Validation of stress assessment instruments related to the COVID-19 pandemic in pregnant women

Background: The Pandemic Related Pregnancy Stress Scale (PREPS) is an instrument that assesses pandemic-related stress in pregnant women. Objective: This study aimed to validate the Indonesian version of the Pandemic Related Pregnancy Stress Scale (PREPS). Methods: Validation procedures include forward and backward translation, pretest and cognitive interview, construct validity test, and instrument reliability test. Pregnant women involved in this study agreed to participate with informed consent. Results: The results of the construct validity test showed that each item of the PREPS questionnaire statement had an r(count) > r(table) (alpha=0.01; df=28), starting from the lowest 0.562 to the largest 0.847, with an r(table) value (alpha=0.01; df = 28) equal to 0.3610. The Cronbach's alpha value of 0.841 indicates good reliability of the scale. Conclusion: The Indonesian version of the PREPS is valid and has good reliability.
