Social comparison orientation and fear of missing out as mediators between self-concept clarity and problematic smartphone use

Unpacking interplays between competitiveness, cooperativeness, and social comparison orientation: A network psychometric approach and replication

Emerging evidence highlights the role of social comparison in competition and cooperation, yet the dynamics among competitiveness, cooperativeness, and social comparison orientation (SCO) remain underexplored. In the present study, we sought to unravel these complex interplays employing graphical Gaussian models (GGMs) and characterize the network structures utilizing cross-sectional data derived from 1073 Chinese participants. A pre-registered independent sample (n = 1348) served to examine the replicability and robustness of our initial findings. Moreover, we explored the Bayesian networks (i.e., directed acyclic graphs) to delve into their probabilistic directed dependencies. Our analysis identified an interpersonal co-opetition network where SCO bridges competitiveness and cooperativeness, emphasizing the key influence of the desire to surpass others. We also found a significant gender effect on the levels of these orientations but not on the network patterns. Additionally, the replication sample offered validation for the resultant network structure and its key nodes. In sum, these findings provide a new insight into the symbiotic relationship between competitiveness and cooperativeness within the framework of social comparison, offering significant theoretical and practical implications.

Linking Self-Esteem to Problematic Mobile Phone Use: A Moderated Mediation Model of Fear of Missing Out and Ruminative Subtypes

Low self-esteem has been identified as a risk factor for problematic mobile phone use (PMPU). However, the magnitude of self-esteem's effect on PMPU varied across different studies. Drawing on the Interaction of Person-Affect-Cognition-Execution model and the response styles theory, this study developed a moderated mediation model to investigate the mediating role of fear of missing out (FoMO) and the moderating roles of ruminative subtypes (i.e., brooding and reflection) in the relationship between self-esteem and PMPU. We conducted a cross-sectional survey among 806 undergraduate students (Mage = 19.35 years, SD = 1.18) using the convenience sampling method. Results showed that self-esteem was negatively associated with PMPU. Mediation analysis revealed that the association between self-esteem and PMPU was mediated by FoMO. Furthermore, moderated mediation analyses revealed that the mediating effect of FoMO was moderated by both brooding and reflection, such that the indirect effect became stronger for individuals with higher levels of brooding/reflection. These findings add to previous research by shedding light on how (i.e., mediation) and under what conditions (i.e., moderation) self-esteem is associated with PMPU and have implications for early prevention and intervention of individual PMPU.

Fear of missing out and problematic social media use: A serial mediation model of social comparison and self-esteem

Background and aim

Fear of Missing Out (FoMO) is consistently associated with problematic social media use (PSMU). Moreover, previous studies have shown a significant association between FoMO, self-esteem, and social comparison. However, there is a lack of studies that have investigated the relationship between, FoMO, social comparison, self-esteem, and PSMU in an integrated model. The present study hypothesized that FoMO may influence PSMU through the serial mediating role of social comparison and self-esteem.

Method

A cross-sectional survey study was conducted comprising 256 Italian university students (74.4% female), aged 18 to 38 years (M = 23.05 years; SD = 3.58). The participants completed an online survey assessing the variables of the study.

Results

Controlling for age and gender, the results showed positive associations between FoMO, social comparison, and PSMU, and a negative association between FoMO and self-esteem. Self-esteem was also negatively associated with PSMU. It was also found that social comparison and self-esteem sequentially mediated the association between FoMO and PSMU.

Conclusions

The present study contributes to understanding the mechanisms that underline the complex effects of FoMO on PSMU.

The relationship between self-concept clarity, athletic identity, athlete engagement and the mediating roles of quality of life and smartphone use in Chinese youth athletes

Background

Youth athletes represent the future of competitive sports, so examining their commitment to sport is critical. This study investigated the impacts of self-concept clarity and athletic identity on athlete engagement among Chinese youth athletes, and the mediating roles of quality of life and smartphone use.

Methods

410 youth athletes from sports schools completed an online cross-sectional survey measuring self-concept clarity, athletic identity, quality of life, smartphone use, and athlete engagement. We used convenience sampling. Instruments included validated scales like the Self-Concept Clarity Scale.

Results

The direct effect of self-concept clarity and athlete engagement in youth athletes was not significant (β = 0.04, p = 0.344), but there was a direct effect of athletic identity and athlete engagement (β = 0.61, p < 0.05). Quality of life mediated the relationships between self-concept clarity(indirect effect = -0.054, 95 % CI = -0.114, -0.019), athletic identity(indirect effect = 0.202, 95 % CI = 0.114, 0.349) and athlete engagement.

Conclusions

This study helps address gaps in understanding athlete engagement in youth athletes. The mediation model provides insights to improve self-concept clarity, athletic identity and quality of life to motivate greater engagement in youth athletes.

Intolerance of uncertainty fuels preservice teachers' smartphone dependence through rumination and anxiety during the COVID-19 pandemic: A cross-sectional study

Objectives

We aimed to explore the relationship among intolerance of uncertainty (IU), rumination, anxiety, and smartphone dependence (SPD) in preservice teachers during the COVID-19 pandemic.

Methods

Two cross-sectional studies were conducted with Chinese preservice teachers, using questionnaires on IU, rumination, anxiety, and SPD. Data were analyzed using AMOS 24.0 and SPSS 25.0, and the mediating mechanism was tested using the macro program Model 6. Study 1 recruited participants who were forcibly sequestered in a university due to an anti-epidemic policy during the COVID-19 crisis. Study 2 was surveyed online from different universities to replicate and enhance the reliability of Study 1 finding.

Results

Study 1 (N = 553, Mage = 20.8 ± 2.3, 30.0% female) and Study 2 (N = 1610, Mage = 21.1 ± 2.1, 51.4% female) both found that IU affected SPD through the independent mediators of rumination and anxiety, as well as the chain mediation of rumination→ anxiety. In Study 1, the indirect effect of IU on SPD was significant through rumination (β = 0.16, 95% CI [0.03, 0.06]), anxiety (β = 0.11, 95% CI [0.03, 0.06]), and the chain mediation (β = 0.02, 95% CI [0.01, 0.04]); in Study 2, the indirect effect of IU on SPD was significant through rumination (β = 0.08, 95% CI [0.05, 0.11]), anxiety (β = 0.10, 95% CI [0.08, 0.13]), and the chain mediation (β = 0.02, 95% CI [0.02, 0.03]).

Conclusion

Two cross-sectional studies found that preservice teachers' SPD is indirectly connected to IU, mediated by rumination and anxiety, and weakly mediated by the chain mediation of rumination and anxiety. Our findings may help educators understand the impact of anti-epidemic policies on preservice teachers and possible inclusive later interventions.

The Role of Perfectionistic Self-Presentation and Problematic Instagram Use in the Relationship Between Self-Concept Clarity and Body Disconnection: A Serial Mediation Model

By combining authors who hypothesized that modern technology has greatly increased people's ability and people's possibility to distance themselves from their embodied awareness and those who have shown that communication through social media is more congenial to people with a tendency towards perfectionistic self-presentation (PSP), this study analyses the influence of self-concept clarity (SCC) in bodily dissociation (BD) and hypothesizes that people with a low SCC are more prone to BD and that PSP and problematic Instagram use (PIU) may play a serial mediating role in this relationship. Two hundred and 19 women (M_age = 31.8 ± 11.25) completed an online survey that included the Italian-validated versions of the Perfectionistic Self-Presentation Scale, the Scale of Body Connection and the Bergen Facebook Scale modified for Instagram use. A Serial Mediation Model (Hayes's PROCESS Model 6) shows that both PSP and PIU significantly serially mediate the association between SCC and BD (β = -.025 SE = .011, 95% CI = [-.0498, -.0070]) and that there is a mediating effect of PIU between SCC and BD (β = -.04 SE = .020, 95% CI = [-.0865, -.0098]), but no mediating effect of PSP between SCC and BD was found (β = -.052 SE = .031, 95% CI = [-.1184, +.0039]). A possible explanation is that people with low SCC try to avoid others noticing their imperfections because they fail to integrate it into their self-concept and tend to use Instagram in a problematic way because this tool allows them to largely control the information they share. This use, in turn, alters their state of mind-body connection and this increases the disconnection from one's bodily sensations. The absence of mediation by the PSP between SCC and BD and the presence of PIU mediation between SCC and BD underlines the importance of technology in this relationship. The implications and limitations of this study will be discussed.

Cumulative childhood trauma and mobile phone addiction among chinese college students: role of self-esteem and self-concept clarity as serial mediators

Mobile phones have become an indispensable part of people's lives, and their use has been exacerbated by the COVID-19 pandemic. However, mobile phone addiction has also become a growing concern. This study investigates how cumulative childhood trauma relates to mobile phone addiction among Chinese college students, and the subsequent role of self-esteem and self-concept clarity. A sample of Chinese college students (N = 620) were investigated using the Childhood Trauma Questionnaire-Short Form, the Mobile Phone Addiction Tendency Scale, the Rosenberg Self-Esteem Scale, and the Self-Concept Clarity Scale. The results showed that: (1) cumulative childhood trauma significantly and positively predicted mobile phone addiction among college students; (2) self-esteem mediated the association between cumulative childhood trauma and mobile phone addiction; and (3) self-esteem and self-concept clarity had a sequential mediating effect on the relationship between cumulative childhood trauma and mobile phone addiction. Thus, this study is a reminder to focus on the combined role of multiple adverse experiences and self-system factors in the intervention of mobile phone addiction.

Instagram, risky drinking and main health effects in Spanish adolescents in the COVID-19 pandemic. A qualitative study

INTRODUCTION

The aim of this study was to analyze the relationship between Instagram, alcohol consumption and the impact on adolescent health during the COVID-19 pandemic.

DESIGN AND SAMPLE

A qualitative study was carried out with 13 focus groups, involving 38 interviews. The fieldwork was conducted between January and December 2021 using a semi-structured script with three main categories. The research was carried out by a team specialized in adolescent risks and qualitative research.

RESULTS

Three main categories were established: (1) The COVID-19 pandemic, Instagram and Risky Drinking, (2) Risk prevention and control strategies and (3) Effects on health. The participants (n = 118) reported greater alcohol consumption among Instagram users, either because this social media platform was used to spread the practice of alcohol consumption, or because they were affected by the content posted by digital marketers, Instagrammers, and/or contacts on Instagram. More than half of the sample (67.8%) had health problems (loss of control, headaches, difficulty in breathing, trembling, anxiety attacks, vomiting, tiredness, blackouts, and absence seizures), of whom 35% required urgent attention from their parents and/or the health services.

CONCLUSIONS

Further research is needed to prevent risky drinking related to the use of social networking sites (SNSs) and its main health effects.

Fear of missing out (FOMO) associates with reduced cortical thickness in core regions of the posterior default mode network and higher levels of problematic smartphone and social media use

BACKGROUND AND AIMS

Fear of missing out (FOMO) promotes the desire or urge to stay continuously connected with a social reference group and updated on their activities, which may result in escalating and potentially addictive smartphone and social media use. The present study aimed to determine whether the neurobiological basis of FOMO encompasses core regions of the reward circuitry or social brain, and associations with levels of problematic smartphone or social media use.

METHODS

We capitalized on a dimensional neuroimaging approach to examine cortical thickness and subcortical volume associations in a sample of healthy young individuals (n = 167). Meta-analytic network and behavioral decoding analyses were employed to further characterize the identified regions.

RESULTS

Higher levels of FOMO associated with lower cortical thickness in the right precuneus. In contrast, no associations between FOMO and variations in striatal morphology were observed. Meta-analytic decoding revealed that the identified precuneus region exhibited a strong functional interaction with the default mode network (DMN) engaged in social cognitive and self-referential domains.

DISCUSSION AND CONCLUSIONS

Together the present findings suggest that individual variations in FOMO are associated with the brain structural architecture of the right precuneus, a core hub within a large-scale functional network resembling the DMN and involved in social and self-referential processes. FOMO may promote escalating social media and smartphone use via social and self-referential processes rather than reward-related processes per se.

The double-edged sword effects of active social media use on loneliness: The roles of interpersonal satisfaction and fear of missing out

Introduction

Social media' impact on loneliness has attracted widespread scholarly attention. One hypothesis is that active social media use (ASMU) is associated with a decrease in loneliness. However, several empirical studies did not find a significant correlation between ASMU and loneliness, and ASMU may even increase loneliness. This study explored the mechanism of the double-edged sword effects of ASMU on loneliness.

Methods

Data were collected through convenience sampling from three universities in China. A total of 454 Chinese college social media users (Mean age 19.75 ± 1.33; 59.92% female) completed an online questionnaire.

Results

ASMU was positively related to interpersonal relationship satisfaction, which was negatively related to general trait-fear of missing out (FoMO) and loneliness. Further structural equation modeling (SEM) analysis showed that ASMU could negatively predict loneliness through the mediation pathways of interpersonal satisfaction and "Interpersonal satisfaction → Trait-FoMO." At the same time, ASMU was also positively associated with online-specific state-FoMO, which was positively associated with trait-FoMO and loneliness. Further SEM analysis found no mediation effect of state-FoMO between ASMU and loneliness, but state-FoMO and traitFoMO sequentially mediate the relationship between ASMU and loneliness.

Discussion

This study indicates that ASMU may increase and decrease loneliness. Interpersonal satisfaction and FoMO explained the double-edged mechanism of ASMU on loneliness. These findings contribute to dialectically understanding the effectiveness of active social media use and provide theoretical guidance for promoting the beneficial aspects of social media while weakening its harmful consequences.

Smartphone addiction and phubbing behavior among university students: A moderated mediation model by fear of missing out, social comparison, and loneliness

Introduction

This article examines mediators and moderators that may explain the link between smartphone addiction and phubbing behavior using a sample of 794 university students.

Methods

A mediation model was tested to test the hypothesis that social comparison orientation and fear of missing out would mediate the link between smartphone addiction and phubbing behavior. Additionally, a moderated mediation model was leveraged to examine loneliness as a moderator within the hypothesized model. The data collected were analyzed using SPSS.

Results and Discussion

The findings show a significant positive relationship between smartphone addiction and phubbing behavior. The findings confirm the hypothesized associations and reveal that smartphone addiction is positively linked to phubbing behavior. The link, on the other hand, is partially and sequentially mediated by the fear of missing out and social comparison orientation. As a result, both mediators might be regarded as proximal variables of phubbing behavior. Moreover, the associations between both smart addiction and phubbing behaviors as well as social comparison orientation and phubbing behaviors are moderated by loneliness. These two effects were stronger for university students with high loneliness than for those with low loneliness. This study addresses a major gap in the clinical psychology literature through the attempt to explore the relationship between smartphone addiction and increased phubbing behavior among university students.

Peer pressure and adolescent mobile social media addiction: Moderation analysis of self-esteem and self-concept clarity

Background

Social media addiction has increasingly been a critical social problem. We explored the association between peer pressure on mobile phone use and adolescent mobile social media addiction and tested whether self-esteem and self-concept clarity could buffer the effect of peer pressure.

Methods

830 adolescents (M _age = 14.480, SD_age = 1.789) participated in our anonymous cross-sectional questionnaire study.

Results

The results showed that peer pressure significantly predicted adolescent mobile social media addiction. Self-esteem moderated the effect of peer pressure on mobile social media addiction in that peer pressure had a weaker effect for adolescents with higher self-esteem. Self-concept clarity moderated the effect of peer pressure on mobile social media addiction in that peer pressure had a weaker effect for adolescents with higher self-esteem. The two moderators also interact in that the moderation of self-esteem was stronger for adolescents with higher self-concept clarity and the moderation of self-concept clarity for adolescents with higher self-esteem.

Conclusion

The results highlight the critical role of self-esteem and self-concept clarity in buffering the impact of peer pressure on mobile social media addiction. The findings promote a better understanding of how to buffer the undesirable effect of peer pressure and reduce the risk of mobile social media addiction among adolescents.

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

Purpose

Given the prevalence of the fear of missing out (FoMO) phenomenon and the limitations regarding understanding the relationship between social media use and FoMO, this research examines the links that bind different types of social media usage to different aspects of FoMO.

Methods

In the scope of this research, a structural equation modeling was developed to investigate the intricate connections that exist between active social media use (ASMU), passive social media use (PSMU), online-specific state-FoMO, and general trait-FoMO. Data were obtained from 394 Chinese university students (65% female) with experience in social media who completed the Active Social Media Use Scale, Passive Social Media Use Scale, and the Chinese Trait-State Fear of Missing Out Scale.

Results

Bivariate correlations analysis revealed that ASMU was significantly related with state-FoMO but not significantly related with trait-FoMO. Structural equation modeling revealed that ASMU had a significant direct negative predictive effect on trait-FoMO while positive association with trait-FoMO through the indirect effect of State-FoMO, illustrating that ASMU had a suppressing effect on trait-FoMO via state-FoMO. PSMU significantly moderated the direct effect of ASMU on trait-FoMO, and the direct effect was only significant at low levels of PSMU.

Conclusion

This study revealed whether and how social media use is linked to FoMO. Social media may not always increase FoMO, because positive, active social media interactions are conducive to the alleviation of trait-FoMO. However, it is significant to note that active interactions may also predict higher state-FoMO, so moderate social media use needs to be encouraged. In addition, a reduction in passive, non-communicative information browsing would be conducive to the alleviation of trait-FoMO by ASMU.

Further exploration of the psychometric properties of the revised version of the Italian smartphone addiction scale – short version (SAS-SV)

Problematic smartphone use (PSU) is an emerging public and social issue, potentially connected to the significant increase in smartphone applications. Different scales have been designed and developed to identify the risk of smartphone addiction, and the 10-item Smartphone Addiction Scale - Short Version (SAS-SV) is one of the most used instruments to assess the risk of PSU. The main objective of the present study was to provide further psychometric properties of the Italian version of the SAS-SV. The study was conducted with a convenience sample of 858 Italian university students. Parallel and confirmatory factor analyses were performed to confirm if the one-factor structure fitted the data well. In addition, because previous studies have emphasised gender and age differences in the SAS-SV, measurement invariance was also tested. Network analysis, predictive validity, and convergent validity were also explored. The parallel analysis results suggested removing Item 3 (feeling pain) because its factor loading was low, resulting in a nine-item SAS-SV. The measurement invariance showed that the SAS-SV performed similarly for gender and age. However, partial scalar invariance across gender and age was observed. Furthermore, gender differences indicated that more females than males scored higher on SAS-SV. No significant age differences were found. The receiver operating characteristic (ROC) curve results indicated a cut-off of 29 points as the best for the SAS-SV (AUC = 0.85). Moreover, among males, the cut-off was 25 (AUC = 0.84), and among females, the cut-off was 30 (AUC = 0.84). The SAS-SV showed a strong association with problematic social media use (PSMU) and other variables related to smartphone use (e.g., time spent on Facebook, Instagram, and WhatsApp). Overall, the present study results indicate that the nine-item SAS-SV appears to be a valid and reliable instrument to assess PSU risk among Italian university students.

Exploring the Influence of Problematic Mobile Phone Use on Mathematics Anxiety and Mathematics Self-Efficacy: An Empirical Study during the COVID-19 Pandemic

Problematic mobile phone use is a pervasive issue globally and has aroused wide public concerns. Prior studies have indicated that problematic mobile phone use has a series of negative effects on individuals’ physical and mental health. However, the effects on student learning have seldom been investigated. During the COVID-19 pandemic, home quarantine and social distancing have led to individuals’ greater problematic mobile phone use, and it is essential to have a better understanding of individuals’ problematic mobile phone use and its negative effects during this unprecedented period. Given this, the present study investigates the effects of university students’ problematic mobile phone use on mathematics self-efficacy and mathematics anxiety, which play critical roles in mathematics learning. This study collected data from 420 students in March 2022, when a large-scale COVID-19 lockdown took place in Shanghai, China. Structural equation modeling was used to analyze the data. Our findings show that university students’ problematic mobile phone use can significantly impact mathematics anxiety and indirectly—yet considerably—influence mathematics self-efficacy. This study calls for increased public concern regarding students’ problematic mobile phone use during the COVID-19 pandemic.

Fear of missing out and fear of not being up to date: investigating different pathways towards social and process problematic smartphone use

The present study introduces a new construct potentially associated with problematic smartphone use, that is the fear of not being up to date, and tests two serial mediation models, in which it was hypothesised that: (i) metacognitions and social smartphone use would be serial mediators of the relationship between the fear of missing out (FoMO) and problematic smartphone use (PSU); and (ii) metacognitions and process smartphone use would be serial mediators of the relationship between and the fear of not being up to date and PSU. A sample of 364 participants (F = 72.8%; mean age = 36.80 ± 15.32 years; age range: 18–75 years), recruited online, were administered a battery of self-report measures assessing FoMO, the fear of not being up to date, metacognitions about smartphone use, process and social smartphone use, and PSU. The serial mediation effect of metacognitions about smartphone use and process use on the relationship between the fear of not being up to date and PSU was significant (indirect effect = 0.004; 95% CI: [0.0006, 0.009]). Conversely, the serial mediation effect of metacognitions about smartphone use and social use on the relationship between FoMO and PSU was not significant (indirect effect = 0.002; 95% CI: [-0.003, 0.009]). Smartphone social use did not predict PSU. The current study highlights a possible pathway towards process smartphone use via a relatively new phenomenon termed “fear of not being up to date” within a metacognitive framework.

Problematic Smartphone Use and Problematic Social Media Use: The Predictive Role of Self-Construal and the Mediating Effect of Fear Missing Out

Problematic smartphone use (PSU) and problematic social media use (PSMU) are two interrelated constructs which have received significant research attention over the past decade. The present study investigated the relationship between self-construal (distinguished as independent and interdependent), PSU and PSMU with Fear of Missing Out (FoMO) as a mediating variable. The sample comprised 405 Italian students who completed standardized psychometric scales assessing the variables of the study. Bivariate correlations analysis showed that FoMO and independent self-construal was significantly and negatively associated. On the contrary, interdependent self-construal was significantly and positively associated with FoMO, PSU, and PSMU. Mediation analysis showed that FoMO mediated the relationship between self-construal and both PSMU and PSU, but at different levels. The results demonstrated that FoMO full mediated the relationships between interdependent self and PSU, whereas only partial mediation was found between interdependent self and PSMU. Therefore, taking these personality characteristics into account may help reduce dysfunctional behaviour associated with problematic technology use and promote psychological well-being among students. However, it is recommended that further studies replicate the proposed model by including other psychological constructs.

The association between problematic social networking site use, dark triad traits, and emotion dysregulation

BACKGROUND

Social networking sites (SNSs) allow people to socially connect with each other, collaborate, and share information. However, problematic SNS use (PSNSU) may be associated with negative personality traits. The present study investigated the associations between PSNSU, dark triad personality traits, and emotion dysregulation.

METHOD

In the present study, 555 SNS users (Mage = 33.32 years, SD = 10.88) completed an online survey comprising measures of PSNSU, dark triad personality traits, and emotion dysregulation.

RESULTS

Bivariate correlations showed that PSNSU was significantly associated with dark triad traits as well as emotion dysregulation. Structural equation modelling (where the effect of the dark triad traits on PSNSU was mediated by emotion dysregulation) showed that 33.5% of the variance of PSNSU was explained by Machiavellianism, psychopathy, and narcissism.

CONCLUSION

The findings provide suggestive evidence of why PSNSU may occur as a function of the presence of dark triad traits and emotion dysregulation. The study also highlighted the important role that emotion regulation plays in the association between dark triad traits and PSNSU.

Insecure Attachment Styles and Unbalanced Family Functioning as Risk Factors of Problematic Smartphone Use in Spanish Young Adults: A Relative Weight Analysis

Young adulthood is the life stage during which people are more prone to develop problematic smartphone use (PSU). Only one study investigated the relationship among attachment styles, family functioning, and PSU, but thus far, no research has shown the relative importance that such dimensions may have on PSU. The main aim of this study was to analyze to what extent insecure attachment styles and unbalanced family functioning are related to PSU, investigating the specific weight of each dimension in a sample of young adults (N = 301; 82.7% females; Mage = 22.89; SD = 3.02). Participants completed a self-report questionnaire, including the Relationship Questionnaire, the Family Adaptability and Cohesion Evaluation Scale IV, and the Smartphone Addiction Scale. The regression and relative weight analyses results showed that preoccupied attachment style and disengaged, chaotic, and enmeshed family functioning were positively related to PSU. Implications for future research and interventions were discussed.

Dark Triad of Personality and Problematic Smartphone Use: A Preliminary Study on the Mediating Role of Fear of Missing Out

The present study examined whether the relationship between the Dark Triad (DT) of personality and problematic smartphone use (PSU) can be explained by the mediating role of fear of missing out (FoMO). The role of FoMO in this relationship has yet to be examined. A total of 457 participants completed an online survey. Results indicated that males scored high on measures assessing DT of personality, while females scored high on PSU. Structural equation modelling showed that narcissism was directly associated with PSU. FoMO partially mediated the association between narcissism and PSU. Machiavellianism and narcissism were directly associated with FoMO. In the fully mediated model, narcissism (but not Machiavellianism) was still associated with FoMO, and in turn, FoMO was related to PSU. Although preliminary, the results of the present study indicated that Machiavellianism and narcissism might represent antecedents of FoMO, in addition to the Big Five personality traits, and both could be involved in the development of PSU.

An Investigation into Smartphone Addiction with Personality and Sleep Quality among University Students

Over the past two decades, smartphones have become common, and the accompanying devices have also become much more popular and easily accessible worldwide. With the development of smartphones, accompanied by internet facilities, excessive smartphone use or smartphone addiction may cause sleep disturbance and daily dysfunction. This study proposed examining the association between personality traits and smartphone addiction and its effects on sleep disturbance. Four hundred and twenty-two university participants (80 male and 342 female participants) with a mean age of 20.22 years old were recruited in this study. All participants were asked to complete the following questionnaires: Smartphone Addiction Inventory (SPAI), Tri-dimensional personality questionnaire (TPQ), and Chinese Pittsburgh Sleep Questionnaire Index (CPSQI). The results showed that people with a high tendency toward novelty seeking (NS) as a personality trait, compared to those with lower tendency toward NS, are more likely to become addicted to smartphone use. Moreover, those with a stronger trait of being NS and specific impulsivity factor were found to have higher total scores in the SPAI (p < 0.05). In addition, linear regression analysis showed that the individuals with higher scores for withdrawal symptoms on the SPAI and anticipatory worry factor on the TPQ tended to have higher CPSQI total scores (p < 0.05). This information may be useful for prevention in individuals with personality traits making them vulnerable to smartphone addiction and for designing intervention programs to reduce intensive smartphone use and programs to increase capability in managing smartphone use.
