The study findings show that prenatal injury along with poor rearing environments are indicators of low self-control which can be a factor of delinquent behavior and the authors suggest that future research is needed to examine the possible situational nature of low self-control during adolescence. According to the GTC, ineffective parenting results in low self-control. Moffitt’s Interactional Theory of Offending suggests that low self-control is related to delinquent and criminal behavior in the form of poor behavioral regulation and argues that prenatal injury is the underlying cause of low self-control. In 1979, the National Longitudinal Survey of Youth gathered information on the life experiences of a group of men and women between the ages of 14 and 21. In 1986, the survey was expanded to gather information on the offspring of the female respondents. The data was gathered biannually beginning in 1986 with the latest dataset available for 1998. The study sample was restricted to children between the ages of 6 and 10 in 1988 and 1990, which allowed for consistency with the GTC. Dependent variables along with independent and control variables are discussed. Tables, notes, references, and appendixes
