Development of an eHealth Mindfulness-Based Music Therapy Intervention for Adults Undergoing Allogeneic Hematopoietic Stem Cell Transplantation: Qualitative Study

For usability testing, participants completed the 30-item USE questionnaire [65] which contains 4 subscales assessing usefulness (eg, “It helps me be more effective”), ease of use (eg, “It is easy to use”), ease of learning (eg, “I learned to use it quickly”), and satisfaction (eg, “I am satisfied with it”) on an 8-point Likert scale (1=strongly disagree to 8=strongly agree).

A Novel Just-in-Time Intervention for Promoting Safer Drinking Among College Students: App Testing Across 2 Independent Pre-Post Trials

Sample items include “I think that I would like to use bhoos frequently” and “I thought bhoos was easy to use.” Responses to each item range from 1 (strongly disagree) to 5 (strongly agree). Possible scores on the SUS range from 0 to 100, with a higher score indicating higher overall usability of a system or program. The SUS has been used in roughly 3500 surveys within 273 studies evaluating a range of systems, interfaces, and programs [37]. Internal consistency of the SUS was good (α=0.84).

Support of Home-Based Structured Walking Training and Prediction of the 6-Minute Walk Test Distance in Patients With Peripheral Arterial Disease Based on Telehealth Data: Prospective Cohort Study

Treatment for Fontaine stage I is typically limited to risk factor management (eg, nicotine abstention and blood pressure management), which remains a relevant factor throughout all following stages. In Fontaine stage II, medication regimen and structured walking training (SWT) become additional treatment options. While medication is also recommended throughout stages III and IV, SWT is only prescribed in stages II and III.

Development of Digital Strategies for Reducing Sedentary Behavior in a Hybrid Office Environment: Modified Delphi Study

Although applying physical changes such as standing desks may be a solution to break up sitting time at work, it appears to be a less feasible strategy in the home office context due to the expensive cost for the companies: I’m a big advocate of standing desks, standing workstations in terms of being effective but I appreciate that in this situation it’s probably not feasible for them to be incorporated in the home-office.
