Shared predictors of youthful gambling, substance use, and delinquency.

Given that gambling, alcohol misuse, other drug use, and delinquency are correlated, it is hypothesized that these problem behaviors have shared antecedents. Measures from 3 explanatory domains--sociodemographic factors (age, race, and socioeconomic status), individual factors (impulsivity and moral disengagement), and socialization factors (parental monitoring and peer delinquency)--were tested for links to problem behaviors in 2 longitudinal samples of adolescents. Black youth had lower levels of problem behaviors than Whites. Impulsivity was a significant predictor of alcohol misuse for females and delinquency for males. Moral disengagement predicted gambling for males. Parental monitoring showed a significant inverse relationship to alcohol misuse and other substance use for males. Peer delinquency showed numerous prospective paths to youth problem behaviors for both genders.

Substance involvement and the trajectory of criminal offending in young male.

The current study investigated the influence of substance involvement on the trajectory of delinquency. Data were from 625 Buffalo, NY males aged 16-19, interviewed three times at 18-month intervals. Hierarchical linear models were fit separately for respondents with increasing and declining delinquency. In the increasing group, aIcohol involvment was associated with a higher starting point (intercept), and alcohol dependence and drug consequences were associated with a faster increase. In the declining group, alcohol dependence and drug consequences were associated with a higher starting point, and frequency of drug use was associated with a slower decline. Alcohol involvement is important in the early delinquent career whereas illicit drug use delays maturing out of delinquency. In a further analysis, substance involvement variables were time-varying covariates in the within-subjects model and controls in the between-subjects model. Respondents' alcohol and other drug use varied across time in sync with their criminal offending.

The relationship of ecological and geographic factors to gambling behavior and pathology.

The current study examined the effect of neighborhood disadvantage and gambling availability on gambling participation and pathology. A national telephone survey included 2631 US adults. Census data was used to characterize the respondent's neighborhood, and the distance from the respondent's home to gambling facilities was calculated. Logistic and linear regressions were performed to predict gambling participation and pathology. Results showed that the neighborhood disadvantage was positively related to frequency of gambling and problem/pathological gambling. The presence of a casino within 10 miles of the respondent's home was positively related to problem/pathological gambling. The permissiveness of gambling laws was positively related to any gambling in the past year, as well as frequent gambling. These results were interpreted to mean that the ecology of disadvantaged neighborhoods promotes gambling pathology, and that availability of gambling opportunities promotes gambling participation and pathology.

Risk factors for pathological gambling.

To better understand pathological gambling, potential risk factors were assessed within three domains--gambling behaviors, substance abuse and other problem behaviors, and sociodemographic factors. A random-digit-dial telephone survey was conducted in 1999-2000 with a representative sample of the U.S. population aged 18 or older. The current analyses uses data from the 2168 respondents who gambled in the year before the interview. Gambling measures included the Diagnostic Interview Schedule (DIS)-IV for pathological gambling, frequency of 15 types of gambling, and size of win or loss on the last occasion. Other measures included the quantity and frequency of alcohol consumption, frequency of illicit drug use and criminal offending, and the DIS-IV for alcohol and drug abuse and dependence. Results showed that casino gambling is associated with a high risk of gambling pathology. Lottery, cards, and bingo are associated with a moderately high risk of gambling pathology. Participation in a greater number of types of gambling is strongly predictive of gambling pathology, even after frequency of gambling and size of win or loss are taken into account. Alcohol abuse is strongly predictive of gambling pathology, even with gambling behaviors held constant. Minority and low socioeconomic status (SES) group members have higher levels of gambling pathology than other groups after all other factors are considered.

Gambling participation and pathology in the United States--a sociodemographic analysis using classification trees.

This article describes an analysis of gambling and gambling pathology from a telephone survey of 2631 U.S. residents, using Chi-square Automatic Interaction Detector (CHAID). Catholics were more likely to have gambled (92%) than Protestants (78%), and elderly Protestants were the least likely (55%) group to have gambled. Among past-year gamblers, men gambled more often (74 times) than women (46 times). The most frequent gamblers were divorced, widowed, or cohabiting men (125 times). Minorities were much more likely than whites to be problem gamblers (PGs). Nonpoor, married, or widowed whites were the least likely to be PGs.

Simultaneous drinking and gambling: a risk factor for pathological gambling.

The aim of the current study was to determine the effect of simultaneous drinking and gambling on negative consequences from gambling. Data was analyzed from a national telephone survey of 2631 US residents aged 18 or older. Males were more likely than females to drink while gambling. Simultaneous drinking and gambling was more closely associated with video keno, pull tabs, dice (not in a casino) and casino gambling than with other types of gambling. Those who drank while gambling were more likely to be problem gamblers, even when holding constant frequency of gambling, size of the average win or loss, and average alcohol consumption. Those gamblers who are drinkers, but did not drink while gambling, had a prevalence of problem gambling of close to zero. They had a lower prevalence of problem gambling than gamblers who didn't drink alcohol at all in the past year, and a much lower prevalence than those who drank while gambling. These results were interpreted to mean that simultaneous drinking and gambling is an indicator of a more reckless gambler. The results did not support the theory that gambling while under the influence of alcohol causes more risky gambling behavior.

The association of irritability and impulsivity with suicidal ideation among 15- to 20-year-old males.

Information on the association of impulsivity and measures of aggression with suicidal ideation in adolescents and young adults is limited. Data were gathered from a community sample of 625 adolescent and young adult males. Analyses were based on multivariate generalized estimating equations. Impulsivity and irritability were associated strongly with suicidal ideation after accounting for alcohol dependence and other aggression-related constructs including psychopathy. Given that irritable, impulsive adolescent males appear to contemplate suicidal behavior, their heightened suicide risk may be anticipated and mitigated.

Gambling participation in the U.S.--results from a national survey.

Demographic patterns of gambling participation in the U.S. were examined. A national telephone survey was conducted with 2,630 representative U.S. residents aged 18 or older. The sample as weighted for analysis was 48% male, 12% black, and 11% Hispanic. Respondents were questioned on 15 types of gambling: how often they played and how much they won or lost. Eighty-two percent gambled in the past year. Lottery was the most commonly played game, while casino gambling accounted for the largest extent of gambling involvement. Men and women were equally likely to gamble in the past year, but men gambled more frequently and had larger wins and losses, particularly on sports betting and games of skill. Blacks were less likely to have gambled in the past year, but blacks who gambled did so more heavily than other racial groups. Blacks and Hispanics were more likely than average to be pathological gamblers. The rate of past year gambling declined with age, but extent of gambling involvement among gamblers did not vary with age. Rates of participation in most forms of gambling increased with socioeconomic status, but higher socioeconomic status gamblers had lower rates of pathological gambling, and lower extent of gambling involvement, particularly for lottery. New Englanders gambled more heavily than other Americans. Comparison with past studies showed an increase in overall gambling participation in the U.S., and large increases in rates of participation in lottery and casino gambling.

The role of aggression-related alcohol expectancies in explaining the link between alcohol and violent behavior.

Studies have demonstrated an acute effect of alcohol on violent behavior. A remaining issue is the motivation of some offenders for using alcohol before offending. A common explanation is based on the relationship between daily drinking habit and drinking before offending. Drawing upon the deviance disavowal assumption, the embolden hypothesis, and expectancy theories, the present study argues that alcohol may be used intentionally to promote or excuse the violent consequences of drinking. Using data from the 1993 Buffalo Longitudinal Study of Young Men, the present study examines the independent effect of aggression-related alcohol expectancies on drinking before offending and the interactive effect of aggression-related alcohol expectancies and daily alcohol consumption on drinking before offending. The results indicate a significant effect of aggression-related alcohol expectancies on alcohol use before offending. This supports the argument that drinking may be a means for carrying out violent acts. A significant interactive effect was found between aggression-related alcohol expectancies and daily alcohol consumption. "Heavy" daily alcohol consumption increased the likelihood of drinking before offending for individuals who had high aggression-related alcohol expectancies more than those who had low such expectancies. Aggression-related alcohol expectancies moderated the effect of daily drinking on drinking before offending. The implications of these findings are discussed for the link between alcohol and violence.

Effects of alcohol misuse on gambling patterns in youth.

OBJECTIVE: Gambling and alcohol misuse are prevalent among youth and may be part of a common problem behavior syndrome. It was hypothesized that alcohol misuse would predict a pattern of increased youth gambling or a pattern of stable high gambling after controlling for key sociodemographic, socialization and individual factors. METHOD: Data were analyzed from two longitudinal studies of youth living in a western New York metropolitan area. Respondents' gambling at two times over the course of 12-18 months was classified into one of five gambling pattern groups, representing flat-low, increasing, flat-medium, flat-high and decreasing levels of gambling. RESULTS: Alcohol misuse among males predicted increasing gambling over time or a pattern of stability of high rates of gambling even after controlling for socioeconomic status, race, age, impulsivity and parental monitoring in the family study. Higher parental monitoring and lower alcohol misuse were significant in predicting a decreasing pattern of gambling among males in the male delinquency study. For females in the family study, alcohol misuse predicted an increasing pattern of gambling only when other factors such as high impulsivity or low parental monitoring were present. CONCLUSIONS: An understanding of adolescent gambling must take into account a variety of demographic, socialization and individual factors, as well as the co-occurrence of alcohol misuse.
