Conversion from raw scores to BR scores is relatively complex, and its derivation is based largely on the characteristics of a sample of 235 psychiatric patients, from which developers obtained MCMI profiles and clinician ratings of the examinees’ level of functioning and diagnosis. The median raw score for each scale within this sample was assigned a BR score of 60, and BR scores of 75 and 85 were assigned to raw score values that corresponded to the base rates of presence and prominence within the sample, respectively, of the condition represented by each scale. Intermediate values were interpolated between the anchor scores.
