Readiness Estimate & Deployability Index


The Readiness Estimate & Deployability Index contains 6 subscales and is a self-report instrument, estimating the extent to which a registered nurse perceives readiness to deliver nursing care in austere environments such as disasters and conflicts. Originally developed through qualitative research in 1996 for use in the U.S. Armed Forces, the READI now belongs to the general public and is available for use in both military and civilian settings. The READI has also been adapted for use in Canada, Republic of Korea, and Japan. R.B. Flannery’s Model of Stress Resistance (2003) - mastery, attachment, and meaning - forms the theoretical basis. The six scales in the READI estimate:

  • Clinical competency
  • Operational competency
  • Survival skills
  • Group Identification and Integration
  • Personal/Physical/Psychological readiness
  • Leadership and Administration

The bibliography guides an understanding of the psychometric testing, lessons learned from, and future directions of the READI.



Funded by the congressionally sponsored Tri-Service Nursing Research Program (TSNRP), the READI was first conceived in the active component of the U.S. Army in 1996 through electronic brainstorming. Content analysis of focus group data gleaned from statements made by service members who had broad deployment experience yielded the six themes around which scale items were constructed. Content validity estimation and reliability testing followed in 2001, again funded by the TSNRP. In succession, the U.S. Army Reserve, the U.S. Air Force (active and reserve) and the U.S. Navy adapted the READI, using service-specific language. A civilian READI and versions in Korean and Japanese were developed as the instrument’s usefulness spread. Web resource development was made possible by the UT Health San Antonio School of Nursing.


Permission is granted to the general public for use of the Readiness Estimate & Deployability Index and its various adaptations.


As health care, nursing research, and nursing practice continue to advance, those who choose to use or modify a version of the READI will need to follow the guidance of current approved practice standards.
