^*Responses use a 7-point Likert scale to assess how often and how much the item reflected the feelings of the patient with respect to the degree of distress. Lower scores indicate more severe impact on daily functioning or degree of distress.

^**Bivariate correlations adjusted for age and gender.

^†Troublesome scores range from 0–100. Higher scores means symptom more troublesome.
