Netiquette: Ethic, Education, and Behavior on Internet—A Systematic Literature Review

In this article, an analysis of the existing literature is carried out. It focused on the netiquette (country, date, objectives, methodological design, main variables, sample details, and measurement methods) included in the Web of Science and Scopus databases. This systematic review of the literature has been developed entirely according to the Preferred Reporting Items for Systematic Reviews (PRISMA). The initial search yielded 53 results, of which 18 exceeded the inclusion criteria and were analyzed in detail. These results show that this is a poorly defined line of research, both in theory and in practice. There is a need to update the theoretical framework and an analysis of the empirical proposals, whose samples are supported by students or similar. Knowing, understanding, and analyzing netiquette is a necessity in a society in which information and communication technologies (ICT) have changed the way of socializing and communicating. A new reality in which there is cyber-bullying, digital scams, fake news, and haters on social networks.


Introduction
Billions of people have taken an active part in technological development over the past decade. Social networks have been the maximum exponent of a digital revolution that has meant a before and after in terms of how people communicate and collaborate [1]. A new reality that has been mutating from the original Facebook, YouTube, and Flickr [2] to become, for example, a relevant strategy in election campaigns [3][4][5]. The perfect framework for its expansion has been mobile devices, especially smartphones [6,7]. Both its technical conditions and its rapid incorporation into almost any area of life today [8] have made it the perfect nexus. In fact, nowadays it is not surprising that applications such as Instagram [9], or others more associated with instant messaging [10], are among the most frequented practices when accessing these mobile devices [11].
The popularity and growth of social networks can be understood by the paradigm shift that brought about their birth, as previously the World Wide Web was based on limited usability. Its appearance meant that users were already able to create, modify, share, and discuss existing content on the Internet [12]. Consequently, the attractiveness of using these digital media was no longer governed only by the content, but also by the new possibilities of participation they offered [13]. Although it has not been total, as the digital divide is still present [14][15][16][17], one of the technological consequences of the second decade of the 21st century has been the easy access to these new opportunities [18]. Despite cultural differences and resistance [19], it is clear that the option of being part of and participating in these digital communities [20] has been reduced to a couple of keystrokes.
This new digital map, which over the years has unlocked new horizons, has altered such basic habits as what to take with you when you leave home: wallet, keys, and new digital habits in students [74,75]. In the case of the educational field, the pandemic has highlighted the role of ICTs [76], a reality which means understanding the digital label as part of human development in the 21st century. An approach that has been focused above all on students who have grown up with the digital [77] but which, in reality, is already inherent to anyone who has access to a mobile device with an Internet connection.
The present study is based on this new paradigm. Access to digital media is already a routine, even an addiction, and it is urgent to understand its new social patterns. In the educational field, especially in training, this idea is becoming increasingly present. This is due, on the one hand, to the progressive integration of ICTs into the teaching-learning processes and, on the other hand, to the impact of these changes in terms of defining what DC is and how to develop it in schools. For this reason, this work focuses on explaining the scientific reality of the term "netiquette" through a review of the literature in the main databases. This is an approach to finding out and understanding the state of research into labels in a universe marked by haters, cyberbullying, and fake news.

Method
This systematic review is based on the analysis of existing literature in the Scopus and Web of Science (WoS) databases of the term netiquette. Its implementation has been developed in accordance with the Preferred Reporting Items for Systematic Reviews (PRISMA) [78] in order to answer the following questions. The structure of other publications in impact journals [79][80][81] has also been taken into consideration in order to follow models of analysis validated by experts. In turn, data from the studies analyzed are included, such as the country of origin, the date of publication, the main objectives, the methodological design, the variables considered, the details of the samples, and their scientific contributions to the area of research.
RQ1 What is the state of scientific production regarding "netiquette"? RQ2 Has an interest in "netiquette" increased since the emergence of social networks? RQ3 What is the scientific relationship between "netiquette" and the educational field?

Search Strategy
During the month of December 2019, a strategy was developed based on the search for articles that include the term "netiquette" in the title and that are part of two relevant scientific databases. Given the nature of this research, this restrictive criterion was chosen because otherwise the inclusion of articles that were not scientifically relevant to the research could be favored. In this sense, both terms were included in the Scopus and WOS search engines (WOS, BCI, BIOSIS, CCC, DIIDW, KJD, MEDLINE, RSCI, SCIELO), two scientific databases commonly used by experts and researchers and from which both JCR and SJR draw their information [82]. A single search criterion was established, the title of the article having to incorporate one of the two terms. This initial search yielded 53 manuscripts, although the final sample consisted of 18 references.

Inclosure Criteria
The channeling of the results to the final sample was carried out on the basis of the PRISMA protocol [78] for carrying out systematic reviews. The main objective was to analyze those articles that really focused on "netiquette," and so it was established as a search criterion that this term should appear in the title of the articles to be analyzed later. Afterward, those results that were not articles were eliminated, both in WOS (n = 13) and in the SCOPUS database (n = 9). Of the 31 resulting articles, having searched two databases, those that were duplicated and were part of both were eliminated (n = 10). Once they were deleted, the information available on the remaining 21 articles was analyzed to check their eligibility, and they were read in full in cases of doubt about their subject matter. Finally, those whose complete text could not be found on the Internet were eliminated (n = 3), leaving the final sample reduced to 18 articles ( Figure 1). Articles included in the title "netiquette" or "netiquettes," not repeated in the databases and with access to the full text.

Results
All the articles that have been considered for analysis were presented in English (n = 18). A consistent figure considering that more than half (n = 12) have been published from the UK (n = 4) or the US (n = 7). The time span between the oldest and most recent article is 23 years, covering 1995 and 2018. The focus of the articles can be grouped into two main blocks, empirical studies (n = 9) and theoretical approaches (n = 9), as shown in Tables A1 and A2 respectively. The methodological disparity is clearly noticeable in the quantitative articles, with cases of quantitative (n = 4), mixed (n = 2), and qualitative (n = 1) approaches. (Appendices A and B).

Country
More than half of the articles studied were of Anglo-Saxon origin, specifically from the United Kingdom [61,64,70,76] and the United States [59,60,[65][66][67][68][69]71]. Both cases stand out as they are the only countries that are repeated in terms of place of publication. The remaining (n = 6) come from European countries, such as Germany [78], Denmark [62] and Belgium [72]; from Asia, South Korea [54] and Jordan [74]; and from the American continent, Mexico [75]. Article [66] should be defined as having double authorship, from the United States and Canada. It should be noted that the United Kingdom [61,70] and the United States [59,60,[65][66][67][68][69] are the only two countries that contribute articles of a theoretical nature, while those with an empirical focus are more spread out around the world.

Aims
On the one hand, the objectives of the empirical articles can be differentiated into those more linked to netiquette in educational contexts [54,71,72,74,75,77] and those oriented to more general personal or work environments [62,64,76]. In the majority of articles [54,62,64,72,[74][75][76][77] the objective is based on knowing habits associated with the label on the net, in some cases, the objective is purely methodological [71]. As for the theoretical articles, the distinction is less clear. Up to 5 [59,[65][66][67][68] focus on exposing or analyzing guidelines related to the correct use of electronic mail and two [60,61] provide more general guidelines for the Internet in its complexity. Only three are developed for specific contexts: hospital workers [68,69] and librarians [70].

Main Variables
The variables found in the articles analyzed are very diverse. The quantitative variables explore online time and its possible relationship with cyber-bullying [54] or peer-topeer tagging [64], university students' knowledge of it [74], or its direct application through interaction with faculty [77]. In the case of those based on a mixed methodology [62,72], they are based on category analysis (attitude, motivations, unsubstantiated statements, etc.,) and are interspersed with other numerical quantitative variables (questions, number of visits to the forum, number of times they read what is published in the forum, etc.,). The qualitative article [75], with a socio-historical perspective, is based on categories such as "moral practice," "communities of practice," and "netiquette."

Sample Details
The samples in half of the articles analyzed [54,62,64,71,72,[74][75][76][77] are very varied. They range from small groups of 34 secondary school students [75] to 992 couples [64] or 2849 students and teachers [77]. The educational context of the samples is relevant, as more than half [54,71,72,74,75,77] of the articles are composed of students or graduates. There are also undefined figures when exposing themselves based on groups [76] and samples where the only requirement was to have a Facebook account [62] or to have a partner [64].

Measurement
The instruments used in the articles analyzed cover quantitative [54,64,74,77], mixed [62,72], and qualitative [75,76] perspectives. In this sense, the quantitative instruments have been based on the development of questionnaires designed ad-hoc [54,64,74,77], the mixed ones have been questionnaires and subsequent coding, and the qualitative ones have employed interviewing and discourse analysis individually or through focus groups. The theoretical articles have not used instruments in their development.

Discussion
The last two decades have shown the capacity for technological development and the human ability to incorporate it into daily routines [9][10][11]31,32,35]. In the case of the Internet, its birth and evolution have meant a before and after in humanity [12,13,33,34], and has altered the way people communicate and collaborate [1,18]. Having and using a smartphone [21], even becoming addicted [51], or spending time on social networks [2] are new patterns of behavior in a society where digital skills are becoming essential [26,27,29,36,38]. So much so that in the educational field the relevance of the so-called DC [39][40][41][42][43]50] is increasing. In short, it is clear that these years have seen the birth of a new question that goes beyond ethics: how to behave on the Internet [20,28,37,38,60,61].
In relation to the instruments indicated in the literature analyzed, the disparity in the methodologies and tools used stands out. The quantitative researchers base their analysis on ad-hoc questionnaires [54,64,74,77] whose scientific criteria are not clear, so it is complex to affirm their validity and that they are reliable. At the same time, the sample sizes are disparate, with figures that are either not very representative [62,75] or fairly representative [54,64,77]. On the other hand, methodologies supported by open questions, coded analysis of discussion groups, or field diaries have also been found. On no occasion are the objectives of two or more articles repeated or similar, each of the articles analyzed is supported by unique theoretical frameworks and instruments.
The results presented by the articles researched can be grouped into two aspects. Theoretically, the relevance of the correct use of electronic mail in the digital world is revealed through the presentation of guidelines and guides [59,[65][66][67][68]. On the other hand, digital trends are shown, such as cyberbullying [54], mourning, and commemoration practices on Facebook [62], and the impact on couple relationships [64]. In the educational framework, there are complementary ideas such as the lack of knowledge of netiquette on the part of university students [74] and the improvement in the quality of discussion in forums when guidelines of this type are provided previously [72].

Conclusions
Considering the results found in this work, it is consistent to conclude that netiquette is a field of study that is in its initial phase. The limited production in this line of research is very significant, especially in view of the existence of theoretical articles from more 7 of 15 than two decades ago. It is complex to consider that there is a real interest in research in this area. Defining an ethic for a context that changes almost daily is complex, however, it is necessary to understand it if we want to improve the society. The DC [39] includes netiquette as a training demand, both from students and teachers, and it is understood in reality that it includes digital economic sectors, the rise of cyberbullying [54], or the establishment of nomophobia [51].
Different considerations can be made with regard to the starting hypotheses. Scientific production relating to netiquette is still at an early stage, without a defined theoretical basis despite being a term that has existed since before the 21st century. The birth of social networks has indeed increased the interest in netiquette, at least in terms of new habits and specific ethical factors. The works published in the past decade take into account the existence of these new media, a vision that is coherent with how they have become internalized in the routine of billions of people. The selection of students in training, whether current or recent, is a scientific criterion that reinforces the link between education and netiquette. Digital preparation is a fundamental pillar in personal, social, and professional terms. It is therefore inevitable to associate both areas in the present without thinking about the future, something that is set out in the current conception of the DC.
In relation to the limitations of the present study, existing in the studies based on the systematic review, there is a risk of having lost information because of the strategy of selection of the descriptor. Introducing the term netiquette, and its plural, as the only search elements were established in view of its presence in educational and legislative frameworks. Some of the lines of research in this area that are proposed are the creation of new instruments to find out the level of preparation of students, teachers in training, or teachers.
In conclusion, this study presents a number of theoretical and practical implications. The implications in the educational field, after having carried out the analysis, imply the need to revise the digital preparation of all the agents that form part of this field. The theoretical and practical synthesis set out in this work may mean a new scientific stage of an essential issue for the 21st century. Specifically, to cite more specific examples, it can lead to the beginning of a realistic consideration of digital needs, demands, and capacities in everyday tools such as e-mail, social networks, and even others close to home. For this reason, this study not only offers a new line of work to researchers or experts from the scientific community but can also have repercussions for anyone in the world with access to digital devices, with a special interest in the educational context. A netiquette is developed and negotiated consciously or unconsciously in intimate relationships. [71] United States 2012
