QUANTITATIVE RATING OF MANIC STATES.

Abstract

We have investigated Biegel's manic-state rating scale and found the interrater reliability high when the scale was administered both by nurses and psychiatrists. In our study of validation, we tested each item of the scale for calibration, ascending monotonicity and dispersion parallel to a global clinical assessment of the manic state. Six of the scale items were then found valid and those items differed from the valid items in studies of Biegel by including increased social contact. Like Biegel, we found a positive correlation between items concerned with depressed mood, indicating a fluctuation in the mood of manic patients during 8 hours of observation.
