RCSQ: Systematic Review of Psychometric Properties for ICU Sleep Assessment

A systematic review by Yanting Zhang, last updated in May 2026, assesses the measurement properties of the revised Richards-Campbell Sleep Questionnaire (RCSQ). The review includes 14 studies covering eight language versions, primarily from Asian countries, and evaluates samples including ICU patients, older inpatients, and acute stroke patients. It was conducted according to PRISMA 2020 guidelines and uses COSMIN criteria for quality assessment.

Use Cases

• Evaluating the internal consistency of sleep questionnaires based on the reported good performance across most RCSQ versions.
• Identifying gaps in validation for key measurement properties like content or structural validity as highlighted in the review's conclusions.
• Informing the design of future validation studies for the RCSQ based on the methodological quality and risk of bias assessment.
• Comparing psychometric evidence across different translated versions of the RCSQ used in various patient populations.

Strengths

• The review is based on a systematic search of 8 major databases from inception to August 2024.
• It includes 14 studies evaluating eight different language versions of the revised RCSQ.
• Methodological quality was assessed using established COSMIN and JBI criteria.
• The dataset is openly shared under a CC-BY-4.0 license.

Limitations

• The dataset is a 17.5 KB document (DOCX), indicating a very limited scope as a review summary rather than primary data.
• Row and column counts are unknown; the document's internal data structure requires inspection after download.
• The review notes that evidence for key measurement properties like content validity was underreported or insufficient across studies.
