Development of an appearance validity instrument for educational technology in health

ABSTRACT Objectives: to develop and evaluate the convergence of the instrument for the appearance validity of educational technologies in health. Methods: methodological study conducted in two steps. In step 1, the instrument items were developed, with subsequent content validity by nine specialists in the development of educational technologies in health. In step 2, the convergent validity between another instrument and the appearance instrument was performed. Correlation results above r> 0.3 and p <0.05 were considered as plausible convergent validity. Results: the ten items of the initial version of the appearance instrument were submitted to content validity that resulted in a final version with 12 items (Content Validity Index = 0.93). The correlation indexes were strong with the objective and appearance domains; moderate with motivation, organization and total; and weak with writing style. Conclusions: the appearance instrument demonstrated content validity and convergent validity, in addition to a strong correlation with the other instrument.

摘要 研究目的：开发卫生健康领域教育技术表面效度（appearance validity）测评工具，并验证其会聚效度。研究方法：本研究为分两阶段实施的方法学研究。第一阶段：完成工具条目开发，随后邀请9名卫生教育技术开发领域的专家开展内容效度检验。第二阶段：开展该表面效度工具与另一款测评工具的会聚效度验证，以相关系数r>0.3且p<0.05作为判定合格会聚效度的标准。研究结果：初始版本包含10个条目的表面效度工具经内容效度检验后，最终版本调整为12个条目，内容效度指数（Content Validity Index）为0.93。相关分析结果显示，该工具与目标维度、表面维度呈强相关，与动机、组织维度及总得分呈中等相关，与写作风格维度呈弱相关。研究结论：本研究所开发的表面效度工具兼具内容效度与会聚效度，且与另一款测评工具存在强相关关系。
