Paper Information

• Subject Area: Human-Computer Interaction (HCI) and Psychosocial Intervention Design
• Keywords: Mental Health, Complex Interventions, Psychosocial Interventions, Theory, Behavioral Science, HCI, Design Framework

Research Background and Problem

• Problems and Challenges:

  • Psychosocial interventions for mental health issues (e.g., psychotherapy, counseling) are often complex and difficult to implement effectively where patients need them most.
  • Current HCI research faces challenges in interdisciplinary integration when applied to mental health interventions, such as balancing innovative design with adherence to established psychological theories of change.
  • In existing interdisciplinary approaches to designing mental health technologies, there is often a methodological misalignment between HCI methods, which emphasize user experience innovation, and psychological methods, which emphasize intervention efficacy.

• Significance:

  • Technology has the potential to scale mental health interventions, reduce costs, and provide more interactive solutions, while HCI design can drive meaningful innovation in intervention technologies through user-centered design.

• Research Motivation:

  • Previous work has demonstrated diverse contributions of HCI to the mental health domain, such as remote psychotherapy and emotion monitoring tools, but there is a lack of a unified framework to define the scope and theoretical foundation of these contributions.
  • The goal is to develop a modular framework to help HCI researchers balance innovation and theory in psychosocial intervention design, standardizing design and evaluation methods.

Solution

• Method and Framework:

  • A modular framework is proposed, defining four levels of HCI design contributions to psychosocial interventions: capabilities, components, intervention systems, and intervention implementations.
  • The framework uses the "theory of change" from the mental health field as a foundation, translating it into "design briefs" in the HCI domain, emphasizing the integration of psychological functional needs with user needs.

• Innovations:

  • Redefines psychosocial interventions as "designs for supporting experiences," allowing HCI contributions to impact multiple levels, from technological capabilities to system implementation, through a modular approach.
  • Bridges the gap between psychological "theories of change" and HCI "design briefs," enabling better vertical integration between the mental health and HCI fields.
  • The modular architecture enables HCI researchers to focus on contributions at a single level without being overly concerned about the comprehensive implementation of subsequent interventions.

• Implementation Steps and Key Techniques:

  1. Define design briefs at each level:
     • Capabilities: Fundamental building blocks of interaction design, such as features for emotion tracking.
     • Components: Combining one or more capabilities to provide well-defined psychological functional interventions, such as tools supporting behavior activation planning.
     • Intervention Systems: Integrating multiple intervention components to fulfill a complete theory of change, such as comprehensive online therapy programs.
     • Intervention Implementations: Adapting intervention systems to specific contexts (e.g., cultural or environmental) and addressing socio-technical barriers to implementation.
  2. Determine evaluation perspectives and methods for design briefs:
     • Employ appropriate evaluation methods at different levels, such as user experiments, randomized controlled trials (RCTs), or embedded implementation science approaches.
  3. Generate new design challenges and questions through literature reviews, co-creation with users, and other methods to guide future research.

Research Outcomes

• Main Findings:

  • A modular framework for cross-disciplinary HCI and mental health research was proposed and validated, promoting alignment between design and theories of change.
  • The framework delineates potential HCI contribution types across four functional levels, from technological innovation to deep implementation, clarifying research scope and enhancing practicality.

• Advantages:

  • Addresses the challenge of interdisciplinary integration in HCI research for mental health interventions, particularly the issue of methodological alignment.
  • Encourages theory-driven innovation in HCI research while accommodating rapid experimental validation.

• Experiments and Evaluation:

  • Demonstrated how design briefs support psychological functional goals through examples such as emotion monitoring tools and behavior activation goal-setting modules.
  • Highlighted evaluation priorities at different levels, such as interaction performance at the capability level and mental health outcomes at the system level.

• Limitations and Future Directions:

  • Limitations: Further exploration is needed to simplify interdisciplinary communication, especially regarding the integration of evaluation methodologies.
  • Future Directions: Extend the framework to a broader range of populations and application scenarios; further couple HCI design innovation with the practical needs of implementation science.

Conclusion

The proposed framework effectively provides structured and theoretical guidance for HCI contributions to mental health interventions, emphasizing the integration of psychological functional goals with design innovation. By defining clear levels and design briefs, it offers a systematic language and research pathway for interdisciplinary collaboration between mental health and HCI researchers.
