Introduction: Proficient use of technology requires many intersecting skills including literacy, citizenship, advocacy, self-determination, and digital competence. In this study, the authors engaged experts in the field of visual impairment in focus groups with the purpose of defining digital competence, discussing issues related to visual impairment, identifying specific skills, and organizing technology competencies. Methods: Purposeful sampling was used to recruit 32 assistive technology and literacy experts in the field of visual impairment to participate in a series of focus groups. Each focus group was presented with four main topics (1) defining digital competence, (2) identifying specific considerations for individuals with visual impairments (i.e., those who are blind or have low vision), (3) forming a list of technology competencies, and (4) categorizing competencies into an organized structure. Within-group consensus and across-group data saturation were achieved after nine focus groups were conducted via teleconferencing. Results: Focus groups led to three significant findings. First, the consensus was reached by participants on the definition of digital competence. Second, participants agreed upon considerations for individuals with visual impairments. Third, a set of 41 competencies was created. A consensus was not reached on categorizing the competencies. However, several themes arose including the need to address problem solving, accessibility, self-advocacy, citizenship, and self-determination, in addition to technology skills. Discussion: Authors concluded the study by presenting a framework for digital competence that may be used to guide future research. Implications for Practitioners: Students’ success in digital learning environments is predicated on skills that extend beyond device usage. In addition to using digital tools efficiently and effectively, instruction should include opportunities for self-determination, access, problem solving, critical thinking, citizenship, and advocacy.
简介:熟练使用技术需要许多交叉技能,包括识字、公民身份、宣传、自决和数字能力。在这项研究中,作者让视觉障碍领域的专家参加焦点小组,目的是定义数字能力,讨论与视觉障碍相关的问题,确定特定技能,并组织技术能力。方法:采用有目的的抽样方法,招募32名视觉障碍领域的辅助技术和识字专家参加一系列焦点小组。每个焦点小组都有四个主要主题:(1)定义数字能力,(2)确定视觉障碍者(即盲人或低视力者)的具体考虑因素,(3)形成技术能力列表,以及(4)将能力分类为一个有组织的结构。在通过电话会议进行了九个重点小组讨论后,小组内部和小组间的数据饱和。结果:焦点小组得出了三个重要的发现。首先,与会者就数字能力的定义达成了共识。其次,参与者就视觉障碍患者的考虑因素达成一致。第三,建立了一套41项能力。未能就能力分类达成共识。然而,出现了几个主题,包括需要解决问题、无障碍、自我宣传、公民身份和自决,以及技术技能。讨论:作者在研究结束时提出了一个数字能力框架,可用于指导未来的研究。对从业者的启示:学生在数字学习环境中的成功取决于超越设备使用的技能。除了高效和有效地使用数字工具外,教学还应包括自决、获取、解决问题、批判性思维、公民身份和倡导的机会。

Introduction: This article covers the technical development and usability testing of 4to24, a mobile application (app) for students with visual impairments and their parents. The app includes information and resources on numerous topics to support and encourage preparation for employment from an early age. Methods: We partnered with technical developers from the blindness field to design and develop the app using an iterative approach that included usability testing at two key points in the development process. Technical developers incorporated accessibility into the app's design as it was built. Researchers conducted two rounds of usability testing with a total of 9 parents and 10 students. Participants completed specific tasks in the app and completed the System Usability Scale (SUS) to assess the app's usability. Results: Mean SUS scores were 80.83 for Round 1 and 83.75 for Round 2, indicating above-average usability at both time points. In each round, participants provided feedback on the app interface and identified issues impacting the app's ease of use. Discussion: We devised a system that automatically sends relevant informational modules to users based on the student's age, grade level, experience, and progress. The iterative design process allowed us to seek user feedback through usability testing and correct identified issues as development progressed, resulting in an intuitive and easy-to-use app. We also assessed and corrected accessibility issues as they arose, ensuring that the app met users’ accessibility needs. Implications for Practitioners: 4to24 is a usable and accessible mobile app that provides parents and students with relevant, timely information and resources to help students prepare for employment as they grow.

The United Nations and most governments around the world committed to sustainable development goals in 2015. The 17 sustainable development goals and 169 targets aspire to bring far-reaching global changes in the field of economics, health, education, inequality, social, and environmental issues. The sustainable development goals are integrated, which means that an action in one area will bring the change in another. The third sustainable development goal (good health and well-being) aims to achieve universal health coverage through its interlinking with other goals (United Nations, 2015). Improving access to affordable and clean energy, the seventh sustainable development goal is fundamentally tied to the third. Owing to its potential to affect health services, the World Health Organization (WHO) emphasized that electricity or power is an enabling factor for universal health care access (World Health Organization, 2014). It is important to link access to energy or power to health outcomes. The availability of electricity and its interaction with the health care system is an important determinant in providing and receiving health care information and services (Devasenapathy et al., 2016). The availability of electricity that provides continuous hours of supply and stable voltage has a direct impact on health outcomes (World Health Organization, 2014). The Indian state of Punjab has been reeling under acute electricity shortage due to limited electricity generation and distribution caused by depleting coal supplies (Kannappan, 2021; Vasdev, 2021). A high number of power shortages have been reported in the state in 2021 and 2022, leaving Punjab in an acute electricity crisis (Kannappan, 2021; Vasdev, 2021). While the health sector is no exception in being affected by power outages, these have significant consequences in the accessibility of health care and affect the delivery of continuous services. Meanwhile, traditional power sources mitigate the power demands in resource-poor settings to ensure continuity of services (Klinger, Landeg, & Murray, 2014). The Indian Public Health Standard (IPHS) lists out the essential medical equipment that is necessary to deliver quality healthcare in a public health setting. Most of the essential medical equipment is dependent on electricity. The lack of availability of and nonfunctional equipment could subsequently hamper delivery of health services, in settings that have limited resources (Mani, Patnaik, & Dholakia, 2019). Diabetic retinopathy is a complication of diabetes that can cause vision loss and visual
2015年,联合国和世界上大多数国家政府都致力于实现可持续发展目标。17个可持续发展目标和169个具体目标渴望在经济、卫生、教育、不平等、社会和环境问题领域带来深远的全球变化。可持续发展目标是一体化的,这意味着一个领域的行动将带来另一个领域。第三个可持续发展目标(良好健康和福祉)旨在通过与其他目标的相互联系实现全民健康覆盖(联合国,2015年)。改善获得负担得起的清洁能源的机会,第七个可持续发展目标与第三个目标有着根本的联系。鉴于电力可能影响卫生服务,世界卫生组织(世界卫生组织)强调,电力是普及卫生保健的有利因素(世界卫生组织,2014年)。将获得能源或电力与健康结果联系起来很重要。电力的可用性及其与医疗保健系统的相互作用是提供和接受医疗保健信息和服务的重要决定因素(Devasenpathy等人,2016)。提供连续供电时间和稳定电压的电力供应对健康结果有直接影响(世界卫生组织,2014)。由于煤炭供应耗尽导致发电和配电有限,印度旁遮普邦一直处于严重的电力短缺之下(Kannappan,2021;Vasdev,2021)。据报道,2021年和2022年,该州出现了大量电力短缺,使旁遮普陷入严重的电力危机(Kannappan,2021;Vasdev,2021)。虽然卫生部门也不例外受到停电的影响,但停电对医疗保健的可及性产生了重大影响,并影响了持续服务的提供。同时,传统电源缓解了资源匮乏环境中的电力需求,以确保服务的连续性(Klinger,Landeg,&Murray,2014)。印度公共卫生标准(IPHS)列出了在公共卫生环境中提供高质量医疗保健所需的基本医疗设备。大多数基本医疗设备都依赖电力。在资源有限的环境中,缺乏可用性和无法正常工作的设备可能会阻碍卫生服务的提供(Mani,Patnaik,&Dholakia,2019)。糖尿病视网膜病变是糖尿病的一种并发症,可导致视力下降和视力下降

Introduction: The COVID-19 pandemic has affected access to health and social services globally, leading to delays in accessing appropriate care. However, while there is a growing base of research into service access for the general population, there remains scarce information on the implications of the pandemic on disabled people. This article describes issues with health and disability support access for people with impaired vision in Aotearoa New Zealand (Aotearoa). Methods: Applying an Interpretive Description methodology, 62 interviews were conducted with disabled people; 10 of these individuals identified as having impaired vision. Findings were analyzed thematically for the entire group of 62, representing varied impairment groups, and then for the 10 who had impaired vision. Results: Five key themes arose from the interviews, including transportation difficulties, mental distress, loss of community, loss of physical contact and signals, and general loss of support. Participants identified that this loss of support occurred at multiple levels, meaning that the disability and healthcare system as a whole was ill-equipped to manage their needs. Participants reported a lag-time in accessing care, meaning that the effects of the pandemic are still felt due to a lack of available support and resources. Discussion: This article remains one of a few studies to look at the implications of the pandemic on access to health and disability services for those with impaired vision. It highlights that despite Aotearoa's good track record in managing the pandemic, groups were forgotten and marginalized by the collective response to managing COVID-19. Implications for Practitioners: Blindness professionals must be aware of the possible disadvantages and impacts of pandemics and other disasters on people with impaired vision and their access to health and disability services. Policymakers must include disabled people at the decision-making table so that the diverse needs of these populations are managed.

导言:COVID-19 大流行影响了全球范围内医疗和社会服务的获取,导致人们无法及时获得适当的医疗服务。然而,尽管对普通人群获得服务情况的研究越来越多,但有关大流行病对残疾人影响的信息仍然很少。本文介绍了新西兰奥特亚罗瓦(Aotearoa)视力受损者在获得医疗和残疾支持方面遇到的问题。方法:采用解释性描述方法,对残疾人进行了 62 次访谈,其中 10 人被确认为视力受损。我们对代表不同障碍群体的整个 62 人小组的调查结果进行了专题分析,然后对 10 名视力受损者的调查结果进行了专题分析。结果:访谈产生了五个关键主题,包括交通困难、精神痛苦、失去社区、失去身体接触和信号,以及普遍失去支持。参与者发现,这种失去支持的情况发生在多个层面,这意味着整个残疾和医疗系统没有能力满足他们的需求。与会者报告了获得护理的滞后情况,这意味着由于缺乏可用的支持和资源,他们仍能感受到大流行病的影响。讨论:这篇文章是为数不多的研究之一,研究了大流行对视力受损者获得医疗和残疾服务的影响。文章强调,尽管奥特亚罗瓦在管理大流行病方面有着良好的记录,但在管理 COVID-19 的集体应对措施中,一些群体被遗忘和边缘化了。对从业人员的启示:防盲专业人员必须意识到大流行病和其他灾难对视力受损者可能造成的不利影响,以及他们获得医疗和残疾服务的机会。政策制定者必须让残疾人参与决策,以便满足这些人群的不同需求。

Digging into p Values 挖掘p值

R. W. Emerson
Back in the January to February 2016 issue of this journal, I discussed p value and the increased need to report effect sizes along with p value. Since some time has passed and p value remains an important aspect of statistical reporting, I thought it wise to revisit the topic. To illustrate some points, we will refer to the article from this issue entitled “COVID-19: Social Distancing and Physical Activity in United Kingdom Residents with Visual Impairment,” by Strongman, Swain, Chung, Merzbach, and Gordon. The authors of this article made a number of t test comparisons where they are comparing the mean of one group to the mean of another group. If you cast your mind back, you will remember that, in the social sciences, we generally have a cutoff for “statistical significance” of .05 for such comparisons. This measure of significance means that, if the p value or significance level, is < .05, the difference in means between the two groups is deemed “statistically significant.” Statistical significance means that there is less than a 5% chance that the observed difference is due to chance. It is the accepted level of chance that experimenters are willing to accept in the social sciences, where data tend to be a little more noisy or hard to measure accurately than in something like physics. Let us unpack this matter a little more. A number of the comparisons in the article I am using as an example today has p values close to .05, either slightly more or less. How meaningful is it to claim that a comparison with a p value of .051 is not statistically meaningful while one with a p value of .049 is? This question is the reason why I made the case in 2016 that we should also include a measure of effect size when reporting the results of statistical tests so that the magnitude of the difference can also be known. In 1994, Jacob Cohen, a big name in statistics circles, wrote a piece entitled, “The Earth is Round (p < .05),” in which he summarized a long history of people noting that null hypothesis significance testing (which is what you are doing when you rely on the p level) is a dangerous game. Let us take this suggestion step by step. In null hypothesis significance testing (or NHST, for short), we start with the null hypothesis that the groups we are comparing are not different, or are drawn from the same larger population. If the p value from our statistical comparison is less than our cutoff (which is often .05), we “fail to accept the null hypothesis,” which leads one to want to say that the two groups are different. As Jacob Cohen notes,
早在2016年1月至2月的这期杂志上,我就讨论了p值以及随着p值的增加而报告效应大小的需求。由于一段时间过去了,p值仍然是统计报告的一个重要方面,我认为重新讨论这个话题是明智的。为了说明一些观点,我们将参考本期Strongman、Swain、Chung、Merzbach和Gordon撰写的题为“新冠肺炎:英国视力障碍居民的社交距离和身体活动”的文章。这篇文章的作者进行了一些t检验比较,他们将一组的平均值与另一组的均值进行比较。如果你回想一下,你会记得,在社会科学中,这种比较的“统计显著性”通常为0.05。这种显著性度量意味着,如果p值或显著性水平<.05,则两组之间的平均值差异被视为“统计学显著性”。统计学显著性意味着观察到的差异由偶然性引起的可能性不到5%。这是实验者在社会科学中愿意接受的可接受的机会水平,在社会科学领域,数据往往比物理学等学科的数据更嘈杂或更难准确测量。让我们再深入探讨一下这件事。我今天以文章中的一些比较为例,其p值接近.05,或者略高或者略低。声称p值为.051的比较在统计上没有意义,而p值为.049的比较在统计学上有意义,这有多大意义?这个问题就是我在2016年提出的理由,即在报告统计测试结果时,我们还应该包括效应大小的衡量标准,这样就可以知道差异的大小。1994年,统计学界的大人物雅各布·科恩写了一篇题为《地球是圆的(p<0.05)》的文章,他在文章中总结了长期以来人们注意到零假设显著性检验(即当你依赖p水平时所做的)是一种危险的游戏。让我们逐步采纳这个建议。在零假设显著性检验(简称NHST)中,我们从零假设开始,即我们比较的群体没有差异,或者来自同一个更大的群体。如果我们统计比较的p值小于我们的截止值(通常为.05),我们“无法接受零假设”,这会导致人们想说这两组人不同。正如Jacob Cohen所指出的,

Emerson","doi":"10.1177/0145482x221144443","DOIUrl":"https://doi.org/10.1177/0145482x221144443","url":null,"abstract":"Back in the January to February 2016 issue of this journal, I discussed p value and the increased need to report effect sizes along with p value. Since some time has passed and p value remains an important aspect of statistical reporting, I thought it wise to revisit the topic. To illustrate some points, we will refer to the article from this issue entitled “COVID-19: Social Distancing and Physical Activity in United Kingdom Residents with Visual Impairment,” by Strongman, Swain, Chung, Merzbach, and Gordon. The authors of this article made a number of t test comparisons where they are comparing the mean of one group to the mean of another group. If you cast your mind back, you will remember that, in the social sciences, we generally have a cutoff for “statistical significance” of .05 for such comparisons. This measure of significance means that, if the p value or significance level, is < .05, the difference in means between the two groups is deemed “statistically significant.” Statistical significance means that there is less than a 5% chance that the observed difference is due to chance. It is the accepted level of chance that experimenters are willing to accept in the social sciences, where data tend to be a little more noisy or hard to measure accurately than in something like physics. Let us unpack this matter a little more. A number of the comparisons in the article I am using as an example today has p values close to .05, either slightly more or less. How meaningful is it to claim that a comparison with a p value of .051 is not statistically meaningful while one with a p value of .049 is? This question is the reason why I made the case in 2016 that we should also include a measure of effect size when reporting the results of statistical tests so that the magnitude of the difference can also be known. In 1994, Jacob Cohen, a big name in statistics circles, wrote a piece entitled, “The Earth is Round (p < .05),” in which he summarized a long history of people noting that null hypothesis significance testing (which is what you are doing when you rely on the p level) is a dangerous game. Let us take this suggestion step by step. In null hypothesis significance testing (or NHST, for short), we start with the null hypothesis that the groups we are comparing are not different, or are drawn from the same larger population. If the p value from our statistical comparison is less than our cutoff (which is often .05), we “fail to accept the null hypothesis,” which leads one to want to say that the two groups are different.

Introduction: The introduction of the COVID-19 lockdown and social distancing policy has the potential to restrict access to physical activity, change exercise behavior, and to increase sedentary behavior. This study was conducted with the support of British Blind Sport and evaluates the effect of the lockdown policy on adults with visual impairments in the United Kingdom (UK). Methods: An online survey based on the World Health Organization's Global Physical Activity Questionnaire was completed by 73 participants (median age 35-44 years, 59% female) to gain information on how the implementation of the lockdown policy by the UK government has affected physical activity and sedentary behavior in adults that are visually impaired. Paired sample t-tests and Wilcoxon signed rank tests were used to analyze continuous and Likert scale data, respectively. Results: The majority of participants continued to exercise during lockdown, but the nature of this activity altered with a significant change to exercising in a private indoor space (+190% (always), z = -3.871, p < 0.001), and those exercising alone (+118% (always), z = -2.595, p = 0.009). The volume of activity reduced in all cases, between -11% and -52%, with significant changes in duration of vigorous day-to-day activity, moderate day-to-day activity, travel by foot or cycle, and vigorous recreational activity. Sedentary behavior increased on average by 21% (t(59) = -2.050, p = 0.045), with a greater effect seen in females (+36%, t(35) = -2.525, p = 0.016). Discussion: Reductions in physical activity volume and increases in sedentary behavior are consequences of the UK lockdown for those with visual impairments. The health and well-being implications of these data to this specific population are of particular concern. Implications for Practitioners: Lockdown measures should be designed with consideration of the needs of people with disabilities. Innovative ways to engage these populations in physical activity are strongly encouraged.

简介:新冠肺炎封锁和保持社交距离政策的出台有可能限制人们进行体育活动,改变锻炼行为,并增加久坐行为。这项研究是在英国盲人运动的支持下进行的,评估了封锁政策对英国视力障碍成年人的影响。方法:一项基于世界卫生组织全球体育活动问卷的在线调查由73名参与者(中位年龄35-44岁,59%为女性)完成,以了解英国政府实施封锁政策如何影响视障成年人的体育活动和久坐行为。配对样本t检验和Wilcoxon符号秩检验分别用于分析连续和Likert量表数据。结果:大多数参与者在封锁期间继续锻炼,但这种活动的性质随着在私人室内空间锻炼的显著变化而改变(+190%(始终),z=−3.871,p<0.001),以及单独锻炼的参与者(+118%(始终)、z=−2.595,p=0.009)。在所有情况下,活动量都减少了,在−11%和−52%之间,剧烈日常活动、适度日常活动、步行或骑自行车旅行以及剧烈娱乐活动的持续时间发生显著变化。久坐行为平均增加21%(t(59)=−2.050,p=0.045),女性的影响更大(+36%,t(35)=−2.525,p=0.016)。讨论:体育活动量的减少和久坐行为的增加是英国封锁对视力障碍者的影响。这些数据对这一特定人群的健康和福祉影响尤其令人关切。对从业者的影响:封锁措施的设计应考虑到残疾人的需求。大力鼓励以创新的方式让这些人群参与体育活动。

Introduction: Access to efficient and affordable transportation options has long been a challenge for many individuals with vision loss. In spring 2020, the COVID-19 pandemic caused a quick shift in the availability and safety of transportation. Methods: Using the constant comparison method, open-ended responses from 1,162 participants in the Flatten Inaccessibility study were coded. Responses were from participants who had concerns about transportation. Results: Ten themes and corresponding subthemes emerged from the data. Themes were interdependent in that the extent of concerns differed based on respondents’ support networks, transportation availability, and financial circumstances. Discussion: The COVID-19 pandemic brought to the forefront both systemic and COVID-19 transportation challenges about which those with visual impairments experienced or had concerns or both. Implications for Practitioners: It is imperative that professionals support those with visual impairments to develop alternative plans for when their typical transportation options are disrupted.
长期以来,对于许多视力丧失的人来说,获得高效和负担得起的交通选择一直是一个挑战。2020年春季,COVID-19大流行导致交通运输的可用性和安全性迅速转变。方法:采用恒值比较方法,对来自Flatten Inaccessibility研究的1162名参与者的开放式回答进行编码。回答来自对交通有担忧的参与者。结果:从数据中产生了10个主题和相应的子主题。主题是相互依存的,因为关注的程度根据受访者的支持网络、交通可用性和财务状况而有所不同。讨论:2019冠状病毒病大流行将系统性和2019冠状病毒病交通挑战摆在了人们的面前,这些挑战是视力障碍人士经历或担心的,或者两者兼而有之。对从业人员的启示:当他们的典型交通选择被打乱时,专业人员必须支持那些有视觉障碍的人制定替代计划。
