To identify interventions to reduce parental stress and increase readiness of parents to care for their preterm baby. This scoping review was conducted according to the Joanna Briggs Institute Guidelines, using the following databases: Science Direct, Scopus, MEDLINE, and ProQuest. Thirteen articles were found and selected for review. The main psychological problem of parents of preterm babies includes stress, anxiety, and depression.
