Examining DSM-IV Criteria for Pathological Gambling: Psychometric Properties and Evidence from Cognitive Biases

We examined the DSM-IV criteria for pathological gambling as assessed with the DSM-IV-based Diagnostic Interview for Gambling Severity (DIGS; Winters, Specker, & Stinchfield, 2002). We first analyzed the psychometric properties of the DIGS, and then assessed the extent to which performance on two judgment and decision-making tasks, the Georgia Gambling Task (Goodie, 2003) and the Iowa Gambling Task (Bechara, Damasio, Damasio, & Anderson, 1994), related to higher reports of gambling pathology. In a sample of frequent gamblers, we found strong psychometric support for the DSM-IV conception of pathological gambling as measured by the DIGS, predictive relationships between DIGS scores and all cognitive performance measures, and significant differences in performance measures between individuals with and without pathological gambling. Analyses using suggested revisions to the pathological gambling threshold (Stinchfield, 2003) revealed that individuals meeting four of the DSM-IV criteria aligned significantly more with pathological gamblers than with non-pathological gamblers, supporting the suggested change in the cutoff score from five to four symptoms. Discussion focuses on the validity of the DSM-IV criteria as assessed by the DIGS and the role of cognitive biases in pathological gambling.     

Gender Differences among Adolescents with Gambling-Related Problems

Data from five recent studies using self-reports were merged to explore gender differences in the characteristics of adolescent problem gambling, including comorbidity with other youth problems. The sample consisted of 2,750 male and 2,563 female participants. Male problem gamblers were more likely than females to report signs of psychological difficulties while females were more likely to note behavioural problems as a consequence of their gambling problems. Males and females with severe gambling problems had remarkably similar prevalence rates of depression, substance use and weekly gambling. In the non-problem gambling group, depression was more likely to afflict females whereas substance use and frequent gambling were more prevalent among males.     

Does Providing Extended Relapse Prevention Bibliotherapy to Problem Gamblers Improve Outcome?

Relapse rates among pathological gamblers are high with as many as 75% of gamblers returning to gambling shortly after a serious attempt to quit. The present study focused on providing a low cost, easy to access relapse prevention program to such individuals. Based on information collected in our ongoing study of the process of relapse, a series of relapse prevention booklets were developed and evaluated. Individuals who had recently quit gambling (N = 169) were recruited (through media announcements) and randomly assigned to a single mailing condition in which they received one booklet summarizing all of the relapse prevention information or a repeated mailing condition in which they received the summary booklet plus 7 additional booklets mailed to them at regular intervals over the course of a year period. Gambling involvement over the course of the 12-month follow-up period, confirmed by family or friends, was compared between the two groups. Results indicated that participants receiving the repeated mailings were more likely to meet their goal, but they did not differ from participants receiving the single mailing in frequency of gambling or extent of gambling losses. The results of this project suggest that providing extended relapse prevention bibliotherapy to problem gamblers does not improve outcome. However, providing the overview booklet may be a low cost, easy to access alternative for individuals who have quit gambling.     

The role of impulsivity,cognitive bias,and reasoned action in understanding college student gambling

Factors related to gambling behavior among college students in the USA are examined by applying the theory of reasoned action (TRA) and incorporating the concepts of impulsivity and cognitive bias. This study uses a broader approach to analyze gambling behavior by including financial behavior variables using ordinary least squares (OLS) and logistic regressions. The survey data were collected through a self-administered online questionnaire of college students from 19 colleges and universities in the fall of 2010. With a sample of 5024 college students, a majority of the respondents (84.45%) in this study report that they did not gamble in the last 30 days. The results of multivariate analysis indicate that gambling is related to attitudes toward gambling, cognitive bias toward gambling, subjective norms of family members regarding financial behavior, and impulsivity. Underestimation of financial behavior (cognitive bias toward financial behavior) was found to be associated with only gambling frequency but not gambling propensity.     

解构企业利益相关者治理模式

自20世纪80年代后,利益相关者理论在西方兴起并产生了极大反响,被公认为是公司治理理论的一次革命。它克服了"股东至上主义"的单边治理弊端,表达了利益相关者共同治理的理念,为改善公司治理的效率提供了新的视角。基于人力资本和非人力资本博弈角度分析五种利益相关者治理模式,对于改善我国国企治理绩效很有意义。
