Background Stroke is one of the top causes of disability in Malaysia, yet caregivers have limited access to structured, culturally tailored education to support poststroke care. Objectives To develop and validate the CaknaStrok Education Package (CEP), a blended learning intervention comprising a printed guidebook and a trilingual mobile health application for informal stroke caregivers in Malaysia. Design Methodological study involving the development and validation of a caregiver education programme guided by the Analyse, Design, Develop, Implement, Evaluate (ADDIE) instructional design framework. Setting Development and validation were conducted in Malaysia between January 2022 and December 2023. Both experts and caregivers were recruited from two tertiary hospitals on the East Coast of Malaysia, with caregivers identified from inpatient wards and outpatient clinics at these hospitals. Participants Content validation involved 10 multidisciplinary experts. Face validation involved 14 informal stroke caregivers who met eligibility criteria, and all completed the study. Methods CEP was developed based on prior needs assessment and expert input. Content validation was undertaken using the Content Validity Index (CVI) and face validation using the Face Validity Index (FVI), both assessed on a four-point Likert scale. Qualitative feedback was also obtained from the participants. Results CEP consists of six modules delivered via a printed guidebook and a trilingual app with videos, assessment tools and local resources. Experts rated the content highly valid (Scale-level (S)-CVI/the average method (Ave): 0.97–0.99 across domains). Caregivers reported strong acceptability (S-FVI/Ave: 0.95–0.99). Qualitative feedback from experts and caregivers informed refinements to content clarity, usability and presentation, including improved navigation, consistent language use and enhanced visual design. Suggestions requiring substantial structural changes were documented for future iterations. Conclusions The CEP shows strong content and face validity as a blended caregiver education tool. By combining printed and digital formats, CEP addresses cultural and access challenges and provides a scalable model for stroke caregiver education in Malaysia. Further pilot or feasibility studies are warranted to evaluate usability, engagement and implementation in real-world settings prior to effectiveness evaluation.
