This chapter describes a mixed-method study aimed to explore how civilians living in the line of fire over a period of 12 years experienced and perceived the impact of their exposure to warfare on their couple relationship. In the quantitative part of the study the role of couple resilience, and loss and gain of couple resources as mediators between the level of exposure and the couple relationship was explored. Data were collected from 61 individuals living next to the border between Israel and the Gaza Strip and 112 individuals living some distance from the border. The results revealed no differences between the groups on the couple relationship. However, significant differences were found between the groups in their reporting of negative, positive, and no-implications of the security threat on the couple relationship. The high exposure group reported significantly higher negative and positive implications of the security situation on the couple relationship, whereas the limited exposure group scored significantly higher on their reporting of no-implications. Couple resilience and increased couple resources were found to be mediators between level of exposure and no-implications of the security situation on the couple relationship. Couple resilience was also found to be a mediator between the level of exposure and negative implications, whereas increased couple resources was found to be a mediator between the level of exposure and positive implications. The qualitative part aimed at exploring the way couples construct their experience of the exposure to warfare, using grounded theory methodology. Data were collected through in-depth semi-structured interviews with 14 couples. Five main themes were gathered and organized into a model constituting a continuum between no impact and an adverse impact of the security situation on the couple relationship. The significance of these results to understanding couples living under ongoing external stress was discussed.
