CARVALHO, Lucas De Francisco  and  SETTE, Catarina Possenti. REVIEW AND VERIFICATION OF THE PSYCHOMETRIC PROPERTIES OF THE MOOD INSTABILITY DIMENSION OF THE DIMENSIONAL CLINICAL PERSONALITY INVENTORY. Act.Colom.Psicol. [online]. 2015, vol.18, n.2, pp.115-127.

The present study aimed to review the Mood Instability dimension of the Dimensional Clinical Personality Inventory (DCPI) and to examine its psychometric properties. To this end, new items were developed that were applied to 230 subjects, aged between 18 and 63 years (M = 23.0, SD = 9.44), with a majority of females (76.4%). All participants answered the DCPI, the Brazilian version of the NEO Personality Inventory-Revised and the Brazilian version of the Personality Inventory for DSM-5 (PID-5). As a result, 306 new items were developed based on four sources of reference in the area and selected by means of content analysis and 27 items to compose the final version of the dimension to be applied. After data collection and statistical analysis, the reviewed dimension was composed of three factors plus a total score. The internal consistency coefficients were adequate and equal to .85 for the final set of 16 items, with a variation range between .78 and .81 per factor. Moreover, the expected intracorrelations were found, as well as consistent correlations with the instruments used. Data allow inferring validity evidence for the scale reviewed, as well as demonstrating satisfactory internal consistency.
