The effect of an information brochure on patients undergoing gastrointestinal endoscopy: a randomized controlled...

The aim of the present study was to test the potential beneficial effects of an information brochure on undergoing a gastrointestinal endoscopy for the first time. The information provided was based on self-regulation theory, and patients could restrict themselves to reading the summary only.

Patients were randomly assigned to an experimental group receiving the brochure at least 1 day before the gastroscopy (N=47), or to a control group not receiving the brochure (N=48).

The results show that all experimental subjects, except one, fully read the brochure. Those receiving the brochure experienced less anxiety before the gastroscopy and, afterwards, they reported greater satisfaction with the preparation for it. With regard to coping style there were some small moderating effects into the direction expected: low blunters (those not seeking distraction under impending threat) as compared to high blunters showed extra reduced anxiety after reading the brochure. They also tended to read the brochure more often. High monitors (those seeking information under impending threat) receiving the brochure showed reduced anxiety during the gastroscopy as compared to low monitors (tendency).

We conclude that providing patients with the developed brochure constitutes an efficient, beneficial intervention.

The brochure could easily be implemented in standard practice without the necessity to take the patient's coping style into account.
