Although the Intellectual Development (ID) index was constructed using standard psychometric procedures, the derivation of the other two indexes, Socio Intellectual Status (SIS) and Differential Intellectual Development (DID), by criterion scaling should have applications in diverse areas of scale or index construction. The ID is basically comparable to an intelligence quotient index. The SIS is somewhat analagous to a Socio-Economic Status (SES) index, while the DID reflects intellectual achievement independent of the SIS family background contribution to the ID Index. The use of the three indexes in studying findings from the Cycle II children's survey (aged 6-11 years) of 1963-65 helps to clarify some persistent issues related to intellectual achievement. The first-order analyses revealed statistically significant relationships between the ID Index and (1) number of pregnancies previous to the birth of the examined child; (2) twin versus nontwin birth status; and (3) attendance vs. nonattendance at nursery school and/or kindergarten. However, these relationships were mostly attributed to family background factors reflected in the Socio-Intellectual index. Although the numerical index values derived in this report are specific and limited to the data of the Health Examination Survey Cycle II (children) and Cycle III (youths), the data base should have widespread applicability to behavioral scientists. Statistical data are appended, as well as brief notes on criterion scaling, multiple linear regression, and skewness and kurtosis tests. (Author/CP)
