RESUMO

This study aims to investigate the role of trust and website conversion in consumer responses to green product purchasing, with a new perspective through the lens of innovative website design's technology integration. To achieve this objective, an online survey was conducted with a sample of 384 consumers in Thailand. The results reveal that user trust in innovative website design are significant predictor website conversion in consumer responses to green product purchasing. Innovative website design's technology integration positively influences anticipated website usability and anticipated website quality requirements, which, in turn, enhances trust and leads to increased consumer conversion to green product purchasing. Moreover, anticipated website quality requirement acts as a partial mediator in the relationship between technology integration of innovative website design and user trust in innovative website design. The relationship between user trust in innovative website design and conversion of consumer response to green product purchase is notably strong (ß = 0.203, p-value = 0.014), with user trust accounting for roughly 57.1 % of the variability in consumer conversion (R2=0.571). This substantial link suggests that in the broader context, enhancing elements that build trust within a website's design is crucial as it influences over half of the consumer's decision-making process related to green product purchases. Essentially, for industries and markets centered around eco-friendly products, investing in strategies to bolster user trust in their digital platforms could significantly drive consumer response and engagement. These findings have important implications for marketers and website designers seeking to enhance their green product sales by developing innovative website designs that incorporate technological integration and build trust with consumers. Both markers and website designers can use these insights to optimize their website design strategies, leading to increased conversion rates.

RESUMO

OBJECTIVES: This study aimed to portray available information on cancer-related fatigue on German health care institution websites considering the idea of patient empowerment. METHODS: Based on website quality criteria, we developed a website-rating tool comprising 18 items. Descriptive analyses, a KruskalWallis test, and corresponding post hoc tests comparing rating sum scores between institution groups were performed. RESULTS: Websites of 283 systematically compiled health care institutions were included in the rating. Cancer-related fatigue was introduced on 21.9% and detailed information was provided on 27.9% of the websites. Information material was offered on 9.2% of the websites, while fatigue treatment offers were presented on 21.6% of the websites. The rating sum scores differed between institution groups (p < 0.001), with Comprehensive Cancer Centers scoring significantly higher than the others. CONCLUSION: The rating revealed an overall sparse provision of information, with fatigue being addressed on less than half of the websites. PRACTICE IMPLICATIONS: For patients who have access to at least one introduction about fatigue, institutions need to extend their websites. Patients could further be referred to external institutions or information booklets. The naming of contact persons may help linking patients to providers.

RESUMO

In today's digital era, health information, especially for conditions like dementia, is crucial. This study aims to develop an instrument, demenTia wEbsite measSurement insTrument (TEST), through four steps: identifying existing instruments, determining criteria, selecting and revising measurement statements, and validating the instrument from March to August 2020. Five health informatics experts used the content validity ratio (CVR) test for validation. Thirteen evaluators compared Fleiss Kappa and intraclass correlation coefficient (ICC) values across four dementia websites using TEST and another tool, DISCERN. TEST consists of seven criteria and 25 measurement statements focusing on content quality (relevance, credibility, currency) and user experience (accessibility, interactivity, attractiveness, privacy). CVR = 1 confirmed all statements as essential. The TEST demonstrated stronger consistency and assessor agreement compared to DISCERN, measured by Fleiss Kappa and ICC. Overall, it is a robust tool for reliable and user-friendly dementia resources, ensuring health holistic information accessibility.

RESUMO

Background: Adolescents and young adults with sickle cell disease (SCD) transitioning from pediatric to adult health care face a high-risk period associated with increased use of acute health care services and mortality. Although 59% of American citizens report using the internet for health care information, the quality of web-based, patient-facing resources regarding transition in SCD care has not been evaluated. Objective: This study aimed to evaluate the quality and readability of web-based health information on SCD, especially as it pertains to the transition to adulthood for inidividuals with SCD. The study also compared the readability and content scores of websites identified in 2018 to those from 2021 to assess any change in quality over time. Methods: Keywords representing phrases adolescents may use while searching for information on the internet regarding transition in SCD care, including "hydroxyurea" and "SCD transition," were identified. A web-based search using the keywords was conducted in July 2021 using Google, Yahoo, and Bing. The top 20 links from each search were collected. Duplicate websites, academic journals, and websites not related to SCD health care transition were excluded. Websites were categorized based on the source: health department, hospital or private clinician, professional society, and other websites. Websites were assessed using Health On the Net Foundation code of conduct (HONcode), Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FGL), Ensuring Quality Information for Patients (EQIP), and a novel SCD content checklist (SCDCC). EQIP and SCDCC scores range from 0- to 100. Each website was reviewed by 2 research assistants and assessed for interrater reliability. Descriptive statistics were calculated. Results: Of the 900 websites collected, 67 (7.4%) met the inclusion criteria: 13 health department, 7 hospital or private clinician, 33 professional society, and 14 other websites. A total of 15 (22%) out of 67 websites had HONcode certification. Websites with HONcode certification had higher FRE and EQIP scores and lower FGL scores than those without HONcode certification, reflecting greater readability. Websites without HONcode certification had higher SCDCC scores, reflecting greater clinical content. Only 7 (10%) websites met the National Institutes of Health recommendation of a seventh-grade or lower reading level. Based on EQIP scores, 6 (9%) websites were of high quality. The mean SCDCC score was 20.60 (SD 22.14) out of 100. The interrater reliability for EQIP and SCDCC ratings was good (intraclass correlation: 0.718 and 0.897, respectively). No source of website scored significantly higher mean EQIP, FRE, FGL, or SCDCC scores than the others (all P<.05). Conclusions: Although seeking health care information on the web is very common, the overall quality of information about transition in SCD care on the internet is poor. Changes to current web-based health care information regarding SCD care transitions would benefit transitioning youth by providing expectations, knowledge, skills, and tools to increase self-efficacy.

RESUMO

Improving the quality of electronic services (e-services) is essential when dealing with unforeseen factors and uncertainties in healthcare, such as the outbreak of coronavirus (COVID-19) and changes in the needs and expectations of patients. This paper presents a comprehensive conceptual model in healthcare systems for improving the user acceptance of e-services. A model referred to as the technology acceptance model (TAM) is considered that includes several factors. The factors are computer literacy, website quality, service quality, user attitude, perceived enjoyment, and user satisfaction. According to the collected data and the performed analysis, the fit indices of this survey reveal that the conceptual model has an acceptable fit. The findings are as follows. Computer literacy has positive effects on perceived enjoyment and ease of use. Website quality has positive effects on perceived enjoyment, ease of use, and user satisfaction. Perceived enjoyment has a positive effect on perceived usefulness. Ease of use has positive effects on the usefulness, willingness to use e-services, and user attitude. User satisfaction has a positive effect on user attitude. Perceived usefulness has a positive effect on the willingness to use e-services. Finally, among these variables, only the user attitude has no significant effect on the willingness to use e-services in the healthcare system. Therefore, to promote performance quality and to motivate people to use e-services, healthcare managers should improve these factors.

RESUMO

BACKGROUND: In the information era, patients can easily be misled by inaccurate internet content, thus making not well-informed decisions about medical issues. Adenoid hypertrophy, one of the most common causes of chronic upper airway obstruction in children and adolescents, may lead to serious complications, including sleep apnea and craniofacial change. There have been no critical studies about the quality of websites on adenoid hypertrophy, posing a challenge for users without a medical background to determine which website offers more reliable information. Moreover, the blockage of access to internet search tools such as Google, Yahoo, and others has created an isolated internet environment for the enormous user population in mainland China. Differences in internet legislation, the commercial environment, and culture are also likely to result in varied quality of online health information inside and outside mainland China. To date, no study has compared the quality difference between mainland Chinese and English websites. OBJECTIVE: The aims of this study were to (1) analyze the quality of websites about adenoid hypertrophy accessible by patients, (2) investigate the quality differences between Chinese and English websites, (3) determine which type of website (eg, government-sponsored, health care provider) is more reliable in terms of medical information, and (4) determine whether the blockage of foreign websites is hindering users' accessibility to better-quality websites in mainland China. METHODS: The first 100 websites (excluding advertisements) displayed on the top three search engines worldwide and in mainland China for the key search term "enlarged adenoids" were collected as the data source. The websites were evaluated based on accessibility, accountability, interactivity, structure, and content quality (accuracy, content coverage, and objectivity). Cohen κ was calculated, and one-way ANOVA and the Kruskal-Wallis test were performed to compare the results between groups and subgroups. RESULTS: The mean score for the content quality of English websites was significantly higher than that of Chinese websites (6.16 vs 4.94, P=.03 for Google, Bing, and Yahoo; 6.16 vs 4.16, P<.001 for Baidu, Sougou, and Bing China). Chinese users who are not influenced by the Internet Censorship System are more likely to access higher-quality online medical information (4.94 vs 4.16, P=.02). In within-group Student-Newman-Keuls q posthoc analysis, professional organization and government-sponsored websites were generally of better quality than other websites for both Chinese and English websites (P<.05). CONCLUSIONS: Generally, the English websites on adenoid hypertrophy are of better quality than Chinese websites; thus, Chinese users residing outside of the Chinese mainland are less influenced by inaccurate online medical information.

RESUMO

Recently, social media marketing has become one of the most significant growth channels for many businesses. However, many companies are still unclear about using social media marketing to their advantage, particularly in an e-commerce environment. In this background, this study examines the effect of website quality, consumer satisfaction, and eWOM on online purchase intention. An online survey was conducted with 789 online Chinese shoppers from four cities-Harbin, Shenyang, Guangzhou, and Shenzhen. Structural equation modeling (SEM) was used to analyze the hypotheses. The findings show that each variable had a high impact on eWOM with website quality (information quality, system quality, and service quality), which in turn positively increased consumer online purchase intentions in China's e-commerce business. Additionally, findings show a significant gender gap in online shopping behavior. This novel research provides several managerial guidelines that support managers in improving their business performance in the e-commerce industry. This research also highlighted some limitations.

RESUMO

The quality of healthcare service websites gains particular importance in the time of the pandemic, asthe popularity of electronic services grows. This applies to infectious disease hospitals as well, often on the front line of the effort against COVID-19. The paper aims to assess the quality of infectious disease hospital websites in Poland in light of the COVID-19 pandemic. The research covered 91 websites. The first stage was an analysis of selected technical attributes of the websites (including website performance, SEO quality, website availability, and mobile-friendliness) with selected online tools, such as Google PageSpeed Insights, Blink Audit Tool, Backlink Checker, andwebsite accessibility evaluation tool (WAVE). The data were then analyzed with statistical methods. The next step was to analyze the content of the websites. The research has shown that most of the websites were of satisfactory quality, apart from those that were not mobile-ready. The following keywords were found most often on the hospital websites: SARS-CoV-2, COVID-19, smear, specialist care clinic, isolation, telephone consultations, sample collection center, support, coronavirus, recommendations, patient registration, signs of disease. The research suggests that the quality of infectious disease hospital websites in Poland is significantly diversified in search engine optimization, mobile-friendliness, and needs of people at risk of digital exclusion.

RESUMO

BACKGROUND: In recent years, there has been an increase in the utilization of complementary and integrative health (CIH) care, and an increase in information-seeking behavior focused on CIH. Thus, understanding the quality of CIH information that is available on the internet is imperative. Although there have been a limited number of studies evaluating the quality of websites providing information about specific CIH-related topics, a broad evaluation of CIH websites has not been conducted. OBJECTIVE: This study was designed to fill that gap. We set out to assess website quality in 5 CIH domains: (1) acupuncture, (2) homeopathy, (3) massage, (4) reiki, and (5) yoga. This study aimed to 1) characterize the websites by type and quality; 2) evaluate website characteristics which may affect readers' perceptions, specifically message content, structural features, and presentation style, and 3) investigate the extent to which harms, benefits and purposes of use are stated on websites. METHODS: This study employed a systematic search strategy to identify websites in each of the target domains to be evaluated. The websites were then classified by type, and a set of checklists focusing on quality, message content, structural features, and presentation style was used to evaluate the websites. Lastly, we performed content analysis to identify harms, benefits, and perceived purposes of use. RESULTS: There were similarities across domains regarding their overall quality and their message content. Across all domains, a high proportion of websites received strong scores in terms of ownership, currency, interactivity and navigability. Scores were more variable concerning authorship, balanced presentation of information and the use of sources of information. However, there were differences regarding their structural features and presentation style. Acupuncture and reiki sites tended to include more external links, and yoga, fewer. There was variation across domains in the extent to which the websites contained domain-specific terminology. Websites tended to provide an extensive list of potential benefits, while reporting of harms was scarce. CONCLUSIONS: This is the first study to perform a multidimensional assessment of websites in multiple CIH domains. This review showed that while there are similarities among websites of different CIH domains, there are also differences. The diverse distribution of website types suggests that, regardless of CIH domain, the public encounters information through many different types of media, and it would be useful to consider how the presentation of this content may differ depending on the medium. The characteristics for which variability exist are areas that warrant greater attention from researchers, policy makers, clinicians and patients. There is also a need to better understand how individuals may interact with CIH websites, and to develop tools to assist people to interpret the CIH-related information that they encounter.

RESUMO

BACKGROUND: Websites on which users can rate their physician are becoming increasingly popular, but little is known about the website quality, the information content, and the tools they offer users to assess physicians. This study assesses these aspects on physician-rating websites in German- and English-speaking countries. OBJECTIVE: The objective of this study was to collect information on websites with a physician rating or review tool in 12 countries in terms of metadata, website quality (transparency, privacy and freedom of speech of physicians and patients, check mechanisms for appropriateness and accuracy of reviews, and ease of page navigation), professional information about the physician, rating scales and tools, as well as traffic rank. METHODS: A systematic Web search based on a set of predefined keywords was conducted on Google, Bing, and Yahoo in August 2016. A final sample of 143 physician-rating websites was analyzed and coded for metadata, quality, information content, and the physician-rating tools. RESULTS: The majority of websites were registered in the United States (40/143) or Germany (25/143). The vast majority were commercially owned (120/143, 83.9%), and 69.9% (100/143) displayed some form of physician advertisement. Overall, information content (mean 9.95/25) as well as quality were low (mean 18.67/47). Websites registered in the United Kingdom obtained the highest quality scores (mean 26.50/47), followed by Australian websites (mean 21.50/47). In terms of rating tools, physician-rating websites were most frequently asking users to score overall performance, punctuality, or wait time in practice. CONCLUSIONS: This study evidences that websites that provide physician rating should improve and communicate their quality standards, especially in terms of physician and user protection, as well as transparency. In addition, given that quality standards on physician-rating websites are low overall, the development of transparent guidelines is required. Furthermore, attention should be paid to the financial goals that the majority of physician-rating websites, especially the ones that are commercially owned, pursue.

RESUMO

OBJECTIVE: the aim of this study is to evaluate the quality of web pages found by women when carrying out an exploratory search concerning pregnancy, childbirth, the postpartum period and breastfeeding. DESIGN/SETTING: a descriptive study of the first 25 web pages that appear in the search engines Google, Yahoo and Bing, in October 2014 in the Basque Country (Spain), when entering eight Spanish words and seven English words related to pregnancy, childbirth, the postpartum period, breastfeeding and newborns. Web pages aimed at healthcare professionals and forums were excluded. The reliability was evaluated using the LIDA questionnaire, and the contents of the web pages with the highest scores were then described. FINDINGS: a total of 126 web pages were found using the key search words. Of these, 14 scored in the top 30% for reliability. The content analysis of these found that the mean score for "references to the source of the information" was 3.4 (SD: 2.17), that for "up-to-date" was 4.30 (SD: 1.97) and the score for "conflict of interest statement" was 5.90 (SD: 2.16). The mean for web pages created by universities and official bodies was 13.64 (SD: 4.47), whereas the mean for those created by private bodies was 11.23 (SD: 4.51) (F (1,124)5.27. p=0.02). The content analysis of these web pages found that the most commonly discussed topic was breastfeeding, followed by self-care during pregnancy and the onset of childbirth. CONCLUSION: in this study, web pages from established healthcare or academic institutions were found to contain the most reliable information. The significant number of web pages found in this study with poor quality information indicates the need for healthcare professionals to guide women when sourcing information online. As the origin of the web page has a direct effect on reliability, the involvement of healthcare professionals in the use, counselling and generation of new technologies as an intervention tool is increasingly essential.

RESUMO

BACKGROUND: While the internet is considered a promising avenue for providing physical activity support to prostate cancer survivors, little is known about the accessibility of quality websites in the real world. PURPOSE: This work aimed to explore what websites prostate cancer survivors are likely to find when seeking physical activity support online and to evaluate their quality using evidenced-based criteria. METHOD: A search strategy was developed in consultation with prostate cancer survivors (n = 44) to reflect the most common ways they are likely to search the internet. The search was then conducted by a single reviewer, and identified websites were assessed for quality by two reviewers using an evidence-based quality assessment tool developed for this study. Discrepancies were resolved by a third reviewer. RESULTS: Of the 45 identified websites, 13 (29%) received a high quality rating, 22 (49%) received a moderate rating and 10 (22%) received a low quality rating. Higher-quality websites tended to have a .org or .gov domain and tended to be located using searches specific to prostate cancer or prostate cancer and exercise. Very few websites contained complete information regarding the physical activity guidelines for cancer survivors, and no websites provided comprehensive behaviour change support. CONCLUSION: There are some good-quality physical activity websites accessible to men with prostate cancer. However, they may be difficult to find and/or require updating to include complete recommendations and more behaviour change support. IMPLICATIONS FOR CANCER SURVIVORS: Efforts to improve physical activity information online and strategies to direct prostate cancer survivors to higher-quality websites and support services are needed to ensure safety and efficacy.

RESUMO

This study investigated the cognitive structure of sport website quality constructs by comparing a bifactor model (a.k.a., a general-specific model) to a second-order model. The models are two alternative approaches for representing general constructs consisting of several highly related but distinct domains. In addition, the link between sport website quality and the revisitation and media consumption intentions was empirically tested. Data ( N = 272) were collected through an online survey, and the majority of respondents were men (66.3%) between 21 and 30 years old (63.0%). The bifactor and second-order models of sport website quality were also assessed and compared, and a simultaneous equation modeling analysis was used. The bifactor model fit the data significantly better than the second-order model, indicating that the five sub-constructs revealed both the specific dimensions of sport website quality and the holistic nature of sport website quality. Results from the simultaneous equation model indicated that sport website quality explained 70.2% of the variance in revisitation and 58.7% of intention to consume sports media.

RESUMO

BACKGROUND: The Internet is a frequently accessed source of information for parents of a child with autism. To help parents make informed decisions about treatment options, websites should contain accurate information. This study aimed to evaluate the quality of information in a sample of autism-relevant websites. MATERIALS AND METHODS: Autism-related keywords were entered into three widely used search engines in April 2013 and the 20 most frequently appearing sites identified. Website quality was rated, by two independent raters, using the DISCERN tool. Websites were also coded according to the type of references/sources provided to support the intervention content presented. RESULTS: The mean DISCERN score was 46.5 (range 23-67.5), of a possible 80. Information about treatment risks and no treatment as an option was rarely described. Only six (30%) websites provided research references when describing intervention options. CONCLUSIONS: Many websites did not meet criteria for quality health information and failed to cite evidence supporting described interventions. Implications of these findings are discussed.

RESUMO

The Internet is commonly used to seek health-related information, but little is known about the quality of websites on developmental disabilities. Therefore, we sought to evaluate the characteristics and quality of websites located by searching ten common terms related to developmental disabilities and explore relations between website characteristics and website quality in order to make recommendations on ways to ensure locating good online information. We located 208 unique websites in our November 2012 US searches of Google and Bing. Two independent coders evaluated 10 characteristics of the websites and two different coders assessed the quality of the websites. From the 208 websites, 104 (50%) provided relevant information about the disability being searched. Of these 104 websites, those found to be of highest quality were least likely to be a sponsored result, contain advertisements, be from a for-profit company, and did contain references to peer-reviewed publications or had a top-level domain of .gov or .org. Individuals with developmental disabilities and their family members who choose to obtain disability-related information online should remain vigilant to ensure that they locate high-quality and accurate information and should not replace information obtained from health-care professionals and educational specialists with information found online.

RESUMO

BACKGROUND: Celiac disease is an autoimmune disease that affects approximately 1% of the US population. Disease is characterized by damage to the small intestinal lining and malabsorption of nutrients. Celiac disease is activated in genetically susceptible individuals by dietary exposure to gluten in wheat and gluten-like proteins in rye and barley. Symptoms are diverse and include gastrointestinal and extraintestinal manifestations. Treatment requires strict adherence to a gluten-free diet. The Internet is a major source of health information about celiac disease. Nonetheless, information about celiac disease that is available on various websites often is questioned by patients and other health care professionals regarding its reliability and content. OBJECTIVES: To determine the accuracy, comprehensiveness, transparency, and readability of information on 100 of the most widely accessed websites that provide information on celiac disease. METHODS: Using the search term celiac disease, we analyzed 100 of the top English-language websites published by academic, commercial, nonprofit, and other professional (nonacademic) sources for accuracy, comprehensiveness, transparency, and reading grade level. Each site was assessed independently by 3 reviewers. Website accuracy and comprehensiveness were probed independently using a set of objective core information about celiac disease. We used 19 general criteria to assess website transparency. Website readability was determined by the Flesch-Kincaid reading grade level. Results for each parameter were analyzed independently. In addition, we weighted and combined parameters to generate an overall score, termed website quality. RESULTS: We included 98 websites in the final analysis. Of these, 47 (48%) provided specific information about celiac disease that was less than 95% accurate (ie, the predetermined cut-off considered a minimum acceptable level of accuracy). Independent of whether the information posted was accurate, 51 of 98 (52%) websites contained less than 50% of the core celiac disease information that was considered important for inclusion on websites that provide general information about celiac disease. Academic websites were significantly less transparent (P = .005) than commercial websites in attributing authorship, timeliness of information, sources of information, and other important disclosures. The type of website publisher did not predict website accuracy, comprehensiveness, or overall website quality. Only 4 of 98 (4%) websites achieved an overall quality score of 80 or above, which a priori was set as the minimum score for a website to be judged trustworthy and reliable. CONCLUSIONS: The information on many websites addressing celiac disease was not sufficiently accurate, comprehensive, and transparent, or presented at an appropriate reading grade level, to be considered sufficiently trustworthy and reliable for patients, health care providers, celiac disease support groups, and the general public. This has the potential to adversely affect decision making about important aspects of celiac disease, including its appropriate and proper diagnosis, treatment, and management.
