Area of Science:

  • Child and Adolescent Psychiatry
  • Health Services Research
  • Psychometrics

Background:

  • Accurate child psychopathology assessment is crucial for early intervention in primary care.
  • Brief primary care visits necessitate efficient screening tools to avoid patient and staff burden.
  • Traditional short-form screening can reduce accuracy; adaptive testing offers an alternative.

Purpose of the Study:

  • To evaluate the accuracy and efficiency of a multidimensional adaptive testing approach for child mental health screening.
  • To simulate an adaptive version of the Pediatric Symptom Checklist (PSC) and compare its performance to the full and short-form versions.

Main Methods:

  • Developed a computerized adaptive version of the Pediatric Symptom Checklist (PSC) using half of a large dataset.

  • Conducted a simulation using independent data (21,150 children) to assess the adaptive PSC's ability to reproduce full PSC results.
  • Utilized factor analysis to identify four latent psychosocial problem dimensions: internalizing, externalizing, attention, and school problems.

    • Main Results:

    • The simulated adaptive PSC (Adaptive PSC) identified four key psychosocial dimensions.
    • The Adaptive PSC required an average of 11.6 questions, with 49% of participants receiving five or fewer.
    • High agreement was found between the Adaptive PSC and the full PSC (1.3% discordant decisions, kappa = 0.93), outperforming a comparable short-form PSC.

    Conclusions:

    • Multidimensional adaptive testing demonstrates potential as an accurate and efficient method for child mental health screening in primary care.
    • This technology can facilitate early identification of mental health issues without overburdening clinical settings.
    • Adaptive testing offers a promising solution for balancing efficiency and accuracy in pediatric screening.
