The Hypomania Checklist (HCL-32) : its factorial structure and association to indices of impairment in German and Swedish nonclinical samples

• Background: Bipolar disorders are often not recognized. Several instruments were developed but none primarily focused on hypomania. The Hypomania Checklist (HCL) is aimed at the identification of bipolarity in outpatients. Using a German and Swedish sample, we investigated if the factor structure in nonclinical samples is similar to the one reported for outpatient samples. Furthermore, we tested if people who probably had a lifetime history of hypomania report more depression or other signs of impairment and if current depression is associated with lifetime hypomania.Method: In the German study, participants completed the HCL-32 as an online questionnaire that also included questions about lifetime and current depression (n = 695), whereas the Swedish data relied on the paper-and-pencil version of the HCL-32 completed by a ranclorn sample from a representative population sample (n = 408).Results: The factor structure of the HCL-32 was fairly similar in both samples and to the ones presented by Angst et al (J Affect Disord 2005;88:217-33). People reporting "highs" (>= 4 days and experiencing negative consequences) not only endorsed more HCL-32 symptoms but also had higher rates of current and former depression and psychotherapy. Level of current depression was also associated with lifetime hypomanic symptoms.Discussion and limitation: An "active-elated' and "risk-taking/irritable" factor of hypomania can be distinguished with the HCL-32 in clinical and nonclinical samples. Based on our results, the HCL-32 might even be useful as screening toot in nonclinical samples and not only in depressed outpatients. However, our data do not allow estimating sensitivity and specificity of the HCL-32 because structured clinical interviews were not included.
