Studies examining the effects of perceived parental rejectful attitudes during childhood and emotional deprivation on problematic Internet use based on inter-factorial analysis are limited. The aim of this research is to examine the effects of the above-mentioned factors on problematic Internet use in people aged 18 years and over. This study used quantitative methods and convenience sampling. The sample consisted of 341 individuals aged 18 years and older. Data collection tools included a personal information form, perceived parental attitudes scale-child form, Young Internet addiction test short form, and Young schema scale short form-3. According to the results obtained in this study, there is a positive correlation between perceived rejectful parental attitudes in childhood, emotional deprivation, and problematic Internet use. Additionally, it was observed that perceived rejectful parental attitudes during childhood had a positive direct effect on problematic Internet use, and emotional deprivation played a positive and partial mediating role in this relationship. Finally, it has been observed that various sociodemographic and social skill factors have a preventive effect on emotional deprivation and problematic Internet use. Various recommendations were made regarding the results obtained at the end of this study.
