Number of participants that the trial has enrolled

927

Results

Providing fertility education using a chatbot improved fertility knowledge and intentions to optimise preconception behaviour without increasing anxiety, but the improvement in knowledge was small. Further technical development and exploration of personal affinity for technology is required.

Baseline Characteristics

Participants were about 29 years old, and more than 60% had a university education, which was higher than the national university enrolment ratio of 43% among female high school graduates in 2008. Less than half were married, and most had no children. Baseline sociodemographic status was well-balanced between groups.

Participant flow

An online market research company, which has a nationwide social research panel of more than 1 million registrants, sent a pre-screening questionnaire regarding the inclusion criteria to 196195 randomly selected female registrants aged 20-34 years. Of the 10000 women who responded to the screening questions, 2524 were eligible. Among the 1,813 who were randomly selected from the eligible respondents and received recruitment emails, 927 completed the survey. Participants were then randomized to one of the three previously described groups using a computerized central allocation system. Participants did not learn of their group assignment until they completed the post-test survey.

Adverse events

No adverse events.

Outcome measures

The percentages of correct scores on the pre-test CFKS-J were similar between groups. A repeated-measures ANOVA of the scores on the CFKS-J showed a significant interaction between group and time. Simple effects of time for each group showed that knowledge improved over time in the IG and CG1. The post-test CFKS-J score for the IG was 7.7 points lower than that of CG1 and 6.7 points higher than that of CG2.
