Design and Validation of an Evaluation Checklist for Organizational Readiness for Evaluation Capacity Development

Walker-Egea, Connie F. 09 October 2014 (has links)
Evaluation capacity development (ECD) has been acknowledged as a system of processes to help organizations achieve sustainable evaluation practice. Examining the existing evaluation capacity of an organization before starting an ECD process is necessary and will increase the possibilities of success, determined by the establishment or strengthening of an evaluation system into the organization. In response to this need, this study involved the designing of the Organizational Readiness for Evaluation Capacity Development (ORECD) checklist and its initial validation, using a mixed method research design. The study was conducted in four phases, including: (a) the design of the ORECD checklist based on a review of the literature; (b) a review of the ORECD checklist by five experts to obtain face and content validity evidences, with emphasis on relevance and clarity of the items and how well the items fit the corresponding component; (c) a pretesting about the appropriateness of the wording of the items and format of the ORECD checklist by a sample of doctoral graduate students with formal training in evaluation and professional evaluators; and (d) a field study with 32 nonprofit organizations to determine the utility and benefits of using the ORECD checklist and potential improvements to the instrument. This phase generated information about the psychometric properties as well as consequential validity evidence. Findings indicated that the ORECD checklist has great potential to determine the readiness of an organization to develop evaluation capacity, as demonstrated by the feedback received from various groups of participants, establishing face, content, and consequential validity. Results from the psychometric analysis showed correlations that, for the most part, suggested that the components are measuring aspects of the same construct. In addition, the alpha for most of the components supported the reliability of the ORECD checklist. The two components with alphas close to but below .70 required modifications in order to improve their reliability. Also, it was necessary to modify or reword some of the items. Ongoing efforts should provide information about how the changes made to the ORECD checklist are working and additional validity evidences as the one that can be obtained through factor analysis. This will allow the exploration of the underlying structure of the ORECD checklist and its components. It is expected that the ORECD checklist can be a contribution to the body of literature about ECD helping to address organizational readiness in order to support and sustain the development of evaluation capacity within organizations.

L'utilisation de la musique comme support de nouveaux apprentissages dans le vieillissement normal et la maladie d'Alzheimer

Moussard, Aline 04 1900 (has links)
L’objectif de ce travail de thèse est d’évaluer le potentiel de la musique comme support mnémotechnique pour l’acquisition de nouvelles informations chez des personnes âgées saines et atteintes de la maladie d’Alzheimer (MA). Les bénéfices de la musique sur la cognition ont souvent été mis en évidence, y compris chez des populations âgées ou atteintes de démence. Parallèlement, chez des sujets jeunes, l’idée que la musique peut servir de support pour la mémoire a été largement débattue. Pourtant, très peu d’études ont posé cette question auprès de populations âgées ou dans la démence, malgré le besoin persistant de stratégies d’intervention dans ce domaine. Dans le présent travail, deux études sont menées dans une cohorte de 8 participants atteints d’un stade léger de la maladie d’Alzheimer, et 7 participants âgés sains appariés en âge et niveau de scolarité. La première étude porte sur la mémoire verbale, et compare l’apprentissage et la rétention de paroles (textes inconnus) présentées de manière récitée ou chantée. Lorsque les paroles sont chantées, différents degrés de familiarité de la mélodie sont contrastés. Aussi, l’action motrice étant intimement liée à l’écoute musicale, nous contrastons deux procédures d’apprentissage impliquant (ou non) la production synchronisée des paroles à mémoriser pendant l’encodage : le participant est invité à chanter à l’unisson avec un modèle (ou à écouter simplement sans chanter). Les résultats de cette étude sont présentés et discutés dans les deux premiers articles de la partie expérimentale. Ils suggèrent globalement que la musique n’aide pas l’apprentissage en rappel immédiat ; un effet délétère est même observé lorsque la mélodie utilisée est non familière. Par contre, la musique favorise la rétention à long terme des paroles, principalement pour les participants MA. Elle ne semble cependant pas interagir avec la procédure d’apprentissage impliquant le chant à l’unisson. La seconde étude porte sur l’apprentissage de séquences de gestes. Suivant la même logique que dans la première étude, nous explorons l’influence d’un accompagnement musical (versus apprentissage en silence) et d’une procédure d’apprentissage avec production synchronisée (versus observation) des gestes durant l’encodage. Les résultats (article 3) ne montrent pas non plus d’interaction entre l’accompagnement et la procédure d’apprentissage, mais différents effets de chaque composante sur les deux groupes de participants. Effectuer les gestes en synchronie avec un modèle lors de l’encodage est bénéfique pour les sujets Contrôles, mais plutôt délétère pour les participants MA. Par contre, l’accompagnement musical favorise davantage l’apprentissage chez les sujet MA que chez les Contrôles. En discussion générale, nous discutons les implications de ces résultats pour la neuropsychologie fondamentale et clinique, et proposons notamment différentes recommandations visant à maximiser ces effets et à les rendre pertinents pour l’usage thérapeutique en stimulation cognitive. / This thesis research aims to test the potential of music as a mnemonic support for new learning in normal elderly and Alzheimer’s disease (AD) participants. Several studies have highlighted the beneficial effects of music on cognition in aging and dementia. At the same time, in young adults, the idea that music could serve as a mnemonic support is highly debated. Yet, very few studies addressed this question in aging or dementia. In the present work, we conduct two studies in a cohort of 8 mild Alzheimer’s disease and 7 matched control participants. The first study concerns verbal memory, and compares learning and different retention delays of lyrics (unknown texts) that are either spoken or sung. When lyrics are sung, different degrees of melody familiarity are contrasted. Moreover, as motor activity is strongly related to music, we compare two learning procedures that are either synchronized or not with the production of these lyrics during encoding: 1) participants sing in unison with the model or 2) participants hear the model without singing. Results of this study are presented and discussed in the first two articles of the experimental section. Globally, music does not show aid for learning measured in immediate recall; we even observed a harmful effect when lyrics are sung on a non-familiar melody. But music helps long-term retention of lyrics, particularly for AD participants. Nevertheless, music does not clearly interact with learning procedure involving unison singing. The second study of the thesis investigates the learning of gesture sequences. Similarly to the first study, we explore influence of music versus silence as background accompaniment, and synchronized production versus observation of gestures during encoding. Results (article 3) showed again no interaction between background accompaniment and learning procedure, but different effects of each variable on both groups. Learning gestures with synchronized production is beneficial for normal controls, but harmful for AD participants. On the other hand, musical accompaniment led to greater benefit for AD participants than for controls. In the general discussion, we present the implications of these results for fundamental and clinical neuropsychology. We propose some recommendations to maximize these effects and make them relevant for therapeutic care.
