The purpose of this study was to explore the nature of the psychological impacts experienced by mothers related to the NBS process.  Methods: An online parenting community in Korea was selected, and questions regarding NBS were collected using web crawling for the period from October 2018 to August 2021. In total, 634 posts were analyzed. The collected unstructured text data were preprocessed, and keyword analysis, topic modeling, and visualization were performed. Results: Of 1,057 words extracted from posts, the top keyword based on \u2018term frequency-inverse document frequency\u2019 values was \u201chypothyroidism,\u201d followed by \u201cdischarge,\u201d \u201cclose examination,\u201d \u201cthyroid-stimulating hormone levels,\u201d and \u201cjaundice.\u201d The top keyword based on the simple frequency of appearance was \u201cXXX hospital,\u201d followed by \u201cclose examination,\u201d \u201cdischarge,\u201d \u201cbreastfeeding,\u201d \u201chypothyroidism,\u201d and \u201cprofessor.\u201d As a result of LDA topic modeling, posts related to inborn errors of metabolism (IEMs) were classified into four main themes: \u201cconfirmatory tests of IEMs,\u201d \u201cmother and newborn with thyroid function problems,\u201d \u201cretests of IEMs,\u201d and \u201cfeeding related to IEMs.\u201d Mothers experienced substantial frustration, stress, and anxiety when they received positive NBS results. Conclusion: The online parenting community played an important role in acquiring and sharing information, as well as psychological support related to NBS in newborn mothers. Nurses can use this study\u2019s findings to develop timely and evidence-based information for parents whose children receive positive NBS results to reduce the negative psychological impact.
