This study investigated whether clinical judgments based on the MMPI-168 are comparable to those based on the standard MMPI. Each of 15 pairs of clinical psychologists were given a combination of short and standard form profiles from three psychiatric patients and asked both to complete an 18-item symptom rating scale for each patient and to decide upon each patient's diagnosis. Analyses of symptom ratings, with one exception, yielded non-significant P ratios and, diagnostic choices did not vary significantly as a function of MMPI form (short vs long) interpreted. Implications of these findings are discussed in terms of the clinical use of the MMPI-168.
