Validation study of the severity of illness scale with a pediatric oncology population
The present investigation evaluated the validity and
reliability of the Severity of Illness Scale (SOIS) with a
pediatric oncology population. The SOIS is a recently
developed measure of illness severity which assesses severity
as defined by degree of impairment, future outlook, quantity
of medical procedures required, number of hospitalizations,
and participation in age appropriate social activities. The
test utility of the SOIS was also investigated in this study.
The SOIS was found to have adequate reliability and validity
for children diagnosed with cancer. Additionally, the SOIS
was rated by physicians and nurse clinicians as a useful
measure of illness severity for the population. Results
suggest the scale evidences high internal consistency, and is
relatively stable over retesting. Interrater reliability
between physicians and nurse clinicians was significant.
Additionally concurrent validity was found to be adequate
with the number of hospitalizations accounting for 25% of the
variance. Convergent and discriminant validity was also
supported. A two-factor structure was found to exist for the
SOIS. Limitations and future research ideas are discussed.
