WCE 2017: Correlation of Stress in Kidney Stone Patients with the Wisconsin Stone Quality of Life Questionnaire
Patients (n = 277) from three academic urology sites across North America were recruited for the study. Patients completed the Perceived Stress Scale (PSS-10), and the Wisconsin Stone Quality of Life (WISQOL) to access stress level and HRQOL, respectively. Descriptive data showed that 80% of patients were white-non-Hispanic, 5% white Hispanic/Spanish/Latino, 11% Asian, and 4% Back/African American. 32% patients had stone composition reported, and 95% of those reports had stone containing calcium. WISQOL total and domain scores and PSS-10 scores were compared. Patients’ stone and symptom statuses were used to compare the WISQOL and PSS-10 scores.
Data analysis showed that there was a negative correlation between quality of life and patients’ perceived stress. Analysis on domain-level showed that HRQOL scores in domain 3 (stone-related impact) had a negative correlation with perceived stress (p = 0.002). Based on WISQOL, there was significant difference of HRQOL between patients with and without stones at the time of completing the questionnaires (p < 0.0001). Both WISQOL and PSS-10 could recognize symptomatic and asymptomatic patients (p < 0.0001 and p = 0.001, respectively).
It could be concluded that WISQOL was a stone-specific quality of life measure, while PSS-10 was a non-instrumental measurement. Both questionnaires were able to distinguish symptomatic and asymptomatic patients.
