From concerns of mental health problems and behavioural issues of residents of high-rises, this research tries to explore the association of interactional spaces (the spaces of interaction in a high-rise housing) with dimensions of social cohesion (the social relations) of the residents. Presuming social cohesion is an important determinant of their mental health. To have both the researchers’ and users’ perspectives while an investigation, this research incorporates perception of the residents, analysis of layout plan, behaviour observation and space syntax analysis. Later, with the help of hierarchical linear regression model it identifies the significant attributes and uses of interactional spaces (both at outdoor and indoor) that facilitate or inhibit social cohesion. The finding indicates that the arrangement and use of the streets and tot-lots within a housing complex have a significant contribution in strengthening social cohesion of the residents. Further, more than actual use, the opportunities of a chance encounter and opportunities of use of the spaces appear to be more effective. The findings of the research would have a wider application not only in high-rise group housing but other instances as well.

从对高层居民心理健康问题和行为问题的关注出发，本研究试图探讨互动空间（高层住宅中的互动空间）与社区的社会凝聚力（社会关系）的关系。居民。假定社会凝聚力是他们心理健康的重要决定因素。为了在调查时同时具有研究人员和用户的观点，本研究结合了居民的感知，布局计划分析，行为观察和空间语法分析。后来，借助分层线性回归模型，它确定了促进或抑制社会凝聚力的交互空间（室外和室内）的重要属性和用途。调查结果表明，住宅区内街道和杂物场的布置和使用对于增强居民的社会凝聚力具有重要作用。此外，比实际使用更多的是，偶然相遇的机会和使用空间的机会似乎更为有效。研究的结果不仅将在高层团体住房中得到更广泛的应用，而且在其他情况下也将得到更广泛的应用。
