Аннотация:Background and Aims: Impairments of the executive functions are among the most common consequences of stroke, yet rehabilitation methods remain limited. We developed a specialized neuropsychological training program aimed at rehabilitating executive functions. The study’s aim was to evaluate the effects of this training on metacognition. According to D. Stuss, the metacognitive component of executive functions is responsible for awareness of mental states, self-reflection, social cognition, and the interpretation of others’ behavior.Methods: 48 patients with focal brain lesions participated (M = 58 years). The experimental group received the executive function training; the control group received non-specialized hospital rehabilitation. To assess metacognitive performance, the following tools were used: Proverb interpretation tasks, “Strange Stories” test (F. Happe), Interpretation of Bidstrup’s cartoon stories, Self-Awareness Deficit Interview (SADI).Results: Between-group analysis showed significantly better metacognitive scores in an experimental group after training (p = 0.025).Within-group analysis showed no significant changes in the control group (p = 0.924), whereas the experimental group demonstrated significant improvement (p = 0.045; d = 0.39) in the index and 8 individual test parameters, including self-awareness (SADI) and subtext understanding (Bidstrup test), with medium to large effect sizes (d = 0.45–0.83).Conclusions: The results support the efficacy of a short-term neuropsychological training program in improving metacognitive abilities. Improvements were observed in both self-awareness and the interpretation of others’ behavior. We hope that our study will open up new opportunities for neuropsychological rehabilitation in patients with executive disfunction.
