«MIST (Melbourne Initial Screening Test) Evaluation Studies February 1998 Part 1: Reliability and validity testing of the MIST Part 2: A negative ...»
In the MIST vision screening program it could be recommended that all children who fail the test should be returned for a repeat test before being referred. This may result in an increased positive predictive value, but must be balanced against the constraints of the maternal and child health nurses’ working environment and the chance that some children may be lost from the system if they do not return for the repeat test.
Currently there appears to be a very good follow-up rate after failure of the vision screening test, demonstrating that there appears to be good parental acceptance of the worth of the program, with parents realising the importance of obtaining a full eye examination.

ACKNOWLEDGEMENTSThese projects were funded by The Department of Human Services, Victoria, Australia. The authors would like to acknowledge and thank Caroline Hall, Dianne Hoffman and Helen McKinley for their role as research assistants for the projects. Thanks to the orthoptists, nurses and ophthalmologists who performed the screening tests and gold standard assessments; to the maternal and child health nurses and the clinicians who took the time to complete and return the referral forms. Thanks also to all the parents and children who gave of their time to be part of the project.
