The aim of this research is to examine the attachment levels of preschool children considering their relationships with their parents and screen use habits. The study is designed based on quantitative research methods and a correlational survey model. The sample group of the research consists of 231 children aged 36–69 months and their parents from preschool education institutions affiliated with the Ministry of National Education. The simple random sampling method was used to form the research sample. The Parent–Child Relationship Scale, Incomplete Stories with Doll Family Scale, Technology Use Habits Scale, and Problematic Media Use Measure were used to collect the research data. Using quantitative data analysis methods, normality tests were initially conducted, and parametric tests were applied during the analysis process. As a result of the research, it was observed that there was a negative and statistically significant relationship between the positive parent–child relationship and other variables (negative parent–child relationship, technology addiction, and problematic media use). A positive and statistically significant correlation was found between the negative parent–child relationships and technology addiction and problematic media use. A positive and statistically significant correlation was found between technology addiction, and problematic media use. No statistically significant difference was found between the groups in the analysis of the parent–child relationship, technology addiction, and problematic media use dimensions according to the “attachment style” variable.
