[PMID: 38316954 PMCID: PMC11220043 DOI: 10.1038/s41431-024-01547-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 11/12/2023] [Accepted: 01/18/2024] [Indexed: 02/07/2024] Open
Abstract
The use of genomic data in research and genomic information in clinical care is increasing as technologies advance and sequencing costs decrease. Using Rogers' Diffusion of Innovation (DOI) theory as a framework we reviewed recent literature examining publics' current knowledge of, attitude to, and motivation towards health-related genomics in clinical and research settings. The population of interest was described as 'publics' to denote the heterogeneity of 'the public'. Eligible studies were published in English between 2016-2022. We retrieved 1657 records, with 278 full-text reviewed against the eligibility criteria and concept definitions. In total, 99 articles were included in the review and descriptive numerical summaries were collated. Knowledge literature was categorized using deductive thematic analysis. For attitude and motivation, literature was coded using an analytic framework developed by the authors. There was wide variability in concept definition and measurement across studies. Overall, there was general positivity about genomics, with high awareness but little familiarity or factual knowledge. Publics had high expectations of genomics and perceived that it could provide them with information for their future. Only a few key attitudes were found to be important as motivators or barriers for participation in genomics; these were related to personal and clinical utility of the information. Context was often missing from studies, decreasing the utility of findings for implementation or public engagement. Future research would benefit by using theory-driven approaches to assess relevant publics' knowledge and attitudes of specific contexts or applications to support genomic implementation and informed decision-making.

Melchior F, Beyreuther K, Teichmann B. Translation, validation, and comparison of genetic knowledge scales in Greek and German. Front Genet 2024; 15:1350308. [PMID: 38812970 PMCID: PMC11133520 DOI: 10.3389/fgene.2024.1350308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 04/29/2024] [Indexed: 05/31/2024] Open
Abstract
Introduction : Advances in biosciences have significantly expanded our knowledge and capabilities in medicine and technology. Genetic tests can now predict hereditary predisposition or susceptibility to diseases, while gene-editing tools like CRISPR/Cas enable easy repair of disease genes in both somatic and germline cells, ensuring permanent genome correction. Despite these advancements, there is a shortage of valid instruments for studying the knowledge about these technologies. To fill this gap, our study aims to translate and validate various scales to effectively measure the public's knowledge of genetics. Methods: A convenience sample of N = 567 (Germany n = 317, Greece n = 250) participants completed a Google Forms questionnaire between December 2022 and June 2023, which included the General Knowledge of Genes and Heredity (GKGH), Knowledge about Gene-Environment Interaction (KGEI), and Knowledge of Modern Genetics and Genomics (KMGG) questionnaires. Analyses included internal consistency, structural validity, construct validity, and retest reliability with a subset of n = 72 (DE) and n = 50 (GR). Correlation analyses and group differences were evaluated for gender, education, religiosity, age, prior experience with genetic testing, and preferences toward potential providers of genetic testing. This study used the STROBE checklist for reporting. Results: The GKGH exhibited low values in internal consistency and item analysis, along with a ceiling effect within the German group. However, it demonstrated good values in retest and construct validity. In the Greek group, all properties were highly satisfactory. The KMGG consistently displayed excellent properties across all analyses, whereas the KGEI only showed convincing results in construct validity and item analysis. Discussion: The GKGH and KMGG demonstrated strong psychometric properties with varying difficulty levels dependent on the sample, with the German sample demonstrating a notably higher understanding of genetic technologies. Despite displaying acceptable properties, the KGEI fell short of measuring what its title suggests. Participants' level of education showed a significant correlation with knowledge of genetic technologies, and only in the Greek sample did experiences with genetic tests influence knowledge. Preferences regarding availability of genetic testing are comparable between the two countries, with variations influenced by factors such as age, gender and religiosity.

Knowledge and attitudes regarding genetic testing among Jordanians: An approach towards genomic medicine. Saudi J Biol Sci 2021; 28:3989-3999. [PMID: 34220256 PMCID: PMC8241592 DOI: 10.1016/j.sjbs.2021.04.004] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 03/21/2021] [Accepted: 04/04/2021] [Indexed: 12/23/2022] Open
Abstract
Background The twenty first century can be called the genomic era referring to the rapid development of genetics, and the beginning of genomic medicine. An initial step towards genomic medicine is to evaluate the knowledge and attitude towards genetic testing among different populations. The aims of this study were to assess the genetic knowledge and attitude towards genetic testing among the Jordanian population and patients with immune diseases. In addition, we evaluated the association between knowledge, attitude and several demographic factors of the population. Methods This study was performed using an online questionnaire that was distributed to respondents from different regions of Jordan. Results A total of 1149 participants were recruited from the Jordanian population. Overall factual genetic knowledge of the participants was good (65.4%), with education level, working or studying in a health-related field and household average monthly income being significant predictors of factual knowledge scores (P = 0.03, P < 0.001 and P < 0.001, respectively). However, factual knowledge results revealed that scores of questions related to diseases were significantly higher than scores of gene-related scientific facts (P < 0.01). Participants of our study reported to have low perceived knowledge on medical uses (39.5%) and social consequences (23.9%) of genetic testing. Regarding the participants’ attitudes, favorable attitudes towards genetic testing were prevailing (91.5%). Favorable attitudes were more prominent among higher educated participants, and participants with higher scores of factual knowledge. Conclusion Despite the fact that our Jordanian-based study revealed a good level of genetic knowledge as well as a favorable attitude towards genetic testing, we realized an imbalance of knowledge between gene-related scientific facts and disease-related concepts as well as between factual and perceived genetic knowledge, which indicates the necessity of increasing the awareness about genetic testing in order to ensure that individuals can take informed decisions that help in the employment of personalized medicine.

Abstract
Background This study aimed to explore the parental genetic knowledge and attitudes toward childhood genetic testing of the inherited eye diseases (IEDs) in China. Methods This is a cross‐sectional survey. All parents were assessed via self‐administered questionnaires. Data were collected through the Internet at the pediatric eye clinics in a tertiary referral eye hospital. Results In total, 359 parents were included into this survey. The proportion of correctly answered the factual genetic knowledge questionnaire ranged from 35.7% to 81.3%, which is positively correlated to the educational levels and household per capita income. The attitudes toward childhood IEDs genetic testing appeared to be consistent. More factual genetic knowledge was predictive for a favorable attitude toward genetic testing. Han Chinese might be slightly more likely to have a favorable attitude. Interestingly, the higher educational levels and lower monthly incomes were predictive factors for a reserved attitude toward genetic testing. The families without history of IEDs were more inclined to remain a reserved attitude than those with family history of IEDs. Conclusion This study illustrated that more factual genetic knowledge was considered as an indicator for the favorable attitudes. Therefore, the effective strategies should be taken to provide the correct knowledge of genetics and genetic testing to parents, especially those who need to make an informed decision thereon to undertake childhood genetic testing.
