The earliest data of the study were taken in the delivery room 2 minutes after delivery in the form of Apgar scores. Baseline data on mothers' child rearing values were collected with the Ernhart and Loevinter Authoritarian Ideology Scale before mother and child left the hospital. Using the Elliott and Ageton self-report of delinquency 18 years later, the developmental span to early maturity was covered prospectively. The predictors from birth to age 6 provide an account of early antecedents to delinquency in regression models. Four predictor models were used to examine the data: the developmental model; the family model; the maternal model; and the somatic model. Only the maternal model failed to have any significant antecedents for delinquency. For the developmental model, the Ad Hoc Scale score that assessed development at 1 year was related to delinquency reported at 18 years old. For the family model, the absence of the father was related to delinquency; and for the somatic model, gender was related to delinquency. 4 tables, 2 figures, and 50 references
