The Hong Kong Early Child Development Scale-3: a validation study

The Hong Kong Early Child Development Scale (HKECDS) is a tool for assessing holistic early child development in preschoolers aged from three to six years. The original version of the scale, HKECDS, was updated in 2019 (HKECDS-2) to reflect the contemporary context and local curricular expectations. Children (n = 144) from three kindergartens in Hong Kong completed the HKECDS-2 in individual sessions. Rasch model analysis and expert discussions resulted in a short version of the scale (HKECDS-3) with 50 items in nine domains. The domains are Personal and self-care (4 items), Language development (7 items), Pre-academic learning (10 items), Cognitive development (6 items), Gross motor (4 items), Fine motor (2 items), Health and safety (5 items), Moral development (6 items), and Society and environment (6 items). There were significant correlations between findings from the updated version of the tool, HKECDS-3 and the HKECDS-2 (long form), and older children had significantly higher scores than younger children

Acceptance of the COVID-19 vaccine based on the health belief model: A population-based survey in Hong Kong

BACKGROUND: Vaccines for COVID-19 are anticipated to be available by 2021. Vaccine uptake rate is a crucial determinant for herd immunity. We examined factors associated with acceptance of vaccine based on (1). constructs of the Health Belief Model (HBM), (2). trust in the healthcare system, new vaccine platforms and manufacturers, and (3). self-reported health outcomes. METHODS: A population-based, random telephone survey was performed during the peak of the third wave of COVID-19 outbreak (27/07/2020 to 27/08/2020) in Hong Kong. All adults aged ≥ 18 years were eligible. The survey included sociodemographic details; self-report health conditions; trust scales; and self-reported health outcomes. Multivariable regression analyses were applied to examine independent associations. The primary outcome is the acceptance of the COVID-19 vaccine.RESULTS: We conducted 1200 successful telephone interviews (response rate 55%). The overall vaccine acceptance rate after adjustment for population distribution was 37.2% (95% C.I. 34.5–39.9%). The projected acceptance rates exhibited a “J-shaped” pattern with age, with higher rates among young adults (18–24 years), then increased linearly with age. Multivariable regression analyses revealed that perceived severity, perceived benefits of the vaccine, cues to action, self-reported health outcomes, and trust in healthcare system or vaccine manufacturers were positive correlates of acceptance; whilst perceived access barriers and harm were negative correlates. Remarkably, perceived susceptibility to infection carried no significant association, whereas recommendation from Government (aOR = 10.2, 95% C.I. 6.54 to 15.9, p < 0.001) was as the strongest driving factor for acceptance. Other key obstacles of acceptance included lack of confidence on newer vaccine platforms (43.4%) and manufacturers without track record (52.2%), which are of particular relevance to the current context.CONCLUSIONS: Governmental recommendation is an important driver, whereas perceived susceptibility is not associated with acceptance of COVID-19 vaccine. These HBM constructs and independent predictors inform evidence-based formulation and implementation of vaccination strategies
