Self-control as a personality measure
Section snippets
Method
A total of 36 male and 84 female undergraduates (mean age 26.7 years, S.D.=9.5 years) participated as part of a course requirement. The School's ethics committee approved the project prior to its commencement.
Participants completed individually and anonymously the Self-Control scale of Gibbs et al. (1998), the Conscientiousness scale of the NEO (Costa & McCrae, 1989), the BIS and BAS scales of Carver and White (1994), and then completed the custom-made scale of imprudent behaviour and responded
Results
In assessing statistical significance, the P<.05 level was used throughout.
Table 1 presents the means, S.D., intercorrelations, and Cronbach alphas for each of the measures. Inspection of the table indicates that: (1) with the exception of Imprudent Behaviour, all measures showed reasonable to good internal consistency; (2) Conscientiousness and Self-Control correlated significantly; and (3) the BAS measure correlated significantly with Self-Control but the BIS measure did not.

Discussion
The present study sought to determine (1) the extent of overlap between a measure of self-control based on the Gottfredson and Hirschi (1990) general theory of crime and standard measures of personality conceptually similar to it, and (2) whether the Self-Control measure is a better predictor of criterion measures relevant to the Gottfredson and Hirschi theory than the personality measures. As far as the question of overlap is concerned, the Self-Control measure was found to correlate
