- Description: This study explored whether scores on intelligence tests and personality questionnaires can predict performance in an adult basic education and training (ABET) programme. Participants in ABET programmes often have limited English reading skills, which make the use of conventional assessment tools problematic. A proposed solution is to utilise instruments that make limited demands on the use of language. Raven’s Progressive Matrices (RPM), a well-established intelligence test, and the Five Factor-Nonverbal Personality Questionnaire (FF-NPQ) are both instruments that do not require any reading. The performance of 82 participants in the practical and academic components of an ABET programme was correlated with the RPM and the five traits of the FF-NPQ, namely, Extraversion, Conscientiousness, Openness to Experience, Neuroticism and Agreeableness. The RPM correlated significantly with both the practical (r = 0.47) and academic components (r = 0.35). The Agreeableness scale of the FF-NPQ correlated significantly with the practical component (r = 0.34). No personality scale correlated significantly with the academic component. The results show that non-verbal intelligence tests and personality inventories can be potentially useful in the prediction of performance in an ABET programme.

- Description: The factor structure of the Edinburgh Postnatal Depression scale (EPDS) and similar instruments have received little attention in the literature. The researchers set out to investigate the construct validity and reliability of the EPDS amongst impoverished South African women. The EPDS was translated into isiXhosa (using Brislin’s back translation method)and administered by trained interviewers to 147 women in Khayelitsha, South Africa. Responses were subjected to maximum likelihood confirmatory factor analysis. A single factor structure was found, consistent with the theory on which the EPDS was based. Internal consistency was satisfactory (a = 0.89).

- Description: This article describes the development of the Sources of Work Stress Inventory (SWSI). Factor analyses of the generated items produced (a) a General Work Stress Scale and (b) eight Sources of Work Stress scales, namely Bureaucracy/Autonomy, Relationships, Tools and Equipment, Workload, Role Ambiguity, Work/Home Interface, Job Security and Career Advancement. Rasch rating scale analyses supported the construct validity and reliability of the scales. A multiple regression analysis confirmed the expected strong relationship between the different sources of work stress and the experience of stress in the workplace. It is concluded that the SWSI shows promise as a measure of work stress in the South African context.

Examining the cheats: the role of conscientiousness and excitement seeking in academic dishonesty.

- Description: This study examines the relationships of the personality traits of conscientiousness and excitement seeking with self-reported frequency of premeditated cheating in tests and exams among university students. The results show that the two traits combine to account for a statistically and practically significant proportion of variance in academic cheating. It appears that a lack of effort and a need for high excitement seeking may serve as predisposing traits with regard to academic cheating. A model of the role that the two traits may play in explaining academic cheating is presented.
