The HCL-32 is an excellent tool to screen for past episodes of hypomania developed by Jules Angst [45, 46]. It consists of 32 items describing symptoms of hypomania which require a yes/no answer based on whether the participant experienced that symptom. The final score is derived by summing the affirmative answers, and patients with a total score of 13 or higher are identified as having probable bipolar disorder (BD).
