How does "locus of control" affect persons with epilepsy?

Purpose: Locus of control (LOC) is the degree to which people believe that they have control over the out -come of events in their lives. A person's locus can be internal, external, or chance. A person with internal locus of control believes that one can control one's own life. A person with external locus of control believes that his life is controlled by external factors or people over which he has no influence. A person with chance locus of control believes that fate, chance, or luck controls his own life. The aim of the current study was to determine the health locus of control, anxiety, and depression levels in persons with epi-lepsy (PWE) and to assess whether locus of control has relation to anxiety, depression, and seizure con-trol. Methods: Patients aged 18 years or older with a history of epilepsy for at least 1 year were recruited from the outpatient epilepsy clinic or from the inpatient epilepsy monitoring unit at SCTIMST, Trivandrum from January 2019 to May 2020. Patients filled the questionnaire form consisting of demographic data, age of onset of seizures, present seizure control, and the current antiepileptic drugs. The Hospital Anxiety and Depression (HAD) scale was used to estimate the level of anxiety and depression in these patients. The Form-C of the Multidimensional Health Locus of Control (MHLC) scale was used to evaluate the health locus of control. Healthy controls aged 18 years or older and free of any chronic disease or psy-chiatric illness were also recruited. They were asked to fill the questionnaire forms with basic demo-graphic data. HAD scale was used to estimate the level of anxiety and depression and form-C of MHLC was used to evaluate the health locus of control in the healthy controls. The mean scores of anxiety, depression, and locus of control were compared between the two groups. Results: A total of 170 participants were recruited which consisted of 100 PWE and 70 healthy controls. The mean anxiety and depression scores were 8.13(SD = 4.23) and 5.85(SD = 3.66) in the PWE group and 6.75(SD = 3.39) and 4.14(SD = 2.96) in the control group, respectively. The mean internal, external, and chance LOC scores were 24.95(SD = 10.92), 26.94(SD = 4.96), and 24.41(SD = 6.46) in the PWE group; and 29.44(SD = 5.62), 26.53(SD = 5.79), and 19.9(SD = 7.13) in the control group, respectively. Persons with epilepsy had higher chance LOC scores and lower internal LOC scores compared to con-trols (p = 0.00003, p < 0.00001 respectively). There were no differences in the external LOC scores between the two groups (p = 0.620). Persons with epilepsy with some level of anxiety had lower internal LOC scores compared to patients with no anxiety (p = 0.04). PWE with poor seizure control had higher external LOC score and lower internal LOC scores which however did not reach statistical significance. Persons with epilepsy with poor seizure control had higher anxiety and depression scores. Conclusions: Persons with epilepsy had low perceptions of internal and strong perceptions of chance health locus of control. This means that PWE feel that luck plays an important role in their disease con-trol. This information is important in the counseling of persons with epilepsy. (c) 2021 Elsevier Inc.
