The Impact of Facebookers ’ Posts on Other Users ’ Attitudes According to Their Age and Gender : Evidence from Al Ain University of Science and Technology

This study aims at exploring the reasons that drive many Facebookers to share negative posts on Facebook, with a special focus on their gender and age. It also aims at identifying the negative attitudes and feelings that negative Facebook posts might evoke in Facebookers. Thus, a mixed-methods approach was adopted employing both a five-point agreement Likert scale questionnaire and semi-structured interviews which were conducted with 40 participants. Based on the participants’ responses, the results show that many Facebookers write posts to satisfy different needs including receiving compliments and attention, sharing daily updates, showing off, and deliberately teasing others, all of which have been found to trigger feelings of jealousy, hatred, annoyance, demotivation, inferiority, and sadness. The study concludes with recommendations for further research.


Introduction
Following the emergence of new technologies, the ways in which people communicate have been subject to drastic changes, especially taking into account that communication is becoming more virtual.According to Boyd and Ellison (2008), one of these new media technologies that have started to capture the attention of societies internationally is Social Media (SM).The current situation is far from being alarming since SM has given individuals the opportunity to communicate freely using language to suit their preferences (Duthler 2006).Undeniably, as noted by Sotillo (2012), one of the most commonly used means through which one could communicate and express oneself without restrictions using computer-mediated communication (CMC) is Facebook.This is due to the fact that it survives as one of the most used SM websites.Facebook has begun to be a venue for its users to share whatever is related to their personal lives; relationship status, academic achievements, work, photos, check-ins, hobbies, etc.It can be indicated that Facebook has started to serve as a preface to its users.Posts shared by Facebook users (henceforth, Facebookers) pave the way for much interaction through different Facebook tools such as 'Like', 'comment and reply', and 'share'.Unsurprisingly, the habitual use of Facebook has become integral in the lives of its users through specific routines and rituals.It has also become an indispensable tool of social capital with many people (Debatin et al. 2009).In this respect, Sotillo (2012) explained that CMC used on Facebook has been investigated from various viewpoints in numerous disciplines, including sociolinguistics, sociology, behavioural psychology, communication studies, and discourse analysis.However, examining the effect of negative Facebook posts on the feelings and attitudes of other users is an under-investigated issue.Facebookers post, interact, and

Advantages of Facebook Use
Numerous studies in the relevant body of literature have supported the fact that the advantages of using Facebook use are abundant.For example, one study showed that using Facebook is beneficial for those with low self-esteem and low-life satisfaction, as it helps them improve three dimensions of social capital: (1) 'bridging', as Facebook use can lower the barriers to communicating with or responding to others by allowing those who may shy away from initiating communication to do so through Facebook's affordances; (2) 'bonding', as Facebook may help users maintain pre-existing close relationships and keep tabs on distant acquaintances; and (3) 'maintaining social capital', as Facebook helps college students maintain relationships with high school friends, for instance, and offset the feelings of 'friendsickness' caused by loss of old friends (Ellison et al. 2007).In addition, using Facebook would help people maintain relationships as they move from one offline community to another or Soc. Sci. 2018, 7, 128 3 of 14 when students graduate from college.Such connections could have strong payoffs in terms of jobs, internships, and other opportunities (Ellison et al. 2007).
Moreover, intensive Facebook use was shown to be positively associated with students' social capital, that is, their life satisfaction, social trust, civic engagement, and political participation (Valenzuela et al. 2009).Specifically, through certain Facebook applications, such as 'Facebook groups', users satisfy their informational and integrative needs (Valenzuela et al. 2009).Facebook allows users to create and join groups that are based around common interests and activities (Valenzuela et al. 2009).Hence, increased participation in online and offline groups helps to build trusting relationships and, in turn, increase social capital.(Kobayashi et al. 2006).
It was also shown that the increase in status updating activity by sharing daily experiences and letting friends take part in one's life leads to more connectedness among Facebookers (Deters and Mehl 2013).Furthermore, status updates draw attention to the user and might motivate friends to initiate social interaction, which can alleviate loneliness independently of direct social feedback (i.e., responses) by friends (Deters and Mehl 2013).The content of status updates might allow a conversation to develop from a small talk to more intimate levels (e.g., 'I read you got a new job.How is that going?'), which fosters social inclusion (Aron et al. 1997;Mehl et al. 2010).
In a recent study, Facebook use was found to be positively linked to users' psychological well-being through their online social relationship satisfaction or perceived social support (Hu et al. 2017).It was also suggested that online and offline social contexts complement and reinforce each other (Hu et al. 2017).Specifically, encouraging online social relationships on Facebook can broaden Facebookers' engagement in social activities and promote self-presentation, all of which can have an impact on offline social relationships (Hu et al. 2017).Further, reinforcing offline social relationships helps people get intimacy, interpersonal trust, strong social ties, and may help Facebookers sustain more meaningful and closer social relationships online (Hu et al. 2017).

Disadvantages of Facebook Use
Notwithstanding the numerous advantages of using Facebook, several studies have suggested that it can be equally harmful.
For instance, Facebook has the potential to provoke jealousy-related feelings and suspicion in romantic relationships (Elphinston and Noller 2011;Muise et al. 2009).Facebook intrusion, which is an excessive attachment to Facebook, interrupts people's daily tasks leading to jealousy and relationships dissatisfaction; the interpersonal nature of Facebook along with third-party threats to relationships partners encourage jealousy feelings and engagement in surveillance behaviours, which can lead to dissatisfying romantic relationships (Elphinston and Noller 2011).The fact that Facebook is a public domain enables people to access information about their partner that may be interpreted in several ways due to the misinterpretation of information out of context, which can increase people's concerns about their relationships quality (Muise et al. 2009).
Furthermore, Facebook use predicts negative shifts in cognitive and affective well-being over time; the more people used Facebook at one time, the worse they felt, and the more their life-satisfaction declined (Kross et al. 2013).This was in contrast to the 'direct' social interaction that did not predict such negative results (Kross et al. 2013).Additionally, frequent Facebook interaction has been found to be associated with greater stress directly and indirectly via a two-step pathway leading to both increased communication overload and reduced self-esteem (Chen and Lee 2013).
Facebook use has also been found to evoke feelings of envy, which is an unpleasant emotion characterized by feelings of inferiority, hostility, and resentment caused by an awareness of what others enjoy (Smith and Kim 2007).On Facebook, people share their positive experiences to develop an attractive online persona, which leads to 'envy', and that, in turn, mediates the effect of Facebook surveillance use on depression (Tandoc et al. 2015).In addition, feelings of envy can be exacerbated by passive following of others' information, which may lead to frustration, exhaustion, and decreased life satisfaction, as it triggers upward social comparison and invidious emotions (Krasnova et al. 2013).

The Effect of Gender and/or Age on Facebook Use
Through reviewing the related literature, it appears that several studies have focused on the effect of gender and/or age on Facebook use (e.g., Debatin et al. 2009;Mazman and Usluel 2011;Dey et al. 2012;Mcandrew and Jeong 2012 among others).For instance, through conducting an online survey on 119 college undergraduates at a large university in the Midwestern United States followed by interviews with eight participants, Debatin et al. (2009) examined the awareness of Facebookers regarding privacy issues and the risks and benefits of using Facebook.The results showed that the respondents of the survey were predominantly females, i.e., 68% and the largest age group was between 22-24 years old.This suggests that females as well as younger participants were more interested in providing answers related to Facebook use, especially those pertaining to privacy issues and uploading personal information.Interestingly, the results revealed that even though the participants did claim to be aware of privacy issues, they did upload substantial amounts of personal information, which proposes a tendency to share personal information on Facebook regardless of privacy invasion.Despite the fact that all interviewers agreed that Facebook fuelled rumours and gossip, they kept using it since they believed that that was a mere side-effect of Facebook usage.It seems that Debatin et al. (2009) examined the extent to which Facebookers understand the issue of privacy and sharing personal information, yet they did not investigate the effect of gender and/or age on the negative posts shared on Facebook or the negative feelings such posts may provoke in others, which is the main objective of the current study.
In another study, Mcandrew and Jeong (2012) investigated how different people use Facebook through including an international sample consisting of 1026 Facebookers, 284 of whom were males and 735 were females.The participants completed an online survey related to their Facebook activities.Similarly to Debatin et al. (2009), the results revealed that the most active Facebook users were females, younger people, and other individuals who were not committed to a relationship at the time of data collection.Mcandrew and Jeong (2012) indicated that in comparison to males, younger females spent more time on Facebook, had the tendency to use profile pictures to impress people, and had more Facebook friends.In contrast, women and older participants were more interested in online family activities.Concerning relationship status, the results also demonstrated that females had more interest in knowing people's relationship status compared to males.They also kept tabs on other females' activities as opposed to males.As far as age is concerned, it was shown that older people spent less time on Facebook, were less active, and had fewer Facebook friends in comparison with younger people.It can be observed through Mcandrew and Jeong's (Mcandrew and Jeong 2012) study that age and gender can have an impact on the way individuals use Facebook on an international level.The current study, however, aims to explore the ways in which negative Facebook posts can be reflected in the attitude of Facebookers toward each other.

Research Objectives
Drawing on the previous research, it can be inferred that Facebook can be a double-edged sword for its users; as it can be advantageous, it can be equally detrimental (Hu et al. 2017).Hu et al. (2017) coined the term 'Facebook Paradox' to refer to the inconsistent and sometimes the contradictory impact of Facebook use on social relationships and psychological well-being.
The idea behind Facebook, in the first place, was to bring the world closer together, to keep up-to-date with current news, and to create a place where everyone can express what matters to them (Facebook 2017).In other words, Facebook was founded to improve people's lives socially and psychologically.Unfortunately, many Facebookers have used Facebook in a way that contradicts its original purpose.They have started to use Facebook as a malicious tool that would help them satisfy many immoral motives.Inevitably, this may evoke negative feelings in many Facebookers.It would also have a negative impact on their attitudes towards each other that may extend to face-to-face interactions offline; especially given the fact that many Facebookers know each other in person not only via Facebook.To the best of our knowledge, previous research on Facebook use has not addressed the effect of the gender and age of Facebookers on the type of posts they write and share on Facebook; nor has it aimed at identifying the negative feelings and attitudes such posts may provoke in others.Thus, we are left with a gap this study seeks to close to obtain a better understanding of the behaviour of Facebookers and the effect of their gender and age on the type of posts they write and share, especially in the Arab world, namely in the United Arab Emirates (UAE).Therefore, this study aims at providing potential answers to the following research questions: (1) To what extent does the gender and age of Facebookers in Al Ain, UAE, have an impact on the type of posts they write and share on Facebook?(2) What kind of negative attitudes and feelings that negative Facebook posts (i.e., those that provoke negative feelings such as envy) may evoke in Facebookers of different genders and ages in Al Ain, UAE?
The next section describes the methodology adopted in the current study.

Participants
The population of the current study included the academic staff, administrative staff and students at Al Ain University of Science and Technology, Al Ain, the United Arab Emirates (UAE).However, the sample of the study included 300 participants-a mix of students, academic staff, and administrative staff, at Al Ain University of Science and Technology.They were chosen randomly through conducting stratified random sampling using lists of all staff and students at Al Ain University.Males and females are listed separately by the university, which helped in obtaining an equal division.The stratified random sampling was conducted through dividing the population into homogenous strata or groups and then selecting a random sample out of each stratum (Frankfort-Nachmias and Nachmias 2007).Our random sample was chosen based on gender, age and the duration of Facebook use.This sample was further filtered to include only those who have used Facebook for more than two years.Those who did not have enough experience with Facebook, that is, they used Facebook for less than two years, were excluded from the study after data collection in order to ensure accuracy of data.The random sample chosen in this study was taken in a number proportional to the stratum size when compared to the population (Frankfort-Nachmias and Nachmias 2007).The 240 remaining participants were divided into two groups according to their gender and age, as Table 1 below shows.

Data Collection
This study adopts a mixed-methods approach, whereby researchers collect and analyse target data via employing and integrating the results arrived at from both quantitative and qualitative methods (Creswell 2008).Denscombe (2010) suggested that the purpose of adopting a mixed methods approach centres on highlighting the strength of each approach and overcoming any of their perceived weaknesses in order to offer a more comprehensive answer to the research questions.The nature of the research questions in the current study makes the use of a mixed-methods approach essential, since the Soc.Sci.2018, 7, 128 6 of 14 researchers are interested in investigating the reasons that drive Facebookers to share negative posts on Facebook and whether their age and gender can have an impact on their behaviour.Thus, adopting this method may help in obtaining a good understanding of the participants' views and experiences and in providing them with the opportunity to elaborate on the answers they provided on the questionnaire.This suggests that the researcher can corroborate the results obtained via quantitative data elicitation tools through examining their answers attained via another tool, a process referred to as triangulation (Creswell 2008;Torrance 2012).In the current study, a questionnaire was used as the quantitative data elicitation tool, while a semi-structured interview was employed as the qualitative one.These two tools are discussed in the following sections.

The Questionnaire
The questionnaire of this study consisted of two sections.The first section aimed at obtaining information about the participants' gender, age, and duration of experience with Facebook.The second section aimed at collecting quantitative data.The second section consisted of 20 statements to which the participants responded using a five-point agreement Likert scale, a ubiquitous tool for the measurement of attitudes (Likert 1932) in the field of social sciences that is supported and used by multiple researchers (Ellison et al. 2007;Kalpidou et al. 2011;Altakhaineh and Zibin 2014;Altakhaineh and Rahrouh 2015;Hu et al. 2017;Altakhaineh and Rahrouh 2017).To prevent social desirability bias 1 and to ensure accurate and truthful responses, the statements were tactfully worded.The tool was validated through checking the items with two professors of linguistics and any items that were deemed confusing or vague were omitted from the final version given to the participants.Additionally, the participants were not informed about the purpose of the study, they were not monitored while completing the questionnaire, and they were assured that their information would be kept confidential.

The Semi-Structured Interview
Due to the fact that this study adopts a mixed methods approach, in addition to distributing the questionnaire for quantitative data analysis, semi-structured interviews, which are the most common type of interviews used in qualitative research (Holloway and Wheeler 2010), were conducted with 40 randomly chosen participants from those who already completed the questionnaire to discuss their responses.Semi-structured interviews were shown to provide depth in the analysis of the collected data; they help the interviewer to further expand the interviewees' responses as they allow for much negotiation and discussion (Hitchcock and Hughes 1989).According to Bernard (1988), the advantage of the semi-structured interview is that the interviewer controls the process of obtaining information from the interviewee, but is free to follow new leads as they arise.Conducting the semi-structured interviews with the participants gave us a more in-depth analysis of their answers and helped us to arrive at a reasonable conclusion regarding the reasons Facebookers create and share different posts and the negative attitudes and feelings these posts evoke in them.Before conducting the interviews, written formal consents were obtained from the participants as to have their interviews tape-recorded.The participants were assured that whatever information they provided in the interviews would be kept confidential, and that the recordings of the interviews would be permanently deleted.Tape-recording the interviews helped us limit the errors that could happen by simultaneously taking notes and observing the participants (Bassey 2006).Finally, the recorded data was transcribed to qualitatively analyse the participants' responses.

Statistical Analysis
In order to examine whether the differences between the two groups of participants, namely, males vs. females and younger vs. older Facebookers were statistically significant, a t-test was administered.This test is a statistical analysis tool of two populations means done via the use of statistical calculation.A t-test measures the t-statistics, degrees of freedom and the t-distribution in order to determine the probability of difference between the two populations.This test was used by other researchers to explore the statistically significant differences between the means of two groups (see Altakhaineh and Zibin 2014).

Results
For quantitative data analysis, the number of positive responses (responses that agreed with the questionnaire statements) in each of the gender and age groups was summed up.Table 2 below shows the extent to which the participants agreed with the statements.An examination of Table 2 shows that the percentage of positive responses provided by females (68%) is higher than that of males (47%).The same observation was noted in the responses of younger Facebookers (70%) and older ones (46%).This suggests that female Facebookers exhibit more negative feelings and attitudes towards Facebook posts in comparison with male Facebookers.Table 2 also demonstrates that younger Facebookers are more likely to show negative feelings and attitudes towards Facebook posts compared to their older counterparts (see Section 4.2 for more detail).In order to determine whether the differences between the responses supplied by these groups were statistically significant, two t-tests were calculated; one that examined the means of female and male Facebookers, and another one that examined the means of younger and older Facebookers.Table 3 presents the results of the two t-tests.A careful look at Table 3 demonstrates that the differences between the responses provided by female and male Facebookers were statistically significant (p value < 0.05).The same observation can be noted for the second group, i.e., younger and older Facebookers.
By analysing the data collected and interviewing 40 participants to discuss their responses, reasons for sharing posts on Facebook and negative feelings evoked by Facebook posts were determined and are summarised in Table 4.To provide a clearer picture of the negative feelings evoked by such posts as demonstrated by gender and age groups, Figures 1 and 2 present these percentages.
To provide a clearer picture of the negative feelings evoked by such posts as demonstrated by gender and age groups, Figures 1 and 2 present these percentages.Figures 1 and 2 show that sharing negative posts on Facebook is more likely to evoke negative feelings in female and younger Facebookers in comparison to male and older Facebookers.Specifically, these figures show that the percentage of negative feelings evoked by Facebook posts in female and younger Facebookers is higher compared to that of male and older Facebookers.The next sub-section further discusses the results presented in Tables 2 and 4 in order to provide potential answers to the research questions (i.e., 1.To what extent does the gender and age of Facebookers in Al Ain, UAE have an impact on the type of posts they write and share on Facebook?2.

What kind of negative attitudes and feelings that negative Facebook posts may evoke in Facebookers of different genders and ages in Al Ain, UAE?).

Discussion
To discuss the first part of the first research questions (i.e., impact of gender on the type of posts Facebookers write and share on Facebook), a careful study of the gender section of Table 4, taking into account the interviews conducted with the 40 participants, reveals many findings which are presented in the remainder of this section.First, the total mean of the females' positive responses was higher than that of the males, as shown in Table 2.
Second, as far as receiving compliments and feedback was concerned, females' positive responses outnumbered those of males; some females claimed that receiving compliments would make them feel more self-confident and more appreciated.Other female participants posited that they would feel jealous if their Facebook friends received more compliments than them.
Third, it seems like most male participants were not into sharing posts about their personal lives publically; 75% of male participants agreed that it was pointless sharing posts about the graduation certificate, the places they visit, or food they eat.During one of the semi-structured interviews, a male participant said: 'Constantly sharing posts about the incidents that happens in my life is trivial'.
Fourth, since females usually seek prestige, even online, they agreed that they would post 'check-ins', photos, and achievements on Facebook. Trudgill (1972, pp. 182-83) suggested that women tend to follow community prestige norms in contrast to the linguistic behaviour of men.Females, possibly, like attracting attention to their posts and getting likes and comments.In contrast, male participants, though not all, thought that this was a matter of showing off, and they would deliberately ignore such posts.This is similar to the results obtained by Mcandrew and Jeong (2012), who suggested that unlike males, younger females spent more time on Facebook, had the tendency to use profile pictures to impress people, and had more Facebook friends.Although some males might share different posts, photos, or 'check-ins', their intentions behind doing so, in the first place, would not be to brag about their looks, whereabouts, or achievements; they would do so just to keep a record of happy moments, as one of the male participant explained.In particular, semi-structured interviews with both male and female participants revealed that females are more likely inclined to show off on Facebook in comparison to males.These tendencies may arise from females' desire to stand out and show others how 'cool' their life is.Taking into account the arguments presented by Boyd and Ellison (2008) and Bazarova et al. (2012), such behaviour could reflect that females may care more about their self-representation and how others perceive them on SM websites, such as Facebook.Conversely, males do not seem to share the same behaviour patterns as that exhibited by females.
Fifth, both male and female participants agreed, to a great extent, that they would share photos in Facebook to deliberately annoy some Facebookers they knew in person (statements 6 and 7).Some participants claimed that this was a 'powerful way' to make some Facebook friends jealous or sad over something they desired but lacked.One male participant recalled how his friend intended to tease him by uploading photos of his newly obtained driving license and car.
Sixth, females' positive responses to statements 8, 15, 16, 17, and 18 greatly outnumbered those of males.As shown in Figure 1, Facebook posts are more likely to evoke negative feelings in females compared to males.Specifically, many female participants agreed that they would compare themselves to others who showed how successful and happy they were, so they would feel envious, inferior, unmotivated, and lagging behind.In this regard, Chou and Edge (2012) suggested that envy feelings can be triggered when users engage in social-comparison browsing news feed, which can cause inferiority attitudes leading to depression and poor mental health (Smith and Kim 2007).Envy, in this study, can be described as 'malicious envy' which is characterised by having no good intensions for others or by having no motivation for improving one's self (Smith and Kim 2007;Van de Ven et al. 2009).The semi-structured interviews revealed that such negative feelings evoked by Facebook posts can negatively affect social relationships between Facebookers both online and offline.One female participant mentioned that feeling resentment towards an individual as a result of a post he/she shared online can transfer to their offline relationship, causing it to be severed in some cases.However, an interesting point that was raised by a female participant pertaining to this issue during the semi-structured interview was that keeping pretence online and showing that she is not jealous or envious of a specific person is normal because nobody likes to look vulnerable or lose face in front of others.This type of behaviour may show that individuals care about how they appear on virtual space as much as they care about their appearance offline.
Seventh, regarding the negative feeling of 'annoyance' stated in statement 11, males thought that Facebookers ought not to post photos of food on Facebook.They claimed that doing so was immoral.Interestingly, a male reported during the semi-structured interview: 'why would I post photos of food?There is nothing to celebrate about having a sandwich for breakfast!Why don't we just sympathise with those who cannot find something to eat?' On the other hand, females liked the idea of posting photos of food along with their recipes on Facebook, as they would learn how to prepare different dishes.Some females would post photos of cooked meals just to brag about the fact that they are good cooks.With respect to statements 13 and 19, which were about political and religious posts respectively, females' positive responses were higher than those of males.Many females, though not all, would get annoyed if they encounter a political or religious post that opposed their views because they thought that whatever they believed in was right.This can be ascribed to the fact that they were brought up to these religious or political views.'I may not show it, yet it annoys me to read posts of people who do not hold the same religious or political views as me', said a female participant during her semi-structured interview.In contrast, many males believed that Facebookers had to respect others no matter their religious or political views, and this should not interfere with people's attitudes towards each other.
Regarding the second part of the first research question (i.e., the impact of age on the type of posts Facebookers write and share on Facebook), the age section of Table 2 shows that younger participants' mean of total positive responses (70%) was higher than that of older participants (46%).
The positive responses of younger participants to the 20 statements outnumbered older participants' ones and even passed the average point (50%), with the exception of their responses to statements 3, 11, and 20.This is because older participants strongly agreed that it was pointless posting photos of 'the graduation certificate' (77%), food (74%), and personal photos (78%) on Facebook.This was 'lack of maturity', as an old participant put it during the semi-structured interview.In addition, older participants, though not all, would not use Facebook to share updates and information about their personal lives.In particular, they claimed that this would put them under threats of stalkers or haters who would plot against them using their publicised personal information.This argument is similar to that of Debatin et al. (2009), who suggested that although the younger participants did claim to understand privacy issues, they did upload substantial amounts of personal information, which proposes a tendency to share personal information on Facebook regardless of privacy invasion.Further, older participants did not know how to use Facebook as younger participants did; many older participants lacked knowledge of Facebook tools such as 'check-in' or 'tag', so they would not think of Facebook as a tool to help them satisfy any malicious motives.An old participant stated during the interview: 'I use Facebook as a way to communicate with friends whom I do not see anymore'.Since older participants do not spend much time on Facebook, they would not, possibly, be as much affected with the negative Facebook posts as the younger ones.This justifies the low average of older participants' agreement with most of the statements.In contrast, many younger participants, especially young adults, who represent a core Facebook user demographic (Kross et al. 2013), would be affected by the different posts shared.This is because they agreed that they would feel jealous of achievements, photos, and relationship statuses shared by others.Furthermore, they agreed that they would feel irritated or sad when they encounter sad posts.One young participant reported: 'It really annoys me when I read someone's post about how sad and angry they feel; I would unfollow that friend!' Generally, since younger participants spend much time on Facebook, they know how to utilise different Facebook tools of sharing photos and videos, tagging, and 'check-in' to satisfy their malicious intensions of teasing and humiliating others.
Finally, referring back to the research questions, in sum, the results showed that the gender and age of Facebookers do have an impact on the posts they write and share on Facebook (cf. Debatin et al. 2009;Mcandrew and Jeong 2012).They also demonstrated that negative Facebook posts can evoke various negative feelings mainly in female Facebookers in comparison to male ones and in younger Facebookers compared to older ones.

Conclusions
This study has examined the effect of gender and age on the posts written and shared on Facebook and whether these posts evoke negative feelings in both groups.By adopting a mixed-methods approach, distributing questionnaires and conducting semi-structured interviews with Facebook users in Al Ain University of Science and Technology, the results showed that Facebook has been used to satisfy different needs of getting compliments and attention, sharing daily activities and updates, showing off, and irritating others, all of which have been found to evoke feelings of jealousy, hate, annoyance, demotivation, inferiority, and sadness in others.In other words, Facebook has possibly become an uncomfortable place where Facebookers hold negative attitudes toward each other.Mitigating the overall impact of negative Facebook posts is not easy, yet it is crucially suggested that Facebookers try to control their ill-intentioned acts online bearing in mind that psychological and social maladies can be as detrimental as any other physical maladies.Finally, further research studies on the extending impact of negative Facebook use on people's relationships need to be conducted.Besides, the increasing rate of suicide due to 'Facebook bullies' calls for serious investigation (see Arkell 2013).
