This study assesses the communicative effectiveness of Italian HPV vaccination campaign materials using a mixed-methods design that combines expert annotation and a public perception experiment. A corpus of 49 official documents was annotated by six experts (three Linguistics Ph.D. students and three Gynecology residents) across 56 variables capturing the appropriateness and efficiency of verbal and visual elements. The perception experiment, administered to a convenience sample of Italian general public, examined attitudes toward HPV vaccination and evaluations of communication effectiveness. Overall, both expert and public assessments converged in judging the HPV vaccination campaign materials as relatively weak, citing reduced informativeness in overly concise texts, inappropriate choice of colors, and recurring issues regarding gender representation, inclusivity, and diversity.

This paper presents an annotation scheme developed to analyze linguisticaccessibility and inclusivity in Italian cancer-related informational materials.The scheme combines metadata annotation, qualitative analysis of textual andvisual features, and automatically extracted measures of linguistic complexitycapturing structural, lexical, and probabilistic properties of the texts. Abrief case study demonstrates how the proposed framework can be applied tocompare documents and identify different sources of linguistic difficulty. Theapproach provides a replicable methodological basis for large-scale analyses ofhealth communication materials.
