“…Regarding evidence of construct validity, the confirmatory factor analysis indicates the unidimensionallity of the scale. This result coincides with those reported by Armento and Hopko (2007) and by other validation studies (Barraca & Pérez-Álvarez, 2010;Valderrama-Díaz et al, 2016;Wagener & Blairy, 2015). It should be noted that, in our study, most of the fit indexes were observed to be below the standard criterion, and only the MIREAL and CFI indexes can be considered appropriate.…”

La pérdida de gratificaciones, como resultado de la enfermedad y tratamiento oncológico, se relaciona con problemas emocionales en su-pervivientes. Environmental Reward Observation Scale (EROS) es una escala para evaluar reforzamiento ambiental, desarrollada a partir de mode-los conductuales que muestran la relación entre reforzamiento ambiental y estado emocional. Este estudio valida esta escala con supervivientes de cáncer de mama y analiza su utilidad para discriminar entre supervivientes con y sin trastornos emocionales. Un total de 219 mujeres supervivientes (Medad = 52.97; DTedad = 7.50) completaron medidas de reforzamiento am-biental, activación y evitación conductual, y estado emocional. Los datos se ajustan a una estructura esencialmente unidimensional, mostrando una consistencia interna elevada y de moderadas a altas con todas las medidas empleadas. Fueron estadísticamente significativas las diferencias en las puntuaciones entre participantes con y sin trastorno emocional. Mediante curvas ROC se estableció el punto de corte óptimo para discriminar ansie-dad y depresión. Aplicando la Teoría de Respuesta al Ítem, se encontró que todos los ítems muestran un poder de discriminación de moderado a alto para evaluar reforzamiento ambiental. La EROS se presenta como una medida fiable y válida que puede emplearse para mejorar la evaluación del estado emocional de supervivientes oncológicos. The loss of rewards resulting from oncological disease has been associated with emotional problems in cancer survivors. The Environmental Reward Observation Scale (EROS) evaluates environmental reinforcement and is based on behavioral models which show the relationship between environmental reinforcement and emotional state. The aim of this study is to analyze the psychometrical properties of this scale in breast cancer survivors and its usefulness in discriminating between survivors with and without emotional disorders. A total of 219 women survivors (Mage= 52.97; SDag= 7.50) completed measures of environmental reinforcement, behavioral activation and avoidance, and emotional state. Data fit an essentially unidimensional structure, showing high internal consistency and correlations, varying from moderate to high, with all the measures used. In the EROS scores, statistically significant differences were found between participants with and without emotional disorders. Optimum cut-off point to discriminate between anxiety and depression was established via Receiver Operating Characteristic curve. Using the framework of the Item Response Theory model, all the items were found to have a power of discrimination for measuring environmental reinforcement ranging from moderate to high. The EROS is a psychometrically sound instrument, which can be used to improve assessment of emotional state in breast cancer survivors.

“…In its original version, with a sample of American students, the scale showed a unifactorial structure with high internal consistency ( α = 0.85) and correlations, from moderate to strong, with different depression scales BDI-II = -0.78; CESD = -0.79; Zung Self-Rating Depression Scale = -0.54. In other validation studies which included the general population and also populations with emotional disorders, carried out with participants who were Spanish ( Barraca and Pérez-Álvarez, 2010 ), Colombian ( Valderrama-Díaz et al, 2016 ), or Belgian ( Wagener and Blairy, 2015 ), in all cases there were found to be appropriate levels of internal consistency and also significant signs of construct validity. Here the Spanish adaptation of the EROS was used ( Barraca and Pérez-Álvarez, 2010 ), for which data is available confirming its reliability ( α = 0.86) and validity (correlations with the BDI-II = -0.73; STAI-E = -0.80; STAI-R = -0.70; BADS-T = -0.69).…”

Activation vs. Experiential Avoidance as a Transdiagnostic Condition of Emotional Distress: An Empirical Study

et al. 2018

View full text Add to dashboard Cite

Background: From a contextual transdiagnostic approach, this study focuses on the importance of the processes of Experiential Avoidance and Activation in explaining and treating psychological problems. There exists widespread empirical evidence to suggest that the response pattern known as Experiential Avoidance, a general unwillingness to remain in contact with particular private experiences through the use of maladaptive avoidance strategies, acts as a functional dimension in various psychological problems. Activation, that is, maintaining contact with experiences/conditions of life and consequently with associated sources of reward, is a condition present in most therapeutic processes. Although a great deal of research has analyzed the relationship of the value of reward with the etiology and maintenance of psychological problems, Activation, as a transdiagnostic factor, has been studied less. The aim of this paper is to carry out an empirical study of the relationship between Activation, EA and emotional state and analyze the capacity of these two conditions to discriminate the intensity and symptomatology type in subjects with emotional distress.Methods: The Hospital Anxiety and Depression Scale (HADS), Environmental Reward Observation Scale (EROS) and Behavioral Activation for Depression Scale (BADS) were completed by 240 health center users.Results: Of the participants, 55% showed clinically relevant emotional distress. All cases of depression showed clinical anxiety. To discriminate between subjects without (n = 109) and with emotional distress (n = 131), analyses of the ROC curves and logistic regression analysis identified the BADS-Avoidance/Rumination followed by the EROS. To discriminate between subjects with anxiety but without depression (n = 61) and with anxiety and depression (n = 70), the most efficient scales were EROS followed by BADS-Social Impairment.Conclusion: It was shown that people with no emotional complaints maintained greater contact with life experiences and with environmental sources of reward than those with emotional distress. Response patterns showing Experiential Avoidance and a reduction in Activation responses were associated with clinical distress. A reduction in Activation was the condition which distinguished those people with the greatest distress and also the greatest comorbidity of symptoms of depression and anxiety. These data support the transdiagnostic nature of Activation and suggest greater attention should be paid to this concept.

El Tratamiento Breve de Activación Conductual para Depresión (BATD-R) orienta actividades reforzantes para intervenir sintomatología depresiva. El objetivo fue establecer el efecto del tratamiento en formato grupal (BATD-G) en una muestra no probabilística de seis hombres exmiembros de la fuerza pública privados de la libertad, con depresión. Se utilizó un estudio de caso único A-B con seguimiento. Los instrumentos fueron la Escala de Observación de Recompensa del Entorno, la Escala de Activación Conductual para Depresión, la Escala de Zung para depresión y los Formatos de monitoreo diario. Se encontró que el BATD-G tuvo efecto en la frecuencia de conductas saludables y depresivas, según las diferencias estadísticamente significativas, entre la línea de base, y tratamiento, así como la estabilidad del cambio en el seguimiento. Al mismo tiempo se encontraron cambios clínicos en las medidas de percepción de reforzamiento medioambiental y factores de cambio de la Activación Conductual (activación, evitación/rumia, afectación laboral/académica y deterioro social). Los tamaños del efecto fueron grandes según el no solapamiento de todos los pares en las conductas depresivas, saludables y estado del ánimo. Se concluyó que la intervención tuvo el efecto esperado en formato grupal para esta población, y fueron coherentes con las teorías de la activación conductual.
