          Abstract

          Abstract Background: The Anxiety Sensitivity Index-3 (ASI-3) is the reference instrument for measuring anxiety sensitivity. The psychometric properties of the Spanish version of the ASI-3 have been examined in university students but not in adults from the general population. Whether the ASI-3 subscales provide relevant information has not yet been examined either. Method: The ASI-3's factor structure, internal consistency, temporal stability, and relationship with neuroticism were examined in a Spanish community sample of 919 adults. Results: In two subsamples of participants, the ASI-3 presented a structure of three correlated factors (physical, cognitive, and social concerns) that loaded on a higher-order factor, but the three factors did not explain much item variance. The total scale and subscales of the ASI-3 showed excellent or good indices of internal consistency (alphas and omegas =.81 -.91), and adequate indices of test-retest reliability at two months (r =.57 -.73) and the relationship with neuroticism and its facets (r =.19 -.52). Conclusions: The ASI-3 provides reliable, valid measures of anxiety sensitivity in Spanish adults, but its subscales are not very useful beyond the information provided by the total scale.

          Resumen Antecedentes: el Índice de Sensibilidad a la Ansiedad-3 (ASI-3) es el instrumento de referencia para medir la sensibilidad a la ansiedad. Las propiedades psicométricas de la versión española del ASI-3 se han examinado en estudiantes universitarios, pero no en adultos de la población general. Tampoco se ha examinado si las subescalas del ASI-3 aportan información relevante. Método: se examinó la estructura factorial del ASI-3, su consistencia interna, estabilidad temporal y relación con neuroticismo en una muestra comunitaria española de 919 adultos. Resultados: en dos submuestras de participantes, el ASI-3 presentó una estructura de tres factores correlacionados (preocupaciones físicas, cognitivas y sociales) que saturaban en un factor de orden superior, pero los tres factores no explicaban mucha varianza de los ítems. La escala total y las subescalas del ASI-3 mostraron índices excelentes o buenos de consistencia interna (alfas y omegas =.81 -.91) y adecuados de fiabilidad test-retest a los dos meses (r =.57 -.73) y de relación con el neuroticismo y sus facetas (r =.19 -.52). Conclusiones: el ASI-3 proporciona medidas fiables y válidas de la sensibilidad a la ansiedad en adultos españoles, pero sus subescalas no son muy útiles más allá de la información proporcionada por su escala total.

          Robust dimensions of anxiety sensitivity: development and initial validation of the Anxiety Sensitivity Index-3.

          Accumulating evidence suggests that anxiety sensitivity (fear of arousal-related sensations) plays an important role in many clinical conditions, particularly anxiety disorders. Research has increasingly focused on how the basic dimensions of anxiety sensitivity are related to various forms of psychopathology. Such work has been hampered because the original measure--the Anxiety Sensitivity Index (ASI)--was not designed to be multidimensional. Subsequently developed multidimensional measures have unstable factor structures or measure only a subset of the most widely replicated factors. Therefore, the authors developed, via factor analysis of responses from U.S. and Canadian nonclinical participants (n=2,361), an 18-item measure, the ASI-3, which assesses the 3 factors best replicated in previous research: Physical, Cognitive, and Social Concerns. Factorial validity of the ASI-3 was supported by confirmatory factor analyses of 6 replication samples, including nonclinical samples from the United States and Canada, France, Mexico, the Netherlands, and Spain (n=4,494) and a clinical sample from the United States and Canada (n=390). The ASI-3 displayed generally good performance on other indices of reliability and validity, along with evidence of improved psychometric properties over the original ASI.

            Evaluating bifactor models: Calculating and interpreting statistical indices.

            Bifactor measurement models are increasingly being applied to personality and psychopathology measures (Reise, 2012). In this work, authors generally have emphasized model fit, and their typical conclusion is that a bifactor model provides a superior fit relative to alternative subordinate models. Often unexplored, however, are important statistical indices that can substantially improve the psychometric analysis of a measure. We provide a review of the particularly valuable statistical indices one can derive from bifactor models. They include omega reliability coefficients, factor determinacy, construct reliability, explained common variance, and percentage of uncontaminated correlations. We describe how these indices can be calculated and used to inform: (a) the quality of unit-weighted total and subscale score composites, as well as factor score estimates, and (b) the specification and quality of a measurement model in structural equation modeling.
