"I.IntroductionThe residential satisfaction can be defined as the experience of pleasure or gratification deriving from living in a specific place(Bonauito,2004). Just as global satisfaction, it includes elements that are affective and cognitive(Fleury-Bahi,1997)but also physical, social and human(Bonnes and al, 1997).Thus, residential satisfaction would be based on a global evaluation of various aspects of the housing.The IQURP is a questionnaire of 144 items grouped into 20 scales, each of them measuring a dimension of the psychological construct of residential satisfaction (eg. quality of the sociocultural activities in the neighborhood). The degree of agreement or disagreement is indicated by a Likert scale of 7 points.HypothesisThe main aim of our study is the adaptation of an italian psychometric assesment tool to the french culture.Because of the statistical method we will use, we expect:-to obtain less dimensions in the french 'IQURP' than the original.-that some explanatory dimensions of the residential satisfaction IQURP will be different from their equivalent in French.II.The adaptation of a assessment instrumenta)IssueAssessment tools by means of questionnaires and others are taking an important place in the research field of social psychology. However the variety of languages for communication in Europe for example restrict the applicability of psychological measures because such tools need to take the cultural specificity in account.b)MethodologyThe transcultural adaptation must garanty the sensibility and specificity of the original instrument and integrate the cultural singularities of the targeted culture.The transcultural adaptation follows 3 consecutive steps (Vallerand, 1989):a.Create and test a previous translation of the assesment toolb.Control the validity of the translationc.Adapt the scores obtained with the translated tool to the french context and if necessary develop new standards.We first create an experimental version of the IQURP using the method of the reversed translation. Then we try to compare the italian factorial model of the IQURP to the french mode. To this purpose, we use the software STATISTICA to perform a principal components analysis to detect meaningful underlying dimensions.The data are collected on a general population of 400 subjects.III. OutcomesWe are able to observe that the two factorial structures are quite similar. Yet we can see some differences between these two models of the residential satisfaction. Indeed these results show a reduction of the number of dimensions in the french version (17 "french" factors versus 20 "italian" factors). Four dimensions from the original IQURP are explained by the two global factors in the french version and one disappears.This dimensional reduction seems to come from the cultural and urban differences between these two countries but also from the particularities of the IQURP itself.
