Study information
Scientific title
Impact of a psychological intervention in patients under assisted reproductive treatment (in vitro fertilisation [IVF]/intra-cytoplasmic sperm injection [ICSI]): a prospective (longitudinal) blinded randomised experimental intervention study
Acronym
Study hypothesis
1. A significant difference in psychological outcome is expected between groups. Specifically, it is assumed that the group with the psychological intervention will have better outcomes in terms of psychological functioning (quality of life and depression, suffering from infertility).
2. A difference in biomedical outcome is expected between groups. As above, it is assumed that the group in the psychological intervention condition will profit in terms of a higher chance of pregnancy.

The intervention consists of 10 weekly sessions organised according to 10 thematic blocks: a structured group/couple setting and a combination of educational and supportive therapeutic elements.
Waiting control group:
The control group is randomised to the waiting list control patients for 6 months. After this time they could participate in the intervention if they want.
