The Children's PTSD Inventory effectively measures DSM-IV criteria for posttraumatic stress disorder (PTSD) in youth. High reliability and agreement were confirmed through inter-rater and test-retest assessments.

Area of Science:

  • Psychiatry
  • Psychological Assessment
  • Child and Adolescent Mental Health

Background:

  • Posttraumatic stress disorder (PTSD) is a significant mental health concern in children and adolescents.
  • Accurate diagnostic tools are crucial for effective intervention and treatment planning.
  • The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) provides standardized criteria for PTSD diagnosis.

Purpose of the Study:

  • To describe the development and validation of the DSM-IV version of the Children's PTSD Inventory.
  • To assess the psychometric properties of the Children's PTSD Inventory, including reliability and validity.
  • To determine if the inventory accurately captures the DSM-IV criteria for PTSD in a pediatric population.

Main Methods:

  • The Children's PTSD Inventory was developed based on DSM-IV criteria for PTSD.

  • Independent expert judges rated the inventory's comprehensiveness against DSM-IV criteria.
  • The inventory was administered to 82 traumatized and 22 nontraumatized youths at Bellevue Hospital.
  • Psychometric properties, including Cronbach's alpha, inter-rater reliability (kappa and ICC), and test-retest reliability (kappa and ICC), were calculated.

    • Main Results:

    • Independent judges confirmed the inventory measured the intended DSM-IV criteria for PTSD.
    • Internal consistency (Cronbach's alpha) ranged from .53 to .89 at the subtest level and .95 at the diagnostic level.
    • Inter-rater reliability showed high agreement (98.1% at diagnostic level) with excellent kappa (.96) and ICC (.98) at the diagnostic level.
    • Test-retest reliability demonstrated high agreement (97.6% at diagnostic level) with good to excellent kappa (.91) and ICC (.88) at the diagnostic level.

    Conclusions:

    • The DSM-IV version of the Children's PTSD Inventory is a reliable and valid instrument for assessing PTSD in youth.
    • The inventory demonstrates strong psychometric properties, supporting its use in clinical and research settings.
    • The findings support the use of the Children's PTSD Inventory for accurate PTSD diagnosis in accordance with DSM-IV criteria.
