Does socioeconomic status explain the relationship between admissions tests and post-secondary academic performance?

Critics of educational admissions tests assert that tests measure nothing more than socioeconomic status (SES) and that their apparent validity in predicting academic performance is an artifact of SES. The authors examined multiple large data sets containing data on admissions and related tests, SES, and grades showing that (a) SES is related to test scores (r = .42 among the population of SAT takers), (b) test scores are predictive of academic performance, and (c) statistically controlling for SES reduces the estimated test?grade correlation from r = .47 to r = .44. Thus, the vast majority of the test?academic performance relationship was independent of SES: The authors concluded that the test?grade relationship is not an artifact of common influences of SES on both test scores and grades.

Do interactions between personality and social-environmental factors explain smoking development in adolescence?

This study examined if the effects of peer smoking, family smoking, and parenting on smoking development during adolescence are moderated by personality characteristics of adolescents. Longitudinal data were obtained from 428 adolescents (aged M = 13.4, SD = .50) and their parents. Latent Growth Curve models assessed the development of smoking as a function of predictors and if effects of smoking-specific parenting and exposure to smoking were moderated by adolescents’ Big Five personality dimensions. Findings revealed that having peers who smoked was associated with an increased likelihood of being a smoker at baseline. Further, significant interactions revealed that adolescents lower in agreeableness were more likely to be a smoker at baseline if they had an older sibling who smoked or if their parents engaged in frequent smoking-related discussions with them and that effective smoking-specific conversation was more strongly related to smoking at baseline among adolescents who were highly emotionally stable. No interactions predicted growth in smoking over time yet significant main effects showed that growth in smoking was associated with higher levels of extraversion, lower levels of emotional stability, and less effective parental smoking-specific communication. This study highlights the relevance of personality-target interventions and policy programs directed at parents and peers. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Do "America's Best Hospitals" perform better for acute myocardial infarction?

BACKGROUND: "America's Best Hospitals," an influential list published annually by U.S. News and World Report, assesses the quality of hospitals. It is not known whether patients admitted to hospitals ranked at the top in cardiology have lower short-term mortality from acute myocardial infarction than those admitted to other hospitals or whether differences in mortality are explained by differential use of recommended therapies. METHODS: Using data from the Cooperative Cardiovascular Project on 149,177 elderly Medicare beneficiaries with acute myocardial infarction in 1994 or 1995, we examined the care and outcomes of patients admitted to three types of hospitals: those ranked high in cardiology (top-ranked hospitals); hospitals not in the top rank that had on-site facilities for cardiac catheterization, coronary angioplasty, and bypass surgery (similarly equipped hospitals); and the remaining hospitals (non-similarly equipped hospitals). We compared 30-day mortality; the rates of use of aspirin, beta-blockers, and reperfusion; and the relation of differences in rates of therapy to short-term mortality. RESULTS: Admission to a top-ranked hospital was associated with lower adjusted 30-day mortality (odds ratio, 0.87; 95 percent confidence interval, 0.76 to 1.00; P=0.05 for top-ranked hospitals vs. the others). Among patients without contraindications to therapy, top-ranked hospitals had significantly higher rates of use of aspirin (96.2 percent, as compared with 88.6 percent for similarly equipped hospitals and 83.4 percent for non-similarly equipped hospitals; P<0.01) and beta-blockers (75.0 percent vs. 61.8 percent and 58.7 percent, P<0.01), but lower rates of reperfusion therapy (61.0 percent vs. 70.7 percent and 65.6 percent, P=0.03). The survival advantage associated with admission to top-ranked hospitals was less strong after we adjusted for factors including the use of aspirin and beta-blockers (odds ratio, 0.94; 95 percent confidence interval, 0.82 to 1.08; P=0.38). CONCLUSIONS: Admission to a hospital ranked high on the list of "America's Best Hospitals" was associated with lower 30-day mortality among elderly patients with acute myocardial infarction. A substantial portion of the survival advantage may be associated with these hospitals' higher rates of use of aspirin and beta-blocker therapy.     

Do children endorse psychosocial factors in the transmission of illness and disgust?

The present studies examined beliefs concerning the impact of psychosocial factors in the transmission of contagious illness, injuries, and disgust. In Studies 1 and 2, participants ranging from preschoolers through adults judged the likelihood that a character would get sick (or injured) after being contaminated by another individual who was either of no stated relation to the character or who was a best friend, a disliked person, or a family member. Studies 3 and 4 examined effects of psychosocial relatedness on judgments of disgust (a psychological response). Study 5 examined the influence of germs on judgments of disgust. Overall, preschoolers through 2nd graders judged that any type of relatedness decreased the possibility of contracting illness from another person. However, for disgust, preschoolers judged that negative contagion would have a more powerful effect, particularly in the presence of germs. Relatedness had no effect on judgments of injury transmission. These results suggest that young children treat the psychological and biological domains as distinct but mutually interacting.

Do changes in drinking motives mediate the relation between personality change and “maturing out” of problem drinking?

Recent research has indicated that developmental changes in the personality traits of neuroticism and impulsivity correlate with changes in problem drinking during emerging and young adulthood. However, it remains unclear what potential mechanisms, or mediators, could account for these associations. Drinking motives, particularly drinking to regulate negative affect (drinking to cope) and to get “high” or “drunk” (drinking for enhancement), have been posited to mediate the relationship between personality and drinking problems. Recent work indicates that changes in drinking motives parallel changes in alcohol involvement from adolescence to young adulthood. The present study examined changes in drinking motives (i.e., coping and enhancement) as potential mediators of the relation between changes in personality (impulsivity and neuroticism) with changes in alcohol problems in emerging and young adulthood. Analyses were based on data collected from a cohort of college students (N = 489) at varying risk for alcohol use disorders from ages 18 to 35. Parallel process latent growth modeling indicated that change in coping (but not enhancement) motives specifically mediated the relation between changes in neuroticism and alcohol problems as well as the relation between changes in impulsivity and alcohol problems. Findings suggest that change in coping motives is an important mechanism in the relation between personality change and the “maturing out” of problematic alcohol involvement.

Do accident and emergency senior house officers know the British guidelines on the management of acute asthma?

Avoidable deaths from asthma continue, even in hospital. Since the management of acute severe asthma is often initiated in the Accident and Emergency department, it is crucial that staff there have adequate knowledge. An anonymous questionnaire, containing items based on chart 6 of the UK guidelines, was completed by 66 Accident and Emergency Senior House Officers from the Yorkshire region. The study aim was to establish these doctors' levels of knowledge about the recommended management of acute asthma in Accident and Emergency. The median score was 10 (out of a possible 24) and the interquartile range 8-13. Further efforts are required to implement these guidelines so that the best patient outcomes can be achieved.     

Do agonistic motives matter more than anger? Three studies of cardiovascular risk in adolescents.

Objectives: Three motivational profiles have been associated with recurring psychological stress in low-income youth and young adults: Striving to control others (agonistic striving), striving to control the self (transcendence striving), and not asserting control (dissipated striving). Agonistic striving has been associated with elevated ambulatory blood pressure during daily activities. Three studies tested the hypotheses that: (1) agonistic striving is associated with poor anger regulation, and (2) agonistic striving and poor anger regulation interactively elevate blood pressure. Design: Motivational profiles, anger regulation, and ambulatory blood pressure were assessed in a multiethnic sample of 264 urban youth. Main Outcome Measures: (1) anger regulation/recovery during laboratory challenge; (2) anger/blood pressure during daily activities (48 hours). Results and Conclusion: Replication of the profiles in distant cities showed they occur with similar frequency across differences of region, race, and gender. Analyses controlling for body size, race, and gender revealed that individuals with the agonistic striving profile had higher ambulatory pressure, especially during social encounters. They became more openly angry and aggressive when challenged but did not exhibit difficulty regulating anger in the laboratory, nor did they feel angrier during monitoring. However, individuals with the agonistic striving profile who did display poor anger regulation in the lab had the highest blood pressure; deficient self-regulatory capability amplified the positive association between agonistic striving and cardiovascular risk in both genders and all ethnic groups. Although anger is thought to increase cardiovascular risk, present findings suggest that anger and elevated blood pressure are coeffects of agonistic struggles to control others.

Do women's provider-role attitudes moderate the links between work and family?

The authors examined the links between mothers' work qualities and their individual well-being and marital quality, as well as adolescent daughters' and sons' gender-role attitudes, as a function of mothers' provider-role attitudes, in 134 dual-earner families. In home interviews, mothers described their work, provider-role attitudes, family relationships, and mental health; their offspring reported gender-role attitudes. Women's attitudes about breadwinning were coded into main-secondary, coprovider, and ambivalent coprovider groups. Mothers' provider-role attitudes moderated the links between status indicators and mothers' depression, marital conflict, and daughters' gender-role attitudes. For example, depression and marital conflict were negatively related to coprovider mothers' earnings and occupational prestige. The same was not true for main-secondary and ambivalent coprovider mothers. These findings underscore the importance of considering employed women's interpretation of their work roles when exploring work-family links.

Can the influence of childhood socioeconomic status on men’s and women’s adult body mass be explained by adult socioeconomic status or personality? Findings from a national sample.

Objectives: On the basis of a life-course risk-chain framework, the authors examined whether (a) residual associations between childhood socioeconomic status (SES) and adult obesity and body mass index (BMI) would be observed in women but not men after adjusting for adult SES, (b) adult Big Five personality traits would be associated with adult body mass in both genders, and (c) personality would explain unique variation in outcomes beyond child and adult SES. Design: National survey (Midlife Development in the United States study; N = 2,922). Main Outcome Measures: BMI and obesity. Results: (a) In both genders, association between childhood SES and adult obesity were accounted for entirely by adult SES, but its effect on adult BMI was observed only in women; (b) higher conscientiousness was associated with lower obesity prevalence and BMI in both genders, although more strongly in women, and in men, greater obesity prevalence was associated with higher agreeableness and neuroticism; and (c) personality explained unique outcome variation in both genders. Conclusions: Early social disadvantage may affect adult weight status more strongly in women owing to gender differences in the timing and nature of weight-management socialization. Personality may enhance or detract from risks incurred by childhood or adulthood SES in either gender, necessitating the consideration of dispositional differences in prevention and intervention programs.

Examining the relations between rumination and adjustment: Do ethnic differences exist between Asian and European Americans?

Past studies have pointed to the dysfunctional nature of rumination in adults. However, past research has not examined ethnic variations. Accordingly, this study examined ethnic differences in rumination in 184 Asian American and 238 European American college students. Consistent with expectations, Asian Americans were found to ruminate more than European Americans. However, rumination was found to have a weaker association with measures of adjustment (viz., affectivity, depressive symptoms, anxious symptoms, and life satisfaction) in Asian Americans compared with European Americans. As a result of conducting regression analyses to determine whether rumination was a unique predictor of functioning beyond affectivity, we found rumination to be a more distinct and useful predictor of functioning for Asian Americans than for European Americans. Overall, compared with findings for European Americans, our findings indicate that important ethnic differences need to be considered in studying rumination in Asian Americans.

Engaging families in longitudinal preventive intervention research: Discrete-time survival analysis of socioeconomic and social–emotional risk factors.

This study examined whether family risk factors predicted attrition in a prevention research project that incorporated procedures to increase retention in assessment and intervention activities. Analyses used data from 667 rural families collected over 4 waves and consisted of (a) young adolescent and parent reports of internalizing and externalizing problems, (b) observer ratings of distress in parent–child interactions, and (c) family socioeconomic status (SES). Analyses failed to identify any risk factors as significant predictors of intervention participation. Only SES was found to be significant as a predictor of assessment attrition. This SES result appeared to reflect an association between lower educational attainment and an increased likelihood of attrition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-perceived competence and the relation between life events and depressive symptoms in adolescence: Mediator or moderator?

In a 2-wave longitudinal study, 9th-grade students (N ?=?468) completed self-report measures of stressful life events, depressive symptoms, and 5 domains of self-perceived competence (i.e., academic competence, social acceptance, physical appearance, behavioral conduct, and athletic competence). Teachers and peers also reported about the participants' depressive symptoms. In longitudinal analyses, negative (but not positive) events related to depressive symptoms. Results suggested that self-perceived competence served as a mediator (but not a moderator) of this relation. Negative events predicted changes in self-perceived competence. Self-perceived competence predicted changes in depressive symptoms. Also, the direct effect of negative events on depressive symptoms diminished after controlling for self-perceived competence.

Too stressed out to participate? Examining the relation between stressors and survey response behavior.

Despite the use of survey-based organizational data in many studies of organizational behavior, survey response behavior and nonresponse are rarely studied phenomena. This study expands on previously proposed survey response and nonresponse frameworks by integrating the job stress literature. The authors investigated whether overload, role ambiguity, and role conflict experienced by individuals relate to survey response behavior. Using organizational citizenship behavior theory and social exchange theory as theoretical frameworks, the authors proposed that nonrespondents experience higher levels of stressors than respondents. Data collected in a longitudinal field study partially supported the hypotheses. As hypothesized, overload increased the likelihood of nonresponse. Contrary to hypotheses, role ambiguity decreased the likelihood of nonresponse. Role conflict was not significantly related to nonresponse.

High-level reasoning and base-rate use: Do we need cue-competition to explain the inverse base-rate effect?

Previous accounts of the inverse base-rate effect (D. L. Medin & S. M. Edelson, see record 1988-31640-001) have revolved around the concept of cue-competition. In this article, the authors propose that high-level reasoning in the form of an eliminative inference mechanism may contribute to the effect. A quantitative implementation of this idea demonstrates that it has the power by itself to produce the pattern of base-rate effects in the Medin and Edelson (1988) design. Four predictions are derived that contradict the predictions by attention to distinctive input (ADIT; J. K. Kruschke, see record 1996-02680-001), up to date the most successful account of the inverse base-rate effect. Results from 3 experiments disconfirm the predictions by ADIT and demonstrate the importance of high-level reasoning in designs of the Medin and Edelson kind. Implications for the interpretation of the inverse base-rate effect and the attention-shifting mechanisms presumed by ADIT are discussed.

Is the breast best for children with a family history of atopy? The relation between way of feeding and early childhood morbidity

BACKGROUND: Previous studies reported that breast-feeding protects children against a variety of diseases, but these studies were generally conducted on "high-risk" or hospitalized children. This paper describes the results of our study on the effects of breast-feeding on rate of illness in normal children with a family history of atopy. METHODS: A historic cohort approach of 794 children with a family history of atopy was used to assess the effects of breast-feeding on illness rates. Family history of atopy was based on allergic diseases in family members as registered by the family physician. Illness data from birth onwards were available from the Continuous Morbidity Registration of the Department of Family Medicine. Information on breast-feeding was collected by postal questionnaire. We then compared rates of illness between children with a family history of atopy who were and who were not breast-fed. RESULTS: Breast-feeding was related to lower levels of childhood illness both in the first and the first three years of life. In the first year of life they had fewer episodes of gastroenteritis, lower respiratory tract infections, and digestive tract disorders. Over the next three years of life they had fewer respiratory tract infections and skin infections. CONCLUSIONS: Our results suggest a protective effect of breast-feeding among children with a family history of atopy that is not confined to the period of breast-feeding but continues during the first three years of life. Breast-feeding should be promoted in children with a family history of atopy.     

Fluent, fast, and frugal? A formal model evaluation of the interplay between memory, fluency, and comparative judgments.

A new process model of the interplay between memory and judgment processes was recently suggested, assuming that retrieval fluency—that is, the speed with which objects are recognized—will determine inferences concerning such objects in a single-cue fashion. This aspect of the fluency heuristic, an extension of the recognition heuristic, has remained largely untested due to methodological difficulties. To overcome the latter, we propose a measurement model from the class of multinomial processing tree models that can estimate true single-cue reliance on recognition and retrieval fluency. We applied this model to aggregate and individual data from a probabilistic inference experiment and considered both goodness of fit and model complexity to evaluate different hypotheses. The results were relatively clear-cut, revealing that the fluency heuristic is an unlikely candidate for describing comparative judgments concerning recognized objects. These findings are discussed in light of a broader theoretical view on the interplay of memory and judgment processes. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Can the neurotrophic hypothesis explain degeneration and loss of plasticity in mature and ageing autonomic nerves?

The development of Ca-ATPase immunoreactivity in gerbil outer hair cells (OHCs), assayed by immunofluorescence and postembedding immunocytochemistry, is reported here. In the adult, a linear array of label is seen inside the lateral plasma membrane. The ultrastructural distribution of Ca-ATPase near the OHC lateral plasma membrane was examined using immunogold cytochemistry and showed this calcium pumping enzyme to be present throughout the subsurface cisternal complex (SSC), especially near the innermost layers. During development, Ca-ATPase immunoreactivity appeared in patches near the lateral plasma membrane of some OHCs of the third row by 12 days after birth (DAB). By 15-16 DAB, punctate immunoreactivity was detected in the second and first rows. At 20 DAB, immunostaining near OHC lateral plasma membrane was increased, but was less continuous than OHC staining in the adult cochlea. The appearance of Ca-ATPase in OHCs coincides with the onset of auditory function and isolated OHC motility in the gerbil. The ultrastructural demonstration of abundant sites of calcium pumps in the SSC supports a role for this structure in the intracellular storage of calcium. These findings suggest a possible role of Ca-ATPase and the SSC in the regulation of slow motility of OHCs which has been reported to depend on intracellular calcium concentration.     

Do logistic regression and signal detection identify different subgroups at risk? Implications for the design of tailored interventions.

Identifying subgroups of high-risk individuals can lead to the development of tailored interventions for those subgroups. This study compared two multivariate statistical methods (logistic regression and signal detection) and evaluated their ability to identify subgroups at risk. The methods identified similar risk predictors and had similar predictive accuracy in exploratory and validation samples. However, the 2 methods did not classify individuals into the same subgroups. Within subgroups, logistic regression identified individuals that were homogeneous in outcome but heterogeneous in risk predictors. In contrast, signal detection identified individuals that were homogeneous in both outcome and risk predictors. Because of the ability to identify homogeneous subgroups, signal detection may be more useful than logistic regression for designing distinct tailored interventions for subgroups of high-risk individuals.

But is it good for the psychologists? Appraisal and status of DSM-III.

Presents a critical analysis of the 3rd edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III). Improvements over DSM-II are acknowledged; it is suggested, however, that problems with larger issues (e.g., multiaxial, diagnosis, operational criteria, and the medical model) overshadow these positive features.

Do peers make the place? Conceptual synthesis and meta-analysis of coworker effects on perceptions, attitudes, OCBs, and performance.

The authors propose that broad aspects of lateral relationships, conceptualized as coworker support and coworker antagonism, are linked to important individual employee outcomes (role perceptions, work attitudes, withdrawal, and effectiveness) in a framework that synthesizes several theoretical predictions. From meta-analytic tests based on 161 independent samples and 77,954 employees, the authors find support for most of the proposed linkages. Alternative explanations are ruled out, as results hold when controlling for leader influences and mediation processes. The authors also observe differential strengths of coworker influence based on its valence, content, and severity, and on the social intensity of the task environment. The authors conclude with a call for more comprehensive, complex theory and investigation of coworker influences as part of the social environment at work.
