The adoption of Blockchain-Based Certificate Verification (BBCV) in higher education offers a promising solution to issues of certificate fraud, inefficiency, and lack of transparency. To support the effective implementation of this innovation, a valid and reliable instrument is essential to assess stakeholders' intention to adopt BBCV. This study reports on the content validity assessment of a newly developed instrument designed for this purpose. The Content Validity Index (CVI) method, based on Lynn's approach, was employed to evaluate item relevance through the ratings of six experts in educational technology. The analysis involved calculating both Item-Level CVI (I-CVI) and Scale-Level CVI Average (S-CVI/Ave). Following expert evaluation, several items were deleted or revised, resulting in a refined instrument consisting of validated items across eight key domains: intention to adopt, innovativeness, optimism, discomfort, insecurity, perceived complexity, perceived compatibility, and resistance to change. All constructs achieved satisfactory S-CVI/Ave values (ranging from 0.80 to 0.92), supporting the instrument's content robustness and readiness for further psychometric validation.
