Concept: In this review will be considered studies, which include the concepts of NBO or CLNBAS, as intervention. Context: This scoping review will consider studies wherever NBO/CLNBAS is provided. This will include, but is not exclusive to, hospitals, community and educational environment or social. Types of studies: this scoping review will consider quantitative, qualitative studies and systematic reviews. Search strategy: the search strategy aims to find both published and unpublished studies over the last io years from 2006 (date of its creation) to 2016. The search strategy aims to find both published and unpublished studies. A three-step search strategy will be used in this review. Studies published in English, Spanish and Portuguese will be considered for inclusion in this review. Data extraction: a data extraction instrument was developed, who include specific details about the populations, concept, context and study methods of significance to the scoping review question and specific objectives. Data synthesis: the findings are presented in a narrative form including tables and figures to aid in data presentation where appropriate. Results: welve studies published in English were included in this review. Research designs were mainly quantitative, and published in lastfve years, and made in United States of America. Most of the studies where carry out in home visits by different health care providers. Conclusion: The NBO is a flexible instrument that can be applied by many professionals, in different contexts, which allows a bigger interaction between parents and child, higher self-confidence, satisfaction, superior child competence and development knowledge by the caregivers, associated also to a reduction on the post-partum depression and anxiety, enhancing too their relationship and confidence in the health professional. On the other hand, by professionals perspective involved in the NBO intervention, they also felt more self-confident and with more knowledge on the intervention application. Implications for practice: The NBO can be an effective intervention in enhancing engagement, encouraging maternal role transition, and promoting attachment and bonding, to be integrated on the health policies'. However none of the studies evaluate the efficacy of nurses the intervention with NBO on primary health care center context. Reason that justifies the need to conduct a primary investigation in this area. [ABSTRACT FROM AUTHOR]
