Competitiveness mediates the link between personality and group performance

The performance of individuals within groups, and of groups as units, is the product of immediate goal structures and personality differences pertinent to those goals among group members. A level-of-analysis approach linked the dimension of agreeableness to situated competitiveness and task performance in group settings. Hypotheses were (a) individual differences in self-rated and other-rated competitiveness are related (inversely) to the Big Five dimension of agreeableness, (b) immediately situated promotive and contrient goal structures influence self-ratings of competitiveness, (c) immediate goal structures differentially activate competitiveness to affect task performance in groups, and (d) agreeableness effects on task performance are partially mediated by competitiveness. Structural equation modeling corroborated hypotheses about the links among agreeableness, competitiveness, and task performance.     

Interindividual-Intergroup Discontinuity as a Function of Trust and Categorization: The Paradox of Expected Cooperation.

Two experiments used a 3-choice variation of the prisoner's dilemma game to explore the paradoxical implications of expected cooperation of other groups and individuals for competitiveness and cooperativeness. Experiment 1 found that an experimental manipulation of opponent trustworthiness influenced the tendency of both groups and individuals to cooperate but had no significant effect on the tendency of groups and individuals to compete-possibly because of the perceived unfairness of competing with a trustworthy other. Experiment 2 found that an experimental manipulation of categorization increased the tendency of same-category groups and individuals to cooperate (as in Experiment 1) and also increased the tendency of same-category groups, but not individuals, to compete (unlike in Experiment 1). It was further found that the tendency of same-category groups to compete more than same-category individuals was relatively stronger for participants high in guilt proneness.

Performance following ability-focused physical therapy intervention in individuals with severely limited physical and cognitive abilities

BACKGROUND AND PURPOSE: Do individuals with severely limited physical and cognitive abilities improve their gross motor abilities when given physical therapy intervention, and does improvement transfer to nontreatment settings? SUBJECTS: The subjects were 24 individuals (10 female, 14 male), aged 3 to 30 years (X = 20.1, SD = 8.1), who were nonambulatory and had limited adaptive behavior. METHODS: Change in gross motor ability during 18 weeks of twice-weekly therapy was measured using goal attainment scaling (GAS). Three gross motor goals were developed for each subject based on individual or caregiver needs, with one goal randomly selected as a control. Physical impairments were treated, and behavioral management principles, low-level communication approaches, high-repetition practice of goals, and a progressive reduction of both physical assistance and multisensory cues were used. An independent rater scored goal level from randomly ordered videotapes recorded during therapy and in recess and home settings. RESULTS: Mean GAS T scores were higher for treatment goals (X = 45.6, SD = 10.5) compared with control goals (X = 34.6, SD = 11.8). When the expected goal level (50) was met during therapy, mean GAS T scores in recess settings ( X = 35.9, SD = 11.5) and home settings (X = 42.2, SD = 12.2) were lower. At the conclusion of therapy, there were no differences in goal levels between treatment and control goals in both the recess and home settings. CONCLUSION AND DISCUSSION: The subjects demonstrated improvement of gross motor abilities practiced during therapy. Level of ability during therapy, however, did not consistently transfer to the recess of home settings. [Brown DA, Effgen SK, Palisano RJ.

Supporting the free exercise of religion in the group home context

Ways were delineated in which group home employees can support individuals living in the home in the active expression of faith, both inside and outside the group home environment, and at the same time protect the freedom of others in the home who choose not to be involved in religious activities. After briefly reviewing some assumptions underlying the 1992 AAMR definition of mental retardation and describing the capability of religious expression for individuals with cognitive impairment, we presented several guidelines to assist group home staff members.     

A longitudinal study of AIDS conversations between mothers and adolescents

This paper presents the results of a study on the introduced, free-ranging patas monkey population of Southwestern Puerto Rico (SWPR). It describes information on the population size, social group composition, diet, daily ranging patterns, and patas home range during a 3 year period. The patas monkey population in the study area consisted of approximately 120 individuals in four heterosexual groups and several all-male bands. Within their home ranges (26.8 km2), the population density was 4.47 individuals/km2. Home range size among the population's four heterosexual groups varied from 3.72 km2 to 15.39 km2, and minimum daily distance traveled ranged from 0.8-2.0 km. In general, the social structure and mating system of this population parallels what has been described for African populations. However, habitat use, ranging behavior, and the quality of intergroup interactions suggests that patas of this population exhibit territorial behavior.

Individual-group discontinuity as a function of fear and greed.

Two studies tested the schema-based distrust interpretation of the tendency of intergroup relations to be more noncooperative (or competitive) than interindividual relations. According to this interpretation, anticipated competitiveness rationally leads to noncooperativeness or defensive withdrawal. Thus, the postulated motivation is fear of the group's competitive intent. Study 1 was a nonexperimental investigation in which discussion of distrust of another group was assessed and correlated with the number of cooperative choices. As predicted, the greater the within-group discussion of distrust for the other group, the less the number of cooperative choices. Study 2 was an experimental investigation that included as independent variables intergroup versus interindividual relations and PDG matrix versus PDG-Alt matrix (PDG matrix plus a third Alt or withdrawal choice producing intermediate outcomes regardless of the opponent's choice). As predicted, there were more withdrawal choices on the PDG-Alt matrix for groups than for individuals. However, it was still found that on the PDG-Alt matrix (where a safe withdrawal choice is possible), groups competed more than individuals.

Population reference values of the Spanish version of the Health Questionnaire SF-36

BACKGROUND: Perceived health status measurements reference values an important information source for health services research. Population-based norms have been proposed to increase their interpretability. In this paper, we have obtained the norms of the Spanish version of the SF-36 Health Survey and have compared them with US norms the questionnaire. MATERIAL AND METHODS: Data were obtained in the home interview survey on drug consumption (February 1996). This is a cross-sectional study of a multi-stage, stratified random sample of non-institutionalized individuals 15 and older residents in Spain. The final sample included 9,984 individuals, but the analysis is based on those individuals 18 or older (n = 9,151). Personal home interviews were carried out. Information included: the SF-36, legal and illegal drugs consumption, and socio-demographic data, among others. Central trend and dispersion statistics were estimated for each of the SF-36 dimension scores according to gender and age group. Cronbach's alpha coefficients were calculated to estimate the reliability of scores. RESULTS: For most SF-36 dimensions, scores were higher (better) among men and among younger age groups (p < 0.01). There was a monotonic score gradient by age which was more intense for physical function and bodily pain. All Cronbach's alpha coefficients were higher than 0.7 (ranging from 0.78 to 0.96). Spanish norms were very similar to those obtained in the US. CONCLUSIONS: Results presented should be considered the population-based norms of the Spanish version of the SF-36 Health Survey and may be useful for interpreting the questionnaire scores. These norms, which are very similar to the original US questionnaire both in absolute values and in the gender and age group distribution patterns, should be carefully used. Considerations for use discussed in the paper should be taken into account.

The home health aide as a member of the home healthcare team

Individuals of all ages are discharged from acute-care facilities with a variety of medical and nursing diagnoses. Many of these individuals require home health aides services in addition to their skilled care. In the changing healthcare environment of the 1990s, home healthcare professionals are being challenged to provide effective, skilled care that is the most cost-effective and appropriate for patients. It is important that all professional home healthcare personnel work as a team with home health aides to accomplish these goals. The home health aide is an important member of the home care team.     

Groupdrink: The effects of alcohol on intergroup competitiveness.

Alcohol is often consumed in group settings. The present article examines the effect of alcohol on intergroup competitiveness through the use of a prisoner's dilemma game. One hundred fifty-eight college students participated in the study, either individually or as a member of a 4-person experimental single-sex group. Participants consumed either alcohol (1.13 g ethanol/kg body weight) or a placebo. Results show no effect of alcohol on cooperative choice within individuals. However, groups were significantly less cooperative after consuming alcohol than they were after consuming a placebo. In addition, after consuming alcohol, groups were less cooperative than were individuals. Results are discussed in terms of the way alcohol may affect focus of attention on group-level cues.

Interindividual-intergroup discontinuity in the domain of correspondent outcomes: The roles of relativistic concern, perceived categorization, and the doctrine of mutual assured destruction.

Most prior research on the tendency for groups to be less cooperative than individuals (the interindividual-intergroup discontinuity effect) has used the Prisoner's Dilemma Game (PDG). Experiment 1 examined the discontinuity effect with 3 additional matrices: Chicken, Leader, and Battle of the Sexes (BOS). Unlike the PDG, these matrices are characterized by correspondence of outcomes. The discontinuity effect was significant for the PDG and Chicken matrices only. With the BOS and Leader matrices, both individuals and groups pursued outcome maximization through coordinated turn taking. Despite the lesser competitiveness, sets of interacting participants in the BOS and Leader conditions did perceive that they were 2 groups. Experiment 2 examined the discontinuity effect in 2 Chicken matrices with varying outcomes associated with mutual competition. Consistent with the doctrine of mutual assured destruction, the discontinuity effect was eliminated for the matrix in which mutual competition was associated with very low outcomes. Although concern for relative in-group standing gave rise to intergroup competition even in the domain of correspondent outcomes, such concern was constrained to the extent that it interfered with outcome maximization.

Mitigation of the somnolence of insulin-induced hypoglycemia by a vasopressin V1 receptor antagonist in the rhesus monkey

In order to estimate the risk of tuberculosis infection among employees in the funeral service industry, we conducted a risk-assessment study of a convenience sample of funeral home employees. Study participants completed a risk-assessment questionnaire and underwent tuberculin skin testing. Of 864 employees tested, 101 (11.7%) had a reactive tuberculin skin test. Reactivity to the tuberculin skin test was significantly associated with job category; funeral home employees with a present or past history of embalming deceased-human remains were twice as likely to be reactive as were non-embalming personnel (14.9% versus 7.2%, P < 0.01). Reactivity was also associated with age, gender, race, past history of close contact with a person diagnosed with tuberculosis, and work history. After controlling for age and other factors, tuberculin reactivity was found to be associated in embalming personnel with the number of years spent performing embalmings (> or = 20), and, in non-embalming personnel, with a history of close contact with infected individuals. Based on these results, it is recommended that funeral home employees who routinely embalm cadavers undergo annual tuberculin skin testing, receive initial training on tuberculosis prevention, and wear respiratory protection when preparing known tuberculosis cases.     

Longitudinal prescribing patterns of psychotropic drugs in nursing home residents.

Changes in the use of psychotropic drugs in a large nursing home were examined both in terms of usage for the total facility and in longitudinal changes within individuals. Data for the nursing home showed a gradual increase in use of antidepressants; a decrease in use of antianxiety medications and of sedative-hypnotics. Changes in the number of residents prescribed antipsychotics were not marked. Data within residents showed a great variability in number of psychotropic drugs used, in number of changes in dosage, and in specific patterns of medication change. The first drug change after admission (excluding day of admission) was more likely to involve initiation rather than discontinuation of psychotropic drugs. The medications studied were used over 4–7 months on the average, covering 20–30% of the resident's nursing home stay. The findings suggest that there is continued monitoring of psychotropic medications in the nursing home. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

The effects of health, environmental, and socio-psychological variables on fear of crime and its consequences among urban black elderly individuals

Despite extensive research on fear of crime among elder members of the population, little attention has been paid to the fear of crime among Black urban elderly individuals. Using a sample of 372 low income urban Black persons aged sixty-two and over the causes and consequences of such fear were investigated. Fear of crime reduces subjective well-being of these older adults and limits their mobility. Age, gender, education, marital status, loneliness, self-reported health status, previous victimization experience, media exposure, trust of neighbors, length of residence, and type of housing were tested to identify significant predictors of fear of crime. Some of these variables had a diverse impact on fear of crime at home versus outside of the home. For example, while gender was the strongest predictor of fear of crime outside the home, it was not significantly associated with fear inside the home. Surprisingly, self-reported health status was not related to fear of crime among this sample of urban Black elderly individuals.     

Time to nursing home admission for persons with Alzheimer's disease: the effect of health care system characteristics

OBJECTIVE: To study the influence of state health care system characteristics on time to nursing home admission (NHA) for persons with Alzheimer's disease (AD). METHOD: Up to nine years of Consortium to Establish a Registry for Alzheimer's Disease (CERAD) data on 639 non-Latino White individuals were merged with longitudinal data from the 28 states in which the CERAD participants resided. The state variables reflected characteristics of each state's long-term care (LTC) system, including Medicaid LTC spending practices and the supply of LTC providers. Cox Proportional Hazards Models with time-varying covariates were used to evaluate the risk factors associated with time to NHA. RESULTS: There was differential influence of state variables by marital status. For unmarried non-Latino White persons with AD, a higher percentage of Medicaid LTC spending on home and community-based services (HCBS) was significantly associated with a longer time to NHA. For married persons, a greater number of home health agencies was associated with a longer time to NHA. Other associations also varied by marital status. CONCLUSION: Study findings support the utility of targeted continued expanded provision of HCBS by states and provide a basis for future research regarding the impact of changing state health care systems on LTC utilization for persons with AD.     

An overview of the etiology, diagnosis, and treatment of Alzheimer disease

Alzheimer disease (AD) is the most common form of dementia affecting elderly people. It is the fourth leading cause of death among adults in the United States, following heart disease, cancer, and stroke. The prevalence of AD increases with increasing age. An estimated 10% of people aged 65 years have this progressive, degenerative disease, and this percentage increases to 47.2% for people aged 85 years and older. An early-onset form of AD can affect individuals who are middle-aged, with the youngest documented case being that of a 28-year-old. In the Framingham cohort, women with AD outnumbered men by a ratio of 2.8:1 for those aged 75 years or older. Undoubtedly, as our population continues to age, the increasing prevalence of AD will have an even greater impact on society than it does today. Approximately 4 million Americans have AD, and it is projected that the number will rise to 14 million by the middle of the next century. The financial impact of AD is staggering, with the average lifetime cost for an individual with AD exceeding $170,000. Although the majority of individuals with AD are cared for by family and friends at home, individuals with AD constitute half of all nursing home residents. The average cost of a year of nursing home care for an individual with AD is $42,000, and this cost can exceed $70,000. The purpose of this article is to provide an overview of the etiology of AD, the tools used in the diagnosis of AD, and the treatment of individuals with AD. In addition, the clinical presentation of the various stages of AD is described, and the psychosocial implications of this disease are discussed.
