Cancer literacy is currently one of the most important dimensions of cancer continuum. Objective assessment of cancer knowledge in populations remains a challenging field to public health entities. Different evaluation tools are currently available; still, some groups remain disregarded due to the absence of validated instruments. Cancer literacy in adolescents and young adults has been clearly overlooked being a subject that requires new tools to be properly studied. To address this topic, we developed a new instrument and field tested it in a classroom environment for internal reliability, construct, and face validity. "Students Knowledge and Perceptions about Cancer questionnaire" was designed in Portuguese language and adapted to the Portuguese context by a multidisciplinary team. The final version of the questionnaire includes 35 items organized in three sections, encompassing knowledge and perceptions about cancer and socio-biographic data. Cancer experts ensured content validity, while tailoring of contents was refined with high school teachers. Test and retest of the instrument showed a good reliability of the scale and construct validity. Also, the clarity of the questionnaire and suitability to proper evaluate cancer knowledge was consistent between test and retest. The Students' Knowledge and Perceptions About Cancer Questionnaire (SKPaC) showed to be a valid tool to assess adolescents' knowledge and perceptions about cancer that can be used in the educational context.
癌症素养目前是癌症连续统一体中最重要的维度之一。对人群中的癌症知识进行客观评估，对公共卫生实体来说仍是一个具有挑战性的领域。目前有不同的评估工具；然而，由于缺乏经过验证的工具，一些群体仍然被忽视。青少年和青年的癌症素养显然被忽视了，这是一个需要新工具才能进行恰当研究的课题。为了解决这个问题，我们开发了一种新工具，并在课堂环境中对其进行了实地测试，以检验其内部信度、结构效度和表面效度。“学生对癌症的知识与认知问卷”用葡萄牙语设计，并由一个多学科团队根据葡萄牙的情况进行了调整。问卷的最终版本包括35个项目，分为三个部分，涵盖了对癌症的知识与认知以及社会生物统计学数据。癌症专家确保了内容效度，同时与高中教师一起完善了内容的调整。该工具的重测显示出量表具有良好的信度和结构效度。此外，问卷的清晰度以及对癌症知识进行恰当评估的适用性在重测中保持一致。“学生对癌症的知识与认知问卷”（SKPaC）被证明是一种有效的工具，可用于评估青少年对癌症的知识与认知，可在教育环境中使用。
