Development, Content Validity, and Test-Retest Reliability of a Childhood Hydrocephalus Severity Scale

Area of Science:

• Pediatric Neurology
• Medical Scale Development
• Clinical Assessment Tools

Background:

• Childhood hydrocephalus requires accurate severity assessment for effective management.
• Existing assessment methods may lack comprehensiveness or reliability.
• Improved tools are needed to guide treatment and enhance patient care.

Purpose of the Study:

• To develop and validate a reliable, multidomain scale for assessing childhood hydrocephalus severity.
• To enhance clinical communication and decision-making in hydrocephalus management.
• To improve overall patient care for children with hydrocephalus.

Main Methods:

• A modified Delphi technique involving healthcare professionals was used to define scale domains.
• Content validity, internal consistency, and inter-rater reliability were rigorously assessed.
• Anonymous surveys and face-to-face meetings facilitated consensus on scale items.

Main Results:

• The 7-item, 10-point Childhood Hydrocephalus Severity Scale (CHS) was finalized.
• High Content Validity Index (mean I-CVI = 0.91) confirmed item relevance.
• Excellent internal consistency (Cronbach's alpha = 0.988) and inter-rater reliability (ICC = 0.902-0.985) were demonstrated.

Conclusions:

• The CHS is a promising, reliable, and valid tool for assessing childhood hydrocephalus severity.
• The scale can significantly improve communication among healthcare providers.
• Implementation of the CHS has the potential to optimize treatment decisions and patient outcomes.
