This study intends to characterize psychic atmosphere as a psychic development factor in pregnant teenagers. The case research in a qualitative approach was used within the framework of the clinical psychoanalytic method. 6 pregnant teenagers with ages between 14 and 17 years, from a low socio-economic level were chosen, whose pregnancies were not a result of sexual abuse and who belonged to the “Pregnant and breastfeeding mothers” of the Tunjuelito Secretary for Social Integration’s Local subdirection in Bogota. Three in-depth interviews were carried out with each individual. The psychic atmosphere of the pregnant teenagers has contributed to stopping psychic development altogether in 5 cases, and to its deterioration in the other case.
