Public Understanding and Opinions regarding Genetic Research on Alzheimer's Disease

Attitudes, Motivations, and Barriers to Pre-Symptomatic Alzheimer's Disease Screening: Development and Validation of the 'Perceptions regarding pRE-symptomatic Alzheimer's Disease Screening' (PRE-ADS) Questionnaire

BACKGROUND

Pre-symptomatic screening methods for detecting a higher risk of Alzheimer's disease (AD) are gaining popularity; thus, more people are seeking these tests. However, to date, not much is known about the attitudes toward pre-symptomatic AD screening.

OBJECTIVE

The goal of this study is to examine the psychometric properties of a tool for assessing the attitudes, barriers, and motivations to pre-symptomatic AD screening.

METHODS

This is a cross-sectional study performed on 208 Greek participants (189 students and 19 caregivers) provided with an online questionnaire. Psychometric properties were assessed through the examination of its construct validity (principal component analysis) and internal consistency.

RESULTS

Exploratory factor analysis revealed the presence of four factors. The first factor is labeled as "Perceived harms of testing" (10 items), the second "Acceptance of testing" (5 items), the third "Perceived benefits of testing" (6 items), and the fourth factor "Need for knowledge" (4 items). The reliability (internal consistency) of each factor separately was acceptable to good (0.70-0.87) while the internal consistency of the overall questionnaire (25 items) was good (Cronbach's α=0.82).

CONCLUSION

PRE-ADS is a valid questionnaire that might help in the research of peoples' attitudes related to the pros and cons of pre-symptomatic screening for AD, and the development of effective counseling programs and prevention strategies. However, future research is required in the target population.

Remote Teaching Due to COVID-19: An Exploration of Its Effectiveness and Issues

Universities have quickly shifted to remote learning due to the COVID-19 pandemic. This study compared two versions-emergency remote teaching (ERT) and conventional face-to-face class (FFC)-of a course design based on the instructional design ARCS model for effectiveness and issues. The current study comprised 46 third-year nursing students who attended an FFC course in 2019, and 56 third-year students who took the ERT version in 2020. Students' self-rated goal attainment and knowledge of genetics scores were compared before and after taking the courses. Scores between the two class types were compared using the Wilcoxon rank sum test. The students' worksheets were evaluated using keyword frequency and content analyses. Both classes achieved their goals satisfactorily, and this study confirmed that for this course, ERT was as effective as FFC. A comparison of the increase in domain goal attainment scores per student showed that only the psychomotor domain item, "I can fully explain human diversity using genomic information", was significantly different, as it was significantly higher for ERT (p = 0.003). This higher item in the ERT group suggests that ERT can pose a lack of practice caution in acquiring nursing skills.

Genetics education program to help public health nurses improve their knowledge and enhance communities' genetic literacy: a pilot study

BACKGROUND

As human genetics knowledge develops, public genetic literacy needs to be increased, though the educational capacity for this purpose has not yet been fully developed. Under this circumstance, the daily work of public health nurses can be viewed as an opportunity to enhance public genetic literacy. However, in Japan, there is not only a lack of public knowledge of human genomics but also a lack of public health nurses' recognition about genomic literacy. A short-term education program was implemented as a pilot study. This study aimed to examine the effectiveness of the program to support public health nurses' activity aimed at promoting health services-related genetic literacy.

METHODS

The genetics education program was implemented in December 2019, in Kagoshima, Japan. Twenty-three public health nurses cooperated with the research. The program was composed of a case study on consultation, a lecture on hereditary diseases, and a discussion on the role of public health nurses. Familial hypercholesterolemia was used as the topic of the case study. We evaluated scores for cognition, affect, and psychomotor characteristics related to their learning goals before and after the program using Wilcoxon signed-rank tests. Answers in the consultation were qualitatively analyzed.

RESULTS

The mean cognitive score, capturing provision of explanations of hereditary disease, was 6.3 before the program but increased significantly to 9.3 after the program (p < 0.001). For the affective score, the goal of which was deepening interest in human genetics, the mean score increased significantly from 8.5 before to 11.0 after (p < 0.001). For the psychomotor score, addressing the need for genetic consultation, the mean score increased significantly from 4.4 before to 8.1 after (p < 0.001). Prominent themes extracted from descriptions on the worksheet post training included, "providing advice and accurate information on genetic disorders" and "referral to a specialized organization."

CONCLUSIONS

Our findings indicated that this education program helps public health nurses be positively involved in human genetic disorders. Thus, they may connect to their local community to provide accurate genetics knowledge and advice for health management and promoting genetic literacy.

Alzheimer Disease Worries, Fears, and Stigma and Their Relationship to Genetic and Interventional Research Engagement

BACKGROUND

Alzheimer disease (AD) research increasingly requires healthy individuals willing to undergo genetic testing.

OBJECTIVE

This study seeks to: (1) describe older adults' beliefs about AD genetic testing, worry about AD, and fear of AD stigma, and (2) explore how these constructs relate to research participation.

METHODS

Surveys were sent to participants active in AD-observational research and those that were not. Three measures of research participation were explored: (1) being a current research participant, (2) self-report of clinical trial participation, and (3) expressing genetic registry interest.

RESULTS

The majority of the 502 respondents perceived greater benefit than the risk associated with AD genetic testing. AD worry and perceptions of AD stigma were low. Higher levels of AD worry and lower perceptions of AD stigma were associated with being a current AD research volunteer. AD worry and stigma were unrelated to clinical trial participation or genetic registry interest; these research participation measures were associated with AD genetic testing benefit.

CONCLUSIONS

Beliefs about AD genetic testing, AD worry, and AD stigma are related to research participation, but relationships vary based on the research participation investigated. Future work should identify how these findings can inform outreach and recruitment efforts.
