Abstract
Aim/Background: Mental-health problems among coronavirus disease 2019 (COVID-19) inpatients is an underinvestigated issue. The study reported herein was conducted to assess obsessive-compulsive, borderline, schizoid and narcissistic personality disorder beliefs and the influence of these dysfunctional beliefs on the anxiety and depression levels of COVID-19 inpatients.
Methods: A total of 75 COVID-19 inpatients were recruited for the study. Their anxiety and depression levels were evaluated using Hospital Anxiety and Depression Scale, and the aforementioned personality disorder beliefs were evaluated using Personality Belief Questionnaire-Short Form.
Results: According to the cut-off values, 9.3% (n = 7) of the inpatients were considered having anxiety and 34.7% (n = 26) were considered having depression. The mean scores for obsessive-compulsive, schizoid, borderline and narcissistic personality disorder beliefs were 15.1 ± 6.2, 12.9 ± 6.0, 10.0 ± 5.5 and 9.4 ± 5.6, respectively. The anxiety levels of the female inpatients were significantly higher than those of the male inpatients (z = 2.152; p = 0.031). The inpatients’ borderline personality disorder belief scores were significantly correlated with their anxiety levels (r = 0.390; p = 0.001).
Conclusion: The study participants’ obsessive-compulsive personality disorder beliefs were higher than their other aforementioned personality disorder beliefs. Female gender and borderline personality disorder beliefs were found to be related with anxiety level. The influence of these factors should be considered in the evaluation of COVID-19 inpatients in daily clinical practice.
