Summary

The PedsQL Present Functioning Visual Analogue Scales (PedsQL VAS) show reliable measurement of child functioning. Patient and parent agreement improved over time, supporting its use in pediatric healthcare.

Area of Science:

  • Pediatric Psychology
  • Health Outcomes Measurement
  • Ecological Momentary Assessment

Background:

  • The PedsQL Present Functioning Visual Analogue Scales (PedsQL VAS) are designed for rapid, at-the-moment assessment of child and adolescent functioning.
  • This instrument utilizes visual analogue scales for self-report and parent-proxy report of emotional distress and physical symptoms.

Purpose of the Study:

  • To evaluate the reliability and validity of the PedsQL VAS in a pediatric hospital setting.
  • To assess correlations between emotional distress, fatigue, and pain measures.
  • To examine changes in patient-parent concordance over a two-hour period.

Main Methods:

  • Administered the six-item PedsQL VAS to 70 pediatric patients (ages 5-17) and their parents at two time points (T1 and T2).

Related Experiment Videos

  • Hypothesized moderate to large effect size correlations between PedsQL VAS Emotional Distress Summary Score/Fatigue VAS and the Pediatric Pain Questionnaire (PPQ) Pain Intensity VAS.
  • Hypothesized increased patient-parent concordance over time.

    • Main Results:

    • Demonstrated strong test-retest reliability (large effect size) and internal consistency for PedsQL VAS Total Symptom Score and Emotional Distress Summary Score (alphas ranging from .72 to .84).
    • Confirmed significant medium to large effect size correlations between Emotional Distress Summary Score/Fatigue VAS and PPQ Pain VAS.
    • Observed an increase in patient-parent concordance from T1 to T2.

    Conclusions:

    • The PedsQL Present Functioning VAS demonstrates preliminary reliability and construct validity for pediatric self- and parent-proxy reports.
    • Further research is needed to validate the instrument in diverse pediatric settings.
    • The PedsQL VAS shows promise as an ecological momentary assessment tool for pediatric populations.
