Additionally, divergent perspectives on parent responsiveness may limit cross-disciplinary collaborations, which are important to best support families in developing responsive parenting skills. Thus, the purpose of this systematic review of articles published from 1952 to 2022 was to establish a multidimensional definition of parent responsiveness.

We completed a qualitative content analysis of the definitions of parent responsiveness extracted from each included article. The resulting definition contains 15 dimensions of parent responsiveness across four levels of behaviour that comprehensively describe the complexity of parent-infant interactions.

Using a new analytic approach to capture individual variability in participants' arrangement in this task, we show that the spatial arrangement method has appropriate construct validity (<i>β</i> = 0.40), internal consistency (<i>r</i><sup>2</sup> = 0.20), and test–retest reliability (<i>r</i><sup>2</sup> = 0.41; ICC = 0.56) when used to evaluate semantic structure in U.S. children (4–9 years of age; <i>N</i> = 200 across 4 datasets).
