In this study violent and nonviolent prisoners were differentiated on the basis of life history and psychometric variables. Life history data were collected from institutional files and from a biographical questionnaire. Psychometric procedures consisted of the Mini-Mult Prisoner Questionnaire and the Bender-Gestalt. In summary, the variables included in the discriminant function suggest that the violent subjects were more psychopathological than the nonviolent subjects. The violent subjects evidenced behavioral problems at a young age in appropriately expressing anger. They appeared to have limited behavioral repertoires in attaining their desires outside the immediate gratification through aggressive means. They were also more emotionally alienated and less socially skilled. The violent subjects received more negative feedback during childhood and were incarcerated at a younger age, They were more overtly hostile and also more lacking in cognitive ego mastery. In contrast, the nonviolent subjects apparently learned during childhood to repress their anger to a greater extent. They also seemed to modulate their anger by withdrawing from direct interpersonal conflict.

The purpose of this study is to replicate and extend earlier work involving cluster analysis of MMPI profiles among persons with chronic low back pain. There are two specific goals. The first goal is to demonstrate the existence in a new sample of four distinct and homogenous profile clusters that have been found in previous research. The second goal is to investigate the relationship of the four profiles to the subjects, self-reported pain history and response to treatment. This study concludes that four distinct MMPI profiles can be identified among chronic low back pain patients. Further, these profiles are the same for males and females, and are the same profiles found in previous research. These profiles are significantly related to subjects' history of behaviors in dealing with pain. However, no relationship to treatment response was found. It was inferred that the MMPI is of value in understanding the nature of patients' pain coping behaviors, but that further research is needed before any statements can be made regarding the utility of the MMPI in understanding their response to treatment.

Previous research suggested that sleep onset insomnia was significantly reduced with the use of relaxation techniques; however, the majority of these studies used college student populations with mild to moderate insomnia. The objective of the present study was to assess the effectiveness of using muscle relaxation training in a clinical population known to have sleeping difficulties—cancer patients. Results of this study suggest that muscle relaxation training is an effective technique to reduce sleep onset insomnia in cancer patients, and perhaps also in any clinical group. The technique seems especially promising since it was shown to be effective with severe insomniacs suffering severe medical problems. Results of the study were discussed in terms of possible explanations for the efficacy of the treatment, potential uses of the technique with other clinical populations, and ease of teaching nonpsychologist health professionals to treat with muscle relaxation training.
