Increasing knowledge about a screening test: preliminary evaluation of a structured, chart-based, screener presentation.

The provision and understanding of good quality information is one of the key characteristics of an informed choice. However, written materials alone often fail to achieve good understanding of screening tests. The present study describes the preliminary evaluation of a structured, chart-directed presentation, aimed at increasing knowledge of a screening test. Forty mothers of babies undergoing a newborn hearing test received either a standard, or a standard plus structured, presentation of the screening test. Standard presentation was a leaflet and short verbal explanation of the test. Structured presentation comprised an illustrated chart explaining the process and possible outcomes of screening, followed by screeners checking mothers understanding of key points and, if necessary, giving further explanation. After screening, maternal knowledge of the test was assessed using seven multiple choice items. Overall knowledge was high. For women with lower levels of education, the structured presentation resulted in significantly higher levels of knowledge than the standard presentation only.
