There are abundant anecdotes and warnings of inappropriate behaviors on social networking sites, particularly about Facebook. The purpose of the present study was to examine whether individuals obsessively monitor or harass their ex-partners on Facebook (related to general "Facebook stalking") and, if so, whether those individuals would also engage in cyber obsessional pursuit (COP) and obsessive relational pursuit (ORI), which are categories of cyberstalking and stalking. A total of 411 valid participants answered questions about the ways they communicated with their ex-romantic partners using Facebook, resulting in three factors: Covert Provocation, Public Harassment, and Venting. Each category of Facebook harassment was related to perpetration of COP and ORI. Additionally, participants who engaged in COP were almost six times more likely to also perpetrate ORI. If participants admitted to engaging in some types of stalking behaviors, they did so online, offline, and on Facebook. Implications for social networking site usage and stalking laws are discussed. There is a kernel of truth to the popular term "Facebook stalking." ||||| To cite this article:

 Previous research has found that continuing offline contact with an ex-romantic partner following a breakup may disrupt emotional recovery. The present study examined whether continuing online contact with an ex-partner through remaining Facebook friends and/or engaging in surveillance of the ex-partner's Facebook page inhibited postbreakup adjustment and growth above and beyond offline contact. Analysis of the data provided by 464 participants revealed that Facebook surveillance was associated with greater current distress over the breakup, more negative feelings, sexual desire, and longing for the ex-partner, and lower personal growth. Participants who remained Facebook friends with the ex-partner, relative to those who did not remain Facebook friends, reported less negative feelings, sexual desire, and longing for the former partner, but lower personal growth. All of these results emerged after controlling for offline contact, personality traits, and characteristics of the former relationship and breakup that tend to predict postbreakup adjustment. Overall, these findings suggest that exposure to an ex-partner through Facebook may obstruct the process of healing and moving on from a past relationship. 
 
 The present study examined whether online exposure to a former romantic partner contributed to breakup recovery and growth above and beyond offline exposure. Previous research has established that offline contact is associated with poorer postbreakup functioning; for example, almost half of university students who have experienced a breakup continue to see or talk with their former partner, 8 , 9 even though this contact is associated with greater sadness and love for the ex-partner. 10 From the perspective of social network analysis, 11 maintaining offline contact with an ex-partner may preserve a strong-tie contact—frequent, reciprocal, and close contact—that ultimately inhibits breakup recovery. On the other hand, remaining Facebook friends with an ex-partner and/or engaging in surveillance of his or her Facebook page may maintain a weak-tie contact—infrequent, nonreciprocal, and casual contact. Weak ties can provide access to information that may not be obtained through strong ties, 12 such as information obtained through Facebook about the ex-partner's current activities. Such weak-tie contact may therefore sustain exposure to the ex-partner even in the absence of offline contact, potentially prolonging distress and longing for the former partner. The purpose of the present study was to examine whether weak-tie contact through Facebook sufficiently contributed to postbreakup functioning beyond strong-tie contact. This study also examined whether online contact was negatively related to breakup recovery and growth over and above certain personality traits (self-esteem, attachment style) and characteristics of the former relationship and breakup (e.g., feelings for the partner before the breakup, time since the breakup occurred) that consistently predict postbreakup adjustment. 8 , 13 The following hypotheses were tested: 
 
 Other research suggests, however, that Facebook may facilitate behaviors associated with obsessive relational intrusion—the unwanted pursuit of an intimate relationship, particularly with an ex-romantic partner. 7 Although Facebook surveillance falls on the mild end of the spectrum of relational intrusion, 3 research has found that monitoring an ex-partner's Facebook photos and other forms of covert provocation (such as writing a status update to make an ex-partner jealous) is associated with an increased likelihood of engaging in offline obsessive relational intrusion (e.g., showing up at the ex-partner's classroom or workplace). 4 Even for individuals who do not engage in relational intrusion, monitoring an ex-partner's online behavior may increase distress over the breakup and prolong pining for the former partner. For example, looking at an ex-partner's Facebook photos may renew desire for the former partner, or it may be upsetting to discover through Facebook that an ex-partner is involved in a new relationship. 
 
 Many of the features that make Facebook attractive to its users—easy, free, and anonymous access to information about others—can also facilitate online monitoring behavior. Excessively checking others' Facebook profiles has been variously referred to as interpersonal electronic surveillance, 5 Facebook surveillance, 2 or, more colloquially, as “Facebook stalking.” In particular, people may use Facebook to keep tabs on an ex-partner's current activities by checking his or her status updates, wall posts, comments, and photos; even if one is no longer Facebook friends with an ex-partner, publicly available information—such as a profile photo and list of friends—can still provide a rough approximation of the ex-partner's ongoing activities. Recent estimates have suggested that one-half to two-thirds of people have made contact with an ex-partner through Facebook, 3 , 4 and that over half admit to having looked through an ex-partner's photos to find pictures of an ex-partner with a new romantic partner. 4 Not only is Facebook surveillance of ex-partners relatively common, then, but people who engage in it tend to perceive it as harmless. 6 
 
 W ith more than 900 million active users, Facebook is currently the world's most popular social networking website. The two most cited reasons for using Facebook are to keep in touch with others and to surreptitiously monitor their activities. 1 Not only do people use Facebook to monitor the activities of current romantic partners, 2 but as many as one-third use Facebook to keep tabs on former romantic partners. 3 While Facebook surveillance of ex-partners has been linked to negative outcomes such as online and offline relational intrusion, 4 the potential for Facebook contact and surveillance to disrupt emotional recovery and growth following a breakup has received little research attention. The current study sought to fill this research gap by examining whether remaining Facebook friends with a former partner and checking his or her Facebook profile is associated with continuing breakup-related distress, negative feelings, desire for the ex-partner, and inhibited personal growth. 
 
 Current distress over the breakup was assessed with six items (e.g., “How much distress do you currently feel concerning the breakup?” and “How heartbroken are you when you think about the breakup?”). Participants indicated the extent of their negative feelings toward the ex-partner by rating how much anger, disappointment, confusion, hate, betrayal, hurt, frustration, and sadness they currently felt (selected in part from other work 10 , 17 ). Sexual desire for the ex-partner included items measuring lust, sexual arousal, and desire. All of the items measuring current distress, negative feelings, and sexual desire were rated on a 5-point Likert scale anchored with Not at all (1), A moderate amount (3), and A great deal (5). Longing for the ex-partner was assessed with four items 18 (e.g., “I am still in love with my ex-partner”) combined with three additional items 13 (e.g., “Everything seems to remind me of my ex-partner”). These items were rated on a 5-point Likert scale ranging from Strongly Disagree (1) to Strongly Agree (5). Finally, personal growth was measured by modifying the instructions of the 21-item Post-traumatic Growth Inventory 19 , 20 to ask participants how much life change they had experienced in different areas as a result of their breakup (e.g., “I developed new interests”). These items were rated with a 5-point Likert scale anchored with Not at all (1) and A great deal (5). 
 
 Participants were asked if they currently had offline contact with the ex-partner and were Facebook friends with the ex-partner. These two variables were effect coded (1=Yes, −1=No). Facebook surveillance was assessed with two items that were equally applicable to people who were currently Facebook friends with the ex-partner and those who were not: “How often do you look at your ex-partner's Facebook page?” and “How often do you look at your ex-partner's list of Facebook friends?” These items were rated on a 9-point scale ranging from Never (1) to Several times a day (9). Participants were also asked how many Facebook friends they had and how much time in minutes they spent on Facebook on a typical day. 
 
 Participants were asked to recall a distressing romantic breakup with someone whom they knew had a Facebook account. They indicated the status of the relationship before the breakup (nonexclusive dating, exclusive dating, cohabitating, engaged, or married), the length of the relationship, and how much time had passed since the breakup occurred. To assess feelings for the ex-partner right before the breakup, participants completed the six-item short-form of the Perceived Relationship Quality Components Inventory, 16 which assesses satisfaction, intimacy, trust, commitment, passion, and love. Two additional items were included that measured the degree of emotional involvement and sexual desire felt for the partner right before the breakup. Participants then indicated which partner initiated the breakup (“I did,” “My partner did,” or “We both did”). In the following analyses, initiator of the breakup was included as an effect-coded variable (1=partner initiated, −1=I initiated/we both initiated). Next, they wrote a description of the circumstances surrounding the end of the relationship, and completed the 16-item Breakup Distress Scale. 8 The instructions of this scale were modified to ask participants to recall the emotional distress they experienced immediately after the breakup occurred. Responses to this scale and to the measure of feelings for the partner before the breakup were rated on a 5-point Likert scale anchored with Not at all (1), A moderate amount (3), and A great deal (5). 
 
 It was stated at the beginning of the survey that participants must have a Facebook account and have experienced at least one relationship breakup with someone who also has a Facebook account to be included in the study. Several questions at the end of the survey addressed demographic variables and current relationship status. Cronbach's alpha coefficients for the following scales are reported in Table 1 . 
 
 Four hundred and sixty-four participants (84 percent female; M age =21.36, SD =5.49) were recruited by posting links to an online survey on several psychology survey-hosting websites (Social Psychology Network Online Social Psychology Studies, Psychological Research on the Net, and the intranet at the author's university). Eighty-seven percent were American, 7 percent were European, 2 percent were Canadian, 2 percent were Latin American, and the remainder were an international mix. Sixty percent of participants were currently working toward an undergraduate degree, 8 percent had completed an undergraduate or higher degree, and the remaining 33 percent had completed high school or A-levels. Forty-eight percent of participants were currently single; of those involved in a romantic relationship, 71 percent were exclusively dating their current partner, 8 percent were cohabitating, 8 percent were married, 7 percent were engaged, and 7 percent were nonexclusively dating. Current relationship status was included in the following analyses as an effect-coded variable (1=currently involved, −1=single). 
 
 As seen in Table 3 , many of the personality traits and characteristics of the past relationship and breakup entered at Step 1 significantly contributed to variance in the dependent variables. Additionally, offline contact was positively associated with current distress, desire, and longing for the ex-partner. More pivotal to the present study, the two Facebook variables entered at Step 2 significantly contributed to variance in the dependent variables over and above the predictors entered at Step 1. Contrary to Hypothesis 1, remaining Facebook friends with the ex-partner was negatively associated with negative feelings, desire, and longing for the ex-partner. In support of Hypothesis 1, however, remaining Facebook friends was associated with lower personal growth. Consistent with Hypothesis 2, Facebook surveillance was positively related to current distress, negative feelings, desire, and longing for the ex-partner, and negatively related to personal growth. 
 
 Table 3 reports the results of a series of hierarchical regression analyses that tested the predictors of current distress, negative feelings, sexual desire, longing for the ex-partner, and personal growth. For each analysis, the demographic and personality variables (age, sex, anxiety, avoidance, self-esteem), characteristics of the former relationship and breakup (length of the past relationship, feelings before the breakup, initiator status, breakup distress, length of time since the breakup, and current involvement), indices of Facebook usage (number of Facebook friends, average time per day in minutes spent on Facebook), and offline contact with the ex-partner were entered in Step 1. Average time per day spent on Facebook did not significantly contribute to any of the models, and was therefore removed. The key Facebook variables—whether participants were currently Facebook friends with the ex-partner and Facebook surveillance—were added in Step 2. 
 
 Means and standard deviations are reported in Table 1 , and Pearson's correlations in Table 2 . Additional analyses revealed that 82 percent of participants had been exclusively dating their former partner before the breakup, 38 percent indicated that their partner had initiated the breakup, and 44 percent indicated that they continued to have some offline contact with the ex-partner. Of the latter participants, 73 percent described themselves as close or casual friends with the ex-partner, suggesting a strong-tie contact. Fifty-seven percent of all participants reported that they were still Facebook friends with the ex-partner; of these participants, over 90 percent indicated that the ex-partner's Facebook wall, photo albums, profile photo, status updates, and list of friends were visible to them. Forty-six percent of participants who were still Facebook friends with the ex-partner indicated that they exchanged Facebook messages and comments with this former partner (81 percent of whom also maintained offline contact); of the 54 percent who remained Facebook friends with the ex-partner, but did not exchange any Facebook-mediated communication, 53 percent did not maintain offline contact, suggesting a weak-tie contact. Of the people who were not Facebook friends with the ex-partner, 25 percent reported that they had defriended the ex-partner, 12 percent reported that the ex-partner had defriended them, and 6 percent reported that they had never been Facebook friends with the ex-partner at any point in time. Less than 50 percent of these participants had access to their ex-partner's Facebook wall, photo albums, and status updates, but 86 percent could see their ex-partner's profile photo, and 72 percent could see their ex-partner's list of friends. That the measure of Facebook surveillance was based on the frequency of checking the ex-partner's Facebook page (which includes the profile photo) and friends list is therefore consistent with the visibility of these elements even for those participants who were not currently Facebook friends with the ex-partner.

 Taken together, these findings suggest that continued online exposure to an ex-romantic partner may inhibit postbreakup recovery and growth, even after accounting for the contribution of offline exposure and well-established personality and relational predictors. Notably, frequent monitoring of an ex-partner's Facebook page and list of friends, even when one was not a Facebook friend of the ex-partner, was associated with greater current distress over the breakup, negative feelings, sexual desire, longing for the ex-partner, and lower personal growth. These findings mirrored the correlates of offline contact, which was associated with greater current distress, sexual desire, and longing for the ex-partner, consistent with previous research.10 Facebook surveillance, therefore, accounted for aspects of postbreakup adjustment—negative feelings toward the ex-partner and lower personal growth—that offline contact did not. Importantly, these findings suggest that weak-tie contact with an ex-partner through Facebook contributed to poorer postbreakup functioning over and above strong-tie contact. Consistent with the view that weak-tie contact can supply information beyond strong-tie contact,12 Facebook may furnish information about an ex-partner that only intensifies heartbreak, such as news that the former partner is involved in a new relationship. 
 
 Contrary to expectations, people who remained Facebook friends with an ex-partner were lower in negative feelings, sexual desire, and longing for the former partner than people who were not Facebook friends. Although it seems likely that people who remained Facebook friends may have had weaker feelings for their partner before the breakup or experienced a more amicable split than people who had defriended the ex-partner, remaining Facebook friends was not significantly correlated with previous feelings for the ex-partner or breakup distress. An alternative possibility is that unbidden exposure to the potentially banal status updates, comments, and photos of an ex-partner through remaining Facebook friends may have decreased any residual attraction to the ex-partner. Former partners with whom we are no longer in contact, by contrast, may remain shrouded in an alluring mystique, suggesting that remaining Facebook friends with an ex-partner may actually help rather than harm one's postbreakup recovery. 
 
 Even so, people who remained Facebook friends were lower in personal growth than were those who had defriended the ex-partner, suggesting that even weak-tie contact with an ex-partner through remaining Facebook friends might disrupt the process of moving on. Although one might expect that the lower negativity, sexual desire, and longing for the ex-partner reported by participants who remained Facebook friends would be accompanied by greater, not lesser, personal growth, the former variables were not significantly correlated with personal growth. This lack of association is consistent with research that has found weak or nonsignificant relationships between indices of adjustment and personal growth following a traumatic event,21,22 suggesting that recovery and growth may be relatively independent processes. Indeed, healing from a relationship loss entails a process of recovering from negative emotions and detaching from the former partner, but also of developing a meaning-making narrative that enables personal growth.23 Thus, while remaining Facebook friends may benefit the breakup recovery process by mitigating negative emotions, desire, and longing for the ex-partner, it may simultaneously impede the construction of a personal growth-enhancing narrative. 
 
 The most notable limitation of this study is that the correlational design did not allow conclusions to be drawn about casual direction. Although these results suggested that offline contact and Facebook surveillance lead to poorer postbreakup adjustment and lower personal growth, it is just as plausible that people who were hung up on an ex-partner were more likely to seek them out in person and engage in greater Facebook surveillance, which in turn sustained the pining for the former partner. Likewise, people who stagnated after a breakup rather than experienced personal growth may have been more likely to retain the ex-partner as a Facebook friend. An experiment that compares participants who are encouraged not to check their ex-partner's Facebook page for a period of time with other participants who may check freely could shed light on whether Facebook surveillance is causally related to poorer postbreakup adjustment and growth. Furthermore, while it was beyond the scope of the current article to examine the motives behind remaining Facebook friends with an ex-partner and engaging in Facebook surveillance, these motives could be profitably explored in future research. For example, people who feel betrayed by an ex-partner tend to experience heightened breakup distress,8 and the current findings linked breakup distress with a greater likelihood of engaging in Facebook surveillance (see Table 2). Perhaps, then, people are more likely to engage in Facebook surveillance if a former partner has been unfaithful. 
 
 In spite of the need for further research, the take-home message from the present study is that keeping tabs on an ex-partner through Facebook is associated with poorer emotional recovery and personal growth following a breakup. Therefore, avoiding exposure to an ex-partner, both offline and online, may be the best remedy for healing a broken heart. ||||| It was in a weak moment of newfound singlehood that I thought, “Hmm, I wonder what he’s up to now.” Having severed our Facebook friendship, along with our romance, a few years ago, I clicked over to Flickr, the one place I knew could give me a glimpse into his life. And there it was: a self-portrait of him wearing a wedding ring. 
 
 Ignoring the gender dictates of marital tradition, I irrationally rationalized that it was merely an engagement ring. “No, he’s not married,” I thought. “Is he married? No way he’s married.” 
 
 Internet-stalker style, I found further proof on Twitter: Someone had live-tweeted a photo from the wedding. There he was in his tux at the end of the aisle during the sunny, outdoor ceremony. There were shots too of the bride and the happy couple’s Lego-people cake-topper. The term “TMI” is sorely overused, but this was the definition of it. It’s one thing to realize that the man you once wanted to marry and have babies with is on that path with someone else, and another to be a virtual witness to it. 
 
 Conventional wisdom, and even science, has it that cutting off contact with an ex makes for a smoother recovery. But nowadays — said in my best granny voice — it’s much more difficult to get distance from an ex. (Funnily enough, my married ex is thousands of miles away — and it was the Internet that allowed our long-distance relationship to exist in the first place.) It isn’t as easy as tearing your rotary phone from the wall. It isn’t even as simple as deleting an ex’s number from your cellphone. There’s Facebook, Twitter, Instagram and the rest of the Internet with which to contend. 
 
 My ex’s live-tweeted marriage reminded me of this. So did my most recent breakup with a man whom I remain connected to via three social media platforms. But then there came yet another reminder this week — a study with a finding that will surprise no one: “Facebook stalking” an ex “may obstruct the process of healing and moving on from a past relationship.” You can no longer pretend that hitting “refresh” on your ex’s profile is helping you “process.” 
 
 The study by Tara C. Marshall, a psychology professor at Brunel University, found that “Facebook surveillance was associated with greater current distress over the breakup, more negative feelings, sexual desire, and longing for the ex-partner, and lower personal growth.” More surprisingly, those who stayed Facebook friends with their ex “reported less negative feelings, sexual desire, and longing for the former partner” — but they were “lower in personal growth.” Marshall suggests this may be because “unbidden exposure to the potentially banal status updates, comments, and photos of an ex-partner through remaining Facebook friends may have decreased any residual attraction to the ex-partner,” whereas defriended exes “remain shrouded in an alluring mystique.”
– What with Facebook, Flickr, and other fine venues for stalking "exes," breakups aren't nearly as final as they once were. But for your own good, please stop following them around cyberspace. "Conventional wisdom, and even science, has it that cutting off contact with an ex makes for a smoother recovery," writes Tracy Clark-Flory at Salon. And she knows the struggle all too well, having tracked an ex from Flickr to Twitter until she realized that the ring on his finger wasn't "merely an engagement ring." Not only was he already married, but Clark-Flory had to see a live-tweeted photo of him standing in the aisle. "It’s one thing to realize that the man you once wanted to marry" has moved on, she writes, "and another to be a virtual witness to it." Clark-Flory digs up studies to make her case, like one that finds "Facebook stalking ... may obstruct the process of healing" and another in which 30% of college students admit to posting status updates "to taunt or hurt" an ex. The only problem: "It’s never been easier to secretly keep tabs on exes," writes Clark-Flory, "and it’s never been harder not to."
