title: Moving from the quality of life concept to a theory.
abstract: BACKGROUND
  The Special Interest Quality of Life Group has updated its set of statements defining the quality of life (QOL) construct to reflect emerging areas of agreement and the framework for understanding better the QOL construct.
  
  
  METHODS
  This article examines the major areas currently under discussion involving the objective-subjective dichotomy, needs, and core domains.
  
  
  RESULTS
  It is concluded that while the new statements constitute a significant advance, further progress requires testable theory. In order to facilitate such future research, a conceptual model is proposed that distinguishes causal and indicator variables within the framework of a homeostatic management system.
  
  
  CONCLUSIONS
  Several lines of empirical investigation are suggested to test this and similar theoretical models with a view to taking our conceptualization of QOL to the next level.
