Stress-Related Growth Scale-Short Form: a portuguese validation for cancer patients

espanolAntecedentes/Objetivo El cancer puede ser extremadamente disruptivo y transformador al mismo tiempo, provocando altos niveles de angustia que pueden promover la percepcion de cambios positivos en la vida y crecimiento. Este estudio tiene como objetivo analizar las propiedades psicometricas de la Stress-Related Growth Scale-Short Form (SRGS-SF) en pacientes con cancer. Metodo 209 pacientes con cancer heterogeneo en estadio de la enfermedad y diagnostico han completado informacion clinica y sociodemografica, Distress Thermometer, Positive and Negative Affect Schedule, Escala visual-analogica de los cambios de vida positivos percibidos y Stress-Related Growth Scale-Short Form. Resultados El analisis de la estructura interna apunto una estructura unifactorial con indices de ajuste adecuados y una alta fiabilidad (.92) evaluada a traves del coeficiente omega de McDonald. La validez fue proporcionada a traves de la evidencia de correlaciones significativas con otras variables. Conclusiones La version portuguesa del SRGS-SF parece presentar las propiedades psicometricas necesarias para ser considerada una herramienta corta valida y confiable, para evaluar las percepciones de crecimiento despues del cancer y contribuir para intervenciones psico-oncologicas especificas e integradoras. EnglishBackground/Objective Cancer can be extremely disruptive, triggering high levels of distress, and at the same time transformative, promoting perceptions of positive life changes and growth. This study aims to analyze the psychometric proprieties of the Stress-Related Growth Scale Short-Form (SRGS-SF) in cancer patients. Method 209 Cancer patients heterogeneous in disease stage and diagnosis completed: clinical and sociodemographic information, Distress Thermometer, Positive and Negative Affect Schedule, Visual-analogue Scale of Perceived Positive Life Changes, and Stress-Related Growth Scale-Short Form. Results The analysis of internal structure pointed to an one-dimensional scale, with high reliability (.92) measured through the McDonald`s omega coefficient. Validity was also evidenced through significant correlations with other variables. Conclusions The Portuguese version of the SRGS-SF seems to present the necessary psychometric proprieties to be considered a valid and reliable short tool, to assess perceptions of growth following cancer and contribute to targeted and integrative psycho-oncological interventions.
