This thesis explores how single parents utilise online forums, particularly Reddit, to navigate parenting challenges and mental health issues. The study involves a mixed-method approach which includes sentiment analysis and thematic analysis. Through a comprehensive analysis of forum posts and comments, the research identifies key themes and support mechanisms expressed by single parents in addition to the quantitative data from sentimental analysis representing the emotional tone of the text in the posts. The findings reveal that online communities serve as crucial platforms for emotional support, knowledge exchange, and community building. This research contributes to understanding the role of digital spaces in supporting single parents and offers insights for designing more effective online social support intervention by addressing AI-driven features, expert moderation and bridging the gap between online and offline social support for single parents.
