A life satisfaction scale for use with national adult samples from the USA,Canada and Mexico

This paper describes the steps we took to develop a measure of life satisfaction which appears useful for analyses of adult sample survey data from the United States, Canada, and Mexico. Our procedure is factor analysis, and our data are drawn from the 1981–82 and 1991–92 World Values Surveys conducted in the three countries. The result is a six-variable composite measure which meets the following conditions: the constituent items have face validity, the factor structure is similar across countries and also across sub-groups within countries, the factor structure is also similar in 1981–82 and 1991–92, and the factor score based on these structures is highly correlated with variables that are customarily good predictors of life satisfaction and happiness. On the basis of these results, we will be confident in using the life satisfaction measure for future multivariate analyses of the data base aimed at explaining variation in satisfaction. For the same reasons, we would recommend the life satisfaction measure for others' research with the rich World Values Surveys data base.
