MentalRiskES2026 announces the fourth edition of a novel and enhanced task on early risk identification of mental disorders in Spanish comments from social media sources. Unlike previous editions (IberLEF 2023, 2024, and 2025), this edition introduces significant innovations: psychologists are now actively involved in generating and validating the data, which ensures a closer connection to real clinical settings. The task continues to be solved as an online problem, requiring participants to detect potential risks as early as possible in a continuous stream of data. Consequently, performance depends not only on the accuracy of the systems but also on the speed of detection, reflecting these dynamics in both task design and evaluation metrics.

For this fourth edition, we propose two entirely new tasks: the first subtask focuses on the detection of symptoms, while the second subtask addresses decision support for therapeutic interventions.

We would like to invite you to participate in the following tasks:

*1. Early Symptom Detection in Therapeutic Conversations2. Therapist Response Selection*
