Longitudinal moderators of the relationship between excessive drinking and intimate partner violence in the early years of marriage.

Alcohol problems are one of the most well-established risk factors for physical intimate partner violence. Nonetheless, most individuals who drink heavily do so without ever aggressing against a partner. Laboratory research identifies hostility as an important moderator of the association between alcohol and general aggression, and correlational research suggests that stress and coping may also be important moderators of the alcohol-aggression link. Building on this research, the authors examined hostility, coping, and daily hassles as moderators of the associations between excessive drinking and intimate partner violence across the first 4 years of marriage in a sample of 634 newly married couples. Excessive drinking was a significant cross-sectional correlate, but it did not emerge as a unique longitudinal predictor of intimate partner violence perpetration in this sample. However, alcohol was longitudinally predictive of husband violence among hostile men with high levels of avoidance coping. Findings generally supported the moderation model, particularly for men. These findings implicate hostility, coping, and daily hassles, as well as alcohol, as potentially important targets for partner violence prevention strategies for young married couples.

Socioeconomic and drug use determinants of smoking status in an urban adult population of Black African descent

We examined the influence of socioeconomics and drug use on current smokers (N = 137) and nonsmokers (N = 143) from an urban adult population of Black African descent. Median participant age was 33 years (range = 20-59). Smokers consumed a median of eight cigarettes/day (range = 0-35). Interestingly, 86% smoked fewer than 15 cigarettes/day and only 8% smoked menthol cigarettes. Socioeconomic and drug use variables significantly associated with smoking status in univariate analyses were included in a multiple logistic regression model that controlled for gender and age. Compared with nonsmokers, smokers were less likely to be university educated, more likely to be divorced, separated, or widowed, more likely to be current alcohol users, and more likely to be current marijuana users. Unexpectedly, household income and employment status were not associated with smoking status. Among current alcohol users, smokers consumed three times the number of drinks per month that nonsmokers consumed (p<.001). Among current marijuana users, smokers consumed more than five times the number of joints per month that nonsmokers consumed (p<.001). Overall, lower education levels, divorce, and alcohol and marijuana use were significantly associated with increased likelihood of smoking among this population.     

Effect of phytosterol structure on thermal polymerization of heated soybean oil

This study determined the effect of phytosterol structure, including the degree of unsaturation and the presence of an ethylidene group in the side chain, on the thermal polymerization of heated soybean oil. Indigenous tocopherols and phytosterols were removed from soybean oil by molecular distillation. Pure phytosterols were added back to the stripped soybean oil at concentrations of 0.5, 1.0, and 5 mg/g oil (0.05, 0.1, and 0.5 wt-%). These oils were heated at 180 °C over a period of 8 h, and triacylglycerol dimers and polymers, fatty acid composition, and residual phytosterol content were determined. None of the phytosterols prevented triacylglycerol dimer and polymer formation when used at 0.5 mg/g; however, phytosterols with two or more double bonds, regardless of the presence of an ethylidene group in the side chain, provided slight protection when added at 1 mg/g. Ergosterol addition at 5 mg/g reduced polymer formation by 16–20% compared to the control oil, but at this level none of the other phytosterols provided protection of any practical significance. Thus, under the conditions used for this heating study, the degree of phytosterol unsaturation was more important for its anti-polymerization activity than the presence of an ethylidene group.     

Internet–depression link?

Comments on the article by R. Kraut et al (see record 1998-10886-001) regarding links between Internet use and depression. Rierdan expresses conceptual and analytic concerns about whether Kraut et al actually assessed depression in their study or whether they found a relationship between Internet use and "depression" as they assessed it. The author expresses concern regarding the range of scores for Kraut et al study participants on the Center for Epidemiological Studies Depression Scale and argues that the most valid interpretation of the scores is that the Ss in this study had low levels of distress. As a group, they were not depressed before or after the study. The author raises a second analytic issue regarding analytic techniques, arguing that effect sizes for the group were actually very small. The author suggests that the finding of an association between Internet use and distress has few implications for public policy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Trauma exposure among children with oppositional defiant disorder and attention deficit–hyperactivity disorder.

Consecutive admissions to an outpatient child psychiatry clinic diagnosed with oppositional defiant disorder (ODD), attention deficit-hyperactivity disorder (ADHD), or adjustment disorder were assessed for trauma exposure by a structured clinical interview and parent report. Controlling for age, gender, severity of internalizing behavior problems, social competence, family psychopathology, and parent–child relationship quality (assessed by parent report), an ODD diagnosis, with or without comorbid ADHD, was associated with increased likelihood of prior victimization (but not nonvictimization) trauma. ADHD alone was not associated with an increased likelihood of a history of trauma exposure Traumatic victimization contributed uniquely to the prediction of ODD but not ADHD diagnoses. Children in psychiatric treatment who are diagnosed with ODD, but not those diagnosed solely with ADHD, may particularly require evaluation and care for posttraumatic sequelae.

Transferring psychotherapy clients: State of the art.

Transferring psychotherapy clients from one therapist to another is a common event that may pose clinical and administrative problems. Clinicians and therapists in training transfer clients when their professional role or activities change or when they leave their clinical settings. We review the literature on transferring psychotherapy clients and report on aspects of the transfer process and procedures used by a national sample of psychology training clinics. We also report and discuss the results of an exploratory analysis training clinic records in which we investigated the relation between transfer outcome (successful vs. unsuccessful) and a set of treatment and demographic factors. Last, we suggest several ways of handling difficulties that arise as a result of clinical and administrative reassignment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Analysis of biogenic amines in a single Drosophila larva brain by capillary electrophoresis with fast-scan cyclic voltammetry detection

Drosophila, the fruit fly, is a common model organism in biology; however, quantifying neurotransmitters in Drosophila is challenging because of the small size of the central nervous system (CNS). Here, we develop neurotransmitter quantification by capillary electrophoresis with fast-scan cyclic voltammetry (CE-FSCV) detection, which allows peak identification by both migration time and the cyclic voltammogram, in contrast to traditional amperometric detection which provides no chemical identification. Tissue content of biogenic amine neurotransmitters was determined in a single CNS dissected from a Drosophila larva. Low detection limits, 1 nM for dopamine and serotonin, 2.5 nM for tyramine, and 4 nM for octopamine, were achieved using field-amplified sample stacking by diluting the homogenized tissue with percholoric acid and acetonitrile. Two different strains of wild-type flies, Oregon R and Canton S, have similar dopamine and serotonin levels but different octopamine content. When flies are fed NSD-1015, which inhibits dopamine decarboxylase (Ddc) a synthesis enzyme in the dopamine and serotonin pathways, dopamine significantly decreases by 52%. A genetically altered driver line, Ddc-GAL4, had lower serotonin and dopamine content as did w(118) flies. When the Ddc-GAL4 line was used to produce flies overexpressing the serotonin synthesis enzyme tryptophan hydroxylase (Ddc-GAL4;UAS-Trh), the serotonin tissue content was greater than for Ddc-GAL4 but not significantly different than the wild-type. These results show that CE-FSCV is useful for monitoring the impact of genetic and pharmacological manipulations on the content of multiple neurotransmitters in a CNS from a Drosophila larva.     

Factors related to the satisfaction and performance of temporary employees.

Previous research suggests that whether temporary employees are voluntary or involuntary in their choice to pursue temporary work is related to satisfaction levels. This study investigated whether voluntarily or involuntarily pursuing temporary work is related to satisfaction and performance. Previous work has classified individuals as voluntary or involuntary when operationalizing the decision to pursue temporary work. This study used a more complex measure that addressed individuals' reasons for pursuing temporary work. Analyses were conducted using the complex measure and a traditional classification. The results suggest 4 conclusions: (a) a complex measure may be preferred over a dichotomous classification when operationalizing the decision to pursue temporary work, (b) individuals who are involuntarily pursuing temporary work may be less satisfied, (c) whether an individual voluntarily pursues temporary work appears to be unrelated to satisfaction levels, and (d) whether an individual is voluntarily or involuntarily pursuing temporary work is unrelated to performance.

Linguistic immediacy of schizophrenics in different proxemic conditions.

The linguistic immediacy of 32 schizophrenic and 32 nonschizophrenic psychiatric patients was observed as Ss sat in 1 of 4 proxemic positions during a short interview. Positions varied in terms of distance between patients and interviewer (near vs far) and direction of the interviewer's eye gaze (gazing continuously vs never looking at patients). Results indicate that the immediacy of schizophrenics' verbal communication varies as a function of patient–interviewer distance and orientation.

Considerations in the nutritional management of patients with acute renal failure

Despite improvements in medical and dialytic therapies, mortality rates for patients with complicated acute renal failure (ARF) remains tragically high-above 50%. Mortality rates also remain persistently high in patients with ARF and preexisting or hospital-acquired malnutrition. ARF causes significant changes in substrate utilization largely because of the metabolic consequences of acute uremia compounded by underlying stress from acute illness. Alterations in protein or amino acid, carbohydrate, and lipid metabolism as well as fluid, electrolyte, and acid-base balance need to be considered when providing nutritional therapy in patients with ARF. Also, the degree of renal impairment, which influences the need for renal replacement therapy (RRT), impacts nutritional requirements. As medical management is becoming highly aggressive in treating ARF with RRT, the ability to provide adequate nutrition is enhanced; however, no consensus on optimal caloric and macro-/micronutrient requirements is available. More current research is required to clarify nutritional needs of this patient population. Nevertheless, individualizing nutrition care and integrating nutritional therapies within a team setting is essential in providing optimal patient care in the presence of ARF.
