Abstract
Purpose
To evaluate the test-retest reliability and validity of the Patient Generated Index (PGI) in individuals with Chronic Kidney Disease (CDK) undergoing hemodialysis.
Methods
Through a non-experimental study with repeated measures, PGI was applied twice to assess internal consistency and test-retest reliability. Correlations with the Kidney Disease Quality of Life Short Form (KDQOL-SF), the Human Activity Profile (HAP) questionnaire, the Social Participation Scale, and the Glittre ADL Test were used.
Results
91 individuals with CKD were evaluated. There was high reliability for the PGI (ICC= 0.97) PGI correlated with KQDOL – SF in Functional Capacity r = 0.38 (p < 0.001), Emotional Well-Being r = 0.31 (p = 0.003), Social Aspect r = 0.22 (p = 0.036), Emotional Function r = 0.22 (p = 0.038) and Effect of Kidney Disease r = 0.21 (p = 0.042), and Physical scores r = 0.24 (p = 0.021)), Mental r = 0.21 (p = 0.05) and General r = 0.22 (p = 0.037) summarized. There was a significant correlation between PGI and HAP r = 0.40 (p < 0.001) and the Social Participation Scale r = −0.36 (p < 0.001). There was no correlation between the PGI and Glittre ADL scores r = 0.12 (p = 0.247).
Conclusion
In adults receiving hemodialysis, the PGI proved to be an accurate and reliable instrument for the assessment of the quality of life from the perspective of the patient.
Although hemodialysis treatment is associated with increased survival and symptom control, there is a significant change in the patient’s lifestyle.
In order to provide a more focused view of the individual, the Patient Generated Index (PGI) was created to evaluate the quality of life.
PGI is reliable and correlates with KQDOL – SF and the Social Participation Scale in this population.
