For the data collection, three different questionnaires were used according to the focus of assessment of each group of participants. The data were analyzed through descriptive statistics, Content Validity Index assessment. It was considered a valid item the one that presented a value equal or higher than 0.78, and agreement level, presenting validation the item that obtained a minimum agreement of 75% in the positive responses. The judges’ observations were analyzed and, when necessary, the booklet was modified.

The main suggestions made by them were about the substitution or exchange of terms and suitability of texts. The target audience was adolescents aged 14 to 18 years. The agreement level in the positive responses given by adolescents was 82% and the main suggestions were associated with the booklet’s colors and illustrations.
