Young Mania Rating Scale (YMRS; Young et al., 1978). The YMRS is an 11-item clinician-report measure assessing manic symptoms in adults. The YMRS is can be used as a screening tool (Young et al., 1978), and to monitor symptom changes over time (McIntyre, Mancini, Srinivasan, McCann, Konarski, & Kennedy, 2004). Four of the YMRS items are rated on a zero to eight scale, with the remaining seven being rated on a zero to four scale. This measure can be administered in 10-20 minutes. The YMRS is not intended for diagnosis of mania - if a client scores high, clinicians are encouraged to use a more thorough assessment (Young et al., 1978). The clinician version of the YMRS demonstrates excellent inter-rater reliability ( r = .93) and correlates with the number of subsequent days in the hospital ( r= .66, p<0.001; Young et al., 1978). The measure does not assess comorbid depressive symptoms and should be administered with a depression rating scale (Collaborative Research Team to Study P
