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

This study examined the validity of the Self-expansiveness Level Form of Friedman with particular emphasis on the Transpersonal subscale, a measure of transpersonal self-concept, in terms of its basic psychometric properties and its relation to the NEO Personality Inventory--Revised. Support for the basic psychometric properties of the scale in terms of reliability, factorial validity, and concurrent validity was obtained; however, support was limited for convergent validity as correlations between scores on the Transpersonal subscale and measures of theoretically related constructs were low. Correlational analyses involving the Self-expansiveness Level Form and NEO Personality Inventory--Revised indicated that Transpersonal scores were not appreciably associated with the NEO Personality Inventory--Revised domains. Moreover, factor analysis of NEO Personality Inventory--Revised facets and Self-expansiveness Level Form items generated a solution in which the two measures contributed to separate factors. Discussion of the implications and limitations of the findings is included.
