Alcohol‐aggression expectancies and dispositional aggression moderate the relationship between alcohol consumption and alcohol‐related violence

Alcohol consumption increases aggression, but only in some drinkers. This study examines how expectancies for alcohol‐induced aggression and dispositional aggression moderate the link between alcohol consumption and alcohol‐related violence, building on previous studies that have employed limited measures of alcohol‐related violence and included few women. A sample of 212 men and women reported their alcohol consumption, alcohol‐aggression expectancies, dispositional aggression, and incidents of alcohol‐related aggressive acts. Alcohol‐aggression expectancies and quantity of alcohol consumed interacted to predict alcohol‐related aggression. Alcohol‐aggression expectancies covaried with alcohol‐related aggressive acts, particularly in heavier drinkers. Dispositional aggression also correlated with alcohol‐related aggression among heavier drinkers. These results help identify that alcohol might increase aggression only among heavy drinkers who expect alcohol to increase aggression or who are dispositionally aggressive. Aggr.

The Development of Scientific Talent in Westinghouse Finalists and Members of the National Academy of Sciences

This paper reports the results of two studies on the development of scientific talent among the scientific elite: finalists in the Westinghouse Science Competition and members of the National Academy of Sciences (NAS). Sampling four cohorts of finalists, we examined whether these gifted teenagers actually do go on to be the best scientists of the next generation by coding education and career outcomes. Finalists were quite successful and stayed mostly within science and medicine for their career choice. A rather high—although marginally unequal—portion of male (91%) and female (74%) finalists earned a doctoral degree. Women were also more likely to change to non-scientific professions than men. Among the most compelling findings from the NAS study were: age that scientific talent was recognized by self and others was an important predictor of early publication, which in turn was an important predictor of lifetime productivity. Growth curve analyses suggested a cubic model best fit productivity data over time. Moreover, in both samples there was an association between scientific achievement and recent immigrant status. Various theoretical models are discussed as possible explanations for the developmental, gender, and immigrant-status findings on scientific talent.     

Health Behaviors of Childhood Cancer Survivors: What We’ve Learned

There has been a dramatic increase in the number of childhood cancer survivors due to improved cancer treatments. However, these survivors are at risk for numerous late-effects as a result of their cancer therapy. Engaging in health-protective behaviors and limiting risky health behaviors are vitally important for survivors given their increased risks and physical late-effects. For this paper, we systematically reviewed the literature on childhood cancer survivors’ health behaviors by searching for published data and conference proceedings using computerized databases and references, and summarized these results. We examined the literature describing the prevalence of a variety of health behaviors among survivors, identifying significant covariates, and describing health behavior interventions. Finally, we provided research recommendations and discussed an ongoing study designed to address some of the limitations in the existing literature. The research to date is limited and recommendations for future studies are outlined.     

Acute effects of alcohol on cardiovascular reactivity to stress in college-age Type A (coronary prone) individuals

Healthy college-age males and females classified as Type A or Type B were randomly assigned to an alcohol (N=24) or a no-alcohol condition (N=24). Subjects were exposed to a verbal stress quiz while blood pressure, heart rate, peripheral vascular response (PVR), and self-reported anxiety indices were monitored. Results indicated that alcohol effected a reduction in resting levels of systolic blood pressure and a tonic reduction in the peripheral vascular response. Alcohol attenuated the systolic blood pressure, heart rate, and PVR to stress and efffected a decrease in anxiety following the Stressor. When analyzed relative to the participants' drinking experience, data indicated that the strongest stress-modulating effect of alcohol was evidenced by Type A subjects who have been identified as long-term drinkers. During recovery from stress Type A subjects identified as short-term drinkers maintained high levels of PVR. Types A and B subjects who did not ingest alcohol evidenced high PVR levels during stress. The findings are discussed in terms of the protective action of moderate chronic alcohol use on cardiovascular disease risk reduction in persons evidencing the coronary-prone behavior pattern.     

Cry analysis detects subclinical effects of prenatal alcohol exposure in newborn infants

The threshold, latency, and peak fundamental frequency (basic pitch) of crying were sensitive to the subclinical effects of prenatal alcohol exposure through the first month of postnatal life. Whereas infants with prenatal alcohol exposure showed a lower cry pitch and higher cry threshold at 2 days of age, higher pitched cries, typical of nervous system insult, were evident at 14 and 28 days. A longer latency was also evident at 14 days.     

Adolescent suicidal behaviors as a function of depression,hopelessness, alcohol use,and social support: A longitudinal investigation

Surveyed two high school cohorts (ns=698 and 283) to study independent prospective predictors of adolescent suicidal behaviors (thoughts, communicatio to others, attempts). Within each cohort, there were two measurements conducted 6 months apart. Structural equation models were tested, with depressive symptoms, hopelessness, alcohol consumption, social support, and gender serving as predictors. In the larger cohort, depression predicted later levels of all three suicidal behaviors controlling for baseline suicidal behaviors. Also, suicidal thoughts predicted later communications, and suicide attempts predicted future thoughts. In the smaller cohort, alcohol consumption predicted all three suicidal behaviors at the later measurement, whereas depression was predictive only of later thoughts. Major issues regarding prevention, theories of suicide and negative affect, and methodological/analytical approaches were discussed.     

Delayed matching-to-sample performance: Effects of relative reinforcer frequency and of signaled versus unsignaled reinforcer magnitudes

Six pigeons were trained on a delayed red-green matching-to-sample task that arranged four delays within sessions. Matching responses intermittently produced either 1.5-s access to food or 4.5-s access to food, and nonmatching responses produced either 1.5-s or 4.5-s blackout. Two phases were conducted: a signaled phase in which the reinforcer magnitudes (small and large) were signaled by houselights (positioned either on the left or right of the chamber), and an unsignaled phase in which there was no correlation between reinforcer magnitude and houselight position. In both phases, the relative frequency with which red and green matching responses produced food was varied across five values. Both matching accuracy and the sensitivity of performance to the distribution of reinforcers for matching responses decreased with increasing delays in both phases. In addition, accuracy and reinforcer sensitivity were significantly lower on signaled small-reinforcer trials compared with accuracy and sensitivity values on signaled large-reinforcer trials and on both types of unsignaled trials. These results are discussed in the context of research on both nonhuman animal and human memory.     

Evaluating the vermont system of care: Outcomes associated with community-based wraparound services

Evaluation of innovative community-based interventions is becoming a high priority for child and adolescent mental health service system research. The present study examined outcomes for a sample of Vermont children (N=27) experiencing emotional and behavioral problems and receiving individualized, wraparound services. One year after initiation of wraparound care, incidence of negative behaviors rated as placing a child at risk of removal from the community had decreased significantly, compliance behavior had increased, and a significant decline in Total Problem Behavior scores on the Child Behavior Checklist was observed. In addition, though 70% of the participants had previously required inpatient or residential treatment, 89% were maintained in the community after one year of services, and the total cost of services was less than that of out-of-state residential care. Although further comparative research is needed, this study suggests that for many of these children, wraparound services may be a more efficient intervention than long-term psychiatric hospitalization or residential treatment.     

Outcomes in a System of Care for Youths with Emotional and Behavioral Disorders: An Examination of Differential Change Across Clinical Profiles

We assessed the utility of an empirically-derived classification system for youths with emotional and behavioral disorders in a system of care with a strong representation of juvenile delinquents. Eighty-seven youths served in a system of care were categorized by variables related to past history, current behavioral functioning, and current psychological functioning into four clinical clusters. We evaluated preliminary clinical outcomes after six months of interagency involvement for youths within each cluster and across the four clusters. Results indicated that youths in different clusters improved significantly in need-specific areas. Trends in our data indicated differential change in clinical outcomes across clusters. We discuss our findings within the context of emerging outcomes of youths involved in comprehensive community-based programs and consider implications for outcome research, treatment of juvenile delinquents, and mental health policy.     

Outcomes of children with emotional disturbance in residential treatment for educational purposes

A study was conducted of the outcomes of all children and adolescents (N=114) with serious emotional disturbance who had been placed by school districts in residential treatment facilities for educational purposes over a three-year period. Both cost and outcome analyses were conducted. Cost analyses indicated a total annual expenditure in excess of $5 million, or $80,000 per youth per length of stay. Outcome analyses, consisting of ratings of outcomes and outcome interviews with special education directors, revealed that 63% of the youth had either made no or minimal progress, had been discharged with a negative outcome, or had run away. Positive outcomes were achieved in only 25% of the cases, measured by the students' return to school or placement into a vocational training program. Another 11% of the youth were making substantial progress. Analyses of the relationships between outcomes and cost revealed no relationship. However, positive outcomes were associated with shorter lengths of stay. Further, students in the positive outcome categories had more severe functioning deficits at intake than students in the negative outcome categories. The availability of community-based services for the student and family was the single most likely reason reported by special education directors for positive discharge status.
