title: Commentary on: Are we overpathologizing everyday life? A tenable blueprint for behavioral addiction research. Excessive behaviors are not necessarily addictive behaviors.
abstract: OBJECTIVE
  The commentary aims to provide clarity to the article "Are we overpathologizing everyday life? A tenable blueprint for behavioral addiction research."
  
  
  METHODS
  We provide another viewpoint for the important issues of behavior addiction.
  
  
  RESULTS
  The course of behavior addiction should be further studied. The criteria of withdrawal and tolerance of behavior addiction are ill-defined and need to be further evaluated.
  
  
  CONCLUSIONS
  The etiology, course, presentation, and functional impairment of behavior addiction should be validated by evidence-based data before being defined as a disorder.
