Assessment of state and trait anxiety in subjects with anxiety and depressive disorders.
ABSTRACT The State-Trait Anxiety Inventory (STAI) is one of the most widely used scales for the evaluation of anxiety in medical and, to a lesser extent, psychiatric patients. Although there is a relatively large amount of STAI data about anxiety for individuals with a variety of psychiatric disorders, the results of many anxiety studies include only state or trait and many studies have been influenced by comorbidity and by variations in diagnostic criteria used. We studied state and trait anxiety and compared the revised form of the STAI (Form Y) with the original (Form X) to evaluate the anticipated improvement in the measure. In addition, we compared the STAI results with those of another self-report measure (the Symptom Checklist-90 anxiety and depression scales) and also with interviewer-rated measures of anxiety (Hamilton Rating Scale for Anxiety) and depression (Hamilton Rating Scale for Depression). Results indicate that the STAI does not clearly differentiate anxiety disorders from depressive disorders and support the use of multiple tests and of both self-report and interviewer ratings in the evaluation of anxiety and depression in psychiatric patients.

ABSTRACT: Anxiety sensitivity (AS) was modeled as a bifactor in a college-aged sample.•The general factor was associated with negative affect and mood/anxiety symptoms.•AS cognitive concerns was associated with worry and depression.•AS social concerns was associated with all mood/anxiety symptoms.•AS physical concerns was not related to any mood/anxiety symptoms.Personality and Individual Differences 02/2015; 74.

ABSTRACT: Resumen Este estudio tuvo como objetivo investigar la estructura interna del State-Trait Anxiety Inventory (STAI-T) en una muestra de deportistas de Brasil. Participaron 179 sujetos que practicaban cinco deportes diferentes, con edades entre 14 y 58 años (M=21,04; DT=4,21). El inventario evalúa la ansiedad como estado y como rasgo, pero en este estudio fue utilizada apenas la escala referente a los rasgos, compuesta por 20 ítems dispuestos en una escala Likert de cuatro puntos. Los resultados del análisis factorial confirmatorio indicaron que los ítems no se ajustaron adecuadamente al modelo originalmente establecido por el instrumento y, considerando ese resultado, se optó por realizar un análisis factorial exploratorio, el cual mostró la existencia de dos factores que explicaron el 33% de la variancia. Esos factores fueron denominados de ansiedad presente y ansiedad ausente, con coeficientes de precisión con valores de 0,82 y 0,72 respectivamente. Palabras clave: STAI-T, evidencia de validez, deportistas, psicología del deporte, evaluación psicológica. Abstract This study aimed to examine the internal structure of the State-Trait Anxiety Inventory (STAI-T) in a sample of Brazilian athletes. Participants were 179 subjects practicing five different sports modalities, aged between 14 and 58 years (M = 21.04; SD = 4.21). The inventory assesses anxiety as state and trait, but in this study only the trait anxiety scale was used which is composed of 20 items arranged in a four-point Likert scale. Results of the confirmatory factor analysis indicated the items were not properly adjusted to the instrument's original model. This exploratory factor analysis indicated the existence of two factors that explained 33% of the variance. These factors were called present anxiety and absent anxiety, with reliability coefficients of 0.82 and 0.72 respectively.

ABSTRACT: Experimental evidence indicates that enriched environment (EE) induces neurobiological and behavioural alterations. EE in early life improves learning and memory and reduces trait and state anxiety. However, the effect of EE established in adulthood has rarely been investigated. Thus, the aim of this study was to evaluate the possibility of modifying the levels of trait and/or state anxiety of adult rats exposed to EE. Seventy adult Wistar male rats were first tested in the Free-exploratory Paradigm (FEP) and were categorized according to their levels of trait anxiety (high, medium and low). Subsequently, half of the animals from each category returned to their home cages (Standard Condition: SC) and the other half was transferred to an enriched environment (Enriched Condition: EC). After three weeks, all animals were again tested in FEP. Seven to 10 days later, fifty of the seventy animals were tested on the elevated plus-maze test (EPM). In FEP, EE reduced locomotor activity in the second exposition independently of the anxiety category and, it decreased the levels of trait anxiety of highly anxious rats. No effect of EE was observed on EPM. In conclusion EE established in adulthood was able to reduce high trait anxiety, a major risk factor for anxiety disorders.Neuroscience Letters 10/2014; 584.
