Does adolescent heavier alcohol use predict young adult aggression and delinquency? Parallel analyses from four Australasian cohort studies

While the association between heavy alcohol consumption and aggression has been well documented, the causal direction of this association, particularly at a population level, is disputed. A number of causal sequences have been proposed. First, that aggression leads to heavy alcohol use. Second, that heavy alcohol use leads to aggression. Third, that the association between alcohol use and aggression is due to confounding by (a) sociodemographic variables or (b) delinquency. We report here data from four Australasian prospective longitudinal studies of adolescents, to assess the temporal sequence of heavy drinking and aggression over the period from adolescence to young adulthood. The four cohort studies provide a total sample of 6,706 persons (Australian Temperament Project, n = 1701; Christchurch Health and Development Study, n = 931; Mater-University of Queensland Study of Pregnancy, n = 2437; Victorian Adolescent Health Cohort Study, n = 1637). We use multinomial logistic regression to determine whether early adolescent aggression predicts subsequent age of onset of heavy episodic drinking (HED), after adjustment for concurrent sociodemographic factors and delinquency. We then consider whether HED predicts subsequent aggression, after adjusting for past aggression, concurrent delinquency, and a range of confounders. There are broadly consistent findings across the four cohort studies. Early aggression strongly predicts subsequent HED. HED predicts later aggression after adjustment for prior aggression and other confounders. Policies that alter population levels of alcohol consumption are likely to impact on levels of aggression in societies where HED linked to aggression is more common.     

Parent-Child Interactions in Relation to Critical and Emotionally Overinvolved Expressed Emotion (EE): Is EE a Proxy for Behavior?

Expressed emotion measures, encompassing dimensions of criticism (CRIT), and emotional overinvolvement (EOI) are increasingly being used to assess the parent-child relationship in child clinical populations, despite the lack of studies assessing their validity. We examined the correspondence between CRIT, EOI, and parent-child interactions as observed by neutral coders in a sample of 252 clinic-referred children and adolescents, ages 7-17 years. We found support for the validity of the CRIT code, with high critical parents showing more antagonism, negativity, disgust, harshness, and less responsiveness, compared to parents who scored in the low or borderline ranges. In contrast, none of the observed behaviors were found to correspond with parental EOI, suggesting either that this construct lacks validity with juvenile samples or that behaviors that correspond to EOI are difficult to observe. We conclude that high parental CRIT can be used as an index of problematic parent-child interactions.     

Power at Work: Navigating Hierarchies,Teamwork and Webs

I explore tensions between the dynamics observed during a shadowing experience in a clinic and a hospital and theories of power and organizations. Commenting on what the tensions reveal about power at work (in the dual sense of how power works and power in the workplace), I suggest that some of the most gratifying experiences of workplace collaboration for healthcare professionals may occur as a result of their having successfully navigated complex coalitions of hierarchies, teams and webs rather than dutifully adhering to any single organizational structure.     

What's in a name for memory errors? Implications and ethical issues arising from the use of the term "false memory" for errors in memory for details

The term "false memories" has been used to refer to suggestibility experiments in which whole events are apparently confabulated and in media accounts of contested memories of childhood abuse. Since 1992 psychologists have increasingly used the term "false memory" when discussing memory errors for details, such as specific words within lists. Use of the term to refer to errors in details is a shift in language away from other terms used historically (e.g., "memory intrusions"). We empirically examine this shift in language and discuss implications of the new use of the term "false memories." Use of the term presents serious ethical challenges to the data-interpretation process by encouraging over-generalization and misapplication of research findings on word memory to social issues.     

Reliability and validity of the Spanish Version of the Crisis in Family Systems-Revised

Increasing the representation of Spanish-speaking study participants requires development and dissemination of reliable and valid translated scales. In the urrent study the construct validity was assessed of the Spanish version of the Crisis n Family Systems-Revised, a measure of contemporary life stressors, with a convenience sample of 377 parents interviewed in a study of childhood asthma, although over half of the respondents did not have children with asthma. Most respondents were foreign-born women between 20 to 60 years old (M=35, SD=7). 52% had not completed high school or its equivalent, and 55% reported a household income of dollar 15,000 or less. For a subsample of 25 respondents test-retest reliability was .86 over 2 wk. Reporting more life stressors was associated with greater depressive symptomatology, poorer physical and mental health function, and lower household income. These relationships support the construct validity of the test in Spanish. This study provided strong evidence that this version is a valid and reliable measure of life stressors for a Spanish-speaking population living in the United States.     

A validity study of the Positive Psychology Protective Profile

The purpose of this study was to conduct an exploratory factor analysis to provide support for the construct validity of the Positive Psychology Protective Profile, a self-report measure based on positive psychology. 985 undergraduates completed the profile, the Beck Depression Inventory, and the College Life Stress Inventory. Scores on the first two factor scores (Positive Outlook, Negative Symptoms) for the profile correlated significantly with scores on depression and stress, whereas scores on the third profile factor (Problem-solving) correlated significantly only with scores on the Beck Depression Inventory. Scores on the Positive Outlook significantly differentiated participants having either chronic illness or recent major illness from those who did not.
