One of the far-reaching impacts of the COVID-19 pandemic is that it has become the fertile soil of cyberchondria. Adolescents' mental health was severely hit by this by-product of the COVID-19 pandemic both due to the direct effects and its indirect effects on security. This study investigated whether and how cyberchondria was associated with Chinese adolescents' mental health (i.e., well-being and depressive symptoms). Based on a large Internet sample (N = 1,108, 67.5 percent female, Mage = 16.78 years), cyberchondria, psychological insecurity, mental health, and a series of covariates were assessed. Preliminary analyses were conducted in SPSS Statistics software and main analyses were conducted in Mplus. Path analyses indicated that (a) cyberchondria was negatively associated with well-being (b = -0.12, p = 0.001) and positively associated with depressive symptoms (b = 0.17, p < 0.001); (b) psychological insecurity could fully mediate the association between cyberchondria and mental health (indirect effect well-being = -0.15, 95% confidence interval [CI -0.19 to -0.12] and indirect effect depressive symptoms = 0.15, 95% CI [0.12 to 0.19]); (c) the two dimensions (social insecurity and uncertainty) of psychological insecurity could play the mediating role in the associations between cyberchondria and mental health, uniquely and parallelly; and (d) these results did not vary by gender. This study suggests that cyberchondria may arouse individuals' psychological insecurity about interpersonal interaction and the development of events, which ultimately decreases their well-being and increases the risk of depressive symptoms. These findings facilitate the establishment and implementation of relevant prevention and intervention programs.
