{"abstract":"Schools and universities were closed during the COVID-19 pandemic to prevent the virus from spreading. The ineffective operations of universities and schools significantly impacted the educational system's shift from traditional face-to-face instruction to online study. Hence, this study investigates the relationship between happiness and depression among college students amidst the online learning modality. Based on the statistical analysis, there is a significant relationship between happiness and depression (r=.128) among college students during the implementation of online learning.","abstract_source":"original","authors":["Rica Abesamis","Dr. Jhoselle Tus"],"date":"2022-05-12","doi":"10.5281/zenodo.6541673","id":347,"issue":2,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"d825a59625e1cf4ca317cb392c1e569932f141c755c7d1bf8ae8bd0c2e4294e9","schema":"scimatic-article/1","title":"Happiness and Depression Among College Students Amidst the Online Learning","volume":2}
