Purpose and Analysis of the Questionnaire

The Measure of Informed Choice (MMIC-16) questionnaire was developed in 2001 by Marteau and her colleagues and consists of 16 questions. The purpose of the questionnaire is to examine and measure an individual’s informed choices regarding prenatal screening for Down syndrome. The questionnaire is given to pregnant women who intend to undergo prenatal screening for Down syndrome.

Scoring and Statistical Analysis of the Questionnaire

The questionnaire includes 16 questions, which are divided into two scales. The first scale consists of 10 questions and measures knowledge about prenatal screening for Down syndrome. The second scale consists of 6 questions and measures the attitude toward prenatal screening for Down syndrome.
The first scale is scored on a 0–10 scale by choosing one of six available answers. Each correct answer scores one point. If the total score is 5 or above, the individual is considered to have a high level of knowledge.
The second scale is scored using a 7-point Likert scale from 1 (not at all) to 7 (very much). The maximum score is 36, and a score of 18 or above indicates a positive attitude toward prenatal screening. A high total score indicates that the participant has made an informed choice.

Validity and Reliability

The Cronbach’s alpha index shows satisfactory reliability for both scales: 0.70 for the 10-question knowledge scale and 0.76 for the 6-question attitude scale.
