Abstract
Objective: To assess classical psychometric properties of the Spanish versions of the Bech-Rafaelsen’s mania (MAS) and melancholia (MES) scales. Method: Observational, prospective, and multicentric study in bipolar out-patients. Convergent validity was assessed against the Young Mania Rating Scale and the Montgomery-Åsberg Depression Rating Scale. Discriminant validity, reliability, and sensitivity to change, were also assessed. Results: One hundred and thirteen bipolar patients with a manic episode and 102 bipolar patients with a depressive episode were included. Both the MAS and the MES showed appropriate convergent validity ( r > 0.90), discriminant validity ( P < 0.0001), internal consistency (Cronbach’s alpha >0.80), test–retest reliability [intraclass correlation coefficient (ICC) = 0.69 for the MAS and 0.94 for the MES], inter-rater reliability (ICC > 0.80), and sensitivity to change at 4 weeks since inception ( P < 0.0001; within-group effect size ≥1.8). Conclusion: The Spanish versions of both scales present appropriate psychometric estimates in bipolar patients treated in ambulatory care. [ABSTRACT FROM AUTHOR]
