    Introduction: School bullying has sparked considerable research interest, leading to the development of specific measures aimed at assessing both traditional bullying and cyberbullying (CB). Objective: To identify evidence of validity for the European Bullying Intervention Project Questionnaire (EBIPQ) and the European Cyberbullying Intervention Project Questionnaire (ECIPQ) in a sample of Ecuadorian adolescents. Method: A cross-sectional descriptive and psychometric study analyzing the construct validity, internal consistency, and convergent validity of both instruments. Sample: 341 adolescent students (56% female, 44% male), aged 14 to 19 years (M = 15.72; SD = 0.85), from different cities in Ecuador. Results: Oblique fit models with two dimensions per instrument provide the best factor representation. They also demonstrate adequate internal consistency across their dimensions and a high correlation between the two questionnaires. Conclusion: The EBIPQ and ECIPQ prove to be valid, reliable, and relevant instruments for measuring bullying and cyberbullying among adolescents in Ecuador.

    To analyze whether gender is a source of variability in the General Self-Efficacy Scale (GSES) using Classical Test Theory (CTT) and Item Response Theory (IRT) in a sample of Ecuadorian adults. This is an instrumental study that assesses factorial validity and Measurement Equivalence (ME) across gender using CTT, while IRT is used to estimate item discrimination [a], difficulty [b], and differential item functioning (DIF). A total of 485 adults participated, with 44.9% male and 55.1% female, aged 18 to 53 years (M = 24.29; SD = 7.61). The unifactorial structure of the GSES was confirmed and measurement invariance was established at the thresholds (scalar) level across gender. Furthermore, there are no significant differences (p <.05) in the latent means of the groups. The item parameters for [a] and [b] were found to be adequate, with no evidence of gender-based DIF in the items. The GSES is a reliable scale for use in studies involving Ecuadorian adults, and gender does not significantly affect its measurement propertie
