Selection of industrial and organisational psychology master's students: exploring the validity of applied psychometric measures

Olivier, Karina Cornelia 10 1900 (has links)
The objective of this study was to investigate how well the academic performance of the Industrial and Organisational Psychology master’s students at a research institution can be predicted through psychometric measures. A non-experimental design was used in this empirical study. The sample consisted of one hundred and thirty-three IO Psychology master’s students over a five-year period. The secondary data for this research originated from the students completing the Graduate Verify Ability tests as well as the Occupational Personality Questionnaire, which are psychometric measures that form part of the selection. Both psychometric measures load onto the Person Job Match competencies. A theoretical relationship could be found between the Ability tests and academic success as well as the PJM competencies that included weighted scores from both psychometric measures. The empirical relationships, therefore, proved that the ability tests have the strongest predictive ability for academic success. / Industrial and Organisational Psychology / M. Com.

Gregory Research Beliefs Scale: Factor Structure and Psychometric Properties

Gregory, Virgil L., Jr 23 June 2009 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / GREGORY RESEARCH BELIEFS SCALE: FACTOR STRUCTURE AND PSYCHOMETRIC PROPERTIES The study at hand involves developing the Gregory Research Beliefs Scale (GRBS) to reliably and validly measure social work students’ beliefs about the function of research in social work practice. Research has considerable actual and potential benefits for practice. Social work students’ beliefs about this construct are vital. A description of the advantages of using research to inform practice is given. Additionally, the Council on Social Work Education and National Association of Social Workers’ policies that mandate the merger of research and practice are also provided to further justify the need for adequate psychometric evaluation of the construct. Details of the literature search strategy are described and critical evaluations of the empirical articles are conducted. Based on critical evaluations of instruments which have previously measured the same construct, a number of psychometric shortcomings are outlined to validate the need for further scale development of the construct. The present study’s objectives were to develop a scale which has an empirically and theoretically supported factor structure, acceptable coefficient alpha levels, empirically supported discriminant (divergent) validity, concurrent criterion validity, and known–groups criterion validity. Steps for developing the GRBS’s items, response format, sample, research design, and statistical tests are specified and conducted to determine the factor structure and psychometric properties. Finally, the strengths, limitations, and areas for future research are discussed.

New graduate nurse transition into practice : psychometric testing of Sims Factor H Assessment Scale

Sims, Caroline E. 29 January 2014 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Factor H is a newly identified phenomenon which describes a constellation of attributes of the new graduate nurse reflecting personality traits, intellectual abilities, and clinical judgment. In a previous pilot study conducted by this researcher nurse managers and experienced Registered Nurse (RN) preceptors described characteristics demonstrated by new graduate nurses demonstrating Factor H and the new graduate nurse’s ability to transition quickly and successfully into the RN role in the acute care environment. There is currently no instrument available to measure this phenomenon. The specific aim of this research was to develop and psychometrically test a scale designed to identify the presence of attributes of Factor H in the new graduate nurse. The Sims Factor H Assessment Scale (SFHAS) was developed and piloted with a sample of one hundred one new graduate nurses within three months of completing the their nursing program at one of three nursing schools in central and south central Indiana. Evidence of content validity was demonstrated through the use of the Content Validity Index conducted with a panel of four experts. Evidence of face validity was demonstrated through interviews with a group of new graduate nurses, nurse managers, and experienced RN preceptors. Principle Axis Factoring with Varimax rotation was used to demonstrate evidence of construct validity and the scale was found to have a single component which was identified as nursing personality. Evidence of criterion-related validity was demonstrated utilizing analysis of the SFHAS and the criterion scale for personality traits (NEO-FFI). Evidence of internal consistency reliability was demonstrated through analysis of inter-item correlations, Cronbach’s coefficient correlations, and item-total correlations. Test re-test reliability using interclass correlation was also conducted to demonstrate stability of the scale. The SFHAS was found to be reflective of nursing personality and not general mental ability or clinical judgment. Use of the SFHAS will allow organizations to evaluate the nursing personality of the new graduate nurse for fit into the work environment. Further study is recommended to gain clarity around the attributes which support successful transition of the new graduate nurse into practice in the acute care environment, also known as Factor H.

Smart Characters: Psychometrics and the Twentieth-Century Novel

Michalowicz, Naomi January 2023 (has links)
This dissertation examines how the trait of intelligence is portrayed in novels of twentieth-century Britain, and how this portrayal grapples with the quantitative revolution in the conception of intelligence, brought on by the invention of IQ testing in the 1900s. I trace the construction of characters’ intelligence across different genres, starting with Arthur Conan Doyle’s Sherlock Holmes stories, through the modernist Bildungsromane of Henry James, James Joyce, and Virginia Woolf, to Iris Murdoch’s realism, and finally to Lee Child’s late twentieth- century serial thrillers featuring Jack Reacher. I posit that the IQ model of intelligence as abstracted, quantified, and statistically measurable is profoundly at odds with the novelistic investment in the unique individual subject. This project traces the narratological strategies of characterization through which intelligence—or cleverness, or smartness, or brightness—are conveyed to the reader. Novels, generally speaking, do not provide the IQ scores of their characters; and though we might occasionally encounter an explicit narratorial characterization of some fictional being or other as “remarkably clever,” most often we must rely on perceptions of behavior, speech, and thought in order to assess characters’ intelligence, much as we do in real life. As the psychometric paradigm gained prominence in the psychological circles in the United States, England, and Europe, and as more people were exposed—and subjected—to intelligence testing, its values and assumptions gained more cultural traction. Attributes like mathematical facility, logical and systemic thinking, or a large vocabulary, are likely to yield a high score on an IQ test, as well as a favorable judgment in an informal, casual assessment, such as that of a date or a new acquaintance at a party. This dissertation, therefore, explores how this permeation of the psychometric paradigm into general culture affect the novelistic construction of smartness. Ultimately, I argue that against the IQ model, the novels I am reading construct a conception of intelligence as a coherent set of cognitive abilities, remarkably consistent across genres, which overlaps, yet reconfigures, the priorities and epistemological frameworks of psychometrics. This model centers on the notion of observation, i.e., a mix of sensory susceptibility to impressions and the cognitive skill of taking notice of the world and of other people. It is both anchored to the body by connoting a sensory experience, and divorced from it in conveying a more purely cognitive process, one of directing attention and processing information, thus renegotiating psychometric assumptions regarding embodiment and sensory experience—as well as the relationship between the individual’s intelligence, the world, and the minds of others.

HELP SEEKING EXPERIENCES OF ASIAN AMERICAN CAREGIVERS OF CHILDREN WITH AUTISM: A QUALITATIVE STUDY

Amani Khalil (18136753) 11 March 2024 (has links)
<p dir="ltr">This dissertation is a two-study dissertation divided into two chapters focused broadly on the help-seeking experiences of racial-ethnic minority caregivers of children with autism spectrum disorder (ASD). In chapter one, a systematic literature review was conducted to identify articles that have studied barriers in help-seeking for racial-ethnic minority caregivers of children with autism. A broad literature search across four databases was conducted (i.e., PubMed, PsycINFO, Education Resources Information Center, and Child Development and Adolescent Studies). The coding team identified 17 articles on help-seeking barriers for racial-ethnic minority caregivers of children with autism. A thematic analysis was then used to synthesize the help-seeking barriers identified across these 17 studies. Four themes emerged from our findings: logistical barriers, provider competence, ASD literacy, and cultural stigma. We also provided clinical recommendations for healthcare providers working with families with racial-ethnic minority caregivers of children with autism.</p><p dir="ltr">The second chapter was informed by the results found in chapter one. In chapter one, we found little research on Asian American caregiver perspectives on help-seeking barriers to autism services. Using caregiver perspectives, this research study sought to understand the help-seeking experiences of Asian American families. In this study, we conducted semi-structured qualitative interviews with 10 Asian American caregivers with a child aged 3-17 diagnosed with ASD. Interviews were conducted virtually, audio recorded, transcribed, and coded by three researchers. Data was analyzed using thematic analysis (Braun & Clarke, 2006). Our results indicated four themes in perceived barriers by Asian American caregivers of children with autism interviewees. Themes included: (1) logistical barriers, (2) provider level barriers competence, (3) ASD literacy, and (4) cultural stigma. We deliver clinical recommendations for providers to address the four barriers found in our study when working with Asian American families of children with ASD.</p>

The Rivermead Mobility Index allows valid comparisons between subgroups of patients undergoing rehabilitation after stroke who differ with respect to age, sex, or side of lesion

Roorda, L.D., Green, J.R., Houwink, A., Bagley, Pamela J., Smith, J., Molenaar, I.W., Geurts, A.C. January 2012 (has links)
To investigate differential item functioning or item bias of the Rivermead Mobility Index (RMI) and its impact on the drawing of valid comparisons with the RMI between subgroups of patients after stroke who differ with respect to age, sex, or side of lesion. DESIGN: Cross-sectional study. SETTING: A rehabilitation center in the Netherlands and 2 stroke rehabilitation units and the wider community in the United Kingdom. PARTICIPANTS: The RMI was completed for patients undergoing rehabilitation after stroke (N=620; mean age +/- SD, 69.2+/-12.5y; 297 [48%] men; 269 [43%] right hemisphere lesion, and 304 [49%] left hemisphere lesion). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Mokken scale analysis was used to investigate differential item functioning of the RMI between subgroups of patients who differed with respect to age (young vs older), sex (men vs women), and side of stroke lesion (right vs left hemisphere). RESULTS: No differential item functioning was found for any of the comparison subgroups. CONCLUSIONS: The RMI allows valid comparisons to be made between subgroups of patients undergoing rehabilitation after stroke who differ with respect to age, sex, or side of lesion.

Item hierarchy-based analysis of the Rivermead Mobility Index resulted in improved interpretation and enabled faster scoring in patients undergoing rehabilitation after stroke

Roorda, L.D., Green, J.R., Houwink, A., Bagley, Pamela J., Smith, J., Molenaar, I.W., Geurts, A.C. January 2012 (has links)
To enable improved interpretation of the total score and faster scoring of the Rivermead Mobility Index (RMI) by studying item ordering or hierarchy and formulating start-and-stop rules in patients after stroke. DESIGN: Cohort study. SETTING: Rehabilitation center in the Netherlands; stroke rehabilitation units and the community in the United Kingdom. PARTICIPANTS: Item hierarchy of the RMI was studied in an initial group of patients (n=620; mean age +/- SD, 69.2+/-12.5y; 297 [48%] men; 304 [49%] left hemisphere lesion, and 269 [43%] right hemisphere lesion), and the adequacy of the item hierarchy-based start-and-stop rules was checked in a second group of patients (n=237; mean age +/- SD, 60.0+/-11.3y; 139 [59%] men; 103 [44%] left hemisphere lesion, and 93 [39%] right hemisphere lesion) undergoing rehabilitation after stroke. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Mokken scale analysis was used to investigate the fit of the double monotonicity model, indicating hierarchical item ordering. The percentages of patients with a difference between the RMI total score and the scores based on the start-and-stop rules were calculated to check the adequacy of these rules. RESULTS: The RMI had good fit of the double monotonicity model (coefficient H(T)=.87). The interpretation of the total score improved. Item hierarchy-based start-and-stop rules were formulated. The percentages of patients with a difference between the RMI total score and the score based on the recommended start-and-stop rules were 3% and 5%, respectively. Ten of the original 15 items had to be scored after applying the start-and-stop rules. CONCLUSIONS: Item hierarchy was established, enabling improved interpretation and faster scoring of the RMI.

Validação da versão em português da entrevista telefônica para avaliação do estado cognitivo - modificada (TICS-M) em pacientes acometidos por acidente vascular cerebral / Validation of the portuguese version of the telephone interview for cognitive status - modified (tics-m) among post-stroke patients

Baccaro, Alessandra Fernandes 04 June 2014 (has links)
Introdução: O AVC (acidente vascular cerebral) é uma das mais importantes causas de alterações neuropsicológicas. Uma avaliação cognitiva inicial realizada por telefone implicaria em um diagnóstico mais precoce de prejuízo cognitivo e demência, reduzindo custos e tempo. Objetivo: Examinar as propriedades psicométricas da versão brasileira da Entrevista Telefônica para Avaliação do Estado Cognitivo - Modificada (TICS-M) em pacientes pós-AVC. Métodos: Previamente à validação da TICS-M em indivíduos acometidos por AVC, foi realizada tradução para o Português do Brasil e adaptação transcultural da versão original da TICS-M em uma amostra de 30 sujeitos não clínicos. Após esta fase, um subgrupo de 61 pacientes com AVC, participantes do Estudo da Mortalidade e Morbidade do AVC (EMMA) que ocorre no Hospital Universitário da Universidade de São Paulo, foram convidados a participar da validação da TICS-M, seis meses após o evento agudo. A TICS-M foi aplicada em três momentos: avaliação inicial (entrevista presencial), uma e duas semanas após a primeira avaliação. Na avaliação inicial, além da TICS-M, questionários adicionais foram aplicados para avaliar a cognição: MoCA (Montreal Cognitive Assessment), MEEM (Mini Exame do Estado Mental); e para a depressão, HDRS (Hamilton Depression Rating Scale). Todos os questionários foram aplicados por duas entrevistadoras treinadas para o estudo. A confiabilidade intra-observador da TICS-M foi testada através dos coeficientes de Pearson, Intraclasse e alfa de Cronbach. As características internas do TICS-M também foram avaliadas através de uma análise exploratória utilizando o método Análise de Componentes Principais. A validade discriminatória do instrumento para rastreamento de demência pós-AVC foi avaliada em comparação a MEEM pela análise da área sob a curva (AUC) determinada pela curva ROC. Foram calculadas sensibilidade e especificidade para o ponto de corte ideal para rastrear demência. Resultados: De maneira geral, a TICS-M traduzida para o português apresentou um bom entendimento dos itens na mostra de indivíduos não clínicos. Foi observada uma frequência de 23% sugestiva de demência pós-AVC. O nível de escolaridade esteve positivamente associado ao estado demencial rastreado pelo MEEM. O estado depressivo assim como outras características de base não se associou à demência sugerida pelo MEEM. A confiabilidade teste-reteste intra-observador revelou taxas quase totais nos três momentos avaliados (Pearson Coeficiente > 0,85, Coeficientes de Correlação Intraclasse > 0,85 e Coeficiente alfa de Cronbach: 0,96). A análise fatorial determinou três domínios: memória de trabalho e atenção; memória recente e de evocação e orientação. A área sob a curva (AUC) determinada para a TICS-M em comparação com MEEM foi de 0,89 (intervalo de confiança 95%: 0,80-0,98). O ponto de corte sugerido para TICS-M foi de 14 pontos (escala de 0-39 pontos) para rastrear demência com sensibilidade de 91,5% e especificidade de 71,4%. Resultados semelhantes foram observadas com o MoCA. Conclusão: A versão brasileira da TICS-M sugere ser um instrumento de pesquisa útil e confiável para rastrear demência em pacientes pós-AVC / Introduction: Stroke is one most important cause of neuropsychological disorders. An initial cognitive assessment performed by telephone resulting in an early diagnosis of cognitive impairment and dementia, reducing costs and time. Objective: To examine the psychometric properties of the Brazilian version of the Modified Telephone Interview for Cognitive Status Assessment (TICS-M) for assessment of dementia in post-stroke patients. Methods: Prior to validation of TICS-M in post-stroke patients, translation was performed for the Brazilian-Portuguese and cross-cultural adaptation of the original version of TICS-M in a non-clinical sample of 30 subjects. After this phase, 61 stroke patients enrolled in the Stroke Mortality and Morbidity Study (The EMMA study) that occurs at the University Hospital of the University of São Paulo, were invited to participate in this sub-study to validate the TICS-M six months after the acute event. The TICS-M was applied in three moments: first evaluation (personal interview), one and two weeks after of the first evaluation. At the first evaluation, beyond the TICS-M, additional questionnaires were applied to assess cognition: MoCA (Montreal Cognitive Assessment), MMSE (Mini-Mental Status Examination), and for depression, HDRS (Hamilton Depression Rating Scale). All questionnaires were administered by two trained interviewers for the study. Reliability of the TICS-M was tested by intra-observer rates using Pearson, Intraclass and Cronbach´s alpha coefficients. The internal characteristics of TICS-M were also evaluated by an exploratory analysis using Principal Component Analysis. The discrimination validity of the instrument to assess dementia was evaluated by comparison to the MMSE analysis of the area under the curve (AUC) determined by the ROC curve. Sensitivity and specificity for the ideal cutoff to assess dementia were calculated. Results: In general, the TICS-M translated into Portuguese version showed a good understanding of the items in non-clinical individuals. A frequency of 23% suggestive of post-stroke dementia was observed. The level of education was positively associated with dementia status assessed by MMSE. The depressive status, as well as, other baseline characteristics was not associated with dementia suggested by MMSE. Test-retest reliability intra-observer revealed almost total rates in the three evaluation moments (Pearson coefficient > 0.85, Intraclass Correlation Coefficient > 0.85 and Cronbach\'s alpha coefficient: 0.96). The factorial analysis determined three domains: working memory and attention, recent and recall memory and orientation. The area under the curve (AUC) determined by TICS-M compared to MMSE was 0.89 (95% confidence interval: 0.80-0.98). The cutoff suggested for TICS-M was equal or greater than 14 points (range 0-39 points) to assess dementia (91.5% sensitivity, 71.4 % specificity). Similar results were observed with the MoCA. Conclusion: The Brazilian version of TICSM suggests being a useful and reliable research instrument to evaluate dementia in poststroke patients in epidemiological studies
