Contradictory results in the extant literature suggests that additional risk factors should be considered when exploring the impacts of maternal smartphone use on mother-infant relationships. This study used cluster analysis to explore whether certain risk factors were implicated in mother-infant dyads with high smartphone use and low mother-infant responsiveness. A cross-sectional survey of 450 participants in the UK measured infant social-emotional development, maternal depressive, anxiety and stress symptoms, wellbeing, social support, smartphone use, and mother-infant responsiveness. Participants were predominantly White (95.3%) and living with a partner (95.2%), with infants who were born full-term (88.9%). Cluster analysis identified three clusters characterized as; cluster (1) "infant at risk" showing high infant development concerns, high maternal smartphone use, and low mother-infant responsiveness; cluster (2) "mother at risk" showing high maternal depressive, anxiety, and stress scores, low social support, high maternal smartphone use, and low mother-infant responsiveness, and cluster (3) "low risk" showing low maternal smartphone use and high mother-infant responsiveness. Significant differences were found between all risk factors, except for maternal smartphone use and mother-infant responsiveness between clusters 1 and 2 suggesting that both clusters require early intervention, although interventions should be tailored towards the different risk factors they are presenting with., (© 2024 The Authors.

Dyadic behavioral synchrony is a complex interactional process that takes place between the mother and her infant. In the first year of life, when the infant is prelinguistic, processes such as synchrony enable the dyad to communicate through shared behavior and affect. To date, no systematic review has been carried out to understand the risk and protective factors that influence behavioral synchrony in the mother-infant dyad. The aim of this review was to identify and evaluate the factors that influence behavioral synchrony in the mother-infant dyad, when the infant is between 3 and 9 months old. Key electronic databases were searched between 1970 and April 2021, and 28 eligible studies were identified for review. As the results were largely heterogeneous, four subgroups of factors were identified: (i) infant demographics, (ii) physiological factors, (iii) maternal mental health, and (iv) miscellaneous factors. Identified risk factors and covariates suggest that social determinants of health, underpinned by biological factors, play a large role in influencing behavioral synchrony within the dyad. Implications for the need to identify additional risk and protective factors, as well as design support for at-risk families are discussed., (© 2022 The Authors.
