      Kaliebe's letter to the editor expressed concern about my article “The Postmodern Stress Disorder: A Possible New Disorder”
      • Eiser A.R.
      Postmodern stress disorder (PMSD): a possible new disorder.
      for naming a possible new disorder regarding the phenomenon of violent digital media influences on human behavior. A name is an important part of any scientific discussion as well as any public policy debate, and even the title of the article indicates the theoretical nature of the term I coined. It will certainly not be codified in a future Diagnostic and Statistical Manual of Mental Disorders without further research and verification.
      The recommendation I made that public policy be changed so that a history of digital media usage be part of forensic practice is far from a reality today, so I cannot conceive of Kaliebe's concern that attention to media impact will be overemphasized. Other than in research circles, it has been largely ignored in the debate about mass violence.
      Kaliebe's reference note #4 makes important observations about the impact of video game usage.

      A longitudinal study of risk-glorifying video games and behavioral deviance.
      The authors noted, “playing mature rated, risk glorifying videogames was associated with increases in all measures of behavioral deviance” that included aggressive behavior, delinquent behavior, and increased alcohol consumption in this study with 4-year follow-up.

      So the adverse impact of such game usage extends beyond those who commit mass murder. The Postmodern Stress Disorder most likely represents a spectrum of aberrant behavior.
      There should be heightened concern and an impetus for further research and serious consideration of changes in public policy regarding these products from a public health perspective.
      I thoroughly concur with Kaliebe's advice that media usage should be chosen carefully and its use limited, and thank him for his interest in the matter.

          We thank Eiser1 for raising the issue of media violence and its potential deleterious effects. Eiser argues for a newly defined diagnosis—Postmodern Stress Disorder—to categorize individuals whose violent acts result from media exposure.
