Reliability and validity of critical care orientation tests

Area of Science:

• Nursing Education
• Healthcare Professional Assessment
• Measurement in Health Sciences

Background:

• Orientation programs are crucial for ensuring competency in critical care nursing.
• Standardized testing is essential for evaluating the effectiveness of orientation programs.
• Existing orientation tests may lack established reliability and validity.

Purpose of the Study:

• To establish the reliability and validity of multiple-choice orientation tests for critical care nurses.
• To evaluate the psychometric properties of 10 newly developed orientation tests.
• To provide a framework for developing and validating healthcare education assessments.

Main Methods:

• A criterion-referenced measurement framework was used to develop 10 tests across five content areas.
• Tests were administered to 40 critical care nurses and 31 medical-surgical nurses.
• Standard psychometric analyses, including test-retest, parallel forms, construct validity, and item analysis, were performed.

Main Results:

• Parallel form correlations ranged from .46 to .90 (P < .05), and test-retest correlations ranged from .56 to .93 (P < .01).
• Significant differences (P < .01) in scores were observed between critical care and medical-surgical nurses on nine tests.
• The results supported the reliability and validity of the developed orientation tests.

Conclusions:

• The multiple-choice orientation tests demonstrate acceptable reliability and validity for critical care nurses.
• The study provides a validated process for developing and assessing educational tests in specialized nursing fields.
• These findings contribute to improving the quality and standardization of critical care nurse orientation.
