RT Article T1 Self-control and criminal opportunity JF Criminal justice and behavior VO 25 IS 1 SP 81 OP 98 A1 Longshore, Douglas A2 Turner, Susan 1954- LA English YR 1998 UL https://krimdok.uni-tuebingen.de/Record/1640112588 AB In this study, the authors tested two hypotheses drawn from the general theory of crime. The first hypothesis is that low self-control is a major individual-level cause of crime. The second, that the effect of self-control is contingent on criminal opportunity. The measure of self-control used was a 23-item self-report index. To measure criminal opportunity, two proxy variables were used: gender and crime-involved friends. Crime measures included number of criminal acts of force and number of criminal acts of fraud reported in a 6-month recall period by a sample of 522 criminal offenders. Self-control was lower among offenders reporting more crimes of force and fraud, but the variance explained by self-control was low in each case. The relationship between self-control and fraud crimes was contingent on criminal opportunity, but the relationship between self-control and force crimes was not. Implications of these findings for the general theory of crime are reviewed K1 Kontrolltheorie K1 Kriminalität K1 Selbstkontrolle K1 Allgemeine Kriminalitätstheorie
