Psychometric quality of the Subjective Well-Being and Life Conditions scale in Mexican adults

In psychology, the study of the subjective well-being construct has become more complex by incorporating, among others, indicators of human development and living conditions. The aim of the work was the construction and validation of the Subjective Well-Being and Living Conditions scale (BISCOV) with Mexican adults. The study was carried out in two phases. In the first the instrument was built, its construction and theoretical relevance were evaluated by five judges and it was applied to 80 people selected in a non-probabilistic way. With this pilot version, its reliability and factorial structure were analyzed. The final version of the BISCOV was applied to 436 people selected in a non-probabilistic way. The scale had adequate reliability (Chronbach’s a between .8 and .9) and the structural model showed a good fit (CFI= .98; TLI= .97; RMSEA= .06). The psychometric characteristics allow us to have a good quality instrument to assess subjective well-being and living conditions in the Mexican population.
