Assessment of thinking style preferences and language proficiency for South African students whose native languages differ

The language proficiency of first-year students at the University of Pretoria (56 men and 59 women, M age=19.40 yr., SD=.80, range from 18.00 to 20.70) was assessed by means of the English Language Skills Assessment. More than one-third of the students did not show proficiency at Grade 10, as expected. This language assessment was not correlated with academic achievement equally well for students in a group. The diversity of thinking style preferences of the students enrolled in a language development course was also assessed on the Herrmann Brain Dominance Instrument. Scores indicated a range of thinking style preferences but the group's overall mean scores represented detail-oriented and feeling-based modes of thinking processes. These preferences were correlated with academic achievement and learning of languages. The data are consistent with the hypothesis that thinking styles could be a focus of educational strategies in South Africa, using the perspective that qualitatively different approaches to teaching might be associated with students' qualitatively different approaches to learning.     

The structure of personality disorders: comparing the DSM-IV-TR Axis II classification with the five-factor model framework using structural equation modeling

Earlier factor analytical studies on the empirical validity of the DSM-IV-TR (American Psychological Association, 2000) Axis II classification have offered little support for the current three-cluster structure. In his large-scale meta-analysis of previously published personality disorder correlation matrices, O'Connor (2005) found four factors, corresponding to the neuroticism, extraversion, agreeableness, and conscientiousness domains of the five-factor model of personality. In the present study, this dimensional four-factor model and the categorical DSM three-cluster structure were fitted to the Assessment of DSM-IV Personality Disorders questionnaire (ADP-IV; Schotte & De Doncker, 1994) scale scores using structural equation modelling. The results strongly favored the dimensional model, which also resembled other well-founded four-factor proposals (Livesley, Jang, & Vernon, 1998; Widiger & Simonsen, 2005). Moreover, a multigroup confirmatory factor analysis showed that this model was highly invariant and thus generalizable across two large clinical (n = 1,029) and general population (n = 659) samples.     

Irrational Beliefs in Employees with an Adjustment,a Depressive,or an Anxiety Disorder: a Prospective Cohort Study

It remains unclear if patients with different types of common mental disorders, such as adjustment, anxiety and depressive disorders, have the same irrational ideas. The aim of this prospective cohort study (n = 190) is to investigate differences in level and type of irrational beliefs among these groups and to examine whether a change in irrational beliefs is related to symptom recovery. Irrational beliefs (IBI) and symptoms were measured at four points in time: at baseline, after 3, 6 and 12 months. Results showed that diagnostic groups differed in their level of irrational beliefs and this effect remained over time. Highest levels of irrationality were observed in the double diagnosis group, followed by the anxiety disorder group and the depression group. Participants with adjustment disorders showed the lowest levels of irrationality, comparable to a community sample. We did not find differences in the type of irrational beliefs between diagnostic groups. The level of irrationality declined over time for all diagnostic groups. No differences in decrease were observed between diagnostic groups. The magnitude and direction of change in irrational beliefs were related to the magnitude of recovery of depressive, anxiety and stress symptoms over time. These results support the application of general cognitive interventions, especially for patients with a depressive or an anxiety disorder.     

Taskomat: Evaluation of a Computerized Test Battery

A case study on a computerized test battery is presented based on more than a decade of use in military and civil settings. The study sheds light on the general issues associated with computerized testing. The accent is on the contrast between computerized and traditional paper-and-pencil testing. The computerized battery, called Taskomat, is founded on concepts arising from human performance theory. The tests of the battery are described, as well as issues related to the hardware (cost of purchasing, hardware reliability and industrial styling). Criteria used to evaluate the content of the tests were: reliability, robustness of effects, uniqueness or newness of abilities relative to paper-and-pencil testing, and validity of these abilities for predicting occupational success. A conclusion is that a theoretical foundation helps to increase the likelihood of assessing new abilities.     

Application of a simple recording system to the analysis of free-play behavior in autistic children

An observational system, which has been developed to facilitate recording of the total behavioral repertoire of autistic children, involves time-sampling recording of behavior with the help of a common Stenograph machine. Categories which exhausted all behavior were defined. Each category corresponded with a designated key on the Stenograph machine. The observer depressed one key at each 1-sec interval. The observer was paced by audible beats from a metronome. A naive observer can be used with this method. The observer is not mechanically limited and a minimum of observer training is required to obtain reliable measures. The data sampled during a five-week observation period indicated the stability of a taxonomic instrument of behavior based upon direct, time-sampling observations and the stability of spontaneous autistic behavior. Results showed that the behavior of the subjects was largely nonrandom and unsocialized in character.     

Would we rather lose our life than lose our self? Lessons from the Dutch debate on euthanasia for patients with dementia

This article reviews the Dutch societal debate on euthanasia/assisted suicide in dementia cases, specifically Alzheimer's disease. It discusses the ethical and practical dilemmas created by euthanasia requests in advance directives and the related inconsistencies in the Dutch legal regulations regarding euthanasia/assisted suicide. After an initial focus on euthanasia in advanced dementia, the actual debate concentrates on making euthanasia/assisted suicide possible in the very early stages of dementia. A review of the few known cases of assisted suicide of people with so-called early dementia raises the question why requests for euthanasia/assisted suicide from patients in the early stage of (late onset) Alzheimer's disease are virtually non-existent. In response to this question two explanations are offered. It is concluded that, in addition to a moral discussion on the limits of anticipatory choices, there is an urgent need to develop research into the patient's perspective with regard to medical treatment and care-giving in dementia, including end-of-life care.     

Illness Identity in Adults with a Chronic Illness

The present study examines the concept of illness identity, the degree to which a chronic illness is integrated into one’s identity, in adults with a chronic illness by validating a new self-report questionnaire, the Illness Identity Questionnaire (IIQ). Self-report questionnaires on illness identity, psychological, and physical functioning were assessed in two samples: adults with congenital heart disease (22–78 year old; n?=?276) and with multisystem connective tissue disorders (systemic lupus erythematosus or systemic sclerosis; 17–81 year old; n?=?241). The IIQ could differentiate four illness identity states (i.e., engulfment, rejection, acceptance, and enrichment) in both samples, based on exploratory and confirmatory factor analysis. All four subscales proved to be reliable. Rejection and engulfment were related to maladaptive psychological and physical functioning, whereas acceptance and enrichment were related to adaptive psychological and physical functioning. The present findings underscore the importance of the concept of illness identity. The IIQ, a self-report questionnaire, is introduced to measure four different illness identity states in adults with a chronic illness.
