A total of 429 young adults (mean age 20.7 years) recruited from different forums dedicated to video games took part in the study and filled a questionnaire including type of video game use, the Game Addiction Scale, the TAS-20 (evaluating alexithymia) and the HADS (evaluation anxiety and depression).
Since it has been demonstrated an association between alexithymia, measured with the TAS-20, and negative affect, an additional goal was to evaluate the correlation of TSIA with two measures of depression and anxiety (BDI-II and STAI-Y2).
Depression and anxiety scores in the migraine patients were highly correlated with each other and TAS-20 (r = 0.485, p = 0.001) and all its subscales in turn: difficulty in identifying (r = 0.435, p < 0.001) and describing feelings (r = 0.451, p = 0.001) and externally oriented thinking (r = 0.302, p = 0.001).
