The THINC-integrated tool (THINC-it) appears to be valid and sensitive to detect cognitive deficits of adults with major depressive disorder (MDD) during a depressive episode and requires only 10 to 15 minutes to administer, researchers report in the Journal of Clinical Psychiatry.1
People age 18 to 65 years (n=100) with MDD were assessed with THINC-it during a major depressive episode of at least moderate severity. The results were compared with those of a matched group of healthy controls (n=100). The cognitive performance of 44% of the adults with MDD was at ≥1.0 standard deviation below that of the healthy controls on standardized mean scores of the THINC-it.
The researchers developed THINC-it—a computerized cognitive screening tool that assesses both objective and subjective cognitive measures—as a free, easy-to-administer measure that can be used by people with MDD.
In this study, based on a calculated composite score, the validity of the overall tool was judged to be acceptable (r=0.539, P <.001). The researchers point out that measuring cognitive function is important because it may be possible to improve it directly and independently by some treatment modalities.2-4
