It is possible to distinguish between broad-domain theories that offer
an explanation for all phenomena of interest to a discipline and narr
ow-domain theories that attempt to explain a subset of those phenomena
. In criminology, this distinction has prompted theorists and research
ers to confront the question of whether the same etiological process c
an explain variation in all types of criminal offending behavior or wh
ether it will be necessary to adopt different theories to explain vari
ation in different kinds of criminal behavior. One broad-domain theory
, advanced by Gottfredson and Hirschi (1990), contends that a variable
called ''self-control'' can account for variation in all kinds of cri
minal conduct as well as variation in many acts that are ''analogous''
to crime in some ways bur are not actually criminal. Analogous behavi
ors include, among other things, smoking, drinking, involvement in acc
idents, gambling, and loitering. Using data from the Cambridge Study i
n Delinquent Development (N = 369 males), we attempt to define operati
onally the concept of self-control with a set of variables measured at
ages 8-9. We then examine the empirical association between this self
-control measure and self-reported involvement in a variety of crimina
l and analogous acts during adolescence. In support of Gottfredson and
Hirschi's position, our results indicate that self-control is associa
ted with both outcomes and that the strength of the association is app
roximately equal. Contrary to the expectations of their theory, howeve
r, was our finding that the covariance between criminal and analogous
behaviors could Mot be explained entirely by variations in self-contro
l. This finding suggests that factors other than time-stable differenc
es in criminal propensity do matter for criminal and legal, but, risky
behaviors.
