Investigations of the mental health of only children were also ongoing in Europe. In addition to reviewing this early literature, Van Krevelen (1946) studied the records of adult and child patients admitted to major psychiatric clinics in Leiden, The Netherlands, between 1931 and 1941 and found that the prevalence of only children was similar to or lower than their incidence in the general population. Based on a survey he conducted in The Netherlands during 1942-1945, he concluded that only children benefited from attending kindergarten more than others because it gave them the opportunity to learn the lessons from classmates that children with siblings learn at home.
