The authors (Lee et al. Reference Lee, Redoblado-Hodge, Naismith, Hermens, Porter and Hickie2013) assume that meta-cognitions, such as self-efficacy might explain social and role functioning improvements of the group treated with cognitive remediation.
According to our own data (Trebo et al. Reference Trebo, Holzner, Pircher, Prunnlechner and Günther2007; Stürz et al. Reference Stürz, Hartmann, Eder-Pelzer and Günther2011), computer-assisted cognitive training leads to significant declines in depression scores (compared to control groups) in mildly (Beck Depression Inventory: mean = 17) and moderately (Beck Depression Inventory: mean = 25) depressed patients.
In our two studies mentioned above, we also assessed dysfunctional meta-cognitions as attributional styles and found that they were not significantly altered by computer-assisted cognitive training. Therefore, we propose that the improvement in social functioning scores reported by Lee et al. (Reference Lee, Redoblado-Hodge, Naismith, Hermens, Porter and Hickie2013) might have been mediated by mood stabilization because their sample was mildly depressed according to the reported Hamilton scores. These authors did not present post-treatment HAMD scores.
