The Consumer Health Information System Adoption Model.

Area of Science:

• Health Informatics
• Consumer Health Informatics
• Human-Computer Interaction

Background:

• Consumer health information systems (CHIS) empower individuals in managing their health.
• The increasing popularity of CHIS necessitates understanding adoption and success factors.
• Existing research suggests a link between usability, consumer eHealth literacy, and system demands.

Purpose of the Study:

• To introduce a new model, the Consumer Health Information System Adoption Model (CHISAM).
• To explore the moderating roles of consumer eHealth literacy and system demands on CHIS adoption.
• To identify strategies for aligning eHealth literacy skills with system requirements.

Main Methods:

• Development of the Consumer Health Information System Adoption Model (CHISAM).
• Conceptualizing eHealth literacy and system demands as moderators.
• Examining the impact of these moderators on the relationship between perceived usefulness/usability and adoption outcomes.

Main Results:

• Consumer eHealth literacy and system demands significantly moderate the relationship between system predictors and adoption outcomes.
• The model highlights how disparities in eHealth literacy and system complexity influence successful CHIS use.
• Alignment strategies are crucial for optimizing the effectiveness of CHIS.

Conclusions:

• The CHISAM provides a framework for understanding and improving CHIS adoption.
• Addressing both user skills and system design is vital for successful consumer health information system implementation.
• Future research should focus on empirically validating the CHISAM and testing alignment strategies.
