Development of an evidence-based digital service platform for youth mental health care using natural language processing technology

Modest decreases in loneliness and depression post-intervention were observed, although not statistically significant (likely due to small sample size). Welch's ANOVA found no significant differences between intervention groups (UCLA Loneliness: P=.5917; PHQ-9: P=.5058). Qualitative data indicated user satisfaction, with suggestions for improved app effectiveness and personalization. Conclusions: Despite limitations, the study suggests the potential of well-designed digital interventions in alleviating college students' loneliness and depression. Findings underscore the importance of accessible digital tools, mental health literacy education, and comprehensive support systems. Further research with larger samples is needed.
