About this trial

This pilot randomized controlled trial aims to evaluate a Persian-language artificial intelligence (AI)-based cognitive behavioral therapy (CBT) chatbot designed to support adults in managing perceived stress.

A total of 120 adults will be randomly assigned to one of three groups: an AI-based CBT chatbot intervention, active mental health educational content, or a waitlist control. The intervention period will last 14 days. The study will evaluate the feasibility, acceptability, safety, and preliminary effectiveness of the AI-based CBT chatbot for perceived stress management. As a separate research component, voice recordings will be collected from participants at baseline and at the end of the study. These recordings will be used solely as research data to train and evaluate an artificial intelligence model for stress detection. The voice-based model will not be used to guide, modify, personalize, or influence the study intervention, chatbot responses, participant allocation, or clinical decision-making during this trial.

Treatments tested in this trial

  • Persian AI-Based CBT Chatbot

    Behavioral

    A Persian-language artificial intelligence-based conversational intervention designed to provide structured support based on cognitive behavioral therapy principles for adults with mild to moderate perceived stress. The chatbot delivers interactive CBT-based exercises, including psychoeducation, identification and restructuring of maladaptive thoughts, coping strategies, behavioral techniques, and stress-management exercises. The intervention is delivered during a 14-day period and incorporates predefined safety guardrails and crisis-management procedures.

  • Active Mental Health Content

    Behavioral

    Structured, non-adaptive mental health and stress-management educational content provided during the study period. The content is designed to provide general psychoeducation and stress-management support without personalized AI-generated dialogue or adaptive CBT interaction.

Trial outcomes

Primary outcomes

1

Change in Perceived Stress Scale-10 (PSS-10) Score

Change in total Perceived Stress Scale-10 (PSS-10) score from baseline to Day 14. The PSS-10 is used to assess perceived stress, with higher scores indicating greater perceived stress. Changes in PSS-10 scores will be compared across the three study groups.

Time frame
Baseline and Day 14

Secondary outcomes

1

Change in DASS-21 Stress Subscale Score

Change in the DASS-21 Stress subscale score from baseline to Day 14. The stress subscale will be used as a complementary measure of short-term changes in stress across the three study groups.

Time frame
Baseline and Day 14
2

Number of Completed Intervention Sessions

Number of scheduled intervention sessions completed by each participant during the 14-day study period.

Time frame
Throughout the 14-day intervention period
