Are Behavioral Measures of Self-Control and the Grasmick Self-Control Scale Measuring the Same Construct? A Meta-Analysis

The Grasmick attitudinal scale of self-control (Grasmick, Tittle, Bursik, & Arneklev, Journal of Research in Crime and Delinquency, 30, 5-29, 1993) is one of the more commonly used measures in research on Gottfredson and Hirschi's (1990) self-control concept. What has yet to be determined is whether the Grasmick scale correlates as well with crime and delinquency as behavioral measures of self-control and whether the Grasmick scale correlates better with these behavioral measures than it does with crime and delinquency. A meta-analysis was performed on 13 samples obtained from published research where the Grasmick scale, a behavioral or consequences measure of self-control, and an estimate of crime or delinquency were all administered to participants. All analyses were computed with Comprehensive Meta-Analysis, Version 2 (Borenstein, Hedges, Higgins, & Rothstein, 2005) software. The results of the meta-analysis revealed that the Grasmick scale and behavioral/consequences measures of self-control achieved comparable correlations with concurrent measures of crime and delinquency but correlated no higher with each other than they did with crime and delinquency. Four possible interpretations of these results are considered: (1) the self-control concept advanced by Gottfredson and Hirschi is a tautology; (2) the attitudinal and behavioral/consequences measures of self-control are measuring different constructs; (3) self-control is a multidimensional construct; (4) self-report measures of behavioral self-control are inadequate for assessing low self-control.
