Summary

A randomized placebo-controlled trial of arithmetic training (with the Kumon Method) as an errorless learning method for improvement of cognition in schizophrenia. Outpatients were included after signing an informed consent. The trial consisted of 48 sessions of arithmetic training (twice a week, for 6 months) or placebo (nonspecific recreation, 48 sessions). The patients were evaluated with a neuropsychological battery at baseline, after 6 months (end of intervention) and after 12 months after baseline. The Positive and Negative Syndrome Scale (PANSS) and the Personal and Social Performance scale (PSP) were applied at baseline, after 6 months (end of intervention) and 12 months after baseline. Primary outcome was the performance on three cognitive domains (attention, executive functions and working memory).

OTHER

cognitive training

The Kumon method (www.kumon.com) of arithmetic calculation employs the errorless-learning (EL) strategy and consists of a structured, hierarchical series of exercises, beginning with simple ones (e.g. addition and subtraction) and then proceeding to more complex exercises (e.g. advanced algebra, calculus).

OTHER

placebo

nonspecific recreation including befriending and free simple activities.
