Analyzing different levels of citizens‘ satisfaction using quantitative methods has a pivotal role in the process of
urban planning. Measuring the level of satisfaction with life quality is complicated and at the same time under the
influence of many factors. Therefore, for investigating more closely the issue, first, we reviewed the history of the
life quality and the definitions of life quality provided by different scholars through a geographical perspective. The
indices used to measure the life quality and the main approaches to life quality were also taken into consideration.
The approach taken here is an American one. To predict the mental health of the citizens of Kaleybar, the citizens
were asked to fill in the GHQ-28 (General Health Questionnaire) and then the WHOQOL-BREF (The World Health
Organization Quality of Life) questionnaire to have an understanding of their mental health and life quality indices.
The data collected were analyzed using Multiple Regression Analysis to determine the effect of life quality indices
on the mental health of the citizens.
