MULTIDIMENSIONAL AND TEMPORAL MATTERING: THE ITALIAN ADAPTATION OF THE MATTERING IN DOMAINS OF LIFE SCALE

Mattering in Domains of Life Scale (MIDLS) is a 27 items scale to measure people’s perception of mattering in terms of feeling valued by others and adding value to others. The scale considers mattering as a multidimensional construct, across several life domains such as personal, interpersonal, occupational, and community. Each MIDLS domain is measured on a temporal continuum. A national sample of 3180 Italian people, reduced to a final sample of 2600 cases following data cleaning, was involved. Confirmatory factor analysis (CFA), within the framework of covariance-based structural equation modelling (CB-SEM), revealed that the best structure of Italian MIDLS is a bifactor solution, with a general mattering factor and eight domain-specific factors. High standardized factor loadings, along with high levels of omega hierarchical for the general factor and omegaS for the domain-specific factors show that the Italian MIDLS presents optimal psychometric proprieties in terms of dimensionality of the scale as well as reliability.
