This study conducts a narrative literature review to establish a conceptual foundation for Technology-Facilitated Gender-Based Violence (TFGBV) and to analyze the characteristics and psychological implications of its various subtypes. TFGBV refers to gender-based violence perpetrated through digital and information and communication technologies, encompassing various forms such as Image-Based Sexual Abuse (IBSA), doxxing, cyberstalking, Technology-Facilitated Coercive Control (TFCC), and sextortion. The main findings of this study are as follows. First, TFGBV represents a multilayered and intersecting spectrum of violence that cannot be reduced to a single category. The conceptual boundaries between terms are often ambiguous, leading to confusion in terminology and gaps in policy implementation. Second, TFGBV should not be viewed merely as a “digital issue” but rather as a structural form of gender-based violence, in which sexist social systems are reproduced and reinforced through technology. Third, existing research has disproportionately focused on IBSA, while psychological investigations into other forms—such as TFCC, sextortion, and doxxing—remain in their early stages. This imbalance risks undermining the theoretical and practical foundations necessary for effective intervention and policy development. Future research should work toward a more refined analysis of the boundaries and intersections among various forms of TFGBV, while expanding empirical inquiries into their psychological impacts to inform survivor-centered models of care. Interdisciplinary collaboration is also essential to establish contextually appropriate terminology and policy frameworks, particularly within the Korean sociocultural landscape.
