An Arabic Translation, Reliability, Validity, and Feasibility of the Richards-Campbell Sleep Questionnaire for Sleep Quality Assessment in ICU: Prospective-Repeated Assessments

Background and Purpose: To translate Richards-Campbell Sleep Questionnaire (RCSQ) into the Arabic language (RCSQ-A), to assess content validity of the translated tool, to analyze the internal consistency, and to evaluate its feasibility. Methods: A rigorous translation was completed using the process of translation by World Health Organization. Cognitive debriefing interviews were performed. Repeated assessments using RCSQ-A was conducted in critical care patients in Saudi Arabia. Result: Cronbach's alpha of.89 was seen in the RCSQ-A. The cognitive interviews showed that the RCSQ-A well understood and interpreted correctly and consistently. Fifty-seven participants reported their sleep using RCSQ-A a total of 110 times. Conclusion: RCSQ-A has adequate translation validity, provided good internal consistency and content validity, making it suitable for use as a measurement tool in practice and research in Arabic-speaking countries.
