AI Chatbots for Anxiety Mental Health Literacy

NCT07316374 | Active Not Recruiting

• 1 other identifier: Anxiety Literacy AI Chatbot
• Study Type: interventional
• Target: 200

Brief Summary

The goal of this clinical trial is to examine whether AI-based chatbots can improve anxiety-related mental health literacy in adults with varying levels of anxiety. The study aims to learn whether interactive AI chatbots can improve understanding of anxiety, attitudes toward anxiety, help-seeking intentions, confidence in supporting others, and anxiety symptoms, compared with standard text-based educational materials. The main questions it aims to answer are:

1. 1.Does an AI-based psychoeducation chatbot improve anxiety-related mental health literacy compared with text-based psychoeducation?
2. 2.Does adding interactive anxiety simulation conversations further improve mental health literacy and related outcomes compared with psychoeducation alone?
3. 3.Complete baseline questionnaires assessing anxiety-related knowledge, attitudes, and symptoms
4. 4.Be randomly assigned to one of three groups: AI psychoeducation chatbot, AI psychoeducation chatbot plus anxiety simulation chatbots, or text-based psychoeducation
5. 5.Use the assigned intervention over a one-week period
6. 6.Complete follow-up questionnaires immediately after the intervention and at later follow-up time points

Outcome Measures

Primary Outcomes (6)

• Anxiety Literacy Scale (ALS)

  The Anxiety Literacy Scale is a 22-item questionnaire designed to assess individuals' knowledge about anxiety. Each statement is answered using a binary response format (true or false). For each item, participants are also asked to rate their certainty in their response on a 5-point Likert scale. Correct responses are summed to produce a total knowledge score, with higher scores indicating greater anxiety-related mental health literacy. Certainty ratings are used to assess participants' confidence in their knowledge and to examine the calibration between knowledge accuracy and subjective certainty.

  pre-intervention, post-intervention (1-week), 4-week follow-up, 12-week follow-up

• Anxiety Stigma Scale

  The Anxiety Stigma Scale is designed to measure stigma associated with Anxiety. It has two subscales which measure two different types of stigma: personal and perceived. The Personal Stigma Subscale measures stigma in the respondents own attitudes towards anxiety by asking them to indicate how strongly they personally agree with ten statements about anxiety. The Perceived Stigma Subscale measures the respondent's perception about the attitudes of others towards anxiety by asking them to indicate what they think most other people believe about the same ten statements. Responses to each item are measured on a five-point scale (ranging from zero 'strongly disagree' to four 'strongly agree'). Higher scores indicate higher levels of depression stigma.

• Adapted General Help-Seeking Questionnaire

  The General Help-Seeking Questionnaire (GHSQ) in this study is an adapted 17-item version designed to fit Chinese cultural contexts. It assesses an individual's intentions to seek help for personal or emotional problems from both formal sources (e.g., mental health professionals, doctors) and informal sources (e.g., family, friends). Each item is rated on a 7-point Likert scale, ranging from 1 ("Extremely Unlikely") to 7 ("Extremely Likely"), with higher scores indicating a greater likelihood of seeking help.

  pre-intervention, post-intervention (1-week), 4-week follow-up, 12-week follow-up

• Confidence in Helping Others

  The Confidence in Helping Others Scale is a self-developed, 13-item questionnaire designed to measure participants' confidence in providing support to individuals experiencing mental health issues. Each item is rated on a 5-point Likert scale, ranging from 1 ("Strongly Disagree") to 5 ("Strongly Agree"), with higher scores indicating greater confidence in recognizing symptoms, offering emotional support, and encouraging help-seeking.

  pre-intervention, post-intervention (1-week), 4-week follow-up, 12-week follow-up

• Mental Health Self-efficacy Scale

  The Mental Health Self-efficacy Scale is a 6-item questionnaire designed to measure participants' confidence in effectively manage stress, anxiety or depression about themself. Each item is rated on a 10-point Likert scale, ranging from 1 ("Not at all confident") to 10 ("Totally confident"), with higher scores indicating greater confidence in self-efficacy about mental health.

• Bot Usability Scale

  The Bot Usability Scale (BUS) in this study is an adapted 11-item version designed to assess the usability of AI-based chatbots. It evaluates participants' perceptions of the ease of use, effectiveness, efficiency, and overall user experience of the chatbots. The scale uses a 5-point Likert scale, ranging from 1 ("Strongly Disagree") to 5 ("Strongly Agree"), with higher scores indicating better perceived usability. Participants will complete the adapted BUS separately for both the AI Educator and the AI Anxiety Friend Simulators. The adapted BUS maintains the core usability assessment principles of the original scale while being tailored for AI-driven conversational agents.

Study Arms (3)

AI Educator Only

EXPERIMENTAL

Participants will interact with the AI-powered psychoeducation chatbot for one week. The chatbot delivers structured conversational modules covering anxiety concepts, symptoms, causes, treatment options, and self-help strategies.

Behavioral: AI Anxiety Literacy Education

AI Educator + AI Anxiety Friend Simulators

EXPERIMENTAL

Participants will first complete all AI Educator modules and then interact with five AI Anxiety Friend Simulators over one week. Each simulator represents a distinct anxiety presentation and prompts participants to identify symptoms, explore mechanisms, and propose support strategies.

Behavioral: AI Anxiety Literacy Education; Behavioral: AI Anxiety Friend Simulation

Text-Based Psychoeducation

ACTIVE COMPARATOR

Participants will receive standard text-based psychoeducation materials about anxiety, including definitions, symptoms, causes, and coping strategies, to be completed within one week.

Behavioral: Text-Based Anxiety Psychoeducation

Interventions

AI Anxiety Literacy Education BEHAVIORAL

AI Anxiety Literacy Education is an AI-powered, psychologically informed chatbot designed to improve mental health literacy related to anxiety through conversational education. The chatbot delivers structured modules covering the definition of anxiety, common cognitive, emotional, physical, and behavioral symptoms, contributing factors, treatment options, and practical self-help strategies. Content is presented in non-clinical language and adapted to user responses through guided questions and feedback, encouraging users to reflect on their own experiences.

AI Educator + AI Anxiety Friend Simulators; AI Educator Only

AI Anxiety Friend Simulation BEHAVIORAL

AI Anxiety Friend Simulation is an AI-powered conversational intervention designed to allow participants to practice recognizing and responding to anxiety-related experiences in a simulated interaction. The chatbot role-plays individuals experiencing different anxiety presentations and communicates in a natural, everyday manner that may include uncertainty, emotional reactions, or defensiveness. Participants are guided to identify anxiety symptoms, explore causes, and propose supportive responses. The chatbot provides feedback and prompts reflection based on participants' responses. Participants access the simulation online and complete multiple simulated conversations over a one-week period.

AI Educator + AI Anxiety Friend Simulators

Text-Based Anxiety Psychoeducation BEHAVIORAL

Text-Based Anxiety Psychoeducation consists of written educational materials providing information about anxiety in a non-clinical, accessible format. The materials cover the definition of anxiety, common cognitive, emotional, physical, and behavioral symptoms, contributing factors, and general coping and self-help strategies. Participants access the materials online and are instructed to review all content within a one-week period. The materials are static and do not provide interactive feedback or personalized responses.
