Background: Positive maternal mental health during the perinatal period contributes to general well-being and positive emotional bonds with the child, encouraging an optimal developmental trajectory. Online interventions to enhance maternal well-being and develop coping skills, such as meditation-based interventions, can be a low-cost way to improve mother and child outcomes. However, this depends on end-user engagement. To date, there is limited evidence about women's willingness to engage and preferences for online programmes. Objectives: This study explored pregnant women's attitudes towards and likelihood to undertake minimal online well-being training programmes (mindfulness, self-compassion, or general relaxation), engagement barriers and enablers, and programme structure preferences. Design: A mixed methods triangulation design was undertaken using a validating quantitative model. Quantile regressions were applied to the quantitative data. Content analysis was undertaken for the qualitative data. Methods: Consenting pregnant women (n = 151) were randomized equally to read about three online programme types. Participants were sent an information leaflet, tested by a consumer panel prior to distribution. Results: Participants generally held positive attitudes about all three types of interventions, with no statistically significant differences in preferences between programme types. Participants appreciated the importance of mental health and were receptive to fostering skills to support their emotional well-being and stress management. The most frequent perceived barriers were lack of time, tiredness, and forgetfulness. Programme structure preferences indicated one to two modules per week, less than 15 min in duration, and over 4 weeks. Programme functionality, such as regular reminders and easy accessibility, is important to end users. Conclusion: Our findings reinforce the importance of determining participant preferences in designing and communicating engaging interventions for perinatal women. This research contributes to the understanding of population-based interventions that can be provided as simple, scalable, cost-effective, and home-based activities in pregnancy for the benefit of individuals, their families, and society more broadly. Plain language summary: Title: Exploring ways to design appealing online programmes for pregnant women that reduce stress and develop positive coping skills Poor maternal mental health in pregnancy and during the first few years of a child's life can affect negatively on mother and child. As researchers, we want to look at accessible ways to support future mothers as early as possible, to assist both the woman and developing child. The Internet provides easy, low-cost access to support for online well-being programmes that reduce stress and develop positive coping skills. However, people frequently drop out of online programmes, particularly those that have minimal contact. Our research explored the likelihood of pregnant women undertaking web-based well-being programmes. We provided information to 151 pregnant women about three different types of brief, positive well-being programmes: a mindfulness skills programme, a programme developing self-compassion skills, and a programme for developing general relaxation skills. We asked the women a series of questions so that we could understand their interest, prospect of participating in the programmes, and what programme design appealed to them. The women in our study were generally positive about all three programme types and saw the benefits of developing skills to build their mental well-being and to manage stress. However, they felt they were time-poor and often tired. The women indicated preferences for programmes of one to two modules per week, less than 15 min long, over 4 weeks. They also indicated that regular reminders and easy accessibility are important. Pregnant women have a desire to use programmes to support their well-being and find meditation and relaxation practices acceptable. However, there are specific aspects of programme design that women prefer. This research contributes to understanding online programmes targeted to pregnant women which are simple and accessible and provide support at a critical life point for the mother and her child. Ignoring these preferences is likely to lead to poor initial engagement and high dropouts. [ABSTRACT FROM AUTHOR]

Background: Although the athleticism required of cheerleaders has increased, the risks of cheerleading have been less studied as compared with other sports. Purpose: To update our understanding of the epidemiology of cheerleading-related injuries. Study Design: Descriptive epidemiology study. Methods: We analyzed the National Electronic Injury Surveillance System (NEISS) for cheerleading-related injuries presenting to nationally representative emergency departments (EDs) in the United States from January 2010 through December 2019. Extracted data included patient age and sex, injury characteristics (diagnosis, body region injured, time of year, and location where injury occurred), and hospital disposition. Using patient narratives, we recorded the cheerleading skills, settings, and mechanisms that led to injury. NEISS sample weights were used to derive national estimates (NEs) from actual case numbers. Results: From 2010 to 2019, a total of 9868 athletes (NE = 350,000; 95% CI, 250,000-450,000) aged 5-25 years presented to US EDs for cheerleading injuries. The annual number of injuries decreased by 15%, from 982 (NE = 35,000; 95% CI, 27,000-44,000) to 897 (NE = 30,000; 95% CI, 18,000-42,000) (P =.048), corresponding to a 27% decline in the injury rate per 100,000 cheerleaders (P <.01). The annual number of injuries caused by performing stunts decreased by 24%, from 240 (NE = 8700; 95% CI, 6700-11,000) to 216 (NE = 6600; 95% CI, 4000-9200) (P =.01), with a 36% decline in the corresponding injury rate per 100,000 cheerleaders (P <.01). Despite these decreases, annual incidence of concussions/closed head injuries increased by 44%, from 128 (NE = 3800; 95% CI, 2900-4700) to 171 (NE = 5500; 95% CI, 3400-7700) (P =.02), and patients requiring hospital admission increased by 118%, from 18 (NE = 330; 95% CI, 250-410) to 24 (NE = 720; 95% CI, 440-1000) (P <.01). The hospital admission rate increased by 9.0% (P =.02). Conclusion: The number of cheerleading-related injuries presenting to US EDs decreased from 2010 to 2019. However, the incidence of concussions/closed head injuries and hospital admissions increased, suggesting that further measures are needed to improve safety for cheerleaders. [ABSTRACT FROM AUTHOR]

Two experiments conducted in a high-fidelity flight simulator examined the effects of guidance symbology, display size, and geometric field of view (GFOV) within a synthetic vision system (SVS). In Experiment 1, 18 pilots flew highlighted and low-lighted tunnel-in-the-sky displays, as well as a less cluttered follow-me aircraft (FMA), through a series of curved approaches over rugged terrain. The results revealed that both tunnels supported better flight path tracking and lower workload levels than did the FMA because of the availability of more preview information. Increasing tunnel intensity had no benefit on tracking and, in fact, degraded traffic awareness because of clutter and attentional tunneling. In Experiment 2, 24 pilots flew a lowlighted tunnel configured according to different display sizes (small or large) and GFOVs (30 degrees or 60 degrees). Measures of flight path tracking and terrain awareness generally favored the 60 degrees GFOV; however, there were no effects of display size. Actual or potential applications of this research include understanding the impact of SVS properties on flight path tracking, traffic and terrain awareness, workload, and the allocation of attention.

We examined the differential benefits of instructional materials for younger and older adults learning to use a home medical device. Participants received training on use of a blood glucose meter via either a user manual (a text guide with pictures) or an instructional video. Performance was measured immediately and then after a 2-week retention interval. Type of instruction was critical for determining older adults' performance. Older adults trained using the manual had poorer performance than did all other groups. After only 1 calibration, older adults who received video training performed as accurately as did the younger adults. Older adults' performance was more influenced by the retention interval; however, the benefit of the video training was maintained for the older adults across the retention interval. Confidence ratings paralleled subjective workload ratings. The data provide practical information to guide the development of training programs for systems that will be used by both younger and older adults; they also demonstrate the need for age-related usability testing even for training program design.
