“…Several prior studies have investigated the use of these search interfaces for users with low domain knowledge [14], who speak a language that is different than that of the Web form [15], who are children [16], or older adults [17], all who share characteristics with our task and population. These studies have demonstrated that even the simplest keyword-based search interfaces are unusable for many users and that special design considerations—such as simplifying results [17] and providing language and interaction support [16]—are important for disadvantaged users. Users may also be influenced by contextual cues when evaluating results from search engines [18] and those with low health literacy may be particularly susceptible to these cues when evaluating search results, relying on such features as position in search results, quality of pictures, and celebrity endorsements [19].…”

BackgroundConventional Web-based search engines may be unusable by individuals with low health literacy for finding health-related information, thus precluding their use by this population.ObjectiveWe describe a conversational search engine interface designed to allow individuals with low health and computer literacy identify and learn about clinical trials on the Internet.MethodsA randomized trial involving 89 participants compared the conversational search engine interface (n=43) to the existing conventional keyword- and facet-based search engine interface (n=46) for the National Cancer Institute Clinical Trials database. Each participant performed 2 tasks: finding a clinical trial for themselves and finding a trial that met prespecified criteria.ResultsResults indicated that all participants were more satisfied with the conversational interface based on 7-point self-reported satisfaction ratings (task 1: mean 4.9, SD 1.8 vs mean 3.2, SD 1.8, P<.001; task 2: mean 4.8, SD 1.9 vs mean 3.2, SD 1.7, P<.001) compared to the conventional Web form-based interface. All participants also rated the trials they found as better meeting their search criteria, based on 7-point self-reported scales (task 1: mean 3.7, SD 1.6 vs mean 2.7, SD 1.8, P=.01; task 2: mean 4.8, SD 1.7 vs mean 3.4, SD 1.9, P<.01). Participants with low health literacy failed to find any trials that satisfied the prespecified criteria for task 2 using the conventional search engine interface, whereas 36% (5/14) were successful at this task using the conversational interface (P=.05).ConclusionsConversational agents can be used to improve accessibility to Web-based searches in general and clinical trials in particular, and can help decrease recruitment bias against disadvantaged populations.

“…Evaluative YII studies are conducted under controlled or semi-controlled conditions to compare and explore the results of interactions with information systems. These studies focus on the issues youth encounter when seeking and retrieving information (Gossen et al, 2014(Gossen et al, , 2012, and/or the barriers the information system pose to youth (Jochmann-Mannak et al, 2016). These studies sometime employ field-based experimental designs, or quasiexperiments.…”

Youth information interaction (YII) research has focused on challenges youth encounter when interacting with information across different contexts. Although these studies have been fundamental to outline youth information behaviour, the absence of YII theoretical frameworks might limit our approach to contemporary issues, such as the increased use of apps and mobile devices for information searching. This paper presents a conceptual analysis of studies conducted between 1997-2020 to explore predominant epistemological stances and cognitive frameworks in YII. The conceptual analysis generated five typologies operationalizing YII studies in seven categories: epistemological stance, knowledge assumption, cognitive framework, study type, study design, theoretical framework, study outcomes, and applications. The findings suggest that YII research have converged to empiricist and rationalist stances supporting exploratory approaches. These findings elicit the urgency for the development of theoretical frameworks that support the validity of YII phenomena with the purpose of developing a new agenda for YII research.

Evaluation of a scatter/gather interface for supporting distinct health information search tasks

Web search engines are important gateways for users to access health information. This study explored whether a search interface based on the Bing API and enabled by Scatter/Gather, a well-known document-clustering technique, can improve health information searches. Forty participants without medical backgrounds were randomly assigned to two interfaces: a baseline interface that resembles typical web search engines and a Scatter/Gather interface. Both groups performed two lookup and two exploratory health-related tasks. It was found that the baseline group was more likely to rephrase queries and less likely to access generalpurpose sites than the Scatter/Gather group when completing exploratory tasks. Otherwise, the two groups did not differ in behavior and task performance, with participants in the Scatter/Gather group largely overlooking the features (key words, clusters, and the recluster function) designed to facilitate the exploration of semantic relationships between information objects, a potentially useful means for users in the rather unfamiliar domain of health. The results suggest a strong effect of users' mental models of search on their use of search interfaces and a high cognitive cost associated with using the Scatter/Gather features. It follows that novel features of a search interface should not only be compatible with users' mental models but also provide sufficient affordance to inform users of how they can be used. Compared with the interface, tasks showed more significant impacts on search behavior. In future studies, more effort should be devoted to identify salient features of health-related information needs.
