L’utilisation des mesures subjectives en épidémiologie s’est intensifiée récemment, notamment avec la volonté de plus en plus affirmée d’intégrer la perception qu’ont les sujets de leur santé dans l’étude des maladies et l’évaluation des interventions. La psychométrie regroupe les méthodes statistiques utilisées pour la construction des questionnaires et l’analyse des données qui en sont issues. Ce travail de thèse avait pour but d’explorer différents problèmes méthodologiques soulevés par l’utilisation des techniques psychométriques en épidémiologie. Trois études empiriques sont présentées et concernent 1/ la phase de validation de l’instrument : l’objectif était de développer, à l’aide de données simulées, un outil de calcul de la taille d’échantillon pour la validation d’échelle en psychiatrie ; 2/ les propriétés mathématiques de la mesure obtenue : l’objectif était de comparer les performances de la différence minimale cliniquement pertinente d’un questionnaire calculée sur des données de cohorte, soit dans le cadre de la théorie classique des tests (CTT), soit dans celui de la théorie de réponse à l’item (IRT) ; 3/ son utilisation dans un schéma longitudinal : l’objectif était de comparer, à l’aide de données simulées, les performances d’une méthode statistique d’analyse de l’évolution longitudinale d’un phénomène subjectif mesuré à l’aide de la CTT ou de l’IRT, en particulier lorsque certains items disponibles pour la mesure différaient à chaque temps. Enfin, l’utilisation de graphes orientés acycliques a permis de discuter, à l’aide des résultats de ces trois études, la notion de biais d’information lors de l’utilisation des mesures subjectives en épidémiologie. / Recently, subjective measurements have increasingly been used in epidemiology, alongside the growing will to integrate individuals’ point of view on their health in studies on diseases or health interventions. Psychometrics includes statistical methods used to develop questionnaires and to analyze questionnaire data. This doctoral dissertation aimed to explore methodological issues raised by the use of psychometric techniques in epidemiology. Three empirical studies are presented and cover 1 / the validation stage of a questionnaire: the objective was to develop, using simulated data, a tool to determine sample size for internal validity studies on psychiatric scale; 2 / the mathematical properties of the subjective measurement: the objective was to compare the performances of the minimal clinically important difference of a questionnaire, assessed on data from a cohort study, computed using the classical test theory (CTT) framework or the item response theory framework (IRT); 3 / its use in a longitudinal design: the objective was to compare, using simulated data, the performances of a statistical method aimed to analyze the longitudinal course of a subjective phenomenon measured using the CTT or IRT framework, especially when some of the available items used for its measurement differ at each time of data collection. Finally, directed acyclic graphs were used to discuss the results from these three studies and the concept of information bias when subjective measurements are used in epidemiology.

INTRODUÇÃO: a resiliência é um construto associado às características pessoais que permitem a um indivíduo adaptar-se e superar situações adversas. Uma pessoa mais resiliente é aquela com maiores habilidades de se adaptar sob estresse, a despeito da carga de dificuldades enfrentada e de um contexto desfavorável no entorno. A Dispositional Resilience Scale (DRS-15) e a Connor-Davidson Resilience Scale (CD-RISC) tentam aferir a resiliência individual e já tiveram suas propriedades testadas em vários países da América do Norte, África, Europa e Ásia. OBJETIVO: traduzir, realizar a adaptação para o contexto cultural brasileiro e verificar a confiabilidade e a validade das escalas DRS-15 e CD-RISC. MÉTODO: uma metodologia com as etapas seqüenciais de tradução/retro-tradução/adaptação cultural/estudo de confiabilidade/estudo de validade foi utilizada. A adaptação cultural foi executada por um grupo de especialistas em epidemiologia, linguística, psiquiatria e tratamento da dor. A compreensão das versões culturalmente adaptadas foi testada com 65 pacientes adultos do grupo de avaliação pré-anestésica e do ambulatório geral de ansiedade do Hospital das Clínicas da FMUSP. Retro-traduções das versões finais foram aprovadas pelos autores principais das escalas originais. O estudo de validade foi conduzido pela aplicação conjunta de ambas as versões brasileiras das escalas, do Inventário de Sintomas de Stress para Adultos de Lipp (ISSL), do Self-report questionnaire (SRQ), da escala de incapacitação de Sheehan (SDS) e da Escala Graduada de Dor Crônica (CPG-Br) a 575 pacientes e acompanhantes adultos da mesma população. A confiabilidade teste-reteste foi avaliada por uma segunda aplicação das escalas de resiliência a 123 participantes, entre 7 e 14 dias após a entrevista inicial. RESULTADOS: entre os participantes da fase de validação, a idade média foi de 44 anos (amplitude de 18-93), com predomínio de mulheres (74%), e média de dez anos de estudo. A maioria dos entrevistados (93%) pertencia aos estratos socioeconômicos B e C. Três fatores e quatro fatores foram identificados por análise fatorial exploratória para as versões da DRS-15 e CD-RISC, respectivamente. O coeficiente alfa de Cronbach foi de 0,71 para a DRS, e de 0,93 para a CD-RISC, indicando melhor consistência interna para a segunda. A confiabilidade teste-reteste retornou coeficientes de correlação intra-classe de 0,81 e 0,86 para a DRS e CD-RISC, respectivamente. A correlação entre as duas escalas foi de 0,52. Observaram-se correlações negativas significativas entre os escores das escalas de resiliência e os escores para cinco das seis dimensões do ISSL, assim como para com os escores do SRQ e SDS (p < 0,001). Não houve correlação entre as escalas de resiliência e a CPG-Br. A CD-RISC encontrou correlações mais fortes que a DRS para com as variáveis de comparação externa. As duas escalas discriminaram resiliência menor para os pacientes dos ambulatórios psiquiátricos, em comparação aos dos ambulatórios não-psiquiátricos. Entre os pacientes psiquiátricos, os escores de resiliência foram significativamente menores para os pacientes com transtorno Borderline de personalidade, em comparação aos pacientes com transtorno de estresse pós-traumático. CONCLUSÃO: propriedades de consistência interna, estabilidade temporal e validade foram satisfatoriamente demonstradas para as versões brasileiras da DRS e da CD-RISC em uma amostra de pacientes e acompanhantes adultos dos ambulatórios do Hospital das Clínicas de São Paulo / INTRODUCTION: Resilience is a construct related to the personal characteristics that allow an individual to adapt and overcome adversity. A more resilient person is the one that exhibits greater abilities to adapt under stress, despite the burden of difficulties and of an unfavorable context. The Dispositional Resilience Scale (DRS-15) and the Connor-Davidson Resilience Scale (CD-RISC) are two scales to measure individual resilience, both of which have had psychometrics evaluated by researchers from the US, Africa, Europe and Asia. OBJECTIVE: To verify the reliability and validity of culturally adapted Brazilian Portuguese versions of the DRS-15 and CD-RISC. METHODS: The following stepwise methodology was used: translation / back translation / cultural adaptation / reliability study / validation study. Cultural adaptation was performed by an expert committee of epidemiologist, linguists, psychiatrist and pain specialists. Comprehension of the culturally adapted versions was tested through 65 interviews with adult patients from the pre-anesthetic consultation ambulatory and general ambulatory for anxiety disorders of Hospital das Clínicas of FMUSP. Back-translations of the culturally adapted versions were fully approved by the authors of the original scales. Validation studies were carried out by concurrent application of both the adapted versions of resilience scales, the Brazilian Stress Symptoms Inventory for Adults (ISSL), the Self-report Questionnaire (SRQ), the Sheehan Disability Scale (SDS) and the Chronic Pain Grade (CPG-Br) to 575 participants (outpatients and companions) from the same population. Test-retest reliability was studied by means of a second interview with 123 subjects, which took place between 7 and 14 days after the first one. RESULTS: Subjects of the validation phase were mostly women (74%), with an average of 44 years of age (18-93) and 10 years of formal schooling. There was a predominance of socioeconomic levels B or C (93%) on an A to E scale. Exploratory factor analyses resulted in a three-factor for the DRS and a four-factor solution for the CD-RISC. Alpha coefficients of 0.71 for the DRS and 0.93 for the CD-RISC indicated better internal consistency for the latter. Temporal stability was regarded as excellent, with intra-class correlation coefficients of 0.81 and 0.86 for the DRS and CD-RISC, respectively. Correlation coefficient between the two scales was 0.52. Significant negative correlations were observed between the scores of both resilience scales and five out of six dimensions of the ISSL, and so as between the resilience scales scores and those of the SRQ and SDS (p < 0.001). No correlation was observed between the resilience scales and the CPG-Br. The CD-RISC was more competent than DRS to depict such correlations. Both scales were able to discriminate differences in resilience scores of non-psychiatric and psychiatric patients, the latter presenting with lower scores. The group of borderline patients significantly presented with lower resilience scores in comparison with those of the post-traumatic stress disorder patients. CONCLUSION: Good reliability and validity were demonstrated with the Brazilian Portuguese versions of the DRS and CD-RISC as tested on a sample of adult ambulatory patients and their adult companions at Hospital das Clínicas, São Paulo

Contexte : L'évolution des pratiques en alcoologie, suivant le modèle des soins centrés sur la patient, permet de revisiter le concept de rémission pour une meilleure prise en compte du point de vue du patient, participant de façon prépondérante dans la définition de ses objectifs thérapeutiques et dans leur évaluation. Pourtant, peu de ces critères subjectifs de l’évaluation du devenir des patients ont véritablement inclus le patient dans leur développement. Jusqu'à récemment, les instruments mesurant la qualité de vie les plus utilisés en alcoologie étaient génériques, constitués d'items générés par les experts et s'appuyant sur la littérature existante, mais n'ayant pas impliqué de patient dans leur développement, c’est-à-dire dans la génération des items. Méthodes : nous avons réalisé une revue systématique de la littérature recensant les essais thérapeutiques randomisés testant une intervention chez les patients alcoolodépendants, et mesurant son efficacité sur la qualité de vie. Nous avons répertorié les dimensions explorées dans les instruments existants. Il a été montré que ces instruments n'exploraient pas de façon optimale l’impact de l’alcoolodépendance sur la qualité de vie. Sur ce constat, nous avons développé conformément aux recommandations de la Food and Drug Administration (FDA) sur le développement des « Patients-Reported Outcomes » une échelle spécifique au trouble d'usage d'alcool, à partir du vécu rapporté par les patients. Nous avons utilisé la méthode des groupes focus, réalisés en parallèle en France et en Grande-Bretagne auprès de 38 patients présentant un trouble d’usage d’alcool. Ces groupes ont pu générer un pool d’items, testés secondairement par des entretiens cognitifs individuels auprès de 31 patients, aboutissant à l’échelle finale « Alcohol Quality of life Scale » (AQoLS). Nous avons ensuite validé l’échelle AQoLS sur un échantillon de 285 patients français présentant un trouble d’usage d’alcool, recrutés dans des centres sélectionnés de façon aléatoire en France. Résultats : L’échelle développée comporte 34 items, répartis selon 7 dimensions : les relations sociales, les activités, les conditions de vie, s’occuper de soi, les émotions négatives, le sommeil et la perte de contrôle. L’analyse de l’échelle a pu confirmer 6 de ces sept dimensions, avec une répartition légèrement différente des items. La dimension « s’occuper de soi » a disparu au profit d’une nouvelle dimension, l’estime de soi. Les dimensions de contrôle et d’estime de soi sont novatrices dans un instrument de qualité de vie liée à la santé, chez l’adulte. L’échelle a montré de bonnes propriétés psychométriques, avec une bonne consistance interne (Cronbach = 0.96), et une corrélation modérée mais significative avec certains sous-scores de la SF-36 et l’EQ-5D. Un travail complémentaire qualitatif a pu illustrer les liens entre les différents domaines impactés, et notamment la proximité de perception dans les propos des patients, entre l’estime de soi, la perte de contrôle et les troubles cognitifs. Conclusion : L’évolution vers un modèle des soins centrés sur le patient permet d’envisager une conception différente de la rémission et de construire et valider une mesure de la qualité de vie se rapprochant des préoccupations des patients, l’échelle AQoLS. Deux dimensions novatrices ont été rattachées à ce concept : la perte de contrôle du point de vue du patient, et l’estime de soi. / Context : The evolution of practices in alcohol use disorder field, following the model of patient-centered care, lets revisit the concept of remission for a better consideration of the patient's point of view, participating predominantly in the definition of therapeutic objectives and in their assessment. Yet few of these subjective criteria of the evaluation of patient outcomes have actually included the patient in their development. Until recently, quality of life instruments the most used among patients with alcohol use disorder were generic ones, and their development and particularly generation of items did not involve patients, but rather experts and were based on existing literature. Methods : we conducted a systematic literature review identifying randomized clinical trials testing an intervention in alcohol-dependent patients, and measuring its effectiveness on quality of life. We have listed the dimensions explored in the existing instruments. It has been shown that these instruments did not optimally explore the impact of alcohol dependence on quality of life in this population. On this, we have developed a scale specific for patients with alcohol use disorder, following the recommendations of the Food and Drug Administration (FDA) on the development of "Patient-Reported Outcomes", namely involving patients extensively. We used the method of focus groups conducted in parallel in France and Great Britain with 38 patients with alcohol use disorder. These groups allowed the generation of a pool of items, secondarily tested by individual cognitive interviews with 31 patients, resulting in the final scale "Alcohol Quality of Life Scale" (AQoLS). We then validated the AQoLS scale on a sample of 285 French patients with alcoho use disorder, recruited from randomly selected centers in France. Results: The scale has 34 items developed, distributed in seven dimensions: social relationships, activities, living conditions, looking after self, negative emotions, sleep and loss of control. The validation study confirmed six of the seven dimensions, with a slightly different distribution of the items. The "looking after self" dimension disappeared in favor of a new dimension of self-esteem. Control and self-esteem dimensions are innovative in a health-related quality of life instrument in adults. The scale showed good psychometric properties, with good internal consistency (Cronbach = 0.96), and a moderate correlation with sub-scores of the SF-36 and EQ-5D. A qualitative complementary work could illustrate the links between the different affected areas, including the proximity in patients’ perception between self-esteem, loss of control and cognitive impairment. Conclusion : The move towards a model of patient-centered care allows considering a different approach of remission and to build and validate a measure of health-related quality of life close to the concerns of patients with a alcohol use disorder, AQoLS scale. Two innovative dimensions were attached to this concept: loss of control from the patient's perspective, and self-esteem.

However, parental satisfaction is also considered an important indicator. Satisfaction surveys are already carried out frequently, but the questionnaires are not evaluated in relation to validity and reliability. In the Netherlands, the Empowerment of Parents in the Intensive Care 30 (EMPATHIC-30) questionnaire was developed to assess parental satisfaction in UTIO. In Brazil, validated questionnaires were not found for this purpose, so our aim is to translate, culturally adapt and validate the content of EMPATHIC-30 to evaluate parents' satisfaction in Brazilian PICUs. Methods: : the translation and cultural adaptation was carried out according to the protocol of the translation and cultural adaptation group of the International Society for Pharmacoeconomic Research - ISPOR 2005. The content validation was carried out by a committee of experts. After that, the mean and standard deviation (SD) for all items were calculated, and the content validity coefficient (CVC) for each item and for the instrument as a whole. Conclusion: EMPATHIC-30 was translated and adapted culturally to the Brazilian population. Validation demonstrated a total above-average CVC, confirming the validity of the instrument content. / Introdu??o: As medidas de avalia??o da qualidade em Unidades de Terapia Intensiva Pedi?tricas (UTIP) s?o geralmente relacionadas a par?metros cl?nicos. Contudo, a satisfa??o dos pais tamb?m ? considerada um indicador importante. Pesquisas de satisfa??o j? s?o realizadas com frequ?ncia, por?m os question?rios n?o s?o avaliados em rela??o ? validade e ? confiabilidade. Na Holanda, foi desenvolvido o question?rio Empowerment of Parents in the Intensive Care 30 (EMPATHIC-30) para avaliar a satisfa??o dos pais em UTIP. No Brasil, n?o foram encontrados question?rios validados para este fim, desta forma, nosso objetivo ? traduzir, adaptar culturalmente e validar o conte?do do EMPATHIC-30 para avaliar a satisfa??o dos pais em UTIP brasileiras. M?todos: a tradu??o e adapta??o cultural foi realizada conforme protocolo do grupo de tradu??o e adapta??o cultural da Sociedade Internacional para Pesquisas Farmacoecon?micas ? ISPOR 2005. A valida??o do conte?do foi realizada por uma comiss?o de especialistas. Ap?s foram calculadas a m?dia e Desvio Padr?o (DP) para todos os itens, e o coeficiente de validade de conte?do (CVC) para cada item e para o instrumento como um todo. Resultados: na fase de adapta??o transcultural, as frases foram adaptadas de acordo com a sintaxe brasileira e sofreram poucas modifica??es. Na valida??o de conte?do, o CVC foi abaixo da m?dia em tr?s itens, dois foram mantidos no instrumento e um foi exclu?do. Conclus?o: o EMPATHIC-30 foi traduzido e adaptado culturalmente para a popula??o brasileira. A valida??o demonstrou um CVC total acima da m?dia, confirmando a validade do conte?do do instrumento.

Estudo do tipo metodológico com abordagem psicométrica que lida com a teoria e desenvolvimento de instrumentos de medição. O percurso metodológico norteou-se nos procedimentos teóricos, empíricos e analíticos para a elaboração de instrumento psicométrico (PASQUALI, 1998), e fundamentou-se em duas teorias da privacidade (WESTIN, 1970; ALTMAN, 1975), na teoria da territorialidade (ARDREY, 1966) e na teoria proxêmica (HALL, 1986). Os procedimentos teóricos compreenderam a definição do construto privacidade física no contexto hospitalar, em especial a exposição e manipulação corporal, o qual delineou-se a partir do referencial teórico adotado, da literatura pertinente e de estudo junto a 34 pacientes internados nos hospitais de Maringá-PR, com abordagem qualitativa, utilizando-se a análise de conteúdo (BARDIN, 2000). Esse estudo permitiu descrever a percepção do paciente hospitalizado sobre a privacidade em geral e sobre a privacidade física, identificando-se três categorias empíricas referentes à privacidade em geral, a saber, dignidade e respeito, espaço pessoal e territorial e autonomia, e com relação à privacidade física extraíram-se iguais categorias, acrescentando-se às anteriores a categoria intimidade e toque. Tais categorias compuseram os quatro domínios do instrumento em construção. O instrumento foi submetido à análise semântica e conceitual por um painel de juízes composto por sete peritos, e na seqüência a um pré-teste junto à população-alvo, resultando em um instrumento com 22 itens, tendo o domínio dignidade e respeito 8 itens, intimidade e toque e espaço pessoal e territorial 5 itens cada, e o domínio autonomia 4 itens. Os procedimentos empíricos englobaram a aplicação do instrumento construído, Escala de Satisfação do Paciente Hospitalizado com sua Privacidade Física (ESPH-PF), a uma amostra de 254 pacientes internados na rede hospitalar de Maringá- PR, entre novembro de 2007 e fevereiro de 2008. Os procedimentos analíticos englobaram a análise da consistência interna ( de Cronbach total de 0,68 e variação entre 0,35 e 0,60 nos domínios) e a validade de construto por meio da análise fatorial, extraindo-se seis fatores (57,6% da variância total) e optando-se por manter os quatro pré-estabelecidos (47,7% da variância explicada). A validade convergente do construto utilizando-se a correlação produtomomento de Pearson (p < 0,01) e aplicação da Escala do Sentimento frente à Invasão do Espaço Territorial e do Espaço Pessoal do Paciente Hospitalizado (EMS-FIETEP), contemplou o domínio espaço pessoal e territorial da ESPH-PF e confirmou o poder discriminativo de todos os 22 itens do instrumento. A validade discriminante do construto empregando o teste t de student (p < 0,05) não encontrou diferença estatística significante, exceto nos grupos extremos relativos à escolaridade. A análise psicométrica demonstra que a ESPH-PF pode ser aplicada para medir a satisfação do paciente com sua privacidade física no contexto hospitalar, sobretudo no que diz respeito à exposição e manipulação corporal. Os resultados obtidos junto a essa população não podem ser generalizados, porém comprovam a importância de se avaliar a satisfação do paciente com sua privacidade física, visto que o nível de satisfação revela, implicitamente, as preferências e necessidades dele por privacidade, e indiretamente também reflete o desempenho dos profissionais de saúde relativo à proteção e manutenção da privacidade no hospital. / The study is of a methodological type using the psychometric approach which deals with the theory of the development of measurement instruments. The methodological apparatus is based on empirical and analytical theoretical proceedings, to the development of a psychometric instrument (PASQUALI, 1998), and is grounded in two privacy theories (WESTIN, 1970; ALTMAN, 1975), on the territoriality theory (ARDREY, 1966) and on the proxemic theory (HALL, 1986). The theoretical proceedings entailed the definition of the physical privacy construct in hospital context, especially the exposure and body manipulation, drawing on the theoretical apparatus used, the related literature and a study with thirty-four patients admitted in hospitals in Maringá-PR, with qualitative approach, using the content analysis (BARDIN, 2000). This study allowed to describe the perception of the hospitalized patient as regards general privacy and physical privacy, identifying three empirical categories concerning general privacy, namely dignity and respect, personal and territorial space and autonomy, and as regards physical privacy the same categories were extracted, adding to the previous ones the category of intimacy and touch. Such categories composed the four domains of the instrument under construction. The instrument was subjected to semantic and conceptual analyses by a panel of judges composed by seven connoisseur, followed by a pretest with the target population, resulting in an instrument with 22 items, in which the domain dignity and respect had eight items, intimacy and touch and personal and territorial space had five items each, and the domain autonomy had four items. The empirical proceedings entailed the application of the constructed instrument, Satisfaction Scale of the Hospitalized Patient with his/her Physical Privacy (ESPH-PF), to a sample of 254 patients admitted in the hospital chain of Maringá-PR between November 2007 and February 2008. The analytical proceedings entailed the internal consistency analysis (-Cronbach total of 0,68 variation between 0,35 and 0,60 in the domains) and the construct validity by means of factorial analysis, extracting six factors (57,6% of total variation) and opting to maintain the four preestablished ones (47,7% of explained variation). The convergent validity of the construct utilizing the correlation product-moment of Pearson (p < 0,01) and the application of Feeling Scale before the Invasion of Territorial and Personal Space of the Hospitalized Patient (EMSFIETEP) contemplated the domain personal and territorial space of ESPH-PF and confirmed the discriminating power of all 22 items of the instrument. The discriminating validity of the construct employing the test t of student (p < 5005) did not find significant statistical difference, except for extreme groups regarding education. The psychometric analysis shows that the ESPH-PF can be applied to measure the patients satisfaction with his/her physical privacy, once the level of satisfaction implicitly reveals his/her privacy preferences and necessities, and also indirectly reflects the performance of health professionals as regards protection and maintenance of hospital privacy.

The purpose of the present work was to study hand impairments and manual ability in children with cerebral palsy (CP) as well as to clarify their relationship. Appraising the degree of hand impairments requires normative data to differentiate the real dysfunctions of CP children from the normal difficulties according to their age, sex, or handedness. As there is no normative data for gross manual and fine finger dexterity, a first experiment focused on the normal development of manipulative functions was conducted to establish these norms. A second experiment was carried out to develop and validate through the Rasch model a measure of manual ability in children with CP since such a measure was not yet available. The invariance of the ABILHAND-Kids questionnaire was also tested across relevant demographic and clinical subgroups of CP children. Finally, a third experiment was performed to quantify the hand impairments in children with CP and to investigate their relationship with manual ability as measured with the ABILHAND-Kids questionnaire. Hand motor impairments, markedly more prevalent than hand sensory impairments, were moderately correlated with manual ability measures and predicted 58% of their variance. Consequently, manual ability cannot simply be inferred from hand impairments and should be measured and treated per se. / L'objectif de ce travail était d'étudier les déficiences de la main et l'habileté manuelle chez les enfants infirmes moteurs d'origine cérébrale (IMOC) ainsi que de clarifier leur relation. Apprécier la gravité des déficiences de la main nécessite des données normatives afin de différencier les dysfonctionnements réels des enfants IMOC des difficultés normales compte tenu de leur âge, sexe, ou latéralité. Etant donné l'absence de normes quant à la dextérité manuelle grossière et la dextérité digitale fine, une première étude a été réalisée afin d'examiner le développement normal de ces deux types de dextérité. Des normes sur les dextérités manuelle grossière et digitale fine ont ainsi pu être établies. Une deuxième étude a été effectuée afin de développer et valider à travers le modèle de Rasch une mesure de l'habileté manuelle chez les enfants IMOC. L'invariance du questionnaire ABILHAND-Kids a également testée à travers différents sous-groupes démographiques et cliniques d'enfants IMOC. Enfin, une troisième étude a été réalisée afin de quantifier les déficiences de la main chez les enfants IMOC et d'investiguer leur relation avec l'habileté manuelle. Les déficiences motrices de la main, plus prévalentes que les déficiences sensitives, étaient modérément corrélées avec les mesures d'habileté manuelle et prédisaient 58% de leur variance. En conséquence, l'habileté manuelle ne peut être simplement inférée à partir des déficiences de la main et devrait donc être mesurée et traitée pour elle-même.

The topic of racism and prejudice is a very sensitive issue for many Canadians. This is primarily due to Canada's cherished image as a tolerant society leads even the most progressive people to adopt the belief that racism is comprised of only overt acts. However, what is not acknowledged by this old-fashioned view of prejudice is that the nature and expression of prejudice has evolved into a more covert form of prejudice known as modern prejudice (McConahay, 1986). This is particularly important because there is a well documented history of prejudice and discrimination of Aboriginal peoples in Canada, and without a proper understanding of the changing face of prejudice in Canada it is difficult to determine if there in fact has been a reduction in prejudiced attitudes towards Aboriginal peoples in Canada.<p> This study examines the criterion-related validity of the Prejudice Attitudes Towards Aboriginals Scale (PATAS) (Morrison, 2007) a 25 item (11 old-fashioned prejudice items and 14 modern prejudice items) newly developed measure of prejudicial attitudes towards Aboriginals developed using the theory of Modern Prejudice (McConahay, 1986). Four hundred and five undergraduate students completed a questionnaire including the PATAS, Right-wing Authoritarianism scale (RWA scale) (Altemeyer, 2007), Social Dominance Orientation scale (SDO5) (Pratto, Sidanius, Stallworth, and Malle, 1994), Motivation to Control Prejudice Reactions Scale (MCPRS) (Dunton and Fazio, 1997), and Form C of the Marlowe Crowne Social Desirability Scale (Renolds, 1982).<p> The results of this investigation revealed evidence attesting to the criterion-related validity of the PATAS. Participants who scored high on the PATAS also had high scores on the RWA scale, SDO5 scale, and tended to have a conservative political orientation. However, contrary to expectations, religious self schema was not found to be associated with PATAS scores. Practical applications and limitations of these findings are discussed as are possible directions for future research.

The topic of racism and prejudice is a very sensitive issue for many Canadians. This is primarily due to Canada's cherished image as a tolerant society leads even the most progressive people to adopt the belief that racism is comprised of only overt acts. However, what is not acknowledged by this old-fashioned view of prejudice is that the nature and expression of prejudice has evolved into a more covert form of prejudice known as modern prejudice (McConahay, 1986). This is particularly important because there is a well documented history of prejudice and discrimination of Aboriginal peoples in Canada, and without a proper understanding of the changing face of prejudice in Canada it is difficult to determine if there in fact has been a reduction in prejudiced attitudes towards Aboriginal peoples in Canada.<p> This study examines the criterion-related validity of the Prejudice Attitudes Towards Aboriginals Scale (PATAS) (Morrison, 2007) a 25 item (11 old-fashioned prejudice items and 14 modern prejudice items) newly developed measure of prejudicial attitudes towards Aboriginals developed using the theory of Modern Prejudice (McConahay, 1986). Four hundred and five undergraduate students completed a questionnaire including the PATAS, Right-wing Authoritarianism scale (RWA scale) (Altemeyer, 2007), Social Dominance Orientation scale (SDO5) (Pratto, Sidanius, Stallworth, and Malle, 1994), Motivation to Control Prejudice Reactions Scale (MCPRS) (Dunton and Fazio, 1997), and Form C of the Marlowe Crowne Social Desirability Scale (Renolds, 1982).<p> The results of this investigation revealed evidence attesting to the criterion-related validity of the PATAS. Participants who scored high on the PATAS also had high scores on the RWA scale, SDO5 scale, and tended to have a conservative political orientation. However, contrary to expectations, religious self schema was not found to be associated with PATAS scores. Practical applications and limitations of these findings are discussed as are possible directions for future research.
