Abstract

Objective: To use a questionnaire to determine the levels of maternal decision-related distress, clarity of the pros and cons, and certainty when considering prenatal genetic diagnostic testing; and to assess the relationship between these constructs and patient characteristics. Method: Cross-sectional study. Voluntary, anonymous questionnaires distributed 2017–2019 to women referred for invasive prenatal genetic testing. Excluded: English or Spanish illiterate. Maternal characteristics were collected. Questions evaluated distress, decisional certainty, and decisional clarity on a 5-point Likert scale (range: 0 = low/uncertain/unclear to 4 = high/certain/clear). Analysis: non-parametric Kruskal–Wallis, correlation statistics, and ANOVA. Results: Forty-four female patients completed it. Most were married, white, Catholic, and multiparous. 58% had already made a testing decision. Patients expressed low distress levels (mean 1.18 ± 0.80) and expressed high decisional certainty (mean 3.28 ± 0.76) and clarity (mean 3.30 ± 0.99). Decisional certainty and clarity were positively correlated (r = 0.47, p <.01), whereas distress was negatively correlated with decisional certainty (r = −0.8136, p <.0005) and decisional clarity (r = −0.49, p =.007). No significant differences by religion or parity. Greater distress (p <.05) and less decisional clarity (p =.07) occurred between those still debating testing vs those who had decided. Conclusions: Higher maternal distress scores were associated with lower decisional certainty and decisional clarity in women considering prenatal genetic testing.
