Effect of Gender on Reaction Time in Patients Having a Psychiatric Disorder

Abstract

Background: Reaction time is a measure of how fast an organism can react to a certain stimulus. As such, it is a measure of an individual’s performance and the function of sensory-motor connection. While there are studies evaluating the differences in reaction time with gender and psychiatric illness as independent variables, data are lacking when considering them together. Aims: The aim of the study is to study the gender differences in reaction time in patients suffering from psychiatric illness. Settings and Design: The study involves an observational, longitudinal comparative study in the psychiatric outpatient department (OPD) of a tertiary care facility. Materials and Methods: After institutional ethics approval, 100 patients on psychotropic medications attending psychiatry OPD were included in the study along with at least 100 relatives who were not on psychotropic medications, serving as control. Required data were collected using semi-structured pro forma. The reaction time of patients and the control group was assessed using an application on the mobile phone available online as – the “Human Benchmark test.” Data obtained were entered in the MS Excel sheet and analyzed using the computerized software and a P ≤ 0.05 was considered statistically significant. Results: In the group of patients, the males showed delayed reaction time as compared to females, while in the control group, males performed better than the female population in reaction time tests. The highest reaction time was found to be in the substance use disorder group of patients at all points of testing, followed by that of patients with schizophrenia. Conclusions: Gender did not significantly affect the reaction time in both patient and control groups.
