Development of the Conscious Sedation Scale: establishing content validity and reliability
1Center for GI and Special Procedures, Poudre Valley Hospital, Ft. Collins, CO 80524, USA.
Summary
The Consciousness Sedation Scale (CSS) shows good content validity for documenting patient responses during sedation. However, its reliability needs improvement for accurate patient assessment.
Area of Science:
- Medical Informatics
- Nursing Research
- Patient Safety
Background:
- Intravenous conscious sedation requires precise patient monitoring.
- Existing documentation tools may not fully capture patient responses.
- Standardized assessment is crucial for safe sedation practices.
Purpose of the Study:
- To evaluate the content validity and reliability of the Consciousness Sedation Scale (CSS).
- To assess the CSS as a documentation tool for patients undergoing intravenous conscious sedation.
- To determine if the CSS aligns with established goals for conscious sedation.
Main Methods:
- Instrument development based on Association of Operating Room Nurses guidelines.
- Content Validity Index (CVI) calculation to assess validity.
- Cronbach's coefficient alpha to measure reliability.
Main Results:
- The Consciousness Sedation Scale achieved a Content Validity Index (CVI) of .875, indicating strong content validity.
- Cronbach's alpha was .69, suggesting insufficient reliability for distinguishing between sedation grades.
- The study identified a need for further refinement of the CSS tool.
Conclusions:
- The CSS demonstrates adequate content validity for its intended use.
- The scale's current reliability is insufficient for precise clinical differentiation.
- Further modifications are necessary to enhance the CSS's reliability in clinical practice.
