Longitudinal study on affect, psychological well-being, depression, mental and physical health, prior to and during the COVID-19 pandemic in Spain

This longitudinal study, before and during the confinement of the COVID-19 pandemic, is to determine the evolution and effects on affect, psychological well-being, depression, and mental and physical health, during an ordinary week, from March 1 to March 7, in the week leading up to the establishment of confinement, from March 8 to March 14, and for several weeks of confinement, from March 15 to April 25. The most relevant results reveal significant differences between men and women in the confinement period, on almost all the scales of psychological well-being (SPWB), with the men obtaining a lower mean than the women. The analyses of the differences between the time periods show a significant difference in the Positive Affect scale (PANAS), the ordinary week group obtaining the highest score, and with this score decreasing in the pre-confinement week and the confinement period, and Negative Affect scale (PANAS) remained stable We found no significant differences in the participants' total depression score (BDI-II). S we obtained significant differences in the Role Physical and Physical Health Component scales (SF-36) between the pre-confinement week, with the highest mean, and the confinement.
