THE VALIDITY AND RELIABILITY OF THE CHULA COVID-19 PSYCHOSOCIAL HOME ISOLATION EVALUATION TOOL (CCPHIET)
Abstract
Objectives
The growing number of COVID-19 cases during the pandemic have led to a significant shortage of hospital beds. Many patients may not require hospitalization and can be clinically observed in home settings. We have identified psychosocial factors that correlate with unsuccessful home isolation (HI), which in turn might negatively affect the transmission control in the community. Therefore, we developed the Chula COVID-19 Psychosocial Home Isolation Evaluation Tool (CCPHIET), a new screening tool for assessing the psychosocial suitability for HI.
Methods
This cross-sectional descriptive study included COVID-19 patients who were deemed to be medically safe for 14-days of HI. The CCPHIET is comprised of 8 clinical domains pertinent to HI behavioral compliance and risk for non-adherence. We explored its statistical validity and reliability and discussed the potential utility of this tool.
Results
A total of 65 COVID-19 patients participated in this study. Most patients (58.5%) were deemed to be good candidates for HI. The results of this study demonstrate that the CCPHIET has an acceptable content validity (IOC index > 0.5), moderate internal consistency (Cronbach’s alpha = 0.611) and substantial to excellent inter-rater reliability (Intraclass correlation coefficient = 0.944, Cohen’s kappa= 0.627).
Conclusions
The CCPHIET is an easy-to-use tool for assessing the psychosocial suitability of patients for at home isolation for patients with mild and asymptomatic COVID-19. Its implementation can assist clinicians in identifying and redirecting resources to patients at highest risk for breaking quarantine and save in unnecessary, costly absolute institutional quarantine for those deemed to be psychosocially fit for full adherence.
