewer concerns (p <.001) predicted willingness. Health keyworkers (p <.001) were less willing. Participants wanted the vaccine for protection and returning to normality. Reasons against receiving vaccines regarded safety, efficacy, and an unclear roll-out plan. The media was reported to generally provide good/positive coverage, but also engage in unbalanced reporting and spreading misinformation. Education strategies should include collaborations between media and scientists and focus on distributing easy-to-access information. Health keyworkers should be reassured of testing/safety.     

Prevalence,determinants, and reasons for malaria vaccine hesitancy among caregivers of under-five children in Nigeria: Results from a nationwide cross-sectional survey

ObjectiveMalaria contributes to an enormous global burden of disease and mortality, especially in children. Approximately one in every four global cases and deaths from malaria occurs in Nigeria. This study aims to evaluate the prevalence and correlates of community hesitancy to the malaria vaccine, including the reasons for the hesitancy, following the approval of the RTS,S malaria vaccine by the World Health Organization (WHO).MethodsThis was a nationwide cross-sectional online survey of Nigerian adults conducted from 20th October to 30th November 2021. Participants who replied ‘no' or ‘maybe’ to a question assessing their willingness to accept the RTS,S malaria vaccine were considered “hesitant”. We fit a multivariate logistic regression model to report the adjusted odds ratio (aOR) and 95 % confidence interval (CI) for the factors associated with vaccine hesitancy.FindingsAmong 3377 total respondents (1961 [57.86 %] males; mean age [SD]: 30[9.1]), 1010 (29.91 %) were hesitant. Receiving information about the RTS,S malaria vaccine initially from healthcare workers (vs. the internet) (aOR:0.55; 95 % CI:0.35–0.87) was significantly associated with lower odds of hesitancy. Conversely, earning a high income of over NGN100, 000 (vs. < NGN 30,000) per month (aOR: 2.10, 95 % CI: 1.36–3.24), belonging to other religious groups (vs. Islam) (aOR:3.25, 95 % CI:1.18–8.98), and having a family size of more than ten (vs. < 5) (aOR:1.84; 95 % CI:1.08–3.13) were significantly associated with a higher odds of hesitancy. The main reasons for vaccine hesitancy included fear of vaccine adverse effects (34.95 %), availability of other malaria preventive measures (33.96 %) and not seeing the positive effect of the vaccine in others first (32.97 %).ConclusionThe findings of this survey provide a valuable blueprint for the development of targeted interventions to facilitate caregiver acceptance of the RTS,S vaccine.     

Sociodemographic and psychological correlates of COVID-19 vaccine hesitancy and resistance in the young adult population in Italy

BackgroundPrevious research has shown that young adults are more hesitant/resistant to COVID-19 vaccine uptake than older age groups, although the factors underlying this tendency are still under debate. The current study aimed to identify the sociodemographic and psychological correlates of vaccine hesitancy and resistance among young adults (18–40 years) during the nationwide COVID-19 vaccination campaign in Italy, the first country after China being hit by the pandemic and which suffered a large number of fatalities.MethodsThis is a cross-sectional, web-based study conducted in Italy using an ISO-certified international survey company (respondi.com). Data were collected on 1200 participants in June 2021.ResultsVaccine hesitancy/resistance was found for 25% of the sample. In multinomial logistic regression (N = 1159), being aged 30–40 years, residing in northern Italy, having lower educational and income level, being unemployed, and not knowing any friends/relatives diagnosed with COVID-19 were associated with higher odds of hesitancy or resistance. In multivariate analysis of variance (N = 1177), both vaccine hesitant and resistant young adults perceived significantly less social support from friends and family than vaccine accepting ones. Resistant individuals reported significantly higher levels of conspiracy theories and negative attitudes toward vaccines than their accepting and hesitant counterparts. Moreover, resistant individuals reported significantly lower levels of attachment to country and perceptions of a just government compared to accepting ones, with hesitant young adults scoring in between.ConclusionsOur findings support the idea that young adults with a hesitant (vs. resistant) attitude show a more nuanced and less extreme psychological profile. Public health messaging should capitalize on social media to provide accessible, transparent, and age-appropriate information concerning COVID-19 vaccine safety. Moreover, policy efforts improving the availability of social support systems are warranted to strengthen connectedness and foster trust in institutions amongst this particular segment of the population.     

Results of CINDI Health Monitor surveys in Slovenia as a tool for development of effective healthy nutrition and physical activity intervention programmes

Aim: The study was conducted aiming at assessing the prevalence of several selected health behaviours and on identifying population groups at very high risk for them in the adult population. The present study focused on unhealthy nutrition related to obesity and diabetes (UNROD) and insufficient physical activity (IPA). High-quality basis for working out strategies, guidelines and plans for public health action in Slovenia was planned to be prepared. Subjects and methods: The data originate from the national survey carried out in 2001 on health behaviour of 15,379 adults aged 25–64 based on Countrywide Integrated Non-communicable Diseases Intervention (CINDI) Health Monitor (CHM) methodology. The overall response rate of the mailed questionnaire was 64%, with 9,043 questionnaires being eligible for analysis. Binary multiple logistic regression was used to determine the impact of gender, age, education, employment, self-assessed social class, type of residence community and geographical region on the occurrence of UNROD and IPA. Results: The highest odds for UNROD were registered in men [odds ratio (OR)_{men vs. women}=1.35, p<0.001], aged 25–29 (OR_{25–29 vs. 60–64}=2.72, p<0.001), participants with primary education level (OR_{primary vs. university education}=2.20, p<0.001), heavy workers in rural economy (OR_{heavy work in rural economy vs. pensioner}=1.85, p<0.001), participants self-classified in labour social class (OR_{labour vs. upper}=1.89, p=0.026); residents of rural communities (OR_{rural vs. urban residence community}=1.26, p<0.001), and participants from the eastern region of Slovenia (OR_{eastern vs. central}=1.43, p<0.001). The highest odds for IPA were registered in women (OR_{women vs. men}=1.57, p<0.001), aged 25–29 (OR_{25–29 vs. 50–59}=1.65, p<0.001), participants with the lowest education level (OR _{uncompleted primary education vs. secondary}=1.47, p<0.001), participants self-classified in the lowest social class (OR _{lower vs. upper}=2.18, p=0.040); residents of urban communities (OR_{urban vs. rural residence community}=1.70, p<0.001), and participants from the central region of Slovenia (OR_{central vs. eastern}=1.32, p<0.001). Conclusions: Groups at highest risk for UNROD and IPA were successfully identified with the above-described methodology and presented to decision makers as evidence for public health policy. CHM surveys proved to be a good tool in developing effective healthy nutrition and physical activity intervention programmes.     

Vaccine hesitancy towards childhood immunisation amongst urban pregnant mothers in Malaysia

BackgroundVaccine hesitancy is a complex behaviour which involves various degrees of indecision about specific vaccines or vaccination uptake. Access to antenatal care had been associated with positive vaccine behavior.ObjectiveTo determine the prevalence of vaccine hesitancy towards childhood immunisation amongst urban pregnant mothers and the associated socio-demographic factors.MethodsA cross-sectional study was conducted among 1081 women who received antenatal care at a teaching hospital in Kuala Lumpur. Vaccine hesitancy was assessed using the Parent Attitudes about Childhood Vaccines (PACV) Survey in both English and validated Malay versions. The sociodemographic data of the mothers and their partners, source of vaccine information and reasons for hesitancy were analysed.ResultsEighty-six (8.0%) pregnant mothers were vaccine hesitant. Ethnicity, religion, number of children, educational level and employment status were significantly associated with vaccine hesitancy. Multivariable analysis showed that a low level of education was the most significant risk factor (p < 0.001), followed by religion (p = 0.03). Health professionals was the main source of information about vaccine. The non-vaccine hesitant women were more likely to seek information from health professionals, and health books and magazine. Fear of adverse side effects of vaccines was the predominant concern for all participants (58%) whilst fear of vaccination pain, preference for alternative medicine and lack of trust in the pharmaceutical industry were significant reasons given by the vaccine hesitant group. Partners’ ethnicity, a low educational level and a low income were significantly associated with vaccine hesitancy amongst pregnant mothers.ConclusionPrevalence of vaccine hesitancy amongst urban Malaysian pregnant women was relatively low. Muslim mothers are less likely to be vaccine hesitant. Educational level of mothers and their partners are the common determinant of vaccine hesitancy amongst antenatal mothers.     

Predictors of intention to vaccinate against COVID-19: Results of a nationwide survey

BackgroundPublic polling indicates that vaccine uptake will be suboptimal when COVID-19 vaccines become available. Formative research seeking an understanding of weak vaccination intentions is urgently needed.MethodsNationwide online survey of 804 U.S. English-speaking adults. Compensated participants were recruited from the U.S. through an internet survey panel of 2.5 million residents developed by a commercial survey firm. Recruitment was based on quota sampling to produce a U.S. Census-matched sample representative of the nation with regard to region of residence, sex, and age.ResultsCOVID-19 vaccination intentions were weak, with 14.8% of respondents being unlikely to get vaccinated and another 23.0% unsure. Intent to vaccinate was highest for men, older people, individuals who identified as white and non-Hispanic, the affluent and college-educated, Democrats, those who were married or partnered, people with pre-existing medical conditions, and those vaccinated against influenza during the 2019–2020 flu season.In a multiple linear regression, significant predictors of vaccination intent were general vaccine knowledge (β = 0.311, p < .001), rejection of vaccine conspiracies (β = ?0.117, p = .003), perceived severity of COVID-19 (β = 0.273, p < .001), influenza vaccine uptake (β = 0.178, p < .001), having ≥ 5 pre-existing conditions (β = 0.098, p = .003), being male (β = 0.119, p < .001), household income of ≥ $120,000 (β = 0.110, p = .004), identifying as a Democrat (β = 0.075, p < .029), and not relying upon social media for virus information (β = -0.090, p 〈0 0 2). Intent to vaccinate was lower for Fox News (57.3%) than CNN/MSNBC viewers (76.4%) (χ2 (1) = 12.68, p < .001). Political party differences in threat appraisals and vaccine conspiracy beliefs are described.ConclusionsDemographic characteristics, vaccine knowledge, perceived vulnerability to COVID-19, risk factors for COVID-19, and politics likely contribute to vaccination hesitancy.     

The effects of parent’s health literacy and health beliefs on vaccine hesitancy

Parental vaccine hesitancy is a key factor influencing children’s vaccination against infectious diseases such as the COVID-19. The current study aims to investigate how parent’s health literacy and health belief affect parental hesitancy toward the COVID-19 vaccination, and navigate effective measures to help parents make vaccination decision for children. A mixed-mode web survey was conducted among parents of children aged 3–11 years. Parental vaccine hesitancy, health literacy, and health beliefs were assessed. Parallel mediation model examined whether the association between parent's health literacy and vaccine hesitancy was mediated by health beliefs. In total, 11.3% of the 346 participants reported vaccine hesitancy. Hesitant parents were more likely to be he mother (Father: 4.5%; Mother: 12.9%) and with children having allergic issues (Allergic: 18.3%; Non-allergic: 9.8%). Meanwhile, parents with lower health literacy were more likely to show hesitancy towards vaccinating their children (β = −6.87, 95% CI = [−10.50, −3.11]). This relationship was partially mediated by more perceived barriers in vaccination (β = −2.53, 95%CI = [−4.09, −1.02]), but not other health beliefs. In other words, parents with better health literacy may perceive fewer barriers in making vaccination decision for their children, thus being less hesitant. Accordingly, healthcare professionals and policy makers could design education service to promote parents’ health literacy, and remove the perceived barriers as well as increase their confidence in following the COVID-19 vaccine guidance for children.     

Cognitive predictors of COVID-19 mitigation behaviors in vaccinated and unvaccinated general population members

BackgroundGiven the long-term threat posed by COVID-19, predictors of mitigation behaviors are critical to identify. Prior studies have found that cognitive factors are associated with some COVID-19 mitigation behaviors, but few studies employ representative samples and no prior studies have examined cognitive predictors of vaccination status. The purpose of the present study was to examine associations between cognitive variables (executive function, delay discounting, and future orientation) and COVID-19 mitigation behaviors (mask wearing, social distancing, hand hygiene and vaccination) in a population representative sample.MethodsA population representative sample of 2,002 adults completed validated measures of delay discounting, future orientation, and executive function. Participants also reported frequency of mitigation behaviors, vaccination status, and demographics.ResultsFuture orientation was associated with more mask wearing (β = 0.160, 95 % CI [0.090, 0.220], p < 0.001), social distancing (β = 0.150, 95 % CI [0.070, 0.240], p < 0.001), hand hygiene behaviors (β = 0.090, 95 % CI [0.000, 0.190], p = 0.054), and a higher likelihood of being fully vaccinated (OR = 0.80, 95 % CI [0.670, 0.970], p = 0.020). Lower delay discounting predicted more consistent mask wearing (β = −0.060, 95 % CI[−0.120, −0.010], p = 0.032) and being fully vaccinated (OR = 1.28, 95 % CI [1.13, 1.44], p < 0.001), while more symptoms of executive dysfunction predicted less mask wearing (β = −0.240, 95 % CI [−0.320, −0.150] p < 0.001) and hand hygiene (β = −0.220, 95 % CI [−0.320, −0.130], p < 0.001), but not vaccination status (OR = 0.96, 95 % CI [0.80, 1.16], p = 0.690) or social distancing behaviors (β = −0.080, 95 % CI [−0.180, 0.020], p = 0.097). Overall, social distancing was the least well-predicted outcome from cognitive factors, while mask wearing was most well-predicted. Vaccination status was not a significant moderator of these effects of cognitive predictors on mitigation behaviors.ConclusionsCognitive variables predict significant variability in mitigation behaviors. regardless of vaccination status. In particular, thinking about the future and discounting it less may encourage more consistent implementation of mitigating behaviors.     

Vaccine hesitancy among parents in a multi-ethnic country,Malaysia

BackgroundVaccine hesitancy is a threat in combating vaccine-preventable diseases. It has been studied extensively in the Western countries but not so among Asian countries.ObjectivesTo assess the test-retest reliability of the Parent Attitudes about Childhood Vaccines (PACV) questionnaire in Malay language; to determine the prevalence of vaccine hesitancy among parents and its associations with parents' socio-demographic characteristics.MethodsForward and backward translation of PACV in Malay language was carried out. The reliability of the Malay-PACV questionnaire was tested among parents with children. The same questionnaire was used to study vaccine hesitancy among parents in a tertiary hospital in Kuala Lumpur. Information pertaining to socio-demographic characteristics, sources of information regarding vaccination and vaccine hesitancy were collected. Associations between vaccine hesitancy with socio-demographic factors were tested using Multivariable Logistic Regression.ResultsThe Spearman correlation coefficient and Cronbach alpha for total PACV was 0.79 (p < 0.001) and 0.79 respectively. The intra-class correlation coefficients of the subscales ranged from 0.54 to 0.90 demonstrating fair to excellent reliability. A total of 63 (11.6%) parents were noted to be vaccine hesitant. In the univariate analyses, vaccine hesitancy was associated with unemployed parents, parents who were younger, had fewer children and non-Muslim. In the multivariate model, pregnant mothers expecting their first child were four times more likely to be vaccine hesitant compared to those who already had one or more children (aOR: 3.91, 95% CI: 1.74–8.79) and unemployed parents were also more likely to be vaccine hesitant (aOR: 1.97, 95% CI: 1.08–3.59). The internet (65.6%) was the main source of information on vaccination followed by brochures (56.9%).ConclusionThe Malay-PACV questionnaire is reliable to be used. The prevalence of vaccine hesitancy among the multi-ethnic Malaysians was comparable with other populations. Pregnant mothers expecting their first child and unemployed parents were found to be more vaccine hesitant.     

A validated modification of the vaccine hesitancy scale for childhood,influenza and HPV vaccines

IntroductionVaccine hesitancy contributes to outbreaks of preventable disease worldwide. The Vaccine Hesitancy Scale (VHS), developed by the international WHO SAGE Working Group, has been validated previously for measuring hesitancy towards childhood vaccines; some psychometric properties were suboptimal.MethodsWe collected data using large, nationally-representative samples of parents in the U.S. We adapted the VHS items, and additional hesitancy items, to assess hesitancy towards influenza and HPV vaccines in addition to routine childhood vaccines. We then used exploratory and confirmatory factor analysis to identify latent constructs and create modified scales for childhood (VHS-child), influenza (VHS-flu) and HPV (VHS-HPV) vaccines with improved psychometric properties. Finally, we compared hesitancy scores on the VHS-child, VHS-flu, and VHS-HPV, to self-reported receipt of each vaccine category, and compared subscale scores to assess whether drivers of hesitancy differed by vaccine category.Results2052 parents of children <18 years old completed the VHS-child and VHS-flu while 2020 parents of adolescents completed the VHS-HPV. A two-factor structure of ‘risks’ and a ‘lack of confidence’ was found for each vaccine category. Slight modifications to the VHS improved psychometric properties. Hesitancy was strongly associated with vaccine receipt: e.g., 76% of parents not hesitant towards influenza vaccine had vaccinated their child the past season, versus 9% of hesitant parents (p < 0.0001). Subscale scores also differed significantly between vaccines: lack of confidence was greater towards influenza (Median (IQR): 2.0 (1.2, 3.3)) and HPV (2.0 (1.3, 3.0)) vaccines than childhood (1.2 (1.0, 1.8), p < 0.0001 for both) vaccines; perceived risks of HPV vaccines (2.7 (1.7, 3.7)) were greater than for childhood vaccines (2.0 (1.3, 3.0), p < 0.0001).ConclusionsOur modified VHS scales perform well psychometrically and allow for consistent measurement of the extent and reasons for hesitancy between vaccine categories. We suggest that future work use these scales to examine hesitancy towards other vaccines and to monitor hesitancy over time.     

Latinx Immigrant Mothers’ Perceived Self-Efficacy and Intentions Regarding Human Papillomavirus Vaccination of Their Daughters

ObjectiveRacial and ethnic disparities persist in cervical cancer cases, 90% of which are caused by the human papillomavirus (HPV). Suboptimal vaccine uptake is problematic, particularly among Latinx women, who have the highest cervical cancer incidence compared with other racial/ethnic groups. We examined the association of self-efficacy and HPV vaccination intention among Latinx immigrant mothers of unvaccinated 9- to 12-year-old girls.MethodsAn interviewer-administered survey assessed baseline sociodemographic information, knowledge and perceived risk of cervical cancer and HPV, self-efficacy, and intention to vaccinate among 313 Latinx immigrant mothers in Alabama from 2013 to 2017 before the implementation of an intervention to promote HPV vaccination.ResultsParticipants were, on average, 35 years old, with 9 years of education, and had lived in the United States for 12 years. Mothers who perceived their daughters were at risk of HPV infection were more likely to be vaccine intent than their hesitant counterparts (p < .001). Vaccine hesitancy was more common in those with lower education, low HPV and cervical cancer knowledge, and lower perceived self-efficacy scores (p < .001). Self-efficacy was associated with vaccine intention when controlling for other variables (p < .001). The only variable associated with self-efficacy was HPV awareness (p = .001).ConclusionsPrograms promoting HPV vaccination among Latinx immigrants should include educational components regarding risks of HPV infection and cervical cancers in addition to information regarding access to vaccination services. Knowledge of risks and access may heighten perceptions of self-efficacy and improve vaccine uptake among this population.     

Patterns and influencing factors of COVID-19 vaccination willingness among college students in China

BackgroundVaccination is an important preventive measure against the coronavirus disease 19 (COVID-19) pandemic. We aimed to examine the willingness to vaccination and influencing factors among college students in China.MethodsFrom March 18 to April 26, 2021, we conducted a cross-sectional online survey among college students from 30 universities in Wuhan, Hubei Province, China. The survey was composed of the sociodemographic information, psychological status, experience during pandemic, the willingness of vaccination and related information. Students’ attitudes towards vaccination were classified as ‘vaccine acceptance’, ‘vaccine hesitancy’, and ‘vaccine resistance’. Multinomial logistic regression analyses were performed to identify the influencing factors associated with vaccine hesitancy and resistance.ResultsAmong 23,143 students who completed the survey, a total of 22,660 participants were included in the final analysis with an effective rate of 97.9% after excluding invalid questionnaires. A total of 60.6% of participants would be willing to receive COVID-19 vaccine, 33.4% were hesitant to vaccination, and 6.0% were resistant to vaccination. Social media platforms and government agencies were the main sources of information vaccination. Worry about the efficacy and adverse effects of vaccine were the top two common reason of vaccine hesitancy and resistance. Multiple multinomial logistic regression analysis identified that participants who worried about the adverse effects of vaccination were more likely to be vaccine hesitancy (aOR = 2.44, 95% CI = 2.30, 2.58) and resistance (aOR = 2.71, 95% CI = 2.40, 3.05).ConclusionMore than half of college students are willing to receive the COVID-19 vaccine, whereas nearly one-third college students are still hesitant or resistant. It is crucial to provide sufficient and scientific information on the efficacy and safety of vaccine through social media and government agencies platforms to promote vaccine progress against COVID-19 and control the pandemic in China.     

The determinants of vaccine hesitancy in China: A cross-sectional study following the Changchun Changsheng vaccine incident

IntroductionVaccine hesitancy is cited as one of the top threats to global health. The Changchun Changsheng Biotechnology Company was found to have violated good manufacturing practices in July 2018, leading to widespread distribution of sub-potent vaccines in China. We estimated the prevalence and determinants of vaccine hesitancy following the Changchun Changsheng vaccine incident (CCVI).MethodsWe conducted a cross-sectional survey in China in January 2019, and 2,124 caregivers of children < 6 years old completed self-administered questionnaires. Multinomial logistic regression was used to assess the determinants of vaccine hesitancy; the potential determinants included demographics, socioeconomic status, vaccine confidence, and knowledge of the CCVI. Adjusted Odds Ratios (AORs) and 95% confidence intervals (CI) are reported.ResultsAround 89% of caregivers had heard of the CCVI. Although 83% and 88% of caregivers agreed that vaccines are safe and effective, respectively, 60% expressed some hesitancy about vaccination. Of those hesitant, 26% vaccinated their children at times with doubts, 31% delayed vaccination and 3% refused specific vaccines. Multinomial regression analysis showed that confidence in vaccine safety was associated with a reduced odds of doubts on vaccination (AOR = 0.64; 95%CI = 0.44–0.94), whereas caregivers who had heard of the CCVI had a significantly higher odds of doubts on vaccination (AOR = 1.61; 95%CI = 1.05–2.45). Confidence in the vaccine delivery system and government were associated with a lower odds of vaccine hesitancy. Caregivers with higher education and Buddhism or other religions were significantly more hesitant to vaccinate their children.ConclusionVaccine hesitancy was prevalent following the CCVI. Over half the caregivers either accepted childhood vaccination with doubts or delayed vaccines; only a small number were active refusers. Our findings highlight the importance of addressing vaccine hesitancy, especially following vaccine incidents. Tailored communications are needed to reduce vaccine hesitancy, especially among the highly educated and Buddhist caregivers.     

The Role of Social Support in Machismo and Acceptance of Violence Among Adolescents in Europe: Lights4Violence Baseline Results

PurposeTo analyze the potential association between social support, experiences of violence, and sociodemographic characteristics of adolescents and the likelihood of acceptance of violence and machismo in different European countries.MethodsCross-sectional design. We recruited 1,555 participants ages 13–16 from secondary schools in Alicante (Spain), Rome (Italy), Iasi (Romania), Matosinhos (Portugal), Poznan (Poland), and Cardiff (UK). We used linear regression models to identify how social support from teachers and parents, experiences of violence—dating violence, bullying, cyberbullying, abuse in childhood—and sociodemographic characteristics were associated with violent thinking, specifically: machismo and acceptance of violence. The analysis was stratified by sex.ResultsAcceptance of violence was higher for those who had lower perceived social support from parents (β_girls = ?154, p < .001; β_boys = ?.114, p = .019) for both sexes. Perpetration of bullying and/or cyberbullying was associated with higher scores for machismo and acceptance of violence for both sexes (β_girls = .067, p = .035; β_boys = .225, p < .001; (β_girls = .118, p < .001; β_boys = .210, p < .001). Being the victim of dating violence, having suffered physical and/or sexual abuse in childhood, and lower perceived social support from teachers were associated with higher scores for both machismo and acceptance of violence. These associations differed between girls and boys.ConclusionsMachismo and acceptance of violence are widely present amongst adolescents in different European countries. Our results suggest the importance of providing educational/psycho-educational interventions with boys and girls to prevent these attitudes and, in turn, prevent interpersonal violence, including bullying and dating violence.     

Beliefs about causes of autism and vaccine hesitancy among parents of children with autism spectrum disorder

Vaccine hesitancy may be more common among parents of children with autism spectrum disorder (ASD). We examined factors associated with ASD-specific vaccine hesitancy among caregivers of children with ASD who participated in the SPARK study (Simons Foundation Powering Autism Research for Knowledge). 225 participants completed an online survey containing the Parent Attitudes About Childhood Vaccines (PACV) questionnaire (measure of vaccine hesitancy) and the Illness Perception Questionnaire revised for parents of children with ASD (IPQ-R-ASD; measure of parents’ views about ASD). 65 participants (28.8%) were vaccine hesitant (PACV score ≥ 50); children of vaccine-hesitant parents (VHPs) were less likely to be first born (n = 27, 41.5%), had greater ASD-symptom severity (mean Social Communication Questionnaire score = 23.9, SD = 6.9), and were more likely to have experienced developmental regression (n = 27, 50.9%) or plateau (n = 37, 69.8%). Compared to non-hesitant parents, VHPs significantly more often endorsed accident/injury, deterioration of the child’s immune system, diet, environmental pollution, general stress, parents’ negative views, parents’ behaviors/decisions, parents’ emotional state, and vaccines as causes for ASD. VHPs also had higher scores on the Personal Control, Treatment Control, Illness Coherence, and Emotional Representations subscales of the IPQ-R than did non-hesitant parents. In the final model, ASD-related vaccine hesitancy was significantly associated with higher scores on the Emotional Representations subscale (OR = 1.13, p = 0.10), agreement with deterioration of the child’s immunity as a cause of ASD (OR = 12.47, p < 0.001), the child not having achieved fluent speech (OR = 2.67, p = 0.17), and the child experiencing a developmental plateau (OR = 3.89, p = 0.002). Findings suggest that a combination of child functioning and developmental history, as well as parents’ negative views about and their sense of control over ASD, influence vaccine hesitancy among parents of children with ASD.     

A longitudinal assessment of variability in COVID-19 vaccine hesitancy and psychosocial correlates in a national United States sample

Recent evidence suggests that COVID-19 vaccine hesitancy is not static. In order to develop effective vaccine uptake interventions, we need to understand the extent to which vaccine hesitancy fluctuates and identify factors associated with both between- and within-person differences in vaccine hesitancy. The goals of the current study were to assess the extent to which COVID-19 vaccine hesitancy varied at an individual level across time and to determine whether disgust sensitivity and germ aversion were associated with between- and within-person differences in COVID-19 vaccine hesitancy. A national sample of U.S. adults (N = 1025; 516 woman; M_age = 46.34 years, SD_age = 16.56, range: 18 to 85 years; 72.6 % White) completed six weekly online surveys (March 20 – May 3, 2020). Between-person mean COVID-19 vaccine hesitancy rates were relatively stable across the six-week period (range: 38–42 %). However, there was considerable within-person variability in COVID-19 vaccine hesitancy. Approximately, 40 % of the sample changed their vaccine hesitancy at least once during the six weeks. There was a significant between-person effect for disgust sensitivity, such that greater disgust sensitivity was associated with a lower likelihood of COVID-19 vaccine hesitance. There was also a significant within-person effect for germ aversion. Participants who experienced greater germ aversion for a given week relative to their own six week average were less likely to be COVID-19 vaccine hesitant that week relative to their own six-week average. This study provides important information on rapidly changing individual variability in COVID-19 vaccine hesitancy on a weekly basis, which should be taken into consideration with any efforts to decrease vaccine hesitancy and increase vaccine uptake. Further, these findings identify-two psychological factors (disgust sensitivity and germ aversion) with malleable components that could be leveraged in developing vaccine uptake interventions.
