The Self-Expansiveness Level Form: examination of its validity and relation to the Neo Personality Inventory--Revised

Area of Science:

• Psychology
• Psychometrics

Background:

• The Self-expansiveness Level Form (SELF) measures self-concept.
• The Transpersonal subscale of the SELF assesses transpersonal self-concept.
• Understanding the psychometric properties of the SELF is crucial for its application.

Purpose of the Study:

• To evaluate the psychometric properties of the SELF, focusing on the Transpersonal subscale.
• To examine the relationship between the SELF's Transpersonal subscale and the NEO Personality Inventory--Revised (NEO-PI-R).

Main Methods:

• Assessed reliability, factorial validity, and concurrent validity of the SELF.
• Investigated convergent validity by correlating the Transpersonal subscale with related constructs.
• Conducted correlational analyses between the SELF and the NEO-PI-R.
• Performed factor analysis on items from both measures.

Main Results:

• The SELF demonstrated adequate reliability, factorial validity, and concurrent validity.
• Convergent validity for the Transpersonal subscale was limited, with low correlations to related measures.
• Transpersonal scores showed minimal association with NEO-PI-R domains.
• Factor analysis indicated that the SELF and NEO-PI-R loaded on separate factors.

Conclusions:

• The SELF possesses sound psychometric properties but requires further validation regarding convergent aspects.
• The Transpersonal subscale of the SELF is not strongly associated with the personality domains measured by the NEO-PI-R.
• Future research should explore the distinctiveness of transpersonal self-concept as measured by the SELF.
