Tóm tắt	The PIIS is an observational coding system designed to assess the quality and reciprocity of parent-infant interaction during naturally occurring or semi-structured contexts. Developed by Summers et al. (2001) in the context of early intervention research, it captures dimensions of parental sensitivity, responsiveness, and infant engagement. The PIIS is primarily used in research examining attachment quality, intervention effectiveness, and developmental trajectories in infants at risk for developmental delay or social-emotional difficulties.	The NBO is a brief, observation-based system designed to illuminate newborn behavioral competencies and individual differences for parents and healthcare providers. Developed by J. Kevin Nugent and colleagues as a companion to the longer Neonatal Behavioral Assessment Scale (NBAS), the NBO uses 18 key behavioral observations to characterize newborn strengths and to guide parent education about infant cues, state regulation, and social capabilities. Unlike the NBAS, the NBO does not generate numerical scores but instead provides qualitative, parent-centered interpretation emphasizing infant strengths and readiness to interact.
