There are other test which measure psychopathic tendencies, although they don't necessarily label "psychopathy" as that which they measure, for example some are "amorality" questionnaires (where amorality is roughly defined as a profound lack of regard for other people's feelings and well being etc.). Some are quite successful in discriminating various types of prison populations (that is, it doesn't just say "this person is severely lacking empathy", but it shows there are various types of psychopathic/anti-social trait clusters, and this reflects on real life behavioral history of individuals). I'm speaking from a strictly academic research background with this and a lot of time has passed since I looked into it so I'm not sure if the tests I'm talking about got any clinical use among non-prison population. However, a lot of this can be gleaned from good general purpose personality questionnaires.
