We would like to have any COMS who work in an itinerant service delivery model in an educational system use the O&M VISSIT (Orientation & Mobility Visual Impairment Scale of Service Intensity of Texas) this semester to determine the type and amount of O&M service to recommend for his or her students and to participate in our continuing validation study of the tool. The O&M VISSIT is a newly developed tool to assist an O&M specialist in making recommendations for the type and amount of service that are more objective and quantifiable and that are based on student need. We need as many COMS as possible to use the scale and participate in the study to increase the validity and reliability of the O&M VISSIT.

Participation only requires that:

  1. the COMS use the O&M VISSIT to determine service time for at least one student this school year (or as many students as they want),
  2. the COMS submit a copy of any completed O&M VISSITs (with no identifying student information) to a designated email address, and
  3. the COMS is willing to complete a short electronic survey on the use of the O&M VISSIT  by April, 2018.

If you are a COMS and are willing to participate in this study so that we can get feedback from more O&M VISSIT users, you just need to email me (rona.pogrund@ttu.edu) indicating your willingness to participate, and that will serve as your consent, and you will receive an email indicating the email address to upload your completed O&M VISSITs, and upon receipt of your scale(s), you will get another email with a link to the electronic survey later in the school year after you have submitted your completed O&M VISSITs.

An electronic pdf (that automatically adds up scores) and a Word version of the O&M VISSIT (along with background and instructions for using the scale and FAQs) can be found at: http://www.tsbvi.edu/o-m-vissit.

See the attached Information Sheet for more details of the study.

The study is being conducted by Dr. Rona Pogrund from the Sensory Impairment Program in the College of Education at Texas Tech University along with Heather Munro, Ph.D. student at TTU, and Dr. Shannon Darst, adjunct professor at TTU.  If you have any questions about the study, you can contact Rona Pogrund at the email address above or at 512-206-9213

TTU also has a Board that protects the rights of people who participate in research.  You can ask questions of the Board at 806-742-2064 or to hrrp@ttu.edu.  You can also mail your questions to the Human Research Protection Program, Office of the Vice President for Research, Texas Tech University, Lubbock, Texas, 79409.

We hope that your participation can help us understand more about how to help you determine your students' needed O&M service time. We appreciate your willingness to participate in this study.
