概要	Short form construct validity is the systematic evaluation of whether an abbreviated version of a psychological scale still measures the same underlying construct as the original full-length instrument. It combines item selection procedures with confirmatory factor analysis, convergent and discriminant validity tests, and criterion-related evidence to demonstrate that scale shortening has not compromised the meaning of measurement.	Short-form reliability analysis evaluates whether an abbreviated version of a psychological scale maintains acceptable internal consistency, validity, and structural integrity after items are removed. It is used in survey and assessment research to create briefer instruments that reduce respondent burden without sacrificing measurement quality.
