ABELLO LUQUE, Daniella  and  CORTES PENA, Omar Fernando. Design of multidimensional scale emta affective disorders: psychometric analysis of reliability and validity. Psicol. caribe [online]. 2012, vol.29, n.3, pp.545-591. ISSN 0123-417X.

The purpose of this research was to construct and validate a scale for measuring affective disorders. The sample was taken with 100 students of the Corporación Universidad de la Costa (Barranquilla, Colombia): 81% women and 19% men between 18 and 44 years of age. Initially, the scale contained items from 1 to 57 in the Depression Subscale and items from 58 to 93 in the Mania Subscale. The final scale has items (from 1 to 47) to valuate depressive symptoms and others (from 52 to 80) for mania symptoms. Items from 48 to 51 and from 81 to 85 were made to valuate intensity and chronicity in a more specific way. Statistical data processing came ahead from expected with the SPSS software. Indicating the Cronbach Alpha index obtained in the Depression Subscale, that was equal to (a: 0.942) and in the Mania Subscale was equal to (a: 0.834). In addition, correlated values were estimated from item-scale and a factorial analysis was developed to reach deep in the grade validity of the construct, in order to identify the subjects' level of Mania or Depression. Each subscale valuates low, medium and high ranges. With the Depression Subscale 81% of the sample showed low level results and 19% showed medium level results. With the Mania Subscale at 82% of the sample, showed low level results and 18% showed medium level results, which are consistent with the nature of the original sample from non-clinical approach.
