Area of Science:

• Pediatric Research
• Psychometrics
• Health Outcomes Measurement

Background:

• Assessing child illness severity from a parent's perspective is crucial for comprehensive care.
• Existing measures may not fully capture the multidimensional nature of illness severity.
• The Multidimensional Illness Severity Questionnaire (MISQ) was developed as a brief, parent-reported tool.

Purpose of the Study:

• To evaluate the reliability and concurrent validity of the Multidimensional Illness Severity Questionnaire (MISQ).
• To establish the MISQ as a dependable measure for assessing childhood illness severity.

Main Methods:

• A cross-sectional survey was conducted with parents of 20 children in a pediatric research study.
• Parents completed the MISQ along with four other established measures of illness severity and general health.
• Internal consistency was assessed using Cronbach's alpha, and concurrent validity was determined through correlational analysis.

Main Results:

• The MISQ demonstrated adequate internal consistency with a Cronbach's alpha of 0.76.
• MISQ scores showed strong correlations with other measures of illness severity, supporting its concurrent validity.
• The measure captured a range of illness severity perceptions among parents.

Conclusions:

• The Multidimensional Illness Severity Questionnaire (MISQ) is a reliable and internally consistent tool.
• The MISQ is a valid measure for assessing parent-reported illness severity in children.
• Its ease of administration makes it a practical option for clinical and research settings.
