Insights
The Atopic Dermatitis Quickscore (ADQ) is a valid, parent-administered tool for assessing pediatric atopic dermatitis severity at home. It correlates well with the SCORAD and is responsive to treatment changes.
Area of Science:
- Dermatology
- Pediatrics
- Clinical Assessment
Background:
- Current atopic dermatitis (AD) severity scoring systems are complex for parent use.
- A need exists for a simple, home-based tool for monitoring pediatric AD.
- Parental assessment is crucial for ongoing treatment evaluation.
Purpose of the Study:
- To validate the Atopic Dermatitis Quickscore (ADQ) against the established Scoring Atopic Dermatitis Severity Index (SCORAD).
- To assess the responsiveness of the ADQ to changes in AD severity.
- To establish the ADQ as a reliable tool for parent-administered AD assessment.
Main Methods:
- The ADQ, assessing involvement and pruritus of 7 body parts, was developed for parent report.
- Sixty-eight children with moderate to severe AD were assessed using both ADQ (parent) and SCORAD (physician assistant) at admission.
- Pearson correlations were used to compare ADQ and SCORAD scores.
Main Results:
- The ADQ total score showed a strong correlation with the SCORAD total score (r = 0.64, P < .001).
- ADQ pruritus scores also correlated significantly with SCORAD pruritus scores (r = 0.62, P < .001).
- Both scales demonstrated responsiveness to treatment, with significant decreases in scores observed.
Conclusions:
- The parent-administered ADQ is a valid tool for assessing pediatric atopic dermatitis.
- The ADQ is well-correlated with the SCORAD and responsive to clinical changes.
- The ADQ offers a quick (5-minute completion time) and effective method for home-based AD monitoring.
Background:
Atopic dermatitis (AD) severity is assessed using relatively elaborate scoring systems administered by health care practitioners; modification for parent assessment or self-assessment is limited. For ongoing home-based evaluation of pediatric AD treatment and outcomes, a quick, easy-to-use, parent-administered scoring tool is essential.
Objective:
To evaluate the validity and responsiveness to change of the Atopic Dermatitis Quickscore (ADQ) compared with the established, widely used Scoring Atopic Dermatitis Severity Index (SCORAD).
Methods:
The ADQ was developed for parent report and was validated against the SCORAD. The SCORAD assesses percentage of body surface area involved, intensity of a "representative area," pruritus, and insomnia. The ADQ assesses involvement and pruritus of 7 body parts. Sixty-eight children entering a pediatric day treatment program for moderate to severe AD were recruited. Skin severity was scored at admission by a physician assistant using the SCORAD and by a parent using the ADQ. Pearson correlations of the 2 scales were assessed.
Results:
The ADQ total score correlates with the SCORAD total score (r = 0.64, P < .001). The ADQ pruritus score correlates with the SCORAD pruritus score (r = 0.62, P < .001). Correlation at the end of treatment was also seen for ADQ and SCORAD total and pruritus scores (r = 0.39, P = .02, and r = 0.66, P < .001, respectively). Responsiveness of both scales to change in skin condition was demonstrated, with significant decreases in total and pruritus scores (P < .001).
Conclusions:
The parent-administered ADQ takes 5 minutes to complete. Scores from the ADQ and the SCORAD are well correlated and are responsive to changes in skin condition, supporting the validity of the ADQ.
