Measuring Quality of Life in the Neighborhood: The Cases of Air-Polluted Cities in Tunisia

The objective of this paper is to study the quality of life in the neighborhood by developing a scale to measure the perceived environmental quality of life. Items of the scale were produced using semi-structured interviews. Three main dimensions of environmental quality of life (EQL) were recognized by an exploratory factor analysis applied on 732 participants. This factor structure was then subjected to a confirmatory factor analysis performed on a second sample of 791 people. The satisfactory internal consistency of the three EQL dimensions, the good fit of the measurement model to the data and the stability of the factorial structure all confirm the excellent psychometric qualities of the designed scale.
