Background
Artificial intelligence (AI) is increasingly being used in healthcare. Here,
AI-based chatbot systems can act as automated conversational agents, capable
of promoting health, providing education, and potentially prompting
behaviour change. Exploring the motivation to use health chatbots is
required to predict uptake; however, few studies to date have explored their
acceptability. This research aimed to explore participants’ willingness to
engage with AI-led health chatbots.
Methods
The study incorporated semi-structured interviews (N-29) which informed the
development of an online survey (N-216) advertised via social media.
Interviews were recorded, transcribed verbatim and analysed thematically. A
survey of 24 items explored demographic and attitudinal variables, including
acceptability and perceived utility. The quantitative data were analysed
using binary regressions with a single categorical predictor.
Results
Three broad themes: ‘Understanding of chatbots’, ‘AI hesitancy’ and
‘Motivations for health chatbots’ were identified, outlining concerns about
accuracy, cyber-security, and the inability of AI-led services to empathise.
The survey showed moderate acceptability (67%), correlated negatively with
perceived poorer IT skills OR = 0.32 [CI
95%
:0.13–0.78] and
dislike for talking to computers OR = 0.77 [CI
95%
:0.60–0.99] as
well as positively correlated with perceived utility OR = 5.10
[CI
95%
:3.08–8.43], positive attitude OR = 2.71
[CI
95%
:1.77–4.16] and perceived trustworthiness OR = 1.92
[CI
95%
:1.13–3.25].
Conclusion
Most internet users would be receptive to using health chatbots, although
hesitancy regarding this technology is likely to compromise engagement.
Intervention designers focusing on AI-led health chatbots need to employ
user-centred and theory-based approaches addressing patients’ concerns and
optimising user experience in order to achieve the best uptake and
utilisation. Patients’ perspectives, motivation and capabilities need to be
taken into account when developing and assessing the effectiveness of health
chatbots.
