Validity and Reliability of the Edmonton
Symptom Assessment Scale in Turkish
Cancer Patients
ABSTRACT
The Edmonton Symptom Assessment Scale (ESAS)
is simple and easy to use with cancer patients.
This study was planned for the purpose of adapting and
determining the validity and reliability of the ESAS for
Turkish culture. The study was conducted in outpatient
and inpatient chemotherapy units at a university hospital
between December 2004 and February 2005. A total of
113 cancer patients participated in the research. Written
permission to conduct the research was obtained from the
facility and verbal and written consent was obtained from
the patients. Research data were collected using a questionnaire,
the ESAS and the Rotterdam Symptom Checklist
(RSC). In the ESAS validity study, language validity,
content validity and criterion-related validity were tested.
In the reliability study Cronbach?s alpha and item-total
score correlation were calculated. The patients? mean age
was 48.86?13.18. The Pearson product moment correlation
coefficient between the ESAS and RSC scores was
calculated to be r=0.75, p < 0.05. A Cronbach?s alpha coefficient
of 0.77 was determined for the ESAS. The lowest
item-total correlation on the ESAS (r=0.30, p <0.05) was
for item 10 (other, constipation) and the highest (r=0.62,
p <0.05) was for item 1 (pain). The Turkish version of the
ESAS was determined to be a valid and reliable tool for
use in Turkish individuals with cancer. [Turk J Cancer
