Comparing the screening property of the shortened versions of the Hypomania Checklist-32 (HCL-32): Cross-validation in Korean patients with bipolar disorder and major depressive disorder.J Affect Disord. 2018 02; 227:384-390.JA
To date, shortened versions of the Hypomania Checklist-32 (HCL-32) were proposed to overcome the limitation of a lengthy format; however, a cross-validation study is currently needed to identify which shorter version may function optimally in a clinical sample.
In a Korean patient sample with bipolar disorder (BD) and major depressive disorder (MDD) (BD-I n = 84, BD = II n = 145, MDD n = 285), we examined the reliability and screening property of three shorter versions of the HCL (HCL-20, -16, -8) in comparison with the full HCL-32. Diagnosis was confirmed by the structured clinical interview (SCID-I).
All three shortened HCLs demonstrated a fair screening ability (Area Under the Curve = .72~.74) to discriminate BD patients from MDD patients, which was comparable to that of the HCL-32. When sensitivity and specificity were considered, the HCL-20 showed relatively superior performance among the shortened versions.
The shorter versions were not administered in a 'stand-alone' manner.
This is the first cross-validation study in a large clinical sample with an increased statistical power to compare the screening property of the shortened HCLs. Our results suggest that briefer versions of the HCL could be reliably and economically utilized in clinical and research settings to enhance detection of BD.
