Background: Latin American countries show a fast-growing rate of non-communicable diseases (NCDs) and diet is a critical risk factor that must be properly assessed. Automated dietary assessment tools to collect 24-h dietary recalls (24HR) are lacking in Argentina. Objective: This study aimed to develop an open-access automated tool (MAR24) for collecting 24HR using a multiple pass method and a database containing foods and recipes commonly consumed in Argentina. Methods: MAR24 was developed based on data from 1,285 24HR provided by male and female participants aged 18 to 68 years from the six Argentinian geographical regions. The main structure and interface of the tool were designed using Visual Basic for Applications programming language in Excel Microsoft Office 365, integrating the five steps of the United States Department of Agriculture (USDA) Automated Multiple-Pass Method (AMPM) for the application of 24HR in Spanish. The tool underwent alpha testing and expert assessment to...
Usability test of an interactive dietary recording.
Dietary intake methods are used to collect one's diet habit which is essential in nutrition assessment. Food diary, food frequency questionnaire (FFQ) and 24-hour recalls are the most common dietary intake methods. However, they are not welcomed by most clients. Digital handheld devices are now readily available, and the cost of digital transmission is low. eDietary Intake Portal (the Portal) is a new developed interactive web-based system for recording dietary intake. In addition, the Portal also evaluates energy balance and nutrient balance on individual basis. Nutrition assessment could then be reported online and this serves an education tool for promoting nutrition information.. Clients could adjust their food intake gradually and learn from the assessment reports to eat in a more healthy way. Usability test was carried out to evaluate user acceptance of the Portal. A convenience sample of twenty participants was recruited. Seven male and thirteen female with mean (S.D.) age 33.43 (8.01) were asked to evaluate the Portal in 3 domains: system usability, information quality and interface quality. Average scores for the three domains ranged 2.60-3.05. The overall usability was 2.5. The Portal demonstrated a high usability, thus encouraged continuous dietary recording and facilitated nutrition education through Internet.

During recent years, the integration of technology has substantially improved self-reported dietary assessment methods, such as food frequency questionnaires (FFQ), food records, and 24-h recalls. To further reduce measurement error, additional innovations are urgently needed. Memory-related measurement error is one of the aspects that warrants attention, which is where new smartphone technologies and ecological momentary assessment (EMA) approaches provide a unique opportunity. In this article, we describe the DIASS study, which was designed to evaluate an innovative 2-h recall (2hR) smartphone-based methodology, against traditional 24-h recalls, FFQ, and biomarkers, to assess both actual and habitual dietary intake. It is hypothesized that a 2-h reporting window decreases reliance on memory and reporting burden, and increases data accuracy. We included 215 men (28%) and women (72%), with a mean ± SD age of 39 ± 19 years and a mean ± SD BMI of 23.8 ± 4.0. Most participants were hig...
Respondents’ evaluation of the 24-h dietary recall method (EPIC-Soft) in the EFCOVAL Project
European Journal of Clinical Nutrition, 2011
Background: To improve participation rate, accuracy and respondents' compliance, it is important to know the respondents' viewpoint. Objective: To evaluate respondents' preferences and perception about the EPIC-Soft (the software developed to conduct 24-h dietary recalls (24-HDRs) in the European Prospective Investigation into Cancer and Nutrition (EPIC) Study) 24-HDR interviews and to compare these preferences and perception between population groups (for example, between genders). Design: Data were collected in Belgium, Czech Republic, France, the Netherlands and Norway in 2007. Two 24-HDRs (face-toface and telephone administered) were conducted using EPIC-Soft. An evaluation questionnaire on different study aspects was completed by the respondents. Setting: Data were collected in the European Food Consumption Validation Study. Subjects: A convenience sample of 600 apparently healthy men and women, 45-65 years old and including all educational levels, were recruited (120 subjects per country). Differences among population groups were compared by means of the w 2-test. Results: A total of 585 respondents completed the evaluation questionnaire. In all, 88% experienced problems only to a low degree when answering face-to-face and telephone-administered 24-HDR using EPIC-Soft. A total of 15% would have preferred help of another person during the face-to-face interview in the study center (mainly men: Po0.001). Significantly, more subjects in the Netherlands and in Norway preferred two telephone (instead of face-to-face) interviews compared with the other countries (Po0.001). Conclusion: Most subjects only experienced problems to a low degree during the EPIC-Soft interviews. Differences in preferences and capabilities to answer the EPIC-Soft interviews were identified between population groups (for example, gender differences). Therefore, the methods and the design to be used in a survey should be adapted according to the study population, so as to optimize response rate and compliance.

Cognitive interviewing and usability testing share techniques and have similar origins in cognitive psychology. However, cognitive interviewing often precedes usability testing in survey pretesting, and each test yields different results. While it seems that administering the tests concurrently saves time and effort, there is little evidence that researchers test concurrently. In this study, we coordinated concurrent cognitive and usability testing. By concurrently testing the same survey with different participants (respondents and interviewers), issues with question wording and design were more efficiently addressed, leading to an improved questionnaire for both respondents and interviewers.

Background: Self-Completed Recall and Analysis of Nutrition (SCRAN24) is a prototype computerised 24-h recall system for use with 11-16 year olds. It is based on the Multiple Pass 24-h Recall method and includes prompts and checks throughout the system for forgotten food items. Methods and results: The development of SCRAN24 was informed by an extensive literature review, a series of focus groups and usability testing. The first stage of the recall is a quick list where the user is asked to input all the foods and drinks they remember consuming the previous day. The quick list is structured into meals and snacks. Once the quick list is complete, additional information is collected on each food to determine food type and to obtain an estimate of portion size using digital images of food. Foods are located within the system using a free text search, which is linked to the information entered into the quick list. A time is assigned to each eating occasion using drag and drop onto a timeline. The system prompts the user if no foods or drinks have been consumed within a 3-h time frame, or if fewer than three drinks have been consumed throughout the day. The food composition code and weight (g) of all items selected are automatically allocated and stored. Nutritional information can be generated automatically via the SCRAN24 companion Access database. Conclusions: SCRAN24 was very well received by young people and was relatively quick to complete. The accuracy and precision was close to that of similar computer-based systems currently used in dietary studies.
Achieving Quality Research with Formative Usability Testing
Drawing upon various studies and expert opinion, I will examine possible appropriate quality metrics for evaluating research using formative user testing.Quality research should be structured to be appropriate to the project, utilizing best methodological practices where feasible. Data gathered should be meaningful in that results are indicative of major usability problems and are actionable. Finally, quality research using formative testing should generate insight into understanding users and should provide information to address user needs. Mindful compromises against internal validity and reliability can be made to achieve these goals.

Development of computer-assisted interviewing (CAI) instruments is often resource-intensive and timeconsuming (Nicholls & Appel, 1994), especially compared with developing paper questionnaires. In addition to many of the same activities needed to create a paper instrument, the computer instrument must be programmed. Thus, developing a CA! instrument involves both the staff typically associated with questionnaire design (e.g., content specialists, statisticians) as well as programming staffto create the computerized instrument (Mockovak, 1996). Typically, however, people who are expert in questionnaire design are not also expert in the programming skills needed to implement a questionnaire on computer. As a result, the actual designers of questionnaires must work through intermediaries (programmers), with concomitant delays and the potential for miscommunication. Although CA! technologies have expanded, many procedures for designing CAI instruments are little more than the same proce...
Standardized Usability Questionnaires: Features and Quality Focus
Computer Science and Information Technology, 2016
For the last few decades more than twenty standardized usability questionnaires for evaluating software systems have been proposed. These instruments have been widely used in the assessment of usability of user interfaces. They have their own characteristics, can be generic or address specific kinds of systems and can be composed of one or several items. Some comparison or comparative studies were also conducted to identify the best one in different situations. All these issues should be considered while choosing a questionnaire. In this paper, we present an extensive review of these questionnaires considering their key features, some classifications and main comparison studies already performed. Moreover, we present the result of a detailed analysis of all items being evaluated in each questionnaire to indicate those that can identify users’ perceptions about specific usability problems. This analysis was performed by confronting each questionnaire item (around 475 items) with usab...
