Sophie van Senden Theis (left) bringing Martha to Jessie Taft (right). Also pictured are Bobby Ueland (the adopted son of Elsa Ueland, another leading social worker) and Taft’s adopted son, Everett. Sophie was the first genuine adoption professional and researcher in the history of the United States. She was best known for her pioneering outcome study, How Foster Children Turn Out, published in 1924, in which Theis documented what had become of 910 children placed in homes by the New York State Charities Aid Association between 1898 and 1922. It was the first large-scale inquiry of its kind, became the prototype for many later outcome studies, and is still cited as a landmark in the history of adoption research.

Agreement among at least two evaluators is an issue of prime importance to statisticians, clinicians, epidemiologists, psychologists, and many other scientists. Measuring interobserver agreement is a method used to evaluate inconsistencies in findings from different evaluators who collect the same or similar information. Highlighting applications over theory, Measure of Interobserver Agreement provides a comprehensive survey of this method and includes standards and directions on how to run sound reliability and agreement studies in clinical settings and other types of investigations.
