Person‐reliability indices can assist clinicians in determining the interpretability of a patient's responses to the Basic Personality Inventory (BPI). Using an initial sample of 65 psychiatric patients, we found that: (1) different person‐reliability indices showed modest evidence of psychometric adequacy and tended not to be confounded with general psychopathology; (2) a content consistency index of person reliability was predictably related to other item change variables, whereas within‐session profile stability was related to across‐session measures of profile stability; and (3) evidence for the ability of person‐reliability indices to moderate the validity of clinical criteria was weak. Results provide cautious support for a multidimensional conceptualization of the person reliability construct on the BPI but demand further evaluation of the clinical utility of person‐reliability indices. © 1999 John Wiley & Sons, Inc.
