  • Reliability
  • Validity
  • Responsiveness
  • Interpretability (e.g., MCID/MID)

Trial-based services

  • Recommend best approaches to implement outcome research studies
  • Develop implementation materials (e.g., Protocols, IRB Submission Materials, Recruitment Materials, Training Guides, CRFs/Patient Diaries)
  • Manage PRO and ePRO data collection.

Analysis and validation

  • Provide statistical consultation
  • Develop statistical analysis plans
  • Analyze and interpret PRO data


  • Executive summaries and detailed reports of study findings
