Self-Perceived Health among School-Aged Adolescents: a School-Based Study in Southern Brazil

This study identified which aspects regarding the dimensions of quality of life, in terms of body image, relationships with family and friends, rest and free time, school, well-being and lifestyles function as predictors of self-perceived health among school adolescents in the southern Brazil. The sample was composed of 3360 students, ninth graders in public schools in the metropolitan area of Porto Alegre/RS (Brazil). The instruments used were: a) Health Behaviour in School Children, b) Happiness Overall Life, c) Positive and Negative Affect Scale, d) General Health Questionnaire (GHQ-12), e) Brief Multidimensional Scale of Life Satisfaction in Students (BMSLSS), and f) Subscale of Cohesion of the Family Environment Scale (FES). Multiple linear regression analysis was conducted to identify the predictors of perceived health. The results revealed a model with nine predictor variables in the sense that being more satisfied with one’s own body, perceiving one’s eating habits as healthier compared to others of the same age, having a greater sense of happiness in their current life, being able to talk to one’s brothers/sisters about issues of concern, a perception of being thinner compared to other people of the same age, greater consumption of healthy food, greater presence of positive affects and being male contribute to a greater perception of health. The results show that, for this population, the health issues are beyond the concern over physical health or the presence or absence of symptoms, but also encompass behavioral, relational and psychological aspects, as well.

     

Career Happiness Among Asian Americans: The Interplay Between Individualism and Interdependence

Career happiness is reexamined for relevance to non‐Western cultures. Joseph Campbell's (1968, 1972, 1988) interpretations of myth are reviewed for individualistic vs. interdependent themes and critiqued in light of Asian American vocational concerns, with examples from Chinese culture. Counselors are encouraged to reflect cultural sensitivity and understanding through collectivist interpretations of mythological archetypes and metaphors. La felicidad de la carrera se reconsidera para la aplicabilidad a culturas no‐occidentales. Las interpretaciones de Joseph Campbell (1968, 1972, 1988) del mito se revisan para individualista vs. temas interdependientes y critican en relación a Asiático Americano preocupación vocacional, con ejemplos de la cultura china. Los consejeros son alentados a reflejar la sensibilidad cultural y el entendimiento por interpretaciones colectivistas de arquetipos y metáforas mitológicos.     

Treatment with medications affecting dopaminergic and serotonergic mechanisms: effects on fluency and anxiety in persons who stutter

Medications with dopamine antagonist properties, such as haloperidol, and those with serotonin reuptake inhibitor properties, such as clomipramine, have been shown to improve fluency. To examine the degree to which each of these two pharmacological mechanisms might independently affect fluency, a selective serotonin reuptake inhibitor, paroxetine, and a selective dopamine (D-2) antagonist, pimozide, were evaluated. Both types of medications also affect mood and anxiety, factors that could influence fluency levels. Therefore, we also evaluated the medications’ effects on generalized and speech-related anxiety and the relationships between changes in anxiety and changes in fluency in 11 subjects with a history of developmental stuttering. The randomized, double blind, placebo-controlled crossover study that was designed had to be terminated prior to completion due to severe side effects following withdrawal from paroxetine. Even with a reduced sample size (n = 6), significant improvement in percent fluent speaking time (p = 0.02) was found using a telephone task between baseline and pimozide (n = 6), with average duration of dysfluencies significantly shorter (p = 0.04) but no significant difference in the estimated number of dysfluencies per minute. This significant improvement was associated with non-significant increases in generalized anxiety, but non-significant decreases in speech-related anxiety. No significant differences were found in fluency between baseline and paroxetine (n = 5). These preliminary results suggest that fluency improvement is more likely to be mediated by dopaminergic rather than serotonergic mechanisms. Due to its side effects, however, pimozide may be considered a risk for treatment of stuttering.

Educational objectives: As a result of reading this paper the reader will describe and explain: (1) how medications may affect fluency and the rationale for selecting medications for treatment trials; (2) the interrelationship between fluency and anxiety; and (3) factors important in developing clinical trials using medications.     

Access to Child and Adolescent Mental Health Services

Adequate access to child and adolescent mental health services for young people in high need populations is an important concern of service systems researchers and program evaluators. We present results of a statewide study of access to community mental health services for eight populations of special concern. The analysis relied exclusively on existing databases in conjunction with innovative statistical techniques to provide comprehensive measures of access to care. Our findings indicate that access to care varied substantially across special populations, although children and adolescents in each of our eight “special populations” had greater access to public mental health services than members of the general population of the state. The interpretation of the findings and directions for future research are discussed.     

Relative contributions of perceived mattering to parents and friends in predicting adolescents' psychological well-being

Perceived mattering is the psychological tendency to perceive the self as significant to specific other people. The central goal of this study was to examine whether adolescents' perceived mattering across social spheres (parents and friends) is addtive or compensatory in predicting adolescents' psychological well-being. Tests of the relative importance of adolescents' perceived mattering to parents and friends for psychological well-being were conducted using data from two convenience samples. Study 1 participants were, on the average, 17.5 yr. old and living in rural northwestern United States (N=128, 50% male, n=64; 50% female, n=64). Study 2 participants, on the average, were 16.9 yr. old, from a suburban western Canadian region (N=532, 51.4% male, n=273; 48.6% female, n=259). Hierarchical regression analysed with indicators of self-concept and behavioral misconduct as dependent variables used perceived mattering to parents and perceived mattering to friends and the interaction between these two variables as independent variables. Perceived mattering in both social spheres seemed the optimal condition for adolescents. Perceived mattering to friends "added" to perceived mattering to parents in explaining variance in assessments of psychological well-being in both studies.     

Lesion analysis of the brain areas involved in language comprehension

The cortical regions of the brain traditionally associated with the comprehension of language are Wernicke's area and Broca's area. However, recent evidence suggests that other brain regions might also be involved in this complex process. This paper describes the opportunity to evaluate a large number of brain-injured patients to determine which lesioned brain areas might affect language comprehension. Sixty-four chronic left hemisphere stroke patients were evaluated on 11 subtests of the Curtiss-Yamada Comprehensive Language Evaluation - Receptive (CYCLE-R; Curtiss, S., & Yamada, J. (1988). Curtiss-Yamada Comprehensive Language Evaluation. Unpublished test, UCLA). Eight right hemisphere stroke patients and 15 neurologically normal older controls also participated. Patients were required to select a single line drawing from an array of three or four choices that best depicted the content of an auditorily-presented sentence. Patients' lesions obtained from structural neuroimaging were reconstructed onto templates and entered into a voxel-based lesion-symptom mapping (VLSM; Bates, E., Wilson, S., Saygin, A. P., Dick, F., Sereno, M., Knight, R. T., & Dronkers, N. F. (2003). Voxel-based lesion-symptom mapping. Nature Neuroscience, 6(5), 448-450.) analysis along with the behavioral data. VLSM is a brain-behavior mapping technique that evaluates the relationships between areas of injury and behavioral performance in all patients on a voxel-by-voxel basis, similar to the analysis of functional neuroimaging data. Results indicated that lesions to five left hemisphere brain regions affected performance on the CYCLE-R, including the posterior middle temporal gyrus and underlying white matter, the anterior superior temporal gyrus, the superior temporal sulcus and angular gyrus, mid-frontal cortex in Brodmann's area 46, and Brodmann's area 47 of the inferior frontal gyrus. Lesions to Broca's and Wernicke's areas were not found to significantly alter language comprehension on this particular measure. Further analysis suggested that the middle temporal gyrus may be more important for comprehension at the word level, while the other regions may play a greater role at the level of the sentence. These results are consistent with those seen in recent functional neuroimaging studies and offer complementary data in the effort to understand the brain areas underlying language comprehension.     

Perinatal exposure to diethylstilbestrol improves olfactory discrimination learning in male and female Swiss-Webster mice

During late prenatal and early postnatal brain development, estrogen induces structural sex differences that correspond to behavioral differences in certain domains such as learning and memory. The typically superior performance of males is attributed to the action of elevated concentrations of estrogen, derived inside neurons from the aromatization of testosterone. In contrast, female performance appears dependent on minimal estrogenic activity. Rat models of the relationship between hormones and cognitive behavior predominate the field, but the advent of genetically modified mice as research tools necessitates development of analogous mouse models. This study examined how early postnatal exposure to the synthetic estrogen diethylstilbestrol (DES) affected the ability of male and female Swiss-Webster mice to learn a two-choice olfactory discrimination and three repeated reversals. Mice treated with subcutaneous injections of DES from postnatal days 1-10 learned reversals more readily than oil-treated controls, a difference that became evident after repeated testing. DES-exposed males and females learned reversals at a comparable rate, suggesting that early postnatal estrogen exposure does not influence this mode of learning through a sexually differentiated mechanism in mice. An analysis of response patterns during qualitatively different phases of reversal learning revealed that DES-induced improvements probably were not due to greater inhibitory control. Instead, DES appeared to enhance associative ability. Early postnatal estrogen exposure may have the potential to preserve certain cognitive skills in adulthood.     

Religious involvement and the forgiving personality

The relationship between religious involvement and forgiveness was assessed in three samples of Western Europeans living in a social environment dominated by the Catholic tradition. The samples comprised nonbelievers/nonattendees, believers/nonattendees, believers/regular attendees, and religious people. Age and religious involvement were shown to affect the willingness to forgive in an interactive way: The effect of religious involvement was stronger for the elderly group. We also found that what made the difference in the willingness to forgive was mainly the social commitment to religion (attendance in church and the taking of vows), not mere personal beliefs. In addition, age and religious involvement were found to affect blockage towards forgiveness in an additive way.
