Deimann and Kastner-Koller present a study on the accuracy of maternal estimations concerning children's development. They compare mothers with concerns about their children's development, seeking advice at an outpatient clinic, to mothers without the need for educational counseling and mothers who sought advice because of their children's potential high abilities. The results challenge the ability of mothers' to give adequate information in particular when the child's development is delayed.
Willinger et al. focus on the well documented finding that mothers generally tend to slightly overestimate their children's development and investigate the function of this overestimation. The data support the authors' hypothesis that overestimation reduces maternal stress. These findings may be due to maternal defense mechanisms, an attempt to decrease cognitive dissonance, or mothers' feeling as though they are an extended identity of their children. Willinger et al. advise against using mothers as the only source of information on their children's developmental status, particularly with regard to language competences.
Koch et al. investigate the accuracy of kindergarten teachers' estimations and compare them to those of mothers. An analysis of normally developed kindergarten children shows a slight overestimation with respect to overall development. A comparison of mothers' and teachers' estimates in a sub-sample of above average developed children showed no significant differences between the two groups of caregivers.
Glascoe and Marks deal with the question of how to interview parents having developmental or behavioral concerns about their children, in order to identify children at risk. As prior findings show the inaccuracy of parents' information, Glascoe and Marks focus on the assessment of parental concerns, which proves to be a reliable screening technique. They provide a survey on the accuracy and validity of parents' concerns about development as measured by Parents' Evaluation of Developmental Status (PEDS), a structured interview to elicit such concerns.
Together, the papers in this special topic provide important ideas in dealing with parents and other caregivers as a source of information. While the use of concerns seems to be a promising perspective for interviewing parents, the studies suggest focusing on risk populations when standardizing parents' questionnaires.
