Assessment of Usefulness of Randomized Control Trials in Child Health Research Published in 2007 and 2017.

OBJECTIVE: To examine how clinical usefulness in pediatric research with randomized controlled trials (RCTs) has changed over a 10-year period via a research usefulness tool composed of unique clinical usefulness criteria. STUDY DESIGN: We leveraged a pre-existing sample of child health RCTs published in 2007, used by our team in a previous study. Using the same methods, a research librarian executed a literature search in the Cochrane Central Register of Controlled Trials for the 2017 cohort. We included the first 300 eligible citations from the randomly ordered list for each year, creating two cohorts of 300 publications each, 1 in 2007 and 1 in 2017. Each publication was analyzed and data regarding primary and secondary outcomes, as well as 11 unique criteria of clinical usefulness, were extracted. Each publication was then graded using a tool created by our research team. After quality review, statistical analysis was then performed. RESULTS: Six hundred pediatric RCT publications were included in this review. The mean score increased from 6.07 in 2007 to 9.20 in 2017 (P < .001). Usefulness factors that saw the largest increase in reporting were context placement, funding statements, and conflict of interest statements, while patient centeredness, value for money, and raw data availability remained infrequently reported. CONCLUSION: Our results demonstrate that clinical usefulness of pediatric research improved over this 10-year period, but there are still areas that need a great deal of improvement in order to maximize clinical usefulness and reduce research waste.

How Do Adherence to COVID-19 Mitigation Measures and Its Predictors Change between 2020 and 2021? An Explorative Investigation in Eight European Union and Non-European Union Countries.

INTRODUCTION: Adherence to COVID-19 mitigation measures is an important vehicle that has contributed to the fight against the pandemic. The present study investigated potential changes of the level of adherence and its predictors between 2020 and 2021 in eight countries. METHODS: Adherence to COVID-19 measures and its potential predictors (perception of usefulness of the measures, rating of the governmental COVID-19 communication, mental health variables, COVID-19 burden) were compared between representative population samples from European Union countries (France, Germany, Poland, Spain, Sweden) and non-European Union countries (Russia, UK, USA) assessed in 2020 (N = 7,658) and 2021 (N = 8,244). RESULTS: In the overall sample, multiple analyses of variance revealed significantly higher levels of adherence to the measures, their perception as useful, positive mental health, and feelings of being well supported and well informed by governments in 2020 than in 2021. In contrast, feelings of being left alone and symptoms of depression, anxiety, and stress were significantly higher in 2021 than in 2020. In France, Poland, Spain, and the UK, the adherence level was significantly higher in 2020 than in 2021. In European Union countries, ratings of governmental communication were less positive, and levels of mental health were lower in 2021 than in 2020. In non-European countries, an opposite result pattern was found. CONCLUSION: The current results indicate a decrease in adherence to the mitigation measures and factors that could foster it. Potential ways how governments and authorities could enhance the population's trust in COVID-19 mitigation measures are discussed.

Usability, Engagement, and Report Usefulness of Chatbot-Based Family Health History Data Collection: Mixed Methods Analysis.

BACKGROUND: Family health history (FHx) is an important predictor of a person's genetic risk but is not collected by many adults in the United States. OBJECTIVE: This study aims to test and compare the usability, engagement, and report usefulness of 2 web-based methods to collect FHx. METHODS: This mixed methods study compared FHx data collection using a flow-based chatbot (KIT; the curious interactive test) and a form-based method. KIT's design was optimized to reduce user burden. We recruited and randomized individuals from 2 crowdsourced platforms to 1 of the 2 FHx methods. All participants were asked to complete a questionnaire to assess the method's usability, the usefulness of a report summarizing their experience, user-desired chatbot enhancements, and general user experience. Engagement was studied using log data collected by the methods. We used qualitative findings from analyzing free-text comments to supplement the primary quantitative results. RESULTS: Participants randomized to KIT reported higher usability than those randomized to the form, with a mean System Usability Scale score of 80.2 versus 61.9 (P<.001), respectively. The engagement analysis reflected design differences in the onboarding process. KIT users spent less time entering FHx information and reported more conditions than form users (mean 5.90 vs 7.97 min; P=.04; and mean 7.8 vs 10.1 conditions; P=.04). Both KIT and form users somewhat agreed that the report was useful (Likert scale ratings of 4.08 and 4.29, respectively). Among desired enhancements, personalization was the highest-rated feature (188/205, 91.7% rated medium- to high-priority). Qualitative analyses revealed positive and negative characteristics of both KIT and the form-based method. Among respondents randomized to KIT, most indicated it was easy to use and navigate and that they could respond to and understand user prompts. Negative comments addressed KIT's personality, conversational pace, and ability to manage errors. For KIT and form respondents, qualitative results revealed common themes, including a desire for more information about conditions and a mutual appreciation for the multiple-choice button response format. Respondents also said they wanted to report health information beyond KIT's prompts (eg, personal health history) and for KIT to provide more personalized responses. CONCLUSIONS: We showed that KIT provided a usable way to collect FHx. We also identified design considerations to improve chatbot-based FHx data collection: First, the final report summarizing the FHx collection experience should be enhanced to provide more value for patients. Second, the onboarding chatbot prompt may impact data quality and should be carefully considered. Finally, we highlighted several areas that could be improved by moving from a flow-based chatbot to a large language model implementation strategy.

A survey of the representativeness and usefulness of wastewater-based surveillance systems in 10 countries across Europe in 2023.

Wastewater-based surveillance (WBS) has become a widespread method to monitor transmission of SARS-CoV-2 and other human pathogens in Europe. We conducted a survey about WBS systems' objectives, approaches, representativeness and usefulness in 10 invited European countries in 2023, i.e. Austria, Belgium, Denmark, Finland, Greece, Hungary, Italy, Luxembourg, the Netherlands and Norway. All countries completed the study questionnaire about their SARS-CoV-2 WBS systems, and shared information about WBS of other pathogens as deemed relevant. SARS-CoV-2 WBS systems primarily monitored national and subnational trends (population coverage: 25-99%), and a majority (8/10) also tracked variant distribution. Nine of 10 countries reported that their SARS-CoV-2 WBS systems were representative of their population and all countries remarked that the findings were valuable for public health decision-making. Results were shared with relevant public health authorities and published via dedicated websites and/or dashboards. WBS systems of other pathogens were mostly in the early stages, with some countries implementing pilots. Notable exceptions were the well-established poliovirus surveillance systems in Finland, Italy and the Netherlands. This study brings understanding the diverse landscape of WBS in Europe, offering insights for future developments and collaborations. Furthermore, it highlights the need for further integration of WBS into other European surveillance systems.

Joint Developmental Trajectories of Novelty and Usefulness in Chinese Children's Creativity.

Creativity encompasses both novelty and usefulness, with novelty referring to the generation of unique and uncommon ideas, while usefulness pertains to the effectiveness and appropriateness of these ideas in addressing the given task. The comprehension of the process of coordinated development for children's novelty and usefulness, including the potential gender differences, is crucial; however, it still lacks clarity in the current academic discourse. To address these gaps, this study investigated the joint developmental trajectories of novelty and usefulness as well as the gender differences in trajectory group membership among Chinese children. A sample of primary school children (initial grade 3, N = 665; 46.4% girls; initial Mage = 8.60 years) were followed for three years. The results revealed a negative association between novelty and usefulness across all three time points. Through parallel-process latent class growth modeling, three distinct trajectories of novelty and usefulness were identified: the High Novelty Decline-Medium Usefulness Increase-Stability Group (66%), the Low Novelty Increase-High Usefulness Decline-Convergence Group (19%), and the Low Novelty Decline-High Usefulness Increase-Divergence Group (15%). These findings suggest that the development of children's creativity is influenced by a multifaceted pattern involving both novelty and usefulness. Moreover, gender differences in trajectory group membership were examined and discussed within the context of creativity development in Chinese children.

Evaluation of the usefulness and understandability of information leaflets on fall prevention from the perspective of hospital patients and their relatives.

BACKGROUND: Falls are a major problem among adults over 60 years. Multiple preventive measures must be taken. Written information leaflets can support the knowledge transfer and positively influence recall of the information provided. OBJECTIVE: The aim was to ensure usefulness and understandability of the information leaflets on home fall prevention from the target groups' perspective. METHODS: A cross-sectional survey study with a feedback questionnaire for patients and relatives was conducted at a university hospital in Austria. Quantitative data analysis and qualitative content analysis according to Schreier were performed. RESULTS: The majority (63.9%) of patients rated the overall impression as "very good". 44.2% of the relatives rated it as "very good" and 23% as "good". The question "appealing design" was the only one with a statistically significant difference between patients and relatives. Subgroup analysis has shown a statistically significant difference between educational groups regarding the questions "easy to read" and "easy to understand". CONCLUSION: It could be shown that the information leaflets were already well tailored to the target group. The few comments regarding understandability were considered to improve the content of the information leaflets. A further evaluation regarding the benefit of the fall prevention leaflets in discharge management should be performed.

Assessing the pertinence and usefulness of HIV and AIDS indicators for evaluating clinical care quality: Perspectives of health care professionals.

Following a systematic review of quality indicators employed in the evaluation of clinical care for individuals with HIV and AIDS, we performed "an exploratory study" that aims to assess the clinical significance and practical applicability of these indicators from the perspective of health care professionals (HCPs) specialising in HIV and AIDS care. Twenty-five HCPs filled out two questionnaires. From the initial list of 88 quality indicators, 50 were identified as the most relevant and useful in HIV and AIDS clinical care. Analysis was conducted on the individual indicators, and the outcomes were categorised into seven domains for clinical relevance and practical usefulness. Health care professionals deemed the functional organisational structure and the therapy domain to have the most pertinent and useful indicators among the seven different clinical domains, followed by the prevention domain.

Assessment of usefulness and reliability of YouTube™ videos on denture care.

INTRODUCTION: The world's population is in a demographic transition with a rising ageing population. Tooth loss is frequent among older people resulting in the replacement of natural teeth using complete or partial dentures. YouTube™ is the second most popular website in the world and is being increasingly used to access health care information. The aim of this study is to evaluate the usefulness and reliability of the information in YouTube™ videos regarding denture care. METHODS: The YouTube™ website was used to systematically search for videos using the keyword 'denture care'. Videos meeting the eligibility criteria were assessed separately by two independent researchers. The usefulness of the videos was assessed using the Global Quality Assessment Scale and a customized usefulness scoring scheme. Based on these scores, the usefulness of the videos was categorized as low, medium and high. A modified DISCERN tool (mDISCERN) was used for assessing reliability with scores ranging from 0 to 5. Other video characteristics like source/ownership of the videos, duration, views, likes, dislikes, number of days posted, like ratio, view ratio, interaction index and Video Power Index were also obtained. Statistical analysis was carried out using the Kruskal-Wallis test, Spearman correlation test and multiple linear regression analysis. RESULTS: A total of 120 videos were included. Based on the usefulness score, the usefulness of 65.8% of videos were classified as low, 32.5% were medium and 1.6% had high usefulness. The mDISCERN score for 74.2% of videos was 2 or below 2 indicating that the majority of videos had low reliability. Video characteristics did not differ significantly according to the usefulness of videos. Videos uploaded by dentists or dental hygienists had significantly higher usefulness scores (p < 0.001) in comparison to videos uploaded by other sources. However, reliability scores did not differ based on the sources of the videos. Video reliability was found to have a significant (B = 2.08, p < 0.001) positive association with video usefulness. CONCLUSION: YouTube™ cannot be recommended as the only source of information for denture care as most videos received low usefulness and reliability ratings in our study. Dentists and dental health professionals could take an active part in enhancing denture care-related content on YouTube™ and enable patients to have adequate and reliable knowledge of denture hygiene practices.

Designing a Community-Based Health Promotion Program for Older Adults Based on Perceived Usefulness, Service Experience, Perceived Value, and Behavioral Intention.

Improving nutritional intake contributes to maintaining the health and quality of life of the older population and reducing individual and societal healthcare costs. We collaborated with two community service hubs and a public health center in Taipei's Daan District to develop a personalized community-based health and nutrition program using service design. The design was validated through a model encompassing perceived usefulness, service experience, perceived value, and behavioral intention, analyzed using PLS-SEM modeling on 76 individuals. The results showed bidirectional influences among these factors. This study provides practical recommendations for formulating public health policies and health promotion programs for older adults.

AppIndels.com server: a web-based tool for the identification of known taxon-specific conserved signature indels in genome sequences. Validation of its usefulness by predicting the taxonomic affiliation of >700 unclassified strains of Bacillus species.

Taxon-specific conserved signature indels (CSIs) in genes/proteins provide reliable molecular markers (synapomorphies) for unambiguous demarcation of taxa of different ranks in molecular terms and for genetic, biochemical and diagnostic studies. Because of their predictive abilities, the shared presence of known taxon-specific CSIs in genome sequences has proven useful for taxonomic purposes. However, the lack of a convenient method for identifying the presence of known CSIs in genome sequences has limited their utility for taxonomic and other studies. We describe here a web-based tool/server (AppIndels.com) that identifies the presence of known and validated CSIs in genome sequences and uses this information for predicting taxonomic affiliation. The utility of this server was tested by using a database of 585 validated CSIs, which included 350 CSIs specific for ≈45 Bacillales genera, with the remaining CSIs being specific for members of the orders Neisseriales, Legionellales and Chlorobiales, family Borreliaceae, and some Pseudomonadaceae species/genera. Using this server, genome sequences were analysed for 721 Bacillus strains of unknown taxonomic affiliation. Results obtained showed that 651 of these genomes contained significant numbers of CSIs specific for the following Bacillales genera/families: Alkalicoccus, 'Alkalihalobacillaceae', Alteribacter, Bacillus Cereus clade, Bacillus Subtilis clade, Caldalkalibacillus, Caldibacillus, Cytobacillus, Ferdinandcohnia, Gottfriedia, Heyndrickxia, Lederbergia, Litchfieldia, Margalitia, Mesobacillus, Metabacillus, Neobacillus, Niallia, Peribacillus, Priestia, Pseudalkalibacillus, Robertmurraya, Rossellomorea, Schinkia, Siminovitchia, Sporosarcina, Sutcliffiella, Weizmannia and Caryophanaceae. Validity of the taxon assignment made by the server was examined by reconstructing phylogenomic trees. In these trees, all Bacillus strains for which taxonomic predictions were made correctly branched with the indicated taxa. The unassigned strains likely correspond to taxa for which CSIs are lacking in our database. Results presented here show that the AppIndels server provides a useful new tool for predicting taxonomic affiliation based on shared presence of the taxon-specific CSIs. Some caveats in using this server are discussed.

APLUS: A Python library for usefulness simulations of machine learning models in healthcare.

Despite the creation of thousands of machine learning (ML) models, the promise of improving patient care with ML remains largely unrealized. Adoption into clinical practice is lagging, in large part due to disconnects between how ML practitioners evaluate models and what is required for their successful integration into care delivery. Models are just one component of care delivery workflows whose constraints determine clinicians' abilities to act on models' outputs. However, methods to evaluate the usefulness of models in the context of their corresponding workflows are currently limited. To bridge this gap we developed APLUS, a reusable framework for quantitatively assessing via simulation the utility gained from integrating a model into a clinical workflow. We describe the APLUS simulation engine and workflow specification language, and apply it to evaluate a novel ML-based screening pathway for detecting peripheral artery disease at Stanford Health Care.

Beliefs about emotions predict psychological stress related to somatic symptoms.

BACKGROUND: Previous research has shown that the more people believe their emotions are controllable and useful (BECU), the less they generally report psychological distress. Psychological distress, in turn, impacts health outcomes, and is among the most frequently reported complaints in psychotherapeutic and psychosomatic practice. OBJECTIVE: We aimed to examine how BECU predicts psychological distress related to somatic symptoms in a prospective sample from the general population and to replicate this association in two cross-sectional samples of psychosomatic patients. METHODS: We applied a panel design with an interval of 2 weeks between T1 and T2 in general-population panel-participants (N = 310), assessing BECU and psychological distress related to somatic symptoms via validated self-report measures. Moreover, we cross-sectionally replicated the relationship between BECU and psychological distress in a clinical sample of psychosomatic outpatients diagnosed with somatoform disorders (n = 101) or without somatoform disorders (n = 628). RESULTS: BECU predicted over and above the lagged criterion panel-participants' psychological distress related to somatic symptoms, ß = -.18, p < .001. BECU was also cross-sectionally related to psychological distress in our clinical replication-sample of psychosomatic outpatients diagnosed with somatoform disorders, rS (87) = -.33, p = .002 and in those without, rS (557) = -.21, p < .001. CONCLUSIONS: BECU as a malleable way of thinking about emotions predicted psychological distress related to somatic symptoms in general-population panel-participants and correlated with the same in two clinical replication samples. BECU thus becomes a promising treatment target in psychotherapeutic approaches.

Improving data adequacy of ultrasonography reports for non-alcoholic fatty liver disease (NAFLD) through a national structured template.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a prevalent disorder that increases due to lifestyle, the rising rate of obesity, and population ages worldwide. Diagnostic ways, including sonography, do not have an explicit reporting structure. PURPOSE: To create a structure template for NAFLD reporting, investigate its completeness, and assess the specialist opinions of using it in clinical practice. MATERIAL AND METHODS: A structured reporting template (SRT) was designed and implemented in four stages. At first, important features were extracted from a comprehensive literature review and were evaluated by 10 radiologists and gastroenterologists using the Likert scale. Finally, the usefulness of the SRT in comparison with the conventional reporting template (CRT) was judged by 10 gastroenterologists completing the questionnaire. RESULTS: Demographic information and sonography of the liver, gallbladder, and spleen organs were the most critical features. The completeness scores of SRT reports were higher than CRT scores for almost all the factors studied. The difference in the scores was significant for most of the parameters. Moreover, the total completeness score increased from 42% in CRT to 92% in SRT. A comparison of the report adequacy of two reports was seen in all items. The SRT obtained more rates from specialists. CONCLUSION: Introduction of the SRT for NAFLD significantly enhanced the completeness of reporting to reduce variability in the interpretation of the related reports by clinicians. Nevertheless, more studies are needed to generalize the results in real scales for patients with NAFLD.

Continuous usage intention of mobile health services: model construction and validation.

BACKGROUND: Mobile health (mHealth) services can not give full play to their value if only it is used in the short term, and their continuous usage can achieve better effects in health management. This study aims to explore the factors that affect continuous usage intentions of mHealth services and their mechanism of action. METHODS: First, considering the uniqueness of health services and social environmental factors, this study constructed an extended Expectation Confirmation Model of Information System Continuance (ECM-ISC) to investigate factors that may influence the intention of continuous usage of mHealth services based on three dimensions, namely individual characteristics, technology and environment. Second, the survey method was used to validate the research model. The questionnaire items were derived from validated instruments and discussed by experts and data were collected both online and offline. The structural equation model was used for data analysis. RESULTS: There were 334 avidity questionnaires through cross-sectional data and these participants had used mHealth services ever. The reliability and validity of the test model were good, in which Cronbach's Alpha values of 9 variables exceeded 0.9, composite reliability 0.8, the average variance extracted value 0.5, and the factor loading 0.8. The modified model had a good fitting effect and strong explanatory power. It accounted for 89% of the variance in expectation confirmation, 74% of the variance in perceived usefulness, 92% of the variance in customer satisfaction, and 84% of the variance in continuous usage intention. Compared with the initial model hypotheses, perceived system quality was deleted according to the heterotrait-monotrait ratio, so paths related to it were deleted; perceived usefulness wasn't positively associated with customer satisfaction, and its path was also deleted. Other paths were consistent with the initial hypothesis. The two new added paths were that subjective norm was positively associated with perceived service quality (ß = 0.704, P < 0.001), and perceived information quality (ß = 0.606, P < 0.001). Electronic health literacy (E-health literacy) was positively associated with perceived usefulness (ß = 0.379, P < 0.001), perceived service quality (ß = 0.200, P < 0.001), and perceived information quality (ß = 0.320, P < 0.001). Continuous usage intention was influenced by perceived usefulness (ß = 0.191, P < 0.001), customer satisfaction (ß = 0.453, P < 0.001), and subjective norm (ß = 0.372, P < 0.001). CONCLUSIONS: The study constructed a new theoretical model including E-health literacy, subjective norm and technology qualities to clarify continuous usage intention of mHealth services, and empirically validated the model. Attention should be paid to E-health literacy, subjective norm, perceived information quality, and perceived service quality to improve continuous usage intention of users and self-management by mHealth Apps managers and governments. This research provides solid evidence for the validity of the expanded model of ECM-ISC in the mHealth field, which can be a theoretical and practical basis for mHealth operators' product research and development.

The influence of organizational factors on the acceptance of online teaching among college faculty during the COVID-19 pandemic: a nationwide study in mainland China.

The outbreak of the coronavirus disease 2019 (COVID-19) promoted online teaching on an unprecedented scale, raising researchers' attention to the importance of faculty's acceptance of this urgent teaching shift. This study aimed to explore the influence of organizational factors on faculty's acceptance of online teaching in terms of behavioral intention and perceived usefulness. A multilevel structural equation model was employed to analyze data on 209,058 faculty in 858 higher education institutions based on a nationwide survey conducted in mainland China. The results showed that three key organizational factors, namely strategic planning, leadership, and teaching quality monitoring, impacted faculty's acceptance of online teaching, although in different ways. Strategic planning had a direct impact on perceived usefulness, while leadership had a direct impact on behavioral intentions, and teaching quality monitoring had a direct impact on both perceived usefulness and behavioral intentions. In addition, an indirect effect was found between strategic planning and faculty's behavioral intentions through the mediation of the perceived usefulness of online teaching. The findings of this study have practical implications for college administrators and policymakers, which should effectively implement and promote online teaching and learning, and consider key organizational factors to increase faculty acceptance.

Links between ease of use, perceived usefulness and attitudes towards technology in older people in university: A structural equation modelling approach.

Technological resources have the potential to improve the quality of life in a context in which social pressure for the use of these tools is increasing. In this sense, the adoption of technological resources by the elderly is a highly complex issue because numerous and varied factors are involved. Precisely for this reason, this study aims to analyze the effects that exist between a series of dimensions related to the perception of older people regarding the ease of use, the perceived usefulness of technological tools, attitudes towards technology and their intention to use them in everyday life. To do this, 415 adults (M = 66.27 years) enrolled in a program at the University of Experience in the Spanish context completed an online questionnaire. The application of a Structural Equations Model for data analysis highlights that the perceived ease of use of the technology has a positive effect on the perceived usefulness of these resources. Similarly, an indirect effect of the perceived usefulness of technology on the intention to use these resources is observed through the manifestation of positive attitudes towards the use of digital tools.

Students' continuance intention to use MOOCs: empirical evidence from India.

In recent years, there has been an increasing interest in understanding the Massive open online courses (MOOCs) due to its gaining popularity. Even though the number of online platforms and programs has grown during the COVID-19 pandemic, there is still a high rate of dropout and non-completion. In this work, the expectation-confirmation model is combined with MOOC features such as perceived openness, perceived reputation, and other factors i.e., perceived enjoyment, and perceived computer self-efficacy to investigate the learner's continued intention to use MOOC. A survey was undertaken and the data was collected from 383 students pursuing their degrees (undergraduate and post-graduate) in Karnataka state, India. The collected data were analyzed with structural equation modelling in Smart PLS 3. The study confirms a significant influence of confirmation and perceived usefulness on satisfaction, and direct significant influence of perceived computer self-efficacy, satisfaction, and perceived usefulness on continuance intention. Also, the results demonstrated the significant influence of confirmation on perceived enjoyment and usefulness and the effect of computer self-efficacy on usefulness. The findings in this study indicate that the MOOC platforms should focus on confirming learner expectations and the usefulness of courses to ensure student satisfaction and continuance of courses.

An investigation of the social influence processes of flipped class students: An application of the extension of the technology acceptance model.

Universities are increasingly incorporating flipped learning as an effective instructional approach. Given the popularity of flipped learning, numerous studies have examined the psychological aspects of students and learning achievement in flipped learning classes. However, little research has examined the social influence processes of students in flipped class. This study investigated the effects of social influence processes (i.e., subjective norm, image, and voluntariness) on students' perceived usefulness of and intention to register for flipped learning using the extension of technology acceptance model (TAM2). A total of 306 undergraduates who took flipped classes participated in this research. The primary research findings indicated that subjective norm influenced perceived usefulness and intention to register for flipped classes. However, image did not influence perceived usefulness or intention to register for flipped classes. Voluntariness affected perceived usefulness and influenced intention to register for flipped classes through perceived usefulness.

Exploring non-linear relationships between perceived interactivity or interface design and acceptance of collaborative web-based learning.

The novelty of this study is in developing a conceptual model for predicting the non-linear relationships between human-computer interaction factors and ease of use and usefulness of collaborative web-based learning or e-learning. Ten models (logarithmic, inverse, quadratic, cubic, compound, power, s-curve, growth, exponential, and logistic) were examined as functions of effects compared to linear relationships to see which was the most appropriate, based on R2, adjusted R2 and SEE values. To answer the addressed questions, the researcher surveyed 103 students from Kadir Has University about the perceived interface and interactivity of e-learning. The results show that most of the hypotheses formulated for this purpose have been proven. Our analysis shows that cubic models (the relationship between ease of use and usefulness, visual design, course environment, learner-interface interactivity, and course evaluation system and ease of use), quadratic models (the relationship between visual design, and system quality and usefulness, course structure and content, course environment, and system quality and ease of use), logarithmic model (the relationship between course evaluation system and usefulness), and s-curve models (learner-interface interactivity, navigation, and course structure and content and usefulness) performed better in the description for the correlations. Supplementary Information: The online version contains supplementary material available at 10.1007/s10639-023-11635-6.

Impact of teacher-student interaction on students' classroom well-being under online education environment.

The students' classroom well-being of college students has been widely concerned in online education researches. In order to implement effectively online education in colleges and universities, based on person-context interaction theory, this study investigates a theoretical model of the impact of teacher-student interaction, sound richness, sound pleasure, perceived ease of use and perceived usefulness on students' classroom well-being. By surveying 349 college students receiving online education, the research hypotheses are tested by the structural equation model approach. Research results show that: teacher-student interaction, sound richness, sound pleasure, perceived ease of use and perceived usefulness appreciably improve students' classroom well-being, the sound richness and the students' perceived ease of use can moderate the effect of teacher-student interaction on students' classroom well-being. Finally some pedagogical implications are discussed.
