The role of head injury in cognitive functioning, emotional adjustment and criminal behaviour

In two investigations, 50% of non-violent convicted felons, who avoided incarceration by participating in a day reporting programme, reported a prior history of head injury and current problems in cognitive and emotional functioning. Only 5% of a college sample in the first investigation and 15% of a community sample in the second investigation reported prior head injury. In a third investigation, 83% of felons who had reported a history of head injury also reported a date for their head injury that preceded the date of their first encounter with law enforcement. Some participants reported no trouble with the law until after experiencing a head injury that occurred in their late thirties. Considering the research reported here and elsewhere in the literature, it appears that many serious crimes follow a head injury. One implication of the findings reported here is that many crimes might not occur if people with head injury were given prompt and comprehensive treatment after the injury.

Measuring college students' motives for playing drinking games.

Students may choose to play drinking games not only for reasons related to alcohol consumption but also because of incentives related to other aspects of play (competition, fun, interpersonal dominance, etc.). College students (120 men and 167 women) completed measures of motives for playing (based on T. J. Johnson, S. Hamilton, & V. L. Sheets, 1999) and consequences of playing drinking games. Exploratory principal-components analysis identified 8 reasons for playing. Men and women differed in their endorsement of the factors. Motives for play directly predicted consequences of play independently of alcohol consumption. Specific motives predicted specific types of consequences. In multiple regression analyses, Conformity motives were negatively related to consequences and may represent a form of protective motive.

Sensation seeking and drinking game participation in heavy-drinking college students

Previous research has identified differences between heavy-drinking students who play drinking games and those who do not. Johnson, Wendel, and Hamilton (1998) suggested that heavy-drinking players may correspond to Cloningers (1987) Type II alcoholic and that heavy-drinking nonplayers resemble Type I. The current study predicted that (a) sensation seeking would be associated with greater frequency of play and greater frequency of negative consequences from play and that (b) heavy-drinking students who play drinking games would be higher in sensation seeking than heavy-drinking students who do not play. A sample of 172 female and 84 male college students completed the Sensation Seeking Scale Form V, questions about quantity and frequency of alcohol consumption, and questions regarding drinking game participation. Higher levels of sensation seeking predicted greater frequency of play even after controlling for overall quantity and frequency of consumption. Sensation seeking was also related to specific motives for play. Men who were higher in sensation seeking experienced more negative alcohol-related consequences as a result of play. In women, but not in men. heavy-drinking players were higher in sensation seeking than heavy-nondrinking nonplayers. The results of the current study do not clearly support Cloningers model, but they are consistent with other research concerning the role of sensation seeking and risk taking in contributing to negative alcohol-related consequences. Personality style likely interacts with social norms and contextual factors in influencing drinking game participation and consequences of play.

Social anxiety, alcohol expectancies, and drinking-game participation

Few studies have investigated factors contributing to college student participation in drinking games. The extent to which drinking games contribute to negative alcohol-related consequences is uncertain. The current study attempted to (a) clarify the risks posed by drinking-game participation, (b) identify characteristics of heavy drinkers who play frequently and those who seldom play, and (c) determine if students participated in drinking games to reduce anxiety in social situations. Tension reduction alcohol expectancies were examined as a potential moderator variable for the relationship between social anxiety and frequency of play. Drinking games accounted for high proportions of all negative alcohol-related consequences and appeared to be strongly associated with instances of sexual victimization. Contrary to predictions based on the tension reduction hypothesis, greater frequency of play was associated with lower social anxiety, and no moderating effect was found for tension reduction expectancies. Frequent players also had more environmental exposure to drinking games. In men, heavy-drinking players may resemble Clonningers Type 1 alcoholic, whereas heavy-drinking nonplayers resemble the Type 2 pattern. A full understanding of college student drinking behavior may not be possible without greater understanding of drinking games.

College students' self-reported reasons for playing drinking games.

Two samples of college students who engage in drinking games completed questions about their drinking behavior, a set of items concerning their reasons for playing drinking games, and various self-report measures of personality. Principal components analysis using the first sample yielded four factors: Relaxation & Disinhibition, Fun & Celebration, Conformity, and Sexual Manipulation. A similar factor structure was also obtained in the second sample. In both samples, Fun & Celebration and Sexual Manipulation reasons were most strongly predictive of frequency of play and quantity of alcohol consumed while playing. In men, Sexual Manipulation reasons for play predicted frequency of taking sexual advantage of others during play. Endorsement of Conformity and Relaxation & Disinhibition reasons were associated with high social anxiety and low assertiveness. Reasons for play predicted consumption, both in drinking-game situations and overall, even after removing variance due to general reasons for drinking. Psychometric properties of the current measure are less than ideal, but the constructs identified appear to have important implications for prevention. Assessment of self-reported reasons for drinking in specific situations may be a generally useful strategy.

College students' reasons for not drinking and not playing drinking games.

Few studies have examined college students’ reasons for not drinking, and no studies have addressed their reasons for not playing drinking games. This study developed measures of both constructs using a sample of 147 college students. Principal components analysis identified six Reasons for Not Drinking factors and five Reasons for Not Playing Drinking Games factors. Internal consistency and intercorrelations of the factors were examined. The factors correlated in theoretically meaningful directions with measures of alcohol consumption, alcohol outcome expectancies, reasons for drinking, self-esteem, and personality. Research findings are discussed in regards to their relevance to prevention and treatment strategies among the college population.

Empirical Identification of Dimensions of Religiousness and Spirituality

Numerous measures of Religiousness and Spirituality (R/S) exist, but the number and type of dimensions represented by these measures remain unclear. We used exploratory and confirmatory analyses in two U.S. college-student samples to identify five dimensions of R/S: Religious/Spiritual Involvement, Search for Meaning, Religious Struggle, Quest, and Spiritual Well-Being. Over half of the measures loaded on the first factor (Religious/Spiritual Involvement). In bivariate and multivariate analyses, the factors had unique patterns of relationships with each other, with alcohol use and problems, and with measures of affect and personality. Although this study utilized a college-student sample, the factors obtained are similar to those found in studies using other samples. While R/S can be represented as a global characteristic, additional dimensions also exist and may have significance for understanding how R/S are related to health and well-being.

College students' self-reported reasons for why drinking games end☆

Previous research has noted that drinking game participation is associated with increased risk of negative alcohol-related consequences. The current study examined the reasons that students give for how drinking games end and/or why students elect to quit playing. Both men and women identified other people quitting and deciding that they have had enough to drink as the most important single item reasons for quitting play. Principal components analysis using a list of 20 reasons identified six factors, four of which contained overlapping items: Conformity/Boredom; Interpersonal Competition; Sexual Contact; Excessive Consumption; Interpersonal Conflict; and External Circumstances. The factors correlated in a theoretically meaningful fashion with measures of alcohol consumption and consequences and personality. Conformity/Boredom reasons and External Circumstances reasons were least associated with negative alcohol-related consequences. Many students apparently play until they get too drunk or too sick to continue. Understanding how games end may offer clues to designing skills training or other prevention interventions to reduce harm associated with drinking games.

Mediators of the relationship between religiousness/spirituality and alcohol problems in an adult community sample

Johnson et al. (2008b) reported that, in a college student sample, the effect of religiousness on alcohol use was mediated by negative beliefs about alcohol, social influences, and spiritual well-being, and that these variables in turn impacted alcohol use and problems both directly and indirectly via motives for drinking. This study attempted to replicate those findings in a sample of community dwelling adults (N=211). The effect of Religious/Spiritual Involvement was mediated by Negative Beliefs about Alcohol, Social Modeling, and Spiritual-Well-Being. However, Social Modeling had stronger relationships with motives for drinking and alcohol consumption than the other two mediators. The effect of Religious Struggle on Alcohol Problems was mediated by Spiritual Well-Being and coping motives for drinking. Results provide further support for the motivational model of alcohol use and suggest plausible mechanisms by which religiousness could causally impact alcohol use and problems. Religious struggle may be a clinically significant correlate of alcohol problems.

Issues in Measuring Spirituality and Religiousness in Alcohol Research

There is at present no consensus in the field on definitions of spirituality and religiousness (SR). We will not attempt to present single,...
