grounded theory

This paper aims to explore how mobile phone technology shapes interactions between couples and creates a controversial atmosphere in marital life. To achieve this, we conducted 30 in-depth interviews with married individuals in Isfahan, Iran. After coding and categorizing the data using the grounded theory method, we identified "insecurity" as a core category. Feeling insecure is largely influenced by one's interpretation of their partner's "mobile phone etiquette" and "social media behavior". Insecurity manifests in four main dimensions: “emotional insecurity”, “relationship insecurity”, “individual insecurity”, and “domestic insecurity”. We noted that the marital life context, including trust and sexual satisfaction plays a crucial role in how couples perceive and interpret each other's use of mobile phones. However, gender is the most significant factor affecting individuals' perception of mobile phone, their interpretation of their spouse’s use, and their experience of insecurity as a result. This research utilizes social analysis to examine the effects of technology on family life. The research findings hold both academic and practical implications. Professionals involved in the field of family and couples' relationships can benefit from this paper to deepen their understanding of the role and significance of mobile phones in contributing to conflicts within marital life.
