Interpersonal exposure to danger and risk-taking in the group therapy process]

The writer singles out from the complexities of the group psychotherapeutic process the dynamic pair: inter-personal exposure to danger and the taking of risk. According to his empirical experience and tests the degree of risk-taking is a good parameter for assessing the psychotherapeutic process. For this purpose the inter-action matrix devised by Hill proves itself most useful.     

Group risk-taking and group polarization

There are two aims to this paper; to report in brief preliminary form a number of studies on group risk-taking that have been carried out in Bristol in the past two years, and to relate these studies to an explanation of group risk-taking phenomena primarily in terms of group polarization. The paper has five sections. The first section supplies some background material regarding basic phenomena and previous attempts at explanations. The second section relates to initial individual decisions and the third section to decisions following group discussion and consensus. In the fourth section a tentative explanation of group risk-taking effects is proposed in terms of group polarization processes, together with something like an overall value for risk. Group polarization itself is discussed in terms of normative and informational aspects of social influence. The final section deals with two implications of the proposed explanation, one relating to the role of individual familiarization and the other to the generality of group polarization processes.     

Familiarity and categorization in intergroup behavior

Several studies have shown that social categorization into groups, unaffected by other variables such as own interest, interpersonal relations, conflict of interests, previous hostility, etc., was a sufficient condition to induce discrimination against an outgroup. The purpose of the present study was to test the hypothesis that the subjects' uncertainty and insecurity in a novel situation was, at least in part, responsible for this phenomenon. Two groups of subjects were tested: one group was made familiar with the social and physical setting of the experiment in a situation closely resembling the actual experiment, and came back for a second session in which the actual experiment was conducted; the second group came only for the actual experimental session. The results clearly indicate that, contrary to the hypothesis, the “familiar” group engaged in more out-group discrimination than the “unfamiliar” one. The theoretical and methodological implications of this finding are discussed.     

Alexithymia,verbal intellectual deficit,and neurological dysfunction in relation to risk-taking behavior

This study explored relationships between alexithymia (measured through the Toronto Alexithymia Scale), probable neurological dysfunction (Stroop Color Word Test), and “Verbal” and “Abstraction” IQ scores (Hartford-Shipley Institute for Living Scale) in relation to risk-taking behavior. Subjects were “anti-social” risk-takers (criminal offenders undergoing court-related residential drug treatment), “adventurous” risktakers (college students who regularly engage in such sports as rock-climbing and spelunking), or “normals” (college students who were neither adventurous risk-takers nor criminal offenders). Principal findings reveal that clinically relevant alexithymia is observed among risk-takers of either anti-social or adventurous variety less frequently, but among “normals” more frequently, than chance would predict; that the “verbal deficit pattern” in intellectual functioning is observed more frequently among adventurous risk-takers, less frequently among “normals,” and no more frequently among anti-social risk-takers than chance would predict; and that probable neurological dysfunction is observed more frequently among anti-social risk-takers but less frequently among adventurous risk-takers or “normals” than chance would predict. Results support only in part the Pallone-Hennessy (1999) conceptual model of the genesis and correlates of risk-taking in respect of anti-social, but not in respect of adventurous risk-takers. This study was supported by grants from the Henry Rutgers Scholars Program, Rutgers College, and the Fund for Correctional Psychology, Center of Alcohol Studies.

Comparing personality constructs of risk-taking behavior

Canadian subjects (N = 120) completed four psychological scales. Three of the scales were directly related to risk-taking behavior. These were the Sensation Seeking Scale (SSS V; Zuckerman, 1979), the Tension Risk Adventure Inventory (TRAI; Keinan et al., 1984) and the Telic Dominance Scale (TDS; Murgatroyd et al., 1978). In addition, subjects completed the Desire for Control Scale (DCS; Burger and Cooper, 1979) to investigate the role of desire for control in risk-taking. The results indicated (1) significant differences between age and sensation seeking (2) a four-factor structure for the TRAI following factor analysis with this Canadian sample (3) numerous intra- and inter-scale relationships obtained from correlation analyses of and (4) four major dimensions arising from PCA of the four inventory scales.

The impact of school connectedness on violent behavior, transport risk-taking behavior, and associated injuries in adolescence

Adolescents engage in many risk-taking behaviors that have the potential to lead to injury. The school environment has a significant role in shaping adolescent behavior, and this study aimed to provide additional information about the benefits associated with connectedness to school. Early adolescents aged 13 to 15 years (N = 509, 49% boys) were surveyed about school connectedness, engagement in transport and violence risk-taking, and injury experiences. Significant relations were found between school connectedness and reduced engagement in both transport and violence risk-taking, as well as fewer associated injuries. This study has implications for the area of risk-taking and injury prevention, as it suggests the potential for reducing adolescents' injury through school based interventions targeting school connectedness.     

Gambling behavior and gambling problems in Norway 2007

In Norway, legalized gambling is pervasive, easily accessible and socially accepted, particularly the participation in national lotteries. We conducted a stratified probability sample study during January–March 2007 (age group 16–74 years, N  = 3,482, response rate 36.1%) to assess gambling behavior and prevalence of problematic gambling by the NORC Diagnostic Screen (NODS). Overall, 67.9% of the study population had been engaged in past-year gambling and 0.7% were past-year problematic gamblers (NODS score 3+). Male gender, low educational level, single marital status, and being born in a non-Western country were variables positively associated with problematic gambling. Past-year problematic gamblers indicated the slot machine (34.6%) and Internet gambling (26.9%) as the most important games, while most non-problematic gamblers pointed out the lotteries (62.3%) as the most important game. The prevalence of self-reported sleeping disorders, depression and other psychological impairments was significantly higher among problematic gamblers. Gambling problems affect people's lives in multiple ways.     

Measurement and structure of pathological gambling behavior

The serious effects of pathological gambling on both gamblers and their families warrants research on the disorder. This study aimed at identifying components of pathological gambling with the goal of developing methods for early detection and preventive strategies. A factor analysis of behaviors hypothesized to relate to pathological gambling resulted in a multidimensional model of the disorder. Eight factors were identified, including distinct neurotic, psychopathic, and impulsive components, and used in a comparative analysis of 83 admitted compulsive gamblers and 61 nongamblers. Five of the factors differentiated the two groups even when sex, age, and education were controlled. Implications of these findings are discussed.     

Internet gambling, substance use, and delinquent behavior: an adolescent deviant behavior involvement pattern

Internet gambling among adolescents is a growing phenomenon that has received little attention to date. This study examines associations between Internet gambling and the severity of gambling, substance use (SU), and delinquent behavior among 1,870 Quebec students aged 14 to 18. The results show a higher proportion of Internet-gambling (IG) students reporting problematic substance use and delinquency, compared with nongamblers (NG) and non-Internet gamblers (NIG). Furthermore, a higher proportion of at-risk and probable pathological gamblers are found among IG compared with NIG. A moderating effect (Baron & Kenny, 1986) of the gambler categories (NIG, IG) was found in the relationship between the associated problems and the severity of gambling. Among IG, the severity of delinquency and of substance use contributes to explaining gambling severity whereas, among NIG, the severity of delinquency is the only factor that significantly contributes to such an explanation. Discussion of the results is based on Jessor, Donovan, and Costa's (1991) general deviance syndrome theory.     

Modeling behavior in a clinically diagnostic sequential risk-taking task

This article models the cognitive processes underlying learning and sequential choice in a risk-taking task for the purposes of understanding how they occur in this moderately complex environment and how behavior in it relates to self-reported real-world risk taking. The best stochastic model assumes that participants incorrectly treat outcome probabilities as stationary, update probabilities in a Bayesian fashion, evaluate choice policies prior to rather than during responding, and maintain constant response sensitivity. The model parameter associated with subjective value of gains correlates well with external risk taking. Both the overall approach, which can be expanded as the basic paradigm is varied, and the specific results provide direction for theories of risky choice and for understanding risk taking as a public health problem.     

Factors influencing adolescents' decisions to engage in risk-taking behavior

Few studies have assessed adolescent risk-taking from a decision-making perspective while also looking at sensation-seeking and locus of control. In this study, 171 older adolescents completed a risk-taking inventory to measure risk involvement. Sensation-seeking and locus of control, as well as perceived benefits and costs, were assessed to determine their effects on risk-taking. Results showed that perceived risks affected risk-taking more significantly than did perceived benefits. Higher sensation-seeking tendencies were affiliated with more risk-taking. Locus of control was not related to risk-taking.     

Bulimia nervosa: group behavior therapy with exposure plus response prevention

Exposure plus response prevention has been demonstrated to be effective in the treatment of bulimia nervosa. However, when done individually, it is labor intensive and cost-ineffective. In the present study exposure plus response prevention was used in the context of a 6-wk., 12-session behavioral group. In addition to the exposure plus response-prevention component, other techniques included self-monitoring, cognitive restructuring, eating-habit stabilization and problem-solving. Eight bulimic women, vomiting a minimum of five times per week for at least a year, participated in the group. At the end of treatment significant reductions in bingeing and vomiting behaviors were reported by all but one subject, substantiated by significantly lower depression scores (Beck Depression Inventory) and binge-eating scores (Binge Eating Scale). At 6 mo. and 1 yr. posttreatment, 6 of 8 subjects reported averaging less than one binge-purge episode per week, one subject continued unchanged, and one subject had relapsed. A group of wait-list control subjects reported essentially no change in binge-purge frequency over the treatment period. Exposure plus response prevention conducted in a behavioral group context appears to be a cost-effective alternative to individual treatment.     

Remembering, Familiarity, and Source Monitoring

Two experiments investigated recollective experience in a source monitoring task. Subjects saw an array of objects and performed, watched, or imagined actions involving pairs of objects. In a subsequent recognition test, subjects indicated whether their recognition judgements were made on the basis of conscious recollective experience (“remember” responses), or on some other basis such as familiarity (“know” responses). The proportions of correct “remember” responses for both objects and actions decreased from performed, through watched, to imagined actions, whereas the proportions of correct “know” responses were uninfluenced by the source of the memories. In addition, the relationship between recollective experience and accuracy of source judgement varied across sources. Source accuracy for performed actions was obtained only in “remember” responses, whereas source accuracy for imagined actions was obtained only in “know” responses. Source accuracy for watched actions was obtained in both “remember” and “know” responses. The findings suggest that the types of memory attributes available at retrieval determine the quality of subsequent memory experience, and it is proposed that memories with strongly self-referential attributes (arising from performed actions) powerfully cue recollective experience during retrieval.     

‘Chasing' in gambling behavior: personality and cognitive determinants

The phenomenon of ‘chasing' has been identified as one of the central characteristics of the behavior of pathological gamblers [American Psychiatric Association (1994). Diagnostic and statistical manual of mental disorders (4th ed., DSM IV). Washington, DC: APA]. It consists of more frequent involvement, increased persistence and elevated monetary risk in an effort to recoup money that has been lost. The present research makes a distinction between within- and between-session chasing, and attempts to examine the determinants of within-session chasing in a reasonably valid laboratory analogue. Male college students who gambled (N=248) were given US$10 and an opportunity to gamble. They could: (1) decline to gamble and keep their US$10 (nonplayers); (2) gamble and win even more money by quitting at a more optimal time (nonchasers); or (3) gamble longer than they should, resulting in the loss of all available money (chasers). Zuckerman's impulsivity factor (from the ZKPQ) discriminated chasers from nonchasers. Breen and Zuckerman's Gambling Beliefs and Attitudes Survey (GABS) discriminated players from nonplayers. A sensation-seeking explanation of within-session chasing was not supported. The results are discussed in terms of the impact of impulsivity on within-session chasing. It is suggested that the GABS may serve as a general measure of ‘affinity' to gambling, and could be useful in examining the process of between-session chasing, that is, returning on another day to ‘get even'.
