Development and Field Evaluation of the INTER-ACT App, a Pregnancy and Interpregnancy Coaching App to Reduce Maternal Overweight and Obesity: Mixed Methods Design.

Background: The interpregnancy and pregnancy periods are important windows of opportunity to prevent excessive gestational weight retention. Despite an overwhelming number of existing health apps, validated apps to support a healthy lifestyle between and during pregnancies are lacking.

Objective: To describe the development and evaluation of the INTER-ACT app, which is part of an interpregnancy and pregnancy lifestyle coaching module, to prevent excessive weight gain in pregnancy and enhance optimal weight and a healthy lifestyle in the interpregnancy period.

Designing a Patient Portal for Patient-Centered Care: Cross-Sectional Survey.

Background: In recent literature, patient portals are considered as important tools for the delivery of patient-centered care. To date, it is not clear how patients would conceptualize a patient portal and which health information needs they have when doing so.

Objective: This study aimed (1) to investigate health information needs, expectations, and attitudes toward a patient portal and (2) to assess whether determinants, such as patient characteristics, health literacy, and empowerment status, can predict two different variables, namely the importance people attribute to obtaining health information when using a patient portal and the expectations concerning personal health care when using a patient portal.

Shedding light on an unknown reality in solid organ transplant patients' self-management: A contextual inquiry study.

Traditional quantitative and qualitative research methods inadequately capture the complexity of patients' daily self-management. Contextual inquiry methodology, using home visits, allows a more in-depth understanding of how patients integrate immunosuppressive medication intake, physical activity, and healthy eating in their daily lives, and which difficulties they experience when doing so. This mixed-method study comprised 2 home visits in 19 purposively selected adult heart, lung, liver, and kidney transplant patients, asking them to demonstrate how they implement the aforementioned health behaviors.

Technology Experience of Solid Organ Transplant Patients and Their Overall Willingness to Use Interactive Health Technology.

Background: The use of interactive health technology (IHT) is a promising pathway to tackle self-management problems experienced by many chronically ill patients, including solid organ transplant (Tx) patients. Yet, to ensure that the IHT is accepted and used, a human-centered design process is needed, actively involving end users in all steps of the development process. A first critical, predevelopment step involves understanding end users' characteristics.
