What is the specificity of the HCL-32?

The samples reported similar clinical profiles and the structure for the HCL-32 demonstrated two main factors identified as “active/elated” hypomania and “risk-taking/irritable” hypomania. The HCL-32 distinguished between BP and MDD with a sensitivity of 80% and a specificity of 51%.

Which is the best cut off for HCL-32?

The HCL-32 distinguished between BP-II and UP, with 13 being the optimal cut-off. A cut-off of 13 yielded a sensitivity of 0.77 and a specificity of 0.62 between BP and UP. This study demonstrated that the simplified Chinese version of HCL-32 was valid for patients with mood disorders.

Is there a Chinese version of the HCL-32?

The 32-item Hypomania Checklist (HCL-32), a questionnaire for screening bipolar disorders, has been utilised in several countries, but it unclear if the Chinese version of the HCL-32 is valid. Consecutive patients with bipolar disorders (BP, N = 300) and unipolar major depression (UP, N = 156) completed the Chinese version of the HCL-32.

Is the HCL-32 a sensitive instrument for hypomanic symptoms?

Although the HCL-32 is a sensitive instrument for hypomanic symptoms, it does not distinguish between BP-I and BP-II disorders. Future studies should test if different combinations of items, possibly recording the consequences of hypomania, can distinguish between these BP subtypes.
