Self-selection and attrition biases in app-based persuasive technologies for mobility behavior change: Evidence from a Swiss case study
作者：
Highlights：
• App-based persuasive technologies for behavior change are increasingly exploited to promote sustainable mobility.
• Self-selection and attrition due to the opt-in framework may affect their actual impact and bias the estimate of this impact.
• We analyze mobility data collected in an app-based behavior change intervention run in Southern Switzerland.
• Comparison with census data on mobility and analysis of app use over time show no evidence of critical biases.
• Further research is worth analyzing the app's actual impact and the reasons for the observed high drop-out rate.
