Hangover sensitivity after controlled alcohol administration as predictor of post-college drinking

Predicting continued problematic levels of drinking after the early 20's could help with early identification of persons at risk. This study investigated whether hangover insensitivity could predict postcollege drinking and problems beyond the variance due to drinking patterns. In a preliminary study, 134 college seniors from a laboratory study of hangover (Time 1) were contacted and assessed 1-4 years (M = 2.3) later (Time 2). Hangover severity was studied after controlled alcohol administration to a specific dose while controlling sleep and environmental influences. Hangover severity at Time 1 was used to predict Time 2 drinking volume and problems while controlling for relevant demographics and Time 1 drinking volume. Hangover insensitivity at Time 1 tended to predict a clinical level of alcohol problems with a large statistical effect size. Hangover sensitivity also correlated positively with sensitivity to alcohol intoxication. Hangover severity did not predict future drinking volume. Hangover insensitivity correlates with insensitivity to intoxication and might predict more serious alcohol problems in the future, suggesting that a future larger study is warranted. Hangover insensitivity could result from physiological factors underlying low sensitivity to alcohol or risk for alcoholism.     

Daily fluctuations in perfectionism dimensions and their relation to eating disorder symptoms

Multidimensional perfectionism has been shown to play an important role in eating disorders (EDs). However, research examining this relation has primarily focused on relatively stable inter-individual differences between persons, thereby failing to examine how these variables are associated within individuals on a daily basis. This study examines how daily fluctuations in Personal Standards (PS) perfectionism and Evaluative Concerns (EC) perfectionism relate to each other and to fluctuations in ED symptoms. Adolescents (N = 275) completed questionnaires each evening during seven consecutive days. Multilevel modeling showed significant day-to-day fluctuations in PS and EC perfectionism, and showed that both dimensions are intertwined in the day. Among females, fluctuations in EC perfectionism co-varied with fluctuations in ED symptoms.     

Sex differences in components of imagined perspective transformation

We explored the impact of motor experience on the interaction between implicit motor simulation and language-processing. In an action familiarity judgment task, expert volleyball players, fans and novices were presented with semantically correct sentences describing possible and not possible motor actions, all as negative or positive contexts, e.g., "Don't shank!" or "Assist!". As processing negated action-phrases is known to reduce simulation states, exposure to negative or positive contexts was used here to test how simulation varies according to motor feasibility (possible, impossible) and experience (experts and fans). A significant group×stimulus×context interaction showed that athletes and fans, took longer to process negative than positive contexts for possible actions, compared to action-impossible sentences. In addition, experts were significantly faster and more accurate than fans and, in turn, they were both more accurate than novices. Thus, implicit motor simulation impacts on action-verb processing depending on (i) the domain-relevant expertise, (ii) the feasibility of the actions, and (iii) on whether scenes are presented in a negated context. These results suggest that the implicit triggering of motor representations is modulated by the context and it is tuned to people's motor repertoire, even when actions are described linguistically.     

Operationalizing the Assessment and Management of Violence Risk in the Short-term

Assessing risk of violence in the short term is crucial for managing and preventing violence, especially in institutions such as psychiatric units and prisons. Despite a lack of consensus on the definition of "short term", a number of recent tools and guidelines have been developed to aid short-term clinical decision-making. Whereas the supporting evidence for the new tools is impressive, limitations remain in terms of the focus on prediction, limited consideration of strengths, and poor integration with formulation and risk management. The Short-Term Assessment of Risk and Treatability (START) is a brief clinical guide for the dynamic assessment of risks, strengths and treatability. It focuses on short-term risks and the characteristics of the individual that, if changed, might lead to an increase or decrease in risk. The START has the potential to operationalize the structured professional judgment (SPJ) approach in order to inform the evaluation of multiple risk domains relevant to everyday psychiatric clinical practice. However, explicit guidance on integrating risk assessment, formulation and management is limited in the START and this paper describes the SPJ approach, reviews recent developments in approaches to risk, and considers how the START can be used to inform SPJ approaches and link risk assessment, formulation, and management.

Iona College Community Centered Family Health History Project: Lessons Learned from Student Focus Groups

The Community Centered Family Health History project was initiated to create accessible family health history tools produced by and for the community. The project goal was to promote increased community engagement in health education by encouraging conversations among family members that would translate knowledge of family health history into healthy lifestyle choices. As one of seven community partners, Iona College participated in customizing and beta-testing the Does It Run in the Family? toolkit. Twenty-nine college students were engaged to recruit three relatives related by blood to provide feedback on the utility of the toolkit. The toolkit consists of two booklets—“A Guide to Family Health History” and “A Guide to Understanding Genetics and Health”—explaining the importance of knowing and talking about health within the family as well as basics about how conditions are passed down through generations. Twenty-two of the twenty-nine students participated in focus groups to discuss their reactions to participation in the project. Students in the focus group reported that the study participants—students and their family members—found the toolkit to be user friendly and the experience a valuable one that prompted many to take positive steps toward good health.     

Dyadic Coping Among Couples with COPD: A Pilot Study

COPD (chronic obstructive pulmonary disease) is associated with psychological distress for patients as well as their partners. Dyadic coping can be negatively impacted by stressors. This study's objective was to compare the dyadic coping of couples in which one partner suffered from COPD with healthy couples of the same age. A total of 43 complete couples with COPD and 138 healthy couples participated in this pilot study. The surveys were sent by mail. The response rate of the COPD sample was 24.3%. In order to analyze the effect of gender and role (patient vs. partner) on dyadic coping, linear mixed models were calculated. To analyze the effect of gender and group (COPD group vs. normative comparison group) on dyadic coping, two-way analyses of variance were calculated for independent samples. COPD patients and their partners indicated that the patients received more support and were less able to provide support to their partners. This difference was also evident in comparison with the normative comparison group. In addition, couples with COPD perceived higher levels of negative coping and provided a considerably lower assessment of their positive dyadic coping. The dyadic coping of couples with COPD is unbalanced and more negative when compared to that of healthy couples. Interventions aimed at supporting COPD couples should seek to improve couples' dyadic coping in addition to individual coping strategies.     

Caffeine enhances real-world language processing: evidence from a proofreading task

Caffeine has become the most prevalently consumed psychostimulant in the world, but its influences on daily real-world functioning are relatively unknown. The present work investigated the effects of caffeine (0 mg, 100 mg, 200 mg, 400 mg) on a commonplace language task that required readers to identify and correct 4 error types in extended discourse: simple local errors (misspelling 1- to 2-syllable words), complex local errors (misspelling 3- to 5-syllable words), simple global errors (incorrect homophones), and complex global errors (incorrect subject-verb agreement and verb tense). In 2 placebo-controlled, double-blind studies using repeated-measures designs, we found higher detection and repair rates for complex global errors, asymptoting at 200 mg in low consumers (Experiment 1) and peaking at 400 mg in high consumers (Experiment 2). In both cases, covariate analyses demonstrated that arousal state mediated the relationship between caffeine consumption and the detection and repair of complex global errors. Detection and repair rates for the other 3 error types were not affected by caffeine consumption. Taken together, we demonstrate that caffeine has differential effects on error detection and repair as a function of dose and error type, and this relationship is closely tied to caffeine's effects on subjective arousal state. These results support the notion that central nervous system stimulants may enhance global processing of language-based materials and suggest that such effects may originate in caffeine-related right hemisphere brain processes. Implications for understanding the relationships between caffeine consumption and real-world cognitive functioning are discussed.     

Subtyping children and adolescents who are overweight based on eating pathology and psychopathology

Children and adolescents who are overweight can differ on dimensions measuring dietary restraint and psychopathology. Classifying clinical obese children and adolescents based on these psychological characteristics is shown to be useful in making differential prognoses. The present study aimed to research the validity of subtyping children and adolescents with overweight (N?=?138) in a non-clinical sample. Using cluster analysis, results revealed three subtypes: a dietary restraint/internalizing group (DR?+?IN; n?=?41), a pure internalizing group (IN; n?=?20) and a non-symptomatic group (NS; n?=?77). The DR?+?IN group outscored both other groups on measures of eating pathology, whereas the IN group outscored both other groups on measures of negative offect. Interestingly, the three groups did not differ on degree of overweight. The results seem to suggest that different psychological mechanisms can be observed in subgroups of young overweight adolescents. Further research should explore how individual psychological characteristics can be helpful when stipulating weight loss treatment programmes.     

The effect of age on decision making according to the Iowa gambling task

Aging has been associated with several brain changes that often affect the cognitive functioning of adults, but changes in executive functions, particularly in the field of decision making, have not been fully investigated. The Iowa Gambling Task (IGT) is a widely used tool to evaluate decision making, but little is known about the effect of age on its results. This study used the IGT and compared healthy young (n = 40) and elderly (n = 40) adults to evaluate their decision making processes. There were significant differences in the learning curve of the two age groups, but no difference in overall IGT performance. The results for the first IGT block were different from those of the rest of the task, and the group of elderly adults had a better performance in this block. Elderly adults also showed a preference for deck A, the one that resulted in greater losses. Findings confirmed the results of other studies, which reported that the IGT block score is the variable with the greatest sensitivity to age in this instrument.     

Transtheoretical Model Constructs for Physical Activity Behavior are Invariant across Time among Ethnically Diverse Adults in Hawaii

OBJECTIVES: Physical activity (PA) research applying the Transtheoretical Model (TTM) to examine group differences and/or change over time requires preliminary evidence of factorial validity and invariance. The current study examined the factorial validity and longitudinal invariance of TTM constructs recently revised for PA. METHOD: Participants from an ethnically diverse sample in Hawaii (N=700) completed questionnaires capturing each TTM construct. RESULTS: Factorial validity was confirmed for each construct using confirmatory factor analysis with full-information maximum likelihood. Longitudinal invariance was evidenced across a shorter (3-month) and longer (6-month) time period via nested model comparisons. CONCLUSIONS: The questionnaires for each validated TTM construct are provided, and can now be generalized across similar subgroups and time points. Further validation of the provided measures is suggested in additional populations and across extended time points.
