According to the cognitive behavior theory and meta-cognitive theory of health anxiety, to examine the association between alexithymia, cognition factors or meta-cognition factors and health anxiety.
 Methods: A total of 1 164 medical students were investigated by the Short Health Anxiety Inventory, the Health Cognitions Questionnaire, the Meta-cognitions about Health Questionnaire and the Toronto Alexithymia Scale.
 Results: 1) Correlation analysis showed that alexithymia, dysfunctional beliefs, meta-cognition were significantly positively correlated with health anxiety (r=0.227-0.477, all P<0.01); 2) The results of structural equation model indicated that alexithymia could not exert effects on health anxiety directly (β=-0.05, 95% CI -0.123 to 0.021). The alexithymia could exert effects on health anxiety indirectly not only through dysfunctional beliefs (β=0.192, 95% CI 0.156 to 0.235), but also through the chain-mediated effect of dysfunctional beliefs and meta-cognitions (β=0.103, 95% CI 0.077 to 0.135). Dysfunctional beliefs fully mediated the relation between alexithymia and health anxiety (β=0.247, 95% CI 0.196 to 0.290).
 Conclusion: Alexithymia can affect health anxiety through the mediating effects of dysfunctional beliefs and meta-cognition.

A recent clinical trial found that parent-led CBT - in which parents led their child through a guided CBT workbook with varying degrees of therapist support - was efficacious for reducing anxiety and associated functional impairment. While such findings demonstrate promise for future intervention development and dissemination efforts with this population, more work is needed to elucidate clinical factors that impact response to treatment as well as drop-out.
