    Research with the M-PULSE Inventory shows that overall approximately 86% (average overall classification accuracy across the 18 Liability areas) of the liability cases could be predicted correctly using M-PULSE Inventory items. The M-PULSE Inventory normative data includes 2,000 cases that are geographically representative and includes data from 44 states within the United States. The M-PULSE Inventory scales are statistically reliable, meaning that there is a high degree of accuracy in the assessment. Cronbach’s alpha is the most common statistic used for assessing reliability. Alpha values above .70 indicate very good reliability, and values above .80 indicate excellent reliability. All M-PULSE Inventory scale reliabilities are above .70 with the vast majority of the alpha values being higher than .80. The M-PULSE Inventory scales are valid since they are strongly related to outcome (i.e. officer misbehavior on the job after being hired).
