Abstract
The purpose of this study was to investigate both the internal consistency and temporal reliability of the Measure of Self-actualization of Potential. Results from the initial pilot study (n = 414) used to develop the inventory are compared with those of a new sample (n = 156) designed to evaluate its stability. Responses from the new sample support our initial findings of moderate to relatively high alpha coefficients for the two main scales and five subscales. Test-retest reliability for the new set of responses indicates high stability, with intraclass correlation coefficients ranging from .74 to .88. For the over-all scale, Cronbach alpha reaches .90 and the intraclass coefficient .87. In addition to better psychometric properties, the new inventory has two other advantages over the Personal Orientation Inventory, fewer items and a self-report format.
