ABSTRACT

Objective:

to construct and validate an educational booklet on high dose rate gynecological brachytherapy (HDR) for women with gynecologic cancer.

Methods:

a methodological study, with the construction and validity of a booklet based on the Doak, Doak and Root theoretical-methodological framework. Content and appearance validity was guided by the Delphi technique, by 11 judges, selected using Jasper’s criteria. Afterwards, clinical validity was carried out with the target population.

Results:

the booklet, built from evidence from an integrative review, validated with judges, obtained an overall CVI of 0.98. After clinical validity with 27 women, it presents 24 sheets with illustrations produced by a graphic designer, subdivided into topics: gynecological system anatomy and gynecological cancer epidemiology, gynecological brachytherapy definition, therapeutic steps, approach to side effects and management, and two pages for notes.

Conclusions:

the booklet has validity for use in HDR gynecological brachytherapy treatment.

Differentiate information for hysterectomized and non-hysterectomized patients and emphasize the importance of treatment attendance.	Accepted
Add as guidance the use of vaginal showers with chamomile tea.	Not accepted, because no evidence was identified in the scientific literature for the use of such practice. It is noteworthy that this suggestion was given by only one judge.
