A recent version of strain theory is Robert Agnew's 1992 general strain theory. Agnew's theory draws heavily on previous versions of strain theory, particularly those of Robert Merton, Albert cohen, Richard Cloward and Lloyd Ohlin, David Greenberg, and Delbert Elliott and associates. Agnew, however, points to certain types of strain not considered in these previous versions and provides a fuller discussion of the conditions under which strain is most likely to lead to crime.
