An investigation of the Self-Report Manic Inventory as a diagnostic and severity scale for mania.

The initial study on the Self-Report Manic Inventory (SRMI) reported that it reliably diagnosed mania. In the current study, we replicated the initial study on the SRMI. We also evaluated its ability to quantify manic symptomatology and to measure change during inpatient treatment. The findings show that manic patients are capable of reporting their symptoms, regardless of their insight into their condition. They also confirm that the SRMI is a reliable diagnostic instrument and that it performs consistently over time when used with a 1-week time format. The SRMI is also sensitive to clinical improvement in hospitalized patients undergoing treatment. The SRMI correlated well with the Young Mania-Rating Scale (YMRS), which served as an external validator of SRMI scores at the beginning and end of hospitalization. Factor analysis produced two groups of manic subjects who closely resemble the hedonistic euphoric type and the energized dysphoric type initially reported by Shugar et al.
