| Abstract: | Two independent studies compared the MMPI performance of 2 groups of matched institutionalized delinquent boys, those who caused trouble in dormitories (SSs) and those who did not (GGs). In the 1st study, Scale 4 was the only statistically significant scale. Cross-validation found no scales statistically significant. Nineteen items which discriminated between SSs and GGs in the 1st study did not hold up in the cross-validation study. It is concluded that the MMPI has questionable value in discriminating between different levels and types of delinquents. |
