The Factor Structure and Reliability of a Six-Item Sense of Coherence Measure

The study investigated the factor structure and reliability of a six-item sense of coherence (SOC) measure. Participants were a South African white collar employee sample (n=7185) purposively selected from over 300 different companies across various business sectors. The sample constituted 34% male and 66% female and 34% Black, 18% Coloured, 11% Indian and 37% White employees. Exploratory factor analysis (EFA) was used for the structural analysis. The reliability of the scores was also estimated. A unidimensional structure seemed to best represent the six-item SOC measure. The internal reliability of the scores from the measure was high.     

Authentic leadership influences on organisational commitment in a South African state hospital

This study investigated the influence of authentic leadership (AL) on employee organisational commitment (OC) in a South African state hospital. A convenience sample of 222 employees (female = 81%; black = 82%) completed the Authentic Leadership Questionnaire on their perceptions of AL behaviours among their leaders; namely self-awareness, relational transparency, internalised moral perspective, and balanced processing. The employees also completed the Organisational Commitment Questionnaire to self-report on their own OC; namely affective, continuance, and normative commitment. Data were analysed utilising regression analysis to predict employees’ self-reported OC from perceived AL behaviours. Findings suggest AL scores to predict OC scores as well as the OC dimensions of continuance and normative commitment. AL scores did not predict affective commitment. Employees whose leaders apply AL may be able to retain employees through increased OC.     

Validation of the Life Role Salience Scale in a South African setting

This study aimed to validate the Life Role Salience Scale (LRSS) in a South African context. Respondents were 300 working adults (72.3% = women; 57.9% = non-white; mean age = 35.12 years, SD = 10.25 years; mostly from the finance sector = 35.6%). Confirmatory factor and exploratory factor analyses were conducted to determine the LRSS’s factor structure and reliability of scores from the scale for the South African sample. Results yielded five factors emerging from the analyses: Homecare role reward value and homecare role commitment; marital role reward value and marital role commitment; occupational role commitment; occupational role value reward; and parental role reward value. The reliability of scores from the LRSS ranged from 0.79 (parental role reward value) to 0.95 (homecare role reward value and homecare role commitment). The LRSS shows validity for research use in South Africa.     

Evaluating fit of the Prospective and Retrospective Memory Questionnaire (PRMQ) in a Nigerian adult population

This study aimed to evaluate the latent structure of the Prospective and Retrospective Memory Questionnaire (PRMQ) and to estimate the reliability and validity of scores from the measure in a Nigerian adult population (N = 758; age range = 18 - 63 years; females = 52.24%). Respondents also completed the Cognitive Failures Questionnaire (CFQ). The data were analysed utilising confirmatory factor analysis (CFA). The results suggest the PRMQ to have a tripartite structure characterised by the following features: general memory, plus eight prospective and eight retrospective memory items. Scores from the PRMQ had evidence of convergent validity with the CFQ. The reliability of scores from the PRMQ was of acceptable magnitude for the research purposes investigated in the study.     

Validation of the work engagement,job satisfaction,psychological empowerment,and organisational citizenship measures in a mining sector setting in Zimbabwe

This study aimed to validate measures of work engagement, job satisfaction, psychological empowerment, and organisational citizenship for use with employees in a mining enterprise in Zimbabwe. Miners (N = 176, males = 85.2%, females = 1.3%; age range = 24–65 years; general workers = 92%) completed the Utrecht Work Engagement Scale (UWES), the Psychological Empowerment Scale (PES), the Minnesota Job Satisfaction Questionnaire (MSQ20), and Organisational Citizenship Behaviour Checklist (OCB-C20). Findings, following exploratory factor analysis, suggest scores from the UWES, PES, MSQ20, and OCB20 to be reliable for research purposes in the Zimbabwean mining sector setting.     

Structure of the Experience of Work and Life Circumstances Questionnaire among South African employees in the financial services and health sectors

This study sought to validate the Experience of Work and Life Circumstances Questionnaire (WLQ) in South Africa. Respondents were 393 employees within the financial services (n = 238) and health sector (n = 155). Results from the exploratory factor analysis indicated the WLQ to be a unidimensional measure. The goodness-of-fit statistics following confirmatory factor analysis (CFA) indicated a well-fitting measurement model for the WLQ. The WLQ appears to yield reliable and valid scores for use in South African work settings.     

Examining the Psychometric Properties of the Utrecht Work Engagement Scale in Two Spanish Multi‐occupational Samples

The aim of this study was to provide some evidence of reliability and validity of the 15‐item Spanish version of the Utrecht Work Engagement Scale (UWES) between two multi‐occupational samples. In two different studies, 525 human services employees (study 1; males = 233; females = 292) and 409 multi‐occupational employees (study 2; males = 179; females = 230) completed the Spanish UWES. In study 1, our results revealed satisfactory levels of reliability for each subscale. In addition, the confirmatory factor analysis revealed that the three‐factor model fitted better than the one‐factor model and supported the theoretical three‐factor structure (vigor, dedication, and absorption). Furthermore, results from the multi‐sample analysis found strict factorial invariance of the Spanish UWES across gender, suggesting that the UWES factors show the same composition and interpretation in both groups. In study 2, our results once again confirmed the same three‐factor structure for the Spanish UWES. We found support for theoretically proposed two‐factor model including: (1) emotional exhaustion and depersonalization and (2) all three dimensions of engagement plus personal accomplishment. We also found evidence of convergent, discriminant, and incremental validity with respect to burnout, life satisfaction, and perceived stress. In short, our results provide empirical support for structural validity of the Spanish UWES in multi‐occupational workers.     

Psychometric, diurnal, and electrophysiological correlates of activation.

Several studies were performed using Thayer's Activation-Deactivation Adjective Check List (AD-ACL). Factor analysis of college students' scores identified a single activation factor representing a continuum ranging from sleep through wakefulness. Next, changes over the diurnal cycle in activation factor scores were demonstrated. One-week test-retest reliability was also investigated. Finally, activation scores were related to pulse rate, respiration rate, and skin resistance level under passive and active conditions. Correlations between factor scores and electrophysiological measures were higher than were intercorrelations of electrophysiological measures, indicating that scores on this revised activation factor represent a valid measure of phenomenological bodily activation level.

A psychometric evaluation of the Harvey Imposter Phenomenon Scale

In this article, we present psychometric properties on the 14-item Harvey Imposter Phenomenon (IP) Scale (Harvey, 1981) among a sample of U.S. adolescents (N = 136). Item analyses, internal consistency reliability, and principal components analysis (PCA) were computed to assess the reliability and factor structure of the IP scores. Although the internal consistency reliability (e.g., Cronbach's alpha) was reasonably acceptable (alpha =.70), the item analyses and subsequent PCA suggest concern for the content homogeneity and factor structure of composite scores obtained from the 14-item measure. The results of this study suggest that the indiscriminate use of the Harvey IP Scale is cautioned relative to the insufficient psychometric properties.     

The career adapt-abilities scale-Nigeria form: Psychometric properties and construct validity

This study examined the psychometric properties of Career Adapt-Ability Scale (CAAS) in Nigeria. The CAAS consists of four subscales, each with six items that measure concern, control, curiosity and confidence as psychosocial resources for coping with occupational tasks, work traumas and transitions. The participants in this study included bank (N=143) and hotel (N=128) employees. Internal consistency estimates for the subscale and total scores ranged from good to excellent. The factor structure was similar to that of the CAASInternational Form. While the result revealed that age was significantly related to confidence, gender and education had no significant relationships with the four dimensions of adaptability.     

Differences between general computer attitudes and perceived computer attributes: development and validation of a scale

The aim of this study was to develop a tool for measuring individuals' dispositions toward the use of computers in their work environment. The study reports the construction and validation of a general computer attitude and perceived computer attribute scale. Exploratory factor analytical evidence with a sample of 381 employees indicated a structure underpinned by two constructs, an attitudinal factor and a perceived computer attribute factor. The internal consistency estimates of reliability of scores were .81 for the attitudinal factor and .89 for the perceived computer attribute factor. Compared to the computer attitude subscale, scores on the perceived computer attribute subscale correlated higher with computer experience and professional computer use within the sample.     

Reliability and Validity of a Paper-and-Pencil Test Measuring Hemisphere Preference

The present studies examined the reliability and validity of the Preference Test (PT), a widely used self-report index of preferred hemisphere thinking styles. The PT consists of items that intend to tap left-hemisphere and right-hemisphere cognitions. In the first study (N=47), PT scores were found to have reasonable test–retest stability. In the second study (N=334), a factor analysis of PT scores showed that the PT has a two-factor solution that can best be interpreted in terms of putative left- and right-hemisphere items. In the third study (N=29), background EEG activity (F3, F4, P3 and P4) of subjects was recorded. PT scores were found to be related to EEG asymmetry patterns for frontal, but not for parietal, recording sites. More specifically, subjects with a left-hemisphere preference displayed relatively stronger left frontal activity than subjects with a right-hemisphere preference. By and large, the present findings provide strong support for the reliability and some suggestive evidence for the validity of the PT.     

组织信任对员工态度和离职意向、组织财务绩效的影响

为了探讨组织信任对个体和组织的作用,在全国不同地区43家企业进行了问卷调查,得到801份有效问卷。结果表明,在个体方面,多层线性模型（HLM：hierarchical linear modeling）分析的结果显示：组织信任对个体的工作满意度、情感承诺有显著的正向预测效果,对离职意向具有显著的负向预测效果;组织信任对工作满意度、情感承诺与离职意向之间的关系都具有显著的调节（加强）作用。在组织方面,结构方程模型的分析结果显示：组织信任通过组织学习和组织创新的完全中介作用于组织的主观财务绩效,即一方面分别通过组织学习和组织创新的完全中介作用于财务绩效,另一方面直接通过组织创新的完全中介作用于组织的财务绩效

Assessing the impact of stressful incidents in organizations: the development of an extended impact of events scale

Employers are becoming increasingly aware of the risks to employee wellbeing associated with the traumatic incidents that occur in the workplace. Despite this increased organizational awareness of the need to protect employees from the damaging effects of traumatic events, there has been little provision to help organizations to evaluate their management systems and post trauma interventions. This problem of a lack of evaluation has become more important as a growing body of evidence has provided evidence that suggests that trauma debriefing, the widely used approach to traumatic stress may be ineffective or damaging. The problem for an organization is to have a means of assessing the impact of a traumatic incident on exposed employees soon after the event and at regular intervals as a way of tracking the effectiveness of the treatment and rehabilitation programme. This paper examines the development and validation of a traumatic stress questionnaire designed to be used by trained practitioners working with traumatized employees. The extended impact of events scale (IES-E), took the 15 items from the impact of events scale (IES) and added eight new items which had been chosen on the basis of existing theory and clinical experience to represent the traumatic stress symptom of hyperarousal. Two studies are reported which examine the structure and reliability, and then the discriminant validity of the extended scale when used with a working population. The first study involved a factor analysis of the IES-E items using data collected from 105 subjects who had formally reported exposure to stressful work events to their employing organization. The second study then used the IES-E to compare employees self-reporting of the impact of either a major positive or a major negative life event. The results of the first study confirmed the presence of the re-experience and avoidance symptoms as a response to a traumatic event (as in the IES) but, in addition, identified a new factor, arousal and a new measurement model based on a single general factor. The reliability coefficients for all three scales and the general factor were found to be good. The second study showed that IES-E scores on re-experience, avoidance, arousal and the general factor could be used to discriminate between the subjects reporting major positive and negative life events. Two measurement models can therefore describe the impact of stressful events, the first based on three orthogonal factors, and the second based on a single general factor. The theoretical implications of these findings are explored.
