DocTalks on TikTok: Self-Diagnosis Among Young Adults Exposed to Mental Health Trends Online

The rise of social media platforms like TikTok has significantly influenced the mental health landscape among young adults, particularly in the realm of self-diagnosis. This study explored the self-diagnosis experiences of young adults exposed to mental health content on TikTok. This qualitative phenomenological study explored the self-diagnosis experiences of 14 young adults aged 18 to 25, selected based on regular TikTok use for at least one year, confessed to self-diagnose because of mental health content on TikTok, and a minimum score of 14 on the Self-Diagnosis Scale. Using semi-structured interviews and thematic analysis, findings were validated through member checking and the critical friend technique. The study found that participants engaged with mental health content on TikTok due to its informative, entertaining nature and algorithmic influence, describing their engagement as both active and passive. This interaction prompted self-diagnosis through introspection, self- labeling with mental disorders, and seeking additional information. The practice affected participants’ mental health emotionally, cognitively, and behaviorally, with participants recognizing both the benefits and limitations of self-diagnosis. While self-diagnosis fosters awareness and reduces stigma, its risks emphasize the need for accessible resources, reliable information, and professional support to overcome barriers.
