Network analysis of social anxiety and problematic mobile phone use in Chinese adolescents: A longitudinal study

Social anxiety is a common comorbid factor of problematic mobile phone use, but the relationship between them from the inside structure has been underexplored. This two-wave longitudinal study aims to identify the central symptoms of problematic mobile phone use and social anxiety, respectively, as well as the bridge symptoms between the two disorders. Furthermore, this study examined the time and gender differences. A total of 3,294 Chinese adolescents were recruited during two waves (T1: January 2023; T2: August 2023), and completed the questionnaires of social anxiety and problematic mobile phone use. Through network analysis, the results showed that 1) the central symptom of problematic mobile phone use was "loss of control" both at T1 and T2, 2) the central symptom of social anxiety was "fear of negative evaluation" both at T1 and T2, and 3) the bridge symptom between social anxiety and problematic mobile phone use was "withdrawal" both at T1 and T2. Moreover, the network comparison test indicated that the nodes of social anxiety were more strongly associated with "craving", "loss of control", and "negative life consequences" of problematic mobile phone use at T2 than at T1. The nodes of social anxiety were more strongly associated with "negative life consequences" of problematic mobile phone use for boys than for girls, while the "fear of negative evaluation" was more strongly associated with "loss of control" for girls than for boys. These findings provide new scientific basis for interventions targeting adolescents who are susceptible to social anxiety and problematic mobile phone use.

Effects of aerobic exercise or Tai Chi Chuan interventions on problematic mobile phone use and the potential role of intestinal flora: A multi-arm randomized controlled trial

BACKGROUND

Problematic use of mobile phones (PMPU) has been described as a serious public health issue.

METHODS

This study was a parallel three-arm randomized controlled trial and has completed registration (ClinicalTrials.gov Identifier: NCT05843591). Ninety college students with PMPU were randomly assigned to the aerobic exercise group (AE group, n = 30), the Tai Chi Chuan group (TCC group, n = 30), or the wait-list control group (WLC group, n = 30). At the end of the intervention, stool samples from the study participants were collected for biological analysis based on 16 S rDNA amplicon sequencing technology. The primary outcome was addiction symptoms assessed by the Smartphone Addiction Scale-Short Version (SAS-SV). The secondary outcomes are emotional symptoms, physical symptoms, and flora species.

RESULTS

Compared with the WLC group, the AE and TCC groups showed reductions in PMPU levels, physical and mental fatigue, but there was no difference between the two groups. Moreover, the effect of increasing self-esteem embodied in the TCC group was not present in the AE group. Compared to the WLC group, the relative abundance of Bacteroidaceae and Bacteroides were lower in the AE group, while the relative abundance of Erysipelotrichaceae and Alistipes were lower in the TCC group. And the relative abundance of Bacteroidaceae, Bacteroides, and Alistipes were significantly and negatively correlated with the decline in PMPU scores.

CONCLUSION

AE or TCC is an effective, safe and efficient intervention for college students with PMPU, providing some physiological and psychological benefits and having some impact on their intestinal flora.

Psychometric validation of the Chinese version of the desire thinking questionnaire in adolescent mobile phone users

BACKGROUND

Desire thinking is a conscious and voluntary cognitive process that is closely linked to levels of craving and addictive behaviors. The Desire Thinking Questionnaire (DTQ) can be used to measure desire thinking in all age groups as well as in addicts. This measurement has also been translated into several languages. This study aimed to test the psychometric properties of the Chinese version of the DTQ (DTQ-C) among adolescent mobile phone users.

METHODS

One thousand and ninety-seven adolescents who own a mobile phone and are younger than 18 years old completed the DTQ-C and a battery of questionnaires assessing the big five personality traits, negative affect, brooding, self-control, craving, and problematic mobile phone use (PMPU). The psychometric analyses of the DTQ-C were conducted, including exploratory factor analysis (EFA), confirmatory factor analysis (CFA), reliability, and validity analysis.

RESULTS

The EFA revealed a 10-item two-factor structure (i.e., verbal perseveration and imaginal prefiguration) that was confirmed by the CFA. The results of CFA showed fit indexes of χ²/df = 4.83, CFI = 0.967, TLI = 0.954, RMSEA = 0.059, SRMR = 0.032. The total scale had internal consistency reliabilities of 0.93, which demonstrated that DTQ-C presented good reliability. The two dimensions were correlated with PMPU (r_{verbal perseveration} = 0.54; r_{imaginal prefiguration} = 0.45), neuroticism (r_{verbal perseveration} = 0.18; r_{imaginal prefiguration} = 0.14), conscientiousness (r_{verbal perseveration} = -0.19; r_{imaginal prefiguration} = -0.18), depression (r_{verbal perseveration} = 0.22; r_{imaginal prefiguration} = 0.16), anxiety (r_{verbal perseveration} = 0.26; r_{imaginal prefiguration} = 0.22), stress (r_{verbal perseveration} = 0.15; r_{imaginal prefiguration} = 0.10) and self-control (r_{verbal perseveration} = -0.29; r_{imaginal prefiguration} = -0.26), which demonstrated that DTQ-C presented good concurrent validity. The two factors of DTQ-C correlated weakly with brooding (ranging from 0.08 to 0.10). The principal component factor analysis of the two dimensions of desire thinking and craving showed that craving and desire thinking belonged to different dimensions. Both of which showed good divergent validity of desire thinking. Additionally, an examination of incremental validity revealed that two factors were both positively associated with PMPU beyond demographic characteristics, big five personality traits, negative affect, and self-control (B_{verbal perseveration} = 0.49 and B_{imaginal prefiguration} = 0.13).

CONCLUSIONS

It has been found that the 10-item DTQ-C is a reliable and valid measure of desire thinking in Chinese adolescent mobile phone users.

Association of parent-child relationship quality and problematic mobile phone use with non-suicidal self-injury among adolescents

BACKGROUND

Non-suicidal self-injury behavior (NSSI) is a common mental health threat among adolescents. Poor parent-child relationship (PCR) and problematic mobile phone use (PMPU) are risk factors for NSSI. We aimed to explore the impact of PCR quality, PMPU, and their interaction effects on NSSI among adolescents in China, as well as the sex difference.

METHOD

A survey was conducted among school students in 4 provinces in China between 2017 and 2018. The study included 14,500 valid participants. The students' general demographic characteristics was collected, and further data on PCR quality, PMPU, and NSSI were obtained through self-rated questionnaire. Chi-square test, binomial logistic regression models, and the Andersson Excel were used for data analysis.

RESULTS

The 12-month prevalence of NSSI was 27.3%. Lower PCR quality and PMPU were significantly associated with NSSI, respectively. The low PCR + yes PMPU group had the greatest association with NSSI, followed by the high PCR + yes PMPU group, low PCR + no PMPU group. Moreover, in low father-child relationship + yes PMPU group, females had a higher risk of NSSI than males; in high mother-child relationship + yes PMPU group, females had a higher risk of NSSI than males. Additive interaction analysis indicated that mother-child relationship quality and PMPU were associated with increased risks of NSSI, in the subgroup of males.

CONCLUSIONS

The findings underline the importance of simultaneously studying the quality of PCR and PMPU for a comprehensive understanding of NSSI behavior, and especially highlights the significance of maternal relationship quality.

Gender-based differences in interaction effects between childhood maltreatment and problematic mobile phone use on college students' depression and anxiety symptoms

BACKGROUND

Childhood maltreatment and problematic mobile phone use are risk factors for depression and anxiety symptoms among college students. However, how the interaction between the two factors affects depression and anxiety has yet to be validated. This study aimed to investigate the independent and interaction effects of childhood maltreatment and problematic mobile phone use on depression and anxiety among college students and explored gender-based differences in these associations.

METHOD

A cross-sectional study was conducted from October to December 2019. We collected data from 7623 students at two colleges in Hefei and Anqing cities in Anhui Province, China. Multinomial logistic regression models were performed to explore the associations of childhood maltreatment and problematic mobile phone use with depression and anxiety symptoms and their interaction effects on depression and anxiety symptoms.

RESULTS

Childhood maltreatment and problematic mobile phone use were significantly associated with increased risk of depression and anxiety symptoms (P < 0.001). Moreover, following adjustments for covariates, there was a multiplicative interaction between childhood maltreatment and problematic mobile phone use on depression and anxiety symptoms (P < 0.001). Gender-based differences were also observed in the associations. For instance, depression was more common in males and male students with childhood maltreatment were at higher risk of depression-only symptoms.

CONCLUSION

Focusing on childhood maltreatment and problematic mobile phone use could facilitate a reduction in the occurrence of depression and anxiety symptoms in college students. Furthermore, it is necessary to develop gender-targeted intervention strategies.

Is Nomophobia Problematic or Functional? A Perspective from Bifactor Structure

With the extensive use of mobile phones globally, some people engage in excessive or problematic phone use behaviors. However, little is known regarding the latent structure of problematic mobile phone use. The current study employed the Chinese versions of the Nomophobia Questionnaire, Mobile Phone Addiction Tendency Scale, and Depression-Anxiety-Stress Scale-21 to explore the latent psychological structure of problematic mobile phone use and nomophobia and their associations with mental health symptoms. Results showed that a bifactor latent model best fit nomophobia, which contained a general factor and four unique factors involving the fear of being unable to access information, losing convenience, losing contact, and losing one's Internet connection. Results also showed significant correlations among latent factors of nomophobia, problematic mobile phone use, and mental health symptoms. Through these findings, we can conclude that two problematic mobile phone use behaviors share a common factor concerning excessive use, and nomophobia has independent unique factors concerning usable function. This study clarifies the structure of problematic mobile phone use, and it implies that we can distinguish problematic mobile phone use from functional use; further investigation of problematic mobile phone use is warranted.

[Design and validation of a scale to measure nomophobia among children 9-13 years old]

OBJECTIVE

To design and validate a nomophobia scale in children aged 9-13 years.

DESIGN

Cross-sectional descriptive observational study. SITE: The pilot study was carried out in December 2019 with students from a school in Ávila and another in Madrid. The field study was carried out during the months of January to March 2020, collecting data from 592 students from a school in Badajoz and 3 from Ávila.

PARTICIPANTS

Students of both sexes from 4th, 5th and 6th of Primary Education and from 1st and 2nd of Compulsory Secondary Education, from public and private schools.

METHOD

The study has been divided in 2 phases.

PHASE I

consisted of the preparation of a 40-item questionnaire with the advice of a panel of experts. This questionnaire was passed, within the pilot study, to 312 children enrolled in Primary Education or Compulsory Secondary Education. After analyzing the results, the 40-item scale was modified to improve the understanding of the schoolchildren and a field study was carried out with 592 participants.

PHASE II

consisted of an exploratory factorial analysis carried out using the principal components method, which provided the distribution of the items in 7 components. After the confirmatory factorial analysis, the final 32-item scale was defined.

RESULTS

This scale was shown to produce valid and reliable scores.

CONCLUSIONS

The validation of this scale will be useful to identify children at risk of nomophobia, allowing educators, parents and health professionals to detect this phenomenon early in order to prevent pathological smartphone use.

Association between trajectories of problematic mobile phone use and chronotype among Chinese college students

AIMS

This study aimed to describe the prevalence of problematic mobile phone use (PMPU) and chronotype among Chinese college students, estimate PMPU development trajectories, and further examine the effect of PMPU trajectories on chronotype.

DESIGN

In a stratified cluster sampling design, PMPU and chronotype were evaluated in 999 college students from two universities in a 2-year prospective investigation from April 2019 to April 2021, and an investigation was conducted every six months (time 1 ∼ time 5, T1 ∼ T5).

PARTICIPANTS

N = 999 college students (mean age at T1: 18.8 years (SD = 1.2), 37.7% male) took part in the study.

MEASUREMENTS

The Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use (SQAPMPU) and the Pittsburgh Sleep Quality Index (PSQI) were used to assess the PMPU and sleep quality of college students at each time point. The Morning and Evening Questionnaire (MEQ) was adopted to investigate the chronotype of college students at T5.

FINDINGS

The prevalence of PMPU at T1 ∼ T5 was 24.3%, 27.3%, 35.1%, 31.2% and 31.9%, respectively. The prevalence rates of morning types (M-types), neutral types (N-types), and evening types (E-types) were 19.1%, 70.8%, and 10.1%, respectively. Using latent growth mixture modelling, we identified three trajectories of PMPU: low-level (49.5%), moderate-level (38.6%), and high-level score trajectories (11.9%). Multivariate logistic regression analysis results showed that a trajectory with a high score was positively associated with E-types (P < 0.05). After stratification by gender, a high-level score trajectory was positively associated with E-types only among female college students (P < 0.05). There were sex differences in the association between trajectories of PMPU and chronotype.

CONCLUSION

Long-term symptoms of PMPU may be a potential risk factor for circadian rhythm disturbance among college students, and this effect was significantly different between genders.

The influence of alexithymia on problematic mobile phone use among Chinese adolescent students: Multiple mediating roles of social interaction anxiousness and core self-evaluations

BACKGROUND

Alexithymia can lead to problematic mobile phone use (PMPU). However, the underlying mechanisms remain unclear.

METHODS

Drawing on the Interaction of Person-Affect-Cognition-Execution model, the present study tests the mediating effects (parallel and serial) of social interaction anxiety (SIA) and core self-evaluations (CSE) on the relationship between alexithymia and PMPU. We obtained 1267 valid responses from adolescent students (mean age, 20.36, standard deviation, 0.97) from southeast China who completed the Mobile Phone Addiction Index, Toronto Alexithymia-20 Scale, Social Interaction Anxiousness Scale, and Core Self-Evaluation Inventory.

RESULTS

After controlling for demographic variables (i.e., gender) as covariates, the results revealed that: (1) alexithymia had a positive predictive effect on PMPU in adolescent students; (2) SIA and CSE mediated the association between alexithymia and PMPU; and (3) a series of indirect pathways (i.e., from alexithymia to PMPU via SIA and CSE) were detected. Thus, alexithymia can directly affect (parallel mediation) PMPU by increasing SIA and lowering CSE simultaneously. However, alexithymia can also indirectly affect (serial mediation) PMPU by increasing the level of SIA by decreasing CSE.

LIMITATIONS

Data were collected by participant self-report. This method may lead to recall bias. Further, we adopted a cross-sectional rather than an experimental design, thus precluding causal conclusions. Lastly, it would be useful to validate our findings with other age groups outside southeast China.

CONCLUSIONS

The current study findings are conducive to understanding the relationship between alexithymia and PMPU and inspire the prevention and intervention of PMPU.

The Phubbing Scale (PS-8) in the Portuguese population: psychometric properties

Phubbing is defined as ignoring other individuals by using a mobile phone during a face-to-face conversation. The Phubbing Scale (PS) was developed to assess this practice. In this study, we analyze the psychometric properties of the 8-item version of the PS (PS-8) in the Portuguese population, providing validity evidence based on internal structure and on relationships with other variables, and examining item properties, reliability, and measurement invariance across gender. Participants were 391 Portuguese adults (132 men, 259 women) who completed a battery of questionnaires. Confirmatory factor analysis yielded satisfactory goodness-of-fit indices for the two-factor structure (communication disturbance and phone obsession), which was invariant across gender. Item homogeneity and reliability of factor scores (McDonald’s omega) were satisfactory. Validity evidence based on relationships with other variables was provided by positive associations with time spent on the Internet on weekdays and at the weekend, time spent on social networking sites, number of social networks used, Internet addiction, problematic mobile phone use, Facebook intrusion, fear of missing out, and depression. These associations show the addictive component of phubbing and its relationship with mental health. The PS-8 is a short and easy-to-administer scale with adequate psychometric properties for measuring phubbing in the Portuguese population.

Is the relationship between problematic mobile phone use and mental health problems mediated by fear of missing out and escapism?

•

Higher level of problematic mobile phone use was associated with higher level of mental health problems, Fear of Missing Out (FoMO) and escapism.

•

Higher level of mental health problems was associated with higher level of FoMO.

•

Higher level of FoMO and worry was associated with higher level of escapism.

•

The association between problematic mobile phone use and mental health problems was not mediated by FoMO and escapism.

Introduction

Individuals with problematic mobile phone use often report mental health problems, however, little is known about factors which mediate this association. Therefore, the aim of this study was to examine the mediating role of fear of missing out (FoMO) and escapism in an attempt to explain the relationship between problematic mobile phone use and mental health problems.

Method

A total of 235 undergraduate students in Turkey participated in this study. These participants completed a set of questionnaires to measure fear of missing out, problematic mobile phone use, escapism, depression, anxiety, stress, and worry severity.

Results

Participants with a high level of problematic mobile phone use also had a high level of mental health problems, FoMO, and escapism. The association between problematic mobile phone use and mental health problems was not mediated by FoMO and escapism.

Conclusion

Personal characteristics such as emotional regulation and self-regulation need to be examined in future studies in order to determine their potential mediating role in explaining the association between problematic mobile phone use and mental health problems.

Academic procrastination precedes problematic mobile phone use in Chinese adolescents: A longitudinal mediation model of distraction cognitions

Cross-sectional studies have documented a positive association between academic procrastination and problematic mobile phone use (PMPU). However, the specific predictive direction has remained controversial and the potential mechanisms underlying the association have not been rigorously evaluated. According to Davis's cognitive-behavioral model, Brand et al.'s I-PACE model, and procrastination-related theories, academic procrastination and PMPU might have a reciprocal relationship and distraction cognitions might play a mediating role in this process. A total of 633 secondary school students completed three self-report questionnaires at three 6-month intervals over the course of 1.5 years. The cross-lagged panel model results showed that earlier academic procrastination positively predicted subsequent PMPU over time, but the reverse prediction was not stable. Furthermore, distraction cognitions played a mediating role in linking earlier academic procrastination and subsequent PMPU. These findings indicate that academic procrastination precedes PMPU with distraction cognitions as a potential mediator, which contributes to clarifying the controversial relationship and explicating the underlying mechanism. Overall, interventions for academic procrastination may be effective in reducing maladaptive cognitions associated with mobile phones and preventing adolescents from developing PMPU.

Longitudinal relationships among problematic mobile phone use, bedtime procrastination, sleep quality and depressive symptoms in Chinese college students: a cross-lagged panel analysis

BACKGROUND

Cross-sectional and longitudinal studies have found that problematic mobile phone use, bedtime procrastination, sleep quality, and depressive symptoms are strongly associated. However, studies are inconsistent regarding whether problematic mobile phone use predicts depressive symptoms or vice versa, and sleep factors have been infrequently focused on in this regard. In addition, few studies have examined the longitudinal associations and directions of effects between these factors. Therefore, this study aims to explore the longitudinal relationship among problematic mobile phone use, bedtime procrastination, sleep quality, and depressive symptoms in college students.

METHODS

Overall, 1181 college students completed questionnaires on problematic mobile phone use, bedtime procrastination, sleep quality, and depressive symptoms at two time points 12 months apart. A cross-lagged model was used to examine the longitudinal relationship between these factors.

RESULTS

Cross-lagged analyses showed significant bidirectional relationships of problematic mobile phone use with bedtime procrastination and depressive symptoms. Additionally, there were also significant bidirectional relationships of sleep quality with bedtime procrastination and depressive symptoms. Problematic mobile phone use predicted subsequent sleep quality one-way, and bedtime procrastination predicted subsequent depressive symptoms one-way.

CONCLUSIONS

This study further expands our understanding of the longitudinal and bidirectional relationships among problematic mobile phone use, bedtime procrastination, sleep quality and depressive symptoms and helps school mental health educators design targeted interventions to reduce problematic mobile phone use, sleep problems, and depressive symptoms among college students.

Childhood emotional neglect and problematic mobile phone use among Chinese adolescents: A longitudinal moderated mediation model involving school engagement and sensation seeking

BACKGROUND

Childhood emotional neglect has been shown to be associated with a range of emotional, behavioral and social problems. We hypothesized that childhood emotional neglect might predispose adolescents to engage in Problematic Mobile Phone Use (PMPU) as a way to meet their needs for relatedness.

OBJECTIVE

Using a longitudinal design, we aimed to reveal the explanatory mechanism in the association between childhood emotional neglect and PMPU among Chinese adolescents, by testing the mediating effect of school engagement and the moderating effect of sensation seeking.

METHODS

Participants were 1987 Chinese adolescents (56.13 % male; M_age at Wave 1 = 12.32) who completed self-report questionnaires regarding childhood emotional neglect, school engagement, PMPU and sensation seeking at three time points in the course of a year.

RESULTS

The results of structural equation modeling (SEM) showed that retrospective reports of childhood emotional neglect at Wave 1 were positively associated with adolescent PMPU at Wave 3, and school engagement at Wave 2 fully mediated the association. Meanwhile, sensation seeking at Wave 3 moderated the pathway from school engagement to later adolescent PMPU in the mediated model. Specifically, the effect of low school engagement on PMPU was stronger for adolescents who reported high sensation seeking.

CONCLUSION

Identifying the processes by which childhood emotional neglect is associated with adolescent PMPU over time has potential applied value for prevention and intervention.

Arabic version of the Hayling sentence completion test: scale validation, normative data and factors associated with executive functions in a sample of the Lebanese adults

BACKGROUND

This study was conducted for several reasons, primarily because of the lack of an Arabic version of the HSCT that could be beneficial in our clinical practice. Another reason is the need to find potential relationships between various factors with executive functions, especially problematic mobile phone use as suggested by many previous studies, since smartphones have become, nowadays, a daily companion of people from all generations. Thus, it is important to conduct this study in Lebanon to be adapted to the ideas, customs and social behavior of the Lebanese citizens. Hence, the objectives of the current study are to use the Arabic version of the HSCT in healthy community-dwelling Arabic-speaking adults in Lebanon, to check its validity compared to other versions of the test, as well as to identify risk factors that might affect the executive functions in these adults.

METHODS

Between August-December 2019, 350 participants were randomly selected. The Arabic version of the HSCT, divided into automatic and inhibition conditions, was used; in each condition, participants' response-time and number of errors committed were recorded.

RESULTS

None of the scale items was removed. For the automatic condition, response-time items converged over one factor (αCronbach = 0.905) and number of errors converged over seven factors (αCronbach = 0.334). For the inhibition condition, response-time converged over one factor (αCronbach = 0.943) and number of errors converged over four factors (αCronbach = 0.728). Using electricity as a heating method inside the house was significantly associated with a lower response-time, whereas higher problematic mobile phone use was associated with higher response-time. Using wood as a heating system inside the house and higher problematic mobile phone use were associated with higher number of errors, while using Arabian incense (bakhour) inside the house was associated with lower number of errors.

CONCLUSION

We were able to set normative data for the HSCT Arabic version for use in the Lebanese population. Problematic mobile phone use was associated with lower inhibitory control in terms of response-time and errors number.

Interaction between physical activity and problematic mobile phone use on suicidality in Chinese college students

BACKGROUND

Previous research has found a relationship between problematic mobile phone use (PMPU) and suicidality. However, few studies have examined the interaction effects between low physical activity (PA) and PMPU on suicidality among college students. This study aimed to examine the interactions of PA and PMPU and their impact on suicidality in a school-based sample among Chinese college students.

METHODS

Analysis is based on date from two university in China, which recruited 4787 participants. Binomial logistic regression models were used to explore the associations of PA, PMPU with suicidal ideation and suicide attempt, as well as the interaction of PA and PMPU with suicidality.

RESULTS

The prevalence of suicide attempt and suicidal ideation were 3.5 and 7.2%, respectively. Low PA was significantly associated with suicide attempt (OR = 3.48, 95%CI: 2.52-4.81) and suicidal ideation (OR = 1.90, 95%CI: 1.46-2.46). PMPU was significantly associated with suicide attempt (OR = 3.65, 95%CI: 2.66-5.01) and suicidal ideation (OR = 2.83, 95%CI: 2.25-3.54). Interaction analysis indicated that low PA and PMPU were interactively associated with suicide attempt (OR = 9.51, 95%CI: 6.15-14.73, P < 0.001), RERI = 4.85(1.20-8.50), AP = 0.51(0.29-0.73), SI = 2.32(1.34-4.04). There was no additive interaction effects between PA and PMPU on suicidal ideation.

CONCLUSIONS

The findings reveals that the intervention programs of suicide attempt should consider the students PA levels and PMPU.

Are bored minds more likely to be addicted? The relationship between boredom proneness and problematic mobile phone use

BACKGROUND

Boredom proneness has been demonstrated as a salient vulnerability factor for problematic mobile phone use. However, the mediating and moderating mechanisms underlying this relationship are less investigated. In the current study, we constructed an integrative moderated mediation model to test the mediating role of depression and the moderating role of attentional control in the relationship between boredom proneness and problematic mobile phone use.

METHOD

A total of 1099 college students (M_age = 20.04; SD = 1.25) were recruited to fill out the questionnaires measuring boredom proneness, depression, problematic mobile phone use, and attentional control.

RESULTS

Depression partially mediated the relationship between boredom proneness and problematic mobile phone use. Attentional control moderated the indirect relationship between boredom proneness and problematic mobile phone use through depression, with the indirect relationship being weaker for college students with higher levels of attentional control. Moreover, attentional control moderated the direct relationship between boredom proneness and problematic mobile phone use, in that this relationship was stronger for college students with higher levels of attentional control.

CONCLUSIONS

These findings illuminate the pathway through which boredom proneness is linked to problematic mobile phone use (i.e., mediation) and the condition on which the relationship between boredom proneness and problematic mobile phone use depends (i.e., moderation). More importantly, this study revealed the potential "double-edged sword" effect of attentional control. These findings have implications for early intervention and prevention of problematic mobile phone use in college students.

Effect of the mobile phone-related background on inhibitory control of problematic mobile phone use: An event-related potentials study

The present study aims to provide electrophysiological evidence for deficient inhibitory control in problematic mobile phone use and to investigate whether reduced inhibition is more pronounced during exposure to a mobile phone related background cue. A screen scale of smartphone addiction was completed by 227 college students, and finally an experimental group and a control group consisting of 20 problematic mobile phone users and 19 controls were included in the study. Event-related potentials were recorded during a backgrounded Go/NoGo task performed by those two groups, in which either a frequent Go signal (letter "M") or a rare NoGo signal (letter "W") was superimposed on three different background cues: neutral, mobile phone application-related and mobile phone using-related pictures. Results showed that problematic mobile phone users performed more commission errors than controls following mobile phone application background. Furthermore, problematic mobile phone users displayed a weaker NoGo P3 amplitude than controls on the mobile phone application background. The result might suggest that there is no general impairment of inhibitory control in problematic mobile phone use. The deficient inhibitory control on behavioral and psychophysiological level appeared merely in the mobile phone-related background. Such deficient stimuli-specific inhibitory control appears at the late stage of inhibitory control. Prevention programs should be designed to curtail exposure to the mobile phone-related stimulus and enhance cognitive control of potential problematic mobile phone users.

Mobile phone use among car drivers and motorcycle riders: The effect of problematic mobile phone use, attitudes, beliefs and perceived risk

Mobile phone use while driving presents significant risks, potentially leading to injury or death through distracted driving. Using a case study of Vietnam, this research aimed to understand the effect of problematic mobile phone use (also known as mobile phone addiction or compulsive mobile phone use), attitudes and beliefs, and perceived risk on the frequency of mobile phone use among motorcyclists and car drivers. A self-administered questionnaire was distributed to motorcyclists (n₁= 529) and car drivers (n₂= 328) using an online survey and face-to-face survey. The survey took around 20-min to complete and participants were entered into a lottery for supermarket vouchers. Of the motorcyclists, 42% of the sample (the highest proportion) was in the 18-25 age group while the 36-45 age group accounted for the highest proportion among car drivers (34.8%). Using structural equation modelling (SEM), key findings showed that each construct influenced mobile phone use, but in different ways for motorcycle riders and car drivers. Attitudes and beliefs had the largest effect on mobile phone use while riding among motorcyclists, with problematic mobile phone use having the smallest influence. In contrast, problematic mobile phone use had the largest effect on mobile phone use while driving a car, with attitudes and beliefs having the smallest effect. The findings of this study point to the need for tailored interventions involving a range of actors (policymakers, police enforcement, mental health professionals, advocacy groups and the wider community) to raise awareness, modify attitudes and increase risk perception associated with mobile phone use while driving/riding. This can be achieved thorough educational tools and road safety campaigns which are focused on reducing this risky driving behaviour. This includes customising road safety programs for individuals and groups affected by problematic mobile phone use such as targeted advertising.

Impact of problematic mobile phone use and insufficient physical activity on depression symptoms: a college-based follow-up study

Background

Insufficient physical activity (IPA) and mobile phone dependence are common coexisting behaviors among college students. However, the impact of the synergies between the two behaviors on depression has yet to be validated. Therefore, this study evaluated independent and interactive associations of problematic mobile phone use (PMPU) and IPA with depression symptoms and increased depressive symptoms among Chinese college students.

Methods

In total, 2134 college students participated in this follow-up study, which was conducted between June 2014 (wave 1) and December 2014 (wave 2) at Anhui Medical University. The Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use and the Center for Epidemiologic Studies Depression Scale were used to assess PMPU and depression symptoms, respectively. Physical activity (PA) was assessed with a reliable question from the Youth Risk Behavior Survey. Joint effects of PMPU and PA were calculated, and increased depressive symptoms were assessed. We used multivariable-adjusted odds ratios (OR) with 95% confidence intervals (CI) to evaluate associations between depression symptoms and PMPU, IPA, and the PMPU/IPA joint effect, estimated by binary logistic regression models.

Results

PMPU and high PMPU/IPA joint effect scores were significantly associated with depression symptoms in waves 1 (OR 7.36, 95% CI: 5.09, 10.66) and 2 (OR 3.74, 95% CI: 2.56, 5.48). IPA was significantly associated with depression symptoms in wave 1 (OR 1.40, 95% CI: 1.09, 1.79) but not wave 2 (OR 1.24, 95% CI: 0.95, 1.62). PMPU and high PMPU/IPA joint effect scores were also significantly associated with increased depressive symptoms (OR 2.36, 95% CI: 1.55, 3.60).

Conclusions

These results suggest that PMPU is an important factor for depression in college students, and IPA may be a synergistic factor.

Investigation of Problematic Mobile Phones Use and Fear of Missing Out (FoMO) Level in Adolescents

The aim of the study is to define problematic mobile phone use (PMPU) and level of fear of missing out developments in social media (FoMO) in adolescents. The study sample consisted of 1630 students. The data were collected using fear of missing out scale (FoMOS), and scale for problematic mobile phone use (PU). Statistically significant differences were found the mean scores on PU according to gender, age, and academic success. The students' mean scores on PU and FoMOS were found to significant difference depending on frequency of social media and phone use. A significant relationship was found between the mean scores for FoMOS and PU. The regression analyses showed that the independent variables predict 27.5% of PMPU.

Problematic Mobile Phone Use and Addiction Across Generations: the Roles of Psychopathological Symptoms and Smartphone Use

Contemporary technological advances have led to a significant increase in using mobile technologies. Recent research has pointed to potential problems as a consequence of mobile overuse, including addiction, financial problems, dangerous use (i.e. whilst driving) and prohibited use (i.e. use in forbidden areas). The aim of this study is to extend previous findings regarding the predictive power of psychopathological symptoms (depression, anxiety and stress), mobile phone use (i.e. calls, SMS, time spent on the phone, as well as the engagement in specific smartphone activities) across Generations X and Y on problematic mobile phone use in a sample of 273 adults. Findings revealed prohibited use and dependence were predicted by calls/day, time on the phone and using social media. Only for dependent mobile phone use (rather than prohibited), stress appeared as significant. Using social media and anxiety significantly predicted belonging to Generation Y, with calls per day predicted belonging to Generation X. This finding suggests Generation Y are more likely to use asynchronous social media-based communication, whereas Generation X engage more in synchronous communication. The findings have implications for prevention and awareness-raising efforts of possibly problematic mobile phone use for educators, parents and individuals, particularly including dependence and prohibited use.

Short version of the Smartphone Addiction Scale adapted to Spanish and French: Towards a cross-cultural research in problematic mobile phone use

Research into smartphone addiction has followed the scientific literature on problematic mobile phone use developed during the last decade, with valid screening scales being developed to identify maladaptive behaviour associated with this technology, usually in adolescent populations. This study adapts the short version of the Smartphone Addiction Scale [SAS-SV] into Spanish and into French. The aim of the study was to (i) examine the scale's psychometric properties in both languages, (ii) estimate the prevalence of potential excessive smartphone use among Spanish and Belgian adults, and (iii) compare the addictive symptomatology measured by the SAS-SV between potentially excessive users from both countries. Data were collected via online surveys administered to 281 and 144 voluntary participants from both countries respectively, aged over 18years and recruited from academic environments. Results indicated that the reliability was excellent (i.e., Cronbach alphas: Spain: .88 and Belgium: .90), and the validity was very good (e.g., unifactoriality with a 49% and 54% of variance explained through explorative factor analysis, respectively). Findings showed that the prevalence of potential excessive smartphone use 12.5% for Spanish and 21.5% for francophone Belgians. The scale showed that at least 60% of excessive users endorsed withdrawal and tolerance symptoms in both countries, although the proposed addictive symptomatology did not cover the entire group of estimated excessive users and cultural differences appeared. This first cross-cultural study discusses the smartphone excessive use construct from its addictive pathway.

Prevalence and co-occurrence of compulsive buying, problematic Internet and mobile phone use in college students in Yantai, China: relevance of self-traits

BACKGROUND

Until now, most research in the prevalence of compulsive buying (CB) has been developed from samples in western developed countries, this study aimed to estimate the prevalence and co-morbidities of CB, problematic Internet use (PIU) and problematic mobile phone use (PMPU) in college students in Yantai, China. Moreover, based on the lack of research focusing on differences between CB and addiction, we will explore whether CB and PIU/PMPU individuals are characterized by the same self-traits (i. e., self-control, self-esteem and self-efficacy) related profile.

METHODS

A total of 601 college students were involved in this cross-sectional study. Compulsive buying, problematic Internet and mobile phone use and self-traits were assessed by self-reported questionnaires. The demographic information and use characteristics were included in the questionnaires.

RESULTS

The incidence of CB, PIU and PMPU were 5.99, 27.8 and 8.99% respectively. In addition, compared with rural students, students from cities are more likely to get involved in CB. Students using mobile phone to surf the Internet displayed higher risk of PIU than counterparts using computer. Students using Internet or mobile phone longer are more prone to problematic use. Furthermore, we found the strong correlations and high co-morbidities of CB, PIU and PMPU and self-control was the most significant predictor for all three disorders. However, self-esteem and self-efficacy were significant predictors only for CB.

CONCLUSIONS

Our findings indicated that with the prevalence of CB and PMPU roughly equivalent to that demonstrated in previous studies, PIU in Chinese college students is serious and deserves more attention. Furthermore, besides the impulsive aspect common with addiction, CB is also driven by painful self-awareness derived from low self-regard which implies the obsessive-compulsive aspect.

Self-control and problematic mobile phone use in Chinese college students: the mediating role of mobile phone use patterns

BACKGROUND

With the popularity of mobile phones, problematic mobile phone use is getting increasing attention in recent years. Although self-control was found to be a critical predictor of problematic mobile phone use, no study has ever explored the association between self-control and mobile phone use patterns as well as the possible pathway how self-control affects problematic mobile phone use.

METHODS

Four hundred sixty-eight college students were randomly selected in this study. Data were collected using the Problematic Mobile Phone Use Scale, the Self-Control Scale, and the Mobile Phone Use Pattern Questionnaire. Statistical tests were conducted to identify the potential role of mobile phone use patterns in the association between self-control and problematic mobile phone use.

RESULTS

In this sample, female students displayed significant higher mobile phone dependence than males. Self-control was negatively correlated with interpersonal, transaction and entertainment mobile phone use patterns, but positively correlated with information seeking use pattern. Self-control could predict problematic mobile phone use directly and indirectly via interpersonal and transaction patterns.

CONCLUSIONS

Our research provided additional evidence for the negative association between self-control and problematic mobile phone use. Moreover, interpersonal and transaction use patterns played a mediating role in this link.

Problematic mobile phone use of Swiss adolescents: is it linked with mental health or behaviour?

OBJECTIVES

To investigate the associations between problematic mobile phone use and mental health and behavioural problems in 412 Swiss adolescents owning a mobile phone while controlling for amount of mobile phone use.

METHODS

Problematic mobile phone use was determined by the MPPUS-10 (Mobile Phone Problem Use Scale) and related to health and behavioural problems by means of multivariable regression modelling.

RESULTS

MPPUS-10 was 4.7 (95 % CI 1.8, 7.6) units higher in girls than in boys, increased significantly with age and was significantly decreased with increasing educational level of the parents. Furthermore, problematic mobile phone use was associated with impaired psychological well-being, impaired parent and school relationships and more behavioural problems but was not related to peer support and social acceptance.

CONCLUSIONS

Our study indicates that problematic mobile phone use is associated with external factors such as worse home and school environment and internal factors such as impaired mental health and behavioural problems of the adolescents and thus problematic mobile phone use should be addressed, in particular when dealing with adolescents showing behavioural or emotional problems.
