3 Visual Impairment Scale of Service Intensity of Texas (VISSIT) Type of service: direct intervention and collaborative consultation Focus is on student need in the ECC areas What is the VISSIT ?

4 Creation of the VISSIT Field trials June 2013 retreat of the Service Intensity Subcommittee of the Texas Action Committee for the Education of Students with Visual Impairments History of the VISSIT

5 Research study proposal through Texas Tech University’s and Stephen F. Austin State University’s Institutional Review Boards Study approval and participant selection Study implementation- September March 2014 History of the VISSIT (continued)

11 Frequently Asked Questions PURPOSE Q: Can the VISSIT be used for all students on my caseload, including those with multiple impairments and/or those with deafblindness? How about infants? A: The VISSIT is designed to determine the appropriate type and amount of services needed for ALL students with visual impairments on the TVI caseload. Q: Is the VISSIT to be used as a caseload analysis? A: The VISSIT is not a caseload analysis tool but can be used as part of a process to determine appropriate caseload size. The VISSIT does not take into account issues related to workload (e.g., planning, travel, and material preparation). HOW TO USE THE VISSIT Q: Can professionals who are not teachers of students with visual impairments fill out the VISSIT? A: The VISSIT must be completed by a TVI who has the vision-specific knowledge to quantify the levels of service intensity. Q: How often should the VISSIT be completed? When might I complete the VISSIT? A: The VISSIT should be completed prior to any determination of service type and amount. It should be completed prior to any IEP or IFSP meeting so that the TVI can have data to determine and support recommended type and amount of services for students.

12 Information About the Study -38 responded and consented to participate -25 actual participants -81 actual VISSITs completed and returned -Electronic survey -Results of the study indicated that the tool is moderately valid and reliable

13 Was the VISSIT, in its entirety, easy to use? # QuestionVery difficult to use Mostly difficult to use Easy to useMostly easy to use Completely easy to use Total Responses Mean 1Easy to use? Was the VISSIT, in its entirety, easy to use? (n=25) Was the VISSIT, in its entirety, easy to use? (n=25)

14 Time Needed to Complete VISSIT The average time it took to complete the VISSIT per student was 31 minutes per student. Average time to complete was faster (15-20 minutes) after completion of several scales and with more familiarity. Time Needed to Complete the VISSIT

Did you base your VISSIT scoring of student need on the student's evaluation results? (n=24)

20 Revised VISSIT Based on feedback from the study participants, the instructions were simplified and reformatted to make it more user-friendly A test-retest phase of the study was conducted in March with the revised VISSIT asking the same participants to complete one additional administration of the tool on one student and take a short survey to assess the revisions of the scale.

23 Would you prefer to use a paper format or an electronic format of the VISSIT? (n=16)

24 Next Steps The electronic version has been completed. A website for accessing the electronic version is in development. Continuing data analysis to gather more information about various aspects of the validity and reliability of the tool. Next Steps

25 Filling Out the VISSIT – Sample Student Sample VISSIT – STUDENT A “Lily” Lily is a 5-year-old girl who has a history of “extensive multifocal cystic encephalomalacia involving bilateral cerebral hemispheres”. Dr. XXX reports, “likely cortical vision impairment”, legally blind and, "… appears to have no vision". Lily also has a history of HSV meningitis as an infant, cerebral palsy, seizure disorder, encephalopathy, and developmental delay. She is able to alert to sounds and to her name being called; turn or tilt her head towards music, bells, and instruments; sit in an adapted chair; smile when she is happy; and demonstrate discomfort (as when she is wet). She demonstrates the 3 distinct criteria for Cortical Visual Impairment: 1) eye exam does not explain the child’s functional use of vision, 2) history of a neurologic incident or some neurologic sequelae, and 3) demonstrates the unique visual and behavioral characteristics associated with CVI. With regard to her vision, Lily is able to visually attend to and track an 8-inch lighted red ball when it is presented in either her far left or far right visual field or no more than 12 inches away from her face. She also visually attends to other targets that are either lighted or have reflective qualities. No distance viewing is observed, other than staring at ceiling lights and sunlight for brief moments. Results from her learning media assessment indicate that Lily relies heavily on her auditory mode for learning, but will explore real objects that are of a single, bright color, reflective, and/or can light up. Lily is transitioning from a school-based self-contained classroom into a homebound setting with services being provided in her home.
