Abstract

Introduction: Aim of current study is to compare cognitive condition of schizophrenic inpatients of psychiatric hospital and healthy individuals. Materials and Methods: This study is a practical research and with respect to nature and method is casual-comparative research. Statistical Society of this society consisted of 73 inpatients schizophrenic patients, who were admitted to Zare psychiatric hospital between 2015-2016. Sample Size Determination was done via Krejcie and Morgan Table and sample size reduced to 60 patients. In order to choose sample, random sampling method was used. Field data collection and library were used regarding obtaining data; GHQ28 and Wechsler Adult Intelligence Scale were used. Reliability of the test was 0.77 according to Cronbach’s alpha. We assessed hypotheses of this study via SPSS software and univariate t-analysis. Results and Conclusion: A result of the study is demonstrative of meaningful difference between similarities, picture completion and information between case group and control group. However, no meaningful difference was noticed in aforementioned subtests with respect to duration of this disorder.
