ABSTRACT
The purpose of this study is to evaluate the factor structure of the Emotional Distress Inventory (EDI), a brief 15 item self report measure of emotional distress in a sample of 238 cancer patients. The conceptual framework that guided the development of the EDI, factor structure, internal consistency, and convergent validity are reported. Emotional distress items were developed and administered to cancer patients who initiated chemotherapy and/or radiation treatments at Morton Plant Hospital Cancer Center in Clearwater, Florida, USA. Item responses were examined y Factor Analyses of Principal Components with promax rotations, which yielded three factors. Strong alpha coefficients and correlations between the EDI, HADS and BSI offer impressive evidence of internal consistency and convergent validity. The EDI presents three subscales that assess Anxiety/Depression, Hopelessness, and Anger Expresion as components of emotional distress. We also discuss the important implications of these subscales, particularly the inclusion of anger expression and hopelessness, in the assessment of emotional distress in cancer patients (AU)
RESUMEN
El propósito de este estudio es evaluar la estructura factorial del Inventario de Distrés Emocional (EDI), un instrumento de medición del distrés emocional de 15 ítems, en una muestra de 238 pacientes con cáncer que iniciaron sus tratamientos de radioterapia y/o quimioterapia en el Hospital Morton Plant en la ciudad de Clearwater, Florida, USA. Se llevó a cabo un análisis factorial exploratorio mediante componentes principales y método de rotación promax con autovalores superiores a 1. El primer factor está configurado por 7 ítems correspondientes a síntomas de ansiedad y depresión. El segundo factor está agrupado por 4 ítems relacionados con sentimientos de desesperanza, mientras un tercer factor presenta 4 ítems que manifiestan la expresión de ira. Los resultados obtenidos nos indican que el Inventario de Distrés Emocional presenta una estructura factorial consistente con el marco conceptual en el cual se báso la construcción del instrumento, como también un elevado nivel de consistencia interna y validez convergente (AU)
