Adaptation of the Fear of COVID-19 Scale: Its Association with Psychological Distress and Life Satisfaction in Turkey.

Abstract: The world is currently experiencing a pandemic of an infectious disease called COVID-19 which has drawn global intensive attention. While global attention is largely focusing on the effects of the coronavirus on physical health, the impacts of the coronavirus on psychological health cannot be overlooked. Therefore, this study aims to adapt the Fear of COVID-19 Scale into Turkish and investigate the relationships between fear of COVID-19, psychological distress, and life satisfaction. Data were collected by convenience sampling method, which allowed us to reach total 1304 participants, aged between 18 and 64 years, from 75 cities in Turkey. In the adaptation process of the Fear of COVID-19 Scale, confirmatory factor analysis, Item Response Theory, convergent validity, and reliability (Cronbach's α, McDonald's ω, Guttmann's λ6, and composite reliability) analyses were performed. Additionally, the mediating role of psychological distress on the relationship between fear of COVID-19 and life satisfaction was tested. The uni-dimensionality of the 7-item scale was confirmed on a Turkish sample. Item Response Theory revealed that all items were coherent and fit with the model. The results indicated that the Turkish version of the scale had satisfactory reliability coefficients. The fear of COVID-19 was found to be associated with psychological distress and life satisfaction. Results indicated that the Turkish version of the Fear of COVID-19 Scale had strong psychometric properties. This scale will allow mental health professionals to do research on the psychological impacts of COVID-19 in Turkey.

Active Packaging Applications for Food.

Abstract: The traditional role of food packaging is continuing to evolve in response to changing market needs. Current drivers such as consumer's demand for safer, "healthier," and higher-quality foods, ideally with a long shelf-life; the demand for convenient and transparent packaging, and the preference for more sustainable packaging materials, have led to the development of new packaging technologies, such as active packaging (AP). As defined in the European regulation (EC) No 450/2009, AP systems are designed to "deliberately incorporate components that would release or absorb substances into or from the packaged food or the environment surrounding the food." Active packaging materials are thereby "intended to extend the shelf-life or to maintain or improve the condition of packaged food." Although extensive research on AP technologies is being undertaken, many of these technologies have not yet been implemented successfully in commercial food packaging systems. Broad communication of their benefits in food product applications will facilitate the successful development and market introduction. In this review, an overview of AP technologies, such as antimicrobial, antioxidant or carbon dioxide-releasing systems, and systems absorbing oxygen, moisture or ethylene, is provided, and, in particular, scientific publications illustrating the benefits of such technologies for specific food products are reviewed. Furthermore, the challenges in applying such AP technologies to food systems and the anticipated direction of future developments are discussed. This review will provide food and packaging scientists with a thorough understanding of the benefits of AP technologies when applied to specific foods and hence can assist in accelerating commercial adoption.
