Preschool predictors of loneliness in school‐age children

Chronic loneliness is a risk factor associated with adverse psychological, physical, and academic outcomes. Converging evidence suggests that young children experience and can reliably report on their own loneliness: thus, a clearer understanding of the risk factors for child loneliness is needed. The aims of this study were two‐fold: (a) to examine if temperament (i.e., negative affect, effortful control, inhibitory control), and attachment security assessed at the age of four predict loneliness at the age of six and (b) to determine if social competence at the age of five mediates the relation between temperament and attachment security at the age of four and loneliness at the age of six. Participants included a diverse sample of 796 4‐year‐old children, about half of whom were male. Results of hierarchical regression analyses indicated that lower levels of effortful control and inhibitory control at the age of four significantly predicted greater loneliness at the age of six. Also, while lower levels of negative affect (NA) and higher levels of effortful control and attachment security at the age of four significantly predicted higher levels of social competence at the age of five, social competence at the age of five did not predict loneliness at the age of six. There was no evidence that social competence at the age of five mediated the relation between the age of four temperament, attachment security, and the age of six loneliness. These findings reveal that early self‐regulation is associated with later child‐reported loneliness and that intervention for children who struggle with behavioral regulation may be effective in decreasing risk for later loneliness.
