Validation of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and Its Association with Functional Impairment in Brazilian Gamers.

INTRODUCTION: Despite the growing recognition of gaming disorder as a mental disorder, there is still debate about how it should be best screened for. This is especially relevant in countries where prevalence studies that could support evidence-based policymaking are still to be conducted. This study aims to evaluate the psychometric properties of the Brazilian Portuguese version of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and to explore its association with functional impairment. METHODS: An online convenience sample of 805 Brazilian adults who reported playing games completed the adapted version of IGDT-10 and World Health Organization Disability Assessment Schedule 2.0, as well as the Problematic Internet Use Questionnaire, the Center for Epidemiologic Studies-Depression Scale, the Rosenberg Self Esteem Scale and socio-demographic questions. RESULTS: The Brazilian Portuguese version of IGDT-10 demonstrated a unidimensional structure in both confirmatory and exploratory factor analysis, with satisfactory internal consistency and adequate temporal stability. Participants who scored five or more on IGDT-10 presented higher levels of functional impairment compared to those who scored positive for four symptoms or less. The difference between the two groups was statistically significant and showed a moderate effect size. Network analysis showed a direct connection between IGDT-10 and functional impairment, and identified "negative consequences" as the most relevant item connecting these variables. CONCLUSION: The IGDT-10 is a brief, easy-to-understand, valid, and reliable instrument, proving to be a suitable candidate for screening gaming disorder in future epidemiological studies.

Problematic Internet, Smartphone, and SMS Use among Adults: Shared and Unique Predictors.

BACKGROUND: Although a surge of interest has recently emerged in investigating the simultaneous problematic use of various technology-based tools, the findings are still inconclusive. The present web-based survey aimed at examining whether (a) personality traits, coping strategies, and sociodemographics are associated with problematic internet, smartphone, and SMS use among Greek users and (b) personality traits mediate the relationship between maladaptive coping strategies and problematic use of the three media. STUDY DESIGN: A cross-sectional study. METHODS: A convenience and snowball sample of 1016 participants (84.4% female, mean age of 30.3 years) completed the Problematic Internet Use Questionnaire-9 (PIUQ-9), the Mobile Phone Problem Use Scale (MPPUS), the Self-Perception of Text Message Dependency Scale (STDS), the Personality Diagnostic Questionnaire 4+(PDQ-4+), and the Brief Coping Orientation to Problems Experienced Inventory (Brief COPE). RESULTS: Shared predictors between problematic use of the three technology-based tools were younger age and low educational level, the coping strategy of substance use, and the narcissistic, avoidant, and dependent personality disorders. Predictors of problematic internet and smartphone use were coping strategies of emotional support, self-distraction, and behavioral disengagement. According to structural equation models (SEM) models, cluster C personality disorders fully mediate the relationship between maladaptive coping strategies and problematic use of technology-based tools. CONCLUSION: Addressing factors that predispose (i.e., personality traits), precipitate, or maintain problematic use (i.e., coping strategies) can lead to effective and cost-saving preventive (i.e., screening of vulnerable groups) and therapeutic efforts (i.e., teaching adaptive coping strategies).

Psychometric Properties of the Nine-Item Problematic Internet Use Questionnaire in a Brazilian General Population Sample.

Objective: The goal of the study is to adapt and examine the psychometric properties of the Brazilian version of the nine-item Problematic Internet Use Questionnaire (PIUQ-SF-9). Methods: A convenience sample of Brazilian internet users aged between 18 and 89 years (72.7% female, mean age 38.7 years ± 13.5) was recruited online from September 2018 to July 2019 (test sample = 1,525; retest sample = 237). Participants responded to the adapted version of the PIUQ-SF-9, as well as the Center for Epidemiologic Studies-Depression Scale (CES-D-10) and sociodemographic questions. Results: A bifactor model with one general factor and three specific dimensions (obsession, neglect and control disorder) yielded the best fit indices [χ2 = 67.66, df = 15, CFI = 0.99, TLI = 0.99, RMSEA = 0.048 (0.037-0.060), RMSEA p close = 0.587 and SRMR = 0.01]. McDonald's hierarchical omega coefficient was 0.76 for the general factor and varied between 0.16 and 0.33 for the specific dimensions. The intraclass correlation coefficient was 0.73 for the general factor and varied between 0.64 and 0.72 for the specific dimensions. The MIMIC model supported the scale's construct validity as the relationship of the predictors (age, time spent online, self-perception of problematic internet use, and depression symptoms) with the PIUQ-SF-9 factors was in line with the assumptions based on the literature. Conclusion: PIUQ-SF-9 seems to be a brief and culturally validated instrument with sound psychometric properties to be used in future studies on problematic internet use in the Brazilian population.

Validation of the Opioid Overdose Knowledge (OOKS) and Attitudes (OOAS) Scales in French, Spanish, and German Languages, among a Sample of Opioid Users.

INTRODUCTION: Improving the knowledge and attitudes of people facing an opioid overdose is one of the key prevention measures for reducing overdose occurrence and severity. In this respect, the Opioid Overdose Knowledge Scale (OOKS) and Opioid Overdose Attitudes Scale (OOAS) have been developed and validated in English to assess and improve knowledge and attitudes of opioid users and their families and care providers, in case of an overdose. Here, the OOKS and OOAS scales have been translated into French, Spanish, and German, and the different versions of the 2 scales have been assessed regarding their psychometric properties. METHODS: The translation procedure of the scales was based on the international recommendations, including a back translation by a native English speaker. Subsequently, 80 (Spain: 29, France: 27, Germany: 24) former or current heroin users, aged from 20 to 61 years (M = 39.4 ± 9.23), completed the OOKS and OOAS versions of their native language, in test-retest, without specific between-assessment training. Internal consistency was assessed using Cronbach's α, while test-retest reliability was assessed using intraclass correlation coefficient (ICC). The correlation between the OOKS and OOAS scores of a same language was assessed using Spearman's (ρ) coefficient. RESULTS: Internal consistency of the OOKS was found to be good to very good, with Cronbach's α ranging from 0.62 to 0.87. Test-retest reliability was also very good, with ICCs ranging from 0.71 to 0.82. However, results were less reliable for the OOAS, as internal consistency was questionable to acceptable, with Cronbach's α ranging from 0.12 to 0.63, while test-retest ICCs were very good for the French (0.91) and Spanish (0.99) versions and barely acceptable for the German version (0.41). No significant correlation was found between the OOKS and OOAS scores, irrespective of the version concerned. CONCLUSION: While satisfactory results were found for the 3 versions of the OOKS, results on the OOAS were relatively inconsistent, suggesting a possible gap between knowledge and attitudes on overdose among opioid users.

Pathological Traits Associated to Facebook and Twitter among French Users.

BACKGROUND: With a growing number of users, social networking sites have been the subject of numerous recent studies, but little investigation has been given to their problematic use. OBJECTIVES: Our main objective was to study the relationship between psychopathological variables (i.e., personality traits, depressive and anxiety symptoms, and stress) and problematic Facebook and Twitter use. PARTICIPANTS AND METHOD: A sample of 1068 Internet users (Mage = 26.64; SD = 9.5) has been recruited online. Participants completed scales exploring problematic Facebook and Twitter use, and psychopathological variables. RESULTS: Problematic Facebook and Twitter use were predicted by different pathological personality traits, regrouped in clusters in our study. Depressive and anxiety symptoms were also predictive of problematic Facebook and Twitter use but only stress explained problematic Facebook use. Gender differences have been observed. DISCUSSION: This study highlights the relationship between depression, anxiety, stress, pathological personality traits, and problematic Facebook and Twitter use. Significant differences have been retrieved between these two uses and their relationship to psychopathology. Future research should also explore the causal relationship between social networking sites use and psychopathology and consider gender.

Problematic Internet Use, Psychopathology, Defense Mechanisms, and Coping Strategies: a Cross-Sectional Study from the United Arab Emirates.

A number of studies point to a demonstrated relationship between problematic Internet use (PIU) and psychopathological variables. However, explorations of PIU in relation to defense mechanisms and coping strategies remain rare. The present study sought to determine the extent of PIU among a sample of college-aged young adults resident in the United Arab Emirates. The relationship of PIU to two psychopathological variables (depression and low self-esteem) and two psychological variables (defense mechanisms and coping strategies) were examined. A sample of 697 Emirati participants aged between 18 and 33 years of age completed assessments of PIU, socio-demographic, psychopathological, and psychological variables. A total of 67.3% exhibited PIU. Problematic users produced higher scores for maladaptive coping strategies and for the use of immature, neurotic, and autistic fantasy defenses. Regression analyses revealed that PIU was predicted by the mature, immature, and autistic fantasy defenses as well as, negatively by adaptive coping, and positively by maladaptive coping. These differed when the analyses were repeated on gender-stratified samples. Given that this initial prevalence estimation suggests that PIU may be a substantial issue in this region of the world, future research should examine the mental health risk factors related to PIU, particularly their causal relationships.

Psychometric Evaluation of the Nine-Item Problematic Internet Use Questionnaire (PIUQ-9) in Nine European Samples of Internet Users.

Objectives: The nine-item Problematic Internet Use Questionnaire (PIUQ-9) is a brief self-report screening instrument for problematic internet use. The main objective of the present study was to explore the psychometric properties of the PIUQ-9 among nine different language-based samples of European internet users (Italian, German, French, Polish, Turkish, Hungarian, English, and Greek). Methods: The total sample comprised 5,593 internet users (38.1% men), aged between 18 and 87 years (M = 25.81; SD = 8.61). Via online recruitment, participants completed the PIUQ-9, the Brief Symptom Inventory (BSI) and items about time spent online. Results: Confirmatory factor analysis demonstrated that the bifactor model with one general factor (i.e., general problem) and two-specific factors (i.e., obsession and neglect + control disorder) yielded acceptable or good fit indices in all subsamples except for one. The common variance index in the bifactor model indicated that the general problem factor explained from 57.0 to 76.5% of common variance, which supports the presence of a strong global factor. According to the multiple indicators multiple causes (MIMIC) model, psychiatric symptoms had a moderate-to-strong direct effect on the general problem factor in all subsamples, ranging from ß = 0.28 to ß = 0.52 supporting the construct validity of the scale. Furthermore, in a majority of the subsamples, time spent online during the weekend had considerably higher effect sizes on the general problem factor than time spent online during weekdays. Conclusion: The present study highlights the appropriate psychometric properties of the PIUQ-9 across a number of European languages and cultures.

Contribution of health motive to cannabis use among high-school students.

The Marijuana Motives Measure (MMM), which is derived from a scale measuring alcohol use motives, has been the main instrument used to explore the role of motives in cannabis use and related problems. Two studies attempted to developed specific cannabis use motives but none of them showed a unique association to cannabis use and problems when controlling for MMM motives. The aim of our study was to examine if additional motives contributed to problematic use beyond MMM motives and psychopathological symptoms. Participants were 249 high-school students who completed the Cannabis Use Disorder Identification Test-Revised (CUDIT-R) assessing cannabis use and problematic use, the MMM and a new scale measuring motives derived from clinical experience with adolescents using cannabis (CED motives), and scales measuring anxiety and depressive symptoms and borderline personality traits. Among the 107 participants using cannabis, 39 reached the cut-off score for problematic cannabis use. Hierarchical multiple regression analyses controlling for psychopathological variables showed that only one CED motives, Health (sleep, form, energy, appetite, health), was a significant predictor of both frequency of use and problematic use symptoms. The importance of Health motive may be linked to the role of depressive symptoms and may have implication for treatment. We suggest to add the Health subscale to the MMM and to further study the role of health motive in both use and dependence.

Religious Beliefs, PTSD, Depression and Resilience in Survivors of the 2010 Haiti Earthquake.

BACKGROUND: This study examines relationships between religious beliefs regarding the origin of the 2010 earthquake in Haiti and posttraumatic symptomatology as well as depressive symptoms and resilience among its survivors. METHOD: We used convenient sampling to recruit participants (n=167). They completed six scales, which had been translated into Haitian Creole, including measures such as the Earthquake Experiences Exposure (EEE), the Peritraumatic Distress Inventory (PDI), the Peritraumatic Dissociative Experience Questionnaire (PDEQ), the PTSD Checklist (PTSD-CL), the Beck Depression Inventory (BDI) and the Connor-Davidson Resilience Scale (CD- RISC) RESULTS: Among our participants, 51% were male, (mean age=30.5, SD=11.03), 92% (n=155) were believers in some sort of supernatural force and 65% (n=108) endorsed the earthquake as a natural phenomenon. There was significant difference in average scores at peritraumatic distress, PTSD symptoms and Resilience measures between those perceiving a divine origin and/or a punishment through the event and those who did not. Peritraumatic responses were best predictors for PTSD (ß=.366, p<.001) and Depression symptoms (ß=.384, p<.001). Voodoo adherents appeared to be vulnerable to depression, but reported superior resilience factors.

Internet addiction symptoms, disordered eating, and body image avoidance.

Internet addiction is an increasing concern among young adults. Self-presentational theory posits that the Internet offers a context in which individuals are able to control their image. Little is known about body image and eating concerns among pathological Internet users. The aim of this study was to explore the association between Internet addiction symptoms, body image esteem, body image avoidance, and disordered eating. A sample of 392 French young adults (68 percent women) completed an online questionnaire assessing time spent online, Internet addiction symptoms, disordered eating, and body image avoidance. Fourteen men (11 percent) and 26 women (9.7 percent) reported Internet addiction. Body image avoidance was associated with Internet addiction symptoms among both genders. Controlling for body-mass index, Internet addiction symptoms, and body image avoidance were both significant predictors of disordered eating among women. These findings support the self-presentational theory of Internet addiction and suggest that body image avoidance is an important factor.
