Only a few after our Dagstuhl seminar I met Eric Hekler from the Arizona State University again in the summer heat of Phoenix. I remember that he warned me about the temperatures of Phoenix in August 😉 Anyway – it was very nice to meet him and his PhD students and talk about behavior change, not to talk about the great food! One pressing topic in the field is the understanding of meaningful moments for health. How to understand and detect moments in which we are available and receptive for health related interventions. Looking forward to see further research projects and publications in this field. We are working on our summary of the Dagstuhl report and initiate further events in the field.
