However, there is a paucity of research on how eMHL varies across age groups. Objective: This study aimed to investigate differences in eMHL among young, middle-aged, and older adults; provide insightsinto the needs, behaviors, and attitudes of different age groups in relation to digital mental health resources; and ultimately, informthe improvement of mental health services.Methods: A qualitative investigation was conducted to examine the differences in eMHL across different age demographics inthe Chinese population in 2023. The study sample comprised 3 distinct age groups: 18-34 years, 35-64 years, and 65 years andolder. Participants were recruited through purposive sampling to ensure a diverse representation of the population. Data werecollected through semistructured one-on-one interviews, which allowed for in-depth exploration of individual experiences andperceptions. The gathered data were subsequently subjected to rigorous thematic analysis to enable the identification andinterpretation of recurring patterns and themes. Results: The principal outcomes derived from these interviews were synthesized into 5 distinct dimensions: emotional needs,use of digital mental health resources, assessment of digital mental health information, engagement with social media to regulateemotions, and coping strategies. These dimensions were uniformly observed across the 3 age groups. Conclusions: We identified differences in knowledge, skills, and attitudes regarding the use of web-based information formanaging mental health problems between the 3 age groups. The findings highlight the importance of age-specific strategies forimproving eMHL
