COVID-19-Related Knowledge and Anxiety Response among Physical Education Teachers during Practical In-Person Lessons: Effects of Potential Moderators.

The COVID-19 pandemic has resulted in heightened anxiety levels among teachers, especially regarding PE teachers who are required to engage students in practical in-person or contact teaching lessons. Previous research showed that these levels of anxiety among PE teachers appeared to be explained by the interplay between COVID-19 knowledge, workplace safety perception, and educational qualification. This study assessed the relationship between COVID-19-related knowledge and anxiety response among PE teachers during such practical lessons while moderating the effects of workplace safety perception and educational qualification within the relationship. The study conveniently recruited 160 PE teachers to solicit responses through both online and printed questionnaires. Using correlation and linear regression analyses, the study revealed a significant negative relationship between COVID-19-related knowledge and anxiety response among PE teachers. The educational qualification of PE teachers did not significantly moderate the association between COVID-19-related knowledge and anxiety response. Workplace safety perception significantly moderated the association between COVID-19-related knowledge and anxiety response among PE teachers. The findings remind educational authorities about the essence of creating a positive and safe working environment conducive to academic work. Achieving this goal requires the provision of adequate COVID-19 management logistics (e.g., personal protective equipment, hand sanitizers) by educational authorities for PE teachers to maintain safety practices and optimal learning conditions.

Using instrumental variables to estimate the attributable fraction.

In order to design efficient interventions aimed to improve public health, policy makers need to be provided with reliable information of the health burden of different risk factors. For this purpose, we are interested in the proportion of cases that could be prevented had some harmful exposure been eliminated from the population, i.e. the attributable fraction. The attributable fraction is a causal measure; thus, to estimate the attributable fraction from observational data, we have to make appropriate adjustment for confounding. However, some confounders may be unobserved, or even unknown to the investigator. A possible solution to this problem is to use instrumental variable analysis. In this work, we present how the attributable fraction can be estimated with instrumental variable methods based on the two-stage estimator or the G-estimator. One situation when the problem of unmeasuredconfounding may be particularly severe is when assessing the effect of low educational qualifications on coronary heart disease. By using Mendelian randomization, a special case of instrumental variable analysis, it has been claimed that low educational qualifications is a causal risk factor for coronary heart disease. We use Mendelian randomization to estimate the causal risk ratio and causal odds ratio of low educational qualifications as a risk factor for coronary heart disease with data from the UK Biobank. We compare the two-stage and G-estimator as well as the attributable fraction based on the two estimators. The plausibility of drawing causal conclusion in this analysis is thoroughly discussed and alternative genetic instrumental variables are tested.

Correlates of Adult Vocabulary Task Performance: Findings from a British Cohort.

This study explored a longitudinal data set of 4361 adults (2119 males and 2239 females) to examine factors that influence adult vocabulary task performance. Data were collected at birth, in childhood (age 10 years), during teenage years (age 16 years), and in adulthood (ages 30, 34, and 42 years) to examine the effects of family social status, childhood cognitive ability, teenager locus of control, psychological distress, educational qualifications, and occupational prestige in adulthood on an adult vocabulary task-an index of crystallized intelligence. Structural equation modeling showed that childhood cognitive ability, teenager locus of control, education, and occupation were all significant and direct predictors of adult vocabulary task performance. Parental social status affected the outcome variable mediated through educational qualifications. The strongest predictor of adult vocabulary task performance was childhood cognitive ability, followed by educational qualifications and locus of control. Finally, limitations were acknowledged.

Teenage locus of control, psychological distress, educational qualifications and occupational prestige as well as gender as independent predictors of adult binge drinking.

Our objective was to investigate various psychological and socio-demographic factors in childhood and adulthood that relate to alcohol intake and binge drinking at age 42 years. Data were drawn from the 1970 British Cohort Study (BCS70), a prospective longitudinal study monitoring the development of babies born in 1970, with nine follow-ups. The analytic sample comprised 5190 cohort members with complete data on parental social class at birth, cognitive ability at age 10 years, locus of control at age 16 years, psychological distress at age 30 years, educational qualifications obtained at age 34 years, and current occupation and alcohol consumption at age 42 years. Results showed that sex (male), lower parental social class, adolescent external locus of control, psychological distress, lower scores on childhood intelligence, lower educational qualifications, and less-professional occupations were all significantly and positively associated with binge drinking in adulthood. Hierarchical logistic regression analyses showed that sex (OR = 0.52, CI: 0.44-0.60, p < .001), parental social class (OR = 0.67, CI: 0.50-0.92 to OR = 0.49, CI: 0.31-0.57, p < .05 to p < .01), locus of control beliefs (OR = 0.90, CI: 0.84-0.96, p < .01), adult psychological distress (OR = 1.28, CI: 1.04-1.58, p < .05), educational qualifications (OR = 0.70, CI: 0.53-0.92 to OR = 0.39, CI: 0.25-0.61, p < .05 to p < .001), and occupational prestige (OR = 0.59, CI: 0.38-0.95 to OR = 0.36, CI: 0.20-0.65, p < .05 to p < .01) were all significant and independent predictors of adult binge drinking. Both psychological and socio-demographic factors associated with adult excessive alcohol consumption. Adolescent locus of control beliefs had a significant effect on adult binge drinking 26 years later.

Childhood Cognitive Ability Predicts Adult Financial Well-Being.

This study set out to investigate to what extent childhood cognitive ability, along with personality traits, education and occupational status, as well as marital status influence adult financial success. Data were drawn from a large, prospective birth cohort in the UK, the National Child Development Study (NCDS). The analytic sample was comprised of 4537 cohort members with data on parental social class (at birth), cognitive ability (at age 11), educational qualifications (at age 33), personality traits (at age 50), current marital status and occupational prestige, and salary/wage earning level (all measured at age 54). Correlational results showed that parental social class, childhood cognitive ability, traits extraversion, emotional stability, conscientiousness, and openness, being married positively, being divorced or separated negatively, education and occupation as well as gender were all significantly associated with adult earning ability (p < 0.05 to p < 0.001). Effect sizes for the relationship between intelligence and income was moderate. Results of a multiple regression analysis showed that childhood cognitive ability, traits conscientiousness and openness, educational qualifications and occupational prestige were significant and independent predictors of adult earning ability accounting for 30% of the total variance. There was also a gender effect on the outcome variable. Numerous limitations are noted.
