title: Evaluation of the Psychometric Properties of NOC Outcomes "Anxiety Level" and "Anxiety Self-Control" in a Portuguese Outpatient Sample.
abstract: OBJECTIVE
  To adopt the language and to evaluate the psychometric properties of "Anxiety level" and "Anxiety self-control" NOC outcomes in Portuguese adult patients.
  
  
  METHODS
  Methodological design.
  
  
  RESULTS
  The final European Portuguese version of the NOC outcome "Anxiety level," composed by 16 indicators, proved excellent internal consistency. Exploratory factor analysis (EFA) was forced to three factors. The NOC outcome "Anxiety self-control," composed of nine indicators, demonstrated a questionable internal consistency. EFA was forced to two factors.
  
  
  CONCLUSIONS
  European Portuguese versions of the studied NOC outcomes proved to be tools with acceptable psychometric properties for evaluating anxiety in Portuguese patients.
  
  
  CONCLUSIONS
  This study contributed to the development of NOC language and to the enrichment of nursing's body of knowledge.

  RESULTS
  A versão portuguesa do resultado NOC "Nível de ansiedade", composta por 16 indicadores, apresentou uma excelente consistência interna. A análise fatorial exploratória (AFE) foi forçada a três dimensões. O resultado NOC "Autocontrolo da ansiedade", composto por nove indicadores, apresentou uma consistência interna questionável. A AFE foi forçada a duas dimensões. CONCLUSÕES: As versões portuguesas dos resultados NOC estudados são instrumentos com propriedades psicométricas aceitáveis para avaliar a ansiedade em utentes portugueses. IMPLICAÇÕES PARA A PRÁTICA DE ENFERMAGEM: Este estudo contribuiu para o desenvolvimento da linguagem NOC e para enriquecer o corpo de conhecimento de Enfermagem.
