Cluster Analysis of the MMPI-2 in a Chronic Low-Back Pain Population (open access)

Cluster Analysis of the MMPI-2 in a Chronic Low-Back Pain Population

The Minnesota Multiphasic Personality Inventory (MMPI) is the most frequently used psychological measure in the assessment of chronic pain. Since the introduction of the MMPI-2 in 1989 only two published studies have focused on cluster analysis of chronic pain patients. This study investigated MMPI-2 cluster solutions of chronic low-back pain patients. Data was collected from 2,051 chronic low-back pain patients from a multidisciplinary pain clinic in the southwestern United States. A hierarchical clustering procedure was performed on K-corrected T-scores of the MMPI-2 using the three validity and ten clinical scales. Four relatively homogeneous subgroups were identified for each sex with the MMPI-2. In general, these results replicated the findings of previous researchers using both the MMPI and MMPI-2.

Comparing Quality of Life: American and Portuguese Cancer Patients with Hematological Malignancies (open access)

Comparing Quality of Life: American and Portuguese Cancer Patients with Hematological Malignancies

The purpose of this study is to investigate the differences and similarities of quality of life (QoL) in American and Portuguese cancer patients with hematological malignancies as well as the robustness of the measures cross-culturally. Portuguese participants were 98 patients and 49 accompanying persons and the American participants were 55 patients and 22 accompanying persons. Fifty (Portuguese sample) to 40% (American sample) of the patients came with an accompanying person who answered the questionnaire concerning the patient's QoL. The two cultural groups were characterized in terms of QoL (measured by the SF-36 and the FLIC), social support (Social Support Scale), socio-demographic and clinical variables. Portuguese patients reported a higher QoL. However, this result could be attributable to the fact that the two cultural samples differ in socio-economic status. The measures seem to be comparable for the Portuguese and American samples, at least in what concerns reliability and concurrent validity.

Comparing the Personal Lives of Psychotherapists and Research Psychologists (open access)

Comparing the Personal Lives of Psychotherapists and Research Psychologists

Although the personal life of the therapist has been a topic of interest for nearly sixty years there is still a paucity of research in this area. There is also a lack of research into the personal lives of researcher psychologists. In this study 282 psychologists (151 researchers and 131 therapists) who attended regional meetings and seminars sponsored by professional psychological associations in Texas were sampled. Job stressors, personal problems and health concerns, relaxation techniques, life satisfaction, and work impact on personal life were some of the areas examined. The most important stressors associated with research were excessive teaching responsibilities, pressures associated with funding and lack of time for a personal life. For therapists the most important stressors associated with work were suicide attempts by clients, clients showing resistance, and clients being angry. Therapists reported more concerns related to anxiety, depression, and family problems than researchers. Both groups chose exercise/sports and movies/television as their most common methods for relaxation. Therapists were three times more likely to have been in therapy than researchers and once in therapy reported six times the number of hours. Researchers reported less childhood abuse than therapists. However, therapists were more satisfied with their current life, indicating …

Compulsive Sexual Behavior and Personality Characteristics : A Comparative Analysis (open access)

Compulsive Sexual Behavior and Personality Characteristics : A Comparative Analysis

The purpose of the present study was to compare the scores of the Beck Depression Inventory, State-Trait Anxiety Inventory, and the Coopersmith Inventory of heterosexual men with compulsive sexual behavior (N = 22), homosexual men with compulsive sexual behavior (N = 19), heterosexual men without compulsive sexual behavior (N = 38), and homosexual men without compulsive sexual behavior (N = 8). The Sex Addiction Screening Test was used to determined placement in a group. Findings revealed men who exhibit compulsive sexual behavior are significantly more depressed, experience lower self-esteem and have higher state anxiety (situational) than controls.

Detection of Malingering on Raven's Standard Progressive Matrices and the Booklet Category Test (open access)

Detection of Malingering on Raven's Standard Progressive Matrices and the Booklet Category Test

The capacity of Raven's Standard Progressive Matrices (SPM) and the Booklet Category Test (BCT) to discriminate between groups of brain-injured, simulated malingering, and normal participants was investigated in this study. Exploratory analyses were also conducted to examine the differences between groups categorized as sophisticated and naive fakers. Clinical decision rules and discriminant function analyses were utilized to identify malingerers. Clinical decision rules ranged in hit rates from 41% to 78%, in sensitivity from 2% to 100%, and in specificity from 86% to 100%. Discriminant functions ranged in hit rates from 81% to 86%, in sensitivity from 68% to 73% and in specificity from 82% to 87%. Overall, the least helpful detection method examined was below chance responding on either measure, while the most efficient was gross errors for SPM.

Differences in Parenting Stress Between Parents of Children with ADHD, Children with Internalizing Behavior Problems, and Non-Referred Children (open access)

Differences in Parenting Stress Between Parents of Children with ADHD, Children with Internalizing Behavior Problems, and Non-Referred Children

Recently, researchers have begun to explore the associated impacts of ADHD on parent and family functioning, with an increasing focus on parenting stress. Accumulating empirical evidence is mixed, suggesting that parents of children with ADHD report increased levels of parenting stress when compared to parents of children with learning disabilities, and parents of non-referred children, but report equally stressful parenting levels when compared to parents of children with externalizing behavior problems. Results of the present study comparing reported parenting stress levels between parents of children with ADHD, children with internalizing behavior problems, and nonreferred children, were partially supportive of results found in past studies indicating higher levels of parenting stress among parents of children with ADHD. However, strong gender effects were found between mothers and fathers, which mediated the overall results.

Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes (open access)

Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes

Much research has been undertaken to determine how Subject Matter Expert characteristics affect job analysis outcomes. The current study seeks to discover if performance levels are related to current incumbents ratings of their positions. A group of 114 corporate associates, from two administrative positions, served as Subject Matter Experts (SME) for this study. Separate job analyses for each position were conducted using the Job Analysis Task Checklist. The results for each job were analyzed to determine if SME performance levels affected job analysis outcomes. The results for both jobs showed that there were very few differences in job analysis results as a function of SME performance levels.

External and Internal Influences on Congruence Between Sexual Attitudes and Behavior (open access)

External and Internal Influences on Congruence Between Sexual Attitudes and Behavior

The purpose of this study was to examine the hypotheses that the external factors of family environment, gender, and clinical status and the internal factors of self-esteem and impression management would have either a positive influence or a negative influence on individuals' congruence between their sexual attitudes and their sexual behavior. The hypotheses that the external and internal factors would be significant predictors of congruence between sexual attitudes and behavior were not supported by regression analyses. Clinical status and impression management were significant predictors of congruence but in the opposite direction than hypothesized. When age was factored out of the regression equation, clinical status was no longer a significant predictor of congruence. However, impression management remained a significant predictor of congruence.

Hemispheric Interactions and Event-Related Potentials in Lateralized Stroop and Stroop Analog Tasks (open access)

Hemispheric Interactions and Event-Related Potentials in Lateralized Stroop and Stroop Analog Tasks

Classical Stroop stimuli and newly developed face/word Stroop analog stimuli were used to investigate hemispheric interactions in Stroop interference effects (SEs) and corresponding event-related potentials (ERPs). Lateralized stimuli were presented unilaterally and bilaterally as congruent or incongruent color strip-word or face-word pairs (to invoke right hemisphere (RH) and left hemisphere (LH) specialization, respectively, in the latter case). The common finding for such tasks is that responses for the congruent condition are faster and more accurate than for the incongruent condition (i.e., the SE). A primary prediction is that the SE will be maximized when both the distractor and target components, or distractor alone, are presented to the specialized hemisphere (i.e., LH for words and RH for faces). A total of 88 right-handed University of North Texas students participated in one of four experiments. Participants manually responded to one component of the stimuli (i.e., color, face, or word), while ignoring the other. Behaviorally, participants showed a robust SE across all experiments, especially for the face/word task with word targets. Findings from the face/word Stroop analog tasks also indicated that SEs were produced by selective attention to either faces or words, implicating a role for top-down (controlled) processes. Hemispheric asymmetries were observed …

The Process of Sharing Team Leadership : A Study of Key Leadership Behaviors and Who Exhibits Them

Using a manufacturing setting that is organized into self-managed teams, the current study identified and measured key leadership behaviors within the teams. Questions that were asked include: are some team leadership behaviors more critical to a team's level of functioning than other behaviors? and do successful self-managed teams rely on formal leadership to a lesser extent than members of less successful teams? These questions were asked in the context of leadership as a process, not an individual.

The Relationship between Hardiness and Responses to Life Events in Adulthood (open access)

The Relationship between Hardiness and Responses to Life Events in Adulthood

The relationship between psychological hardiness and individuals' coping with two life events, involuntary job loss and post-parental launching of adolescent children, was investigated in a sample of 146 adults, 83 of which had experienced job loss and 61 of which had experienced the empty nest. Volunteers completed questionnaires which measured hardiness, distress, coping strategies, neuroticism, and extraversion. Multivariate analyses were performed, both with and without covariates, for overall hardiness as well as the hardiness subscales of control, commitment, and challenge. Significant hardiness by life event interactions on escape-avoidance coping were found in both sets of analyses. Main effects for hardiness, however, disappeared when controls for neuroticism and extraversion were utilized. Findings underscore the necessity of employing neuroticism controls in future hardiness research.
