Adaptation and validation of the MSLSS of multidimensional life satisfaction with a sample of adolescents

The goal of this study is to adapt and validate the Spanish version of the Multidimensional Students' Life Satisfaction Scale (MSLSS; Huebner, 1994a). The scale has been validated with a sample of 339 secondary education students from Gipuzkoa. For this purpose, a Principal Component analysis and a process of item selection were carried out on the data together with internal and temporary reliability analyses, and analyses of construct (convergent) and concurrent validity. The results show that the reliability of the instrument and its construct, convergent, and concurrent validity provides us with a valid instrument to assess adolescents' satisfaction with five specific domains: family, friends, self, school and living environment.
