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. Does an AI-based psychoeducation chatbot improve anxiety-related mental health literacy compared with text-based psychoeducation? 2. Does adding interactive anxiety simulation conversations further improve mental health literacy and related outcomes compared with psychoeducation alone? Researchers will compare participants who use an AI psychoeducation chatbot alone, participants who use an AI psychoeducation chatbot combined with anxiety simulation chatbots, and participants who receive text-based psychoeducation, to see whether the AI-based interventions lead to greater improvements in mental health literacy and related outcomes. Participants will: 1. Complete baseline questionnaires assessing anxiety-related knowledge, attitudes, and symptoms 2. Be randomly assigned to one of three groups: AI psychoeducation chatbot, AI psychoeducation chatbot plus anxiety simulation chatbots, or text-based psychoeducation 3. Use the assigned intervention over a one-week period 4. Complete follow-up questionnaires immediately after the intervention and at later follow-up time points

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 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.
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.

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.
Time frame: 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.
Time frame: pre-intervention, post-intervention (1-week), 4-week follow-up, 12-week follow-up
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.
Time frame: 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.
Time frame: 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.
Time frame: pre-intervention, post-intervention (1-week), 4-week follow-up, 12-week follow-up
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.
