NCT06920602

Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

  • 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.

    At the end of each 1-month intervention period

  • 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.

    At the end of each 1-month intervention period

  • 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

    At the end of each 1-month intervention period

  • 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.

    At the end of each 1-month intervention period

Interventions

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.

Sequence 1

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.
