A ‘components’ model of addiction within a biopsychosocial framework

Differences between problematic internet and smartphone use and their psychological risk factors in boys and girls: a network analysis

BACKGROUND

Problematic internet and smartphone use are significant health challenges for contemporary adolescents. However, their mutual relationship is unclear because studies investigating these phenomena are scarce. The present study aimed to investigate the psychological risks and protective factors associated with problematic internet and smartphone use.

METHOD

A representative sample of Slovak adolescents (N = 4070, M_age = 14.38, SD_age = 0.77, 50.5% girls) from the Health Behavior in School-aged Children project was analyzed using network analysis separately for boys and girls.

RESULTS

The results showed weak (for boys) and moderate (for girls) associations between problematic internet use and problematic smartphone use. Risk factors showed stronger associations with problematic internet use than problematic smartphone use, with the exception of fear of missing out, which was strongly associated with problematic smartphone use. The central nodes were externalizing problems for boys and internalizing problems, externalizing problems, and resilience for girls.

CONCLUSION

The study concluded that while problematic internet use and problematic smartphone use are somewhat related, they differ at the psychological level. In addition, the phenomena are rather different between boys and girls.

Discussing evidence on the components model of addiction. A commentary on Fournier et al. (2023)

Fournier and colleagues have recently examined whether the components model of addiction includes peripheral features of addiction not indicative of a disorder. The authors conducted factor analyses and network analyses of responses (N = 4,256) to the Bergen Social Media Addiction Scale. Their results showed that a bidimensional solution best fitted the data and that two items examining salience and tolerance loaded on a factor not associated with symptoms of psychopathology signifying salience and tolerance as peripherical features of addiction to social media. A reanalysis of the data (focused on the internal structure of the scale) was believed necessary considering that previous studies consistently demonstrated the one-factor solution of the scale and that four independent samples were analysed as a single sample potentially limiting the results of the original study. Findings of the reanalyses of Fournier and colleagues' data provided additional support for a one-factor solution of the scale. Potential explanations of the findings and suggestions for future research were elaborated.

Relationships between Depression, Fear of Missing Out and Social Media Addiction: The Mediating Role of Self-Esteem

The present study examines the relationships between depression, self-esteem, fear of missing out, online fear of missing out, and social media addiction in a sample of 311 Italian young adults (66.2% women and 33.8% men), ages 18-35 yrs. (M = 23.5; SD = 3.5). The following hypotheses were tested: that depression is positively correlated with fear of missing out, online fear of missing out, and social media addiction, while being significantly negatively correlated with self-esteem; that depression, self-esteem, fear of missing out, and online fear of missing out explain social media addiction scores; that self-esteem mediates the relationship between depression and social media addiction; and that, among Italian participants between the ages of 18 and 35, younger women report higher scores on fear of missing out, online fear of missing out, and social media addiction. Results strongly supported the hypotheses. Taken together, our findings not only contribute to the growing body of research on online addictive behaviors and individuals' well-being, but also provide support for prevention programs in the field.

Profiles of Pornography Use Based on Addictive Mechanisms and Psychopathological Features

Studies using person-centered approaches to further explore the profiles of pornography users throw their psychiatric features are lacking. This study was designed to examine the different profiles of pornography users based on the addictive dimensions of Problematic Pornography Use (PPU) and to characterize these profiles according to psychopathological variables such as depression, anxiety, attention deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). A sample of 1001 French adults participated to a survey containing scales related to psychopathological variables, cybersexual addiction and PPU. PPU was assessed with the French Version of Problematic Pornography Consumption Scale (Fr-PPCS-18). An Agglomerative Hierarchical Classification was performed on the basis of FR-PPCS-18. A student's t-test was used to observe PPU and psychopathological differences between profiles. Findings revealed three profiles of users: non-problematic users (66.5%), at-risk users (29.9%), and problematic users (3.6%). There were significant differences between the three profiles concerning levels of global PPU, PPU mechanisms, cybersexual addiction symptoms, ADHD symptomatology and depressive symptomatology. Results confirmed the existence of different levels of severity of pornography use corresponding to three different profiles. Also, findings revealed the influence of ADHD symptoms, obsessive-compulsive symptoms and depressive symptoms on PPU.

Stigmatizing attitudes toward Internet gaming disorder, Problematic smartphone use and Problematic social networking site use: An experimental vignette study

Public stigma on substance and gambling disorders have been well documented. Negative effects of stigma include shame, embarrassment, fear being judged and the determent of help-seeking behaviors among stigmatized individuals. Less is known about the public perception toward Internet gaming disorder (IGD) and other widespread problematic behaviors that share some characteristics with established behavioral addictions, such as Problematic smartphone use (PSU) and Problematic social networking sites use (PSNSU). The purpose of this study is to compare the public perception of problematic Internet gamers, problematic smartphone users and problematic social networking sites users using an experimental within-group vignette study design. A sample of 280 adults (F = 72.1%; M_age = 32.84, SD = 13.85) was recruited and completed the study online. Participants were presented with male OR female vignettes (i.e. the gender of the target in the vignette was randomized) describing an individual with IGD, PSU, and PSNSU. A repeated-measures ANOVA followed by post hoc tests using Bonferroni's correction was used. IGD was seen as more serious, more noticeable, and less understandable than both PSU and PSNU. Moreover, participants' emotional reaction (e.g., anger and sadness) and desired social distance were significantly stronger toward IGD. However, vanity attributions were higher for individuals with PSNSU, which were also more blamed compared to both IGD and PSU. PSU was seen as more controllable than both IGD and PSNSU. The results, taken together, suggest that IGD is perceived as more inherently problematic, but PSNSU also seem to deserve scientific attention as individuals showing symptoms of PSNSU are blamed more than problematic Internet gamers. Our findings provide initial information that can be used when developing interventions to impact stigma toward technological addictions.

Severity of behavioral addiction symptoms among young adults using non-prescribed sedatives/hypnotics

Introduction

Young adulthood is considered a critical period in terms of non-medical use of sedatives/hypnotics (NMUSH) as well as different types of behavioral addictions (BAs). However, the relationship between these behaviors has received scarce attention among young adult samples. Therefore, the aim of the present study was to investigate the association between NMUSH and symptoms of distinct BAs among young adults.

Materials and methods

Analyses were conducted based on the data of two large sample studies (including a representative sample) carried out with young adult samples. The following BAs were assessed: problematic internet use, problematic video gaming, problematic social media use, problem gambling, exercise addiction, eating disorders, compulsive buying behavior, problematic mobile phone use, work addiction, and hair pulling. Symptoms of distinct BAs were analyzed in three groups formed based on the NMUSH: non-users, lifetime users, and current users.

Results

The symptoms of problematic internet use, problematic social media use, problem gambling, exercise addiction, eating disorders, compulsive buying behavior and work addiction were significantly more severe among lifetime and/or current non-medical sedative and hypnotic users, compared to the non-user participants. The symptoms of problematic mobile phone use were the most severe in the non-user group.

Conclusions

The results suggest co-occurrence between NMUSH and distinct BAs among young adults. These findings draw attention to the need for preventive interventions for this high-risk population.

Psychometric properties of the Bergen Social Media Addiction Scale: An analysis using item response theory

Background

Social media use has become an everyday behavior in contemporary life resulting in increased participation. A minority of individuals, especially younger adults, may engage excessively with the medium, resulting in the emergence of problematic social media use (PSMU). One way of assessing PSMU is by administering the Bergen Social Media Addiction Scale (BSMAS). The present study investigated the psychometric properties and prevalence of the BSMAS using Item Response Theory (IRT). Additionally, it evaluated risk factors such as gender and age.

Methods

A relatively large community sample (N = 968, Mage  = 29.5 years, SD = 9.36, 32.5% women) completed the BSMAS online.

Results

IRT analyses showed differences regarding the BSMAS items' discrimination, difficulty, and reliability capacities, with a raw score exceeding 26 (out of 30) indicating a higher risk of PSMU (n = 11; 1.1%). Females and younger participants were at greater risk of developing PSMU.

Conclusion

The BSMAS functions as a reliable measure of PSMU, particularly between average to high levels of the trait. Additionally, younger participants were shown to be at higher risk of PSMU suggesting that prevention and intervention protocols should focus on this group.

The associations between attachment, self-esteem, fear of missing out, daily time expenditure, and problematic social media use: A path analysis model

The present study investigated the factors that may be associated with a dysfunctional use of social media use, by exploring the association between adult attachment patterns and problematic social media use and analyzing the sequential mediation of self-esteem, fear of missing out (FoMO), and time spent on social media. A sample of 470 social media users (M_age = 33.76 years; SD = 14.267; 70 % women) completed the Bergen Social Media Addiction Scale, Fear of Missing Out Scale, Rosenberg Self-Esteem Scale, and Relationship Questionnaire. Results showed a path analysis model providing an excellent fit to the data (χ² = 2.939, p = 0.230; GFI = 0.998, TLI = 0.987, CFI = 0.998, RMSEA = 0.032, SRMR = 0.016). A significant and positive total effect in the associations between preoccupied and fearful attachment patterns and problematic social media use emerged. Both preoccupied and fearful attachment patterns were also related to self-esteem, FoMO, and time spent on social media, which were sequentially associated and were, in turn, significantly related to problematic social media use. Finally, when self-esteem, FoMO, and time spent on social media were added into the model, they totally mediated the relationships between preoccupied and fearful attachment patterns and problematic social media use, suggesting a full multiple mediation model (R² = 0.33). Such data may provide useful information for clinical practice to develop tailored interventions and prevention programs to address the compensatory and problematic use of social media.

Stress and Internet Addiction: Mediated by Anxiety and Moderated by Self-Control

Background

The link between stress and Internet addiction (IA) has been confirmed. However, the mechanism underlying the correlation is poorly understood. Thus, the current study proposed a moderated mediation model to test the mediating role of anxiety and the moderating role of self-control (SC) in the link between stress and IA.

Methods

Eight hundred and sixty-one Chinese college students (M_age = 20.62 years; SD = 1.58; male = 47.7%) were required to complete an online questionnaire package, including a depression-anxiety-stress scale, a self-control scale, and an Internet addiction test. The PROCESS macro developed based on SPSS was used to test the moderated mediation model.

Results

When controlling for gender and age, the results revealed that anxiety partially mediated the link between stress and IA. Specifically, the more stressed college students are, the higher their anxiety level is, and the more likely they are to become addicted to the Internet. Additionally, the direct and indirect links between stress and IA were all moderated by SC. SC buffered the effect of stress on anxiety and anxiety on IA but enhanced stress on IA.

Conclusion

These findings emphasized the predictor role of stress on IA and provided insights on intervening in college students' excessive Internet use behaviors for educators, such as reducing anxiety levels and improving self-control abilities.

Effect of Social Media Addiction on Executive Functioning Among Young Adults: The Mediating Roles of Emotional Disturbance and Sleep Quality

Introduction

The increased research examining social media addiction with its negative consequences has raised concerns over the past decade. However, little research has investigated the association between social media addiction and executive functioning as well as the mechanisms underlying this relationship.

Methods

Using a survey, the present study examined the association between social media addiction and executive functioning via emotional disturbance and sleep quality among 1051 Chinese young adults, aged 18 to 27 years old (M=21.02 years [SD=1.89]; 34.41% male).

Results

The results showed that social media addiction had a significant negative association with executive functioning but positive associations with emotional disturbance and poor sleep quality. Structural equation modeling suggested that there was a significant direct effect between social media addiction and executive functioning. Indirect effects via two paths (ie, emotional disturbance alone, and both emotional disturbance and sleep quality) were also statistically significant.

Discussion

The findings indicate that both emotional disturbance and poor sleep quality are risk-enhancing mediators in the relationship between social media addiction and executive functioning. Intervention programs (eg, emotional regulation strategies) should be considered to reduce the adverse effects of social media addiction on cognitive impairment among young adults.

A serial mediation model of social media addiction and college students' academic engagement: the role of sleep quality and fatigue

BACKGROUND

It has been documented that social media addiction (SMA) has a detrimental effect on college students' academic engagement. However, the mechanisms underlying this association are not well understood. This study aimed to determine the serial mediation effects of sleep quality and fatigue on the relationship between SMA and academic engagement among college students.

METHODS

A cross-sectional survey was conducted with 2661 college students (43.3% males, mean age = 19.97 years). The participants completed the Bergen Social Media Addiction Scale, the Utrecht Student Work Engagement Scale for Students, the Pittsburgh Sleep Quality Index, and the Fatigue Assessment Scale. The serial mediation effects were examined using Model 6 in the Hayes' PROCESS macro for SPSS.

RESULTS

The results showed that SMA among college students had a direct negative relationship with their academic engagement (Effect = - 0.051, 95% CI: -0.087 to - 0.015). In addition, sleep quality and fatigue mediated the relationship between SMA and academic engagement both independent and serially, with the independent mediation effect of sleep quality being - 0.031 (95% CI: -0.048 to - 0.016), the independent mediation effect of fatigue being - 0.109 (95% CI: -0.133 to - 0.088), and the serial mediation effect of sleep quality and fatigue being - 0.080 (95% CI: -0.095 to - 0.066). The total indirect effect of the three mediation paths was 80.9%.

CONCLUSIONS

Decreased academic engagement caused by SMA can be aggravated by poor sleep quality and fatigue. Strengthening supervision and intervention in social media use among college students, supplemented by attention to psychosomatic health, including sleep quality and fatigue could promote their engagement in academic work.

Prevalence and Determinants of Social Media Addiction among Medical Students in a Selected University in Saudi Arabia: A Cross-Sectional Study

Social media addiction has become a serious public health concern due to its adverse psychological effects. Therefore, the purpose of this study was to assess the prevalence and determinants of social media addiction among medical students in Saudi Arabia. A cross-sectional study was designed. Participants (n = 326) from King Khalid University in Saudi Arabia completed the sociodemographic information, patient health questionnaire-9 scale, and the generalized anxiety disorder-7 tool to measure explanatory variables. The Bergen social media addiction scale (BSMAS) was used to measure social media addiction. A multiple linear regression model was fitted to investigate the predictors of social media addiction. The prevalence of social media addiction among study participants was 55.2% (mean BSMAS score: 16.6). According to the adjusted linear regression, male students had higher social media addiction scores than their female counterparts (β = 4.52, p < 0.001). Students' academic performance was negatively associated with social media addiction scores. Moreover, students with symptoms of depression (β = 1.85, p = 0.005) or anxiety (β = 2.79, p = 0.003) had a higher BSMAS score compared to their counterparts. Further longitudinal studies are warranted to identify the causal factors of social media addiction, which would assist intervention initiatives by policymakers.

Six addiction components of problematic social media use in relation to depression, anxiety, and stress symptoms: a latent profile analysis and network analysis

BACKGROUNDS

Components of addiction (salience, tolerance, mood modification, relapse, withdrawal, and conflict) is the most cited theoretical framework for problematic social media use (PSMU). However, studies criticized its ability to distinguish problematic users from engaged users. We aimed to assess the association of the six criteria with depression, anxiety, and stress at a symptom level.

METHODS

Ten thousand six hundred sixty-eight participants were recruited. Bergen Social Media Addiction Scale (BSMAS) was used to detect six addiction components in PSMU. We applied the depression-anxiety-stress scale to assess mental distress. Latent profile analysis (LPA) was conducted based on BSMAS items. Network analysis (NA) was performed to determine the symptom-symptom interaction of PSMU and mental distress.

RESULTS

(1) Social media users were divided into five subgroups including occasional users (10.6%, n = 1127), regular users (31.0%, n = 3309), high engagement low risk users (10.4%, n = 1115), at-risk users (38.1%, n = 4070), and problematic users (9.8%, n = 1047); (2) PSMU and mental distress varied markedly across subgroups. Problematic users had the most severe PSMU, depression, anxiety, and stress symptoms. High engagement users scored high on tolerance and salience criteria of PSMU but displayed little mental distress; (3) NA showed conflict and mood modification was the bridge symptoms across the network, while salience and tolerance exhibited weak association with mental distress.

CONCLUSIONS

Salience and tolerance might not distinguish engaged users from problematic users. New frameworks and assessment tools focusing on the negative consequences of social media usage are needed.

Exploring the indirect effect of loneliness in the association between problematic use of social networks and cognitive function in Lebanese adolescents

BACKGROUND

Problematic use of social networks is a widespread problem that may exert deleterious impacts on cognitive functions. Moreover, studies have added an important link between loneliness and its harmful effect on cognitive functions. Other studies have also revealed that problematic use of social networks among teenagers has a pejorative influence on their social interactions, leading to increased social isolation. Therefore, the goal of our research was to investigate the link between problematic use of social networks and cognitive function in a group of Lebanese adolescents while also taking into consideration the indirect role of loneliness in this relationship.

METHODS

This cross-sectional study, which was carried out between January and April 2022, included 379 teenagers (aged between 13 and 17 years), from all Lebanese governorates. The PROCESS SPSS Macro version 3.4, model four was used to compute three pathways. Pathway A determined the regression coefficient for the effect of problematic use of social networks on loneliness; Pathway B examined the association between loneliness and cognitive function, and Pathway C' estimated the direct effect of problematic use of social networks on cognitive function.

RESULTS

Higher negative social comparison, addictive consequences of problematic use of social networks, and loneliness were significantly associated with worse cognitive function. Loneliness mediated the association between negative social comparison and worse cognitive function, as well as between addictive consequences of problematic use of social networks and worse cognitive function. In addition, higher financial burden was significantly correlated with worse cognitive function, whereas higher physical activity was related to better cognitive function.

CONCLUSION

In sum, the current study supports that problematic use of social networks is negatively associated with adolescents' cognitive function, where loneliness seems to play a pivotal role in this equation. The results thus endorse the importance of helping Lebanese adolescents to overcome problematic use of social networks and recover from their loneliness, to achieve a better cognitive/academic performance.

Gaming among female adolescents: profiling and psychopathological characteristics in the Indian context

Objectives

Gaming is a predominant leisure time activity among adolescents, and the literature suggests that unrestrained gaming behavior might lead to gaming disorder. ICD-11 and DSM-5 have recognized gaming disorder as a psychiatric condition and grouped it under the behavioral addiction category. Research on gaming behavior and addiction is largely based on data from the male population, and problematic gaming has largely been understood from the male perspective. In this study, we are attempting to bridge the existing lacuna in the literature by exploring gaming behavior, gaming disorder, and its related psychopathological characteristics among female adolescents in India.

Methods

The study was conducted on a sample of 707 female adolescent participants who were contacted through schools and academic institutes in a city in Southern India. The study adopted a cross-sectional survey design, and data were administered using the mixed modality of online and offline data collection. The participants filled out the following set of questionnaires: socio-demographic sheet, Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), Strength and Difficulties Questionnaire (SDQ), Rosenberg self-esteem scale, and Brief sensation-seeking scale (BSSS-8). The data gathered from the participants were then statistically analyzed using SPSS software version 26.

Results

The descriptive statistics revealed that 0.8% of the sample (i.e., five participants out of 707) obtained scores meeting gaming addiction criteria. Correlation analysis demonstrated a significant relationship between all the psychological variables with total IGD scale scores (p < 0.05). Total SDQ, total BSSS-8, and domain scores of SDQ, such as emotional symptoms, conduct, hyperactivity, and peer problems, were positively correlated, whereas total Rosenberg scores and domain scores of prosocial behaviors of SDQ were negatively correlated. The Mann-Whitney U-test was employed to compare "with gaming disorder" and "without gaming disorder" categories of female participants. Comparing these two groups revealed significant differences in emotional symptoms, conduct, hyperactivity/inattention, peer problem, and self-esteem scale scores. Furthermore, quantile regression was computed, showing that conduct, peer problem, and self-esteem displayed trend-level prediction for gaming disorder.

Conclusion

Female adolescents prone to gaming addiction can be identified through psychopathological characteristics of conduct, peer problem, and low self-esteem. This understanding can be useful in developing a theoretical model focusing on early screening and preventive strategies for at-risk female adolescents.

Are Cyberchondria and Intolerance of Uncertainty Related to Smartphone Addiction?

Smartphones are a medium for performing online activities, and one such activity could be the compulsive online health information search - cyberchondria. This study aimed to test whether cyberchondria and intolerance of uncertainty (IU) positively predict smartphone addiction (SA), adjusted for age, gender, daily use duration, the reason for using smartphones, and symptoms of anxiety and depression. The sample consisted of 471 adults (55.2% women) from the general population without chronic diseases (Mage = 38.67). Regression analysis showed that IU was a positive predictor of SA (β = .17, p < .001), as well as cyberchondria (β = .14, p < .001), which had a unique contribution to the explanation of SA, relative to IU. Other significant predictors were average daily smartphone use and entertainment use, the latter being the strongest predictor in the model. These results revealed cyberchondria as a unique predictor of SA.

Effects of a 7-Day Pornography Abstinence Period on Withdrawal-Related Symptoms in Regular Pornography Users: A Randomized Controlled Study

Little is known about whether withdrawal-like symptoms manifest when regular pornography users attempt to abstain from pornography. The present study used a randomized controlled design to examine whether (1) negative abstinence effects that may be potentially reflective of withdrawal-related symptoms manifest when a non-clinical sample of regular pornography users attempt to abstain from pornography for a 7-day period and (2) these negative abstinence effects would only manifest (or manifest more strongly) for those with higher levels of problematic pornography use (PPU). A total of 176 undergraduate students (64.2% female) who were regular pornography users (defined as having used pornography ≥ three times a week in the past 4 weeks) were randomly assigned to an abstinence group (instructed to attempt abstinence from pornography for 7 days, n = 86) or a control group (free to watch pornography as usual, n = 90). Participants completed measures of craving, positive and negative affect, and withdrawal symptoms at baseline and each night of the 7-day period. Contrary to the confirmatory hypotheses, there were no significant main effects of group (abstinence vs. control) or group × PPU interaction effects on any of the outcome measures, controlling for baseline scores. These findings indicate that no evidence of withdrawal-related symptoms was found for abstaining participants, and this was not dependent on level of PPU. However, exploratory analyses showed a significant three-way interaction (group × PPU × past 4-week frequency of pornography use [FPU]) on craving, where an abstinence effect on craving was found at high levels of PPU only once past 4-week FPU reached the threshold of daily use. While these exploratory findings should be interpreted with caution, they suggest that abstinence effects could potentially manifest when there is a combination of high PPU and high FPU-a hypothesis that warrants investigation in future prospective abstinence studies.

Behavioral Addictive Disorders in Children and Adolescents

Behavioral addictive disorders (BADs) are syndromes similar to substance use disorders (SUDs) but with a focus on behaviors rather than on use of psychoactive substances. These non-substance-related disorders occur when typical, rewarding behaviors, such as gambling, playing video games, and using social media, are done in excess, affecting daily functioning and/or inducing severe psychological distress. BADs are chronic and relapsing, and characterized by a failure to resist an impulse, drive, or temptation to perform an act despite adverse consequences. They are common among youth and linked to poor mental health outcomes and negative social consequences. Given the high prevalence of BADs and their potential serious outcomes, the burden on the youth population's mental health can be consequential.1.

Love Addiction - Current Diagnostic and Therapeutic Paradigms in Clinical Psychology. (v2)

Background

We have investigated and analyzed the latest research on love addiction in the fields of clinical psychology, diagnosis, psychotherapy and treatment.

Methods

From 30 November 2021 to July 2022 a review was conducted aimed at identifying the current diagnostic paradigms associated with this new behavioral dependence, investigating in depth what has not yet emerged, searching for strong and weak correlations with related theoretical constructs, comorbidities, investigate which evaluation scales are currently used and outline a guiding design that allows you to move between current scientific discoveries, searching for relevant studies in the databases PubMed, National Center for Biotechnology Information (NCBI), PsycINFO, MDPI, APA, ScienceDirect, and ReserchGate.

Results

We identified a total of 102 unique articles. Among these, 22 full-text articles were assessed for eligibility and 5 of these met the eligibility criteria and were, therefore, included in the final systematic review.

Conclusions

Group psychotherapy has proved to be a valid alternative, in fact the scientific landscape suggests that most group therapies are successful because these dynamics involve the reward and attachment systems in the brain in most subjects. Although there is currently no official classification for this type of addiction, the continuing interests of clinical psychology open up new scenarios for achieving greater psychophysical well-being.

Dating App Use and Wellbeing: An Application-Based Pilot Study Employing Ecological Momentary Assessment and Objective Measures of Use

Smartphones are part of individuals' daily lifestyles, as are smartphone applications such as dating apps. Previous evidence suggests that high engagement in dating applications can be detrimental to some users' wellbeing. However, much of the published research has relied on cross-sectional studies and self-report measures. Therefore, the present study aims to overcome the limitations of subjective measures in cross-sectional designs by investigating for the first time the relationship between dating app users' wellbeing (self-esteem, craving and mood) and objective measures of their use during a one-week period. To do this, the present study employed a newly developed application, DiaryMood and utilized ecological momentary assessment (EMA), as it measured subjects' mood, self-esteem and craving three times per day and the time spent using the dating apps per day during one week. A convenience sample of 22 online dating app users participated in the present study. Findings from a three-level multilevel analysis indicated that increased time spent on dating apps predicted craving among dating app users and that notifications led to an improved mood and higher self-esteem. The results are discussed in relation to previous online dating studies. In sum, the present study sets a precedent for the use of EMA within the scope of online dating research, which may promote further studies adopting this methodology.

The relationship between self-esteem and mobile phone addiction among college students: The chain mediating effects of social avoidance and peer relationships

Introduction

Mobile phone addiction has a negative impact on the physical and mental health of college students, which has attracted extensive attention from scholars.

Methods

In this study, we investigated the mechanism of the influence of self-esteem on mobile phone addiction among 694 college students using the Self-Esteem Scale, the Mobile Phone. Addiction Scale, the Peer Relationship Scale and the Social Avoidance and Distress Scale.

Results

The results showed that (1) self-esteem significantly and negatively predicted mobile phone addiction; (2) self-esteem influenced mobile phone addiction through the mediating effect of social avoidance; (3) self-esteem influenced mobile phone addiction through the mediating effect of peer relationships; and (4) social avoidance and peer relationships played a chain mediating role in the influence of self-esteem on mobile phone addiction.

Discussion

These findings can help researchers and educators better understand the underlying mechanisms of the relationship between self-esteem and mobile phone addiction and to provide practical and effective operational suggestions for the prevention and intervention of mobile phone addiction among college students.

Using Theoretical Models of Problematic Internet Use to Inform Psychological Formulation: A Systematic Scoping Review

BACKGROUND

Empirical research has been produced on the topic of 'Internet Addiction' or 'Problematic Internet Use' (PIU) for more than 20 years, with a variety of theoretical approaches suggested by scholars to account for the behaviour. However, the discourse has been fraught with debate around construct definition, measurement, and validity.

AIMS

This review aimed to systematically review the extant literature on the topic of PIU, to identify the published psychological theories in the area, and to synthesise the findings to produce actionable information for practicing psychologists as well as academics.

METHOD

Given the breadth of the aims, a scoping review methodology was utilised. Four major reference libraries (Scopus, Proquest, Pubmed, Technology Research Database) were searched using a string of relevant terms.

RESULTS

Of 1412 initial search results, eighteen theories were included in the study. Nine theories related to generalised PIU, seven related to specific Internet use issues, such as online gaming or social media, while two theories took account of both a generalised and specific view. Data were analysed using Formulation-Based Thematic Analysis (FBTA) to synthesise theory elements under the deductive headings of Predisposing, Precipitating, Maintaining, and Protective factors.

DISCUSSION

The lack of protective factors against PIU was a prominent finding. The utility of the psychological formulation approach, particularly in an area fraught with conceptual debate and frustration with traditional medical classification systems, is emphasised.

The association between problematic pornography use and eating disorder symptoms among heterosexual and sexual minority men

In this study, we investigated the link between problematic pornography use and eating disorder symptoms in men, with body comparison and body image as mediators, and perceived realism and anxiety and depression as moderators. We also analyzed the model for both heterosexual and sexual minority men to detect any differences. The current study included 705 Israeli men, 479 of whom identified as heterosexual and 226 as sexual minority. The majority of the sample (90.6%) identified as Jewish with a mean age of 32.5. Results showed that problematic pornography use was linked to more upward body comparison, which in turn was related to negative body image, and ultimately, increased severity of eating disorder symptoms. Anxiety and depression moderated the association between male body image and eating disorder symptoms. However, perceived realism did not moderate the link between problematic pornography use and upward body comparison. Whereas there were significant differences in the mean rank values between heterosexual and sexual minority men in all measures, the processes linking these measures were virtually the same. To reduce the risk of developing or worsening eating disorder symptoms, clinicians working with male clients should assess for problematic pornography use and body image concerns during therapy.

A rise in social media use in adolescents during the COVID-19 pandemic: the French validation of the Bergen Social Media Addiction Scale in a Canadian cohort

INTRODUCTION

Social media use has grown dramatically since its inception in the early 2000s and has further increased during the COVID-19 pandemic. Problematic use of social media (PUSM) is a type of behavioural addiction which has generated increasing interest among mental health clinicians and scholars in the last decade. PUSM is associated with multiple psychiatric conditions and is known to interfere with patients' daily functioning. There is no single accepted definition of PUSM, nor means of measuring it, in the literature. The Bergen Social Media Addiction Scale (BSMAS) is a helpful tool for identifying PUSM. This paper aims to validate BSMAS and to translate it from English into French, with the goal of making this clinical screening tool for PUSM available in French-language contexts.

METHOD

This study explored the psychometric validity of the French version of the BSMAS in a sample of 247 adolescents, who were either psychiatric inpatients (the hospitalized group, n = 123) or recruited in local high schools (the community group, n = 124).

RESULTS

The adolescents in the sample reported an increase in their social media use during the COVID-19 pandemic. This increase was more pronounced in the hospitalized group. Confirmatory factorial analysis showed an excellent fit, very good internal consistency and established convergent validity for the French version of the BSMAS. A total of 15.4% of the hospitalization group and 6.5% of the community group met the recommended clinical cutoff of 24 on the BSMAS, suggesting problematic use of social media.

CONCLUSIONS

The French version of BSMAS is a psychometrically validated and clinically useful tool to screen for PUSM in adolescents.

The mediating role of anxiety and depression between problematic social media use and bulimia nervosa among Lebanese university students

Background

Bulimia nervosa (BN) is a disorder that is characterized by binge eating and inappropriate compensatory behavior to control weight. The aim of this study was to evaluate the mediating role of anxiety and depression between problematic social media use (PSMU) and BN among a sample of Lebanese university students.

Methods

This cross-sectional study was carried out between July and September 2021; a total of 363 university students was recruited through convenience sampling. The PROCESS SPSS Macro version 3.4, model four was used to test the indirect effect and calculate three pathways. Pathway A determined the regression coefficient for the effect of PSMU on mental health issues (depression/anxiety); Pathway B examined the association between mental health issues on BN, and Pathway C’ estimated the direct effect of PSMU on BN. Pathway AB was used to calculate the indirect effect of PSMU on BN via depression/anxiety.

Results

Results showed that depression and anxiety partially mediated the association between PSMU and BN. Higher levels of PSMU were associated with more depression and anxiety; higher depression and anxiety were associated with more BN. PSMU was directly and significantly associated with more BN. When entering anxiety (M1) then depression (M2) as consecutive mediators in a first model, the results showed that only depression mediated the association between PSMU and bulimia. When taking depression (M1) then anxiety (M2) as consecutive mediators in a second model, the results showed that the mediation PSMU → Depression → Anxiety → Bulimia was significant. Higher PSMU was significantly associated with more depression, which was significantly associated with more anxiety, which was significantly associated with more bulimia. Finally, higher PSMU was directly and significantly associated with more bulimia

Conclusion

The current paper highlights the relationship that social media use has on BN and other aspects of mental health such as anxiety and depression in Lebanon. Future studies should replicate the mediation analysis conducted in the current study while taking into account other eating disorders. Additional investigations of BN and its correlates must strive to improve the comprehension of these associations’ pathways through designs that allow to draw temporal frameworks, in order to efficiently treat this eating disorder and prevent its negative outcomes.

Bulimia nervosa, an eating disorder, is characterized by an impulsive consumption of food in a short period of time, followed by behaviors that compensate the eating such as vomiting or excessive exercise in order to avoid weight gain. Individuals with problematic social media use were found to have higher levels of bulimia symptoms. Symptoms of bulimia can also be associated with both depression and anxiety. The aim of the current study was to examine the mediating role of anxiety and depression between problematic social media use and bulimia nervosa. The results of our study found that problematic social media use was directly associated with more bulimia nervosa and also associated with higher depression and anxiety, both of which were associated with bulimia nervosa. Tackling associated disorders may help reduce symptoms of bulimia nervosa. Clinicians should carefully examine these associations while assessing and implementing treatment plans.

Work addiction, work engagement, job burnout, and perceived stress: A network analysis

Introduction

Recently, the network theory of mental disorders has been used to conceptualize work addiction as a dynamic system of symptoms in direct relationships. This study aimed to extend previous work by investigating the direct relationships of work addiction symptoms with dimensions of work engagement, job burnout, and perceived stress.

Methods

These phenomena were measured with the Bergen Work Addiction Scale, the Utrecht Work Engagement Scale, the Maslach Burnout Inventory-General Survey, and the Perceived Stress Scale. The sample comprised 676 working Poles with a mean age of 36.12 years (SD = 11.23). The network analysis followed the guidelines for estimating psychological networks from cross-sectional data.

Results

Work engagement and job burnout were more closely associated with each other than with work addiction which supports the notion that engagement and burnout represent polar opposites of the same construct and that work addiction is a separate phenomenon, related to both work engagement and job burnout via specific pathways. The symptoms of work addiction were connected with other phenomena through four direct relationships: (1) mood modification-absorption, (2) mood modification-stress, (3) withdrawal-absorption, and (4) problems-exhaustion.

Discussion

These findings narrow down and specify hypotheses regarding potential mechanisms leading from engagement to addiction and from addiction to burnout. The possible mechanisms focus on the absorption component and mood modification related to efforts focused on alleviating chronic stress and negative emotional states. In turn, problems arising from work addiction may lead to exhaustion. Future studies investigating these mechanisms in detail may enable proper prevention programs and therapeutic interventions.

Psychometric Properties of the Serbian Smartphone Application-Based Addiction Scale (SABAS) and Validation of the English Version Among Non-native English Speakers

The present study evaluated the psychometric properties of the Serbian Smartphone Application-Based Addiction Scale (SABAS) and the original English version of the same scale administered to a Serbian-speaking sample. In Study 1, 599 participants completed Serbian SABAS, with 189 having both test and retest data. Results suggested good internal consistency (α = .81) and test–retest reliability (ICC = .795, p < .001, 95% CI [.731, .844], rtest-retest = .803) of the scale. Convergent validity of the SABAS was evaluated through correlations with the Smartphone Addiction Scale–Short Version (SAS-SV), as well as with anxiety, depression, worry, duration, and purpose of smartphone use. Divergent validity of the SABAS was evaluated through comparing the correlations with entertainment and productive smartphone use. The modified CFA model showed an acceptable fit (χ2(8) = 25.53, p = .001, CFI = .961, TLI = .926, RMSEA = .096, SRMR = .042), confirming the unidimensionality of the SABAS. In the second study, the English SABAS, completed by 335 non-native speakers from Serbia, also showed a good fit of the single-factor model (χ2(9) = 12.56, p = .184, CFI = .990, TLI = .984, RMSEA = .036, SRMR = 0.026), and good psychometric features. Based on the study’s findings, the Serbian version of SABAS is a reliable and valid measure for screening the risk of smartphone addiction. Moreover, the English version can be used among non-native Serbian English speakers.

Does Exercise Addiction Exist Among Individuals Engaged in Team-Based Exercise? A Position Paper

Exercise addiction is a term used to describe dysfunctional exercise behavior characterized by the classic symptoms of addictions, which eventually result in physical, psychological, or social harm to the affected individual. While well over 1000 peer-reviewed papers on problematic exercise have been published, very few studies have explored the conceptual differences between team-based and individual-based exercise, and no previous study has critically addressed this issue. The rationale for this distinction is that team-based exercise is typically organized and scheduled by others with little or no control over its timing by the individual team member. On the contrary, individual-based exercise can be self-scheduled. Consequently, more (total) control over its timing facilitates the satisfaction of craving-induced urges characterized by an addiction. It is posited that exercise addicts, in general, are “lone wolves” in the context of their addiction. Therefore, being addicted to exercise in team sports is only possible if the individual resorts to additional individually-controlled exercise above and beyond team-based training. To support this position, the present paper briefly reviews the few studies conducted in this area and examines how their results match the diagnostic interpretation of “addiction.” The present position paper highlights that “control” over the addictive behavior, in this case, exercise, is an important marker in the potential for the risk of exercise addiction. Therefore, future studies should consider that team-based exercise assigns little control to the individual. However, the extent to which additional individual-based exercise occurs and poses a risk of addiction within team exercises merits further research attention.

Short version of the smartphone addiction scale: Measurement invariance across gender

The Smartphone Addiction Scale Short Version (SAS-SV) has been widely used in research, but little is known about the measurement invariance across gender. The current study measured SAS-SV invariance between male and female college students in a sample of 1112 participants. Single- and multiple-group confirmatory factor analyses (CFAs) of smartphone addiction symptom ratings were conducted using R program with RStudio. SAS-SV was psychometrically robust in measuring the severity of smartphone addiction among college students, as well as the gender-based invariance. The differences in SAS-SV between male and female participants were likely to represent true gender differences, and meaningful comparisons could be made.

Determination of the psychometric properties of the digital addiction scale for children

AIM

To determine the psychometric properties of the Digital Addiction Scale for Children.

DESIGN AND METHOD

This methodological study included 506 children aged 9-12 years. Data were collected using the child and family information form, the digital addiction scale for children and the digital game addiction scale for children. The data were evaluated using confirmatory factor analysis Cronbach's alpha, convergent validity, and gender-based measurement invariance analysis. Confirmatory factor analysis was applied using Mplus 8.7 with robust maximum likelihood estimation procedures.

RESULTS

Confirmatory factor were performed for construct validity. The scale was found to have good model fit indicators. The factor loadings of all the components were found to be >0.40. Convergent validity of Digital addiction scale for children and digital game addiction scale showed a significant positive high correlation. The total Cronbach alpha value of the scale was determined as 0.94, and the Cronbach alpha values of the subscales as Interpersonal 0.89, and Intrapersonal 0.91.

CONCLUSION

The use of the digital addiction scale for children was determined to be a valid and reliable scale for the screening of digital device use and digital addiction in a Turkish sample.

PRACTICE IMPLICATIONS

Nurses and other health professionals have an important role in detecting situations that put children's health at risk and promoting positive behaviors. It is especially important that school health nurses use valid and reliable tools that can determine children's digital addictions. Since this scale is easy and practical, it is thought that it will contribute significantly to the literature.

Perceived effectiveness of therapeutic community model as a rehabilitation approach for Sri Lankan individuals with substance use disorder

Purpose

This study aims to evaluate the perceived effectiveness of residential treatment which follows the therapeutic community (TC) model for Sri Lankan individuals with substance use disorder (SUD).

Design/methodology/approach

A descriptive cross-sectional study was carried out in two selected residential treatment centers which follow the TC model as a rehabilitation approach. All the clients of the selected residential treatment centers were invited to take part in the study and data were collected from 75 consented male participants using an interviewer-administered questionnaire. The perceived effectiveness of the residential treatment was assessed using the Treatment Effectiveness Assessment instrument. Data were analyzed using descriptive statistics.

Findings

Most of the participants were Sinhalese (98.7%, n = 74) with a mean age of 27.0 ± 6.0 years. The average duration in which participants stayed at selected centers was 8.0 ± 4.0 months. Most of the participants reported that the encouragement during the program was sufficient (89.3%, n = 67), psychological support was satisfactory (89.3%, n = 67), freedom (69.5%, n = 52) and facilities were adequate (76.0%, n = 57) within the program. A higher proportion of participants said that the counselors and program guides were friendly (80.0%, n = 60), and participants were allowed to communicate with their family with restrictions (92.0%, n = 69). The mean perceived effectiveness score (score range 1–40) was 34.0 ± 7.0 and the four domain scores (score range 1–10) were substance use (9.0 ± 2.0), health (8.0 ± 2.0), lifestyle (9.0 ± 2.0) and community (9.0 ± 2.0). The majority (88.0%, n = 66) of the participants perceived a high level of treatment effectiveness.

Originality/value

There is a paucity of empirical evidence on effectiveness of TC model for individuals with SUD in South Asian countries including Sri Lanka. The findings of this study highlight that the participants perceived higher effectiveness of the residential treatment which follows the TC approach for Sri Lankan individuals with SUD.

Deconstructing the components model of addiction: an illustration through "addictive" use of social media

The components model of addiction posits that all addictions share six components, namely salience, tolerance, mood modification, relapse, withdrawal, and conflict. This highly influential model has resulted in the development of numerous psychometric instruments that measure addictive behaviors according to these criteria. However, recent research suggests that, in the context of behavioral addictions, certain components constitute peripheral features that do not distinguish non-pathological from pathological behavior. Using "addictive" use of social media as a representative example, we examined this perspective by testing whether these six components actually assess central features of addiction, or whether some of them constitute peripheral features that are not indicative of a disorder. Four independent samples totaling 4,256 participants from the general population completed the Bergen Social Media Addiction Scale, a six-item psychometric instrument derived from the components model of addiction to assess social media "addiction". By performing structural equation modeling and network analyses, we showed that the six components did not form a unitary construct and, crucially, that some components (i.e., salience, tolerance) were not associated with measures assessing psychopathological symptoms. Taken together, these results suggest that psychometric instruments based on the components model conflate central and peripheral features of addiction when applied to behavioral addictions. This implies that such instruments pathologize involvement in appetitive behaviors. Our findings thus call for renewing the conceptualization and assessment of behavioral addictions.

The Role of an Individual and a Situation in Explaining Work Addiction: Disclosing Complex Relations

The current study aimed to test the relationships between perfectionism, type A personality, and work addiction via mediator of extrinsic work motivation and moderators of both parent work addiction and demanding organization profiles. A cross-sectional study was carried out using an online self-report questionnaire. A sample consisted of 621 employees working in different Lithuanian organizations that were selected on the basis of the convenience principle. Prior to testing the hypotheses, latent profile analysis (LPA) was conducted in order to identify the subgroups of participants based on situational variables. Two profiles (i.e., 'less addicted parents' and 'more addicted parents') for parent work addiction and tree profiles (i.e., 'slightly demanding organization', 'moderately demanding organization', 'highly demanding organization') for a demanding organization emerged from LPA. The hypotheses were tested using structural equation modeling. Main results revealed that direct relationships between perfectionism, type A personality, and work addiction were positive and stronger for those working in highly demanding organizations. Indirect relationships between perfectionism, type A personality, and work addiction (via extrinsic motivation) were positive and stronger for employees who have parents with higher levels of work addiction. Future researchers and those who implement preventive practices should be aware that personal factors can be the first impetus for work addiction, and the second one (comprised of situational factors in a family and organization) can enhance the expression of these personal factors and stimulate the development of work addiction.

Prevalence and Clinical Significance of Psychiatric Comorbidities With Gambling Disorder in 12 Clinical Settings in Japan

OBJECTIVES

This study investigated the occurrence rate of psychiatric disorders comorbid with gambling disorder, and their clinical significance in the severity of gambling disorder using a retrospective cross-sectional design.

METHODS

The medical records of 359 patients (men/women, 326/33; median age, 37.0 years) with gambling disorder as the primary disorder from 12 treatment facilities specializing in addiction (9 clinics and 3 hospitals) in Japan were studied. We investigated patients' comorbid psychiatric disorders, demographic and clinical characteristics, and the severity of gambling disorder based on criteria from the Diagnostic and Statistical Manual of Mental Disorders, fifth edition.

RESULTS

Of all patients, 58.3% had comorbidities (tobacco use disorder, 20.9%; alcohol use disorder, 13.9%; major depressive disorder, 13.1%; behavioral addictions, 13.1%; attention-deficit hyperactivity disorder, 6.1%; etc.). Statistical analysis indicated that as the number of comorbid psychiatric disorders increased, psychosocial problems also increased (e.g., proportion of adverse childhood experiences [ P < 0.001], and history of suicide attempts [ P = 0.009]). In the multivariable analysis, behavioral addictions ( β = 0.666; t = 3.151) were significantly associated with gambling disorder severity. Specifically, individuals with gambling disorder comorbid with behavioral addictions including kleptomania, excessive buying, and excessive sex-related behavior may present more severe gambling problems than those without behavioral addictions.

CONCLUSIONS

Patients with gambling disorder should be carefully assessed for psychiatric comorbidities and interventions should reflect the individual diagnosis.

Nomophobia among university students: Prevalence, correlates, and the mediating role of smartphone use between Facebook addiction and nomophobia

Nomophobia ('no mobile phone phobia') has been growing issue worldwide in recent years and has been associated with a number of psychological and behavioral health-related problems. However, few studies have examined nomophobia in Bangladesh. Therefore, the severity and correlates of nomophobia, and the mediating role of smartphone use between Facebook addiction and nomophobia was investigated. A cross-sectional study utilizing 585 university students was conducted employing a convenience sampling method. Data were collected using a survey in March 2022. The survey comprised questions related to socio-demographics, behavioral health, academic performance, nomophobia, smartphone addiction, Facebook addiction, insomnia, and depression. The mean score of nomophobia was 88.55 out of 140 (±21.71). The prevalence was 9.4% for mild nomophobia, 56.1% for moderate nomophobia, and 34.5% for severe nomophobia. First-year students had higher levels of nomophobia than other years. Significant predictors for nomophobia included daily duration of smartphone time, psychoactive substance use, and being in a relationship. Nomophobia was significantly associated with smartphone addiction, Facebook addiction, insomnia, and depression. Moreover, smartphone addiction significantly mediated the relationship between Facebook addiction and nomophobia. Strategies that help reduce daily smartphone time, and reduce psychoactive substance use might help reduce nomophobia prevalence among university students.

The influence of Facebook intrusion and task context on cognitive control

Social networking sites, especially Facebook, have become increasingly popular over the past decades. However, besides the benefits of using Facebook, negative effects in the form of Facebook intrusion are also increasingly pointed out. Much of the research focuses on personality, emotional and social factors related to Facebook intrusion. However, there has been limited research on the relationship between this type of behavioural addiction and cognitive functioning. Consequently, the current study aimed to verify the relationship between Facebook intrusion and cognitive control in light of the dual mechanism of cognitive control model. Additionally, the study aim was to verify the impact of the Facebook-related context on cognitive control (proactive and reactive modes) compared to neutral and positive contexts. The participants (N = 82 young adults, 57 female, M = 22.24 years, SD = 2.67 years, age range 18-35 years) were divided into two groups based on their level of Facebook intrusion. The Facebook intrusion scale was used to assess the level of Facebook intrusion. The AX-CPT task was used to assess proactive and reactive control modes in three task contexts: Facebook-related, neutral and positive. The current study results show that the participants with high Facebook intrusion had greater reactive control than participants with low Facebook intrusion. The differences between Facebook-related, neutral context and positive context were not found. However, the present findings demonstrate the interaction between Facebook intrusion and task context in cognitive control. More specifically, participants with low Facebook intrusion had greater proactive control than participants with high Facebook intrusion in the Facebook-related and positive context.

Exercise behaviour and body esteem of gym-goers in india

Exercise dependence is described as exercise which is harmful if engaged compulsively and excessively. The present study aims to investigate differences in categories of exercise behaviours and areas of body esteem in gym-goers in India across genders. The study used a cross-sectional design, and the sample consisted of 291 gym-goers (females = 146; males = 145) The Exercise Dependence Scale- 21 (EDS-21) and Body Esteem Scale-Revised (BES-R) was administered to the gym-goers in India after seeking informed consent. The obtained data were statistically analysed using descriptive statistics and multivariate analysis of variance. The results of the study indicated that there was a significant difference in the three categories of exercise behaviours and three areas of body esteem in male gym-goers. However, such similar differences were not found in female gym-goers. The differences found in body esteem for the male gym-goers in certain areas suggest how exercise has an impact on body image. For female gym-goers, we can see that irrespective of the category they belong to, there is no difference in the areas of body esteem. We can understand such findings with the sociocultural model of excessive exercise given by White and Halliwell (DOI: 10.1016/j.bodyim.2010.02.002) where perceived sociocultural pressure predicts excessive exercise, which is mediated by body image. Strengths and limitations of the study are discussed. Future research in India based on qualitative and longitudinal designs are warranted.

Service Providers’ Perceptions of Substitute Addictions in the Western Cape, South Africa

Globally little is known regarding substance use service providers’ perceptions of substitute behaviours and this significant gap could hinder service provision and recovery outcomes. Semi-structured focus group discussions (including 22 service providers across five sites) were conducted in residential treatment facilities in the Western Cape, South Africa. Service providers recognised substances (e.g. cigarettes and caffeine) and behaviours (e.g. gambling, eating, love, sex, shopping, exercise, and gaming) as potential substitutes. Identified substitute motives included managing cravings; self-medication; filling the experiential void of the primary substance, and time-spending. Concurrent behaviours and addictions were believed to be a key mechanism underlying substitution however, service providers did not uniformly screen for co-occurring behavioural addictions. Substitute behaviours were primarily considered a pathway to relapse and service providers emphasised prevention, detection and family education. To suitably intervene, screening for co-occurring behaviours should be an integral part of the assessment of those presenting for substance use treatment.

A preliminary study into internet related addictions among adults with dyslexia

In recent decades, studies have investigated associations between learning disorders such as Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD), and the various types of internet addictions, ranging from general internet addiction (GIA) to specific internet addictions such as social media addiction (SMA) and internet gaming disorder (IGD). However, to date, no study has investigated such internet addictions among persons with dyslexia. The present study aimed to investigate whether differences exist between adults with dyslexia and controls in terms of GIA, SMA and IGD. A total of 141 adults with dyslexia and 150 controls (all UK based) were recruited. Controlling for age, gender, marital status, employment, and income levels, it was found that adults with dyslexia had higher levels of GIA and IGD compared to controls. However, these participants did not show any significant difference in terms of SMA. The results indicate that internet addictions may have a larger ambit for learning disorders beyond just ASD and ADHD and could be a hidden problem for these individuals.

Psychometric validity and the appropriateness of tolerance as a criterion for internet gaming disorder: A systematic review

Tolerance is a controversial but still an omnipresent criterion in measuring problematic gaming and Internet Gaming Disorder (IGD). Despite criticisms, a systematic review of its suitability has not been conducted until now. The aim of this study was to assess the evidence of psychometric validity and the appropriateness of tolerance as a criterion for IGD. A total of 61 articles were included in the review, 47 quantitative, 7 qualitative studies,plus 7 studies that introduce potential item wordings for operationalizing tolerance. Results showed that the tolerance item tends to have acceptable to high factor loadings on the single IGD factor. While tolerance sometimes did not adequately differentiate the engaged gamers from those with a probable disorder, it was endorsed at medium to high levels of IGD severity and had a good performance in the interviews. It, however, showed weak relations with distress and well-being. In qualitative studies, tolerance as currently defined by DSM-5 and measured by questionnaires (i.e., increasing amounts of time spent on gaming) was almost unequivocally rejected by gamers. The solid performance of tolerance in psychometric studies was probably due to deficiencies of the IGD construct, which also contains other disputed criteria. Tolerance lacks relevance in measuring IGD and care should be taken when using and interpreting IGD measures with this criterion.

Validation of the Polish Problematic Tinder Use Scale and Its Relationship with Safe Sex Behaviors

INTRODUCTION

Online dating is a common phenomenon. The manageability and access of the application allows people to quickly reach many potential partners, which can increase risky sexual behaviors. The Problematic Tinder Use Scale (PTUS) was developed and validated in a Polish population by analyzing the reliability, validity, and factor structure of the responses given by Polish-speaking participants.

METHODS

Two samples of adult Tinder users were recruited online. The first study aimed to perform the reliability coefficient Cronbach's, interrater analysis, exploratory, and confirmatory factor analysis. The second sample was recruited to investigate the factor structure by combining it with the Safe Sex Behavior Questionnaire (SSBQ). The sociodemographic data, such as hours of use and number of dates, were also investigated.

RESULTS

The Polish participants' responses to the PTUS (sample 1: N = 271, sample 2: N = 162) revealed the one-factor structure of the tool. The reliability of the measurement was α = 0.80. The construct validity was confirmed. The results showed a significant, negative, and weak correlation between the PTUS and SSBQ scores and their subscales: risky sexual behaviors (r = -0.18), condom use (r = -0.22), and avoidance of body fluids (r = -0.17). Moreover, the number of partners met in the real world had a statistically significant, moderate relationship with the PTUS scores.

CONCLUSIONS

The PTUS measurement is valid and reliable for the Polish population. The findings highlight the need for harm prevention strategies related to potentially addictive Tinder use, as well as the possible risky sexual behaviors associated with dating app use.

Psychometric Properties of Screening Instruments for Social Network Use Disorder in Children and Adolescents: A Systematic Review

IMPORTANCE

Children and adolescents spend considerable time on the internet, which makes them a highly vulnerable group for the development of problematic usage patterns. A variety of screening methods have already been developed and validated for social network use disorder (SNUD); however, a systematic review of SNUD in younger age groups has not been performed.

OBJECTIVE

To review published reports on screening tools assessing SNUD in children and adolescents with a maximum mean age of 18.9 years.

EVIDENCE REVIEW

To identify instruments for the assessment of SNUD, a systematic literature search was conducted in the databases PsycINFO, PubMed, Web of Science, PsycArticles, and Scopus. The final search took place on May 2, 2022. Psychometric properties of available tools were examined and evaluated to derive recommendations for suitable instruments for individuals up to 18 years of age.

FINDINGS

A total of 5746 publications were identified, of which 2155 were excluded as duplicates. Of the remaining 3591 nonredundant publications, 3411 studies were assessed as not relevant after title and abstract screening. A full-text analysis of 180 remaining studies classified as potentially eligible resulted in a final inclusion of 29 studies revealing validation evidence for a total of 19 tools. The study quality was mostly moderate. With regard to validation frequency, 3 tools exhibited the largest evidence base: Social Media Disorder Scale (SMDS), the short version of the Bergen Facebook Addiction Scale, and Bergen Social Media Addiction Scale-Short Form (BSMAS-SF). Among these, 1 study tested a parental version (SMDS-P) for its psychometric properties. Taking all criteria into account, the strongest recommendation was made for the SMDS and BSMAS-SF.

CONCLUSIONS AND RELEVANCE

Results suggest that the SMDS-SF and BSMAS-SF were appropriate screening measures for SNUD. Advantages of the SMDS are the availability of a short version and the possibility of an external parental rating.

Depression and Internet Gaming Disorder among Chinese Adolescents: A Longitudinal Moderated Mediation Model

Internet gaming disorder (IGD) is significantly associated with depression across previous studies, and significantly affects the development of mental health among Chinese adolescents. In this two-wave longitudinal research, we tested the mediating role of maladaptive cognition and the moderating role of mindfulness in the linkage between depression and IGD among Chinese adolescents (N = 580, 355 females, average age = 15.76 years, SD = 1.31) who completed questionnaires. Results of regression-based analyses showed that depression was positively related to IGD. Maladaptive cognition significantly mediated the link between depression and IGD. Moreover, mindfulness moderated the second part of the mediation process. Specifically, as the level of mindfulness increased, the influence of depression on the future IGD through maladaptive cognition was weakened. The present study demonstrates the key roles of maladaptive cognition and mindfulness in the link between depression and IGD, and further supports the cognitive-behavioral model of pathological Internet use.

How is the problematic smartphone use affected by social support? A research model supported by the mediation of Ikigai

Social support and ikigai (making life worthwhile) have positive effects on problematic smartphone use and are seen to be related to each other. However, what mediates these relationships has not been adequately analyzed. This study aims to examine how the effect between social support and problematic smartphone use occurs by suggesting the mediator role of ikigai. The study was designed as quantitative and cross-sectional, and 1189 university participants aged 18 and over were reached online. The multidimensional scale of perceived social support, ikigai-9 scale, smartphone application-based addiction scale and sociodemographic information form were used as data collection tools in the study. The data obtained were carried out using SPSS 24 and Amos 25 statistical programs. Established hypotheses were tested with correlation, multiple regression and mediation analyzes. The results confirmed that social support was positively associated with ikigai, and ikigai was negatively associated with problematic smartphone use. In addition, interaction analyzes found that ikigai had a mediating effect. These findings show the importance of implementing specific applications based on the meaning and purpose of life (ikigai), especially for vulnerable groups, to minimize the problems that may arise with the excessive use of smartphones.

Family Matters More Than Friends on Problematic Social Media Use Among Adolescents: Mediating Roles of Resilience and Loneliness

Problematic social media use (PSMU) among adolescents has raised global concern in the current digital age. Despite the important role of perceived social support in adolescents' PSMU has been examined, possible different influences between perceived support from family and friends are still unknown. To address the gap, the present study aimed to examine how perceived support from family and friends is associated differently with PSMU and the mediating roles of resilience and loneliness therein. A sample of 1056 adolescents was recruited to complete standard questionnaires. Mediation analysis showed that resilience and loneliness mediated this association partially between perceived support from family and PSMU but totally between perceived support from friends and PSMU. Further, ANOVA-based analysis showed that influences of perceived support from family and friends on PSMU were mutually independent, and there was no interaction between them. Our results not only highlight different and independent impacts of perceived support from family and friends on PSMU, but also clarify the mediating mechanisms linking perceived social support to adolescent PSMU.
