Accelerated EMG Biofeedback Relaxation Training and Tension Headache: The Effects of Home Practice and Headache Presence During Training (open access)

Accelerated EMG Biofeedback Relaxation Training and Tension Headache: The Effects of Home Practice and Headache Presence During Training

This study investigated the value of headache presence during elecromyographic (EMG) feedback relaxation training and the contribution made by home relaxation practice in the elimination of tension headache. Eighteen participants, mainly coeds in their twenties, recorded headache and medication data for two baseline weeks, and were assigned to one of three training groups. Group A received EMG feedback training with headache presence during the session and home relaxation practice. Group B received EMG feedback without headache Presence and home practice. Group C received only home relaxation practice. Statistically significant treatment differences were not found, but declining trends of headache activity and medication use tend to support the efficacy of EMG training with headache presence.

Accurate Empathy and Rorschach Interpretation (open access)

Accurate Empathy and Rorschach Interpretation

Although the Rorschach is one of the most widely used psychological assessment techniques, its empirical support has been equivocal. One possible explanation for this lack of empirical support is the tendency for researchers to study only the assessment tool with little regard for the clinician using it. The current study examined one clinician variable (empathy) and its relationship to accuracy of interpretation of the Rorschach. The literature regarding Rorschach theory and research and empathy theory and research was reviewed in an attempt to clarify the similarities between empathy as an important factor in psychotherapy and its importance in the assessment process. The present study measured empathy by using the Davis Empathy Questionnaire and a Taped Excerpt Response Measure.

Adherence/Compliance to Exercise Prescription: A Test of the Self-Efficacy Model (open access)

Adherence/Compliance to Exercise Prescription: A Test of the Self-Efficacy Model

It has been well-documented in the literature that there are many physical and psychological benefits to be derived from regular aerobic exercise. It has also been noted that adherence/compliance to aerobic exercise regimens tends to be quite low. Investigators have found that a number of factors tend to correlate with adherence, but it has been difficult thus far to determine a mechanism which underlies a tendency to adhere versus a tendency to drop-out. This study examined the problem of non-adherence from the perspective of Self-Efficacy Theory (Bandura, 1977). Subjects for this investigation included all patients seen during a four week period in the Cooper Clinic at the Aerobics Center in Dallas, Texas. Patients at the clinic receive a complete physical examination and health prescriptions based upon the results of their examination. During this four week period, half were administered a Self-Efficacy Questionnaire. Approximately three months later all patients seen during this four week period received a followup (adherence questionnaire in the mail). It was hypothesized that there would be a positive relationship between responses on the Self-Efficacy Questionnaire and responses on the Adherence Questionnaire. A second hypothesis stated that there would be a positive relationship between items which specifically pertained …

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.

Adolescent Self-Mutilating Behaviors: Experiential Avoidance Coupled with Imitation? (open access)

Adolescent Self-Mutilating Behaviors: Experiential Avoidance Coupled with Imitation?

Repetitive self-mutilation (RSM) has become increasingly prevalent among adolescents. Empirical research has pinpointed several correlates of this behavior, but the initiation and maintenance of RSM among adolescents are not well understood. The experiential avoidance model (EAM) proposes that self-mutilation is a behavior that allows for the avoidance or alteration of unwanted internal experiences, and that it is negatively reinforced with repetition. The current study explored the usefulness of the EAM as an explanatory theory for adolescent RSM, with the additional incorporation of issues of social context. Adolescents (N = 211) from three school-based samples completed self-report questionnaires. One-third of students reported at least one incident of purposeful, non-suicidal self-mutilation and 16% had engaged in self-mutilation repeatedly within the past 6 months. Both regression and group analyses indicated that adolescents who engage in RSM report greater psychological distress, a greater incidence of functionally equivalent behaviors, and greater exposure to self-mutilation among peers and/or in the media, when compared to their counterparts who have not engaged in RSM. Suicidal ideation/behaviors were consistently the strongest predictors of current self-mutilation behaviors. Clinical implications, limitations, and suggestions for future research are discussed.

Affective Forecasting: the Effects of Immune Neglect and Surrogation (open access)

Affective Forecasting: the Effects of Immune Neglect and Surrogation

Studies of affective forecasting examine people’s ability to predict (forecast) their emotional (affective) responses to future events. Affective forecasts underlie nearly all decisions people make and the actions they take. However, people engage in systematic cognitive errors when making affective forecasts and most often overestimate the intensity and duration of their emotional responses. Understanding the mechanisms that lead to affective forecasting errors (e.g., immune neglect) and examining the utility of methods for improving affective forecasting errors (e.g., surrogation) can provide highly valuable information for clinicians as they assist clients in determining their goals both for therapy and for life. The first purpose of the current study was to determine if affective forecasting errors due to immune neglect lead to misjudgments about the relative emotional impact of minor versus moderate negative experiences (i.e., trauma severity). The second purpose was to examine the utility of surrogation for improving affective forecasts. Potential interaction effects between these two variables were also examined. The current study utilized a 2 (Trauma Severity: minor, moderate) X 3 (Prediction Information: surrogation information only, simulation information only, both types of information) experimental design. Undergraduates were recruited via the SONA system and randomly assigned to one of the six experimental …

Affective Reactions and Psychosocial Functioning in the Course of Psycho-Educational Assessment (open access)

Affective Reactions and Psychosocial Functioning in the Course of Psycho-Educational Assessment

Every day, children throughout the United States are given psychological evaluations for many different clinical and psycho-educational purposes. Very little research has attempted to investigate children's responses to the experience of having intellectual and achievement tests administered. The goal of the current research was to explore the effect a psycho-educational evaluation has on children in areas of self-concept and anxiety. Dependent variables consisted of pre- and post-test measures of anxiety and self-concept. A total of 75 children in the 4th 5th and 6th grades were recruited after referral for evaluation and possible placement in the Talented and Gifted Program or Special Education. This study employed Analysis of Variance (ANOVA), t-tests, multiple regression analysis, and correlational analysis. Findings included initial evidence that children endorsed decreased anxiety after psycho-educational assessments rather than increased anxiety, suggesting that fear of unknown situations may be more anxiety provoking than the actual situation itself, potentially beneficial findings for psychology and psychometric professionals who evaluate children daily. Students endorsement of academic self-concept significantly predicted anxiety after a psycho-educational evaluation, indicating that students who feel capable in academic areas may endorse less anxiety after an evaluation than students who do not feel academically capable. Finally, negative verbal interaction …

Allergen Research and Its Implications for Psychology: History, Current Status, and Prospectus (open access)

Allergen Research and Its Implications for Psychology: History, Current Status, and Prospectus

The purpose of this manuscript was to present a brief history, the current status, and a prospectus of allergen and allergic reactions. Research on allergic reactions, particularly as viewed from the psychogenic position, was presented. The review strongly suggests that the psychogenic orientation has been frought with contradictions, unnecessarily complex interpretations, and an over-abundance of subjective, dynamic, and analytic redundancies which have done little more than perpetuate the stagnation of a rather important subdomain of the "mental" health professions.

Altruism and Depression: Exploring This Relationship and the Mechanisms Behind It (open access)

Altruism and Depression: Exploring This Relationship and the Mechanisms Behind It

The impact of environmental influences on depression has been well established by research. In particular, it is known that receiving/perceiving adequate social support has a protective influence on depression. Less is known about the protective benefits of providing support to others, namely in the form of altruistic, empathetic, or prosocial behavior. While research has shown that having altruistic attitudes and engaging in altruistic behaviors has a positive impact on physical health and mental well-being, studies on the association between altruistic attitudes and/or behavior and depression are limited. The present study examined the relationship between altruism and depression, and hypotheses were tested that allow for explanation of why altruism may protect against depression. A sample of 303 participants was recruited from the University of North Texas and the surrounding community. Participants completed an online survey that examined their altruistic activities, details regarding these activities, their prosocial attitudes, and their current level of depression. Results did not support that level of involvement in altruistic activities is directly related to depression severity. However, outcomes from involvement in altruistic activities, including sense of overburden from participating in altruistic activities, level of social interaction with other helpers and those helped during altruistic activities, and sense …

Anger/Hostility: Reliability of Measurement and Correlates of Health History (open access)

Anger/Hostility: Reliability of Measurement and Correlates of Health History

The purpose of this study was to (1) assess the reliability and validity of anger/hostility measures, (2) examine the relationship between anger/hostility and other negative emotions, and (3) examine the relationship between anger/hostility and health history. Sixty-five subjects were given the Buss Durkee Hostility Inventory (BDHI), the State-Trait Anger Expression Inventory (STAXI), the Profile of Mood States pomsS), the Clinical Analysis Questionnaire (CAQ), the State-Trait Anxiety Inventory (STAI), the Health and Wellness Attitude Inventory (HWAI), and a health questionnaire designed to provide information about past disease and alcohol/drug use. Overall, the BDHI and POMS displayed good test-retest reliability. All six of the global indices of anger/hostility intercorrelated at a significant level, thus demonstrating good concurrent validity. The six global measures of anger/hostility also correlated at a significant level with other negative emotions.

Anxiety-Management Training for the Reduction of Type A Coronary-Prone Behavior (open access)

Anxiety-Management Training for the Reduction of Type A Coronary-Prone Behavior

The present study investigated the effects of anxiety management training on the reduction of Type A coronary-prone behavior in a college student population and utilized behavioral measures as well as self-report indices of change. Evaluations pre- and post-treatment included self-report measures of Type A behavior, empirically validated performance measures of the achievement-striving and time-urgency components of coronary-prone behavior, and a learned helplessness manipulation that has been associated with this behavior pattern. Analysis of covariance indicated that the treatment group changed in the desired direction on all self-report indices, and on most of the performance measures and helplessness scores that were used as dependent variables. Discussion centered on the implications of these data to theoretical and practical conceptualizations of coping behavior and coronary disease and cautions were expressed concerning clinical significance, maintenance, and generalization of results.

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 …

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.

The Applicability of the PICTS-SV in Offenders with Severe Substance Use Histories (open access)

The Applicability of the PICTS-SV in Offenders with Severe Substance Use Histories

Two important developments are addressed by this dissertation. First, the Psychological Inventory of Criminal Thinking Styles-Simplified Version (PICTS-SV) was examined in relation to the original PICTS. Second, the vulnerability of the PICTS-SV to intentional risk minimization (RM) was tested. Two separate studies recruited a total of 150 offenders from a court-mandated residential substance use treatment facility. As expected, Study I established the PICTS-SV's good concurrent validity with the PICTS, especially at the broad composite scale level. For Study II, criminal thinking failed to show the anticipated convergence with HCR-20 risk classifications or forensic correlates. Potential explanations, including a restricted range of risk levels in this sample, are discussed. As a particular strength, the findings highlight that the PICTS-SV, in contrast to many risk measures, displays robust resistance to RM distortion, although revisions to its Df-r validity scale are warranted. These results overall demonstrate strong evidence of the PICTS-SV's utility for assessing a dynamic criminogenic need to inform effective interventions and accurate risk determinations.

Application of a Non-Speech Response Mode in Teaching Simple Language Functions to Three Autistic Children

A non-speech response mode similar to the one used by Prepack (1971) to teach language to a chimpanzee was utilized to teach two simple language functions to three autistic children. The response mode consisted of picking up a geometric symbol and placing it on a response tray. The geometric symbol was the basic unit in this language system. The symbols were used to represent objects in the environment and relationships between the objects.

Are Deficits in Mindfulness Core Features of Borderline Personality Disorder? (open access)

Are Deficits in Mindfulness Core Features of Borderline Personality Disorder?

Mindfulness is a core component of dialectical behavior therapy (DBT), a widely utilized treatment for borderline personality disorder (BPD); however, the import of mindfulness in treating BPD has yet to be demonstrated, and the relationship of mindfulness to BPD constructs is unclear. The current study utilized structural equation modeling to examine the relations of mindfulness with BPD features and the underlying constructs of interpersonal problem-solving effectiveness, impulsivity, emotion regulation strategies, and neuroticism in 342 young adults. Mindfulness was significantly related to effectiveness in interpersonal problem-solving, impulsivity and passivity in emotion regulation, and borderline features. Furthermore, mindfulness continued to predict borderline features when controlling for interpersonal problem-solving and impulsive/passive emotion-regulation strategies, as well as when controlling for neuroticism. It is concluded that difficulties with mindfulness may represent a core feature of BPD and that improvement in mindfulness may be a key component of treatment efficacy with BPD. It is recommended that the unique contribution of mindfulness be investigated in future treatment-outcome research.

Are You a Good Witch or a Bad Witch? The Importance of Object Relations in Modern Assessment (open access)

Are You a Good Witch or a Bad Witch? The Importance of Object Relations in Modern Assessment

The Social Cognition and Object Relations Scale—Global (SCORS-G) is a relatively new scoring system for the Thematic Apperception Test (TAT) that provides information about an individual's functioning in a variety of domains, including intrapsychic and interpersonal. Participants in this archival study had been administered a variety of measures as part of a routine clinical assessment, including the TAT, Rorschach, Minnesota Multiphasic Personality Inventory-2, and the Wechsler Adult Intelligence Scale. Selected TAT stories were rescored using current SCORS-G scoring criteria. This dissertation evaluated the factor structure of the SCORS-G in an outpatient sample with a principal component analysis (PCA), finding support for a two-component solution. The SCORS-G was then compared to well-established measures of personality functioning, social cognition, and object relations using correlational analyses, with mixed results. Lastly, support was found for using the SCORS-G as a tool for discriminating individuals with a history of violent or problematic relationships from those without such a history. Implications for card selection based on card pull and the impact of bland protocols were explored.

Assessing the Object Relations of Sexually Abused Females (open access)

Assessing the Object Relations of Sexually Abused Females

The TAT stories of 38 sexually abused females between the ages of 5 and 18 years and a clinical group of 26 females with no recorded history of abuse were analyzed using the Object Relations and Social Cognitions TAT Scoring System (Westen et al., 1985). Subjects in the sexual abuse group showed significantly lower mean scores on a scale measuring affect-tone of relationship paradigms and on a scale measuring complexity of representations of people. In addition, pathological responses were given significantly more often by sexual abuse victims on the complexity of representations of people scale. Thus, sexually abused children showed more primitive and simple characterizations of people and more negative, punitive affect in their representations. Moreover, these results were independent of age, race, and intelligence. Group differences are discussed in terms of object relations development.

Assessment Center Ratings as a Function of Personality Factors, Sex and Rating System

The purpose of this study was to examine the differences between the traditional global rating scale and a new behavioral rating scale in a university-based assessment center. It was hypothesized that personality factors, as measured by the 16PF and associated with the global ratings of performance would differ from those associated with the behavioral ratings of performance. It was further hypothesized that the associated personality factors would also differ for males and females. These hypotheses were ^confirmed. Pearson correlations were computed for ratings of males, females, and all subjects combined on both global and behavioral rating scales.

The Assessment of Cognitive Functioning among Patients with Unilateral Visual Neglect: Effects of Field of Presentation and Cueing (open access)

The Assessment of Cognitive Functioning among Patients with Unilateral Visual Neglect: Effects of Field of Presentation and Cueing

Prior evidence has shown a reduction of neglect on line bisection tasks as a function of altered hemispace presentation and left cueing. The present study was conducted to examine the effect of these factors in reducing symptoms of neglect on measures of general cognitive functioning. To examine proposed changes, revised versions of the Raven's Coloured Progressive Matrices and the Memory-for-Designs (MFD) Test were constructed by placing the target stimuli in the right hemifield. Two experimental presentations, a right hemispace condition and a right hemispace plus left cue prompt condition, were compared to the standard presentation format. The primary hypotheses predicted that RBD neglect patients would reveal enhanced performance on the criterion measures as a result of these manipulations. Significant correlations were predicted between the neglect measures and between the two scoring systems for the MFD. The sample was comprised of 54 hospitalized patients, assigned to either a RBD neglect group (N = 18), a RBD nonneglect group (N = 18) , or an orthopedic control group (N = 18) . Both RBD groups were administered the Mini Inventory of Right Brain Injury, to document the presence and severity of right brain injury. Presence of neglect was assessed via the Schenkenberg …

Assessment of Cognitive Performance in Mixed Martial Arts Athletes (open access)

Assessment of Cognitive Performance in Mixed Martial Arts Athletes

Incidents and awareness of sports-related concussion have grown in recent years, attracting attention in both the academic and popular press. These concussions can lead to the rapid onset of neurological dysfunctions, as well as a variety of subjective symptoms. Although concussive sequelae are typically considered transient, debate remains about the persistent effects of repeated traumatic contact during sport participation. Although research has examined the complications of head trauma found in traditionally popular sports (e.g., football, soccer, boxing), little research has focused on the growing sport of mixed-martial-arts (MMA). Research specifically pertaining to MMA is in nascent stages, but to-date studies suggest that concussive injuries for this sport are prevalent and the training regimens of these athletes may place them at a high risk for concussive or subconcussive head traumas—as well as the accompanying neurological difficulties. The current study is the first to assess cognitive profiles of MMA athletes using an objective neuropsychological assessment instrument. Among 56 athletes (28 MMA athletes and 28 athletes not exposed to head traumas), no neuropsychological differences were found between groups of athletes. Additionally, no aspects of MMA training regimen shared a reliable relationship with neuropsychological performance or subjective concussive symptoms. This suggests non-professional participation in …

Assessment of Competencies among Doctoral Trainees in Psychology (open access)

Assessment of Competencies among Doctoral Trainees in Psychology

The recent shift to a culture of competence has permeated several areas of professional psychology, including competency identification, competency-based education training, and competency assessment. A competency framework has also been applied to various programs and specialty areas within psychology, such as clinical, counseling, clinical health, school, cultural diversity, neuro-, gero-, child, and pediatric psychology. Despite the spread of competency focus throughout psychology, few standardized measures of competency assessment have been developed. To the authors' knowledge, only four published studies on measures of competency assessment in psychology currently exist. While these measures demonstrate significant steps in progressing the assessment of confidence, three of these measures were designed for use with individual programs, two of these international (i.e., UK and Taiwan). The current study applied the seminal Competency Benchmarks, via a recently adapted benchmarks form (i.e., Practicum Evaluation form; PEF), to practicum students at the University of North Texas. In addition to traditional supervisor ratings, the present study also involved self-, peer supervisor, and peer supervisee ratings to provide 360-degree evaluations. Item-response theory (IRT) was used to evaluate the psychometric properties of the PEF and inform potential revisions of this form. Supervisor ratings of competency were found to fit the Rasch model …

Assessment of Feigned Neurocognitive Impairment in Retired Athletes in a Monetarily Incentivized Forensic Setting

Compromised validity of test data due to exaggeration or fabrication of cognitive deficits inhibits the capacity to establish appropriate conclusions and recommendations in neuropsychological examinations. Detection of feigned neurocognitive impairment presents a formidable challenge, particularly for evaluations involving possibilities of significant secondary gain. Among specific populations examined in this domain, litigating mild traumatic brain injury (mTBI) samples are among the most researched. One subpopulation with potential to contribute significantly to this body of literature is that of retired athletes undergoing fixed-battery neuropsychological evaluations within an assessment program. Given the considerable prevalence of concussions sustained by athletes in this sport and the substantial monetary incentives within this program, a unique opportunity exists to establish rates of feigning within this population to be compared to similar forensic mTBI samples. Further, a fixed battery with multiple validity tests (VT) offers a chance to evaluate the classification accuracy of an aggregated VT failure paradigm, as uncertainty abounds regarding the optimal approach to the recommended use of multiple VTs for effort assessment. The current study seeks to examine rates of feigned neurocognitive impairment in this population, demonstrate prediction accuracy equivalence between models based on aggregated VT failures and logistic regression, and compare classification performance of …
