Despite this, many affected students do not receive treatment, underscoring the need for preventive strategies. In respose, the CORE program, an internet-based intervention, was developed to enhance resilience and coping skills among college students. The present study, part of the ICare project (EU-634757), aims to assess the effectiveness of the CORE intervention in improving resilience and reducing symptoms of anxiety and depression in comparison to a Waiting List (WL) condition. The study was registered at ISRCTN (ISRCTN13856522). In the study the unguided internet-based intervention (CORE) was compared to a WL control group in a multicenter two-arm, single-blind, randomized controlled trial (RCT) conducted in Spain, Germany, and Switzerland. Questionnaire based evaluations occurred at baseline (BL), 8 weeks (post-intervention), 6 and 12 months after randomization. A total of 493 students with low levels of resilience participated in the study. Participants in the intervention group gained access to an internet-based program aiming to enhance resilience by learning to cope with stressors in daily life, promote self-empowerment, and improve well-being. Participants were instructed to engage in six interactive modules delivered weekly in a sequential order. The program's therapeutic content was developed following the Ryff model of well-being. The primary outcome measure used was the Connor-Davidson Resilience Scale (CD-RISC-25). Additionally, anxiety and depressive symptomatology, coping strategies, and well-being were measured. Participants in the CORE condition reported a significant increase in resilience compared to WL condition (Differences post-BL: d = 0.34, p = .0005; 6 M-BL: d = 0.24, p = .0171; 12 M-BL: d = 0.33, p = .0031). Although, a general time trend towards improvement in the resilience was observed in both groups. Participants in the CORE condition, compared to those in the WL condition, showed a significant reduction in anxiety symptoms in the short and long term (differences post-BL: d = 0.30, p = .0015; 6 M-BL: d = 0.18, p = .0857; 12 M-BL: d = 0.23, p = .0312) and depression in the short term. Furthermore, participants in CORE condition showed a significant improvement in positive functioning measurements, such as well-being and self-compassion compared to WL condition. (Differences post-BL: d = 0.25, p = .0123; 6 M-BL: d = 0.16, p = .1505; 12 M-BL: d = 0.13, p = .1835). Adherence to fully complete the intervention was approximately 59 %. In conclusion, our study revealed promising outcomes for the CORE program, indicating its efficacy. These results position the CORE program as a valuable and validated tool in fostering resilience, offering promising ways for addressing mental health challenges in academic settings. 000150775 536__ $$9info:eu-repo/grantAgreement/EC/H2020/634757/EU/Integrating Technology into Mental Health Care Delivery in Europe/ICare$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 634757-ICare 000150775 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000150775 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000150775 700__ $$aFranke, Marvin 000150775 700__ $$aGörlich, Dennis 000150775 700__ $$aGarcia-Palacios, Azucena 000150775 700__ $$aBaños, Rosa 000150775 700__ $$aJacobi, Corinna 000150775 700__ $$aBerger, Thomas 000150775 700__ $$aSchaub, Michael P. 000150775 700__ $$aKrieger, Tobias 000150775 700__ $$aEbert, David D. 000150775 700__ $$aBotella, Cristina 000150775 7102_ $$14009$$2680$$aUniversidad de Zaragoza$$bDpto.
