*Result*: Cyber Child‐to‐Parent Violence: Assessment and Prevalence According to Adolescents' and Parents' Reports.

*Introduction: Unlike other forms of violence, such as bullying or dating violence, which have been studied both offline and online, Child‐to‐Parent Violence (CPV) has primarily been analyzed in offline contexts, with research on its online form still in its early stages. Moreover, no standardized instruments currently exist to assess Cyber‐CPV. Thus, the primary objectives of this study were to develop and evaluate the psychometric properties of the Cyber‐Child‐to‐Parent Violence Questionnaire‐Adolescent (Cyber‐CPVQ‐A) and to assess the prevalence of and gender differences in Cyber‐CPV from the perspective of adolescents (Study 1) and their parents using the Cyber‐Child‐to‐Parent Violence Questionnaire‐Parent (Cyber‐CPVQ‐P) (Study 2). Methods: A total of 1597 adolescents participated in Study 1 (49.8% female, 45.5% male, and 0.7% identifying as other; Mage = 14.18, SD = 1.59). 91.3% of the participants were from Spain. In Study 2, 563 parents participated (72.5% mothers and 27.5% fathers; Mage = 49.00, SD = 4.87), of whom 86.9% were Spanish. Results: In Study 1, a Confirmatory Factor Analysis (CFA) supported a bifactor structure comprising of a general Cyber‐CPV factor and two specific factors: one for CPV toward the mother (Cyber‐CMV) and another toward the father (Cyber‐CFV) based on the adolescent‐reported version (Cyber‐CPVQ‐A). In Study 2, a CFA confirmed a unidimensional structure for the parent‐reported version (Cyber‐CPVQ‐P). Conclusions: Both scales demonstrated strong internal consistency. The prevalence of Cyber‐CPV was high in the community population. This study provides two valid and reliable instruments for assessing Cyber‐CPV in adolescents and parents, enabling a more comprehensive measurement of CPV. [ABSTRACT FROM AUTHOR]*
