Sensitivity and specificity of the mood disorder questionnaire and the bipolar spectrum diagnostic scale in Argentinean patients with mood disorders
Abstract 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. …
Bipolar disorders and affective temperaments: a national family study testing the "endophenotype" and "subaffective" theses using the TEMPS-A Buenos Aires.
The purpose of this study is to examine the prevalence of affective temperaments between clinically unaffected relatives of bipolar patients and secondarily to investigate the impact of these "subaffective" forms on their quality of life (QoL).The study was performed in seven sites across Argentina. We administered the scales TEMPS-A and Quality of Life Index to a sample of 114 non-ill first degree relatives of bipolar disorder patients ("cases") and 115 comparison subjects without family history of affective illness ("controls"). We used The Mood Disorder Questionnaire to rule out clinical bipolarity.Mean scores on all TEMPS-A subscales were significantly higher in cases, except for hypert…
Visuospatial deficits in schizophrenia: central executive and memory subsystems impairments
Object and spatial visual working memory are impaired in schizophrenic patients. It is not clear if the impairments reside in each memory subsystem alone or also in the central executive component that coordinates these processes. In order to elucidate which memory component is impaired, we developed a paradigm with single spatial and object working memory tasks and dual ones with two different delays (5 and 30 s). Fifteen schizophrenic patients and 14 control subjects performed these tests. Schizophrenic patients had a poorer performance compared to normal controls in all tasks and in all time delays. Both schizophrenics and controls performed significantly worse in the object task than in…
