This study investigated the reliability and validity of the Paranoia scale, which was developed for measuring paranoid tendency. It was composed of 20 self-report items from MMPI. The Paranoia scale was administered to 447 college students and 42 psychiatric patients. Among them 187 college students and psychiatric patients were asked to complete the MMPI-Pa scale and the SCL-90-R-PAR scale as well as the Paranoia scale. Results indicated that the Paranoia scale has sufficient reliability and validity. Item-total correlations, α-coefficients, test-retest reliability, inter-item correlations, and all correlations between the paranoid measures were respectably high and significant. And the results of factor analysis suggested single factor. The usefulness of the scale, limitations, and implications for future study were discussed.
