The study’s aim was to obtain evidence of validity of the Learning Self-Regulation Questionnaire (LSRQ) internal structure and to verify metric invariance compared with a previous research study. The participants were 237 university students from the first three academic semesters of a private university in three Peruvian cities (two in the North of Peru, and one in Lima). The analysis was performed by a semi-confirmatory factor analysis, specifying as comparison matrix: a) the configuration derived from a previous study, and b) the free estimation loadings factors. The results indicate that two dimensions represent the instrument structure satisfactorily; but the metric invariance compared to a previous study was not satisfactory. The re-specification of the model, by removing two items with factorial complexity problems and the free estimation of the items, was successful. These results are discussed so as to the interpretation of their scores and the lack of metric invariance. / El objetivo del estudio fue obtener evidencias de validez de la estructura interna del Cuestionario de Autorregulación del Aprendizaje (Learning Self-Regulation Questionnaire; LSRQ) y verificar la invarianza métrica comparada con un estudio previo. Los participantes fueron 237 estudiantes universitarios de los tres primeros ciclos académicos de una universidad privada, procedentes de tres ciudades del Perú (dos del norte y una de Lima). El análisis se realizó mediante un análisis factorial semiconfirmatorio, especificando como matriz de comparación (a) la configuración derivada de un estudio previo, y (b) la estimación libre de las cargas factoriales. Los resultados indican que dos dimensiones representan satisfactoriamente la estructura del instrumento; pero la invarianza métrica respecto a un estudio previo no fue satisfactoria. La reespecificación del modelo, mediante la eliminación de dos ítems con problemas de complejidad factorial y la estimación libre de los ítems, obtuvieron resultados satisfactorios. Se discuten estos resultados en el marco de la interpretación de sus puntajes y la falta de invarianza métrica.

It is presented the structure and psychometric studies of the “School Motivation Questionnaire”. The SMQ is a self-report questionnaire with 101 items, organized in sixteen scales that measure the students´ goal orientations, the perceived classroom goal structures, the perceived teacher’s autonomy support and the use of learning strategies. Twelve scales are adapted from the “Learning Climate Questionnaire”, “Perceptions of Instrumentality” and “Cuestionário a Estudiantes”. Four scales and five additional items are created new. The psychometric studies rely on a convenience sample consisting of 9th and 12th grade students ( = 485) of Portuguese schools. The factorial and construct validity, verified through several exploratory factorial analyses to the data, presents a final solution of six factors, labelled Strategies (F1), Teacher Extrinsic Goals (F2), Student Extrinsic Goals, Externally Regulated (F3) Teacher Intrinsic Goals (F4), Student Extrinsic Goals, Internally Regulated (F5), and Student Intrinsic Goals (F6). The six-factor solution explains a significant variance of the scale results (53.95%). Good coefficients of internal consistency are obtained for all factors, never below (.858; F6). In sum there is strong evidence to support the multi-dimensionality of SMQ, upholding that the data obtained is exploratory and applies for future validation studies. / Se presenta la estructura y los estudios psicométricos del “Cuestionario de Motivación Escolar“. El CME es un cuestionario de auto informe con 101 ítems, organizados en dieciséis escalas que miden las orientaciones de las metas de los estudiantes, la percepción de las estructuras de las metas de clase, las percepciones del apoyo del profesor a la autonomía y el uso de estrategias de aprendizaje. Doce escalas son una adaptación del “Learning Climate Questionnaire”, “Perceptions of Instrumentality” y “Cuestionario a Estudiantes”. Cuatro escalas y cinco frases adicionales se crearon para este estudio. Los estudios psicométricos se basan en una muestra de conveniencia compuesta por estudiantes de los grados 9 y 12 (N = 485) de las escuelas portuguesas. La validez factorial y la construcción ha sido verificada a través de varios análisis factoriales exploratorios de los datos, y presenta una solución definitiva de seis factores, siendo Estrategias (F1), Metas extrínsecas de los docentes (F2), Metas extrínsecas de los estudiantes, reguladas externamente (F3), Metas intrínsecas de los docentes (F4), Metas extrínsecas de los estudiantes ,reguladas internamente (F5), y Metas intrínsecas de los estudiantes (F6). La solución de seis factores explica una variación significativa de los resultados de la escala (53,95%). Se encontraron buenos coeficientes de consistencia interna para todos los factores, nunca por debajo de (.858; F6). En suma, hay una fuerte evidencia para apoyar la multidimensionalidad del CME. Estos resultados son exploratorios y servirán como una base para estudios de validación posteriores.

Measures of adult attachment developed in English have been translated and validated in multiple Spanish-speaking countries, yet to this date no self-report adult attachment instrument has been systematically examined for validation with Latinos/Hispanic Americans. The present study examined psychometric properties of a Spanish version of a widely used adult attachment scale, the Experiences in Close Relationships Scale (ECRS), with a bilingual college student sample. Following the dual-language split half (DLSH) quantitative method of evaluating semantic equivalence, 209 bilingual, Latinos/Hispanic American college students recruited from a large public university completed a DLSH version of the ECRS (half English, half Spanish). Internal consistency reliability and DLSH reliability were within acceptable limits, although significantly smaller than coefficients of the English ECRS completed by a large Caucasian sample (n = 459); 3- to 8-week test-retest reliability was also adequate. Exploratory factor analysis revealed a two-factor solution with 35 items accounting for 40% of the variance, which was similar to the English ECRS. Convergent validity was supported by findings that showed significant associations of attachment dimensions with social self-efficacy, self-esteem, depressive symptoms, and comfort with self-disclosure, but not interpersonal trust. Evidence for discriminant validity was found in that attachment dimensions were not significantly associated with social desirability. Theoretical implications, limitations, and future directions of the study will be discussed based on adult attachment theory and cross-cultural perspectives.

The failure to translate evidence into clinical practice has been repeatedly highlighted. This failure is partly attributed to disregarding the context within which healthcare is delivered. The aim of this thesis was to develop and psychometrically evaluate the Context Assessment for Community Health (COACH) tool, and, through that process, provide opportunities to measure aspects of context perceived to be important for Knowledge Translation (KT) interventions in low- and middle-income countries (LMIC). All four studies in this thesis were mainly undertaken in Quang Ninh province, Vietnam during 2008–2014. Study II, however, was also conducted in four other LMICs (Bangladesh, Nicaragua, South Africa, and Uganda). Study I employed inductive content analysis of 16 focus group discussions to explore the influence of context in a community-based facilitation intervention in Vietnam. Studies II and III reported on the development of the COACH tool and assessment of its psychometric properties. Study IV used the COACH tool in a survey among health workers in Vietnam. To date, three sources of evidence regarding validity of the COACH tool have been provided, that is, test content, response processes, and internal instrument structure, with promising psychometric characteristics. The COACH tool could be used as means of characterizing aspects of context ahead of KT interventions, for tailoring KT strategies, and for further understanding of the results of KT interventions. / Context Assessment for Community Health

Après avoir analysé au travers d'une recherche exploratoire et clinique, certains des facteurs de protection mis en jeu lors d'un traumatisme, une investigation approfondie de la littérature internationale a été menée afin de mettre en évidence la pertinence d'un instrument permettant d'appréhender la présence d'un panel plus large de facteurs de résilience. Face auxlimites des outils psychométriques actuels et en vue de les pallier, une échelle de mesure a été élaborée. Ainsi, cette thèse sur travaux rapporte les étapes de développement et de validation d'un outil construit afin d'évaluer les facteurs de protection concourant à la résilience. Une analyse factorielle exploratoire des données a été conduite auprès de 299 participants francophones dans le but d'éprouver la structure de l'I.F.R-40 (Inventaire des Facteurs de Résilience). La validité convergente, la stabilité temporelle de même que la cohérence interne de l'outil ont fait l'objet d'une évaluation. Les résultats obtenus soutiennent une structure en trois dimensions (facteurs de protection personnels, familiaux et extra-Familiaux) et appuient la validité ainsi que la fidélité de l'I.F.R-40. D'autres analyses ont également été menées afin devalider la structure factorielle de l'Inventaire des Facteurs de Résilience (I.F.R-40) au moyen d'une A.F.C (Analyse Factorielle Confirmatoire). Les analyses réalisées confirment la présence de trois facteurs, interprétés en termes de facteurs de protection familiaux, facteurs de protection individuels et facteurs de protection extrafamiliaux. L'étude de la validité divergente confirme les liens prédits entre l'I.F.R-40 et l'échelle composite de dépression de Berndt et Kaiser (1999). Enfin, l'I.F.R-40 différencie les adolescents exposés à un traumatisme présentant des scores de dépression à la MDI-C de ceux ne manifestant pas de dépression. Ainsi, l'I.F.R-40 est une échelle tridimensionnelle présentant des propriétés psychométriques satisfaisantes. Les résultats sont discutés à la lumière de leurs implications à la fois théoriques et pratiques. / After having analysed through an exploratory and clinical research, some protection factors playing a part after a traumatism, an in-Depth investigation of international literature was conducted in order to bring to light the relevance of an instrument enabling to comprehend the presence of a larger set of resilience factors. Confronted with the limits of actual psychometric tools and in order to overcome them, a measurement scale has been worked out. Thus, this thesis reports the development and validation steps of a tool constructed with the aim of evaluating the protection factors working together towards resilience. An exploratory factorial data analysis was conducted on 299 French-Speaking participants to test the structure of the I.R.F-40 (Inventory of Resilience Factors). The convergent validity, the temporal stability as well as the internal consistency of the tool have been assessed. The results obtained approve of the three dimension structure (personal, familial and extra-Familial protection factors) and support the validity as well as the reliability of the I.R.F-40. Other analyses have also been conducted in order to validate the factorial structure of the Inventory of Resilience Factors (I.R.F-40) thanks to C.F.A (Confirmatory Factorial Analysis). The analyses conducted confirm the presence of three factors, interpretedin terms of familial protection factors, individual protection factors and extra-Familial protection factors. The study of the divergent validity confirms the predicted links between the I.R.F-40 and Berndt and Kaiser’s composite depression scale (1999). Finally, the I.R.F-40 differentiates the adolescents exposed to a traumatism and who have depression scores atMDI-C to those who experience no depression. Therefore, the I.R.F-40 is a three dimension scale presenting satisfactory psychometric properties. The results are discussed in the light of both their theoretical and practical implications.

L’addiction à Internet a fait l’objet de nombreuses études à travers le monde durant les vingt dernières années. Pourtant aucun consensus au sujet de sa définition ou de ses critères diagnostiques n’a encore été admis, soulevant ainsi de nombreux débats. Ce travail a pour objectif d’étudier la conceptualisation de l’addiction à Internet principalement au travers de ses outils d’évaluation, et de combler un manque de données empiriques au sein d’échantillons français.Étude 1 – Objectif : Déterminer le nombre d’outils de mesure de l’addiction à Internet et mettre en avant leurs qualités psychométriques. Résultats : Quarante-cinq outils mesurant l’addiction à Internet ont été identifiés dont seulement dix-sept ayant été évalués plus d’une fois en termes de propriétés psychométriques. La plupart des échelles existantes nécessitent de plus amples travaux de validation. Bien que critiqué, l’Internet Addiction Test (IAT) est l’échelle présentant le plus de supports empiriques. Cependant, de nombreuses échelles prometteuses requièrent un examen plus approfondi. Étude 2 – Objectif : Évaluer les qualités psychométriques de l’Online Cognition Scale (OCS). Résultats : Les analyses factorielles de l’OCS suggéraient un meilleur ajustement du modèle avec une solution à 5 facteurs (27 items), comparé au modèle original (36 items). Nos résultats mettent en avant une excellente consistance interne et des corrélations inter items et test-retest satisfaisantes. Les scores de l’OCS étaient significativement corrélés avec ceux de l’IAT, du temps passé en ligne et des symptômes dépressifs au cours des deux passations. Étude 3 – Objectifs : Évaluer les qualités psychométriques de la Generalized Problematic Internet Use Scale-2 et la pertinence du modèle d’Utilisation Problématique Généralisée d’Internet (UPGI) au sein d’étudiants français. Résultats : Les résultats de la modélisation en équations structurelles soutiennent ce modèle conceptuel de l’addiction à Internet, et un bon ajustement du modèle aux données. Les qualités psychométriques de la version française de la GPIUS-2 étaient satisfaisantes, notamment la fiabilité, et les validités convergente et concurrente, confirmant l’utilité de cet outil multidimensionnel. Étude 4 – Objectif : Explorer la relation entre l’UPGI et les Utilisations Problématiques Spécifiques d’Internet (UPSI). Résultats : Nos analyses mettent avant des relations significatives entre l’UPGI, les symptômes psychopathologiques et la plupart des UPSI, avec de nombreuses différences en fonction du genre et de l’âge. Alors que les scores d’UPSIcommunication prédisaient ceux d’UPGI chez l’ensemble des participants, ceux d’UPSIrecherche d’informations et jeux en ligne, ainsi que les symptômes dépressifs n’étaient significatifs que chez les femmes, les hommes et les jeunes adultes, et l’UPSIconsommation de vidéo/musique et le temps passé en ligne uniquement chez les femmes et les jeunes adultes. / Internet addiction has been the subject of numerous studies worldwide, during the last twenty years. Yet, no consensus on its definition or diagnosis criteria has been admitted, which therefore is triggering numerous debates. The present research aims to study the conceptualization of Internet addiction mainly through its assessment tools, and to fill in the lack of empirical data among French samples.Study 1 - Aim: To assess the measurement tools for Internet addiction and their psychometric properties. Results: Forty-five tools assessing Internet addiction were identified, of which only seventeen had been evaluated more than once in terms of their psychometric properties. Most of the existing scales for Internet addiction require further validation work. Despite criticism, the Internet Addiction Test (IAT) appears to be the scale with the most empirical support. However, numerous promising scales warrant further examination.Study 2 - Aim: To evaluate the psychometric properties of the Online Cognition Scale (OCS). Results: Confirmatory factorial analyses showed that the 4-factor solution did not demonstrate satisfactory fit but the 5-factor model was found to better fit the data. Our results revealed that the scale scores demonstrated excellent internal consistency and satisfying inter-item correlation and test-retest reliability. The OCS was significantly correlated with the IAT, time spent online and depressive symptoms at both time points.Study 3 - Aim: To evaluate the psychometric properties of the Generalized Problematic Internet Use Scale-2 and the relevance of the Generalized Problematic Internet Use (GPIU) model among French users. Results: Path analysis provided support for this conceptual model of problematic Internet use, and a good fit to the data. The psychometric properties of the French version of the GPIUS-2 were satisfying, including reliability, concurrent and convergent validities, suggesting the usefulness of this multidimensional tool.Study 4 - Aim: To explore the relationship between GPIU and Specific Problematic Internet Uses (SPIU) Results: Our analysis revealed significant relationships between GPIU, psychopathological symptoms and most of SPIU, with many differences according to gender and age. SPIUcommunication scores significantly predict GPIU scores among the whole sample, whereas SPIUinformation seeking and gaming, and depressive symptoms were only significant among women, men and young adults, and SPIUconsumption of video/music and time spent online, among women and young adults.

The psychometric properties of a parent-completed developmental questionnaire for children at 6 years of age were investigated. Currently, few developmental screening instruments for 6-year-old children have been validated, and most available instruments are designed to be completed by teachers or professionals, who may not witness an optimal sample of child behavior. Thus a screening tool with robust psychometric properties is needed that can be completed by parents or caregivers who see the child across settings and time. A total of 169 children participated in this research. Data collection included online and paper completion during well child visits, in clinics, at preschool programs, and in parents' homes. A random subsample was asked to participate in reliability and convergent validity studies. Cronbach's alpha coefficient was used to measure internal consistency reliability. Results indicated a Cronbach alpha of agreement with the Child Development Inventory was used. A Confirmatory Factor Analysis with categorical data confirmed the 6-Year Ages and Stages Questionnaire domains, e.g., communication, personal social, fine motor, gross motor, and problem solving. Limitations of the current study and directions for future research are discussed. / 10000-01-01

La presente investigación tuvo como objetivo analizar las propiedades psicométricas de la Escala de Dificultades en la Regulación Emocional (DERS) de Gratz y Romer (2004). La muestra estuvo compuesta por 253 jóvenes (27.7% hombres y 72.3% mujeres) universitarios de carreras de ciencias de la salud con edades comprendidas entre los 18 y 25 años (M = 21.70, DE = 1.75). De dicha muestra, 120 jóvenes fueron encuestados de manera virtual y 133, fueron encuestados de forma presencial. En primer lugar, se analizó la validez basada en la estructura interna mediante el análisis factorial exploratorio (AFE) donde se obtuvo un KMO de .86 y una prueba de esfericidad de Bartlett que fue estadísticamente significativa (p < .001). Como resultado del AFE de la DERS se obtuvo 5 factores (Dificultades en la Regulación de Impulsos, Aceptación Emocional, Consciencia Emocional, Interferencia en Conductas y Claridad Emocional) de los 6 establecidos originalmente que explicaron el 44.96 % de la varianza. Respecto a las relaciones de convergencia con la Escala de Autorregulación Emocional, se encontró correlaciones no tan altas, aunque estadísticamente significativas entre las dimensiones. Respecto a la dimensión de reevaluación cognitiva se correlaciona negativa, baja e inversamente con dos dimensiones de la DERS (Dificultades en la regulación de impulsos y Falta de aceptación emocional). Asimismo, la dimensión de supresión emocional se correlaciona positiva, baja y directamente con una dimensión (Falta de conciencia emocional). En cuanta la confiabilidad los valores del alfa de Cronbach fueron aceptables (entre .72 y .86), así como los del coeficiente omega (entre .74 y .87). Finalmente, se concluye que la escala cuenta con adecuadas propiedades psicométricas para su uso en muestras similares. / The objective of this research was to analyze the psychometric properties of the Difficulties in Emotional Regulation Scale (DERS) by Gratz and Romer (2004). The sample consisted of 253 young people (27.7% men and 72.3% women) university health sciences aged between 18 and 25 years (M = 21.70, SD = 1.75). Of this sample, 120 young people were surveyed virtually and 133, were surveyed in person. First, the validity of the internal structure was analyzed by exploratory factor analysis (AFE), where a KMO of .86 was obtained and a Bartlett sphericity test was statistically significant (p <.001). As a result of the DIE of the DIE, we have obtained 5 factors (Difficulties in the Regulation of Impulses, Emotional Acceptance, Emotional Consciousness, Behavior Interference and Emotional Clarity) of the 6 elements that explain 44.96% of the variance. Regarding the relationships of convergence with the Emotional Self-Regulation Scale, there are correlations not so high, although statistically significant between the dimensions. Regarding the cognitive reassessment dimension, it correlates negatively, low and inversely with the dimensions of the DERS (Difficulties in the regulation of impulses and lack of emotional acceptance). Also, the dimension of emotional suppression correlates positively, lowly and directly with one dimension. In terms of reliability, the values of Cronbach's alpha were acceptable (between .72 and .86), as well as the omega coefficient (between .74 and .87). Finally, it is concluded that the scale has psychometric properties for its use in similar samples. / Tesis

<p>Att vara aktiv och klara av att utföra sitt arbete har en central betydelse för en individs hälsa och välbefinnande. Begreppet arbetsförmåga är ett komplext begrepp som beskrivs som flerdimensionellt. Vid bedömning av arbetsförmåga är det viktigt att bedömaren använder sig av tillförlitliga metoder som syftar till att hjälpa individen med sin fortsatta rehabilitering. Syftet med studien är att kartlägga olika bedömningsinstrument som mäter arbetsförmåga i olika avseenden. Bland annat vilket syfte instrumentet har, vilken datainsamlingsmetod instrumentet använder samt vilka psykometriska egenskaper som har prövats för instrumentet. För att besvara syftet gjordes en systematisk litteraturstudie med sökning i följande databaser: PubMed, CINAHL, Scopus och OT-seeker vilket resulterade i tio artiklar. En manuell sökning utfördes för att komplettera den initiala sökningen vilket resulterade i ytterligare sex artiklar. Resultatet visar att sju instrument kunde identifieras som på olika sätt mäter en individs arbetsförmåga. Majoriteten av dem har ett tydligt syfte samt är förankrade i en teoretisk grund och är prövade utifrån olika psykometriska egenskaper. Författarna har konstaterat att begreppet arbetsförmåga saknar enhetlig definition och är ett komplext begrepp. I diskussionen föreslås en samverkan av olika instrument som framkommit i studien för att tydliggöra och bistå bedömningen av en individs arbetsförmåga.</p> / <p>Being active and able to perform one’s work is of central importance to an individual’s health and wellbeing. Work capacity is a complex concept that is described as multidimensional. When assessing an individual’s work capacity, it is of great importance to use reliable methods designed to help the individual with his continuing rehabilitation. The purpose of this study was to identify existing assessment instruments for measuring work capacity in different ways, considering for example: the purpose of the instrument, the method for data collection, and the psychometric properties tested for the instrument. A systematic literature review was performed by searching the following databases; PubMed, CINAHL, Scopus, and OT-seeker.  The search resulted in ten articles. A complementary manual search was conducted, producing six additional articles. The contents of the 16 articles identified seven instruments, all of which measured an individual's work capacity in different ways. The majority of the instruments had a clear purpose, were anchored in a theoretical basis, and were tested on different psychometric properties. The authors found that the concept of work capacity has no single definition and is a complex concept. The discussion suggests the combined use of various instruments that emerged in the study to clarify and assist in the assessment of an individual’s work capacity.</p>
