pregnant women who had only prenatal genetic screening tests in intervention group, pregnant women, who were in 8-11th gestational weeks, before prenatal genetic counseling, answered the questions in "descriptive features data collection form", "decisional conflict scale", "the state-trait anxiety inventory scale", "information evaluation form about prenatal screening tests ","decision satisfaction scale", "attitudes towards the tests scale". later, individual interviews were made with pregnant women education was given with slide show about prenatal diagnosis and screening tests to pregnant women. in addition a training brochure which was prepared by the researcher was given to the pregnant women. it took about 20 minutes for the data collection forms to be answered and counseling was took about 25 minutes. after counseling, pregnant women were interviewed again at 14th week. the pregnant women were asked whether they had a screening test and the results were recorded. then pregnant women were answered "decisional conflict scale", "the state-trait anxiety inventory scale", "information evaluation form about prenatal screening tests ","decision satisfaction scale", "attitudes towards the tests scale" again. at the following antenatal visits (16-20th weeks), the pregnant women were asked whether they had triple, quadruple or nipt and the test results were recorded in the data collection form. at the end of the 20th week, the data collection process of pregnant women who did not have any problems related to fetus and who were recommended to continue routine follow-up was terminated. in control group pregnant women answered same data collection forms in same weeks, but counseling was not given to this group. for this group routine clinical procedure was performed. pregnant women who had also prenatal genetic diagnostic tests prenatal genetic diagnostic tests were recommended to pregnant women who had high risk results according to prenatal screening test. pregnant women with high risk and diagnostic test were referred to genetic consultation in both intervention and control groups. after genetic consultation, pregnant women were answered "decisional conflict scale", "the state-trait anxiety inventory scale", "information evaluation form about prenatal diagnostic tests", "decision satisfaction scale", "attitudes towards the tests scale". then specific counseling was given to invasive test recommended by the doctor. the pregnant woman was asked if she would like to have a diagnostic test and if she didn't want to, the reason was recorded in the data collection form. if the pregnant woman decided to have a diagnostic test, "the state-trait anxiety inventory scale" was applied again after the procedure. then pregnant women were interviewed again after about three weeks and their results were evaluated and they answered "decisional conflict scale", "information evaluation form about prenatal diagnostic tests", "decision satisfaction scale", "attitudes towards the tests scale". their decision about to continue or terminate pregnancy was recorded in the data collection form. in control group pregnant women answered same data collection forms in same weeks, but counseling was not given to this group. for this group routine clinical procedure was performed.
