“…For the measurement of internal consistency reliability, the researchers used the Cronbach's alpha of each construct. The results in Table 2 show that for each construct, the α values ranged between .729 and .835 while the CR values ranged between .833 and .915, thereby satisfying the minimum requirement of CR > .06 for internal consistency reliability (Kawakami et al, 2020;Gravesande et al, 2019), hence demonstrating the presence of adequate internal consistency reliability in the data. Content validity in the study was assured through a rigorous literature review relating to all three constructs (Pallant, 2016).…”

The expectancy value theory (EVT) has been used in many studies to predict the motivation processes of individuals with regard to how they think and act in particular ways. Critical to how individuals think and act are the three elements of the EVT, namely the expectancy cognition (expectancy), instrumentality cognition (instrumentality) and valence. This study therefore seeks to establish whether the EVT could be used to predict and explain the motivation of lecturers to apply culturally responsive pedagogies (CRPs) in the teaching of culturally heterogeneous classes in universities in Botswana. Using a sample of 291 lecturers from three selected universities, the study employed a structured questionnaire for data collection. Confirmatory factor analysis (CFA) was used for data purification. Structural equation modelling (SEM) using AMOS version 22 was used for data analysis. The study established that the expectancy (β = .419; p < .001) and instrumentality (β = .315; p < .001) cognitions of lecturers as well as the valence (β = .268; p < .001) had a significant influence on the motivation of lecturers to apply CRPs in the teaching of culturally heterogeneous classes in universities. These results also showed significant relationships between expectancy cognition and valence (β = .316; p < .001) and also between instrumentality cognition and valence (β = .301; p < .001). These results therefore demonstrate that the EVT could be used to predict the motivation of lecturers in universities to apply CRPs in their teaching of culturally diverse university students.

“…Six were excluded, as their answers deviated significantly between the first and second surveys. The correlation was judged to be very high if the correlation coefficient was 0.9 or more, high if it was between 0.7 and 0.9, relatively high between 0.4 and 0.7, low between 0.2 and 0.4, and no correlation if it was less than 0.2 [ 21 , 22 ].…”

Background: Food literacy (FL) is important as the ability to consider the unique aspects of food in our lives, society, and environment. The main objectives of this study were as follows: (1) to revisit the definition of FL, considering the cultural, relational, and ecological aspects that were often neglected in previous research, and (2) to develop a measurement tool for adults. Methods: Expert workshops, the Delphi survey, the test–retest survey, and one-on-one interviews were conducted. The content validity ratio was calculated from the Delphi survey. The correlation coefficient of each item was measured twice, and the Cronbach’s alpha was calculated. Results: This study proposed a new definition of FL, including future-oriented values, and suggested three main domains with 33 items: (1) 14 questions in nutrition and safety FL (Cronbach’s α = 0.877, average correlation coefficient = 0.70), (2) 8 questions in cultural and relational FL (Cronbach’s α = 0.705, average correlation coefficient = 0.71), and (3) 11 questions in socio-ecological FL (Cronbach’s α = 0.737, average correlation coefficient = 0.61). Conclusions: This newly developed questionnaire should be tested in different populations; however, this questionnaire can be a basis for measuring and improving FL for healthy, joyful, and sustainable diets for adults.

Background According to the United Nations, it is estimated that by 2050, the number of people aged 80 years and older will have increased by 3 times. Increased longevity is often accompanied by structural and functional changes that occur throughout an individual’s lifespan. These changes are often aggravated by chronic comorbidities, adopted behaviors or lifestyles, and environmental exposure, among other factors. Some of the related outcomes are loss of muscle strength, decreased balance control, and mobility impairments, which are strongly associated with the occurrence of falls in the elderly. Despite the continued undervaluation of the importance of knowledge on fall prevention among the elderly population by primary care health professionals, several evidence-based (single or multifaceted) fall prevention programs such as the Otago Exercise Program (OEP) have demonstrated a significant reduction in the risk of falls and fall-related injuries in the elderly within community settings. Recent studies have strived to integrate technology into physical exercise programs, which is effective for adherence and overcoming barriers to exercise, as well as improving physical functioning. Objective This study aims to assess the impact of the OEP on the functionality of home-dwelling elderly using a common technological platform. Particularly, the impact on muscle strength, balance, mobility, risk of falling, the perception of fear of falling, and the perception of the elderly regarding the ease of use of technology are being examined in this study. Methods A quasi-experimental study (before and after; single group) will be conducted with male and female participants aged 65 years or older living at home in the district of Porto. Participants will be recruited through the network COLABORAR, with a minimum of 30 participants meeting the study inclusion and exclusion criteria. All participants will sign informed consent forms. The data collection instrument consists of sociodemographic and clinical variables (self-reported), functional evaluation variables, and environmental risk variables. The data collection tool integrates primary and secondary outcome variables. The primary outcome is gait (timed-up and go test; normal step). The secondary outcome variables are lower limb strength and muscle resistance (30-second chair stand test), balance (4-stage balance test), frequency of falls, functional capacity (Lawton and Brody - Portuguese version), fear of falling (Falls Efficacy Scale International - Portuguese version), usability of the technology (System Usability Scale - Portuguese version), and environmental risk variables (home fall prevention checklist for older adults). Technological solutions, such as the FallSensing Home application and Kallisto wearable device, will be used, which will allow the detection and prevention of falls. The intervention is characterized by conducting the OEP through a common technological platform 3 times a week for 8 weeks. Throughout these weeks, the participants will be followed up in person or by telephone contact by the rehabilitation nurse. Considering the COVID-19 outbreak, all guidelines from the National Health Service will be followed. The project was funded by InnoStars, in collaboration with the Local EIT Health Regional Innovation Scheme Hub of the University of Porto. Results This study was approved on October 9, 2020 by the Ethics Committee of Escola Superior de Enfermagem do Porto (ESEP). The recruitment process was meant to start in October, but due to the COVID-19 pandemic, it was suspended. We expect to restart the study by the beginning of the third quarter of 2021. Conclusions The findings of this study protocol will contribute to the design and development of future robust studies for technological tests in a clinical context.
