Frosch CA, et al. - This investigation was conducted by the University of North Texas, USA, to study the longitudinal relationship between emotional connection at 6 months of age and behavioural problems at 3 years using the Welch Emotional Connection Screen (WECS), a brief screening tool for relational health. For this analysis, researchers enrolled 49 mothers and infants from a longitudinal investigation of family interaction and infant development carried out in 1994-1997. Face-to-face interaction and the toy-based play was videotaped and coded at the age of 6 months. According to findings, children from dyads who were rated emotionally connected at the age of 6 months had fewer behavioural problems externalizing and internalizing at the age of three. There were no connections between emotional connection during toy-based play at 6 months and later child behavioural problems. Overall, the investigators concluded that it was a promising and valid relational screening tool for infants at risk of adverse behavioural outcomes at the age of three when WECS was used at 6 months of age.
