Mediation effects of post-series depression on the relationship between life satisfaction and positive mental health of Vietnamese: A cross-sectional study in COVID-19 pandemic context

Abstract

Vietnam, a middle-income country, has been suffering four waves of the Coronavirus disease 2019 (COVID-19) pandemic and a massive lockdown to suppress the spread of this infectious disease. Consequently, COVID-19 has caused psychological ramifications and affected humankind’s life satisfaction. Because of the lockdown period, numerous people had plentiful time. Hence, they found solace in excessive watching of television and movies, which could lead to post-series depression. The purpose of this study is to investigate the relationship between life satisfaction (LS), post-series depression (PSD), and positive mental health (PMH) and inquire about the mediation effect of satisfaction of life and PSD. A total of 2,572 participants who were voluntarily recruited from various media platforms completed self-report questionnaires, including the Satisfaction with life scale, Post-series depression scale, and Positive Mental Health Scale. This study was assessed using the PLS-SEM approach. The findings of this research discovered (i) a significantly positive effect of LS on PMH; (ii) a significantly negative effect of PSD on PMH; (iii) a significantly negative effect of LS on PSD, and (iv) a significant indirect effect of LS on PMH through PSD. The study provided additional evidence to the relationship between life satisfaction and PMH of individuals. Besides, the negative effects of PSD, which is a non-clinical term for feeling down that frequently appears after individuals finish their much-loved film and TV series, on individuals’ PMH is proved, especially in the COVID-19 pandemic context in which Vietnamese people must remain in their current location.
