Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in…

Social dimensions of the caregiving environment, like secure relationships to caregivers and high interactional classroom quality, are seen to directly or indirectly stimulate children's learning and development. However, little is known about the underlying processes, specifically with regard to the role of peers. To fill this gap we videotaped…

The present study examines the quality and domains of teacher-toddler interactions and associations with structural characteristics using data from 95 German early childcare settings. The results of the confirmatory factor analysis supported a two-factor structure of interaction quality assessed by the CLASS Toddler: emotional and behavioural…

Although observational instruments are considered to be the gold standard for measuring toddler childcare quality, large-scale studies often have to rely on interviews or questionnaires. However, it remains unclear whether such reports can serve as reliable indicators for childcare quality. The present study used the ITERS and FCCERS to examine…

Over the last few decades, research has consistently shown that process quality in child care centers and family child care varies substantially, but is mostly at a mediocre level. Based on the NUBBEK sample (National Study on Education, Learning and Upbringing in Early Childhood), an expanded model of process quality tests the influence of…
