Educational tools support informed decision-making for genetic carrier screening in a heterogenic Israeli population

Reproductive genetic carrier screening (RGCS) aims to provide couples with information to make informed decisions. Since 2013, the Israeli Carrier Screening Program has been offered routinely and free of charge to all Israelis of reproductive age, personalized based on religion, ethnicity, and village/tribe where a disorder is frequent. This study evaluated the impact of two educational tools on an informed choice on RGCS uptake and satisfaction with counselling within a heterogeneous population in northern Israel. Participants from diverse sociodemographic population groups were randomly assigned to watch an animated film, read a booklet conveying the same information, or receive no information before counselling for RGCS, and asked to complete pre- and post-counselling questionnaires. A higher informed-decision rate was demonstrated in the film (n=93/141, 66%) and booklet (n=88/131, 67%) groups vs. the non-intervention group (n=62/143, 43%) (P<0.001), assessed by the Multidimensional Measure of Informed Choice. Multivariate logistic regression analysis revealed that allocation to an intervention group, Jewish ethnicity and higher education level, best predicted informed choice. Most participants expressed high levels of satisfaction with the counselling process, regardless of group assignment. While only a minority of participants reported seeking information prior to visiting the clinic, the pre-counselling information interventions were well accepted. Pre-counselling self-learning educational tools should be promoted, easily available, and adjusted linguistically and culturally to targeted populations, to avoid unwanted "automatic" compliance of tested individuals and maximize the potential of informed decision-making. Our study can be applied to other countries where majority and minority ethnic groups access genetic services.

Predictors of parents' infant vaccination decisions: A concept derivation

The myths surrounding coronavirus disease 2019 (COVID-19) vaccines have prompted scientists to refocus their attention on vaccine hesitancy, which is fuelled by the spread of misinformation. The scientific investigation of behavioural concepts relating to vaccine hesitancy can be enhanced by the examination of behavioural concepts from the field of consumer sciences. South African consumer scientists study personal decisions that contribute to individuals' well-being, including the decisions to prevent ill health. Current data on the predictors of vaccination decisions do not incorporate consumer science constructs imperative in decision-making, which could provide fresh insights in addressing vaccine hesitancy. This study aimed to investigate and illustrate the analogy between concepts of the Health Belief Model (HBM) as parent model, and consumer behaviour that could affect parents' infant vaccination decisions, by applying a concept derivation approach. The HBM was analysed within the context of public health, including literature from consumers' vaccination decisions, medical decisions, paediatrics, vaccinology, virology and nursing. Through a qualitative, theory derivation strategy, six main concepts of the HBM were redefined to consumer sciences, using four iterative concept derivation steps. Concept derivation resulted in consumer behaviour concepts that could be possible predictors of parents' infant vaccination decisions, including consumers' values; risk perception; consideration of immediate and future consequences; self-efficacy; cues to action; demographics; personal information and knowledge. These predictors could be a starting point for a context- and product-specific consumer primary preventive healthcare decisions model. Our findings highlight the opportunities for interdisciplinary collaboration in investigating consumer primary healthcare-related behaviour.

CONTRIBUTION

This study introduced interfaces between consumer science and health science literature. Through interdisciplinary collaboration, a better understanding of influences to promote primary preventive healthcare can be achieved.
