Structural relationships among happiness scales: A second order factorial study

Our intent in this study was to investigate structural relationships among happiness scales, and to determine whether the happiness construct could be represented adequately by a single score index. Second order principal factors analyses were computed on six data sets representing eight samples of subjects where the variables were comprised of global or sub-global indices of happiness. Single factor solutions were obtained from every analysis. The findings were interpreted as, (1) supporting a hierarchical, rather than an orthogonal multicomponent, model of relationships among happiness scales and, (2) indicating that the construct can be represented adequately by a single score index in social indicators research.
