Cognitive dysfunction and its relationship with psychopathology and quality of life in patients with schizophrenia: a protocol for a cross sectional study

Abstract

Background One central characteristic of schizophrenia is cognitive dysfunction, which typically has modest to severe effects on a variety of cognitive areas. Evidence suggests that cognitive impairment may occur far sooner than the clinical symptoms. The connection between cognitive deficiencies and functional outcome indicators has attracted increasing attention in recent years. Cognitive deficits are widely known to affect overall functioning, In India, few studies have been conducted to determine the profile of cognitive abnormalities in individuals in the chronic phase of schizophrenia as well as those in remission. Research from developing nations is crucial because schizophrenia prevalence in these nations is thought to be lower than that in industrialized nations. The aim of this study will be to assess the prevalence of cognitive dysfunction in individuals with schizophrenia and examine the relationship between cognitive dysfunction with psychopathology and quality of life in individuals with schizophrenia. Protocol This will be a cross sectional hospital-based study. After ethical clearance, all patients in the Psychiatry Department meeting the criteria of Schizophrenia, according to the ICD-10, will be part of the study. The expected number of participants is 228. All participants within the age group of 18 to 65 years who are clinically diagnosed to have schizophrenia using ICD-10 and who are able to give written informed consent will be included in the study. The patient’s sociodemographic data will be collected in Outpatient or inpatient basis and then the following questionnaires will be applied to them: i) Socio-demographic Proforma; ii) The Positive and Negative Syndrome Scale (PANSS); iii) The World Health Organization Quality of Life-BREF scale (WHOQOL-BREF); and iv) Addenbrooke’s cognitive examination III (ACE). Once the aforementioned questionnaires are completed, the prevalence of cognitive dysfunction in patients with schizophrenia will be assessed, and its relationship with psychopathology and quality of life will be studied.
