User Perception of Hydrated Website Prototype for Dehydration Prevention: Quantitative Descriptive Study

Background: Body fluid balance or hydration status is often considered unimportant, but scientific facts show that a lack of fluids, even just one per cent, impacts cognitive decline. So, technology-based efforts are needed, such as an easily accessible website to monitor hydration status and maintain good hydration for the community. This research has described the public's perception of a hydrated website prototype for dehydration prevention Method: This research design is quantitatively descriptive, with a population of 114 respondents, using a purposive random sampling technique. The research variables, namely User perceptions of the Hydrated Website Prototype, include user skills, ease of access, appearance design, completeness of content, and application benefits. The instrument uses a questionnaire that refers to variables/sub-variables, and data analysis is done using a frequency distribution table. Result: Public perception in the good category is 99.1%, including the perception of website prototype users being hydrated to prevent dehydration based on the level of user proficiency in using a smartphone or laptop with the advanced or able-to-use category of 77.2%, ease of access in use with the easy category of 59, 6%, the appearance of the design and completeness of the contents of the website prototype in the exciting category each amounted to 64%. Meanwhile, regarding usability, the hydrated website prototype was very useful at 59.6%. Conclusion: This research concludes that user perceptions of the hydrated website prototype for dehydration prevention are good and accepted by the public.

Optimal Academic Plan Derived from Articulation Agreements: A Preliminary Experiment on Human-Generated and (Hypothetical) Algorithm-Generated Academic Plans

ABSTRACT Our preliminary experiment examined a potential pain point with ASSIST, California’s database of articulation agreements. That pain point is cross-referencing multiple articulation agreements to manually develop an optimal academic plan. Optimal is defined as the minimal set of community college courses that satisfy all transfer requirements for the multiple universities a student is preparing to apply to. Accordingly, we designed a low-fidelity prototype that lists the minimal set of courses a hypothetical optimization algorithm would output based on selected articulation agreements. Twenty-four students were tasked with creating an optimal academic plan using either ASSIST (which requires manual optimization) or the optimization prototype (which already provides the minimal set of classes). Prototype users had less optimality mistakes, were faster, and provided higher usability ratings compared to ASSIST users. Going forward, future research needs to move beyond our proof of value of a hypothetical optimization algorithm and toward actually implementing an algorithm.

APPROACH e-PROM system: a user-centered development and evaluation of an electronic patient-reported outcomes measurement system for management of coronary artery disease

BackgroundCoronary artery disease (CAD) confers increased risks of premature mortality, non-fatal morbidity, and significant impairment in functional status and health-related quality of life. Routine administration of electronic patient-reported outcome measures (PROMs) and its real time delivery to care providers is known to have the potential to inform routine cardiac care and to improve quality of care and patient outcomes. This study describes a user-centered development and evaluation of the Alberta Provincial Project for Outcomes Assessment (APPROACH) electronic Patient Reported Outcomes Measurement (e-PROM) system. This e-PROM system is an electronic system for the administration of PROMs to patients with CAD and the delivery of the summarized information to their care providers to facilitate patient-physician communication and shared decision-making. This electronic platform was designed to be accessible via web-based and hand-held devices. Heuristic and user acceptance evaluation were conducted with patients and attending care providers.ResultsThe APPROACH e-PROM system was co-developed with patients and care providers, research investigators, informaticians and information technology experts. Five PROMs were selected for inclusion in the online platform after consultations with patient partners, care providers, and PROMs experts: the Seattle Angina Questionnaire, Patient Health Questionnaire, EuroQOL, and Medical Outcomes Study Social Support Survey, and Self-Care of Coronary Heart Disease Inventory. The heuristic evaluation was completed by four design experts who examined the usability of the prototype interfaces. User acceptance testing was completed with 13 patients and 10 cardiologists who evaluated prototype user interfaces of the e-PROM system.ConclusionBoth patients and physicians found the APPROACH e-PROM system to be easy to use, understandable, and acceptable. The APPROACH e-PROM system provides a user-informed electronic platform designed to incorporate PROMs into the delivery of individualized cardiac care for persons with CAD.

Tracking Census Online Self-Completion Using Twitter Posts

From the start of data collection for the 2020 US Census, official and celebrity users tweeted about the importance of everyone being counted in the Census and urged followers to complete the questionnaire (so-called social media campaign.) At the same time, social media posts expressing skepticism about the Census became increasingly common. This study distinguishes between different prototypical Twitter user groups and investigates their possible impact on (online) self-completion rate for the 2020 Census, according to Census Bureau data. Using a network analysis method, Community Detection, and a clustering algorithm, Latent Dirichlet Allocation (LDA), three prototypical user groups were identified: “Official Government Agency,” “Census Advocate,” and “Census Skeptic.” The prototypical Census Skeptic user was motivated by events about which an influential person had tweeted (e.g., “Republicans in Congress signal Census cannot take extra time to count”). This group became the largest one over the study period. The prototypical Census Advocate was motivated more by official tweets and was more active than the prototypical Census Skeptic. The Official Government Agency user group was the smallest of the three, but their messages—primarily promoting completion of the Census—seemed to have been amplified by Census Advocate, especially celebrities and politicians. We found that the daily size of the Census Advocate user group—but not the other two—predicted the 2020 Census online self-completion rate within five days after a tweet was posted. This finding suggests that the Census social media campaign was successful in promoting completion, apparently due to the help of Census Advocate users who encouraged people to fill out the Census and amplified official tweets. This finding demonstrates that a social media campaign can positively affect public behavior regarding an essential national project like the Decennial Census.

외국인 유학생을 대상으로 한 앱 디자인 개발 제안

The purpose of this study is to propose a financial lifestyle app that can help both managing financial works and experiencing affordable places to eat and enjoy with consideration of users’ financial status for foreign students who feel difficulty of language barrier and financial difficulties. First, as a consequence of case analysis of related apps for foreigners in Korea, it was found that a number of services specialized for foreigners were provided, but there was no app specifically focusing on the whole process of foreign students’ life of studying in Korea. After conducting an in-depth interview, we were able to derive seven key requirements by making and classifying them with an Affinity Diagram. Based on the seven key requirements, a Persona and Scenario and User Journey Map were produced to confirm and list the requirements of each aspect. Based on this, ‘Cashjoy’ financial lifestyle app concept that is fun and easy to use was created and concludes with prototyping user interfaces of the app, looking forward to further research in the future with higher fidelity of protytype and turning it into a real service.

Penerapan Desain UI/UX dalam Pengembangan Aplikasi Administrasi Keuangan Logistik untuk Efisiensi Operasional di PT Prima Cipta Express dengan Metode Design Thinking

In the current digital era, information technology and software applications are important for increasing operational efficiency in the business world, especially in the fields of logistics and financial management. Ineffective management of logistics financial administration can result in increased costs, delays in delivery, and even inaccuracies in financial reports. Therefore, this research was conducted with the aim of overcoming operational efficiency challenges for PT Prima Cipta Express. One approach that can be taken to overcome this challenge is to apply the Design Thinking method which includes the Empathize, Define, Ideate, Prototype and Test stages. At the testing stage, this research uses usability testing and SUS (System Usability Scale) calculations which are useful for testing prototype usability. This research, testing involved a prototype user experience using Task Scenario. Usability test results according to the System Usability Scale (SUS) calculations reached 86, which is at a good level (grade B) and is included in the "Excellent" category. These results indicate that users positively evaluate the ease of use of the application. Referring to the average SUS score of 68, it can be concluded that this application design is well received by users and is suitable for use.

USER REQUIREMENT FOR WEB-BASED PROCEEDINGS REPOSITORY

Conference is a popular platform for academics to exchange knowledge and engage with one another. The conferences typically produce collections of papers, known as conference proceedings, which are often published online as open-access resources to facilitate more comprehensive access and dissemination of knowledge. Consequently, there has been a significant increase in articles on online conference proceedings. However, the absence of an organised management system has made it increasingly challenging for users to locate and retrieve specific proceedings. To address this issue, this study proposes implementing a digital repository system to simplify the sharing and distributing of conference proceedings articles. The primary goal of this project is to provide a sustainable solution for storing and accessing conference proceedings, characterised by its reliability, efficiency, effectiveness, and user-friendliness. Such an enhancement is anticipated to boost research productivity and quality. In this article, we present the system requirements for the repository. Subsequently, based on these requirements, we have developed a prototype called the Web-based Digital Repository for Proceedings Articles (WDR). We conducted a field study to assess the prototype's usability, and the evaluation results indicate that WDR is both practical and user-friendly.

A dynamic approach for visualizing and exploring concept hierarchies from textbooks.

In this study, we propose a visualization technique to explore and visualize concept hierarchies generated from a textbook in the legal domain. Through a human-centered design process, we developed a tool that allows users to effectively navigate through and explore complex hierarchical concepts in three kinds of traversal techniques: top-down, middle-out, and bottom-up. Our concept hierarchies offer an overview over a given domain, with increasing level of detail toward the bottom of the hierarchy which is consisting of entities. In the legal use case we considered, the concepts were adapted from section headings in a legal textbook, whereas references to law or legal cases inside the textbook became entities. The design of this tool is refined following various steps such as gathering user needs, pain points of an existing visualization, prototyping, testing, and refining. The resulting interface offers users several key features such as dynamic search and filter, explorable concept nodes, and a preview of leaf nodes at every stage. A high-fidelity prototype was created to test our theory and design. To test our concept, we used the System Usability Scale as a way to measure the prototype's usability, a task-based survey to asses the tool's ability in assisting users in gathering information and interacting with the prototype, and finally mouse tracking to understand user interaction patterns. Along with this, we gathered audio and video footage of users when participating in the study. This footage also helped us in getting feedback when the survey responses required further information. The data collected provided valuable insights to set the directions for extending this study. As a result, we have accounted for varying hierarchy depths, longer text spans than only one to two words in the elements of the hierarchy, searchability, and exploration of the hierarchies. At the same time, we aimed for minimizing visual clutter and cognitive overload. We show that existing approaches are not suitable to visualize the type of data which we support with our visualization.

Design and development of a self-care application for patients with liver cirrhosis.

Due to the capabilities of the mobile application in the self-care of patients, the present study was conducted to design and evaluate a mobile-based self-care application for patients with liver cirrhosis. Liver cirrhosis is a progressive and chronic disease that, if left untreated, leads to liver cancer and, finally, the death of the patient. This study was conducted in six phases, including determining and confirming the validity of the minimum data set and capabilities for the application, designing a conceptual and logical model and determining the technical capabilities, designing the application, evaluating the prototype usability in a laboratory environment by technical experts, evaluation of the application usability in a real environment by 30 patients with QUIS (Questionnaire of User Interface Satisfaction) questionnaire. The designed application has capabilities such as calculating the patient's MELD score (Model for End-Stage Liver Disease), medication reminder, location in emergency, and conversation with the physician. The results showed that the patients evaluated the application with a score of 7.94 (out of 9 points) at a good level. The self-care application can help patients with liver cirrhosis and their families access the necessary information related to the special care of the patient at any time and place; it also helps better manage the patient's life, improve the quality of life, and monitor the patient. These applications can effectively manage chronic diseases by reducing the burden of referrals and costs.

Feature recognition in multiple CNNs using sEMG images from a prototype comfort test

ObjectiveDeep learning-based CNN networks have recently been investigated to solve the problem of body posture recognition based on surface electromyographic signals (sEMG). Influenced by these studies, to develop a combined approach of sEMG and CNNs in the study of human-product interactions and the impact of body comfort, and to compare the advantages and disadvantages of various CNNs networks. MethodsIn this study, sEMG measurements were carried out by building a prototype usability experiment, and the data were divided into four categories, with two types of datasets: training and testing. Four CNNs, LeNet-5, VGGNet-11, InceptionNet V4, and DenseNet, were used for the recognition of sEMG images. ResultsDenseNet is another type of convolutional neural network with deep layers, which has a unique advantage over other algorithms. unique advantages over other algorithms. DenseNet has fewer layers and better accuracy than InceptionNet V4, but not only does it bypass enhanced feature reuse, but its network is easier to train and has some regularization effects, while also mitigating the problems of gradient disappearance and model degradation. ConclusionThese findings could lead to a more appropriate CNN model and a useful tool for developing comfort judgments of surface EMG signals, furthering the development of products that come into contact with the human body without the need for routine retraining.

DERIVING TRUST-SUPPORTING DESIGN KNOWLEDGE FOR AI-BASED CHATBOTS IN CUSTOMER SERVICE: A USE CASE FROM THE AUTOMOTIVE INDUSTRY

ABSTRACTIn the automotive industry, companies are increasingly implementing Artificial Intelligence (AI)-based chatbots to support various processes, especially in the context of customer service. However, there currently is a lack of knowledge, especially systematically derived design knowledge, regarding customer trust in interacting with AI-based chatbots. In this context, a lack of security and transparency, limited social features, and the communication style and quality-related issues of AI-based chatbots are just a few aspects that inhibit customer trust in interacting with this innovative technology, thereby hindering the adoption of chatbots. To address this knowledge gap, we adopted a design theory-based approach and developed a design concept for trust-supporting design knowledge regarding customer interaction with an AI-based chatbot. Design science provides a structured development and evaluation process to support, for example, the adoption of AI-based chatbots. Drawing on trust-based literature, a use case in customer service in the automotive industry, and seven semi-structured expert interviews, we propose 10 meta/user requirements and four design principles for trust-supporting design elements as (e.g. social) signals (stimuli) regarding the interaction with AI-based chatbots. We developed two click prototypes over two evaluation cycles. Each evaluation included an online survey with 180 participants. The findings that were obtained make a valuable contribution to solving the described lack of design knowledge by developing and evaluating different design approaches in the form of prototypical user interfaces. Moreover, the results show that visible design elements such as transparent and factual security signals (stimuli) and trust seals have a significant impact on customer trust.

Self-help application for obsessive-compulsive disorder based on exposure and response prevention technique with prototype design and usability evaluation: Across-sectional study.

Obsessive-compulsive disorder (OCD) is a relatively common disorder that, due to its debilitating nature, significantly affects personal abilities, job performance, social adjustment, and interpersonal relationships. There are significant barriers to accessing evidence-based cognitive-behavioral therapy as a first-line treatment for obsessive-compulsive disorder. Mobile health applications (Apps) offer a promising way to improve access to evidence-based therapies while overcoming these barriers. The present study was to design and evaluate a prototype of a self-help application for people with OCD (the most common pattern of OCD) based on the exposure and response prevention (ERP) technique. This work was developed in four different phases. (1) Needs assessment: a thorough literature review, reviewing existing related programs and apps, and interviewing patients and psychiatrists; (2) Creating a paper prototype: considering the functional features identified in the previous phase using wireframe sketcher software. (3) Creating a digital prototype: developing an actual prototype using Axure RP software based on the information obtained from an expert panel's evaluation of the paper prototype. (4) Prototype usability evaluation: through a heuristic evaluation with experts and usability testing with patients using the SUS questionnaire. After requirement analysis, requirements were defined in the areas of information and educational elements, and functional capabilities. Prototypes designed based on identified requirements include capabilities such as in-app online self-help groups, assessing the severity of the symptoms of the disorder, psychological training, supportive treatment strategies, setting personalized treatment plans, tracking treatment progress through weekly reports provided, anxiety assessment, and setting reminders. The results of the heuristic evaluation with experts made it possible to identify how to provide information and implement the capabilities in a way that is more appropriate and easier for the user.

Transforming Healthcare Analytics with FHIR: A Framework for Standardizing and Analyzing Clinical Data.

In this study, we discussed our contribution to building a data analytic framework that supports clinical statistics and analysis by leveraging a scalable standards-based data model named Fast Healthcare Interoperability Resource (FHIR). We developed an intelligent algorithm that is used to facilitate the clinical data analytics process on FHIR-based data. We designed several workflows for patient clinical data used in two hospital information systems, namely patient registration and laboratory information systems. These workflows exploit various FHIR Application programming interface (APIs) to facilitate patient-centered and cohort-based interactive analyses. We developed an FHIR database implementation that utilizes FHIR APIs and a range of operations to facilitate descriptive data analytics (DDA) and patient cohort selection. A prototype user interface for DDA was developed with support for visualizing healthcare data analysis results in various forms. Healthcare professionals and researchers would use the developed framework to perform analytics on clinical data used in healthcare settings. Our experimental results demonstrate the proposed framework's ability to generate various analytics from clinical data represented in the FHIR resources.

Feasibility, Usability, and Safety of ParaGym, an Intelligent Mobile Exercise App for Individuals With Paraplegia: Protocol for a Pilot Block-Randomized Controlled Trial

Exercise is crucial for individuals with paraplegia to reduce the risk of secondary diseases and improve independence and quality of life. However, numerous barriers such as inadequate accessibility restrict their participation in exercise programs. Digital exercise apps can help overcome these barriers. Personalization is considered a crucial feature of mobile exercise apps, as people with paraplegia have individual requirements regarding exercise programs depending on their level of impairment. Despite the increasing popularity of mobile exercise apps, there are none available that target the individual needs of this cohort. The ParaGym mobile exercise app prototype was designed to automatically tailor exercise sessions to the individual needs of users with paraplegia. This study aims to evaluate the feasibility, usability, safety, and preliminary effectiveness of the ParaGym mobile exercise app prototype. This pilot block-randomized controlled feasibility trial will include 45 adult participants with paraplegia. Eligible participants will be block randomized to either the intervention or waitlist control group. The intervention group will perform a 6-week exercise program using the ParaGym mobile exercise app, comprising three 35-minute exercise sessions per week. The waitlist control group will continue their usual care and receive access to the app after study completion. Participants will record all exercise sessions conducted with the app as well as additional exercise sessions conducted during the study period using exercise diaries. The primary outcomes include feasibility, usability, and safety. Feasibility will be assessed through semistructured interviews, study adherence, and retention rates. Usability will be measured using the System Usability Scale. Safety will be determined by the occurrence of adverse events. Secondary outcomes include the effects of the intervention on peak exercise capacity (VO2 peak); handgrip strength; independence, which will be measured using the Spinal Cord Independence Measure III (SCIM III); and health-related quality of life, which will be measured using the Short Form-36 Health Survey (SF-36). Recruitment commenced in November 2022. Overall, 12 participants were enrolled at the time of submission. Data collection commenced in January 2023, with completion expected in April 2023. To the best of our knowledge, this is the first study to assess the feasibility, usability, and safety of an intelligent mobile exercise app for individuals with paraplegia. Thereafter, the app should be adapted according to the findings of this trial. Future trials with an updated version of the app should aim for a larger sample size, longer intervention duration, and more diverse target group. In the long term, a fully marketable version of the ParaGym app should be implemented. This would increase the access to personalized, independent, and evidence-based exercise training for this cohort and, in the future, other people who use wheelchairs.

Microarray patch for HIV prevention and as a multipurpose prevention technology to prevent HIV and unplanned pregnancy: an assessment of potential acceptability, usability, and programmatic fit in Kenya.

Microarray patches (MAPs), a novel drug delivery system, are being developed for HIV pre-exposure prophylaxis (PrEP) delivery and as a multipurpose prevention technology (MPT) to protect from both HIV and unintended pregnancy. Prevention technologies must meet the needs of target audiences, be acceptable, easy to use, and fit health system requirements. We explored perceptions about MAP technology and assessed usability, hypothetical acceptability, and potential programmatic fit of MAP prototypes using focus group discussions (FGD), usability exercises, and key informant interviews (KII) among key populations in Kiambu County, Kenya. Adolescent girls and young women (AGYW), female sex workers (FSW), and men who have sex with men (MSM) assessed the usability and acceptability of a MAP prototype. Male partners of AGYW/FSW assessed MAP acceptability as partners of likely users. We analyzed data using NVivo, applying an inductive approach. Health service providers and policymakers assessed programmatic fit. Usability exercise participants applied a no-drug, no-microneedle MAP prototype and assessed MAP features. We implemented 10 FGD (4 AGYW; 2 FSW; 2 MSM; 2 male partners); 47 mock use exercises (19 AGYW; 9 FSW; 8 MSM; 11 HSP); and 6 policymaker KII. Participants reported high interest in MAPs due to discreet and easy use, long-term protection, and potential for self-administration. MAP size and duration of protection were key characteristics influencing acceptability. Most AGYW preferred the MPT MAP over an HIV PrEP-only MAP. FSW saw value in both MAP indications and voiced need for MPTs that protect from other infections. Preferred duration of protection was 1-3 months. Some participants would accept a larger MAP if it provided longer protection. Participants suggested revisions to the feedback indicator to improve confidence. Policymakers described the MPT MAP as "killing two birds with one stone," in addressing AGYW needs for both HIV protection and contraception. An MPT MAP is aligned with Kenya's policy of integrating health care programs. MAPs for HIV PrEP and as an MPT both were acceptable across participant groups. Some groups valued an MPT MAP over an HIV PrEP MAP. Prototype refinements will improve usability and confidence.

Design and usability evaluation of a mobile-based-self-management application for caregivers of children with severe burns.

Paediatric burns are a major public health issue because of long-term physical, psychological and social consequences and the high cost of treatment. The aim of this study was to design and evaluate a mobile-based self-management application for caregivers of children with severe burns. A participatory design technique was employed to develop the Burn application, which included three main phases: the determination of application requirements, the design and evaluation of the low-fidelity prototype, and the design and evaluation of the high-fidelity prototypes. In the first phase, application requirements were determined via validated paper questionnaires using the Delphi technique. In the second step, a low-fidelity prototype was prepared using conceptual models and evaluated through a focus group with specialists. Seven specialists reviewed the application and evaluated how this prototype meets functional requirements and objectives. The third phase was performed in three stages. First, the high-fidelity prototype was designed and developed by the JAVA programming language. Second, a cognitive walk-through was carried out to show how users can interact with the mobile application and how it works. Third, this program was installed on the mobile phones of 28 caregivers of burned children, eight IT experts, and two general surgeries, and the prototype's usability was evaluated. In the present study, most caregivers of children with burns stated that after discharge, they face problems regarding infection control and wound care (4.07) and how to perform physical activity (4.12). User registration, educational materials, caregiver-clinician communication, chat box, and appointment booking, safe login were the most important characteristic of the Burn application. Mean usability evaluation scores were in the range of 7.92 ± 0.238 to 8.10± 0.103, which is considered at a "good" level. From the Burn program design experience, it can be concluded that co-design with health care specialists can significantly support and meet the specialists' and patients' needs and ensure the program's usefulness. In addition, application evaluation by users involved and not involved in the application design process can help enhance usability.

Usability of the IDDEAS prototype in child and adolescent mental health services: A qualitative study for clinical decision support system development.

Child and adolescent mental health services (CAMHS) clinical decision support system (CDSS) provides clinicians with real-time support as they assess and treat patients. CDSS can integrate diverse clinical data for identifying child and adolescent mental health needs earlier and more comprehensively. Individualized Digital Decision Assist System (IDDEAS) has the potential to improve quality of care with enhanced efficiency and effectiveness. We examined IDDEAS usability and functionality in a prototype for attention deficit hyperactivity disorder (ADHD), using a user-centered design process and qualitative methods with child and adolescent psychiatrists and clinical psychologists. Participants were recruited from Norwegian CAMHS and were randomly assigned patient case vignettes for clinical evaluation, with and without IDDEAS. Semi-structured interviews were conducted as one part of testing the usability of the prototype following a five-question interview guide. All interviews were recorded, transcribed, and analyzed following qualitative content analysis. Participants were the first 20 individuals from the larger IDDEAS prototype usability study. Seven participants explicitly stated a need for integration with the patient electronic health record system. Three participants commended the step-by-step guidance as potentially helpful for novice clinicians. One participant did not like the aesthetics of the IDDEAS at this stage. All participants were pleased about the display of the patient information along with guidelines and suggested that wider guideline coverage will make IDDEAS much more useful. Overall, participants emphasized the importance of maintaining the clinician as the decision-maker in the clinical process, and the overall potential utility of IDDEAS within Norwegian CAMHS. Child and adolescent mental health services psychiatrists and psychologists expressed strong support for the IDDEAS clinical decision support system if better integrated in daily workflow. Further usability assessments and identification of additional IDDEAS requirements are necessary. A fully functioning, integrated version of IDDEAS has the potential to be an important support for clinicians in the early identification of risks for youth mental disorders and contribute to improved assessment and treatment of children and adolescents.

ReachCare Mobile Apps for Patients Experiencing Suicidality in the Emergency Department: Development and Usability Testing Using Mixed Methods.

Many individuals with suicide risk present to acute care settings such as emergency departments (EDs). However, staffing and time constraints mean that many EDs are not well equipped to deliver evidence-based interventions for patients experiencing suicidality. An existing intervention initiated in the ED for patients with suicide risk (Emergency Department Safety Assessment and Follow-up Evaluation [ED-SAFE]) has been found to be effective but faces trenchant barriers for widespread adoption. On the basis of the ED-SAFE intervention, we aimed to develop 2 apps for patients with suicide risk: a web app guiding patients through safety planning in the ED (ED app) and a smartphone app providing patients components of the ED-SAFE program on their phones after discharge (patient app). We then tested the usability of these apps with patients presenting to the ED with suicide risk. Using a user-centered design framework, we first developed user personas to explore the needs and characteristics of patients who are at risk for suicide using inputs from clinicians (n=3) and suicidologists (n=4). Next, we validated these personas during interviews with individuals with lived experience of suicidality (n=6) and used them to inform our application designs. We field-tested the apps with ED patients presenting with suicide risk (n=14) in 2 iterative cycles to assess their usability and engagement using a mixed methods approach. We also rated the quality and fidelity of the safety plans created. We developed 2 interoperable and complementary apps. The first is a web app designed for use on a tablet device during ED admission that guides the patient by creating a safety plan using a chatbot-style interface. The second is a smartphone app for use after discharge and allows the patient to view, edit, and share their completed safety plan; access self-care education, helplines, and behavioral health referrals; and track follow-up appointments with the study clinician. The initial prototype usability testing (n=9) demonstrated satisfactory scores (ED app System Usability Scale [SUS], mean 78.6/100, SD 24.1; User Engagement Scale, mean 3.74/5, SD 0.72; patient app SUS, mean 81.7/100, SD 20.1). After refining the apps based on participant feedback, the second cycle testing (n=5) showed improvement (ED app SUS, mean 90.5/100, SD 9.9; User Engagement Scale, mean 4.07/5, SD 0.36; patient app SUS, mean 97.0/100, SD 1.9). The quality ratings for completed safety plans were satisfactory (Safety Planning Intervention Scoring Algorithm-Brief, mean 27.4, SD 3.4). By adopting a user-centered approach and creating personas to guide development, we were able to create apps for ED patients with suicide risk and obtain satisfactory usability, engagement, and quality scores. Developing digital health tools based on user-centered design principles that deliver evidence-based intervention components may help overcome trenchant implementation barriers in challenging health care settings.

E-learning user interface design for lecturers based on usability scale system approach (Case Study: E-Learning Universitas Muhammadiyah Magelang)

Universitas Muhammadiyah Magelang provides an online learning service portal through an e-learning website MOCA. However, the low level of use of the MOCA website and the usability problems that usually arise in MOCA, indicate the need for usability testing. Usability testing is carried out to measure usability aspects, namely: effectiveness, efficiency, and user satisfaction. This study used a System Usability Scale questionnaire which was tested on 61 lecturers. This study aims to measure usability aspects according to the user's subjective assessment. The results of the study can describe the level of usability of MOCA from the user's point of view. the results of the MOCA usability test using the SUS method got a score of "64" and this figure is still below the average (below average) of 68. For acceptable ranges, it shows that the current MOCA is in a "marginal (high)" position, for the grade scale gets a “D” predicate, and for adjective ratings it can be said to be “OK” and that means the current MOCA quality score is acceptable but needs a lot of improvement. In addition, this study provides recommendations in the form of a prototype designed based on suggestions from respondents and then tested based on the heuristic aspects of the relevant journal. The prototype design that has been designed is tested on 5 respondents as evaluators. The results of the heuristic test obtained were "4.32" which means 5 respondents were "satisfied" with the prototype user interface design proposed by the researcher.

A substance user-self fit perception increases identification as a user of the substance.

We tested whether greater identification as a user of a substance (i.e., perceived general associations between oneself and use of the substance, the group of people who use the substance, and/or the substance itself) results from a theorized source-perceived fit between one's own identity and one's perception of the identity of being a user of the substance. We also tested whether this effect is stronger the more the group of people who use the substance is perceived as an entity and the more the prototypical user of the substance is perceived as having a favorable identity. We conducted two correlational and two (preregistered) experimental investigations of drinker identity and marijuana user identity. In all studies, substance user identity was positively associated with substance user-self fit perception. In both correlational studies, this relationship was stronger the more the group of people who use the substance was perceived as an entity. In the drinker identity correlational study, this relationship was also stronger the more it was perceived that the prototypical drinker has a favorable identity. A substance user-self fit perception could be addressed to reduce identification as a user of the substance in efforts to prevent hazardous use.
