Reliability, validity, and factor structure of the Cognitive Behavioral Rating Scale for stroke patients

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Psychometrics

Background:

• Assessing cognitive function in rehabilitation is crucial for patient outcomes.
• Observational tools are valuable for evaluating cognitive deficits.
• A validated scale is needed to objectively measure cognitive behavioral changes.

Purpose of the Study:

• To evaluate the reliability, validity, and factor structure of the Cognitive Behavioral Rating Scale (CBRS).
• To determine the psychometric properties of the CBRS for assessing cognitive function.
• To explore the utility of the CBRS in stroke and orthopedic patient populations.

Main Methods:

• The study involved 180 stroke patients and 58 orthopedic patients.
• The Cognitive Behavioral Rating Scale (CBRS) and Functional Independence Measure (FIM) were administered.
• Inter-rater reliability, construct validity, concurrent validity, predictive validity, and factor structure were analyzed.

Main Results:

• The CBRS demonstrated high inter-rater reliability (ICC=0.736) and internal consistency (Cronbach's α=0.92).
• Strong correlations were found between CBRS scores and FIM scores (rs=-0.70 to -0.72).
• The scale identified significant differences in cognitive function between patient groups and discharge dispositions, with a three-factor structure ('language and performance', 'control of performance', 'space-self relation').

Conclusions:

• The Cognitive Behavioral Rating Scale (CBRS) is a reliable and valid instrument for assessing cognitive function.
• The CBRS shows significant clinical utility in differentiating cognitive abilities among patient groups.
• The findings support the use of the CBRS in rehabilitation settings for cognitive assessment.
