Quality of life is a noticeable concept in urban deteriorated areas where people suffer from multidimensional and complex problems. According to Tehran Renovation Organization (TRO), a deteriorated area is defined just by three physical indicators of fine grain, lack of permeability and lack of durability. But deteriorated areas suffer from other physical as well as socio economic problems which need to be considered in planning processes. Consequently, assessing the QOL in deteriorated inner areas is the main purpose of this paper to survey the overall life satisfaction, to extract main and different aspects of QOL and to determine the extent that overall life satisfaction is explained by different components of life. neighbourhood, located in Tehran metropolis, one of the most deteriorated neighbourhoods in the city has been chosen as a case for this study. Forty nine indicators which cover different dimensions of quality of life have been selected through literature review. Multi-stage sampling technique for sampling has been applied. In first stage by application of Cochran sampling method, the required sample size has been determined. Then by use of systematic sampling method, questionnaires have been distributed among the residents of the neighbourhood. After data collection, a confirmatory factors analysis indentified 11 factors as identical components of QOL. A stepwise regression is performed to investigate the overall life satisfaction and the extent that QOL is determined by identified domains. Results show that traffic, mobility, housing and infrastructure are the most important aspects of QOL which affect the overall life satisfaction of the residents of the surveyed deteriorated neighbourhood. Also a negative relationship was found between overall satisfaction and private life. The findings of the study also show that the three physical indicators used by the TRO for identifying the deteriorated areas are not adequate to address the deterioration issues. Other physical and socio economic aspects which are incorporated with different QOL dimensions also affect the overall life satisfaction, which have to be addressed in planning and policy making to upgrade quality of life for people in deteriorated neighbourhoods.
生活质量在城市衰败地区是一个值得关注的概念，在这些地区人们面临多维度且复杂的问题。根据德黑兰改造组织（TRO）的定义，衰败地区仅由三个物理指标来界定，即细粒度、缺乏渗透性和缺乏耐久性。但衰败地区还存在其他物理以及社会经济问题，这些问题在规划过程中需要加以考虑。因此，评估衰败内城区的生活质量是本文的主要目的，旨在调查总体生活满意度，提取生活质量的主要和不同方面，并确定生活的不同组成部分对总体生活满意度的解释程度。位于德黑兰大都市、该市最衰败的社区之一被选为该研究的案例。通过文献综述选择了涵盖生活质量不同维度的49个指标。抽样采用多阶段抽样技术。在第一阶段，应用科克伦抽样方法确定所需样本量。然后采用系统抽样方法，在该社区居民中发放问卷。数据收集后，通过验证性因素分析确定了11个因素作为生活质量的相同组成部分。进行逐步回归以研究总体生活满意度以及生活质量由所确定领域决定的程度。结果表明，交通、流动性、住房和基础设施是生活质量的最重要方面，它们影响着被调查衰败社区居民的总体生活满意度。此外，还发现总体满意度与私人生活之间存在负相关关系。研究结果还表明，TRO用于识别衰败地区的三个物理指标不足以解决衰败问题。与不同生活质量维度相关的其他物理和社会经济方面也会影响总体生活满意度，在规划和政策制定中必须加以解决，以提升衰败社区居民的生活质量。
