Using the EAST model, three types of nudges (affective, cognitive, and behavioral) were applied through targeted messages to families, along with gamification for children to encourage the consumption of healthy foods and reduce the use of ultra-processed products. The intervention was implemented over three weeks and evaluated through systematic observations, a pretest-posttest survey on purchasing habits, and the PANAS affectivity scale. The results showed significant improvements in families' perception of health benefits (p < 0.001) and ease of preparation (p = 0.008). Additionally, an increase in the nutritional quality of lunchboxes was observed, with positive effects across all measurements. However, a decrease in caregivers' positive affect (p < 0.001) was recorded, suggesting the need to address emotional factors in future interventions. The findings suggest that nudges can improve eating habits and the nutritional quality of school lunchboxes, although psychological and contextual aspects should be considered in the design to achieve sustainable long-term changes.Publicación Intervención comportamental para moderar el uso del celular en clase por parte de estudiantes de una universidad de la ciudad de Medellín(Universidad EAFIT, 2025) Álvarez Lince, Camilo; Peralta Vélez, Ana MaríaPublicación Intervención comportamental tipo MINDSPACE para fortalecer las capacidades de comunicación efectiva en equipos técnicos : caso Odinsa(Universidad EAFIT, 2025) Álvarez Galindo, Jimmy Mauricio; Arroyave Velásquez, Viviana; López Aguirre, Lina María; Úsuga Arcila, Gloria CarolinaThis paper presents a behavioral intervention based on Nudges and Boost to improve the effective communication of Odinsa's technical teams. Using MINDSPACE and the Boost framework, a mixed approach was applied. The results show significant improvements in intonation, rhythm, posture and other aspects (Pretest: 19.19, Posttest: 24.75, p=0.000). The effect size (d=-2.454) confirms the relevance of the change, validated by parametric tests.Publicación MOTIVATOR-COLOMBIA : adaptación y evaluación de impacto en las competencias comunicacionales de profesionales de salud en Sura(Universidad EAFIT, 2025) Ceballos Ramírez, Laura María; Lemos Hoyos, MariantoniaPublicación La autodeterminación como capacidad motivadora para la adopción de conductas de gestión del bienestar propio(Universidad EAFIT, 2024) Zuluaga Noreña, Andrea; Pérez Villar, Lucía; Echeverri Álvarez, JonathanPublicación Intervención comportamental para aumentar la capacidad psicológica y motivación reflexiva de los estudiantes de pregrado que han cometido faltas contra la integridad académica(Universidad EAFIT, 2024) Rodríguez Moreno, Juliana; Molina Hurtado, Luisa Fernanda; Arboleda Durán, Yessica; Echeverri Álvarez, JonathanPublicación Intervención en madres gestantes de la comuna 13 de Medellín, vinculadas a los servicios de unidad administrativa especial buen comienzo de 2024, que busca mejorar los conocimientos y habilidades de extracción y conservación de leche materna(Universidad EAFIT, 2024) Londoño Osorio, Johana Alexandra; García Munoz, Carolina; Pemberty Montoya, María Dorancy; Torres Cadavid, SusanaPublicación Reducción de barreras y ampliación de beneficios, para aumentar la afiliación de trabajadoras remuneradas del hogar a la seguridad social(Universidad EAFIT, 2023) Londoño Jaramillo, Sara; Montoya Jaramillo, SaloméPublicación Estrategia comportamental para aumentar los espacios de desconexión en personal de enfermería, gerontología y cuidadoras en un hogar gerontológico de Medellín(Universidad EAFIT, 2024) Múnera Quintero, Victor Alfonso; Aguirre, David Alejandro; Lemos Hoyos, MariantoniaThis study aimed to design, implement, and evaluate a behavioral intervention using the EAST Framework with the goal of improving the burnout index by increasing disconnection behaviors among nursing assistants, gerontology workers, and caregivers at a Gerontological Home specializing in degenerative diseases (dementia) in Medellín. The intervention consisted of four components: 1. A physical space called the Disconnection Zone, 2. Videos called Wellness Capsules, 3. A WhatsApp group named Conscious Well-being, and 4. Another WhatsApp group called Sharing Well-being. The intervention was evaluated through a qualitative workshop, as initial high desirability prevented participants from reporting burnout levels at the beginning of the intervention. The results indicate that the Disconnection Zone was well received by the healthcare staff, and the disconnection groups were also positively valued, though variability in their use was observed. Additionally, the disconnection videos became a key tool for those experiencing unexpected moments of unrest and stress, due to their easy access and brevity, which allowed them to be used as a quick strategy to increase moments of disconnection for the healthcare staff at the Gerontological Home.Publicación Intervención comportamental tipo nudge para incrementar la participación de los estudiantes en las elecciones a representante estudiantil de posgrado en la universidad EAFIT (Colombia) para el periodo 2024(Universidad EAFIT, 2024) Rojas Saldarriaga, Mateo; Sanín Echeverri, Mizrain Edrei; Mazo Barrientos, Juan DanielPublicación Intervención comportamental para incrementar la inscripción a un programa de educación financiera online, en población vulnerable de Nariño, Colombia(Universidad EAFIT, 2024) Kisner Mira, Sandra; Arroyave Duque, María Alejandra; Cardona Tamay, Diana Maritza; Jaramillo Gaviria, Ana MaríaThis study examines efforts to enhance enrollment in a financial education program targeting customers from the Social segment of a financial institution, residing in the department of Nariño, Colombia. The intervention consisted of sending invitation messages via WhatsApp, designed using behavioral techniques such as promoting trust, facilitating action, using simple language, and highlighting benefits, after identifying key behavioral barriers to enrollment. Despite these efforts, the results did not show a significant increase in program enrollment, indicating the need to reconsider the strategies employed. It is recommended to consider the clients' preferred communication channels, personalize invitation messages, and incorporate behavioral variables in audience segmentation. This study contributes to the field of financial education by exploring interventions based on behavioral principles within low-income populations. However, limitations were noted in the availability of demographic data and the capacity to influence certain aspects of intervention design. Further research is recommended to enhance the effectiveness of such programs.Publicación ¿Puede la empatía reducir las percepciones negativas sobre el contrario político? : intervención comportamental tipo nudge para mitigar la deshumanización política en el contexto actual colombiano(Universidad EAFIT, 2024) Orrego López, Mónica María; Trujillo Urrea, Juan PabloPublicación Proyecto Leé : proyecto basado en los estudios del comportamiento para fomentar la lectura recreativa en niñas y niños del barrio Bello Oriente(Universidad EAFIT, 2024) Gómez, Juan Esteban; Jaramillo Arango, Laura; Ospina, Margarita; Cano, Carolina A.This master's thesis in Behavioral Studies from EAFIT University presents a behavioral science-based intervention to promote recreational reading among children in Bello Oriente, Medellín. The central issue is the low reading habit in Colombia, compared to other similarly developed countries. Through this pilot project, we seek to develop activities to increase voluntary and recreational reading. In collaboration with the Waima and Casa Loma foundations, dynamic and pedagogical activities were developed for this community. An interactive diagnosis revealed that children had a positive disposition towards reading but in the practice, they didn’t actually read. The diagnosis was based on the COM-B model by the Behavioral Change Wheel, focusing on functions such as modeling, enablement, and persuasion to promote recreational reading. While the intervention design was based on the MINDSPACE model. In-person sessions included gamification strategies and experiences designed to increase reading engagement. The effectiveness of the intervention was evaluated through individual surveys. Important ethical aspects were considered when working with under-aged subjects, ensuring a safe and respectful environment. Results include an increase in the number of pages read weekly, which contributes to cognitive development and general well-being of the children in Bello Oriente. This approach aims to transform reading into a desirable and accessible activity for all participants, improving their reading skills and quality of life.Publicación Mindspace y ahorro : estrategias comportamentales para el futuro financiero de los jóvenes(Universidad EAFIT, 2024) Gómez Mejía, Hilmer; Echeverri Echeverri, Estefanía; Valencia Aguilar, Mateo; Jaramillo Gaviria, Ana MariaThe objective of the present study was to promote saving behavior among tenth-grade students of an Educational Institution in the Municipality of Copacabana, Antioquia. Through the creation of saving goals and the control of expenses, the aim was to develop greater financial literacy that would enable an increase in saving actions among the students. A quasi-experimental study with pre-test and post-test measurement and a non-probabilistic convenience sample of a single group was conducted. Four presential sessions were held, during which various behavioral techniques based on the components of the MINDSPACE model (Messenger, Incentive, Norm, Default, Salience, Priming, Affect, Commitment, Ego) were addressed. The results showed an increase in students' saving behavior, from 47.8% to 63%. The variable measuring the amount of savings reported a lower overall average in the post-test compared to the pre-test. Additionally, 23.9% experienced a positive change related to expense control. It can be concluded that the behavioral strategies used in the intervention process successfully promoted saving behavior and expense control among the students.Publicación El museo que comparte amigos : intervención conductual EAST (Easy, Attractive, Social, Timely) y su impacto en el comportamiento de revisita al Parque Explora(Universidad EAFIT, 2024) Gaviria Arteaga, Juan Pablo; Cano Torres, Carolina A.Publicación Intervención comportamental para lograr que los líderes de Contento BPS implementen el modelo de felicidad SPIRE en sus equipos(Universidad EAFIT, 2024) Mosquera Moreno, Diego Fernando; Torres Giraldo, Valeria; Torres Cadavid, SusanaAt Contento BPS, a call center based in Itagüí, Antioquia, attempts have been made for 4 years to implement the SPIRE happiness model, a theory that aims to improve employee well-being. However, since the model must be implemented voluntarily, its impact has not been as expected. This project aimed to design a behavioral intervention to encourage the implementation of the SPIRE model in call center leaders, and that, in this way, it could also impact their work teams. According to BCW guidelines and findings. This research was carried out under the following phases: conceptualization that allowed us to know that it was necessary to intervene in reflective motivation, opportunities and capabilities; (2) design of the intervention protocol where the BCTs and functions of the intervention are described; and (3) results that showed good levels of acceptability to the model supported by social support techniques and credible sources as behavioral leveragers. In terms of loyalty, the main event was completed, which was the co-creation workshop and its deliverable was shared with the company, as well as the conceptualization of a communications campaign.
