Mindfulness and acceptance have demonstrated associations with alexithymia facets. As a very limited body of research has explored the predictive strength among alexithymia-related constructs, this study aimed to investigate the prediction of alexithymia based on acceptance and mindfulness among students. The study group consisted of 586 university students, 237 (40.9%) females and 349 (59.1%) males. As for data collection, the five-factor mindfulness questionnaire, Acceptance and Commitment Questionnaire, and the Toronto Alexithymia Scale-2 were applied. A stepwise multiple linear regression was calculated to predict alexithymia based on components of commitment and action, mindfulness facets, and demographic variables (F[5,578] = 77.26, p ≤ 0.001), with an R2 of 0.41. The predictive variables including description (B = -0.59, t = -8.02, p < 0.001), commitment and action (B = -0.13, t = -4.38, p < 0.001), observation (B = -0.15, t = -2.94, p < 0.01), and no judgment (B = -0.16, t = -2.56, p < 0.05) exhibited significant prediction effects on the adjusted index of alexithymia. The findings contribute to the potential mechanism between mindfulness and alexithymia in intervention that seeks to improve mindfulness and acceptance skills and could prove more effective in treating patients with alexithymia.
