A cross-cultural study of the structure of comorbidity among common psychopathological syndromes in the general health care setting

This study presents analyses of 7 common psychopathological syndromes in the World Health Organization (WHO) Collaborative Study of Psychological Problems in General Health Care (T. B. Ustun & N. Sartorius, 1995). Data on depression, somatization, hypochondriasis, neurasthenia, anxious worry, anxious arousal, and hazardous use of alcohol were analyzed for 14 countries (Ns for each country ranged from 196 to 800). Four models were evaluated: a 1-factor model; a 2-factor model in which all syndromes except hazardous use of alcohol represented internalizing problems; and two 3-factor models. The 2-factor model fit best. These results extend previous research on the 2-factor model to the current complaints of attendees of general health care clinics, to a new set of syndromes, and to a variety of both Western and non-Western countries.     

Ethnic, gender, and socioeconomic differences in young adults' self-disclosure: who discloses what and to whom?

Self-disclosure of feelings, thoughts, experiences, and beliefs is central to our lives as social beings and has numerous implications for relationships and health. Although prior research suggests that men and underrepresented groups disclose less, ethnicity is conflated with socioeconomic status and there are few data regarding the types of information that different groups disclose and whether this information is disclosed equally to different people. The current study measured self-disclosure in 203 young adults (50% African American, 50% female), in respect of seven domains and 10 interpersonal targets. As expected, disclosure was not lower among African Americans once income was controlled, although both ethnicity and gender interacted with domain of disclosure and interpersonal target. Importantly, young men and African Americans reported disclosing less in the context of more intimate relationships. Together, these results suggest that income may be as important in predicting low disclosure as ethnicity or gender and that lower disclosure in low-disclosing groups is particularly evident in intimate relationships. Results are discussed in terms of their implications for patterns of interpersonal relating and physical and mental health processes.     

Gender differences in emotional response among European Americans and Hmong Americans

The present study examined the effects of gender on the emotional responses (physiology, self-reports of emotion, and emotional facial behaviour) of European Americans (EA) and Hmong Americans (HA) while they relived past emotional events. Women were more emotionally reactive than men: They demonstrated greater changes in electrodermal reactivity overall, reported experiencing more intense emotion while reliving anger and love, and smiled more while reliving happiness and love. The pattern and magnitude of these differences were similar for EA and HA, suggesting that to some degree, the effects of gender on emotional response may hold across ethnic groups.     

De/geneticizing Caste: Population Genetic Research in South Asia

Recent years have witnessed a number of population genetics studies aiming to explore the ‘genetic profile’ of the South Asian population and of the caste system. This paper examines four genetic studies and their mass media representations, and discusses interviews with leading historians and social scientists whose work has focused on issues of the caste system. Similar to earlier commentators—from colonial scholars and administrators to Hindu reformers and nationalists—who provided different explanations for the origin of the caste system, recent genetic studies have offered conflicting inferences on the nature of castes and tribes of the subcontinent. These studies, the way they were received on the subcontinent, and assayed by historians of caste, tell a story about agendas of geneticization competing with forces of resistance. On the one hand, they signal a new interest in the debate about the relationship between caste and ‘ethnicity’; on the other hand, they are used selectively by different social groups to strengthen their own political agendas, are denied cognitive validity by historians of caste, and never reach a consensus about the history of caste formation.     

Internet-addicted kids and South Korean government efforts: boot-camp case

Computer overuse has been a serious problem for the past several years. One aspect of the information age has been the novel concerns deriving from advanced IT technology--which include Internet addiction, gambling, and so on. These Internet-based problems have emerged in many countries, including South Korea. In an effort to solve this problem, the South Korean government has created a variety of programs designed to cure teenagers' Internet addictions, most notably the Jump Up Internet Rescue School, a camp designed to cure Internet-addicted or online game-addicted children. In this study, we review this boot-camp program and present a brief review of the literature concerning Internet addiction and habit theory. Additionally, we provide some useful implications for the Korean government and other countries, practitioners, and researchers. It is also anticipated that the findings from this study will provide us with a better understanding of how case-study-based research into Internet addiction curative programs can be regarded as a burgeoning field of Internet-related research.     

Nothing But Stereotypes? Negligible Sex Differences Across Creativity Measures in Science,Arts, and Sports Adolescent High Achievers

Previous research has focused on understanding when, why, and how sex differences in creativity occur, as results vary across samples, measures, and methodologies. In the current study we investigated sex differences in creativity among 984 high achieving adolescents in three expertise areas: Sciences, Arts, and Sports. Eight creativity indicators were analyzed: Alternative uses task (AUT) fluency; creative self-efficacy (CSE); intraindividual strengths (difference between CSE and AUT Fluency); five self-reported creativity scales: Self/everyday, scholarly, performance, mechanical/scientific, artistic. The results showed negligible sex differences ( $n_{\mathrm{p}}^2$ = .01), with females performing better in AUT Fluency and males self-rating their CSE higher. No sex differences were found in self/everyday, scholarly and performance creativity. Males self-rated their mechanical/scientific creativity ( $n_{\mathrm{p}}^2$ = .06) higher than females; while females self-rated their artistic creativity ( $n_{\mathrm{p}}^2$ = .02) higher in comparison to males. Our results extend the existing literature by finding negligible sex differences in adolescent expert groups. However, some stereotypical differences emerged, for example, females with Sciences expertise rated their mechanical/scientific creativity lower than males with and even without Sciences expertise. Results call for further investigation into the links between sex differences, expertise, and specific creativity domains.     

More Than Just IQ: School Achievement Is Predicted by Self-Perceived Abilities—But for Genetic Rather Than Environmental Reasons

ABSTRACT— Evidence suggests that children's self-perceptions of their abilities predict their school achievement even after one accounts for their tested cognitive ability (IQ). However, the roles of nature and nurture in the association between school achievement and self-perceived abilities (SPAs), independent of IQ, is unknown. Here we reveal that there are substantial genetic influences on SPAs and that there is genetic covariance between SPAs and achievement independent of IQ. Although it has been assumed that the origins of SPAs are environmental, this first genetic analysis of SPAs yielded a heritability of 51% in a sample of 3,785 pairs of twins, whereas shared environment accounted for only 2% of the variance in SPAs. Moreover, multivariate genetic analyses indicated that SPAs predict school achievement independently of IQ for genetic rather than environmental reasons. It should therefore be possible to identify "SPA genes" that predict school achievement independently of "IQ genes."     

Exploring the cognitive development of children born to adolescent mothers in South Africa

This study explores the cognitive development of children born to adolescent mothers within South Africa compared to existing reference data, and explores development by child age bands to examine relative levels of development. Cross-sectional analyses present data from 954 adolescents (10–19 years) and their first-born children (0–68 months). All adolescents completed questionnaires relating to themselves and their children, and standardized child cognitive assessments (Mullen Scales of Early Learning) were undertaken. Cognitive development scores of the sample were lower than USA reference population scores and relative performance compared to the reference population was found to decline with increasing child age. When compared to children born to adult mothers in the sub-Saharan African region, children born to adolescent mothers (human immunodeficiency virus [HIV] unexposed; n = 724) were found to have lower cognitive development scores. Findings identify critical periods of development where intervention may be required to bolster outcomes for children born to adolescent mothers.

Highlights

• An exploration of the cognitive development of children born to adolescent mothers within South Africa utilizing the Mullen Scales of Early Learning.
• Cognitive development scores of children born to adolescent mothers within South Africa were lower compared to USA norm reference data and declined with child age.
• Previous studies utilizing the Mullen Scales of Early Learning within sub-Saharan Africa were summarized, and comparisons were made with the current sample.
• Findings highlight a potential risk of developmental delay among children born to adolescent mothers compared to children of adult mothers in the sub-Saharan African region.
