Symptoms linked to distress
The pre- and post-study questionnaires contained the combined PHQ-9
patient health questionnaire and GAD-7 general anxiety disorder
questionnaire, jointly used to measure distress, using symptoms linked
to depression and anxiety. [7, 8]
Table 2 shows the results. For all symptoms evaluated, there was an
improvement in the average rating at the end of the study in comparison
with ratings at the start. In 9 cases the change is statistically
significant.
