Effects of an extrinsic motivator on the evaluation of cognitive and daily living functions in patients with schizophrenia.

We investigated the effect of an extrinsic motivator on the MATRICS Consensus Cognitive Battery (MCCB) and UCSD Performance-Based Skills Assessment (UPSA) scores, which assess cognitive and daily living functions, in patients with schizophrenia. We enrolled 60 clinically stable patients with schizophrenia and allocated them to the motivator or control group. We conducted baseline assessments of cognitive function using the MCCB, daily living function using the UPSA, clinical symptoms, and psychosocial characteristics in both groups.

Developing clinical cut-off scores for the university of California San Diego performance-based skills assessment in patients with schizophrenia.

This study aimed to obtain University of California San Diego Performance-based Skill Assessment (UPSA) cut-off scores for the purpose of severity classification and to expand the clinical utility of the UPSA for the evaluation of cognitive function in patients with schizophrenia. In total, 191 patients with schizophrenia were recruited. The UPSA, Positive and Negative Symptom Scale (PANSS), Clinical Global Impression-Schizophrenia Scale (CGI-SCH), and Global Assessment Functioning Scale (GAF) were used for the evaluation.

The effect of anticholinergic burden on cognitive and daily living functions in patients with schizophrenia.

Objective: This study aimed to explore the association between medication-associated anticholinergic burden and cognitive and daily living functions in patients with schizophrenia.

Methods: Sixty patients with schizophrenia were recruited. We used the Anticholinergic Drug Scale (ADS) for evaluating medication-associated anticholinergic burden.

Adjunct transcranial direct current stimulation improves cognitive function in patients with schizophrenia: A double-blind 12-week study.

Objectives: Cognitive impairment is a common symptom of schizophrenia that has significant effects on quality of life and the activities of daily living. The present study examined the ability of transcranial direct current stimulation (tDCS) to improve cognitive function and clinical symptoms in patients with schizophrenia.

Methods: Fifty-six patients with schizophrenia were randomized to real-tDCS and sham-tDCS groups.

The Korean Version of the University of California San Diego Performance-based Skills Assessment: Reliability and Validity.

Objective: The study's aim was to develop and standardize a Korean version of the University of California San Diego Performance-based Skills Assessment (K-UPSA), which is used to evaluate the daily living function of patients with schizophrenia.

Methods: Study participants were 78 patients with schizophrenia and 27 demographically matched healthy controls. We evaluated the clinical states and cognitive functions to verify K-UPSA's reliability and validity.

The Korean Version of the Schizophrenia Cognition Rating Scale: Reliability and Validity.

Objective: This study's aim was to develop and standardize a Korean version (SCoRS-K) of the Schizophrenia Cognition Rating Scale (SCoRS), which is used to evaluate the degree of cognitive dysfunction affecting the everyday functioning of people with schizophrenia.

Methods: Eighty-four schizophrenia patients with stable symptoms who were receiving outpatient treatment and rehabilitation therapy, and 29 demographically matched non-patient controls, participated in the study. Demographic data were collected, and clinical symptoms, cognitive function, and social function were evaluated to verify SCoRS-K's reliability and validity.
