About this study

Official title: Development and Evaluation of an AI-empowered Voice-interactive Chatbot for Migraine Management Among Hong Kong Women: a Randomized Crossover Trial

The goal of this randomized crossover trial is to examine whether the AI-empowered chatbot will effectively collect comprehensive migraine feature data and demonstrate higher compliance, accuracy, utilization, acceptability, feasibility, and validity in migraine feature tracking compared to traditional paper-based migraine diaries among Hong Kong women with migraine.

Participants will use different tools (AI-empowered voice-interactive chatbot or paper migraine diary) for migraine tracking. Participants will be randomly allocated to one of two intervention sequences: (1) AI-empowered voice-interactive chatbot followed by paper migraine diary, or (2) paper migraine diary followed by AI-empowered voice-interactive chatbot. The study will consist of two intervention periods, each lasting one month, with a 1:1 allocation ratio.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AI-empowered voice-interactive chatbotDevice

    Participants will interact with the chatbot on a daily basis to record their migraine experiences. They will be asked to initiate a conversation with the chatbot whenever they experience a migraine attack and provide the required information, including the date and time of the attack, presence of aura, migraine intensity, accompanying symptoms, triggers, and medication use. The chatbot will engage participants in a conversation to collect these data points and store them securely within the chatbot system.

  • Paper migraine diaryDevice

    Participants will manually document their migraine experiences on the paper migraine diary, including the date and time of the attack, presence of aura, migraine intensity, accompanying symptoms, triggers, and medication use.

  • Paper migraine diaryDevice

    Participants will manually document their migraine experiences on the paper migraine diary, including the date and time of the attack, presence of aura, migraine intensity, accompanying symptoms, triggers, and medication use.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. timeliness

    Timeliness will be defined as the proportion of migraine episodes recorded within 24 hours of onset. This measure will be derived from the data collected through the chatbot and paper diary.

    Measured: At the end of each 1-month intervention period

  2. Completeness

    Completeness will be defined as the proportion of diary entries with all required migraine-related information fully recorded. This measure will be derived from the data collected through the chatbot and paper diary.

    Measured: At the end of each 1-month intervention period

  3. Missed episodes

    Missed episodes will be defined as the proportion of migraine episodes not recorded; the number of missed episodes in each period will be obtained at the end-of-period questionnaire

    Measured: At the end of each 1-month intervention period

  4. Accuracy

    Accuracy will be defined as the proportion of diary entries in which all required migraine-related fields were recorded correctly. Accuracy will be adjudicated by assessing the consistency between migraine features recorded using the chatbot or paper diary and those reported during end-of-period online interviews with study staff. Discrepancies will be documented; records will be not altered for primary analyses. During these interviews, researchers will summarise the participant's recorded migraine information for that period, regardless of modality, and ask the participant to identify any errors.

    Measured: At the end of each 1-month intervention period

Secondary outcomes (5)
  1. Utilization

    Utilization will be evaluated using the Chinese version of the System Usability Scale (SUS), a widely used and validated 10-item questionnaire that assesses the usability of a system on a 5-point Likert scale. The SUS yields a single score ranging from 0 to 100, with higher scores indicating better usability. Specifically, chatbot utilization will be objectively assessed using system-generated data, such as the number of logins, user-initiated conversations, and user responses.

    Measured: At the end of each 1-month intervention period

  2. Acceptability

    Acceptability will be measured using the validated Chinese version of Technology Acceptance Model (TAM) scale, an 11-item questionnaire on a 7-point Likert scale with higher scores indicating greater acceptance.

    Measured: At the end of each 1-month intervention period

  3. Usage

    Usage will be assessed by the number of uses (entries) per tool.

    Measured: At the end of each 1-month intervention period

  4. Time per recording

    Time required to record each migraine episode, using system-logged durations for the chatbot and self-recorded start and finish times for the paper diary.

    Measured: At the end of each 1-month intervention period

  5. Validity

    The validity of the migraine data collected through the chatbot and paper diary will be assessed using convergent validity and divergent validity. Convergent validity will be evaluated by examining the correlation between migraine frequency and severity recorded using the chatbot or paper diary and the Chinese version of the Migraine Disability Assessment (MIDAS) scores (0 to 270, higher scores indicating greater migraine-related disability). Divergent validity will be assessed by analyzing the correlation between migraine frequency and severity and the Chinese version of the Brief Self-Control Scale (7 to 35, with a higher score indicating greater self-control).

    Measured: At the end of each 1-month intervention period

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

timeliness (time frame: At the end of each 1-month intervention period). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Dec 2025.
