Online Personalized Intervention for the Prevention of Anxiety. (prevANS)

November 29, 2023 updated by: Patricia Moreno Peral, University of Malaga

Effectiveness of an Online Personalized Intervention Based on a Risk Algorithm for the Universal Prevention of Anxiety: Randomized Controlled Trial. The prevANS Study.

Objective: To design, develop and evaluate an online personalized intervention based on a risk algorithm for the universal prevention of anxiety disorders in the general population.

Methods: Randomized controlled trial, with two parallel arms and 12 months follow-up. The entire process of recruitment, randomization, intervention and follow-up will be carried out from a web platform designed for the study (web prevANS). Through a communication campaign, where announcements and informative videos will be produced, and through the dissemination on prevANS website, 2,000 Spanish and Portuguese adult participants without anxiety in the baseline of the study will be recruited. The participants will be randomly assigned to the prevANS intervention, which will be self-guided and can be implemented from the prevANS web or from the participants' Smartphone (through an APP), or to a control group. 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 with a low risk of anxiety will receive information on their level and profile (risk factors) of anxiety and psychoeducational information periodically. Participants with moderate and high risk of anxiety will also receive information on their risk level and profile, but will also include a cognitive-behavioral training (problem solving, decision-making, handling thoughts / concerns and emotions and communicational skills). Both groups of risk will work towards manage stressors and enhance protective factors. The control group will not receive any intervention, but they will fill out the same questionnaires as in the intervention group. The main result will be the incidence of new cases of anxiety disorders measured by CIDI, and the secondary results will be the reduction of anxiety (GAD-7) and depression (PHQ-9) symptoms, of the risk probability of anxiety and depression (predictA and predictD algorithms) and improvement of quality of life measured by SF-12 and EuroQol, and cost-effectiveness and cost-utility.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: prevANS intervention
In this arm, participants will receive an online personalized intervention to prevent anxiety disorders based on a risk predictive algorithm (predictA).
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).
No Intervention: Control group
In this arm, participants will continue receiving the usual care from their health providers. However, they will not receive any intervention, but they will fill out the same questionnaires as in the intervention group.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Primary Outcome Measure
Time Frame: 12 months
Rate of anxiety disorders measured by the Composite International Diagnostic Interview (CIDI). CIDI is a structured diagnostic interview that provides current diagnoses of anxiety disorders according to DSM.
12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Anxious symptoms measured by the General Anxiety Questionnaire (GAD-7)
Time Frame: 12 months
The General Anxiety Questionnaire (GAD-7) measures generalized anxiety disorder through 7 items, each of which is scored 0 ('not at all') to 3 ('nearly every day'). Low scores are equivalent to less symptoms of anxiety, the scale range is 0 to 21 (7 items).
12 months
Depressive symptoms measured by the Patient Health Questionnaire-9 (PHQ-9)
Time Frame: 12 months
The Patient Health Questionnaire-9 (PHQ-9) measures symptoms of depression through 9 items, each of which is scored 0 ('not at all') to 3 ('nearly every day'). Low scores are equivalent to less symptoms of depression, the scalen range is 0 to 27 (9 items).
12 months
Probability of anxiety measured by the Spanish predictA risk algorithm
Time Frame: 12 months
The Spanish predictA risk algorithm measures 12 risk factors for anxiety disorders
12 months
Probability of depression measured by the Spanish predictD risk algorithm
Time Frame: 12 months
The Spanish predictD risk algorithm measures 13 risk factors for depression
12 months
Quality of life measured by SF-12
Time Frame: 12 months
The 12-item Short Form (SF-12) measures quality of life related to physical health and quality of life related to mental health. Scores on the scales range from 0 to 100. Higher scores are equivalent to better health-related quality of life.
12 months
Cost-effectiveness
Time Frame: 12 months
It will be conducted from two perspectives: (1) a societal perspective and (2) a National Health System perspective. We will calculate incremental cost-effectiveness ratio (ICER) using the incremental cost (difference in costs between arms) divided by incremental effectiveness (difference in the number of diagnoses of anxiety disorders between arms).
12 months
Cost-utility
Time Frame: 12 months
It will be conducted from two perspectives: (1) a societal perspective and (2) a National Health System perspective. We will calculate incremental cost-effectiveness ratio (ICER) using the incremental cost (difference in costs between arms) divided by incremental QALYs (difference in QALYs between arms). Quality-adjusted life years (QALYs) will be measured using the EuroQol five questionnaire (EuroQol-5D).
12 months
Acceptability and satisfaction with the intervention (prevANS intervention) measured by u-MARS scale
Time Frame: 12 months
The User Version of the Mobile Application Rating Scale (u-MARS) consists of 23 items assessing app quality, each of which is scored 1 ('poor') to 5('excellent'), except items 14-17 and item 19, which also include the "not applicable" option. Higher scores are equivalent to higher app quality.
12 months
Mediator of the intervention: cognitive change
Time Frame: 12 months
The cognitive change will be evaluated through the number of negative thoughts worked and modified in the app
12 months
Subgroup analysis according to age
Time Frame: 12 months
A subgroup analysis will be conducted according to age of the participants (from 18 to 30 years; from 31 to 50 years; and > 50 years)

Time Frame: 12 months
The General Anxiety Questionnaire (GAD-7) measures generalized anxiety disorder through 7 items, each of which is scored 0 ('not at all') to 3 ('nearly every day'). Low scores are equivalent to less symptoms of anxiety, the scale range is 0 to 21 (7 items). The subgroups will be: 1) from 0 to 5 points; and 2) > 5 points
12 months
Subgroup analysis according to depressive symptoms at baseline (through the PHQ-9 questionnaire)
