The Effect of a Mobile App (eMOM) on Self-Discovery and Psychological Factors in Persons With Gestational Diabetes: Mixed Methods Study

The Effect of a Mobile App (eMOM) on Self-Discovery and Psychological Factors in Persons With Gestational Diabetes: Mixed Methods Study

Finally, we will evaluate the acceptance and usability of the e MOM app. This study is a secondary analysis of e MOM GDM RCT [20], where the intervention arm used the e MOM app with a CGM and activity bracelet for 1 week per month and a digital food diary for 3 days of this week (referred to as the ‘app week’ later in this paper), from gestational weeks 24-28 to delivery. The e MOM GDM study was conducted between February 2021 and December 2022 in Helsinki, Finland.

Extended Reality Biofeedback for Functional Upper Limb Weakness: Mixed Methods Usability Evaluation

Extended Reality Biofeedback for Functional Upper Limb Weakness: Mixed Methods Usability Evaluation

After completing all 3 tasks, participants filled out the system usability scale (SUS) questionnaire for each task. The SUS is a 10-item questionnaire yielding a score from 0 to 100, where higher scores indicate better perceived usability. We chose the SUS because it is a well-established, quick tool for usability assessment, suitable even for small samples [26]. Participants also provided written free-text feedback on their experience with each task and the overall platform.

Usability Evaluation of an Electrically Powered Orthopedic Exerciser: Focus Group Interview and Satisfaction Survey Study

Usability Evaluation of an Electrically Powered Orthopedic Exerciser: Focus Group Interview and Satisfaction Survey Study

Usability issues in medical devices can directly affect patient safety and treatment outcomes, often arising from deficiencies in UI design [12]. To mitigate such risks, the International Electrotechnical Commission (IEC) introduced the IEC 62366 standard, which emphasizes the integration of usability engineering throughout the device development process, distinguishing between formative and summative evaluations [13-15].

Co-Designed Digital Device for Tracking Rehabilitation Dosage in a Clinical Environment After Stroke: Mixed Methods Validity and Feasibility Study

Co-Designed Digital Device for Tracking Rehabilitation Dosage in a Clinical Environment After Stroke: Mixed Methods Validity and Feasibility Study

This pilot study, conducted in 2 phases, evaluated the digital dose tracker, co-designed by users, by assessing its feasibility, validity, and usability. Phase 1 focused on a usability study (n=9) conducted in a research setting. Phase 2 involved a clinical trial to assess the trackers’ feasibility and validity (n=15). The primary outcome for Phase 1 was usability, measured by the System Usability Scale (SUS) and Intrinsic Motivation Inventory (IMI).

Evaluating the Usability, Acceptability, User Experience, and Design of an Interactive Responsive Platform to Improve Perinatal Nurses’ Stigmatizing Attitudes Toward Substance Use in Pregnancy: Mixed Methods Study

Evaluating the Usability, Acceptability, User Experience, and Design of an Interactive Responsive Platform to Improve Perinatal Nurses’ Stigmatizing Attitudes Toward Substance Use in Pregnancy: Mixed Methods Study

Before evaluating the effectiveness of a digital adaptation, it is critical to examine its use and sustainability [48,49], including usability, acceptability, and feasibility with end users. Usability is characterized by how well specific users achieve a predetermined goal with efficiency and satisfaction in a particular context [50]. Acceptability relates to how end users think and feel about a digital intervention, while feasibility relates to how well it can be deployed with end users [51-53].

Optimizing Clinical Decision Support System Functionality by Leveraging Specific Human-Computer Interaction Elements: Insights From a Systematic Review

Optimizing Clinical Decision Support System Functionality by Leveraging Specific Human-Computer Interaction Elements: Insights From a Systematic Review

In this regard, related concepts, such as usability, UX, or user-centered design (UCD), all of which contribute to physician satisfaction, need to be investigated. HCI assists in identifying system requirements, including text style, fonts, layout, graphics, and color. Meanwhile, usability focuses on efficiency, effectiveness, utility, ease of learning, and ease of assessment.

Translation, Cross-Cultural Adaptation, and Psychometric Validation of the Health Information Technology Usability Evaluation Scale in China: Instrument Validation Study

Translation, Cross-Cultural Adaptation, and Psychometric Validation of the Health Information Technology Usability Evaluation Scale in China: Instrument Validation Study

In contrast, usability, defined as the extent to which users can use an app to achieve specific objectives with efficiency, satisfaction, and effectiveness in a specified usage context, is crucial to reflect the quality and efficacy of digital health apps [8,9]. Therefore, a rigorous and validated usability evaluation tool is urgently warranted to produce objective usability results for digital health apps before their release.
