An attempt to develop a locus of control scale that would differentiate one's sense of control over events that are highly controllable from one's sense of control over events that are typically uncontrollable by the individual is described. It was hypothesized that the more remote events are from one's personal control (e.g., events in the lives of others, acts of nature, international events), the greater the likelihood that perceived control over the events will be non-adaptive. This study attempted to identify conceptual and quantitative clusters within the newly designed scale and to relate scores on these clusters to scores on the internal/external dimension of Rotter's Internal/External (I/E) scale. An attempt was also made to evaluate the convergent and divergent validity of the conceptual and quantitative clusters by assessing predicted relationships between these clusters and other physical and psychological measures included in a large test battery. Focus was on determining what clusters of events best differentiate adaptive from non-adaptive internality. The original 72-item scale and several established inventories, including the Rotter I/E scale, were given to approximately 930 students at the University of Tennessee (Knoxville), Pellissippi State Technical Community College, and Carson-Newman College (Jefferson City). Confirmatory and exploratory factor analyses were conducted on subject responses. After the factor analysis process, 34 items were retained in the scale. Several correlations between the factors of the revised instrument and other indicators of health showed that the perception of non-adaptive control was related to higher perceived stress. A table represents the rotated factor pattern. (SLD)
