Research suggests there may be race, sex, and ability differences in score improvement on different selection tests and methods when retested (Schleicher, Van Iddekinge, Morgeson, & Campion, 2010). However, it is uncertain what individual differences moderate retest performance on GMA assessments, and why. In this study, 243 participants were retested on the Wonderlic Personnel Test (WPT). There was no evidence that race, sex, emotional stability, or conscientiousness moderate retest performance on the WPT, although SAT scores did positively predict retest performance. Individuals within the interquartile range of the initial WPT scores gained more when retested than those with more extreme scores. Establishing artificial cut-off levels demonstrated that those below the cut-off gained more when retested than those above the cut-off. Therefore, average-scorers and in some cases lower-scorers who may have failed to meet a predetermined cut-off are encouraged to re-test as they have little to lose and much to gain.

Industrial and organisational (I-O) psychology is a profession which entails a broad spectrum of working activities. One of these activities is workplace counselling which forms a significant part of the internship programme. However, interns often lack the necessary skills to provide counselling. In order to function in a counselling role, the I-O psychologist should have the necessary training to be equipped with counselling skills. It is evident from previous studies that I-O psychology practitioners often feel they lack the ability to counsel individuals sufficiently. Therefore it is important for I-O psychology students to focus on their development to become effective counsellors by focussing on their inter- and intrapersonal skills as part of the skills package as a counsellor. Personal Growth Initiative (PGI) is one way of measuring a person’s intrapersonal skills in terms of the individual’s intention to change and grow. The main aim of this study was to measure the prevalence of PGI among I-O psychology students. Participation in this study was limited to I-O psychology students (N = 568). The students differed in terms of gender, age, ethnicity, and language. The results provided the researcher with an indication of what the students’ intention to grow and develop as an individual entails in order to provide a basis for further research, namely to develop a training programme for I-O psychology students as workplace counsellors.. The PGI of the students were measured by means of the Personal Growth Initiative Scale (PGIS). This is a nine-item instrument with a six-point Likert type scale ranging from 0 (definitely disagree) to 6 (definitely agree). The results indicated that PGI is prevalent among the I-O psychology students. Furthermore, the study showed that PGI is relevant to all gender and ethnic groups amongst I-O psychology students. Significant differences were found for the different ages and languages. From the results it is recommended that higher education institutions adapt training programmes to foster personal growth initiative amongst I-O psychology students. Future research can also make use of the PGIS-II to measure PGI as this is the latest version of the construct. In terms of the organisation it is recommended that I-O practitioners should be more growth focussed. / MCom (Industrial Psychology), North-West University, Potchefstroom Campus, 2015

A considerable amount of academic attention has been directed towards the relationship between service quality and customer satisfaction. But the nature of the exact relationship is still shrouded with uncertainty. In addition, few researches focus on the dimensions of service quality and their differing impacts on customer satisfaction in western fast food restaurants. This paper examines whether or not quality and satisfaction should be considered as a single construct, or distinct, separable constructs. Customer satisfaction is typically evaluated by means of a single item scale and sometimes multiple item scales. Conversely, this empirical study adopts a different approach and considers customer satisfaction as a multi-dimensional construct just as service quality, but argues that customer satisfaction should be operationalized along the same corresponding items on which service quality is operationalized. The SERVQUAL instrument was slightly modified to measure the relationship between service quality and customer satisfaction among customers in western fast food chains in Kaohsiung. The research survey captures customers¡¦ perceptions of excellent service and compares it with their overall satisfaction. Using multiple regression analysis and T-test, the paper also reports on how socioeconomic and demographic disparities can influence the perception of service quality and satisfaction. Based on the research findings, the service quality and customer satisfaction are indeed independent but are closely related constructs. Their relationship suggests that an increase in one will lead to an increase in another. The statistical analysis also revealed that demographic variables can have major influences on service quality and customer satisfaction. The aim of the study is to supply useful results for future customer satisfaction researches in the fast food industry and provide insights into market segmentation strategies.

Tiden människan spenderar på sin arbetsplats är en stor del av ens liv, därför är det fundamentalt för välbefinnandet att undersöka vilka faktorer som är avgörande för att du ska trivas där. Denna studie ämnade undersöka demografiska skillnader, exempelvis stora och mindre åldersskillnader mellan anställd och närmsta chef, detta ställde vi i relation till anställdas attityd till ledarskap och andra trivselfaktorer. Datainsamlingen bygger på en enkätundersökning konturerad utifrån utvalda frågor från två tidigare, redan väl beprövade mätinstrument. Resultaten indikerar att det fanns ett signifikant samband mellan Tiden anställd och chef har arbetat tillsammans och attityd till ledarskap. Det fanns även signifikanta skillnader mellan personer som jobbade inom den privata kontra offentliga sektorn i relation till upplevt socialt stöd. / The amount of time people spend on their workplace is a big part of their life. Therefore, it should be essential for further increasing of the wellbeing, to investigate and determine which factors indicates jobsatisfaction. The aim of this study was to investigate demographic differences, for example big and minor age differences between the employee and their closest manager. This was put in relation to the employee’s attitude towards the experienced leadership and other factors determining jobsatisfaction. The collection of data is extracted through a survey, constructed with selected questions from two already validated measuring instruments. The result from this study indicates a significant relation between the amount of time the employee and closest manager have worked together and attitudes the employee has towards leadership. Furthermore, it yielded significant result in regard to differences between people that worked in the private or public sector, when put in relation to the experienced social support.

Doctor of Philosophy / Department of Human Nutrition / David A. Dzewaltowski / Consumption of fruits and vegetables (FV) contributes to healthy growth and development among youth. For effective intervention development, an understanding of the underlying casual influences on consumption is needed. The current dissertation is intended to identify whether influences on youth fruit and vegetable consumption (FVC) vary by age, gender, ethnicity and socioeconomic status (SES). The series of four chapters focus on self-efficacy for FVC and proxy efficacy to influence other adults to provide supportive FV environments. Chapter One reviews studies examining the influences on youth FVC. Consistently across studies, FV preferences and FV availability influenced youth FVC. Chapter Two and Chapter Three report studies documenting that children's confidence (proxy efficacy) to influence parents to make FV available and to influence other adults (after-school staff) to make FV available are independent but related constructs to self-efficacy to eat fruits and self-efficacy to eat vegetables. Differences were found in these constructs according to school demographic variables and youth demographic variables. Chapter Two reports that youth attending elementary schools with lower concentrations of racial/ethnic diversity and higher concentrations of high SES were more confident in influencing their parents to make FV available than youth attending schools with higher concentrations of racial/ethnic diversity and higher concentrations of low SES. Although analyses of cross sectional data collected on elementary-aged youth presented in Chapter 3 showed no demographic differences at the school level, Chapter Four examined longitudinal data across sixth-, seventh- and eighth-grade and found demographic differences using youth level variables. Across the middle school years, youth declined in proxy efficacy and racial/ethnic minority youth declined at a significantly faster rate than white youth. Each year, male and lower SES youth were significantly lower in proxy efficacy than females and higher SES youth, respectively. Thus, school or youth demographic differences in self-efficacy and proxy efficacy may contribute to the understanding of why males and lower SES youth eat less FV than females and higher SES youth.

Major changes that emphasise the importance of a balanced work and family life have occurred within organisations. Inability to manage this integration between the work and home domains can affect the performance of organisations and the wellbeing of their employees. In order to measure work-home interaction and wellbeing, it is important to use valid, equivalent and reliable instruments. However, there is a lack of empirical research when investigating work-home interaction, burnout and work engagement in the earthmoving equipment industry in South Africa. Furthermore, the earthmoving equipment industry is a multicultural environment and construct equivalence across subgroups therefore becomes important when measuring work-home interaction, burnout and work engagement across different cultural or language groups. It also seems relevant to consider differences in the work-home interaction and work wellness levels between important demographic groups in the earthmoving equipment industry. It appears as if burnout and engagement can be seen as part of the total wellness continuum; and that job characteristics may be related to burnout and engagement through negative and positive work-home interaction. However, little information was found that included these factors in a structural model for the earthmoving equipment industry. The objectives of this research were to test the psychometric properties of the Survey Work- Home Interaction - Nijmegen (SWING), the Maslach Burnout Inventory - General Survey (MBI-GS) and the Utrecht Work Engagement Scale (UWES); to determine if various demographic groups differ with regard to work-home interaction and wellbeing; and to test a structural model that includes job characteristics, work-home interaction and wellbeing for employees in the earthmoving industry. A cross-sectional survey design was used. Random samples (n = 528) were taken from employees in the earthmoving equipment industry in Gauteng, the Limpopo Province, Mpumalanga, the Northern Cape, the Western Cape, the Eastern Cape, Kwa-Zulu Natal and the North West Province. Structural equation modelling confirmed a four-factor model of work-home interaction which measures negative work-home interference, positive work-home interference, negative homework interference and positive home-work interference. This factor structure was equivalent across language, ethnicity, gender, education, marital status and parental status. All four factors were reliable. The participants reported more negative WHI than negative HWI, and more positive HWI than positive WHI. It was found that statistically significant differences that are based on age, gender, language, ethnicity, a partner's contribution to household income and the different business units exist between the demographic groups. The results confirmed a four-factor structure of burnout (exhaustion, cognitive weariness, cynicism and professional efficacy) and a two-factor structure of work engagement (including vigour and dedication). These structures were equivalent across language and education groups, and all scales were reliable. SEM analyses supported a two-factor structure for the wellness construct, consisting of burnout (exhaustion, cognitive weariness and cynicism) and engagement (vigour, dedication and professional efficacy), which was equivalent for the language and education groups. Statistically significant differences that are based on age, gender, language and the different business units were found between the demographic groups. Structural equation modelling showed that job demands are associated with negative WHI and consequently with burnout, providing support for a full-mediation effect of negative WHI. Job resources were associated with negative WHI and consequently with burnout, providing support for partial mediation of negative WHI between job resources and burnout. Job resources were also associated with positive WHI and consequently with engagement, providing support for partial mediation of positive WHI between job resources and engagement. Recommendations for the organisation and future research were made. / Thesis (Ph.D. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2007.
