Child psychopathology research is complicated by factors like gender, age, and informant. Adding a quantitative axis to diagnostic systems can help manage these variances and advance developmental psychopathology.

Area of Science:

  • Developmental Psychology
  • Psychiatry
  • Genomics
  • Neuroscience

Background:

  • Child psychopathology is influenced by multiple variance sources, including gender, informant, and age.
  • These factors complicate research and clinical management of psychological disorders.

Purpose of the Study:

  • To discuss how variance sources complicate psychopathology research and clinical management.
  • To propose the inclusion of a quantitative axis in diagnostic systems to account for these variances.
  • To highlight the need for a diagnostic system that controls for variance to advance developmental psychopathology.

Main Methods:

  • Literature review and theoretical discussion.
  • Analysis of variance sources in child psychopathology.

  • Case example using Conduct Disorder to illustrate dimensional approach.

    • Main Results:

    • Gender, informant, and age differences significantly complicate the expression and study of psychopathology.
    • A quantitative axis in diagnostic systems could better account for these variances.
    • Dimensional information, as seen in Conduct Disorder, allows for assessment of pathology severity.

    Conclusions:

    • The current diagnostic system would benefit from a quantitative axis to manage sources of variance.
    • Genomics and neuroscience advancements require a diagnostic system that controls for variance.
    • Dimensionalizing aspects of the Diagnostic and Statistical Manual of Mental Disorders (DSM) is warranted.
