An exploratory factor analysis on the measurement of psychological wellness

Gropp, Liezl 30 June 2006 (has links)
This research investigated the psychometric characteristics of self-actualisation, locus of control, sense of coherence and emotional intelligence as constructs of psychological wellness. Details of the intercorrelatedness of the various constructs will assist in understanding the nature of psychological wellness and its measurement. In the literature review a definition for psychological wellness was determined by studying various definitions and models of psychological wellness. During this investigation it was determined that the four constructs mentioned above were related to psychological wellness. An explorative factor analysis was conducted to address the empirical research questions. Three factors (psychological adjustment, self-actualisation and stress management) were extracted from the analysis. The descriptive statistics were analysed in terms of management responsibility, gender and race. The findings of the explorative factor analysis supported the theoretical definition of psychological wellness. It was found that self-actualisation played a key role in psychological wellness. Meaningfulness, although indicating a low loading on all three factors, must be present to provide meaning to day to day functioning. / Industrial and Organisational Psychology / MCOM (Industrial and Organisational Psychology)

The Effects of Social Capital and Open Innovation on R&D Outcomes and Job Satisfaction : A Study of The Indian Deference Sector

Patel, Mitra Kumar January 2017 (has links) (PDF)
Social Capital and Open Innovation are important for organisational growth, as both of them influence Innovation, Learning and Job Satisfaction. The literature indicates that informal network measured as social capital and formal network measured as open innovation influences positively to organizational innovation performance, learning and job satisfaction. Most of the studies in this area have been carried out using univariate approaches, and only few dimensions of both Social Capital and Open Innovation have been considered. Current literature outlines the positive influence of Social Capital and Open Innovation on Learning, Innovation and Job Satisfaction. In this study, an attempt has been made to develop a multi-dimensional framework for Social Capital and Open Innovation, in order to better understand the nuances of Learning, Innovation and Job Satisfaction in an R&D setting. Another important factor influencing the R&D outcomes is Absorptive Capacity; it is the capacity of the organisation to identify and use external knowledge. The direct and moderating role of Absorptive Capacity has been examined. Both theoretical and conceptual models have been proposed, and a measurement scale in form of a questionnaire has been developed. Data was collected from 35 organisations across India operating in the field of defence R&D. The sample included Government-run R&D organisations, Public Sector Units (PSUs) and private firms, and total of 331 engineers/scientists responded to the survey. Data was analysed using statistical methods such as Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), Common Method Variance (CMV), and Analysis of Variance (ANOVA). Reliability and validity of the proposed scales for the constructs have been verified using appropriate techniques, and further inferences have been drawn by using regression techniques and Structural Equation Modeling (SEM) to assess the proposed relationships. It has been found that both Social Capital and Open Innovation have positive influence on Learning, Innovation and Job Satisfaction. Further, it was found that Absorptive Capacity had a positive association with both Innovation and Learning. However, Absorptive Capacity did not moderate the relationship of Social Capital with both Innovation and Learning, but was found to moderate the relationship between Open Innovation and Innovation, for both outbound and inbound approaches of Open Innovation. Bonding Social Capital had a relatively stronger positive association with Learning, while Bridging Social Capital was found to have a stronger relationship with Innovation. In summary, networking factors Social Capital and Open Innovation have strong positive association with R&D outcomes measured as innovation performance, learning and job satisfaction.

Factorial invariance of an employee engagement instrument across different race groups

Gallant, Wesley Herschelle 11 1900 (has links)
The overall objective of this study was to determine the factorial invariance of a South African-developed Employee Engagement Instrument (EEI) across different race groups in financial institutions. A secondary objective of this study was to determine whether race groups differ significantly with regard to the six dimensions of the employee engagement instrument. A quantitative, cross-sectional and descriptive research design was followed in this study, using a non-probability, convenience sampling (N = 1175). The EEI was electronically administered to 285 000 businesspeople from various demographic backgrounds, which form part of a research database. The focus was respondents from financial institutions. Descriptive and inferential statistical analysis was employed to achieve the empirical objectives of this study. Findings from the statistical analysis indicated that White and Black employees differed significantly with regards to how they are engaged by their immediate managers; however, the practical significance was small. Furthermore, the employee engagement instrument was found to be reliable and valid and the instrument was invariant across the four different race groups. By understanding how employees from different backgrounds are engaged it enables organisations to customise their engagement programmes to meet the needs of the various types of employees within the organisation, instead of applying a “one size fits all” approach to engagement programmes. The findings of this study provided valuable insights into the importance of employee engagement in a South African context, especially for financial institutions. Finally, the study adds to the vast body of knowledge that exists with regard to employee engagement and race, both locally and internationally. / Industrial and Organisational Psychology / M. Com.

Structural equation modelling

Mohanlal, Pramod 06 1900 (has links)
Over the past two decades there has been an upsurge in interest in structural equation modelling (SEM). Applications abound in the social sciences and econometrics, but the use of this multivariate technique is not so common in public health research. This dissertation discusses the methodology, the criticisms and practical problems of SEM. We examine actual applications of SEM in public health research. Comparisons are made between multiple regression and SEM and between factor analysis and SEM. A complex model investigating the utilization of antenatal care services (ANC) by migrant women in Belgium is analysed using SEM. The dissertation concludes with a discussion of the results found and on the use of SEM in public health research. Structural equation modelling is recommended as a tool for public health researchers with a warning against using the technique too casually. / Mathematical Sciences / M. Sc. (Statistics)

Método: Participaram deste estudo pacientes do sexo feminino com relato de dor cervical há mais de 3 meses durante o movimento ou repouso A amostra foi composta por 30 indivíduos (33,43±10,32 anos) para a etapa de teste da versão pré-final, 100 indivíduos (38,89±10,84 anos) para a confiabilidade e 180 indivíduos (37,49±11,86 anos) para a validadade de construto, para a análise da consistência interna e validade estrutural. O processo de tradução e retrotradução ocorreu em 5 etapas: 1) Tradução inicial para o português, 2) Síntese de traduções, 3) Retrotradução, 4) Comitê de especialistas, e 5) O teste da versão pré-final. Para validade de construto a pontuação do ProFitMap-neck foi correlacionada com a pontuação do Neck Disability Index (NDI), além disso, foram utilizados para fins de correlação a Escala de Ansiedade e Depressão Hospitalar (HADS-A e HADS-D), a Escala Tampa de Cinesiofobia e o Short Form - 36 (SF-36). Para a análise fatorial exploratória foi utilizada a Análise de Componentes Principais, o indice de Kaiser-Meyer-Olkin (KMO) e % de variância cumulativa. Para a análise da consistência interna foi utilizado o coeficiente de ? de Cronbach. Para a confiabilidade foi utilizando o Coeficiente de Correlação Intraclasse (CCI). O coeficiente de correlação de Pearson foi utilizado para verificação das correlações. A magnitude da correlação foi graduada da seguinte maneira: R<0,29: pobre; 0,3<R<0,69: moderada; R>0,7: forte. Resultados: Durante o processo de teste da versão pré-final não foram relatadas dúvidas pela amostra de pacientes ao responder o instrumento. Para a escala de Sintomas/Intensidade do ProFitMap-neck versão português brasileiro foram verificados dois domínios (Escala de Sintomas/Intensidade Geral e Escala de Sintomas/Intensidade Equilíbrio) com porcentagem de variância cumulativa de 57,33% e índice KMO=0,66. Para a escala de Sintomas/Frequência do ProFitMap-neck foi verificado apenas 1 domínio com porcentagem de variância cumulativa de 56,20% e KMO=0,84. Para a escala de Limitação Funcional do ProFitMap-neck foram verificados 2 domínios (Postura e AVDs e Movimento e Percepção de Saúde) com porcentagem de variância cumulativa de 56,28% e KMO=0,57. Todos os itens apresentaram carga fatorial superior a 0,2. A análise de consistência interna demonstrou valores de alpha de cronbach adequados (alpha>0.70) para todos os domínios do ProFitMap-neck. Na reprodutibilidade foram verificados valores de CCI excelentes para todos os domínios e escalas (ICC>0,75). Nossos achados demonstraram correlações moderadas/fortes e negativas entre a pontuação total do NDI e as pontuações dos domínios e escalas Sintomas/Intensidade, Sintomas/Frequencia e Limitação Funcional do ProFitMapneck (R=-0,65, R=-0,56 e R=-0,71, respectivamente). Foram verificadas correlações no geral moderadas/fortes e positivas entre os escores das ferramentas SF-36 e ProFitMap-neck. Para as correlações entre Ansiedade, Despressão e Cinesiofobia e as Escalas do ProFitMap-neck versão português brasileiro foram verificadas correlações em sua maioria moderadas e fortes (-0,32<R<-0,82). Conclusão: O ProFitMap-neck versão português-Brasil apresentou índices psicométricos adequados e, dessa forma, está disponível para ser empregado na prática clínica e pesquisa em pacientes com dor cervical crônica. / Objective: This study aimed to perform the cultural adaptation and verify the reliability, internal consistency, structural validity and construct validity of the Profile Fitness Mapping neck questionnaire (ProFiMap-neck) in individuals reporting chronic neck pain. Method: This study recruited female patients with neck pain for more than three months during motion or at rest The sample consisted of 30 individuals (33.43 ± 10.32 years) to test the pre-final version, 100 individuals (38.89 ± 10.84 years) for reliability and 180 individuals (37.49 ± 11.86 years) for construct validity, analysis of internal consistency and structural validity. The process of translation and back translation occurred in 5 steps: 1) Initial translation into Portuguese, 2) Summary of translations, 3) Back-translation, 4) Committee of Experts, and 5) The test of the pre-final version. Construct validity was verified correlating scores on ProFitMap-neck and Neck Disability Index (NDI), Hospital Anxiety Depression Scale (HADS-A and HADS-D), Tampa Scale of Kinesiophobia and the Short Form - 36 (SF-36). Exploratory factor analysis was perfomed considering Principal Component Analysis, the Kaiser-Meyer-Olkin index (KMO) and percentange of cumulative variance. For the analysis of internal consistenc, we used ? Cronbach and for reliability Intraclass Correlation Coefficient (ICC) was used. The Pearson correlation coefficient was used to investigate correlations and the strength was graded as follows: R <0.29: poor; 0.3 <R <0.69: moderate; R> 0.7: Strong. Results: During the test of the pre-final version, volunteers did no report doubts. Structural validity retained two domains for Symptoms/Intensity ProFitMap-neck Brazilian Portuguese version (General Symptoms Intensity and Symptoms Intensity/ Balance) with cumulative percentage of variance of 57.33% and KMO=0.66. For the Scale Symptoms/Frequency of ProFitMap-neck we identified one domain, with cumulative percentage of variance of 56.20% and KMO = 0.84. For Functional Limitation of the ProFitMap-neck, we identified two domains (Posture and Movement and Diary Life Activities and Health Perception) with cumulative percentage of variance of 56.28% and KMO = 0.57. All items had factors loadings greater than 0.2. The internal consistency analysis revealed adequate alpha Cronbach values (alpha>0.70) for all ProFitMap-neck domains. We obtained excellent ICC values for all domains and scales (ICC> 0.75). Our findings showed moderate/strong and negative correlations between the total score of the NDI and the scores of the domains and scales Symptoms/Intensity, Symptoms/Frequency and Functional Limitation of ProFitMap-neck brazilian portuguese version (R = -0.65, R = -0.56 and R = -0.71, respectively). Correlations between the scores of the SF-36 and ProFitMapneck tools were in the majority moderate/strong and positive. For correlations between anxiety, depression and kinesiophobia and the scales of the ProFitMap-neck brazilian portuguese version were observaded moderate and strong values (-0.32 <R <-0.82). Conclusion: ProFitMap-neck portuguese-Brazil version showed adequate psychometric indexes and, therefore, it\'s available to be apllied in clinical practice and research in patients with chronic neck pain.

Entrepreneurial orientation and its impact on innovation intensity in the Omani corporate sector

Arshi, Tahseen Anwer January 2016 (has links)
Entrepreneurial Orientation (EO) is a widely researched construct of corporate entrepreneurship. Despite long-standing research on EO, past studies on this construct have been unable to resolve issues related to its measurement. Innovation Intensity (II) is also a dynamic construct of corporate entrepreneurship but has received relatively less empirical attention. Previous research has reported an absence of an empirically validated quantitative scale of innovation, particularly innovation intensity. This research has addressed these gaps by proposing a refinement and validation of the Entrepreneurial Orientation scale and the development of an Innovation Intensity scale. The research proposes an Entrepreneurial Transformational Model (ETM) positing that EO impacts II. A predominantly quantitative research strategy supported by qualitative inputs, is employed to obtain empirical data from 404 corporate firms in Oman, drawing from a list of corporate firms registered with the Oman Chamber of Commerce and Industry. A mix of questionnaire survey and semi-structured interviews was conducted with senior managers from firms representing various industries of the Omani corporate sector. Utilising exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and structural equation modelling (SEM), a two-stage data analysis approach was adopted. Measurement and structural models were developed for EO and II measures, while a complete SEM model was developed to test the causal relationship between EO and II. The results indicate that EO is a second-order construct consisting of five first-order factors, namely ready to innovate, competitive aggressiveness, autonomy, risk taking and proactiveness, which are its reflective components. Similarly, II is a second-order construct consisting of two first-order factors, namely degree and frequency of incremental and radical innovation, which are its reflective components. The II scale developed through this study allows corporate firms to assess their innovation intensity on a two-dimensional four-celled grid with varying levels of degree and frequency of innovation. Finally, EO is found to influence II and the entire relationship is posited as Entrepreneurial Transformation Model. This study, by addressing the empirical irregularities, has brought clarity to the measurement of EO and II constructs and is an original contribution to the advancement of theoretical knowledge and improvement in professional practice.

Validation du Questionnaire d’ouverture au monde version 12-18 mois

Boucheneb, Hafida 07 1900 (has links)
Cette étude a pour objectif la validation d’un nouvel instrument qui intègre des concepts récents reflétant l’évolution de la paternité. Le Questionnaire d’Ouverture au Monde version 12 à 18 mois (QOMt) s’intéresse plus particulièrement aux comportements parentaux favorisant l’ouverture au monde chez l’enfant, fonction plus souvent attribuée au père (Le Camus, 2000). Le QOMt s’insère ainsi dans le débat sur la complémentarité des comportements parentaux en proposant des structures factorielles distinctes pour un échantillon de 664 pères et 225 mères. Six facteurs ont été extraits de l’analyse factorielle des mères (stimulation à la prise de risque, stimulation à la persévérance, protection, fixation de limites, réaction de l’enfant à la fixation de limites et discipline) dont trois ont une cohérence interne acceptable (alphas de Cronbach entre 0,44 et 0,80). Six facteurs ont émergé de l’analyse des pères (stimulation au dépassement de soi, à l’exploration, à l’autonomie et à la persévérance, fixation de limites et discipline) avec une cohérence interne acceptable (alphas entre 0,61 et 0,85). Parallèlement au QOMt, les familles ont participé aux procédures de la situation risquée et de la situation étrangère dans le but de tester la validité convergente et divergente. Cependant, seule la validité divergente est jugée satisfaisante. La fidélité, examinée avec la version préscolaire du Questionnaire d’Ouverture au Monde (QOM), suggère une stabilité des comportements parentaux de stimulation à la persévérance et des comportements maternels de stimulation à la prise de risque à travers le temps. En somme, bien que le QOMt ne soit pas un outil valide, il est intéressant de souligner que la stimulation à la prise de risque a uniquement émergé de l’analyse factorielle des mères, faisant ainsi contraste aux prémisses théoriques qui ont guidé notre étude. Nos résultats doivent cependant être interprétés avec prudence puisqu’une analyse confirmatoire s’avère nécessaire. / This study investigates the validity of a novel instrument built around recent concepts that exhibit the evolution of paternity. The Toddler Openness to the World Questionnaire (QOMt in french) focuses more specifically on parental behaviors that favor openness to the world in children, a function mostly attributed to fathers (Le Camus, 2000). Therefore, the QOMt joins the debate on the complementarity of parental behaviors by proposing two distinctive factorial structures for a sample of 664 fathers and 225 mothers. Six factors emerged from the mother’s factor analysis (stimulation of perseverance, stimulation of risk-taking, protection, limit setting, children’s reaction to limit setting and discipline) of which three have acceptable internal consistency (Cronbach alphas ranging from .44 to .80). Six factors emerged from the father’s analysis (stimulation of self-transcendence, stimulation of exploration, stimulation of autonomy, stimulation of perseverance, limit setting and discipline) with an overall acceptable internal consistency (Cronbach alphas coefficients ranging from .61 to .85).Along with the QOMt, families were asked to participate to the risky situation procedure and the strange situation procedure to test convergent and divergent validity. However, only divergent validity is considered to be satisfactory. Fidelity assessed using the preschool version of The Openness to the World Questionnaire (QOM in french) suggests that parental behaviors of stimulation of perseverance and maternal behaviors of stimulation of risk-taking are stable across time. In summary, while the QOMt isn’t a valid instrument, it is noteworthy to emphasize that stimulation of risk-taking only emerged from the mother’s factor analysis, therefore challenging our theorical framework. Our results should however be interpreted with caution as a confirmatory analysis is needed.
