RESUMO
OBJECTIVE: This study examined the differences in first-year college students' daily change trajectories in subjective happiness, depression, anxiety, stress, and state mindfulness. METHOD: A 5-day, online mindfulness-based intervention (MI) condition and stress management (SM) condition were employed in 247 first-year college students. RESULTS: Students in both the MI and SM conditions displayed similar significant linear declines in anxiety and stress, but there were significant differences between the two conditions, including: (1) the MI condition showing a significant linear increase in subjective happiness compared with no change in the SM condition and (2) the SM condition showed a significant linear decrease in depression compared to no significant change in the MI condition. CONCLUSION: Brief online interventions-whether MI or SM-can promote better mental health and reduce psychological distress. The results also lend support for MI's differential influence on first-year college students' happiness and SM's differential influence on their depression.
