          Abstract

          Abstract: 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 (M age = 52.97; SD ag = 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.

          Resumen: La pérdida de gratificaciones, como resultado de la enfermedad y tratamiento oncológico, se relaciona con problemas emocionales en supervivientes. Environmental Reward Observation Scale (EROS) es una escala para evaluar reforzamiento ambiental, desarrollada a partir de modelos 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 (M edad = 52.97; DT edad = 7.50) completaron medidas de reforzamiento ambiental, 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 ansiedad 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 hospital anxiety and depression scale.

          A self-assessment scale has been developed and found to be a reliable instrument for detecting states of depression and anxiety in the setting of an hospital medical outpatient clinic. The anxiety and depressive subscales are also valid measures of severity of the emotional disorder. It is suggested that the introduction of the scales into general hospital practice would facilitate the large task of detection and management of emotional disorder in patients under investigation and treatment in medical and surgical departments.

            Individual-patient monitoring in clinical practice: are available health status surveys adequate?

            Interest has increased in recent years in incorporating health status measures into clinical practice for use at the individual-patient level. We propose six measurement standards for individual-patient applications: (1) practical features, (2) breadth of health measured, (3) depth of health measured, (4) precision for cross-sectional assessment, (5) precision for longitudinal monitoring and (6) validity. We evaluate five health status surveys (Functional Status Questionnaire, Dartmouth COOP Poster Charts, Nottingham Health Profile, Duke Health Profile, and SF-36 Health Survey) that have been proposed for use in clinical practice. We conducted an analytical literature review to evaluate the six measurement standards for individual-patient applications across the five surveys. The most problematic feature of the five surveys was their lack of precision for individual-patient applications. Across all scales, reliability standards for individual assessment and monitoring were not satisfied, and the 95% CIs were very wide. There was little evidence of the validity of the five surveys for screening, diagnosing, or monitoring individual patients. The health status surveys examined in this paper may not be suitable for monitoring the health and treatment status of individual patients. Clinical usefulness of existing measures might be demonstrated as clinical experience is broadened. At this time, however, it seems that new instruments, or adaptation of existing measures and scaling methods, are needed for individual-patient assessment and monitoring.

              Preliminary psychometric properties of the Acceptance and Action Questionnaire-II: a revised measure of psychological inflexibility and experiential avoidance.

              The present research describes the development and psychometric evaluation of a second version of the Acceptance and Action Questionnaire (AAQ-II), which assesses the construct referred to as, variously, acceptance, experiential avoidance, and psychological inflexibility. Results from 2,816 participants across six samples indicate the satisfactory structure, reliability, and validity of this measure. For example, the mean alpha coefficient is .84 (.78-.88), and the 3- and 12-month test-retest reliability is .81 and .79, respectively. Results indicate that AAQ-II scores concurrently, longitudinally, and incrementally predict a range of outcomes, from mental health to work absence rates, that are consistent with its underlying theory. The AAQ-II also demonstrates appropriate discriminant validity. The AAQ-II appears to measure the same concept as the AAQ-I (r=.97) but with better psychometric consistency. Copyright © 2011.
