Promotion of Preconception Care Among Adolescents and Young Adults by Conversational Agent

Preconception care is important for all women to improve infant and maternal health outcomes and may be especially important for adolescents and young adults. This study assesses the acceptance, usability, and use of an automated intervention to screen women on 108 preconception care risks and address them over the course of a year via a Web-based virtual animated health counselor and compares these measures for the adolescent and young adult users aged 18-25 years with those of users aged 26-34 years. We hypothesize that the younger cohort will have significantly greater use of and satisfaction with the online intervention.

A randomized controlled trial involving a national sample of 528 women was conducted. We present a secondary data analysis on the system use and self-reported usability and satisfaction of the 79 women aged 18-25 years randomized to the intervention group, compared with the 183 women aged 26-34 years in the intervention group. Participants were required to self-identify as female, black or African American, aged 18-34 years, not pregnant, and English-speaking and were recruited through a variety of advertisements and outreach activities.

Of the adolescent and young adult participants (aged 18-25 years) enrolled and randomized to the intervention, 20.25% of participants accessed the system 0 times; 29.11%, 1-3 times; and 50.63%, >3 times over the course of a year. At the end of the year, almost all (96.4%) indicated they had either acted on recommendations made by the agent or planned to. Most (75.0%) said they would recommend the system to someone they knew. There were no significant differences between the two age groups on intervention use or satisfaction.

Web-based conversational agents are a viable medium for delivering longitudinal preconception care counseling to adolescents and young adults.
