Maternal personality influences the relationship between maternal reports and laboratory measures of child temperament

Previous research has indicated that agreement between maternal reports of child temperament and laboratory measures is modest; however, it is unclear whether maternal characteristics influence convergence between methods. We examined whether mothers' personality influenced agreement between maternal reports and observational measures of child traits. A total of 64 mothers and children participated in this study. Maternal negative emotionality (NE) moderated the relationship between maternal reports and laboratory measures of child temperament: Greater convergence was found between maternal ratings of children's negative emotional traits and laboratory measures for mothers with higher NE than mothers with lower NE. Findings are consistent with the possibility that mothers' own traits influence the extent to which they successfully encode and/or report on analogous child behaviors.
