Use of the Newborn Behavioral Observations System as an early intervention for infants and their parents: A scoping review.

The Newborn Behavioral Observations (NBO) system is an infant-focused, family-centered, relationship-based tool designed to help parents become aware of their baby's abilities and to promote a positive parent-child relationship from the very beginning of birth. The aim of this scoping review was to provide an overview of the key characteristics of the research and evidence accumulated over the past 17 years on the early NBO intervention for infants and their parents to identify the existing research gaps and to inform the future direction of research on the NBO System. A scoping review guided by Arksey and O'Malley's methodological framework and the PRISMA-ScR Checklist was conducted. This review used six databases (PubMed, CINAHL, MEDLINE, Google Scholar, Ichushi-Web, and CiNii) and was limited to English and Japanese language articles from January 2006, when the NBO was developed, to September 2022. Reference lists were also hand-searched to further identify relevant articles from the NBO site. A total of 29 articles were selected. Through the analysis of included articles, four overarching themes were identified: (1) usage pattern of the NBO; (2) participants, setting, duration, and frequency of the NBO intervention; (3) outcome measures and effects of the NBO intervention; and (4) findings from a qualitative perspective. The review suggested that early NBO intervention had a positive impact on maternal mental health and sensitivity to the infant, confidence and knowledge of practitioners, and infant development. This scoping review shows that the early NBO intervention has been implemented in a variety of cultures and settings and by professionals of various disciplines. However, research to evaluate the long-term effects of this intervention on a wider range of subjects is needed. • The NBO is used in a variety of cultures and settings and by professionals of various disciplines. • Early NBO intervention had a positive impact on maternal mental health and infant development. • A lack of longitudinal studies and of studies that targeted fathers was also identified. • The NBO was able to promote interdisciplinary collaboration and family-centered care.
