title: The current status of theory evaluation in nursing.
abstract: OBJECTIVE
  To identify the current status of theory evaluation in nursing and provide directions for theory evaluation for future development of theoretical bases of nursing discipline.
  
  
  BACKGROUND
  Theory evaluation is an essential component in development of nursing knowledge, which is a critical element in development of nursing discipline. Despite earlier significant efforts for theory evaluation in nursing, a recent decline in the number of theory evaluation articles was noted and there have been few updates on theory evaluation in nursing.
  
  
  METHODS
  Discussion paper.
  
  
  METHODS
  A total of 58 articles published from 2003-2014 were retrieved through searches using the PUBMED, PsyInfo and CINAHL. The articles were sorted by the area of evaluation and analysed to identify themes reflecting the theory evaluation process.
  
  
  CONCLUSIONS
  Diverse ways of theory evaluation need to be continuously used in future theory evaluation efforts.
  
  
  CONCLUSIONS
  Six themes reflecting the theory evaluation process were identified: (a) rarely using existing theory evaluation criteria; (b) evaluating specifics; (c) using various statistical analysis methods; (d) developing instruments; (e) adopting in practice and education; and (f) evaluating mainly middle-range theories and situation-specific theories.
