Validade de conteúdo de versão resumida da subescala do Inventário de Ansiedade Traço-Estado (IDATE)

The goal was to describe the content validity of a short version of the state subscale of Spielberger's "State-Trait Anxiety Inventory (STAI)", based on the original version adapted to Spanish, in Spanish patients receiving invasive mechanical ventilation (IMV). The sample consisted of 16 patients receiving IMV at the Alicante Hospital (Spain), who selected the items from the full Spanish version of the STAI-state that were most relevant to them. Items 1, 5, 9, 10, 12 and 20 from the original scale are the most relevant for the Spanish patients receiving IMV and 5 of these are included in the short version of the scale (83.3% agreement). The short scale has shown adequate content validity for Spanish patients receiving IMV.Se tuvo por objetivo describir la validez de contenido de una versión corta de la subescala Estado del State-Trait Anxiety Inventory (STAI) de Spielberger, a partir de la versión original adaptada al español, en pacientes españoles con ventilación mecánica invasora (VMI).

Visual memory dysfunction as a neurocognitive endophenotype in bipolar disorder patients and their unaffected relatives. Evidence from a 5-year follow-up Valencia study

BACKGROUND: Scarce research has focused on Visual Memory (VM) deficits as a possible neurocognitive endophenotype of bipolar disorder (BD). The main aim of this longitudinal, family study with healthy controls was to explore whether VM dysfunction represents a neurocognitive endophenotype of BD. METHODS: Assessment of VM by Rey-Osterrieth Complex Figure Test (ROCF) was carried out on a sample of 317 subjects, including 140 patients with BD, 60 unaffected first-degree relatives (BD-Rel), and 117 genetically-unrelated healthy controls (HC), on three occasions over a 5-year period (T1, T2, and T3). BD-Rel group scores were analyzed only at T1 and T2. RESULTS: Performance of BD patients was significantly worse than the HC group (p < 0.01). Performance of BD-Rel was also significantly different from HC scores at T1 (p < 0.01) and T2 (p?=?0.05), and showed an intermediate profile between the BD and HC groups. Only among BD patients, there were significant differences according to sex, with females performing worse than males (p?=?0.03). Regarding other variables, education represented significant differences only in average scores of BD-Rel group (p?=?0.01). LIMITATIONS: Important attrition in BD-Rel group over time was detected, which precluded analysis at T3. CONCLUSIONS: BD patients show significant deficits in VM that remain stable over time, even after controlling sociodemographic and clinical variables. Unaffected relatives also show stable deficits in VM. Accordingly, the deficit in VM could be considered a potential endophenotype of BD, which in turn may be useful as a predictor of the evolution of the disease. Further studies are needed to confirm these findings.VB-M is supported by the national grant PI16/01770 (PROBILIFE Study), from the ISCIII.

Diagnóstico clínico en psicología a través de redes neurales

Se presenta un sistema experto basado en redes neurales que a partir de las respuestas de pacientes clínicos a un cuestionario de 169 ítems es capaz de llevar a cabo el diagnóstico de nuevos pacientes en relación a si pertenecen a una de las tres grandes patologías clínicas (depresión, esquizofrenia o neurosis), o bien pueden ser diagnosticados como personas mentalmente "sanas". Los análisis estadísticos muestran el poder predictivo de esta herramienta, lo que confirma que tales modelos podrán ser empleadas en un futuro próximo como herramientas de apoyo en la tarea profesional del psicólogo, tal y como ya ocurre en otras ciencias

Forma abreviada de la WAIS-IV: estudio piloto en pacientes con esquizofrenia

The aim of this study is to develop a WAIS-IV short form of the Spanish version for its use with schizophrenia patients, which would allow estimating their intellectual capacity in a short period of time (approximately 30 minutes). The sample was composed by a clinical group consisting of 35 schizophrenia patients and a control group consisting of 35 people with no known history of mental illness. Data demonstrated that the best combination of tests was: Similarities (Verbal comprehension), Visual puzzles (Perceptual reasoning), Arithmetic (Working memory) and Coding (Processing speed). With this short form, it was possible to obtain a linear correlation between the IQ of the full scale and that of the abridged form of 0.941 in the clinical and 0.940 in the control group. For both groups, the differences between the real IQ averages and the estimated ones were not significant. Moreover, the short form is capable of classifying a substantial number of people in the same IQ category than the full scale does
