[ODP] Criminal and antisocial behavior and cognitive ability in a sample of dating si

#8
Low cognitive ability has repeatedly been linked with antisocial and criminal conduct.  The relationship appears to be robust and not conditioned by the measurement of cognitive ability or problem behavior.  In this sense, the findings presented here converge with other studies.

The measurement of cognitive ability remains unclear.  It would be helpful to know the actual 14-items used to create the scale, their content, and distribution.  As the core variable in the analysis more detail is necessary.

The criminal behavior measure is, of course, a bit limited but prior research shows that even content limited measures usually have good statistical and content validity.  Given the items included, which range form minor forms of deviance (cheating on tests), to more serious indicators of criminal behavior (arrest/prison), the expectation that a uniform factor would be extracted seems misplaced.  Yes, criminals are generalists and this is confirmed with the inter-item correlations, but you really do not have a sufficient number of items to produce a reliable, single factor.  

I would suggest creating a summated index and comparing the results against the results of found using only arrest.  The additional variance in the index would allow you to more closely examine how cognitive scores perform across the index.  Is a score of zero on the crime index associated with a cognitive score that is significantly higher than ascending index scores?

Prior research seemingly converges to show that average IQ differences between delinquents and non-delinquents is around .5sd.  For adult offenders, average differences around 1sd are common.  How much difference are we seeing with this sample of older, probably better educated and less criminal, men and women?

I’m not concerned with the performance of the age variable.  Age, as you point out, can be thought of as an exposure period, or depending on the items used to construct the cognitive ability scale, it could reflect domain specific knowledge that is age-graded.  Who knows.  

Lastly, the sample is clearly highly selected but I don’t see this as a problem.  Yes, the sample is composed of older people who use the internet and a case can be made that subjects may be a bit brighter than comparatively situated others......but the effect of this type of selection would be to minimize variance on crime and cognitive measures.  The results would thus be more conservative compared to samples that contain more variance in these measures.
