Validation of an educative manual for patients with head and neck cancer submitted to radiation therapy

OBJECTIVE: develop the content and face validation of an educative manual for patients with head and neck cancer submitted to radiation therapy. METHOD: descriptive methodological research. The Theory of Psychometrics was used for the validation process, developed by 15 experts in the theme area of the educative manual and by two language and publicity professionals. A minimum agreement level of 80% was considered to guarantee the validity of the material. RESULTS: the items addressed in the assessment tool of the educative manual were divided in three blocks: objectives, structure and format, and relevance. Only one item, related to the sociocultural level of the target public, obtained an agreement rate <80%, and was reformulated based on the participants' suggestions. All other items were considered appropriate and/or complete appropriate in the three blocks proposed: objectives - 92.38%, structure and form - 89.74%, and relevance - 94.44%. CONCLUSION: the face and content validation of the educative manual proposed were attended to. This can contribute to the understanding of the therapeutic process the head and neck cancer patient is submitted to during the radiation therapy, besides supporting clinical practice through the nursing consultation.
