multiple linear regression analysis, enter method using all univariate significant independent variables, p‐model distress and somatization <0.001, Adjusted R ² = 0.15 for distress and 0.08 for somatization, variance inflation factor (VIF) for both models <5; CI = 95% confidence interval; p = p‐value; the somatization score was transformed using a natural log‐transformation.
