The Satisfaction with Life Scale SWLS was developed for the overall assessment of life satisfaction as a global cognitive judgment, rather than the measurement of satisfaction in specific domains (e.g. success in school, material wealth, health). In order to achieve the objectives of this study that concentrated upon investigating its psychometric properties and assessing its applicability in Syrian context, the instrument under consideration was translated into Arabic and subjected to several methods and procedures of reliability and validity. Factor analysis by using the principal components\' method and Varimax Rotation was also conducted . Validation data collected, depending upon a variety of samples (N=856), displayed satisfactory coefficients of internal consistency and test-retest reliability. The study also established convergent and divergent validity by using nine criterion measures, as well as discriminate validity based upon contrasted groups method. Factor analysis conducted supported validity by displaying one general factor. This factor which was accounted for 56,12% of the total variance confirmed the unidimensionality of the scale that was observed in other studies. The overall findings suggest the applicability of the Arabic version of SWLS in Syrian context. The researcher , therefore, is encouraged to propose this version to be used in different fields such as research, cross-cultural and cross-national comparisons, as well as clinical settings to some extent. The researcher also suggests that the Arabic version of the scale should be submitted to further investigations.
