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.

The present study proposed to investigate the effects of level of acculturation and of language of the therapy interview on self-disclosure by Mexican-American women. It was predicted that self-disclosure would be affected by both level of acculturation and by the language of the initial therapy interview. The principal implication of this finding is that for the first-generation Mexican-American woman, that is, a woman who has not acculturated to the mainstream society, the language in which therapy is conducted constitutes a significant factor in predicting whether she is likely to self disclose and thereby benefit from the therapy. The findings of this study suggest that less acculturated Mexican-American women would be more likely to utilize mental health services if they are available in Spanish.

The present study directly contrasted the efficacy of biofeedback-assisted cue-controlled relaxation, biofeedback-assisted metronome -conditioned relaxation, and both procedures combined via one physiological and one subjective measure of relaxation under no-stress and stress conditions.

This study was designed to compare the clinical effectiveness of EMG biofeedback and progressive relaxation training in the treatment of muscle tension headache. These procedures also were compared with a treatment-element control group. Results from this study indicated that EMG biofeedback, progressive relaxation, and the control procedures all led to significant improvements across sessions on EMG and most self-report measures. There was little evidence that either treatment technique was superior to the other or to the control procedures. Although in most cases there were rather large numerical differences between groups, these differences generally were not statistically significant. Analysis of correlations between EMG and self-report data revealed a pattern of variable but generally nonsignificant relationships. However, for the biofeedback and progressive relaxation groups, there were a number of highly significant correlations. The pattern of correlations suggested that the relationship between EMG tension and subjective headache pain may be better predicted by something other than a strict linear model.

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.

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.
