Validation de la version canadienne-française du Life Orientation Test-Revised

Abstract

The "Life Orientation Test-Revised" (LOT-R) is used to evaluate the personal disposition toward optimism. Since the test is written in English and based on an American population, it cannot be used to conduct research on optimism with the French-Canadian population. Thus, following a translation of the LOT-R into French and a subsequent evaluation of its cross-cultural equivalence, the French-Canadian version of the LOT-R was administered to 204 francophone university students. The internal consistency was .76, a result that is deemed satisfactory and comparable to the internal consistency score of .78 obtained by Scheier et al. A test-retest score after 5 weeks revealed a highly acceptable temporal stability score of .74 (p < .001). The results of the confirmatory factorial analyses indicated that the French-Canadian version of the LOT-R has a similar structure to the original version of oie instrument with a one factor model allowing error terms from the positive test items to correlate with each other. The French-Canadian version of the IJOT-R can now be used to study optimism in a French-Canadian population. Copyright 2008 by the Canadian Psychological Association.
