A Mindfulness-Based App Intervention for Pregnant Women: Qualitative Evaluation of a Prototype Using Multiple Case Studies

A Mindfulness-Based App Intervention for Pregnant Women: Qualitative Evaluation of a Prototype Using Multiple Case Studies

Participants were recruited through instant messaging tools (Whats App [Meta]) and email. In the first iteration, psychologists, mindfulness, and communication experts tested and gave feedback on the prototype to ensure that the intervention program was logically built. Participants were given oral and written information about the study and provided written informed consent before user testing. At this stage, the Personas methodology was also found useful.

Effect of Personalized Email-Based Reminders on Participants’ Timeliness in an Online Education Program: Randomized Controlled Trial

In another social comparison study, MOOC students were divided into three groups: the first group received a positively formulated email (you did better than n% of students), the second group received a negatively formulated email (you did worse than n% of students), and the third group served as a control and did not receive any emails. Both test groups improved their test scores by 8% compared to the control group.

Testing Behavior Change Techniques to Increase Physical Activity in Middle-Aged and Older Adults: Protocol for a Randomized Personalized Trial Series

They will provide feedback on key aspects of study design, including BCT choices, BCT descriptions, materials, and electronic delivery methods such as SMS text messaging and email receipt. Up to 10 of the 60 participants will engage with study materials and procedures as “mock participants,” interacting remotely and providing feedback about the ease and acceptability of study procedures to further refine study materials and procedures.

An Economic Impact Model for Estimating the Value to Health Systems of a Digital Intervention for Diabetes Primary Care: Development and Usefulness Study

An Economic Impact Model for Estimating the Value to Health Systems of a Digital Intervention for Diabetes Primary Care: Development and Usefulness Study

Eligible patients receive 1 email per week for 5 weeks, followed by an 8-week pause, and then another 1 message per week for 5 weeks. This pattern repeats until the patient either unsubscribes from the intervention or takes action by scheduling and attending a PCP visit. The key outcome metric associated with Precision Nudging is the completion of a primary care appointment. The outcome of appointment attendance serves as the basis for the economic model.
