What is the latent structure of alcohol use disorders? A taxometric analysis of the Personality Assessment Inventory Alcohol Problems Scale in male and female prison inmates.

Three indicators derived from the Personality Assessment Inventory (PAI) Alcohol Problems scale (ALC)—tolerance/high consumption, loss of control, and negative social and psychological consequences—were subjected to taxometric analysis—mean above minus below a cut (MAMBAC), maximum covariance (MAXCOV), and latent mode factor analysis (L-Mode)—in 1,374 federal prison inmates (905 males, 469 females). Whereas the total sample yielded ambiguous results, the male subsample produced dimensional results, and the female subsample produced taxonic results. Interpreting these findings in light of previous taxometric research on alcohol abuse and dependence it is speculated that while alcohol use disorders may be taxonic in female offenders, they are probably both taxonic and dimensional in male offenders. Two models of male alcohol use disorder in males are considered, one in which the diagnostic features are categorical and the severity of symptomatology is dimensional, and one in which some diagnostic features (e.g., withdrawal) are taxonic and other features (e.g., social problems) are dimensional.

Another missed opportunity? Recognition of alcohol use problems by mental health providers.

Alcohol use problems (AUPs) are prevalent among people seeking psychotherapy. Despite mandates from managed care companies to routinely screen for AUPs, little is known about the screening practices of providers or their ability to identify AUPs based on presenting symptoms. Participants (N = 117) read two case vignettes and suggested initial diagnoses and questions they would ask in order to clarify a diagnosis. Participants were more likely to ask about substance use and diagnose an AUP when the vignette contained explicit reference to the client's substance use as compared to a vignette where the signs of an AUP were more subtle. In both vignettes, a mental health problem was a more likely diagnosis than an AUP. Neither participant attributes nor personal or professional experiences with AUPs reliably shaped responses to the vignettes. The findings are discussed in light of their implications for future research and improved training in addictions for mental health providers.

Stress and alcohol use: A daily process examination of the stressor–vulnerability model.

The authors used a daily diary methodology to examine over 60 days how the within-person associations among event stress, alcohol consumption, and desire to drink varied as a function of gender, positive and negative alcohol-outcome expectancies,' and avoidant coping in a sample of 88 regular drinkers. Multilevel regression analyses indicated that men who more strongly anticipated positive outcomes or a sense of carelessness from drinking drank relatively more on stressful days compared with low-stress days. Similar results were found predicting desire to drink. Men who anticipated greater impairment from drinking drank relatively less on stressful days. In general, these effects did not hold for women. Little evidence was found for the predicted effects for avoidant coping style, and some results showed that avoidant coping style buffered the exacerbating effects of careless unconcern expectancies.

Watching and drinking: Expectancies, prototypes, and friends’ alcohol use mediate the effect of exposure to alcohol use in movies on adolescent drinking.

Objective: To investigate the psychological processes that underlie the relation between exposure to alcohol use in media and adolescent alcohol use. Design: The design consisted of a structural equation modeling analysis of data from four waves of a longitudinal, nationally representative, random-digit dial telephone survey of adolescents in the United States. Main Outcome Measures: The main outcome measures were adolescent alcohol consumption and willingness to use alcohol. Tested mediators were alcohol-related norms, prototypes, expectancies, and friends’ use. Results: Alcohol prototypes, expectancies, willingness, and friends’ use of alcohol (but not perceived prevalence of alcohol use among peers) were significant mediators of the relation between movie alcohol exposure and alcohol consumption, even after controlling for demographic, child, and family factors associated with both movie exposure and alcohol consumption. Conclusion: Established psychological and interpersonal predictors of alcohol use mediate the effects of exposure to alcohol use in movies on adolescent alcohol consumption. The findings suggest that exposure to movie portrayals may operate through similar processes as other social influences, highlighting the importance of considering these exposures in research on adolescent risk behavior.

Are work stressors related to employee substance use? The importance of temporal context assessments of alcohol and illicit drug use.

In this study, the author explored the relations of 2 work stressors (work overload and job insecurity) to employee alcohol use and illicit drug use. The primary goal was to explore the importance of temporal context (before work, during the workday, and after work) in the assessment of substance use compared with context-free (overall) assessments. Data were collected from a national sample of U.S. workers (N = 2,790) who took part in a broad cross-sectional survey on workplace health and safety. Consistent with past research, the results fail to support a relation between work stressors and overall measures of alcohol and illicit drug use. However, the results support the relation of work stressors to alcohol and illicit drug use before work, during the workday, and after work. These results provide support for both the stress-induced substance use and stress response dampening propositions of the tension-reduction hypothesis. When exploring the work environment as a potential cause of employee substance use, these results underscore the importance of measures that assess alcohol and illicit drug use in terms of their temporal relation to the workday.

The role of attachment to family, school, and peers in adolescents’ use of alcohol: A longitudinal study of within-person and between-persons effects.

A great deal of time and money has been spent to understand why adolescents abuse alcohol. Some of the most fruitful work considers the social context navigated by adolescents, including family, school, and peer contexts. However, most of this work focuses on differences between adolescents in these contexts. The present study adds to the literature by considering within-person changes in these contexts and examines the extent to which these changes are related to alcohol use. Significant changes in all 3 contexts were observed, and these changes were significantly related to alcohol use. The significant influence of intrapersonal variability highlights the importance of attending not only to chronic, between-individual issues facing at-risk youths but emergent and transient issues that may temporarily heighten alcohol use risk.

Exaggerated anxiety is not unique to CO? in panic disorder: A comparison of hypercapnic and hypoxic challenges.

Current biological models of panic disorder (PD) assert that this disorder is maintained by hypersensitivity to carbon dioxide (CO?) and related asphyxia cues, which is manifested as an exaggerated suffocation alarm (D. F. Klein, see record 1993-37796-001). Because suffocation can result from both increased CO? (hypercapnia) and decreased oxygen (O?; hypoxia), this study examined respiratory responding and anxiety during 5% CO? (a hypercapnic challenge) and 12% O? (a hypoxic challenge) in 14 PD patients and 14 matched controls (MC). Results demonstrate that irrespective of the source of suffocation, PD patients respond with increased anxiety relative to MC participants. Significant group differences were observed in respiratory functioning, with the PD patients showing higher respiratory rates in response to both challenges. The MC sample demonstrated the expected respiratory responses to both hypercapnia and hypoxia. The findings indicate that PD patients are hypersensitive to alterations in breathing and that this reactivity is not specific to CO?.

How does bilingualism improve executive control? A comparison of active and reactive inhibition mechanisms.

It has been claimed that bilingualism enhances inhibitory control, but the available evidence is equivocal. The authors evaluated several possible versions of the inhibition hypothesis by comparing monolinguals and bilinguals with regard to stop signal performance, inhibition of return, and the attentional blink. These three phenomena, it can be argued, tap into different aspects of inhibition. Monolinguals and bilinguals did not differ in stop signal reaction time and thus were comparable in terms of active-inhibitory efficiency. However, bilinguals showed no facilitation from spatial cues, showed a strong inhibition of return effect, and exhibited a more pronounced attentional blink. These results suggest that bilinguals do not differ from monolinguals in terms of active inhibition but have acquired a better ability to maintain action goals and to use them to bias goal-related information. Under some circumstances, this ability may indirectly lead to more pronounced reactive inhibition of irrelevant information. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Is longing only for Germans? A cross-cultural comparison of Sehnsucht in Germany and the United States.

Sehnsucht, the longing or yearning for ideal yet seemingly unreachable states of life, is a salient topic in German culture and has proven useful for understanding self-regulation across adulthood in a German sample (e.g., Scheibe, Freund, & Baltes, 2007). The current study tested whether findings for German samples could be generalized to the more individualistic and agentic U.S. American culture. Four samples of U.S. American and German participants (total N = 1,276) age 18 to 81 years reported and rated their 2 most important life longings and completed measures of subjective well-being and health. Measurement equivalence was established at the level of factor loadings for central life longing characteristics. German and U.S. American participants did not differ in self-reported ease of identifying personal life longings or their intensity. In comparison to Germans, however, U.S. Americans associated life longings less with utopian, unattainable states and reported less salience of the concept in everyday life. Associations with measures of adaptation suggest that life longings can be both functional and dysfunctional for development in both cultures.

Is acculturation unidimensional or bidimensional? A head-to-head comparison in the prediction of personality, self-identity, and adjustment.

The unidimensional model of acculturation posits that heritage and mainstream culture identifications have a strong inverse relation, whereas the bidimensional model posits that the 2 identifications are independent. The authors compared these models in 3 samples of ethnic Chinese (ns?=?164, 150, and 204), 1 sample of non-Chinese East Asians (n?=?70), and one diverse group of acculturating individuals (n?=?140). Although the unidimensional measure showed a coherent pattern of external correlates, the bidimensional measure revealed independent dimensions corresponding to heritage and mainstream culture identification. These dimensions displayed patterns of noninverse correlations with personality, self-identity, and psychosocial adjustment. The authors conclude that the bidimensional model is a more valid and useful operationalization of acculturation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

What Did and Did Not Cause Collapse of World Trade Center Twin Towers in New York?

Previous analysis of progressive collapse showed that gravity alone suffices to explain the overall collapse of the World Trade Center Towers. However, it remains to be determined whether the recent allegations of controlled demolition have any scientific merit. The present analysis proves that they do not. The video record available for the first few seconds of collapse is shown to agree with the motion history calculated from the differential equation of progressive collapse but, despite uncertain values of some parameters, it is totally out of range of the free fall hypothesis, on which these allegations rest. It is shown that the observed size range (0.01–0.1?mm) of the dust particles of pulverized concrete is consistent with the theory of comminution caused by impact, and that less than 10% of the total gravitational energy, converted to kinetic energy, sufficed to produce this dust (whereas, more than 150?t of TNT per tower would have to be installed, into many small holes drilled into concrete, to produce the same pulverization). The air ejected from the building by gravitational collapse must have attained, near the ground, the speed of almost 500 miles per hour (or 223?m/s, or 803?km/h) on average, and fluctuations must have reached the speed of sound. This explains the loud booms and wide spreading of pulverized concrete and other fragments, and shows that the lower margin of the dust cloud could not have coincided with the crushing front. The resisting upward forces due to pulverization and to ejection of air, dust, and solid fragments, neglected in previous studies, are indeed found to be negligible during the first few seconds of collapse but not insignificant near the end of crush-down. The calculated crush-down duration is found to match a logical interpretation of seismic record, while the free fall duration grossly disagrees with this record.     

Social–cognitive beliefs, alcohol, and tobacco use: A prospective community study of change following a ban on smoking in public places.

Objective: To examine social–cognitive change associated with behavior change after the introduction of a smoke-free public places policy. Design: Adults (N = 583) who use public houses licensed to sell alcohol (pubs) completed questionnaires assessing alcohol and tobacco consumption and social–cognitive beliefs 2 months prior to the introduction of the smoking ban in England on July 1, 2007. Longitudinal follow-up (N = 272) was 3 months after the introduction of the ban. Main outcome measures: Social–cognitive beliefs, daily cigarette consumption, and weekly alcohol consumption. Results: Smokers consumed considerably more alcohol than did nonsmokers at both time points. However, a significant interaction of Smoking Status × Time showed that while smokers had consumed fewer units of alcohol after the ban, nonsmokers showed an increase over the same period. There was a significant reduction in number of cigarettes consumed after the ban. Subjective norms concerning not smoking, and perceived severity of smoking-related illness increased across time. Negative outcomes associated with not smoking were reduced among former smokers and increased across time among smokers. Regression analyses showed that changes in subjective norm and negative outcome expectancies accounted for significant variance in change in smoking across time. Conclusion: Results suggest that the smoking ban may have positive health benefits that are supported by social–cognitive change. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does distraction reduce the alcohol–aggression relation? A cognitive and behavioral test of the attention-allocation model.

Objective: This study provided the first direct test of the cognitive underpinnings of the attention-allocation model and attempted to replicate and extend past behavioral findings for this model as an explanation for alcohol-related aggression. Method: A diverse community sample (55% African American) of men (N = 159) between 21 and 35 years of age (M = 25.80) were randomly assigned to 1 of 2 beverage conditions (i.e., alcohol, no-alcohol control) and 1 of 2 distraction conditions (i.e., distraction, no-distraction). Following beverage consumption, participants were provoked via reception of electric shocks and a verbal insult from a fictitious male opponent. Participants' attention allocation to aggression words (i.e., aggression bias) and physical aggression were measured using a dot probe task and a shock-based aggression task, respectively. Results: Intoxicated men whose attention was distracted displayed significantly lower levels of aggression bias and enacted significantly less physical aggression than intoxicated men whose attention was not distracted. However, aggression bias did not account for the lower levels of alcohol-related aggression in the distraction, relative to the no-distraction, condition. Conclusions: These results replicated and extended past evidence that cognitive distraction is associated with lower levels of alcohol-related aggression in highly provoked males and provide the first known cognitive data to support the attentional processes posited by the attention-allocation model. Discussion focused on how these data inform intervention programming for alcohol-related aggression. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

What makes group MET work? A randomized controlled trial of college student drinkers in mandated alcohol diversion.

Nationally, college drinkers exhibit the highest rates of alcohol consumption and represent the largest percentage of problem drinkers. Group motivational enhancement therapy (GMET) has been found to catalyze problem drinking reductions among college student samples. Although research supporting the use of single-session GMET in college samples (general and mandated) is emergent, no studies have evaluated a comprehensive model of the potential active ingredients of this group intervention. College students (N = 206; 88% White; 63% men; M age = 18.6) mandated to a university alcohol diversion program were randomly assigned to 1 of 3 conditions: the standard-of-care 2-session “Focus on Alcohol Concerns” education group (FAC), a single GMET, or a single alcohol information-only control group (AI) to evaluate the role of 5 putative mediators: readiness to change, self-efficacy, perceived risk, norm estimates, and positive drinking expectancies. At 3- and 6-month follow-ups, GMET students demonstrated greater reductions in problem drinking outcomes (drinks per drinking day, hazardous drinking symptoms, and alcohol-related problems). Of the 5 mediators proposed, only self-efficacy emerged as a significant mediator. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Was Lars sexually assaulted? A study in the reliability of witnesses and of experts.

A 5-year-old boy reported that he had been sexually assaulted by a neighborhood window cleaner. 2 court-appointed "experts" using divergent methods of approach came up with divergent findings. Detailed interviews and the case history are presented in this article and lead to a resolution of the disagreement and a reconstruction of the incident with the conclusion that Lars was not sexually assaulted.
