The Validity and Reliability of the Indonesian Version of Post-Intensive Care Syndrome Questionnaire (PICSQ) for Intensive Care Unit Survivors.

Abstract

Background: Post-Intensive Care Syndrome (PICS) encompasses cognitive, motor, and mental impairments persisting for years in ICU survivors. Despite its significance, the prevalence of PICS in Indonesia remains uncertain due to limited research and a lack of validated measurement tools. This study aims to translate and validate the PICS Questionnaire for use among ICU survivors in Indonesia.

Methods: The study followed a two-phase approach: translation and evaluation. The translation phase adhered to the 10-step process of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) guidelines. The analysis phase involved 184 subjects, using Confirmatory Factor Analysis (CFA) for validation and Cronbach's α and Intraclass Correlation Coefficient (ICC) for reliability testing.

Results: The CFA reported factor loadings (λ >0.40) for each item in its relevant domain. Fit index values indicated a good-to-acceptable fit. Internal reliability was high for the mental, physical, and cognitive domains (0.812 vs. 0.779 vs. 0.855), with Cronbach's α of > 0.70. Test-retest reliability and ICC demonstrated dependable results (>0.70) for each domain.

Conclusion: The translated and validated Indonesian PICS Questionnaire demonstrates good validity and reliability. This tool will enable healthcare professionals to assess PICS among ICU survivors in Indonesia and facilitate further research on its prevalence and impact on quality of life.
