Research Background and Problem

• Identified Challenges:
  • U.S. veterans often face difficulties reintegrating into society due to post-traumatic stress disorder (PTSD), with a higher prevalence compared to the general population.
  • PTSD symptoms typically manifest as trauma re-experiencing, negative changes in mood and cognition, avoidance behaviors, and hyperarousal. Without treatment, these symptoms significantly increase the risk of health issues, domestic violence, or suicide.
  • During PTSD treatment, patients frequently struggle to actively engage and often drop out, particularly among veterans of the Afghanistan and Iraq wars.
  • Existing PTSD treatment methods relying on patient self-reports have limitations, as clinicians often lack a deep understanding of military culture.
• Significance:
  • Social support plays a critical role in PTSD treatment and recovery, reducing treatment dropout rates.
  • Trusted others (e.g., family members or friends) can provide behavioral observation information that patients may be unaware of or unwilling to disclose, offering a valuable supplement to diagnosis and treatment.
• Research Motivation and Related Work:
  • The study aims to explore how to systematically integrate trusted others' feedback to optimize PTSD treatment.
  • Recent research in the field of Human-Computer Interaction (HCI) has focused on developing technologies to increase patient engagement in treatment but has not specifically addressed how to leverage trusted others' feedback to support PTSD treatment.

Solution

• Proposed Solution:
  • A "Social Sensing System" is proposed, which collects trusted others' behavioral observation feedback on PTSD patients via SMS and integrates it into the PTSD treatment process.
• Innovations:
  • Formally incorporating trusted others' perspectives into evidence-based PTSD treatment to enhance information access for both patients and clinicians.
  • Designing symptom cluster-based SMS tools (e.g., for avoidance behaviors, hyperarousal) to provide customized feedback mechanisms for trusted others.
  • Employing a mixed-methods approach to design and test a system prototype, considering the needs and perspectives of patients, trusted others, and clinicians.
• Implementation Steps and Techniques:
  1. Phase 1: Clinician Perspective
     • Collaborate with 10 clinicians experienced in PTSD treatment to select and adapt questions from the PTSD Checklist for DSM-5 (PCL-5) for trusted others to answer.
     • Collect clinicians' feedback on keyword usage and SMS feedback content design through surveys and semi-structured interviews.
  2. Phase 2: Veterans and Trusted Others' Perspectives
     • Conduct storyboard-based interaction prototype testing with 10 veterans, 8 trusted others, and 2 participants serving dual roles.
     • Evaluate participants' attitudes toward the system and their assessment of symptom observation functionality through interviews and surveys.
  3. Data Analysis and Preference Summary
     • Apply thematic analysis to participant feedback and summarize commonalities and differences across groups (veterans, trusted others, and clinicians).
     • Use Davis's "Mechanisms and Conditions Framework" to critically examine the system's impact on social structures and power dynamics.

Research Findings

• Outcomes and Advantages:
  • System Design: Identified scenarios where trusted others' input is most applicable in PTSD diagnosis and treatment, especially in strong trust relationships like those between veterans and close family members (e.g., spouses).
  • Symptom Observation: Confirmed that trusted others are most effective at reporting PTSD symptoms such as avoidance behaviors and hyperarousal, providing a valuable supplement to patient self-reports.
  • System Usability: 27 out of 30 study participants expressed willingness to use the proposed system, believing it could improve treatment engagement and communication.
  • Design Recommendations: Proposed several design improvements, such as using positive language in questions ("engagement" instead of "avoidance"), anonymizing feedback, and implementing patient-controlled data access.
• Experimental Results:
  • Different groups (veterans, trusted others, clinicians) have varying needs regarding the frequency and format of system information, necessitating customizable content and data presentation.
  • Veterans prefer anonymized feedback data but still want some control over data access.
• Limitations and Future Directions:
  • Sample Limitations: The study primarily involved veterans with existing supportive relationships, leaving the applicability to isolated individuals untested.
  • Practical Testing: The system needs further validation in real-world treatment settings to assess its clinical impact.
  • Extended Research: Explore integration with non-human mediators (e.g., sensor data) and the multi-layered user interaction design proposed in the study.
