Participants are only required to self-monitor their sleep patterns and join a chatbot group for contact.

An in-person, nurse-led Brief Behavioral Treatment for Insomnia (BBT-I) intervention, supplemented by an chatbot that provides educational content and remote, two-way interactive support.

Daily self-recording of sleep behaviors during the intervention. Such as time in/out of bed, napping, and subjective sleep quality along with lifestyle factors like screen time, diet, and exercise, helps researchers understand subjects' actual sleep patterns and health behaviors.

The Insomnia Severity Scale (ISI) is a 7-item self-report scale for insomnia symptoms. Participants self-report their difficulty falling asleep, difficulty maintaining sleep, early awakening, and the severity of these symptoms' impact on daily life. Each item on the ISI is scored on a 5-point Likert scale (0-4 points), with the total score ranging from 0 to 28 points. Higher score indicates more severe insomnia.

Pittsburgh Sleep Quality Scale (PSQI) was utilized to assess the level of sleep disturbances for adults. The PSQI is a 19-item self-administered questionnaire scored on a Likert scale from 0 to 3. Higher score indicates greater sleep disturbances.

The Patient Health Questionnaire 9-item (PHQ-9) scale contains 7 items to assess the level of depression over the past two weeks. Each item is rated on a 4-point Likert scale, ranging from 0 (never) to 3 (almost every day). The scale score range is 0 to 27. Higher score indicates more severe depression level.

Based on the six dimensions of the Healthcare Information System (HIS) success model proposed by DeLone and McLean (2003), a questionnaire was designed to assess the intervention group's satisfaction with and acceptance of the education chatbot. This self-administered tool utilized a 5-point Likert scale (ranging from 1 to 5), where higher scores indicate greater acceptance and satisfaction.
