Abstract:
The significant growth in social media usage has notably affected students' life
patterns, mental well-being, and social interactions. However, limited studies have
investigated the mediating role of mental health in this relationship within the Sri
Lankan undergraduate context. This study explored the impact of social media
addiction on life satisfaction, with the mediating effect of mental health among Sri
Lankan management undergraduates. A quantitative approach was adopted, and data
were collected from 221 participants representing 4 state universities using a
questionnaire based on the Bergen Social Media Addiction Scale (BSMAS),
Satisfaction with Life Scale (SWLS), and Depression Anxiety and Stress Scale
(DASS-21). Data analysis was conducted using IBM SPSS Statistics 25 software.
Results revealed that 74.2% of undergraduates spend more than 3 hours per day on
social media, and Facebook is the social media platform they most often use during
their free time. According to results, there is a significant negative relationship
between social media addiction and life satisfaction (β = -.2527, p < 0.05), and there
is a significant positive relationship between social media addiction and mental health
(β = .4933, p < 0.05). However, the positive relationship between mental health and
life satisfaction is not statistically significant (β =.7254, p > 0.05), and the
bootstrapped indirect effect Further confirmed it (effect = -.0157). The study
highlights the need for university-based mental health awareness programmes and the
addition of digital health education. Future researchers could replicate this study with
a larger sample in different contexts. They could also study the effects of other
mediators, and a longitudinal method could also be used to study long-term effects.
