Scope of Study | |
| Summary: | The purpose of this data collection was to validate two classification systems, one for rapists and one for child molesters, used in a Massachusetts treatment center for sexually aggressive offenders. Rapists and child molesters were classified as two types of sex offenders and then clinically classified into subtypes based on criteria for the two taxonomies being tested. Variables include type of traffic offenses, criminal offenses, and sex offenses charged. Data on disposition of cases are also provided, along with parole and discharge information. Offenders' post-release offenses were categorized into traffic offenses, nontraffic offenses, and sex offenses. |

| Version History: | The last update of this study occurred on 2005-11-04. |
| 2005-11-04 - On 2005-03-14 new files were added to one or more datasets. These files included additional setup files as well as one or more of the following: SAS program, SAS transport, SPSS portable, and Stata system files. The metadata record was revised 2005-11-04 to reflect these additions. | |
| 2000-10-05 - SAS and SPSS data definition statements have been added to this collection. The data were reformatted to change the date variables from SPSS stored format to a month and year format that is not specific to any statistical package. A revised codebook, including a data completeness report, was created for the reformatted data file and original hardcopy documentation from the principal investigators was converted to PDF. | |
