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.

This study was designed to compare the effects of exposure to two different sets of soluble discrimination problems, an easy set composed of only two- and three-dimensional problems and a more difficult set composed of problems ranging from two to seven dimensions, both immediately after training and at a 10-day posttreatment follow-up. The subjects were 32 depressed male inmates of a federal correctional institution. It was hypothesized that as a result of meeting and mastering progressively more difficult problems, the group given progressively more difficult problems would show a greater reduction in depression and a greater enhancement of performance on a variety of cognitive measures, both immediately after treatment and at the 10-day posttreatment follow-up. The results failed to support these hypotheses. Depression scores decreased significantly from pretreatment to posttreatment, but did so equally for the two groups. One of the cognitive measures, the WAIS Digit-Symbol subtest, showed significant improvements from pretreatment to posttreatment, but did equally for the two groups. Significant relationships were found between the subjects' performances on the cognitive tasks, and measures of their tendencies to attribute successes and failures to stable or unstable factors. Unexpected significant positive relationships were found between depression and performance on the …

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.

The effectiveness of local norms with two short forms of the MMPI was investigated in this study. Comparisons were made between high-point code-type concordance rates and the overall concordance rates generated by local norms and the original norms of Faschingbauer's Abbreviated MMPI (FAM) and the MMPI-168. The use of local norms did not produce significantly higher high-point code-type concordance rates than the use of original norms. The use of local norms was indicated when one is interested in overall profile concordance. However, this finding was not replicated in the cross-validation samples. No conclusion was reached regarding the superiority of one short form over the other in terms of high-point codetype concordance. In terms of overall concordance, the FAM was found to generate higher concordance rates than the MMPI-168 when original norms were used. Overall concordance rates were not significantly different between the two short forms when local norms were used. Design changes and possible explanations for the findings were discussed. The former included increasing the sample size of the cross-validation samples to reduce sampling error. The latter consisted of the lack of congruence between the factor structures of the FAM and MMPI-168 and that of the MMPI, possible similarities between …

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 present study investigated female sexuality by examining a range of experiential, historical, attitudinal, and behavioral variables, and conceptualizing sexual orientation along several dimensions on a heterosexual/homosexual continuum. The focus was on determining what, if any, important etiological factors emerged, as well as differences in behavior, attitudes, and preferences among women with various sexual orientations. It was concluded that a nonconventionality factor could be interacting with certain experiential and situational variables to produce a bisexual or homosexual lifestyle. Consequently, the ideosyncratic variable nature of such a paradigm could partially explain inconsistencies in past research. Results of this study were comparable to previous ones indicating that the women were similar (across sexual orientations) in their emphasis on emotional aspects of a relationship, history of heterosexual dating and coitus, few (relative to males) sex partners, and a less (than males) actively assertive sexual pattern of behavior. Future research might include males in the investigation of the role of a nonconventionality factor in sexual orientation. Also, relationship between cognitive/perceptual styles and sexual orientation could be explored.

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.

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.

There is a scarcity of objective criteria upon which to select among the available therapies for those most likely to benefit specific patients. Comparative research has suggested that the outcomes of alternative and competitive therapies are equivalent. There are few facts available concerning which patients benefit most from even the more popular therapies. The purpose of this study was to find a type of patient for which differential improvement could be predicted. Neither therapy decreased checklist scores or increased speaking time significantly more than the other. Repressors and sensitizers responded equally to therapy. When dropout rates were analyzed there were also no significant differences between the therapies or between repressors and sensitizers. When posttherapy scores from both therapies were compared to pretherapy scores, no significant changes were found. The latter finding was important for understanding the absence of support for the hypotheses. Since the subjects did not improve as a result of either desensitization or rational-emotive therapy, there was no opportunity to observe the hypothesized differential changes. Given this hindsight, it was concluded that speech anxiety may not be a desirable disorder with which to study the prediction that repression-sensitization is related to the outcome of rational-emotive therapy and desensitization. …

A double-blind comparison was conducted using typical doses of soporific agents from three drug classes and a placebo. Drugs which were used in the study included secobarbital, flurazepam hydrochloride, and thioridazine. Subjects were 40 outpatient volunteers whose primary complaint was difficulty in falling to sleep. Subjects were randomly assigned to one of the three drug groups or the placebo group. One of the drugs or the placebo was administered to each subject for 3 nights. Half of the subjects in each of the four groups were told the drug had caused any observed changes in their sleep behavior and were in this way led to attribute any changed sleep behavior externally to the drug. The other half were told the drugs were not typically used to treat insomnia and changes in their sleep were due to changes made in their own behavior, thus attributing any changes in sleep behavior internally. The implication for clinicians was that a short course of drug therapy using a placebo or one of several soporific drugs might be used equally effectively to treat primary latency insomnia. Additionally, the results demonstrated that clinicians might expect the effectiveness of treatment to be maintained following treatment. Recommendations included …

Effects of selection risk on sex discrimination in hiring were investigated. Ninety-six male and female educational administration graduate students rated ficticious resumes on suitability for hiring for the female-oriented position of secondary school teacher. Sex and selection risk level were varied, with sex of rater as an assigned factor. Analysis of variance yielded significant main effects for sex (p < .01) and selection risk level (p < .05). All ratings were lower in high selection-risk situations, with males preferred over females across both levels of risk. Results suggested that ratings were based on a stereotype of female inferiority in work efficiency, overriding job sex-orientation as a decision factor.

According to Suls' (1972) incongruity model for the appreciation of jokes, humor with which recipients are familiar should not be perceived as funny because the ending is predictable. Suls (1975) later proposed that familiar humor is appreciated because of the sense of competence derived from adequately remembering the joke. This study examined Suls' theories by having subjects rate jokes on two occasions and supply their punch lines on the second occasion. Statistical significance was determined through the use of the t test for correlated means. Jokes for which punch lines were recalled were perceived as significantly less funny than on the first occasion. The results did not support predictions made from Suls' competence theory but did support those derived from Suls' incongruity model.

Although research has linked the central nervous system with changes in immunoresponsivity, research on the possible role of the central nervous system in altering reticuloendothelial activity is lacking. This study investigated the possible relationship between hypothalamic structures and changes in responsivity of the reticuloendothelial system. Eight male albino rats received bilateral electrode implants in the ventromedial area of the hypothalamus and, following brain stimulation, reticuloendothelial activity was assessed 3, 6, 12, 24, and 96 hours after stimulation. Brain stimulation decreased phagocytic activity of the reticuloendothelial system. These findings may increase our understanding of a possible neural mechanism underlying relationships between stress and resistance to disease states.

This study concerns audiometric evaluation and prediction of hearing loss in the autistic child based on information derived from acoustic reflex thresholds. Two groups (autistic males and normal children) of five subjects each were utilized. Results indicated that the acoustic reflex method consistently predicted significantly higher hearing thresholds for autistic subjects than operant pure-tone audiometric procedures. Furthermore, the acoustic reflex thresholds were significantly less sensitive in the autistic group than in the normal group, suggesting that the acoustic reflex response is somehow altered in autistic individuals. These findings are consistent with earlier work which hypothesized that autistics, manifest an organic brain lesion which interferes with the propagation of auditory information.

Subjects were 38 computer programers employed in a national food-retailing corporation. A job analysis provided a basis for criteria development and served to guide the selection of predictors. Ratings of each programmer's job performance by his immediate supervisor, and scores on such tests as the Computer Programer Aptitude Battery (CPAB), clerical tests, and supervisory judgment test were obtained. Relationships between tests and criteria were examined to find the best test combination for predicting programming performance. Statistical treatment of data included a principal components analysis of the criteria and a multiple linear regression analysis. A weighted combination of the CPAB Reasoning, a test of clerical ability, and supervisory judgment test was found to be highly correlated with performance (R = .60).

Ward environment as assessed by the Ward Atmosphere Scale was the focus of this exploratory study. The Ward Atmosphere scores of 110 patients hospitalized on two units for acute psychiatric care in a state hospital were analyzed for determining differences along the dimensions of population factors, sex and program change. Significant differences in attitude were obtained on certain of the ten scales for each of the three comparisons. The premise of ward atmosphere being a global entity as implied in the literature was not upheld in this population. Sex differences were noted and introduction of an individualized patient management program evoked significant changes in opinions concerning ward atmosphere. A number of interpretations for these results were offered and implication for future research was suggested.

This study considered the relationship between psychopathology and love. Agape love was defined as spontaneous and selfless love. The hypothesis tested was that people demonstrating psychopathology would make fewer positive responses to statements reflecting love than people free of psychopathology. The MMPI was utilized to measure the presence of psychopathology. The Atkinson A Scale (developed for this study) measured agape responses. Both these instruments were administered to 102 subjects in three groups: hospital patients, seminary students, and psychology students. Mean agape scores were subjected to a one-way analysis of variance, Significant difference among the group means was detected at the p <.05 level. A Scheffe test showed hospital patients' agape scores significantly lower than scores of seminary and psychology students. The initial hypothesis was confirmed,

A pre- and postexperimental design with a control group was used to evaluate the effectiveness of a management development program. Subjects were 48 first line staff supervisors employed by a major manufacturing company. The training group subjects (n = 24) attended the company's 1-week training program. Subjects in the control group (n= 24) were similar with respect to plant location, job assignment, etc. A 42-item employee-opinion questionnaire was constructed to measure supervisory style and work.-group climate. The subjects' subordinates (n = 313) completed the questionnaire before and after training. Eleven items identified by content analysis as most relevant to the training content comprised the measure of training effectiveness. An analysis of covariance was performed using the pretest as the covariate. Results indicated no significant training effects.

Behavioral and cognitive skills training for increasing assertive behavior in college students were compared to an equally credible expectancy-control. One significant multivariate function successfully discriminated between the behavioral and control groups, and between the cognitive and control groups. This function was interpreted as showing enhanced behavioral/cognitive construction competencies in the behavioral and cognitive groups. A second function, though not significant, suggested that the cognitive training resulted in more aggressive behavior.

The response deficit following exposure to inescapable shock has been termed "learned helplessness." This experiment was designed (a) to determine whether learned helplessness following an inescapable footshock induction procedure extends to 48 hours, and (b) to test the hypothesis that electroconvulsive shock (ECS) reverses learned helplessness in rats. Subjects were tested for helplessness in a bar-press shock-escape task. Results indicated that helplessness was not present 48 hours after exposure to inescapable shock. A slight indication of helplessness was observed in the first 10 trials of the 60-trial task. In addition, ECS was shown to enhance performance in the test task; however, this facilitation effect was seen only in control animals that were not previously exposed to inescapable footshock.

In order to aid in the understanding of the personality components that contribute to the symptoms of depression, the learning process of persons labeled as depressed was examined. Twenty female subjects who were either receiving or being evaluated for psychotherapy participated in this study. Based on MMPI and DACL scores, 10 depressed and 10 nondepressed subjects were placed in avoidance learning situations. An active avoidance situation required making the correct button press to avoid a sounding buzzer; the absence of the button-pressing response constituted a passive avoidance situation, There was no significant difference between the two groups in learning across avoidance conditions, Depressives were found 'to be less persistent in responding than were nondepressives. Results were explained as supporting a learned helplessness model of depression.

To supplement college introductory statistics instruction, an interactive drill system was developed and implemented on a Hewlett- Packard 2000 timesharing computer. Unlimited practice in basic procedures and algorithms was provided over 38 topics including Chi-square, correlational methods, and one-way analysis of variance. Validation of intermediate computational steps was provided, and more difficult or remedial problems sets were made available. Optional files recorded performance data. Four support programs initialized performance files and generated summary reports. Extensive documentation and a library of reusable subroutines were designed to assist future authors to expand the system. The drill and practice system was made generally available to all university departments and students.

Twenty-one special education children failing to persist after failure on arithmetic problems were given 15 days of treatment in three arithmetic training programs, equivalent in all respects except that success experiences occurred either 46.2%, 76.9%, or 100% of the time. Following training, children in both the 46.2% and 100% reinforcement, groups continued to show serious performance deterioration following failure, while children in the 76.9% group showed marked improvement. An inventory measuring attributions to failure before and after training indicated that the 76.9% reinforcement group showed significantly greater tendency to attribute failure to lack of effort than did either of the other two groups.

The behavior role-playing task (BRPT) has become a popular method of assessing assertive behavior. However, current research suggests that situational factors can affect the outcome of such assessments, independently of the subject's level of assertiveness. The present study investigated the effects of one such factor: the type of prompt delivered during the BRPT. It was hypothesized that subjects would respond more assertively to provocatively prompted scenes than to neutral scenes. Twenty nursing students were exposed to BRPTs involving both provocative and neutral role-player prompts. The results revealed that while provocative BRPTs generated significantly greater amounts of self-reported anger and anxiety than did the neutral BRPTs, there were no significant differences in response latency, duration, or assertive content between the two conditions.
