Relationship of MMPI Profile Clusters to Pain Behaviors (open access)

Relationship of MMPI Profile Clusters to Pain Behaviors

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.

Assassin Syndrome: Threateners Compared to Other Psychiatric/General-Inmate Groups (open access)

Assassin Syndrome: Threateners Compared to Other Psychiatric/General-Inmate Groups

Thirty-seven male prisoners who had been convicted or indicted on a charge of threatening the President or national political figure were compared to state inmates, federal inmates, and normative samples on psychometric and demographic variables. Results indicated that assassin/threateners were significantly more paranoid, schizophrenic, and socially alienated than comparison samples. Their heterosexual adjustment and work record tended to be poorer than comparison inmates. Data suggested that the probability of organic impairment was greater for assassin/threateners than for the normative sample. In addition, political threateners were found to be self-destructive, apolitical, Caucasian, and products of disturbed family backgrounds.

Depression and Learned Helplessness: Task Difficulty and Success-Failure Attribution (open access)

Depression and Learned Helplessness: Task Difficulty and Success-Failure Attribution

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 …

Adolescent Antisocial Behavior, Perceived Parental Behaviors, and Perception of Control (open access)

Adolescent Antisocial Behavior, Perceived Parental Behaviors, and Perception of Control

The study examined the relationships between various parental discipline styles and perceived powerlessness in antisocial adolescents. The literature on adolescent antisocial behavior frequently describes states of disaffection, alienation, and powerlessness as characteristic of the delinquent youth. The parent-child relationship is also frequently implicated as the significant precursor of antisocial behavior in adolescents. The purpose of this study was to determine if perception of control orientations function as cognitive mediators between perceived styles of parental discipline and subsequent behavior in adolescents. It was concluded, on the basis of the data obtained from this study, that antisocial adolescents do not perceive themselves to be more powerless than non-antisocial adolescents. It was recommended that caution should be exercised in applying such a label to those exhibiting antisocial patterns of behavior. It was also concluded that punishment applied in an unpredictable fashion may have detrimental effects on the development of female adolescents.

Biofeedback and Progressive Relaxation in the Treatment of Muscle Tension Headaches: A Comparison (open access)

Biofeedback and Progressive Relaxation in the Treatment of Muscle Tension Headaches: A Comparison

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 Use of Local Norms to Improve Configural Reproducibility of Two MMPI Short Forms (open access)

The Use of Local Norms to Improve Configural Reproducibility of Two MMPI Short Forms

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 …

Life History and Psychometric Personality Factors Differentiating Prisoners Convicted of Violent and Nonviolent Crimes (open access)

Life History and Psychometric Personality Factors Differentiating Prisoners Convicted of Violent and Nonviolent Crimes

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.

Anxiety Relief, Progressive Muscle Relaxation, and Expectancy Relaxation in the Treatment of Speech Phobia (open access)

Anxiety Relief, Progressive Muscle Relaxation, and Expectancy Relaxation in the Treatment of Speech Phobia

Relaxation procedures and anxiety relief were reviewed. Effects of cognitive and expectancy variables in reduction of avoidance behavior were also extensively reviewed. Various theoretical models for desensitization were presented. Use of symbolic control in classical conditioning and use of self-control methods in anxiety reduction were discussed. Special emphasis was given to self-desensitization and cue controlled relaxation. One goal of the experiment was to determine whether a musical stimulus associated with counter anxiety procedures could reduce or prevent subjects' phobic responses in the presence of the phobic situation. Another goal was to determine the relative efficacy of two counter anxiety procedures (anxiety relief and progressive muscle relaxation) in lowering muscle tension and in reducing or preventing speech anxiety. Several implications were drawn from the study. Relaxation alone may alleviate anxiety and phobic behavior without being paired with phobic stimuli. Cognitive variables such as expectancy and feedback of progress make a substantial contribution to treatment of situational anxiety. Progressive muscle relaxation may not be the technique of choice for producing low levels of muscle tension. Recommendations for future research were specified, including additional measures and control procedures.

Female Sexual Orientation: Behavior and Developmental History (open access)

Female Sexual Orientation: Behavior and Developmental History

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.

Treatment of Insomnia in Cancer Patients Using Muscle Relaxation Training (open access)

Treatment of Insomnia in Cancer Patients Using Muscle Relaxation Training

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.

Self-Concept and Verbal Behavior in a Small-Group Social Situation (open access)

Self-Concept and Verbal Behavior in a Small-Group Social Situation

The problem addressed in this exploratory research study was whether any correlational relationship existed between a selection of personality and demographic variables (considered as aspects of the self-concept construct) and selected subjective and objective measurements of verbal behavior. The purpose of the study was to achieve a better understanding of the dynamic monitoring process of the self-concept and the possible relationship that may exist between it and certain quantifiable verbal behaviors. The conclusion of this study is that the self-concept construct does appear to be an influencing factor upon verbal behavior. It is considered that individuals are consistently interacting with their social environment to obtain feedback in order to test the self's perceptions of the social environment and its relationship to its environment.

Self-Disclosure by Mexican-American Women: The Effects of Acculturation and Language of Therapy

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.

Differential Response of Speech-Anxious Repressors and Sensitizers to Systematic Desensitization and Rational-Emotive Therapy (open access)

Differential Response of Speech-Anxious Repressors and Sensitizers to Systematic Desensitization and Rational-Emotive Therapy

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. …

Cigarette Smoking Behavior: Self-Managed Change (open access)

Cigarette Smoking Behavior: Self-Managed Change

In the present study, three self-managed treatment programs were compared with respect to their ability to effect and maintain change in the cigarette smoking behavior of 27 subject volunteers from the population of employees of a Veterans Administration hospital. Subjects were randomly assigned to a self—imposed delay group, a self-directed relaxation group, and a self-monitoring group. The experimental program lasted 6 weeks with a 20-minute individual meeting each week. Three months following treatment, subjects were contacted by mail and were asked to monitor their smoking behavior for one week, and to return their average daily smoking rate by mail. The results provide support for the effectiveness of the self-management technique of self-imposed delay as a durability—enhancing treatment procedure. The effectiveness of self-management techniques as a general class of treatment strategies was not supported. A task for future research would be to establish the effectiveness of the delay technique implemented earlier in the cigarette smoking chain, as well as to determine whether effectiveness is increased or decreased by a specification of the content of a delay interval.

A Comparison of Drug Treatment for Insomnia and the Effect of Causal Attribution

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 …

Localization of Color Discrimination in the Human Cerebral Cortex (open access)

Localization of Color Discrimination in the Human Cerebral Cortex

This study investigated color discrimination as a possible localized function of right or left cerebral hemispheres in humans. Previous studies have shown conflicting results. Studies implicating the left hemisphere have contaminated color discrimination with verbal-symbolic ability. Other studies implicating the right hemisphere emphasized color-matching ability. This study pointed out the importance of response latency as well as accuracy and also the importance of testing the data for meeting the assumptions of the statistical technique utilized. It was concluded that color discrimination is normally a right-hemisphere function in right-handed individuals. Differences in individual ability, although large, were not found to be systematically related to sex or eye dominance, but may be learned individual differences. The study further pointed out the inappropriateness of referring to a major or dominant cerebral hemisphere without stipulating which function is being considered.

Anxiety-Relief Conditioning: An Empirical Investigation (open access)

Anxiety-Relief Conditioning: An Empirical Investigation

The current study investigated the efficacy of Wolpe's original (1954) paradigm of anxiety-relief conditioning. The procedure consisted of administering a mildly aversive electric shock to a subject for several seconds until the subject said the word "Relax," and the shock was terminated. Repeated pairings were claimed by Wolpe to condition physiological relief to the cue word, "Relax," which could then be employed in order to reduce anxiety in various anxiety provoking situations. Since there does not appear to be a generally accepted theoretical rationale to account for the reported efficacy of anxiety-relief conditioning, several theoretical rationales were discussed. In addition, a distinction was made between the anxiety-relief paradigm described by Wolpe (1954) and the aversion-relief paradigm employed by subsequent investigators (Gaupp, Stern, & Galbraith, 1972; Solyom, McClure, Heseltine, Ledwidge, & Solyom, 1972; Thorpe, Schmidt, Brown, & Castell, 1964). It was suggested that this distinction might be used to account for the failure of the current investigation to support the efficacy of anxiety-relief conditioning, as a review of the major study supporting its efficacy (Turnage & Wenrich, 1974) indicated that aversion-relief, rather than anxiety-relief, may have been employed. In the absence of strong supportive evidence for the efficacy of Wolpe's anxiety-relief …

A Comparison of Short-Term Systematic Desensitization and Implosive Therapy under Therapeutic Level of Aspiration (open access)

A Comparison of Short-Term Systematic Desensitization and Implosive Therapy under Therapeutic Level of Aspiration

Systematic desensitization and implosive therapy have surfaced as two of the primary behavioral therapy techniques to decrease phobic responses during the past decade. Although attempts have been made to compare the efficiency and effectiveness of these two techniques, results have been unclear because of the failure of researchers to duplicate the procedures as described by their respective originators. This experiment is designed to explore the joint effects of the therapies and level of therapeutic aspiration. A second objective, and a byproduct of the data produced in achieving the primary objective, was to analyze the goal discrepancy and attainment discrepancy scores accruing throughout the therapy sessions. Several hypotheses were advanced. Further analysis of the three criterion measures by means of ANOVA resulted in significant main sessions effects for each of the three independent analyses. Results suggest that all subjects, regardless of treatment subgroup, did make significant therapeutic gains in their approach scores, fear thermometer scores, and speed of approach scores from the first to the last session. Possible explanations for results were discussed. Furthermore, approach test absolute goal discrepancy, fear thermometer absolute goal discrepancy, approach test absolute attainment discrepancy, and fear thermometer absolute attainment discrepancy scores were calculated for all goal-setting …

Insomnia: Effects of Electromyographic Biofeedback, Relaxation Training, and Stimulus Control

Traditional treatment for insomnia has been chemotherapy-- despite short-term value and side effects. Need for an alternative has led to research on behavioral treatment methods for insomnia. Relaxation training has consistently produced effective results, but the limited research on biofeedback and stimulus control suggests that they too may be viable alternate treatment methods. The present research investigated electromyogram (EMG) biofeedback, pseudo-EMG biofeedback, relaxation, training, and stimulus control as methods of treating sleep-onset insomnia. Volunteers consisting of 12 males and 24 females were recruited through newspaper advertisements. Subjects had no known physical cause for insomnia and were either free of sleeping medication or kept their dosage constant during the study. Subjects were matched for age and sex, randomly assigned to one of the four treatment groups, then randomly assigned to one of three therapists. Results indicated that pretreatment EMG scores for the four groups were high but not significantly different-- while post treatment EMG scores were not significantly reduced. Pretreatment sleep-latency measures were high, but not significantly different from each other. Post treatment latency measures were significantly reduced, but not significantly different from each other. Correlation between EMG-change scores and sleep-latency-change measures was non-significant. Pretreatment nightly awakenings for the four groups …

The Effects of Locus of Control and Soluble Discrimination Problems on Intelligence Test Performance

This study investigated the possible differential effects of a series of soluble discrimination problems on internal versus external locus of control subjects. It was hypothesized that externals exposed to a series of discrimination problems would perform better on a test task than external controls, while internals exposed to the same problems would not perform better on the test task relative to their controls. As anticipated, the internals were not affected by the discrimination problems. However, contrary to expectations, the externals were not facilitated by exposure to the soluble problems. Since many external subjects failed to solve all of the soluble problems, a facilitative effect may depend upon the problems being solved.

The Effects of Selection Risk on Sex Discrimination in Employment Decisions

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.

Learned Helplessness, Attribution, and Clinical Depression

To test predictions of learned helplessness theory and attribution theory, depressed and nondepressed subjects were exposed to a word-association task in a skill, chance, or no-instructional-set condition. Subjects were asked to make attributions of success and failure to four factors--ability, effort, task difficulty, and luck--and rate expectancy of success. The predictions of both theories were only partially confirmed. Difficulties relating to the experimental design may account for the failure of nondepressed/skill subjects to show greater expectancy change. As predicted, all subjects in the chance condition displayed similar expectancy changes. Also as predicted, nondepressed subjects did not rate effort as being the least influential factor. Depressed subjects, however, rated all factors equivalently, instead of rating effort least influential.
