Aggression and Anabolic-Androgenic Steroid Use Intent in Adolescents: A Longitudinal Study

Background: There is a dearth of longitudinal studies on risk factors for anabolic–androgenic steroid (AAS) use and intent. Objectives: We conducted a longitudinal investigation of factors associated with AAS use intent from age 18 to 19, examining particularly the role of physical and verbal aggression. A sample of Norwegians completed questionnaires containing demographic, AAS use and intent, other addictions, aggression, and health measures at ages 18 (N = 1333, females = 58.9%) and 19 (N = 1277, females = 61.7%). The data were analyzed using descriptive statistics, correlations, and hierarchical multiple regression. Results: Results show that AAS use prevalence increased from 1 person at age 18 to 4 persons at age 19. Intent to use AAS, being male, living alone, and AAS use (all at 18 years) were associated with higher AAS use intent at 19 years. We found no associations between physical or verbal aggression and AAS use intent from ages 18 to 19. Conclusions: Our findings indicate temporal stability in AAS use intent, as well as the influence of demographic and health factors on AAS use intent from ages 18 to 19. Implications of findings for practice and future research are discussed.acceptedVersio

A qualitative study on Norwegian esports students' sleep, nutritional and physical activity habits and the link to health and performance

Aim: This study explored Norwegian esports students’ lifestyle perspectives and habits concerning health and esports performance. Methods and results: Twenty participants between 17 and 21 years of age studying esports were recruited from high schools and folk high schools. The participants were interviewed through Zoom using a semi-structured interview guide, and the data were analyzed using a thematical analysis approach. The emerging themes were: 1) energy and focus, 2) the impact of gaming and esports on sleep, and 3) mental health and lifestyle factors. Proper nutrition, sleep, and reduced intake of energy drinks was considered essential factors for optimal energy and focus. Although this was the consensus, many participants reported skipping breakfast, sub-optimal sleep patterns, and habitual consumption of energy drinks. The participants also reported that sleep was negatively affected by playing right up until bedtime. However, esports matches did not impair sleep due to the time of the day matches were played. Finally, regular physical activity was considered vital for good mental health. Conclusion: The participants acknowledged that proper nutrition, enough sleep, and regular physical activity were essential for optimal health and esports performance. However, many participants reported sub-optimal lifestyle habits, such as skipping breakfast, using blue light-emitting devices before bedtime, and consuming energy drinks. Future research should consider investigating the previously mentioned lifestyle factors to help the esports population develop strategies for improving health and in-game performance.publishedVersio

Not good enough? Further comments to the wording, meaning, and the conceptualization of Internet Gaming Disorder

In their commentary, Kuss, Griffiths, and Pontes (2016) criticize the use of the term “Internet” in the recently proposed diagnosis for Internet Gaming Disorder (IGD) and its use as one of the included diagnostic criteria. We agree with the exclusion of the term “Internet” in the diagnosis, but have some considerations to the comments regarding the nine criteria for IGD. Specifically, we discuss the meaning, the wording, and the importance of the criteria, as well as the importance of distress or functional impairment in the proposed diagnosis. We also address the possibility of categorizing IGD as a subtype of a general behavioral addiction diagnosis

Relationships between exposure to different gambling advertising types, advertising impact and problem gambling

People with gambling problems report more exposure and impact from gambling advertising, although less is known regarding the role of specific advertising types. Data on gamblers (n = 5830, 48.5% women, mean age = 44.27) was collected from a general population cross-sectional survey in Norway (32.7% response rate). We examined if problem gambling was associated with perceived advertising impact (on gambling involvement, awareness, and knowledge) or exposure (via internet, TV, retail outlet, newspaper, and direct advertising). We also investigated if advertising exposure was associated with advertising impact. ANOVAs revealed that problem gambling was associated with increased perceived advertising impact on gambling involvement (ω2 = 0.09, p < .001) and awareness of gambling (ω2 = 0.04, p < .001). Reported exposure to direct advertising increased linearly with problem gambling level (ω2 = 0.04, p < .001), whereas we found small/no differences in exposure to other types of advertising. Multiple regressions revealed that among advertising types, internet advertising was the strongest predictor of perceived advertising impact on gambling involvement (β = 0.1, p < .001). TV advertising was the strongest predictor of advertising impact on knowledge of gambling forms and operators (β = 0.28, p < .001) and awareness of gambling (β = .05, p < .05). Future studies should elucidate how different subtypes of internet advertising impact gambling involvement. Clinicians should assess clients’ experiences with direct advertising and devise interventions for coping. Researchers should be aware that internet and direct advertising allow for more tailored content compared to other advertising types.publishedVersio

Type of musical soundtrack affects behavior in gambling

Abstract Background and aims A long existing notion is that the presence of music might affect gambling behavior. In spite of this, little empirical research on the subject exists. The main aim of the present study was to corroborate and elaborate on the existing findings concerning gambling and music through a laboratory based experiment. Methods A nonclinical sample of 101 undergraduate students (72 females, 29 males) played a computerized gambling task in which either a high-tempo or a low-tempo musical soundtrack was present. Persistence in gambling, reaction time and evaluation of the game comprised the outcome variables. Results Low-tempo music was associated with increased gambling persistence in terms of overall number of bets placed, whereas high-tempo music was associated with intensified gambling in terms of faster reaction time per placed bet. Type of soundtrack was not associated with game evaluation. Discussion Our findings add to the existing knowledge by showing that both low-tempo and high-tempo music can be associated with more risky gambling behavior, the former by increasing gambling persistence and the latter by reducing reaction time for bets placed. Conclusions In sum, the existing studies provide compelling evidence that music can affect various aspects of gambling behavior. These findings may have clinical implications by educating gamblers on the effects of structural mechanisms in gambling on behavior

Tempo in electronic gaming machines affects behavior among at-risk gamblers

Background and aims: Electronic gaming machines (EGM) may be a particularly addictive form of gambling, and gambling speed is believed to contribute to the addictive potential of such machines. The aim of the current study was to generate more knowledge concerning speed as a structural characteristic in gambling, by comparing the effects of three different bet-to-outcome intervals (BOI) on gamblers bet-sizes, game evaluations and illusion of control during gambling on a computer simulated slot machine. Furthermore, we investigated whether problem gambling moderates effects of BOI on gambling behavior and cognitions. Methods: 62 participants played a computerized slot machine with either fast (400 ms), medium (1700 ms) or slow (3000 ms) BOI. SOGS-R was used to measure pre-existing gambling problems. Mean bet size, game evaluations and illusion of control comprised the dependent variables. Results: Gambling speed had no overall effect on either mean bet size, game evaluations or illusion of control, but in the 400 ms condition, at-risk gamblers (SOGS-R score > 0) employed higher bet sizes compared to no-risk (SOGS-R score = 0) gamblers. Conclusions: The findings corroborate and elaborate on previous studies and indicate that restrictions on gambling speed may serve as a harm reducing effort for at-risk gamblers

Problem gambling and the five-factor model of personality: A large population-based study

-Knowledge of the personality characteristics of individuals who develop gambling problems is important for designing targeted prevention efforts. Previous studies of the relationship between the five-factor model of personality and gambling problems were based on small samples not representative of the general population. We estimated differences in Neuroticism, Extroversion, Intellect, Agreeableness and Conscientiousness between non-problem gamblers and individuals with low, moderate and severe gambling problems. Cross-sectional survey Norway 10 081 (51.5% female) individuals aged 16 to 74 years (mean age 46.5 years). The Problem Gambling Severity Index, The Mini-International Personality Item Pool, and demographic variables. Differences between groups of gamblers were analyzed by ordinary least squares regression models separately for each personality trait adjusting for gender, age, cohabitation, level of education and work status. Gamblers with low level, moderate level and severe level of gambling problems differed significantly from non-problem gamblers in Neuroticism (b = 0.16, 0.34 and 0.66 respectively, all p < .001) and Conscientiousness (b = -0.13, -0.27, and -0.44 respectively, all p < .001). Moderate and severe problem gamblers differed from non-problem gamblers in Agreeableness (b = -0.21, p < .001 and b = -0.20, p = .028 respectively). In addition, gambling problems were much more prevalent among men than women, and more prevalent among those who live alone, individuals without tertiary education, and among those who are unemployed or on disability pension. A higher level of problem gambling severity appears to be associated with higher scores on Neuroticism, and with lower scores on Conscientiousness and Agreeableness in the Mini-International Personality Item Pool

Prevalence and Correlates of Problem Gambling in a Representative Sample of Norwegian 17-Year-Olds

We report data collected in a representative sample of 17-year-old Norwegians to investigate prevalence rates of non-problem, risk, and problem gambling, as measured by the Problem Gambling Severity Index (PGSI). In addition, we explored the importance of demographic, personality, motivational, social, and health variables explaining variance in adolescent gambling. Prevalence rates of risk and problem gambling were low but similar to those found in previous studies outside of Norway using the PGSI in adolescent samples. With regard to the relative importance of the various covariates, we found that motivational variables (future gambling intentions, attitudes toward gambling, and gambling-related knowledge) distinguished best between those who did not gamble, non-problem gamblers, and risk and problem gamblers. Furthermore, social variables were important covariates of adolescent gambling; significant associations were found for family and friends’ approval of gambling, parental monitoring, father’s level of education, and having relatives or friends with a history of a gambling disorder. We discuss possible reasons for differences between the covariates with regard to their importance for explaining adolescent gambling and address implications for future research.publishedVersio

The Relationship Between Gambling Problems and the Five-Factor Model of Personality: A Systematic Review and Meta-Analysis

Objectives: The aim of the present meta-analysis was to synthesize results from the association between problem gambling (PG) and dimensions of the five factor model of personality and to identify potential moderators (gambling diagnosis: yes/no, comorbidity: yes/no and trait assessment: four or fewer items vs. five items or more) of these associations in meta-regressions. Methods: Searches were conducted in six databases; Medline, Web of Science, PsychInfo, Google Scholar, OpenGrey, and Cochrane Library (conducted on February, 22, 2021). Included studies: (1) reported a relationship between PG and at least one of the personality traits in the five-factor model, (2) contained information of zero-order correlations or sufficient data for such calculations, and (3) were original articles published in any European language. Case-studies, qualitative studies, and reviews were excluded. All articles were independently screened by two authors. Final agreement was reached through discussion or by consulting a third author. Risk of bias of the included studies was assessed by the Newcastle-Ottawa Scale. Data were synthesized using a random effects model. Results: In total 28 studies, comprising 20,587 participants, were included. The correlations between PG and the traits were as follows: Neuroticism: 0.273 (95% CI = 0.182, 0.358), conscientiousness −0.296 (95% CI = −0.400, −0.185), agreeableness −0.163 (95% CI = −0.223, −0.101), openness −0.219 (95% CI = −0.308, −0.127), and extroversion −0.083 (95% CI = −0.120, −0.046). For all meta-analyses the between study heterogeneity was significant. Presence of gambling diagnosis was the only moderator that significantly explained between-study variance showing a more negative correlation to extroversion when participants had a gambling diagnosis compared to when this was not the case. Discussion: The results indicated some publication bias. Correcting for this by a trim-and-fill procedure showed however that the findings were consistent. Clinicians and researchers should be aware of the associations between personality traits and PG. Previous studies have for example showed neuroticism to be related to treatment relapse, low scores on conscientiousness to predict treatment drop-out and agreeableness to reduce risk of treatment drop-out.publishedVersio

Association between problem gambling and personality traits: a longitudinal study among the general Norwegian population

ObjectiveThe present study investigates the longitudinal relationship between problematic gambling (PG) and the five factor model’s personality traits using autoregressive cross-lagged models.MethodsThe data used in the current study was collected by a national survey in 2013 (n = 10,081) and a follow-up study (n = 5,848) in 2015. PG was measured using Canadian Problem Gambling Index (CPGI) while personality was assessed using Mini-International Personality Item Pool (MINI-IPIP). Participants who completed the CPGI and all the personality items during both waves (n = 2,702) were analysed.ResultsThe results show that neuroticism had positive cross-lagged associations with CPGI. In contrast, conscientiousness and agreeableness in 2013 were found to have inverse cross-lagged effect on CPGI in 2015. Finally, openness and extraversion did not have any cross-lagged associations with CPGI.ConclusionPG poses serious negative implications for the involved individuals as well as their associated close social circle. Hence, it is important to understand predictors of PG for prevention purposes. Personality traits are one of the influential frameworks for examining uncontrolled psychopathological behaviors like PG. The study findings offer significant theoretical as well as practical implications
