Items from the 40-item Brief Index of Self-actualization were submitted to principal factor analysis with promax and oblique rotation (N = 620). With eigenvalues greater than 1 and factor loadings of .40 or higher, 32 items were retained as four factors, without overlap. A revised Brief Index of Self-actualization is presented as an improved measure of constructs underlying Abraham Maslow's description of a self-actualizing person.
