Impulsivity and socio-economic status interact to increase the risk of gambling onset among youth

AIMS To determine if impulsivity and socio-economic status (SES) interact to influence gambling onset in youth. DESIGN Longitudinal study of grade 7 students followed for 8 years. SETTING Montréal, Canada. PARTICIPANTS A total of 628 adult students aged 12.6 years on average at cohort inception. MEASUREMENTS Impulsivity and SES (parent education, area deprivation) were collected during secondary school. Age of gambling onset was collected retrospectively when participants were aged 20.3 years. Cox proportional hazards regression was used to model the association between time to first report of gambling and interaction terms for each of impulsivity and parent education, and impulsivity and area deprivation accounting for sex and ethnicity. FINDINGS Median (interquartile range) age of gambling onset was 17.0 (4.0) years. Impulsivity independently increased the risk of gambling onset among participants with no university-educated parent [hazard ratio (HR) 1.3; 95% confidence interval 1.1-1.5] and those living in highly deprived areas (HR 1.7; 1.5-2.0). Impulsivity was not associated with gambling onset among high SES youth. Among participants with high impulsivity, risks were elevated for those with no university-educated parent relative to one or more university-educated parent (HR 1.7; 1.1-2.7), and for participants living in deprived relative to advantaged areas (HR 5.0; 2.6-9.6). SES was not associated with gambling onset among participants with low impulsivity. CONCLUSIONS Impulsivity is a risk factor for gambling onset among low but not high SES youth, and low SES influences gambling onset primarily among impulsive youth. Gambling prevention programmes may need to consider potential interaction between impulsivity and SES.

Links between casino proximity and gambling participation, expenditure, and pathology.

Two studies investigated the relationship between casino proximity and gambling participation, expenditure, and pathology. In Study 1, 8,842 participants were categorized into 1 of 4 driving distances from their home to the nearest casino in the province of Quebec: 0-100 km, 100.01-200 km, 200.01-300 km, or 300.01-981 km. In Study 2, 5,158 participants, who lived within a 100-km driving distance from the Montreal casino, were classified into 1 of 5 equidistant, 20-km driving distances. A survey company interviewed participants regarding their gambling habits. Results indicated a positive link between casino proximity and gambling participation (at the provincial and Montreal levels) and expenditure (at the provincial level only) but no link with the current prevalence rate of probable pathological gambling or of problem gambling. In a setting in which many types of gambling activities are available, casino proximity in itself does not appear to explain the rate of gambling-related problems. It is necessary to continue prospective research on exposure and adaptation theories as potential explanations for the development of pathological gambling.

Impact of the Format, Arrangement and Availability of Electronic Gaming Machines Outside Casinos on Gambling

Abstract This study evaluates the influence of the format, arrangement and availability of Electronic Gaming Machines Outside Casinos (EGMOC) on gambling behaviour and perceptions. Two studies comprising occasional, at-risk and probable pathological gamblers were conducted. The first study used focus groups, while the second was conducted in a laboratory setting reproducing a bar. The results of the former study indicate that while format does not influence gambling behaviours, the arrangement of EGMOC in a gambling setting is a critical factor: in general, gamblers perceive isolated areas in a gambling venue as a factor contributing to impaired control. However, behavioural results obtained in the laboratory setting do not corroborate subjective data. Finally, gamblers suggested almost unanimously that the availability of EGMOC should be limited to a small number of sites. The results are discussed in the perspective of responsible gambling policies.

Harm Reduction and electronic gambling machines: does this pair make a happy couple or is divorce foreseen?

Recent empirical studies have evaluated if modifying electronic gambling machine (EGM) structural features could encourage safer gambling behaviors and decrease gambling-related problems. Several of these studies refer to Harm Reduction (HR), suggesting that the HR paradigm is useful to design, implement and test the efficacy of various prevention and treatment programs applied to EGM users. After reviewing the origins of HR and specifying its operational definition, this paper discusses the relevance of the HR framework for the study of measures related to EGM use and gambling in general. Examples are given to illustrate the arguments. The results show that HR has been over-inclusive in the field of gambling. A specific and operational definition and application of the HR framework is required for HR to be useful for the advancement of research in the gambling field.

Lay and scientific conceptualizations of impaired control at electronic gambling machines

How do experts in the field of gambling and lay people represent the notion of impaired control (IC) on electronic gambling machines? This study included 37 international experts on gambling, 34 non-pathological gamblers and 32 pathological gamblers. Participation took place in the form of focus groups for gamblers and on the Internet for experts. The mixed methodology of concept mapping was used for comparing the representation of IC by the different groups. It relied on multidimensional scaling and cluster analysis. Qualitative and quantitative analysis revealed an important similarity between experts’ and gamblers’ representation of IC. When respondents were asked about IC, they referred essentially to excessive gambling, irrational cognitions surrounding gambling and negative consequences following excessive gambling. Although considered as central in the conceptualization of problem gambling and often relied upon in clinical practice, IC is not a straightforward and unidimensional concept. Therefore, it needs to be explicitly operationalized and clearly articulated when used in research.

Impact of residential schooling and of child abuse on substance use problem in Indigenous Peoples

Residential schools were the institutions, in operation from the 19th century to the late 20th century, which Indigenous children in Canada were forced to attend. The literature shows that many young people who attended these institutions were victims of neglect and abuse. Negative psychological effects resulting from child abuse have been amply documented. However, very few studies on this subject have been carried out among Canadas Indigenous Peoples. The objective of this study is to evaluate, for an Indigenous population in Quebec (Canada), the impact of residential schooling as well as self-reported experiences of sexual and physical abuse during childhood on the development of alcohol and drug use problems in adulthood. A total of 358 Indigenous participants were interviewed (164 men [45.8%] and 194 women [54.2%]). Alcoholism was evaluated using the Michigan Alcoholism Screening Test (MAST). Drug abuse was assessed with the Drug Abuse Screening Test-20 (DAST). Child abuse and residential schooling were assessed with dichotomous questions (yes/no). Among the participants, 28.5% (n=102) had attended residential schools, 35.2% (n=121) reported having experienced sexual abuse, and 34.1% (n=117) reported having experienced physical abuse before adulthood. Results of the exact logistic regression analyses indicated that residential school attendance was linked to alcohol problems, while child abuse was related to drug use problems. The results of this study highlight the importance of considering the consequences of historical traumas related to residential schools to better understand the current situation of Indigenous Peoples in Canada.

Sexual abuse, residential schooling and probable pathological gambling among Indigenous Peoples

Sexual abuse leads to short-term and long-lasting pervasive outcomes, including addictions. Among Indigenous Peoples, sexual abuse experienced in the context of residential schooling may have led to unresolved grief that is contributing to social problems, such as pathological (disordered) gambling. The aim of this study is to investigate the link between child sexual abuse, residential schooling and probable pathological gambling. The participants were 358 Indigenous persons (54.2% women) aged between 18 and 87 years, from two communities and two semi-urban centers in Quebec (Canada). Probable pathological gambling was evaluated using the South Oaks Gambling Screen (SOGS), and sexual abuse and residential schooling were assessed with dichotomous questions (yes/no). The results indicate an 8.7% past-year prevalence rate of pathological gambling problems among participants, which is high compared with the general Canadian population. Moreover, 35.4% were sexually abused, while 28.1% reported having been schooled in a residential setting. The results of a logistic regression also indicate that experiences of child sexual abuse and residential schooling are associated with probable pathological gambling among Indigenous Peoples. These findings underscore the importance of using an ecological approach when treating gambling, to address childhood traumas alongside current addiction problems.

How important are paper copies of questionnaires? Testing invitations modes when studying social inequalities in smoking among young adults

Using the internet to administer questionnaires for data collection has triggered interest in the past decade of survey research (Israel 2009). In Canada, the general population with access to the internet has grown from 60 % in 2005 to 80 % (Statistics Canada 2011), with young adults following the same trend (Lenhart et al. 2010). However, this trend is not evident across population subgroups as only 54 % of households in the lowest income quartile have access to the internet (Statistics Canada 2011). It is thought that web questionnaire administration can help in countering low response rates and growing research costs, but we were concerned that it should not create socio-economic selection bias problems. Researchers have questioned the influence of invitations that promote access to web versions of questionnaires only, hereby defined as ‘‘Web-only’’ invitations (Kwak and Radler 2002). Indeed, ‘‘Mixed-mode’’ invitations, hereby defined as invitations promoting additional modes of response (paper copy, phone or face-to-face interviews, etc.), have had relative success in increasing response rates (Shih and Fan 2007; Zuidgeest et al. 2011; Van den Berg et al. 2011). With the internet use trends changing rapidly, few recent studies have examined whether response rate and socio-economic status are associated with invitation methods in a population of young adults. In this paper, we report results from a study in which we tested whether adding a paper version of a questionnaire to a mailed invitation (a Mixed-mode invitation) will leads to a sample with different modes of response (i.e. telephone, mail or web), rates of response and socio-demographic characteristics when compared with a Web-only mailed invitation. This study was undertaken within the purview of a larger study entitled the Interdisciplinary Study of Inequalities in Smoking (ISIS), whose goal is to better understand the effects of neighbourhood and individual characteristics in the inequitable socio-economic distribution of smoking across Montreal neighbourhoods.

Social disparities in children's exposure to secondhand smoke in privately owned vehicles

Introduction Secondhand smoke (SHS) can quickly attain high concentrations in cars, posing health risks to passengers and especially to children. This paper assesses whether there are social disparities in childrens exposure to SHS in privately owned vehicles. Methods On weekday mornings and afternoons from September to November 2011, trained observers were stationed at 100 selected street intersections in Montreal, Canada. For each car transporting at least one passenger aged 0–15 years travelling through the intersection, observers recorded the estimated age of the youngest child in the car, whether any occupant was smoking and the licence plate number of the car. Licence plate numbers were linked to an area material deprivation index based on the postal code of the neighbourhood in which the car was registered. Results Smoking was observed in 0.7% of 20 922 cars transporting children. There was an apparent dose–response in the association between area material deprivation level and childrens exposure to SHS in cars. Children travelling in cars registered in the most disadvantaged areas of Montreal were more likely to be exposed to SHS than children travelling in cars registered in the most advantaged areas (unadjusted OR=3.46, 95% CI 1.99 to 6.01). Conclusions This study revealed social disparities in childrens exposure to SHS in privately owned vehicles.

Mapping psychology students’ perspective on group peer-tutoring in statistics

Abstract Students in psychology generally have difficulties to successfully accomplish mandatory courses in statistics. Group peer-tutoring is a pedagogical strategy to support them with a peer that has already successfully mastered the content of such a course. In order to specifically tailor group peer-tutoring to the needs of students and to sustain tutees’ participation, it is important to understand how they conceptualize tutoring. The aim of this study was to provide an empirical investigation of psychology students’ conceptualization regarding cross-year group peer-tutoring in statistics. A multivariate concept mapping analysis generated a relevant three-cluster structure (Tutoring setup, Tutor knowledge, interpersonal skills, and relational dynamics and Student role and commitment to the course) that underlies students’ cognitive structure regarding group peer-tutoring. The implications of the results for selecting and training peer-tutors are discussed.
