title: Validity and reliability of the Turkish version of the Hill-Bone compliance to high blood pressure therapy scale for use in primary health care settings.
abstract: OBJECTIVE
  To assess the validity and reliability of the Turkish version of the Hill-Bone compliance to high blood pressure therapy scale for use in primary care in Turkey.
  
  
  METHODS
  To develop a Turkish version of the scale, it was translated into Turkish then back-translated into English. The final version was used in a survey in two urban primary health care centers in Izmir, Turkey. For assessing the validity of Turkish scale, we performed factor analysis to test construct validity. Reliability was assessed by calculating the Cronbach's alpha as a measure of internal consistency.
  
  
  RESULTS
  Factor analysis revealed a three-factor structure representing unintentional medication non-adherence; intentional medication non-adherence; and salt intake adherence. Percentages of explained variance were 33.3%, 14.6% and 11.2% respectively. When forcing a two-factor structure we found salt intake and medication adherence clusters. Cronbach's alpha was 0.72 and 0.83 for medication adherence and whole scale, respectively.
  
  
  CONCLUSIONS
  The Turkish Hill-Bone scale presented a factor structure consistent with the original scale, had a high level of internal consistency. It can be used for assessing hypertension patients' compliance in Turkish primary care settings.
