Uji Reliabilitas Instrumen Kualitas Hidup pada Penderita Kanker Payudara Reability Test on The Instrument of Quality of Life For Breast Cancer Patients
Abstrak: Breast cancer can
influence the quality of patient’s life. A measurement of quality of life (QOL)
is important to evaluate the health services and the continuity of patient
life. The Quality of Life Instrument (Quality of Life Breast Cancer Scale) by
Ferrell, et al (1995) which has been translated into Indonesian as The Quality
of Life Breast Cancer Instrument has not been tested its reliability.
Objective: To know the instrument’s reliability and measuring agreement
rating of breast cancer patient’s life quality between two raters.
Method: This was an observational study using a cross-sectional study
design. The subjects were 50 women with stage II-III of breast cancer at
Sardjito Hospital selected using an accidental sampling technique. Data was
collected through interviews using the QOL instrument guideline. Each subject
was interviewed twice by nurse and midwife with 2-14 days difference between
the interviews. The data were analyzed with Univariate, and Bivariate with
Coefficient Kappa analysis, Intraclass Coefficient Correlation analysis, and
alfa Cronbach Coefficient analysis.
Results: The Kappa analysis to 46 items of quality of life questions done
by nurse and midwife resulted in “good” and “very good” category. The lowest
result was k=0.63 and the highest result was k=1.00. The lowest result of
coefficient alpha analysis was r=0.63/0.63 while the highest was r=0.88/0.87.
The lowest intraclass coefficient was r=0.93 while the highest was r=0.99.
Conclusion: The quality of life breast cancer instrument could likely be
adapted for breast cancer patients in Indonesia.
