Abstract:

This dissertation is an archival study of violent versus nonviolent offenders' responses on the Rorschach Inkblot Test, a projective measure of emotional and personality functioning. A review of literature regarding the prediction of violence determined there is a plethora of research on this topic. Many studies have demonstrated the usefulness of predicting violence for legal purposes as well as the safety of the general public. The literature review also indicated that only a small number of self-report measures are being used in order to predict future violence. As a result, it is necessary to continue researching additional assessment tools that may be used to help mental health professionals increase their accuracy regarding the prediction that certain individuals will commit future violent acts. The intention of the current study is to provide both quantitative and qualitative pilot data for future research regarding the usefulness of the Rorschach Inkblot Method as an instrument to assess dangerousness. Twenty-six juvenile offender files were reviewed to retrieve archived Rorschach data; thirteen were violent offenders and thirteen were nonviolent offenders. Five Rorschach variables known to measure aggression were used to assess potential aggressive behaviors. These variables included Aggressive Movement (AG), Morbid (MOR), Aggressive Content (AgC), Primary Process Aggression (A1), and Secondary Process Aggression (A2). This last variable, A2, was found to be bordering on significance after completing independent samples t-tests. The group of violent offenders reported a statistically higher number of Secondary Process Aggression responses than the nonviolent group, indicating this group offers more aggressive responses than are typically considered socially acceptable. The qualitative analysis also produced some interesting results which suggested the nature of the violent groups' aggressive responses were more active and detailed, and contained fewer prosocial human interest responses. This latter finding indicated their inability to use fantasy as a defensive outlet and instead deal with frustration by offending violently. Both groups omitted texture and reflection responses indicating neither group had a healthy capacity of self reflection, nor demonstrated a need for warm, human contact. It is hoped that the Rorschach Inkblot Method will one day be used in combination with other assessment tools to more accurately determine an individual's propensity for committing future violent acts.
