[Psychological aspects of diagnostic methods in pregnancy]

Psychological effects and sequelae of prenatal diagnostics are presented using material of clinical trials and the results of client-centered counselling. All methods (ultrasound, alpha-fetoproteinscreening, amniocentesis and chorionic villous sampling) can only be understood with their effects upon mother - fetal bonding. A decision process, invasivity and discussion about a fetal malformation are the main characteristics of amniocentesis. High-risk populations like women with complicated pregnancies or advanced age profit most by prenatal diagnosis. The reactions and emotions of male partners are also discussed. The following guidelines for counselling are proposed: non-directive counselling dealing with facts and emotions, patient autonomy and preparation routines apt to reduce anxiety.
