The Content Validity Ratio (CVR ') was used, by the Tristan method and the content validation index (CVI').

Results: All the items were valid in the 4 criteria measured, so the global and acceptable CVI coincided. The instrument showed clarity, coherence, precision and relevance with CVI figures of 0.90, 0.93, 0.92, and 0.94 respectively.

Conclusions: A valid instrument was developed in content and presentation so it is available to continue with the next stage for its final validation.
