Psychometric properties of the Chinese version of the End-of-Life Decision-Making and Staff Stress Questionnaire / Propiedades psicométricas de la versión china del End-of-Life Decision Making and Associated Staff Stress Questionnaire

ABSTRACT

BACKGROUND/OBJECTIVE: The goal of this study is to establish a Chinese version of the End-of-Life Decision Making and Associated Staff Stress Questionnaire to assess its reliability and validity. METHOD: A sample of 119 Intensive Care Unit physicians and 485 nurses in China completed the questionnaire, along with questionnaires assessing motional exhaustion subscale, Stress Overload Scale, and other variables associated with end-of-life decision. RESULTS: Seven factors obtained via exploratory factor analysis could explain 70.61% of the total variance. Confirmatory factor analysis demonstrated an acceptable model fit with Root Mean Square Error of Approximation (RMSEA) being .078 and Standardized Root Mean Square Residual (SRMR) being .066. Validity evidence based on relationships with other variables was provided by positive or negative correlations between the questionnaire subscales and emotional exhaustion, stress overload, and other variables associated with end-of-life decision. The average content validity index was .96. The Cronbach's Alpha and test–retest reliability was outstanding. CONCLUSIONS: The Chinese version of the End-of-Life Decision Making and Associated Staff Stress Questionnaire is a reliable and valid instrument for measuring the facilitators and hinders to facilitate the end-of-life decision-making, communication and the associated pressure perceived by relevant Intensive Care Unit medical staff among the Chinese population

RESUMEN

ANTECEDENTES/OBJETIVO: El objetivo de este estudio es obtener una versión china del End-of-Life Decision Making and Associated Staff Stress Questionnaire. MÉTODO: Una muestra de 119 médicos de la Unidad de Cuidados Intensivos y 485 enfermeras chinas completaron el cuestionario, junto con cuestionarios para evaluar el agotamiento por movimiento, la sobrecarga de estrés y otras variables asociadas con la decisión del final del la vida. RESULTADOS: Siete factores obtenidos a través del análisis factorial exploratorio explican el 70,61% de la varianza total. El análisis factorial confirmatorio mostró un modelo de cuatro factores con ajuste satisfactorio (RMSEA = .078; SRMR = .066). Las evidencias de validez basadas en las relaciones con otras variables fue demostrada por correlaciones con agotamiento emocional, sobrecarga de estrés y otras variables asociadas con la decisión de fin de la vida. El índice de validez de contenido promedio fue de 0,96. Los coeficientes de fiabilidad de consistencia interna y test-retest fueron buenos. CONCLUSIONES: Se trata de un instrumento que aporta medidas fiables y válidas para la percepción del fin de la vida por el personal médico chino de las unidades de cuidados intensivos
