Differential Effects of Active Social Media Use on General Trait and Online-Specific State-FoMO: Moderating Effects of Passive Social Media Use

Introduction

Over the past few years, the phenomenon of fear of missing out (FoMO) has received increasing scientific attention. The characteristics of FoMO include a fear of missing out on others’ pleasurable experiences, a strong motivation to know the movements of others, and frequent checking of mobile phones.¹ An increasing corpus of research has indicated that the FoMO is prevalent in both online and offline settings and is linked to multiple negative consequences (see,² for a review). Individuals with high FoMO levels are more at risk for problem behaviors such as mobile phone addiction,³ problematic social media,⁴ and phubbing (snubbing a social partner by using the phone).⁵ FoMO has also been related to internalized problems in individuals, such as disturbed sleep,⁶ dissatisfaction with life,⁷ diminished well-being,⁸ anxiety,⁹ and depression.¹⁰ Therefore, understanding the psychological mechanisms that create FoMO has become a significant focus of researchers who are interested in digital health.

The link between social media and the FoMO is one of the most discussed topics by researchers.^1,2 Social media has become an essential instrument among the general public, especially young people, to socialize and entertain themselves in the digital era. A nationwide (n=5118) survey showed that 99.39% of Chinese college students use social media daily, and 74.69% spend more than 4 hours daily.¹¹ This survey additionally revealed that WeChat (95.75%) is the most popular social media platform among Chinese college students, followed by QQ (72.25%), TikTok (65.57%), and Sina Weibo (35.91%). Increasingly research has shown that the use of social media increases the FoMO.^12–15 However, the limitation of these studies is that evaluating overall levels of social media use or FoMO, does not sufficiently reveal the essential link between the two.¹⁶

First, as the research progressed, two main categories of social media activity have been identified: active social media use (ASMU) and passive social media use (PSMU).¹⁷ ASMU is defined as activities that promote direct communication with others, including behaviors such as posting, sharing links, commenting on updates, and initiating chats with friends.¹⁷ PSMU refers to behaviors that lack communicative interaction, such as merely browsing information.¹⁷ The research illustrated that PSMU explains the negative consequences of using social media, such as depression,¹⁸ decreased subjective well-being,¹⁹ harmful social comparisons,²⁰ and FoMO.²¹ Instead, ASMU explains the beneficial effects of social media, such as satisfaction with life,²² reduced loneliness,²³ and more social support.²⁴ There are some studies on PSMU and FoMO.^15,21,25 However, little attention has been paid to ASMU and FoMO, and only one study showed that active WeChat interactions reduced FoMO via reduced upward social comparison.²⁶ Therefore, the relationship between ASMU and FoMO is the concern of this study.

Secondly, FoMO has also been conceptualized a two-dimensional construct, which consists general trait-FoMO and online-specific state-FoMO.¹⁶ Triat-FoMO and state-FoMO are both closely related and distinctly different. Some studies have shown that trait-FoMO is more influenced by individual psychological factors,^27,28 while state-FoMO is more related to social media use behavior.^29,30 So, what are the effects of ASMU on trait- and state-FoMO? In addition, according to the active-passive social media use model,^17,31 individuals do not show only ASMU or only PSMU; both can exist simultaneously, and the psychological impact of ASMU depends on PSMU.³¹ Hence, whether the level of PSMU impacts the relationship between ASMU and the two types of FoMO is also an urgent question. Therefore, it is necessary to explore the complex relationship between the two types of social media use and the two types of FoMO. This approach has the potential to illuminate the full scope of social media’s effect on FoMO and provide more specific recommendations for how to counteract the phenomenon in practice.

In this study, we integrate ASMU, PSMU, trait-FoMO, and state-FoMO into a model that including both indirect and moderating effects to explore their possible interrelationships. Below, we first introduce the trait-state fear of missing out theory, with emphasis on the distinction between trait-FoMO and state-FoMO, as this will be key to understanding the main idea of this article. We then propose some possible hypotheses for the relationships based on the theories, and findings of related studies.

Literature Review and Hypotheses

Trait-State Fear of Missing Out Theory

FoMO was originally conceptualized as a dispositional trait, and defined as a generalized anxiety brought on by worry that one is missing out on others’ pleasurable experiences.³² Recently, FoMO was considered to have both trait-FoMO and state-FoMO forms.²⁷ General trait-FoMO is defined in a manner compatible with Przybylski et al.³² State-FoMO, also known as online-specific FoMO, refers to an unsteady cognitive bias that appears during online activities like social media use.²⁷ Conceptually, trait-FoMO is a cognitive propensity that exhibits a jealous state of mind³³ as well as a psychological need deficit,²⁷ whereas state-FoMO is considered less psychological problems than trait-FoMO. The results of several recent studies showed that anxiety and depression were significantly positively associated with trait-FoMO, but not with state-FoMO;^5,27 the levels of mental health negatively predicted trait-FoMO, but did not predict state-FoMO.²⁸ Furthermore, state-FoMO was shown more associated with social media use behavior than trait-FoMO.^29,30

In addition, it should be noted that trait-FoMO, demonstrates some stability while also being influenced by situational and interpersonal factors, similar to other characteristics that are relatively stable, such as self-esteem.^27,32 In fact, empirical studies have demonstrated that the satisfaction of psychological needs is associated with lower trait-FoMO.^32,34 Buglass et al¹² found that self-esteem predicted a decrease in trait-FoMO six months later. Other studies have found high social support to be associated with lower trait-FoMO.^35,36

ASMU, Trait-FoMO, and State-FoMO

In the previous formulation, the contrasts between trait-FoMO and state-FoMO were highlighted because it is possible that they have different connections with the ASMU. We hypothesized that, as positive social behavior, ASMU promotes good interpersonal relationships and can be beneficial for trait-FoMO alleviation. On the other hand, as social media use behavior, frequent use may trigger state-FoMO, which in turn has a facilitating effect on trait-FoMO. In conclusion, we would like to emphasize that ASMU may be a double-edged sword. ASMU has positive effects but also generates some negative social media-related perceptions in the process of use, which may also have negative effects on the psychological state of individuals.

ASMU may be associated with reduced trait-FoMO. Firstly, ASMU behaviors are positive ways to connect with others online, are thought to maintain positive relationships between individuals and acquaintances, and to acquire social support.¹⁷ Evidence from both longitudinal and experimental studies supports this idea. Deters and Mehl³⁷ found that experimentally induced status update activity increased individuals’ sense of closeness to their friends. Online self-disclosure behavior was found to positively predict friendship quality six months later.³⁸ And Manago et al³⁹ used a diary survey method to find that time spent communicating with friends online predicted adolescents’ friend closeness. Several other studies have demonstrated the longitudinal effects of ASMU on social support.^40,41

Secondly, Przybylski et al³² suggested that interpersonal factors can determine trait-FoMO. Previous research has demonstrated that good interpersonal relationships and higher friend support are protective factors for trait-FoMO.^35,36,42 Hence, it can be inferred that ASMU may be associated with a reduction in trait-FoMO. In addition, ASMU is shown to be linked to satisfied need to belong,⁴³ reduced loneliness and depression,⁴¹ and increased life satisfaction and self-esteem.⁴⁴ These positive psychological experiences may lead to less worry about others having rewarding experiences than oneself.^28,32

ASMU may be associated not only with decreased trait-FoMO, but also with increased state-FoMO. State-FoMO is a social media-related cognitive bias,^27,28 is triggered by frequent social media use. Media effects theories suggest that media use behavior has a substantial impact on media-related cognitions.^45,46 Although ASMU is a positive behavior that serves multiple psychosocial functions, the essential property of social media may nevertheless trigger state-FoMO. First, because of the technological advances in online socialization,⁴⁷ individuals can start online conversations and receive updates at any time. This property of social media can increase connections and sharing but also increase awareness of missed activities.²⁷ Second, online socialization is characterized by asynchronicity.⁴⁷ This may be a positive feature in that it gives the social media user time to choose appropriate responses and to avoid interpersonal damage from making inappropriate responses.⁴⁸ However, asynchronous communication may increase an individuals’ anxiety while waiting for the other party to respond.⁴⁹ This may prompt the user to check social media more often to alleviate the anxiety of missing messages,⁵⁰ which is a typical expression of state-FoMO.²⁷ Thus, frequent ASMU is associated with an increase in state-FoMO, further increasing trait-FoMO. Given these considerations, we proposed that:

Hypothesis 1. ASMU predicts lower trait FOMO (H1),

ASMU, PSMU, Trait-FoMO, and State-FoMO

As mentioned earlier, the psychological effects of an individual’s ASMU may differ depending on the level of their PSMU.^17,31 Hence, PSMU may influence the relationship between ASMU and trait-FoMO as well as state-FoMO.

Cross-sectional studies demonstrate a positive correlation between PSMU and trait-FoMO.^15,51 One longitudinal study of university students showed that PSMU was associated with trait-FoMO eight month later.²¹ Researchers have argued that PSMU increases trait-FoMO mainly because of frequent upward social comparisons^4,52 that generate negative self-perceptions or feelings such as “others are happier than I am”.⁵³ Numerous research additionally indicated that PSMU is associated with a higher frequency of social comparisons.^15,20,26,54 Thus, individuals may reduce their trait-FoMO by actively connecting, but if they also spend time engaged in PSMU, they could make more upward social comparisons and experience jealousy¹⁸ and anxiety,¹⁵ thus increasing their trait-FoMO. The longitudinal effect of PSMU on state-FoMO was also confirmed.²⁵ Therefore, the positive correlation between ASMU and state-FoMO may be strengthened by PSMU. In addition, although an interaction between ASMU and PSMU in predicting FoMO has not been tested in empirical studies, prior work revealed that upward social comparison weakened the association between social media communication and loneliness,⁵⁵ which provides indirect evidence that PSMU may moderate the relationship between ASMU and trait-FoMO as well as state-FoMO. Given this analysis, the present study proposes that:

Hypothesis 3 The association between ASMU and trait-FoMO is moderated by PSMU; this relation is stronger at lower levels of PSMU.

Present Study

The purpose of this research was to gain more knowledge for understanding the connection between engaging in activities on social media and experiencing FoMO. Based on the active-passive model of social media use and the concept of trait-state dimensions of FoMO, we constructed and tested a structural equation model of the mechanisms and moderators of the associations among ASMU, PSMU, trait-FoMO, and state-FoMO. See Figure 1. The research addressed three questions: (1) Does ASMU inhibit trait-FoMO formation while increased state-FoMO? (2) Does PSMU weakened the inhibitory effect of ASMU on trait-FoMO? (3) Does PSMU strengthen the possibility of ASMU increasing state-FoMO. Answering these questions will contribute to comprehending better how social media affects FoMO.

Materials and Methods

Participants

The data were collected in Mid-October 2021. A total of 431 college students with more than one year of experience using social media were selected for the study by convenience sampling. The students were from three colleges and universities in Jiangxi Province, China. Questionnaires were completed online. After eliminating invalid questionnaires (very short completion time or inconsistent responses), there were 394 participants whose data were included in the analyses. Of these participants, 138 (35.0%) were males and 256 (65.0%) were females, ranging in age from 18 to 25 years (M=20.16; SD=1.32). On average, 40 participants (10.0%) used social media for less than 1 hour per day, 89 (22.6%) for 1–2 hours, 66 (16.8%) for 2–3 hours, 53 (13.5%) for 3–4 hours, 61 (15.5%) for 4–5 hours, and 85 (21.6%) for more than 5 hours.

Procedure

We first contacted all the class teachers to obtain their consent. The survey was conducted in the classroom, using an online anonymous questionnaire link (a Chinese survey website: www.wjx.cn). Graduate students in applied psychology clarified the purpose of the survey, emphasizing the principles of careful completion, voluntariness, and confidentiality. The anonymous questionnaires were completed within 15 minutes. Each participant volunteered to participate in this study. This study was conducted under the ethical standards set forth in the 2013 Helsinki Declaration.

Measures

Active and Passive Social Media Use

The Surveillance Use Scale⁵⁶ was used to measure the levels of ASMU and PSMU. The scale consists of eight questions, the first four of which measure ASMU (e.g “actively contacting friends”), and the last four of which measure PSMU (e.g “read status updates from friends”). Liu et al²⁰ revised the Chinese version of the scale with good fit indices and good construct validity. The scale employs a Likert scale with 5 points, with 1 representing “never” and 5 representing “frequent”. Higher scores indicate higher ASMU or PSMU. Our sample’s Cronbach’s alpha for the ASMU and PSMU subscales was 0.71 and 0.81, respectively. The average variance extracted (AVE) for the ASMU and PSMU was 0.42 and 0.55, respectively.

Trait-State Fear of Missing Out

This study used the Chinese version of the Trait-State Fear of Missing Out Scale. The scale was originally developed by Wegmann et al²⁷ and was translated and revised by Li et al.³⁰ The scale consists of 12 items on Trait-FoMO (e.g “I am afraid that other people have more exciting experiences than I do”) and State-FoMO (e.g “I keep checking my smartphone so I wouldn’t miss anything”). The two subscales consist of 5 and 7 items, respectively. Participants used a Likert scale that ranged from 1 (totally disagree) to 5 (totally agree) points to score each item. Scores that are higher suggest a higher presence of FoMO. Our sample’s Cronbach’s alpha was 0.84 for the trait-FoMO scale and 0.86 for the state-FoMO scale. The AVE for the trait-FoMO and state-FoMO was 0.50 and 0.42, respectively.

Covariates

The control variables included average daily social media use (hours), gender, and age, as these factors have been shown to be significantly associated with FoMO.^14,32,57

Data Analysis

Because the data were gathered through self-reporting, we first checked common method bias using Harman’s single-factor test. The first factor explained 29.3% of the variance, indicating that common method bias was not a serious issue.⁵⁸ Next, descriptive statistics and correlations were generated in SPSS 21.0. AMOS 23.0 was used to test the hypothesized model, in the following steps: (1) tested the measurement model using confirmatory factor analysis (CFA), oblique CFA for all latent variables in the model, using AMOS 23.0, showed an acceptable fit⁵⁹ (χ²/df = 3.033, p=0.000, CFI = 0.907, TLI =0.901, SRMR =0.079, RMSEA =0.072, [90% CI: 0.065, 0.079]), allowing further SEM analysis.(2) Constructed and tested a structural equation model of the relationships among the independent and dependent variables. We used the factorial approach to parcel⁶⁰ the three latent variables of ASMU and trait- and state-FoMO into two indicators, respectively. After centering the ASMU and PSMU indicators, the interaction term indicators for ASMU and PSMU were constructed.⁶¹ With the addition of the control variable (time spent on social media), the model included four latent and 10 observed variables. (3) Used the bias-corrected nonparametric percentile bootstrap method (2000 draws) to test mediating and moderating effects.

Using Cronbach’s alpha coefficient to figure out how reliable a scale is, where >0.70 implies the reliability is good.⁶² If the AVE is more than 0.36, the convergent validity is acceptable, and if it is greater than 0.5, it is ideal.⁶³ In this research, we used the maximum likelihood (ML) method to process the models, and the model fit was evaluated based on the size of the following indices: comparative fit index (CFI), Tucker Lewis index (TLI), root-mean-square error of approximation (RMSEA), and standardized root mean square residual (SRMR). According to Kenny’s⁵⁹ suggestions, CFI, TLI>0.9 indicates that the model and data attain an acceptable fit, and >0.95 indicates an ideal fit. The RMSEA should report 90% confidence intervals (CI), an ideal range with a lower limit close to 0 and an upper limit below 0.1, and SRMR < 0.08 is considered a good fit.

Results

Correlation Between Variables and Descriptive Analysis

Table 1 presents the means, standard deviations and correlation matrix of all observed variables. ASMU was not significantly correlated with trait-FoMO, but was positively correlated with state-FoMO and PSMU. PSMU was positively associated with both trait-FoMO and state-FoMO. Gender and age were not significantly associated with any primary variables, and therefore these two factors were not controlled for in the hypothesis testing. Daily social media use time was significantly and positively associated with state-FoMO, therefore, it will be controlled for in the hypothesis testing.

Structural Model Testing

First, it is important to note that even though the correlation between ASMU and trait-FoMO was not significant, the existence of a “suppressing effect” cannot be ruled out.^64,65 It is possible for the total effect to be suppressed and its absolute value to be lower than expected if the sign of the indirect effect is the opposite of that of the direct effect.^64,65 State-FoMO is positively correlated with trait FoMO and ASMU, which provides a possibility that state-FoMO plays a suppressing role between ASMU and trait FoMO. Therefore, the following structural equation model test will be further considered.

Controlling for daily social media use time, the SEM analysis demonstrated that the proposed research model fit the data well:⁵⁹ χ²/df =1.491, p=0.064, CFI=0.993, TLI=0.987, SRMR=0.021, RMSEA=0.035, [90% CI: 0.000, 0.059].

The associations among variables in the structural model are reported as standardized values and are shown in Figure 2. Confidence intervals are considered significant when they do not contain zero. First, ASMU significantly positively predicted state-FoMO (β=0.19, p<0.05, 95% confidence interval [CI] [0.029, 0.354]), and state-FoMO significantly positively predicted trait-FoMO (β=0.63, p<0.01, 95% CI [0.505, 0.735]). H2 were supported. Interestingly, in the correlational analysis the association between ASMU and trait FoMO was positive and non-significant (r=0.08, p>0.05), but in support of H1, in the structural model ASMU significantly negatively predicted trait-FoMO (β=−0.19, p<0.01, 95% CI [−0.313, −0.070]). This demonstrates that state-FoMO suppressed the relation between ASMU and trait-FoMO.^57,64,65 In addition, consistent with H3, the interaction of ASMU and PSMU (estimated by standardization) significantly predicted trait-FoMO (β=0.12, p<0.05, 95% CI [0.035, 0.206]). Nonetheless, there was no significant predictive effect of the interaction on state-FoMO (β=0.07, p>0.05, 95% CI [−0.052, 0.202]), and therefore H4 was not supported.

Figure 2 Final standardized parameter values of the mode. N=394, *p<0.05, **p<0.01, ***p<0.001. For brevity, the control variables are not shown.

In order to more clearly explain the interaction between ASMU and PSMU on trait-FoMO, the PSMU scores were separated into two groups: high level (one standard deviation above the mean) and low level (one standard deviation below the mean), and using simple slopes test to examine the effect of ASMU on Trait-FoMO at the two levels of PSMU. Figure 3 shows the results. At a low level of PSMU, ASMU was found to have a statistically significant predictive effect on the trait-FoMO. (β=−0.31, p<0.01, 95% CI [−0.493, −0.148]) but not at a high level of PSMU (β=−0.07, p>0.05, 95% CI [−0.191, 0.039]).

Figure 3 PSMU moderated the relationship between ASMU and trait-FoMO.

Discussion

It has been assumed that social media use increases FoMO.^12,13 However, this explanation may be inadequate. Consistent with our hypotheses, the results suggested that using social media could lead to an increase in FoMO but also reduce some aspects of FoMO. This more complex understanding was possible because we made a distinction between active and passive social media use, as well as between trait and state FoMO.We used structural equation modeling to find that ASMU was associated with lower trait-FoMO, but this association was suppressed by state-FoMO. PSMU moderated the direct effect of ASMU on trait-FoMO, with the effect being significant in low-PSMU individuals but not in high-PSMU persons. The current research demonstrated ASMU’s dual-edged effects on FoMO, which manifests as a decrease in trait-FoMO and an increase in state-FoMO.

ASMU and Trait-FoMO:Suppressing Effect of State-FoMO

Contrary to our expectations, the bivariate correlations showed no significant association between ASMU and trait-FoMO. Pang²⁶ also found that active WeChat interaction was not correlated with trait-FoMO, and was confused by the unexpected result. According to some scholars,^64,65 this condition is possibly to be a case of suppressing effect, where the main effect is suppressed. Further structural equation modeling results revealed that ASMU significantly and negatively predicted trait-FoMO, and also positively predicted trait-FoMO through the indirect effect of state-FoMO. Indirect and direct effects have opposite signs, indicating a suppressing effect. It follows that ASMU has a positive predictive effect on trait FoMO, but this relationship is suppressed by state-FoMO. This would explain why ASMU failed to predict trait-FoMO.

Previous studies have demonstrated the positive effects of ASMU in reducing negative psychological states and emotions.^22,24,66 Our results suggest that ASMU have an overall positive role in reducing trait-FoMO. The current study provides further evidence of ASMU’s positive effects that were reported in these other studies. Engaging in ASMU, such as chatting with friends and commenting on friends’ updates, is thought to facilitate the establishment, maintenance, and expansion of social relationships and to increase individuals’ sense of connectedness with others.^39,67 Moreover, online self-representation, such as updating one’s status and sharing images, promote access to individual social support.^23,24,68 These behaviors can also improve friendship quality,³⁸ and reduce the occurrence of upward social comparisons.²⁶ Consequently, active social media communication may reduce maladaptive cognitive tendencies such as “I am unpopular and others have more pleasurable experiences than I do”.^15,28 This reduction may occur because active social media use can provide social support and good interpersonal relationships.

In contrast, ASMU positively predicted trait-FoMO through the indirect effect of state-FoMO, suggesting that ASMU can exacerbate trait-FoMO by increasing state-FoMO. The results support the media effects theories,^45,46 which posit that individual media use is an important factor influencing media-related cognitions. Because social media socialization is not limited by time and space, and the channels of communication between people are always open,^47,69 there is a likelihood that some individuals will worry about missing messages.^27,49 Because of the asynchronous nature of social media,⁴⁷ we cannot be sure that when we start a session or post a message, we will get a response right away. Sending messages to others for some purpose and then waiting for spontaneous replies can make users pay more attention on social media.⁴⁹ This may lead to the behavior of frequently checking social media to prevent missing messages.^49,50 This effect may, in the long run, also lead to general anxiety at the prospect of missing out on online and offline social activities.²⁷ Furthermore, in line with Röttinger et al,²⁸ it was shown that state-FoMO is a perception associated with social media use in particular, whereas trait-FoMO may contains more context-independent social comparisons.⁴ This study also responds well to Elhai et al’s¹ call for a distinction between trait and state-FoMO and to their suggestion that more research is necessary to explore these links.

The above findings provide a different perspective for understanding the relationship between social media use and FoMO on the one hand. Social media may not always increase FoMO, because positive, active social media interactions are conducive to alleviating trait-FoMO. On the other hand, the suppressing effect of state-FoMO may also be used to explain the inconsistent results of ASMU with other psychological consequences (eg, loneliness),⁷⁰ which requires to be looked into more in future research.

Moderating Effect of PSMU

Conceptually, researchers have argued that a complex relationship exists between ASMU and PSMU, with the effects produced by one being influenced by the other.^17,31 Therefore, the present study also explored whether the degree of individual PSMU moderated the relationship between ASMU and trait- and state-FoMO. Most previous studies have only examined the separate effects of ASMU or PSMU. This is the first study to test the interaction between ASMU and PSMU in predicting FoMO.

Consistent with our assumption, the level of PSMU moderated the direct predictive effect of ASMU on trait-FoMO. Specifically, This association was not significant in the high PSMU group but was in the low PSMU group. Individuals with high PSMU may have a less clear understanding of themselves compared with individuals with low passive use.²⁰ They may be more prone to jealousy and upward social comparison,^15,18 leading to more concern about missing out on others’ exciting experiences documented on social media.⁴ In addition, individuals with high PSMU tend to have more more negative affective experiences, such as loneliness,⁷¹ stress,⁵¹ and anxiety,⁵⁴ all of which may weaken the attenuating effect of ASMU behaviors on trait-FoMO.

Inconsistent with our hypothesis, PSMU did not moderate the relationship between ASMU and state-FoMO, suggesting that frequent information browsing and interactive social media use may both trigger transient feelings of concern about missing information. The results once again support the trait-state model of FoMO.²⁷ They also support the media effect theories,⁴⁵ which states that state-FoMO is significantly influenced by the characteristics of social media use itself, regardless of whether the use is positive or negative. Therefore, reducing state-FoMO by changing social media’s functional design could be an effective approach in reducing the negative effects of social media use, and researchers are working in this direction.⁷²

Theoretical and Practical Implications

Our findings deepen and expand our understanding of the mechanisms underlying the influence of social media on FoMO. Few research have focused on the relationship between specific social media use behaviors and types of FoMO. This paper investigated the complex association between social media use and FoMO based on the trait-state model of FoMO and the active-passive model of social media use. Structural equation modeling documented suppressing (state-FoMO) and moderating (PSMU) effects, and these results may explain why and when ASMU fails to predict trait FoMO. Furthermore, this study’s demonstration of an inverse relationship between ASMU and trait- and state-FoMO. Consistent with Wegmann et al,²⁷ the result suggests that FoMO is a psychological variable with a multidimensional structure. And it provides new and powerful evidence of the value of distinguishing trait- and state-FoMO. However, it also suggests that ASMU is a double-edged sword. ASMU is a positive behavior, but on the other hand it may generate negative cognitions due to the essential nature of social media.

This research also has practical implications for social media use and FoMO interventions. First, ASMU was associated with lower trait-FoMO; therefore, engagement in ASMU behaviors should be encouraged. Second, considering the suppressing effect of state-FoMO, college students are advised not to place too much importance on timely responses and to minimize social media checking out frequency. Social media companies should also be called upon to design features that are helpful in reducing state-FoMO. In this context, Alutaybi et al⁷² developed a FoMO reduction method that includes technical elements, which is a method worthy of our consideration. Finally, the study found that high PSMU can attenuate the positive effect of ASMU in reducing trait-FoMO, and therefore, interventions that focus on promoting ASMU should also focus on reducing PSMU.

Limitations and Future Research Directions

Despite the strengths of this study, there are several limitations to be addressed in future research. First, a cross-sectional study is a methodological limitation because it cannot document causality. Therefore, future research could employ longitudinal or experimental designs to validate the current findings. Secondly, this study did not distinguish between the active use of different social media platforms. However, a meta-analytic study showed that different types of social media use were differently related to FoMO.¹⁴ Therefore, future studies could further examine the results of this study across different social media platforms. Thirdly, the extent of ASMU and PSMU was measured using self-report. Our measures of ASMU and PSMU have been used in the vast majority of studies to date, but obtaining objective information about the extent of use would increase the validity of the results.

Conclusion

In summary, the current work provides additional details for understanding the relationship between social media and FoMO. It provides evidence that ASMU has different effects on different aspects of FoMO. On the one hand, ASMU is conductive to the alleviation of trait-FoMO. However, it is significant to note that ASMU may also predict higher state-FoMO, which increase the potential for experiencing trait-FoMO. In addition, PSMU weakens the negative predictive effect of ASMU on trait-FoMO. Therefore, a reduction in passive, non-communicative information browsing would be conducive to the alleviation of trait-FoMO by ASMU. These results suggest that an in-depth study of specific social media use patterns and different types of FoMO should be a focus of future digital media research.
