Reliability and validity of a Brazilian version of the Hypomania Checklist (HCL-32) compared to the XXXX Questionnaire (MDQ).

@entity1316 @entity162 @entity308 @entity915
OBJECTIVE: @entity162 are often not recognized and undertreated. The diagnosis of current or past episodes of hypomania is of importance in order to increase diagnostic certainty. The Hypomania Checklist-32 is a self-applied questionnaire aimed at recognizing these episodes. As part of the international collaborative effort to develop multi-lingual versions of the Hypomania Checklist-32, we aimed to validate the Brazilian version and to compare its psychometric properties with those of the @entity1316 Questionnaire. METHOD: Adult outpatients with @entity162 I (n=37), @entity162 II (n=44) and @entity308 (n=42) of a specialized @entity1316 unit were diagnosed according to DSM-IV-TR using a modified version of the @entity915 . We analyzed the internal consistency and discriminative ability of the Hypomania Checklist-32 Brazilian version in relation to the @entity1316 Questionnaire. RESULTS: The internal consistency of the Brazilian Hypomania Checklist-32, analyzed using Cronbach's alpha coefficient, was 0.86. A score of 18 or higher in the Hypomania Checklist-32 Brazilian version distinguished between @entity162 and @entity308 , with a sensitivity of 0.75 and a specificity of 0.58, compared to 0.70 and 0.58, respectively, for the @entity1316 Questionnaire (score>7). The Hypomania Checklist-32 Brazilian version showed a dual factor structure characterized by "active/elated" and "risk-taking/irritable" items. Hence, the Hypomania Checklist-32 Brazilian version was found to have a higher sensitivity but the same specificity as the @entity1316 Questionnaire. CONCLUSION: The Brazilian version of the Hypomania Checklist-32 has adequate psychometric properties and helps discriminating @entity162 from @entity308 (but not @entity162 I from @entity162 II) with good sensitivity and specificity indices, similar to those of the @entity1316 Questionnaire.
