The problem of early motherhood is still a serious medical and social problem in many countries around the world. The aim of this study was to analyze the attitudes of teenage mothers towards pregnancy and childbirth. A retrospective cross-sectional study was conducted with the use of an original questionnaire containing a test to measure attitudes on a five-point Likert scale and a Life Orientation Test-Revised (LOT-R) to assess dispositional optimism. The study involved 308 teenage mothers between 13 and 19 years of age. Attitudes of teenage mothers towards pregnancy and childbirth were more often positive (90.6%) than negative (9.4%). Sociodemographic features determining the attitudes of teenage mothers towards both their pregnancy and childbirth included their age, marital status, current occupation, and main source of income. The type of attitude adopted by teenage mothers towards pregnancy and childbirth was significantly related to the level of their dispositional optimism.
