Reliability of the Denison Organisational Culture Survey (DOCS) for use in a financial institution in South Africa

Franck, Chrisstoffel Jacobus 30 June 2005 (has links)
A survey of literature has revealed that there is a need for a reliability study of the Denison Organisational Culture Survey (DOCS) for use in a financial institution in South Africa. The major objective of this research was therefore to determine the internal consistency reliability of the DOCS - in other words, to determine the accuracy or consistency with which the set of survey items measures one particular scale. The total sample of 2 735 individuals used in this research consisted of both male and female full-time employees of a financial institution in South Africa. The results of this introductory study on the reliability of the DOCS in South Africa demonstrated clear support for similar research conducted abroad and proved to be compatible with the cognitive-behaviouristic psychology movement's original concept of organisational culture. The reliability of the DOCS, as applicable to this South African sample, reflects statistical significant internal consistency. / Industrial and Organisational Psychology / M. Comm.

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.

Development of selected sulphur compounds and oxygenated volatile organic compounds reference gas mixtures for air quality monitoring

Leshabane, Nompumelelo 05 1900 (has links)
Highly accurate analysis for the quantification of sulphur compounds and oxygenated volatile organic compounds are crucial for the adherence of the legislation in different environmental sectors. The sulphur compounds and oxygenated volatile organic compounds measurements are challenging, due to various factors such as molecules being adsorbed on the inner surfaces of cylinders. It is therefore important to produce accurate and reliable reference gas mixtures with mole fraction at ambient levels for the air quality monitoring and field of gas sensing in South Africa. The challenges in producing sulphur compounds and oxygenated volatile organic compounds reference gas mixtures are that the overall process from gravimetric preparation steps until the comparison analysis process and the stability of mixture in the gas cylinder, results in the large measurement uncertainties. In order to produce reference gas mixtures of the highest level, three important steps are followed: purity assessment of starting material, gravimetric preparation, and verification/validation of prepared gas mixtures. The purity analysis of high purity starting materials was determined using gas chromatography coupled with various detectors and Karl Fischer for determination of moisture content in high purity chemicals. The sulphur compounds and oxygenated volatile organic compounds to be developed in this study were hydrogen sulphide, sulphur dioxide, acetone, methanol, ethanol, isopropanol, and n-butanol. These components were produced following the International Organisation for Standardisation documents at mole fraction of 10 µmol/mol for sulphur compounds and 5 µmol/mol for oxygenated volatile organic compounds. The preparation of sulphur compounds reference gas mixtures was done with a static gravimetric method using a direct method where a target component was transferred directly into the cylinder. The preparation of oxygenated volatile organic compounds used an indirect method whereby a target liquid component from high purity chemicals was transferred into a cylinder using a gas-tight syringe.The comparison between the reference gas mixtures was validated using Non-Dispersive Ultra-Violet analysers (NDUV), gas chromatograph coupled with pulsed discharge helium ionisation detector (GC-PDHID, UV fluorescence analysers for sulphur compounds and gas chromatograph coupled with flame ionisation detector (GC-FID) for the oxygenated volatile organic compounds. A multi-point calibration method was used to analyse sulphur dioxide and hydrogen sulphide on the NDUV analyser, and the single-point calibration method was used for analysis on the gas chromatography and UV fluorescence where a sample mixture is analysed against a reference mixture with a similar mole fraction. The statistical data considered during analysis included calculation of the instrument drift and percentage relative standard deviation to check measurements repeatability, reliability, and measurement uncertainty. The gravimetric results of prepared sulphur compounds at 10 µmol/mol gave a percentage relative expanded uncertainty of 0.041 % REU for hydrogen sulphide, 0.12 % REU for sulphur dioxide. The gravimetric results of prepared oxygenated volatile organic compounds at 5 µmol/mol showed a percentage relative expanded uncertainty 0.068 to 0.35 % REU for isopropanol and ethanol respectively and less than 2.4 % REU for multi component of oxygenated volatile organic compounds. Finally, the primary standard gas mixtures of sulphur compounds and oxygenated volatile organic compounds were developed with the highest metrological measurement uncertainty level of (k=2). / Environmental Sciences / M.

Reliability of the COntext Assessment for Community Health (COACH) tool when administered on mobile phones versus pen-paper: A comparative study among healthcare staff in Nairobi, Kenya.

Cederqvist, Melissa January 2015 (has links)
Aim: To investigate the reliability of the COntext Assessment for Community Health (COACH) tool on mobile phone versus pen-paper in Nairobi, Kenya. Background: One of the barriers to the progress of the MDGs has been the failure of health systems in many LMICs to effectively implement evidence-based interventions As a result of the “know-do” gap, patients do not benefit from advances in healthcare and are exposed to unnecessary risks. Better mapping of context improves implementation by allowing tailoring of strategies and interpretation of knowledge translation. COACH investigates healthcare contexts for LMICs and has only been used on pen-paper. With 5 billion mobile phone users globally, mobile technologies is being recognized as able to play a formal role in health services. Methods: Comparative study with 140 nurses/midwives and doctors in four hospitals in Nairobi. 70 were randomly assigned to mobile phone and pen-paper each. The tool was administered twice with a two week interval and test-retest reliability, internal consistency and interrater reliability were assessed. Findings: Excellent test-retest reliability for both pen-paper and mobile phone (ICC &gt;0.81). 45% (pen-paper) and 34% (mobile phone) moderate agreement between individual questions in round 1 and 2. Acceptable average Cronbach’s alpha (&gt;0.70). Conclusion: Both mobile phone and pen-paper were reliable and feasible for data collection. The findings are a good first step towards using COACH in Kenya. Additional research is needed for individual settings. Using mobile phones could increase healthcare facilities’ accessibility in implementation research, helping to close the “know-do” gap and reach the SDGs.
