Key Findings

  • 01Chatbots significantly increased total physical activity (SMD = 0.28), daily steps (SMD = 0.28), and moderate-to-vigorous physical activity (MVPA) (SMD = 0.53).
  • 02Chatbot interventions led to improvements in fruit and vegetable consumption (SMD = 0.59), sleep duration (SMD = 0.44), and sleep quality (SMD = 0.50).
  • 03Text-based and AI-powered chatbots were more effective for dietary improvements, while multicomponent interventions were superior for sleep outcomes.
02

Application

Design takeaway

Designers should explore the integration of AI and text-based conversational elements into digital products aimed at promoting healthy lifestyle changes.

How to apply

When designing health and wellness applications, consider incorporating AI-powered chatbots that offer personalized guidance and support for physical activity, nutrition, and sleep.

Project actions

  • 01When designing a digital health tool, consider how a chatbot could provide personalized feedback and motivation.
  • 02Explore how AI can be used to adapt the chatbot's responses based on user input and progress.

Method & Evidence

AimTo evaluate the efficacy of chatbot interventions in improving physical activity, diet, and sleep behaviors.
MethodSystematic Review and Meta-Analysis
ProcedureA comprehensive search of electronic databases was conducted for controlled trials evaluating chatbot interventions targeting physical activity, diet, and/or sleep. Meta-analysis was performed to calculate standardized mean differences for various outcomes, with subgroup analyses exploring the impact of chatbot type, intervention design, and AI integration.
Sample19 trials with participant numbers ranging from 25 to 958.
ContextDigital Health Interventions

Variables

IVChatbot interventions (type, AI integration, multicomponent vs. chatbot-only)
DVPhysical activity levels, steps, MVPA, fruit and vegetable consumption, sleep quality, sleep duration
CVParticipant age, intervention duration, specific health behaviors targeted

Strengths & Limitations

Strengths

  • +Comprehensive systematic review and meta-analysis approach.
  • +Inclusion of a wide range of lifestyle behaviors.

Limitations

The quality of the studies reviewed was often low, meaning the results might not be as strong as they appear. Also, the effectiveness can depend heavily on how the chatbot is designed and who is using it.

Reliability & validity

The meta-analysis provides a robust estimate of the average effect size across multiple studies, increasing reliability. However, the validity is somewhat limited by the reported low quality of many individual trials.

Think critically

Given the low quality of many included studies, how might future research better establish the causal link between chatbot use and sustained behavioral change?
