catalaEs presenta com s’ha constituit una comunitat social d’investigacio (CSI) amb 48 persones majors institucionalitzades des de la responsabilitat social universitaria (RSU) i des d’una perspectiva humanista. En aquesta CSI es va valorar el benestar psicologic de les persones institucionalitzades amb metodes quantitatius i qualitatius, i amb una proposta d’investigacio-accio participativa (IAP). S’inicia, aixi, un proces d’innovacio epistemologica, amb escassos antecedents, a l’hora d’investigar i entendre el benestar de les persones majors. Aquesta primera experiencia de la CSI aporta observacions sobre els canvis de les dimensions del benestar de Ryff durant el proces d’envelliment dins de la institucio particip de l’estudi. Concretament, apareix l’augment del domini de l’entorn i la baixada de l’autonomia i del proposit en la vida. Tambe s’aporten dades qualitatives que permeten entendre aquests canvis. EnglishThis article introduces how a Social Research Community (CSI) has been constituted with 48 institutionalized elderly from the University Social Responsibility (MSW) and from a humanistic perspective. In this CSI, the psychological well-being of the institutionalized people were assessed with quantitative and qualitative methods from a proposal of Participatory Action Research (PAR). It begins thus an epistemological innovation process, with little precedent, when it comes to research and understand the welfare of the elderly. This first experience of CSI provides observations on the dimensional changes of Ryff's welfare during the aging process within the institution to participate in the study. Specifically, it shows the increase of the Dominion of Environment and fall of Autonomy and Purpose in Life. Also qualitative data are provided to help understand these changes.
