The Japanese version of the Phenomenological Control Scale

Area of Science:

• Psychology
• Cognitive Science
• Psychometrics

Background:

• Individual differences exist in phenomenological control, the ability to align perception with intentions.
• The Phenomenological Control Scale (PCS) measures this trait, but a Japanese version was needed.

Purpose of the Study:

• To develop and validate a Japanese version of the Phenomenological Control Scale (PCS-J).
• To assess the reliability and validity of the PCS-J in a Japanese sample.

Main Methods:

• Development and validation of the PCS-J using preregistered online surveys.
• Assessed internal consistency, test-retest reliability, convergent validity (positive schizotypy), and discriminant validity (negative schizotypy).

Main Results:

• The PCS-J demonstrated sufficient internal consistency and test-retest reliability.
• Convergent validity was supported by a weak positive correlation with positive schizotypy.
• Discriminant validity was supported by the absence of a correlation with negative schizotypy.

Conclusions:

• The PCS-J is a reliable and valid measure of phenomenological control in Japanese samples.
• The PCS-J will be valuable for research on perception, phenomenological control, and individual differences in Japan.
• This scale facilitates cross-cultural research on perceptual control.
