{"abstract":"Individuals must communicate well with one another to be happy in their lives. However, nothing ever goes as planned. The Philippine government has instituted lockdowns, house quarantine, social isolation, and other procedures to prevent the spread of COVID-19. All Philippine schools and colleges made online study mandatory when the epidemic swept the country. Thus, this study investigates the relationship between happiness and anxiety among senior high school students. Based on the statistical analysis, happiness and anxiety have a significant relationship (r=.043).","abstract_source":"original","authors":["Ishi Keannly Mahinay","Dave Rollan","Christine Punzalan","Jana Marie Reyes","Dr. Jhoselle Tus"],"date":"2022-05-20","doi":"10.5281/zenodo.6565350","id":354,"issue":2,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"666f01197dcffb1ab6732d0bb951011f0d2d787adba53368ecbda5062fb41228","schema":"scimatic-article/1","title":"The Happiness and Its Relationship on the Anxiety of Senior High School Students During COVID-19 Pandemic","volume":2}
