Development, validity, and reliability of Neural Circuits Questionnaire (NCQ)

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychometrics

Background:

• Traditional models of brain function were cortico-centric.
• A parallel perspective emphasizes all neural structures.
• There was a need for a valid assessment tool for this parallel perspective.

Purpose of the Study:

• To develop and validate the Neural Circuits Questionnaire (NCQ).
• To assess cognitive function based on a parallel brain function model.
• To establish reliability and validity of the NCQ.

Main Methods:

• Exploratory factor analysis was used for data analysis.
• A sample of 183 university students participated.
• Receiver operating characteristic (ROC) curve analysis determined quality index cut-off points.

Main Results:

• The NCQ demonstrated a three-factor structure with a Cronbach's alpha of 0.617.
• The valid range for the quality index was determined to be 10.5-15.5.
• Ph.D. students exhibited a higher cerebro-cerebellar index compared to students with lower degrees (F=8.60, p=0.001).

Conclusions:

• The Neural Circuits Questionnaire (NCQ) is a valid and reliable instrument.
• The NCQ effectively assesses cognitive function through the lens of parallel brain function.
• Findings suggest academic level influences cerebro-cerebellar function.
