Study on Effect of PSS⁃4 on Rapid Assessment of Stress in Patients With Functional Dyspepsia / 胃肠病学

ABSTRACT

Background: Patients with functional dyspepsia (FD) are accompanied by different degree of psychological stress, and clinicians usually have insufficient quantitative assessment of patients’psychological stress. Aims: To explore the effect of psychological stress assessed by 4-item perceived stress scale (PSS-4) and 10-item perceived stress scale (PSS-10) on dyspepsia symptoms, anxiety, depression, somatization and quality of life in FD patients. Methods: A total of 357 FD patients met Rome IV criteria from March 2021 to March 2022 at Affiliated Hospital of North Sichuan Medical College were recruited. Score of PSS-4, PSS-10, generalized anxiety disorder-7 (GAD-7), patient healthy questionnaire-9 (PHQ-9), adapted patient healthy questionnaire-15 (adapted PHQ-15), dyspepsia symptom severity (DSS), Nepean dyspepsia index-short form (NDI) were performed. Effects of PSS-4, PSS-10 on dyspepsia symptoms, anxiety, depression, somatization and quality of life in FD patients were analyzed. Results: Correlation analysis showed that PSS-4 (r=0.152, P=0.004) and PSS-10 (r=0.194, P=0.000) were correlated with DSS; PSS-4 (r=0.341, P=0.000) and PSS-10 (r=0.389, P=0.000) were correlated with adapted PHQ-15; PSS-4 (r=0.239, P=0.000) and PSS-10 (r=0.327, P=0.000) were correlated with NDI; PSS-4 (r= 0.561, P=0.000) and PSS-10 (r=0.680, P=0.000) were correlated with anxiety; PSS-4 (r=0.449, P=0.000) and PSS-10 (r= 0.524, P=0.000) were correlated with depression. Multiple linear regression analysis showed that psychological stress assessed by PSS-4 (β=0.180, P=0.000), DSS (β=0.390, P=0.000) and FD classification (β=-0.116, P=0.024) were the influencing factors of NDI, and the psychological stress assessed by PSS-10 (β=0.268, P=0.000), DSS (β=0.360, P=0.000) and FD classification (β=-0.116, P=0.021) were the influencing factors of NDI. Conclusions: Psychological stress assessed by PSS-4, PSS-10 have effects on anxiety, depression, somatization, DSS and NDI in FD patients, and PSS-4 is shorter. These results suggest that PSS-4 can be used clinically to assess quickly and initially the impact of psychological stress on FD patients.
