          Abstract

          ANTECEDENTES: Pese a ser uno de los instrumentos para evaluar ansiedad más empleados por profesionales de la salud mental, el Cuestionario de Ansiedad Estado-Riesgo (STAI, por sus siglas en inglés) ha sido objeto de críticas, entre las que destaca la posible existencia de un conjunto de reactivos que, por evaluar depresión, conformarían un factor independiente. OBJETIVO: El objetivo de este trabajo es evaluar la factorización del STAI en una muestra de pacientes con diagnóstico de depresión. MÉTODO: Se aplicó la adaptación española del STAI a 266 pacientes españoles diagnosticados con diferentes trastornos depresivos. RESULTADOS: Mediante un análisis factorial exploratorio, se determinaron tres factores subyacentes: ansiedad estado, ansiedad rasgo positiva y ansiedad rasgo negativa. DISCUSIÓN Y CONCLUSIÓN: La factorización realizada no permite confirmar la presencia de conjuntos de reactivos específicos para la depresión, señalada anteriormente como la principal crítica a este cuestionario. Además, los elevados valores del alfa categórico, tanto en la estructura factorial obtenida como en las subescalas teóricas, son indicios de una elevada fiabilidad para el empleo del STAI en pacientes con diagnóstico de depresión.

          BACKGROUND: Despite being one of the questionnaires to assess anxiety more employed by mental health professionals, the State Trait Anxiety Inventory (STAI) has been criticized. The main criticism is that the possible existence of a set of items to assess depression would form an independent factor. OBJECTIVE: The aim of this work is to evaluate the STAI factorization in a sample of patients diagnosed with depression. METHOD: We applied the Spanish adaptation of the STAI to 266 Spanish patients diagnosed with various depressive disorders. RESULTS: Three underlying factors were identified in the exploratory factor analysis: state anxiety, positive trait anxiety and negative trait anxiety. DISCUSSION AND CONCLUSION: The factorization did not confirm the presence of specific item sets for depression, pointed above as the main criticism of this questionnaire. Furthermore, the high values of the categorical alpha, both in the factor structure obtained and the theoretical subscales, are highly reliable indications for the use of the STAI in patients diagnosed with depression.

            Psychometric properties of the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA): comparison to the State-Trait Anxiety Inventory (STAI).

            The State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA; M. J. Ree, C. MacLeod, D. French, & V. Locke, 2000) was designed to assess cognitive and somatic symptoms of anxiety as they pertain to one's mood in the moment (state) and in general (trait). This study extended the previous psychometric findings to a clinical sample and validated the STICSA against a well-published measure of anxiety, the State-Trait Anxiety Inventory (STAI; C. D. Spielberger, 1983). Patients (N=567) at an anxiety disorders clinic were administered a battery of questionnaires. The results of confirmatory factor analyses (Bentler-Bonnett nonnormed fit index, comparative fit index, and Bollen fit index>.90; root-mean-square error of approximation /=.64), the STICSA was more strongly correlated with another measure of anxiety (rs>/=.67) and was less strongly correlated with a measure of depression (rs
