Summary An inventory of 130 items designed to tap many facets of experienced control was factor analyzed. Eighteen oblique factors were derived. Correlations with other measures included in a six-hour personality battery were consistent with the interpretations assigned to the factors. Three item analyses and another factor analysis were undertaken for the purpose of developing a revised inventory that contains refined and expanded scales for seven factors. The dimensions measured by the revised instrument have been found to be related to intellectual performance, problems of weight control, marijuana usage, and various patterns of psychological dependence.
