Full Definition
The Young Mania Rating Scale is an 11-item clinician-administered assessment tool designed to measure the severity of manic episodes in patients with bipolar disorder. Each item is rated on a scale from 0-4 or 0-8, with a total possible score of 60. The scale evaluates elevated mood, increased motor activity, sexual interest, sleep patterns, irritability, speech rate, language-thought disorder, thought content, disruptive-aggressive behavior, appearance, and insight. YMRS scores ≥20 typically indicate a manic episode, while scores <12 suggest remission.
