Popis: Objective To assess the sensitivity and specificity of two self-report instruments for detection of bipolarity in a sample of Argentinean patients. Method Spanish versions of the MDQ and the BSDS were administered over four months at 11 sites in Argentina. Diagnoses were made using DSM-IV criteria and the MINI. The study sample consisted of patients diagnosed with Bipolar Disorder (BD) Types I, II, or NOS. BDNOS diagnoses were made using extended guidelines for bipolar spectrum symptoms. Unipolar patients were used as a control group. Of 493 patients screened, 354 completed evaluation by MDQ and MINI, and 363 by BSDS and MINI. Results Specificity of MDQ was 0.97 and BSDS was 0.81. MDQ sensitivity was 0.70 for bipolar type I (BD-I), 0.52 for bipolar II (BD-II) and 0.31 for bipolar not otherwise specified (BDNOS). BSDS sensitivities were 0.75, 0.70 and 0.51 respectively. Limitations This study was performed in specialized outpatient settings and thus its results are not necessarily representative for other clinical settings. There was not a systematic evaluation of comorbid psychiatric disease or test–retest reliability. Conclusion The local versions of the MDQ and the BSDS showed a sensitivity and specificity comparable to previous research. Our results indicate that in this sample, MDQ was more specific for BD and BSDS was more sensitive to detect BD-II and NOS. Since BD-I is more readily recognized than bipolar spectrum disorders, enhanced sensitivity of BSDS for soft bipolarity may be an advantage.
