Online Personalized Intervention for the Prevention of Anxiety.

prevANS intervention will be self-guided and can be implemented from the prevANS web or from the participants' Smartphone (through an APP). The prevANS intervention will have different intensities depending on the risk level of the population, evaluated from the already validated risk algorithm for anxiety: predictA. Participants will be classified as moderate-high or low risk of anxiety. Both groups of risk will receive information on their level and profile (risk factors) of anxiety and psychoeducational information periodically; also, they will work towards manage stressors and enhance protective factors. However, participants with moderate-high risk of anxiety will also receive a cognitive-behavioral training (problem solving, decision-making, handling thoughts / concerns and emotions and communicational skills).
