Implementing integrated online prevention to reduce the risk of both obesity and eating disorders, in the school setting, is a promising approach. The challenge is to develop highly user-friendly and motivating programs, to foster adherence and effectiveness. The purpose of this study was to evaluate the usability of such a universal prevention program for students aged 14–19 years, and to address engagement issues. A mixed-methods approach was chosen, consisting of a think-aloud task, a semi-structured interview, and a questionnaire including items on sociodemographic characteristics and the System Usability Scale (SUS). Usability tests were conducted in two rounds, with five adolescents participating per round. Mean score in the SUS was 92.5 of 100 points (range 85–100), in the second round, after some adaptations from the participants’ feedback. In the course of the think-aloud tasks and interviews, five major themes emerged—visual design, navigation, mode of transfer, content, and engagement conditions. Interesting headlines, gamification, and monitoring tools are crucial for engagement. Apart from the importance of using the program during school hours, the study showed that problems currently perceived as important by the target group, need to be considered and addressed, prior to offering them prevention programs, which highlights the importance of a user-centered design.

BACKGROUND Stressful situations during intraoperative emergencies have negative impact on human cognitive functions. Consequently, task performance may decrease and patient safety may be compromised. Cognitive aids can counteract these effects and support anesthesiologists in their crisis management. The Professional Association of German Anesthesiologists set up a project to develop a comprehensive set of digital cognitive aids for intraoperative emergencies. A parallel development for several software platforms and stationary and mobile devices will accommodate the inhomogeneity of the information technology infrastructure within German anesthesia departments. OBJECTIVE This paper aimed to provide a detailed overview of how the task of developing a digital cognitive aid for intraoperative crisis management in anesthesia was addressed that meets user requirements and is highly user-friendly. METHODS A user-centered design (UCD) process was conducted to identify, specify, and supplement the requirements for a digital cognitive aid. The study covered 4 aspects: analysis of the context of use, specification of user requirements, development of design solutions, and evaluation of design solutions. Three prototypes were developed and evaluated by end users of the application. Following each evaluation, the new requirements were prioritized and used for redesign. For the first and third prototype, the System Usability Scale (SUS) score was determined. The second prototype was evaluated with an extensive Web-based questionnaire. The evaluation of the third prototype included a think-aloud protocol. RESULTS The chosen methods enabled a comprehensive collection of requirements and helped to improve the design of the application. The first prototype achieved an average SUS score of 74 (SD 12), indicating good usability. The second prototype included the following main revisions: 2-column layout, initial selection of patient type (infant, adult, or parturient), 4 offered search options, and the option to check off completed action steps. Its evaluation identified the following major revision points: add quick selection for resuscitation checklists, design the top bar and tabs slightly larger, and add more pictograms to the text. The third prototype achieved an average SUS score of 77 (SD 15). The evaluation of the think-aloud protocol revealed a good intuitiveness of the application and identified a missing home button as the main issue. CONCLUSIONS Anesthesiology—as an acute medical field—is particularly characterized by its high demands on decision making and action in dynamic, or time-critical situations. The integration of usability aspects is essential for everyday and emergency suitability. The UCD process allowed us to develop a prototypical digital cognitive aid, exhibiting high usability and user satisfaction in the demanding environment of anesthesiological emergencies. Both aspects are essential to increase the acceptance of the application in later stages. The study approach, combining different methods for determining user requirements, may be useful for other implementation projects in a highly demanding environment.

SummaryHealth information exchange (HIE) between Poison Control Centers (PCCs) and Emergency Departments (EDs) could improve care of poisoned patients. However, PCC information systems are not designed to facilitate HIE with EDs; therefore, we are developing specialized software to support HIE within the normal workflow of the PCC using user-centered design and rapid prototyping.To describe the design of an HIE dashboard and the refinement of user requirements through rapid prototyping.Using previously elicited user requirements, we designed low-fidelity sketches of designs on paper with iterative refinement. Next, we designed an interactive high-fidelity prototype and conducted scenario-based usability tests with end users. Users were asked to think aloud while accomplishing tasks related to a case vignette. After testing, the users provided feedback and evaluated the prototype using the System Usability Scale (SUS).Survey results from three users provided useful feedback that was then incorporated into the design. After achieving a stable design, we used the prototype itself as the specification for development of the actual software. Benefits of prototyping included having 1) subject-matter experts heavily involved with the design; 2) flexibility to make rapid changes, 3) the ability to minimize software development efforts early in the design stage; 4) rapid finalization of requirements; 5) early visualization of designs; 6) and a powerful vehicle for communication of the design to the programmers. Challenges included 1) time and effort to develop the prototypes and case scenarios; 2) no simulation of system performance; 3) not having all proposed functionality available in the final product; and 4) missing needed data elements in the PCC information system.

BACKGROUND By offering the ability to immediately communicate with health care providers, digital health apps may significantly bolster the therapeutic relationship. Increasing opportunities of engagement with a digital tool, self-monitoring tools show confer promise in allowing patients to go through periods in between in-clinic visits. Little is known however, regarding the usage of the apps and whether communication between providers and app users in fact encourages usage. OBJECTIVE The objective of this study was to investigate the users of an app for eating disorders and summarize the characteristics of usage, characteristics of communication (i.e. messages sent and received), and assess whether the degree of communication and the degree of app usage (of the main features of the app precluding provider contact) were related. METHODS Users of an app for eating disorders (Tregarthen et al) consented for their de-identified, aggregate level data to be utilized for research. Records of five hundred users were randomly sampled from May 2017 to July 2017. All users in the sampled cohort were linked to a clinician. Raw data included 97,732 observations of meal logs submitted via app across 500 individuals. RESULTS Our data demonstrated a high degree of variability across users in their engagement patterns of the app. Receiving more messages on average had a greater effect on usage than sending messages, implying that being checked in on by clinicians may encourage users to engage more with their app. Data also demonstrated that there were multiple phenotypes in terms of preferences regarding communication – while a portion of users seemed to benefit, a large minority did not demonstrate a change in usage based on the frequency of communication. CONCLUSIONS Understanding usage phenotypes can be instrumental in helping clinician and apps understand who their user is. This work demonstrates that variability among the user population in terms of usage and communication styles, as well as usage and behavior. This information can ultimately be leveraged for guiding effective treatment delivery.

Conventional vascular intervention (VI) procedures are typically performed manually under exposure to X-rays, whereby several problems are presented that need to be addressed owing to the patients and doctors being exposed to large amounts of radiation. In such cases, employing radiation protection units is not a long-term solution to avoid physical damage. Therefore, to overcome these issues, we propose a robotic VI system in this study. Moreover, we compare the extent of radiation exposure in the case of the conventional manual VI procedure with that in the case of the robotic procedure. The radiation exposure is then analyzed from the perspective of the doctor. Subsequently, the results of usability tests for two proposed master devices are presented in terms of the NASA task load index (NASA-TLX) and the system usability scale (SUS) score. To verify the effectiveness of the robotic VI system, animal experiments are conducted using a pig model. Among the two types of master devices tested with the proposed robotic VI system, the ergonomically designed 2-degree-of-freedom master device is found to be more effective than the joystick-type device in terms of the usability test scores. Hence, the proposed robotic VI procedure is shown to be advantageous in terms of reducing radiation exposure and improving usability.

BackgroundThree cognitive constructs are risk factors for eating disorders: undue influence of weight and shape, concern about weight and shape, and body dissatisfaction (BD). Undue influence, a diagnostic criterion for eating disorders, is postulated to be closely associated with self-esteem whereas BD is postulated to be closely associated with body mass index (BMI). We understand less about the relationships with concern about weight and shape. The aim of the current investigation was examine the degree of overlap across these five phenotypes in terms of latent genetic and environmental risk factors in order to draw some conclusions about the similarities and differences across the three cognitive variables.MethodA sample of female Australian twins (n=1056, including 348 complete pairs), mean age 35 years (s.d.=2.11, range 28–40), completed a semi-structured interview about eating pathology and self-report questionnaires. An independent pathways model was used to investigate the overlap of genetic and environmental risk factors for the five phenotypes.ResultsIn terms of variance that was not shared with other phenotypes, self-esteem emerged as being separate, with 100% of its variance unshared with the other phenotypes, followed by undue influence (51%) and then concern (34%), BD (28%) and BMI (32%).ConclusionsIn terms of shared genetic risk, undue influence and concern were more closely related than BD, whereas BMI and BD were found to share common sources of risk. With respect to environmental risk factors, concern, BMI and BD were more closely related to each other than to undue influence.

The assistive equipment provision process is routinely carried out with patients to mitigate fall risk factors via the fitment of assistive equipment within the home. However, currently, over 50% of assistive equipment is abandoned by the patients due to poor fit between the patient and the assistive equipment. This paper explores clinician perceptions of an early stage three-dimensional measurement aid prototype, which provides enhanced assistive equipment provision process guidance to clinicians. Ten occupational therapists trialled the three-dimensional measurement aid prototype application; think-aloud and semi-structured interview data was collected. Usability was measured with the System Usability Scale. Participants scored three-dimensional measurement aid prototype as ‘excellent’ and agreed strongly with items relating to the usability and learnability of the application. The qualitative analysis identified opportunities for improving existing practice, including, improved interpretation/recording measurements; enhanced collaborative practice within the assistive equipment provision process. Future research is needed to determine the clinical utility of this application compared with two-dimensional counterpart paper-based guidance leaflets.

Fitness as a healthy lifestyle implementation helps to improve the social, mental and physical well-being components. Several scientists have indicated that there is a connection between social belonging and physical activity (PA) as the structural component of a healthy lifestyle (Walseth, 2006; Walseth & Fasting, 2004; Antonsich, 2010; Yuval-Davis, 2006; Anthias, 2006; Pinquart & Sorensen, 2001; Everard et. al., 2000). That is why the goal of the research is to develop and apply a social belonging promotion programme for women in fitness programme and to determine the changes in the lifestyle structural component health promoting PA. 10 women involved in fitness classes in small groups (2-4 people) participated in the case study, where in addition to PA social belonging promotion events were organized for all women together. In order to evaluate the structural components of social belonging and PA level and type, questionnaires adapted in Latvia and a semi-structured interview was used. Applying the social belonging promotion programme for women in fitness creates statistically significant changes in such structural components as sense of commitment (p<0.01), perception of interpersonal relations (p<0.01). By additionally promoting social belonging in fitness, women perceive the group better, are willing to spend more time with it; that, in turn, positively affects the willingness to be physically and socially active on a daily basis.

Eating disorders are multifaceted mental health problems which require medical treatments and counseling from a psychological expert.In extreme condition,these eating disorders can cause serious health problems and may be lethal if these are not diagnosed and treated timely.Eating Disorder Hope organization has conducted a survey which revealed thatalmost 40% of teen age girls were suffering from at least one kind of eating disorder while91% of young females do dieting to reduce their weight. It has been estimated that about one million males and ten million females suffer from various types of eating disorders.  Bulimia nervosa is one of the eating disorders. It oftens develops in teenage or early adulthood.It is common in women than men. In bulimia nervosa, a person usually eats a lot in a short period of time. It seems that the personcannot control himself fromeating food. It happens until they are painfully full and then they will purge to end their discomfort and to compensate their calories. They will purge by forced vomitinglaxatives,diuretics or excessive exercise.Frequent self-induced vomiting can contribute to inflammation of parotidgland and can result in hand calluses. It is more common in families appearing in generations.There are many risk factors for this disease like being overweight/obesity, socio-cultural pressures to have a well tonned body, psychological impacts resulting in stress and poor self-esteem. Dieting has become a part of our culture. There are manysymptoms of bulimia. For example, patients live in a fear of gaining weight, they go through the repeated episodes of abnormal eating large amounts of food in single sitting. There is a feeling which develops in patients that they cannot control what they eat and what type of food they eat, and after bingering they are forcing themselves to vomit and do more exercise to stop weight gain. If we leave bulimia untreated it will cause kidney problems, irregular heart rhythms, digestive issues and dental problems etc. In time treatment and diagnosis of bulimia helps the person to recover well and quick and the person can get rid of this disorder completely otherwise it can be life threatening. A person experiences bulimia to manage the emotional pain he is undergoing but it only worsens the condition and the response may be to ramp up obsessive thoughts and compulsive behaviors. Nearly half of bulimia patients have a co-occuring mood disorder and more than half of bulimia patients have co-occuring anxiety disorders. Self-harm is a common condition affecting 34% of those with bulimia. Recent studies on bulimia show that in 10-15% of male members of our society who are living with this disorder, risk of suicide has increased. Statistics show that relapse of this disorder isvery common.Relapse is occurring in about30-50% of the cases, and it isleading to common cause of death in suicide.For treatment of bulimia nervosa, you may need to go for several types. Bulimia can be reduced by taking anti-depressants or psychotherapy, but using both in combination is more fruitful to overcome this disorder. Psychotherapy is very important for patients, in which the person goes to the psychiatrist to discuss the issues related to bulimia. Educating the patient on nutrition also helps in this regard. Anutritionist can prescribe the food by which a person will feel the cravings for food to a lesser extent. In severe conditions,the patient can be admitted to a hospital because sometimes there is a need fortreatment in a hospital. In many cases it is not possible to eradicate it completely.But before the situation goes wrong, we can guide a person to lead a healthier life with the help of professionally used treatments. Since we are living in an era where everyone is busy, it is important to guide and educate the children about a healthy lifestyle. There is a need to give them confidence about their physical appearance, no matter what their weight, size and shape is. Enjoyable family meals should be arranged on daily basis or regularly. Talks on physical appearances, body weight and dieting should be discouraged at home. Exercise, walk, activities like sports and swimming can help young generation to adopt a healthy lifestyle and streamline their daily life. If you observe that someone in your friends or relatives is having issues related to food which is indicating thathe or she can possibly has an eating disorder, you should talk to the person supportively and discuss the issue and help them in any way you can before the situation gets worse.

The importance of participatory design (PD) is progressively increasing thanks to its capacity to explore a wide variety of concepts, thus increasing the opportunity to create a successful product. In fact the design process should not be a solo activity, as designers often need inputs and other points of view, especially from end-users. According to the ultimate idea of PD, end-users are actively involved in the various activities of the product development to ensure that their needs and desires are satisfied. This paper presents a novel approach to the participatory design of product interfaces in a user-centered design (UCD) process. The approach is based on an interactive tool that allows end-users to design custom user interfaces of household appliances taking advantage of their own needs and experiences. The tool incorporates the analytical and more abstract knowledge of the designers codified in the form of aesthetical, technological and manufacturing constraints (i.e., limitations in the number and geometry of interface components, a limited number of colors, a discretization of the area where interface widgets are placed). This solution allows the end-users to directly design their favorite interface without the interference of any other subject. Through an accurate analysis of the choices done by the users, the designers are able to access to the deepest level of the users’ expression in order to catch their latent needs and tacit knowledge. The tool has been designed in order to make possible to immediately perform usability tests on the designed interface by using a Mixed Reality prototype. The paper describes the development of the tool and proposes a methodology that has been specifically addressed to include this tool in a design process based on UCD principles. Both the tool and the methodology are presented through the description of a case-study related to the redesign of a washing machine dashboard. Experimental results show that the proposed tool can be an effective support to design product interfaces during PD sessions.
