The study found that low self-control was significantly and positively related to parole failure; however, it was not the only variable that apparently had an impact on reoffending. Consistent with previous research, young parolees were more likely to violate parole, as were property/nonviolent offenders. First-time California Youth Authority admittees were more likely to have parole success. Low self-control did not have a significant impact on the length of time from release to parole failure. Study data were obtained from a sample of 4,146 juvenile offenders paroled by the California Youth Authority. The initial data collection was done from 1964 to 1965. The dependent variable was a measure of whether or not the offender successfully completed parole. Low self-control was measured with the self-control subscale of Gough's California Psychological Inventory. Control variables were the offender's age at time of sentencing, race, school grade, number of convictions, a violent offense, a first-time offense, and the number of months incarcerated. 3 tables and 28 references
