This study examined the psychometric properties of the Brief Multidmensional Student Life Satisfaction Scale (BMSLSS: Seligson et al., 2003) with elementary school children. The participants included 518 elementary school students in grades three through five in a Southeastern US state. The students completed the following measures: the BMSLSS, the Students' Life Satisfaction Scale (SLSS: Huebner, 1991a), the Children's Social Desirability Questionnaire (CSDQ: Crandall et al., 1965), and the Positive and Negative Affect Schedule-Children's Version (PANAS-C: Laurent et al., 1999). The results revealed acceptable internal consistency reliability, construct validity and concurrent validity for the BMSLSS. Overall, the use of the BMSLSS for research purposes was supported on a preliminary basis for this age group for research purposes. The study also investigated the usefulness of weighted importance ratings in the prediction of global life satisfaction judgments. Children's ratings of the importance of the specific domains, whether viewed separately or combined with ratings of levels of life satisfaction, did not enhance the prediction of global life satisfaction. The usefulness of such a brief measure for the assessment of positive indicators of well-being in large-scale national and international studies is highlighted. Recommendations for future research are delineated.
