Abstract
The present study investigated the validity of a global measure of self-actualization derived from the POI. The POI Inner-directed scale was related to numerous objective indices of self-actualizing characteristics (e.g., self-esteem, rigidity, empathy). Bivariate and multivariate correlational techniques presented a consistent picture of the self-actualizing dimensions tapped by the POI Id scale (e.g., self-esteem) as well as the self-actualizing characteristics unrelated to Id scale scores (e.g., machiavellianism). The results help to clarify the specific nature of the attributes measured by the Id scale, partially supporting its construct validity as an omnibus measure of actualizing tendencies. Finally, a new, face-valid measure of self-actualization is introduced which proved as valid as the POI as an index of self-actualization, with a considerable gain in parsimony.
