The purpose of this study was to develop a new locus of control scale other than "Rotter's Internal-External Locus of Control Schedule" for Turkish samples. Various items from some major locus of control scales, most of them with some partial change, were collected and a pool of 80 items containing almost all possible control areas were obtained This item-pool were administred to a college sample of 272 participants (173 females, 99 males). On the basis of item analysis, including item-total correlations and comparison of extreme groups, a resulting 47 item Locus of Control Scale (LCS) were obtained and administred to a new college sample of 111 participants (87 females, 24 males). A subsample of the second sample has also received the Rotter's I-E scale, the Rosenbaum's Learned Resourcefulness Schedule, the SCL-90-R, and the Paranormal Beliefs Scale. Results, based on item analysis, pearson correlations, and factor analysis, showed that the LCS was a reliable and valid instrument, and it has a more simple factor structure than previous Turkish form of the Rotter's I-E Scale. As expected from the literature, positive correlations were obtained between external locus of control and symptomatology, paranormal beliefs and a low level of coping skills. Reliability, validity, and easy of use of the LCS especially in Turkish college samples were discussed.
