Machismo continues to be a defining aspect of Mexican American men that informs a wide array of psychological and behavioral dimensions. Although strides have been made in this area of research, understanding of the role of this construct in the lives of gay men remains incomplete. Our purpose in this study was to gain a deeper understanding of machismo using a sample of Mexican American gay men. This study examined for the first time whether a 2-factor model of machismo previously validated with heterosexual, Mexican American men generalized to a sample of 152 gay men of similar ethnic background. Relations between machismo, sexual risk, and internalized homophobia were also explored. Confirmatory factor analysis supported the 2-factor model with the current sample. Results also indicated machismo as predicting internalized homophobia and as an index of risky sex. Limitations are presented and implications are discussed.  相似文献

This review covers research on the negative effects of prenatal depression and cortisol on fetal growth, prematurity and low birthweight. Although prenatal depression and cortisol were typically measured at around 20 weeks gestation, other research suggests the stability of depression and cortisol levels across pregnancy. Women with Dysthymia as compared to Major Depression Disorder had higher cortisol levels, and their newborns had lower gestational age and birthweight. The cortisol effects in these studies were unfortunately confounded by low serotonin and low dopamine levels which in themselves could contribute to non-optimal pregnancy outcomes. The negative effects of depression and cortisol were also potentially confounded by comorbid anxiety, by demographic factors including younger age, less education and lower SES of the mothers and by the absence of a partner or a partner who was unhappy about the pregnancy or a partner who was depressed. Substance use (especially caffeine use) was still another risk factor. All of these problems including prenatal depression, elevated cortisol, prematurity and low birthweight and even postpartum depression have been reduced by prenatal massage therapy provided by the women's partners. Massage therapy combined with group interpersonal psychotherapy was also effective for reducing depression and cortisol levels. Several limitations of these studies were noted and suggestions for future research included exploring other predictor variables like progesterone/estriol ratios, immune factors and genetic determinants. Further research is needed both on the potential use of cortisol as a screening measure and the use of other therapies that might reduce prenatal depression and cortisol in the women and prematurity and low birthweight in their infants.  相似文献

The purpose of this study was to examine the effectiveness of second tier intervention at-risk readers within the context of a Response to Intervention approach. The study was conducted in the Canary Islands (Spain), directed by research team ¨Dificultades de Aprendizaje, Psicolingüística y Nuevas Tecnologías¨ (DEA&NT) from University of La Laguna, and supported by the Government of the Canary Islands. A sample of 1.123 Spanish children from fourteen schools districts were given the Spanish adaptation of The Hong Kong Specific Learning Difficulties Behavior Checklist and children who scored at or above the 75th percentile on the test were classified as "at risk" for early reading difficulties. Half of the students were randomly assigned to a project-based intervention condition where they received small group supplementary intervention for 30 minutes daily using the Prevención de las Dificultades Específicas de Aprendizaje (PREDEA) curriculum from mid to late December and continued until mid June. The other half received whatever remedial services were available at their schools. Results indicated that children who received the PREDEA curriculum had higher scores on the Early Grade Reading Assessment Test (EGRA) on initial sound identification, listening comprehension, letter sound knowledge and oral reading fluency compared to the control group.  相似文献

The goal of this research is to describe the visual search patterns for diverse traffic signs. Twelve drivers of both genders and different driving experience levels took part in real driving research with an instrumented car provided with an eye-tracking system. Looking at signs has a weak relation with speed reduction in cases where actual driving speed was higher. Nevertheless, among the people who looked at the sign, the percentage of those who reduce the speed below the limit is greater than of those who do not look at the sign. Guide traffic signs, particularly those mounted over the road, are more frequently glanced at than speed limit signs, with a glance duration of more than one second, in sequences of more than two consecutive fixations. Implications for driving and the possibilities and limitations of eye movement analysis for traffic sign research are discussed.  相似文献

The present study considers the importance of analyzing what very powerful or influential people think about their employees. We assumed that belonging to a specific category has a differential effect on the perception of others' thoughts in the organization ("meta-representation"). Therefore, experts in organization and human resources from diverse organizations and institutions assessed seven dimensions which structure the organizational image (context, structure, organizational processes, working climate, culture, satisfaction and efficacy). The results showed that belonging to a group (managers or leaders, academicians, consultants, technicians or employees' representatives) modulated the meta-representation, as the experts' opinion about what they think that the employees consider important was related to their group. This was specifically the case for the managers' and leaders' representations, which differed from the other groups and especially from that of the technicians and employees' representatives. The implications of the present findings are discussed.  相似文献

There are few studies on the development of anxiety and depression in orthopaedics and trauma (O&T) inpatients. We designed a cross-sectional study aimed at comparing the prevalence of depression and anxiety in 100 O&T inpatients and 100 clinical inpatients in the same hospital. O&T patients were divided into subgroups: trauma and non-trauma (arthroplasty, tumour, and infection sub grouping). We measured anxiety and depression by the Hospital Anxiety and Depression Scale and co-morbidities by the Charlson age-adjusted comorbidity index (CCI). For the trauma subgroup, AO/OTA fracture classification and Gustillo and Anderson grade of open fractures classification was applied. The prevalence of anxiety and depression was 35% and 28%, respectively for the clinical sample, and 44% and 33% for the O&T sample. Compared with the clinical sample, anxiety scores were higher in the O&T sample (p = .047), and in arthroplasty (p = .020) and trauma subgroups (p = .031). In the O&T sample, high CCI scores were associated with high anxiety scores (p = .033).  相似文献

We studied the capacity of post-training intracranial self-stimulation (SS) to reverse or ameliorate learning and memory impairments caused by amygdala damage in rats. A first experiment showed that lesions of the basolateral amygdala (BLA) slow down acquisition of two-way active avoidance conditioning (2wAA). In a second experiment we observed that a post-training SS treatment administered immediately after each 2wAA conditioning session is able to completely reverse the disruptive effects of the BLA lesions, and the facilitative effect lasts for 10 days. A third experiment allowed us to differentiate the strong recuperative effects of the SS treatment from the slight effect caused by overtraining the same conditioning response. We concluded that SS is able to counteract the behavioral deficit induced by BLA damage, probably by activating alternative undamaged brain structures related to learning and memory, such as the hippocampus.  相似文献

Depressed pregnant women were classified as dysthymic or major depression disorder based on the Structured Clinical Interview for Depression and followed to the newborn period. The newborns of dysthymic versus major depression disorder mothers had a significantly shorter gestational age, a lower birthweight, shorter birth length and less optimal obstetric complications scores. The neonates of dysthymic mothers also had lower orientation and motor scores and more depressive symptoms on the Brazelton Neonatal Behavioral Assessment Scale. These findings were not surprising given the elevated cortisol levels and the inferior fetal measures including lower fetal weight, fetal length, femur length and abdominal circumference noted in our earlier study on fetuses of dysthymic pregnant women.  相似文献

Although online psychological services and research based on them are increasing rapidly, it is not that easy to find investigations that focus on the kind of people that demand them. To know their profile could help to improve the online psychological services that are offered to them. For this purpose, we analysed the sociodemographic characteristics of 1052 participants, all of them having posed a psychological question to our online advice service. The relations between sociodemographics and variables related to the psychological consultation are analysed herein. Features such as age distribution, a high proportion of long-term problems, the large quantity of questions from Latin America, or the under representation of the lowest socioeconomic and educational levels could lead to clinical, social and legal implications that we comment on in this work.  相似文献
