摘要

As the digital health technologies continue to play an increasingly significant role in healthcare, assessing individuals’ competencies in navigating these technologies becomes paramount. The study aimed to develop the Digi-Health Competency Scale (DHCS) and establish its content and response process validity among the Youths in India. An initial item pool for the DHCS was generated through a comprehensive literature review. Content validity was assessed by a multidisciplinary panel of eight experts using a two-round Delphi process. Item-level and scale-level content validity indices (I-CVI and S-CVI/Ave), content validity ratio (CVR), and modified Kappa statistics were calculated to evaluate expert agreement. Cognitive interviews using the think-aloud method were conducted with six youth participants to assess item clarity and interpretability. The final scale comprised 28 items. The I-CVI values ranged from 0.875 to 1.00, and the S-CVI/Ave was 0.91, indicating strong content validity. Kappa statistics demonstrated high levels of agreement among experts. Minor revisions were made to item wording based on expert feedback and cognitive interview findings to improve clarity and relevance. The DHCS demonstrates strong content validity and provides a preliminary, content-validated item pool for assessing digital health competencies among youth. Comprehensive psychometric evaluation, including construct validity and reliability testing, has been conducted as part of a subsequent phase of this research and is reported separately. Further research is needed to establish the scale’s full measurement properties.
