Psychometric evaluation of the satisfaction with life scale in Togo: A three-step approach

IntroductionThe Satisfaction with life scale (SWLS) developed by Diener, Emmons, Larsen, and Griffin (1985) is considered the most widely used psychometric scale for assessing life satisfaction. Despite plethora of cross-cultural research that provided evidences of its robustness, none was conducted in French-speaking sub-Saharan countries such as Togo.ObjectiveAccordingly, the purpose of the present study was to investigate the validity of the SWLS extensively among Togolese college students (n = 460) in a three-step approach from 2012 to 2014.Method and resultsFirstly, social representations of well-being were explored qualitatively. Then, the original version of the SWLS was administered. Based on the results we gathered, a scale item was altered. Psychometric properties of the revised version of the SWLS were examined, revealing adequate construct validity, reliability, temporal stability, measurement invariance across gender, convergent validity with a single measure of life satisfaction, and discriminant validity with various life domain satisfactions.ConclusionLimitations and implications in life satisfaction measurement are also discussed with regards to the Togolese cultural context.
