title: Validation of the Nursing Activities Score in Portuguese intensive care units.
abstract: to describe the process of adaptation and validation of the Nursing Activities Score to the Portuguese context.
  this was a pilot study of adaptation and validation of the Nursing Activities Score with a sample consisting of 67 patients hospitalized in the intensive care units of three Portuguese hospitals. The construct validity was assessed through factor analysis procedures and the internal consistency of the items was measured through the Cronbach's alpha coefficient.
  a mean workload value of 63.04% (SD = 14.25; Median = 61.30) was obtained. Psychometric data revealed a Cronbach's alpha of 0.71 in the total scale, indicating an acceptable accuracy. Confirmatory factor analysis suggested an appropriate adjustment between the model and the data (χ2(199) = 214.5, p = 0.214; CFI = 0.95; RMSA = 0.035).
  in the present study, the Portuguese version of the Nursing Activities Score was found to be a valid instrument, enabling a safe assessment of the workload of nurses.
