Background

Adequate knowledge in decision making about health, or informed decision-making, requires a thorough consideration of medical harm versus benefit, personal beliefs and values, familial input, and societal norms and pressures. Unfortunately, many medical decisions are made based on the interpretation of information a health care professional provides. In prenatal genetic screening, expectant couples are, at times, not informed about all aspects of the screening process and are thus only provided with information they retrieve or the health care professional deems important. This research presentation will describe the development of a valid and reliable measure of informed decision making in prenatal genetic screening (IDM-PGS) for clinical application.

Methods

Item response theory guided the development of a multidimensional instrument for IDM-PGS using an in-depth review of the literature and expert insight and feedback. After developing the instrument, content validity analysis through work with an expert panel and cognitive interviews with a small subset of expectant women will result in the final reliable and valid instrument for administration.

Results

The content validity evaluation led to a reduction in instrument length from 85 items to 50 items to meet the content validity index requirements for development of an instrument. Cognitive interviews are ongoing for analysis and adaptation of the instrument prior to administration.

Conclusions

Assessing understanding of knowledge is a difficult in healthcare settings. Upon completion of development and psychometric testing, this multidimensional instrument for IDM-PGS can be applied in clinical settings to ensure expectant women are making informed decisions regarding genetic screening during their pregnancy.
