DUDIT-E Brazilian Adaptation and TrIE-AD Application Development: A Intervention Approach for Young Drug Users

Introduction: This study comprises two distinct phases, focusing on the adaptation of an assessment instrument and the development of a digital tool to address issues related to drug use among adolescents and young adults in Brazil.

Objectives: The aim of the first phase was to adapt the Drug Use Disorders Identification Test - Extended (DUDIT-E) for this public, providing a tool for health professionals to use in assessing the frequency and other aspects related to drug use. Simultaneously, the second phase aimed to describe the development of the TrIE-AD application, integrating the adapted DUDIT-E, intervention protocols, educational resources, and a training course for health professionals. Methods: In the first phase, the DUDIT-E was translated and adapted into digital format for use with Brazilian adolescents and young adults. Focus groups were held with 10 adolescents, resulting in adjustments to improve young people's understanding and identification of the concepts. The adapted version involved expansion to include new classes of substances, the establishment of a 12-month reference period, and linguistic adjustments. In the second study, the TrIE-AD application, based on the cognitive-behavioral model (FRAMES), was developed, going through stages that included authentication for health professionals, screening with 60 questions about substance use in the last 12 months, and sections addressing positive and negative aspects, thoughts, and motivations for treatment.

Results: Results specific to substance use indicated that alcohol was the most prevalent substance, consumed by 58.2% between two and four times a month. Marijuana was the second most used substance, with a use rate of 61.2% in the last 12 months. In the second study, the TrIE-AD app was tested through a pilot application with 26 young people in various contexts, such as universities and specialized treatment services. The application took an average of 30 to 60 minutes and was positively received by young people, highlighting its ease of use, attractive design, and contributions to harm reduction.

Conclusion: Despite some reports of limited access to technology, the app proved to be adaptable and reliable for professionals. The results suggest the feasibility of implementing the digital resource in the processes of early identification, intervention by professionals, and users. These initial results indicate the relevance of innovative approaches to dealing with substance use issues among young people, promoting more effective mental health interventions.
