Stress and Immunity: Age Enhances the Risks

A competent immune response is central to good health. There is good evidence that both aging and psychological stress can dysregulate immune function, resulting in changes in various aspects of the immune response that are large enough to have consequences for health. Older adults appear to show even greater immunological impairments associated with stress or depression than younger adults. Thus, the data suggest that aging interacts with stress and depression to enhance risks for morbidity and mortality among older adults.     

Characteristics of a French African Caribbean Epidemiological Psychiatric Sample with a History of Suicide Attempt

Research on vulnerability factors among ethnic groups, independent of primary psychiatric diagnosis, may help to identify groups at risk of suicidal behavior. French African Caribbean general psychiatric patients (N = 362) were recruited consecutively and independently of the primary psychiatric diagnosis. Demographic and clinical characteristics and lifetime history of suicide attempts were recorded. Sixty‐five patients (18%) had a history of at least one suicide attempt. Presence of professional qualifications, children, poor social contacts, treatment with benzodiazepine at inclusion, and poor treatment compliance were all associated with a lifetime history of suicide attempts.     

Do Geographic Regions with Higher Suicide Rates also have Higher Rates of Nonfatal Intentional Self‐Harm?

Fatal and nonfatal intentional self‐harm events in eight U.S. states were compared using emergency department, hospital, and vital statistics data. Nonfatal event rates increased by an estimated 24.20% over 6 years. Case fatality ratios varied widely, but two northeastern states' total event rates (fatal plus nonfatal) were very high (New Hampshire 206.5/100,000 person years; Massachusetts 166.7/100,000). Geographic context did not uniformly impact the likelihood of self‐harm across event types. The state‐level public health burden posed by such acts cannot, therefore, be accurately estimated from either mortality or morbidity data alone.     

The Beliefs in the Inheritance of Risk Factors for Suicide Scale (BIRFSS): Cross‐Cultural Validation in Estonia,Malaysia, Romania,the United Kingdom,and the United States

The genetics of suicide is increasingly recognized and relevant for mental health literacy, but actual beliefs may lag behind current knowledge. We examined such beliefs in student samples (total N = 686) from Estonia, Malaysia, Romania, the United Kingdom, and the United States with the Beliefs in the Inheritance of Risk Factors for Suicide Scale. Cultural effects were small, those of key demographics nil. Several facets of construct validity were demonstrated. Marked differences in perceived plausibility of evidence about the genetics of suicide according to research design, observed in all samples, may be of general interest for investigating lay theories of abnormal behavior and communicating behavioral and psychiatric genetic research findings.     

EMPOWERING TOKEN WOMEN LEADERS

We hypothesized that, in a masculine task, only token women leaders who were empowered through position (by being appointed leader) and expertise (trained with task-relevant information) and legitimated by a male experimenter as credible would be more effective in influencing the performance of their all-male groups than appointed-only and appointed-trained leaders. Thirty women undergraduates each led a small group of male students on a moon survival task. The hypothesis was supported. Videotapes of group interactions revealed that appointed-trained leaders interrupted group members and used tentative tag questions in failed attempts to share their task-relevant knowledge. In addition, group members reported the most dissatisfaction with appointed-trained leaders who, without legitimacy, violated diffused gender roles by presuming to be expert on a masculine task. The importance of the organizational empowerment of token women is underscored.     

Self-esteem of female athletes and nonathletes relative to sex role type and sport type

The purpose of the present research was to investigate the relationship of the self-esteem of female athletes and nonathletes to sex role type and sport type. The athletic group was comprised of 75 female collegiate athletes from eight sports and the nonathletic group consisted of a random sample of 75 female nonathletes. An assessment of self-esteem and sex role type was completed through administering to all subjects the short form of the (PRF) ANDRO Scale of Masculinity and Femininity, and the Interpersonal Disposition Inventory (IDI). On the basis of the results of the IDI, the subjects were categorized into four sex role types: androgynous, masculine, feminine, and undifferentiated. Based upon previous research, it was predicted that (1) athletes would exhibit higher self-esteem scores than nonathletes, (2) the self-esteem of androgynous individuals would be higher than other sex role types, (3) the self-esteem of feminine or undifferentiated individuals would be lower than other sex role types, (4) the self-esteem of female athletes in higher femininity status sports would be greater than those in lower femininity status sports, and (5) there would be a greater proportion of androgynous athletes and feminine nonathletes. The following significant results were found: nonathletes in the feminine sex role type were lower in self-esteem than all other groups; and there was a greater proportion of androgynous athletes and feminine nonathletes than expected by chance. There were no differences in self-esteem of athletes in higher femininity status vs lower femininity status sports. These findings were discussed relative to past research, and the potential impact of sport on the psychosocial development or selection of certain sex role types.     

The role of spatial complexity in the perception of speech and pure tones in dichotic listening

Ear advantages for CV syllables were determined for 28 right-handed individuals in a target monitoring dichotic task. In addition, ear dominance for dichotically presented tones was determined when the frequency difference of the two tones was small compared to the center frequency and when the frequency difference of the tones was larger. On all three tasks, subjects provided subjective separability ratings as measures of the spatial complexity of the dichotic stimuli. The results indicated a robust right ear advantage (REA) for the CV syllables and a left ear dominance on the two tone tasks, with a significant shift toward right ear dominance when the frequency difference of the tones was large. Although separability ratings for the group data indicated an increase in the perceived spatial separation of the components of the tone complex across the two tone tasks, the separability judgment ratings and the ear dominance scores were not correlated for either tone task. A significant correlation, however, was evidenced between the laterality measure for speech and the judgment of separability, indicating that a REA of increased magnitude is associated with more clearly localized and spatially separate speech sounds. Finally, the dominance scores on the two tone tasks were uncorrelated with the laterality measures of the speech task, whereas the scores on the tone tasks were highly correlated. The results suggest that spatial complexity does play a role in the emergence of the REA for speech. However, the failure to find a relationship between speech and nonspeech tasks suggest that all perceptual asymmetries observed with dichotic stimuli cannot be accounted for by a single theoretical explanation.     

Adolescent girls' sex role development: Relationship with sports participation,self-esteem,and age at menarche

This study investigated the development of sex role orientation among adolescent girls, and explored its relationship with sports participation, self-esteem, and age at menarche. The instruments were administered to 134 girls yearly from Grades 6 to 10 (ages 11 to 15). The results obtained with the Bem Sex Role Inventory showed group mean increases in the masculine and feminine scale scores, and considerable shifting in sex role categorizations over the five years. However, individual differences were quite consistent during the five-year study, suggesting some degree of stability in sex role orientation during adolescence. Sports participants and girls with high self-esteem had greater masculine sex role orientations throughout adolescence, with no differences in feminine orientations. It was concluded that the relationship of sex role orientation with sports participation and self-esteem was not an interactive one, but was reflective of individual differences. These individual differences begin in late childhood, with the variables developing concurrently. Age at menarche did not affect sex role orientation.
