Demography, psychosocial factors, and emotional problems of Korean American adolescents

This study attempted to identify emotional problems and examine the related demographic and psychosocial factors of 340 Korean American adolescents in a major metropolitan area. Results revealed that lower GPA, longer length of residence in the United States, subjects' poor self-esteem, greater severity of conflict with parents, and poor relationships with peers were significant predictors of emotional problems. The findings could be beneficial for social work practitioners and educators in determining the service needs of Korean American adoelscents and designing interventions for their problems.     

Age-related differences in the brain areas outside the classical language areas among adults using category decision task

Older adults perform much like younger adults on language. This similar level of performance, however, may come about through different underlying brain processes. In the present study, we evaluated age-related differences in the brain areas outside the typical language areas among adults using a category decision task. Our results showed that similar activation patterns were found in classical language processing areas across the three age groups although regional lateralization indices in Broca’s and Wernicke’s areas decreased with age. The greatest differences, however, among the three groups were found primarily in the brain areas not associated with core language functioning including the hippocampus, middle frontal gyrus, ventromedial frontal cortex, medial superior parietal cortex and posterior cingulate cortex. Therefore, the non-classical language areas may exhibit an age-related difference between three age groups while the subjects show a similar activation pattern in the core, primary language processing during a semantic decision task.     

Additive Multilevel Item Structure Models with Random Residuals: Item Modeling for Explanation and Item Generation

An additive multilevel item structure (AMIS) model with random residuals is proposed. The model includes multilevel latent regressions of item discrimination and item difficulty parameters on covariates at both item and item category levels with random residuals at both levels. The AMIS model is useful for explanation purposes and also for prediction purposes as in an item generation context. The parameters can be estimated with an alternating imputation posterior algorithm that makes use of adaptive quadrature, and the performance of this algorithm is evaluated in a simulation study.     

Living in the north is not necessarily favorable: Different metaphoric associations between cardinal direction and valence in Hong Kong and in the United States

The Conceptual Metaphor Theory (e.g., Lakoff & Johnson, 1980 ) suggests that people represent abstract concepts in terms of concrete concepts via metaphoric association. Participants in the United States (US) showed that cardinal direction (north/south) is metaphorically associated with valence (positive/negative), as reflected by their estimate for where a person with high or low socioeconomic status (SES) lives in a fictional city or their own living preference (Meier, Moller, Chen, & Riemer‐Peltz, 2011 ). The present study tested whether the cardinal direction–valence metaphoric association could be moderated by cultural differences. Although US participants believed that high‐SES and low‐SES individuals were more likely to live in the northern and southern part of the city, respectively, the reverse was so for Hong Kong (HK) participants (Study 1). When asked where they themselves would like to live, HK participants preferred to live in a southern area, whereas US participants showed no preference (Studies 2 and 3). These findings demonstrate cultural differences in metaphoric associations between cardinal direction and valence for HK and US participants. Copyright © 2014 John Wiley & Sons, Ltd.     

Rediscovering the Positive Psychology of Sport Participation: Happiness in a Ski Resort Context

Interrelated functions of the three orientations to happiness were examined by a cross-sectional survey, in the context of a ski resort experience. Accordingly, a conceptual framework of pleasure, flow, and involvement influencing satisfaction was established. Utilizing structural equation modeling, the conceptual framework was tested by analyzing data collected from 279 participants who enjoyed skiing and/or snowboarding. Results from bootstrap test indicated that direct and total effects from flow had the highest predictive power on satisfaction. In contrast, pleasure showed higher explanatory power on subjective experiences of flow and meaning, and influenced satisfaction only by indirect effects through those elements. Together, these findings support the research model synthesizing the behavioral constructs of sport participation with subjective well-being perspectives. Moreover, the expanded model in a sporting context further evidences the functional roles of the orientations to happiness by results consistent with extant literature of positive psychology. Roles of embodiments of orientations to happiness in an action-based exercise and its implications are further discussed.     

Genetic Testing of Children for Predisposition to Mood Disorders: Anticipating the Clinical Issues

Large-scale sequencing information may provide a basis for genetic tests for predisposition to common disorders. In this study, participants in the Coriell Personalized Medicine Collaborative (N?=?53) with a personal and/or family history of Major Depressive Disorder or Bipolar Disorder were interviewed based on the Health Belief Model around hypothetical intention to test one’s children for probability of developing a mood disorder. Most participants (87 %) were interested in a hypothetical test for children that had high (“90 %”) positive predictive value, while 51 % of participants remained interested in a modestly predictive test (“20 %”). Interest was driven by beliefs about effects of test results on parenting behaviors and on discrimination. Most participants favored testing before adolescence (64 %), and were reluctant to share results with asymptomatic children before adulthood. Participants anticipated both positive and negative effects of testing on parental treatment and on children’s self-esteem. Further investigation will determine whether these findings will generalize to other complex disorders for which early intervention is possible but not clearly demonstrated to improve outcomes. More information is also needed about the effects of childhood genetic testing and sharing of results on parent–child relationships, and about the role of the child in the decision-making process.     

Demographic and Experiential Correlates of Public Attitudes Towards Cell-Free Fetal DNA Screening

This study seeks to inform clinical application of cell-free fetal DNA (cffDNA) screening as a novel method for prenatal trisomy detection by investigating public attitudes towards this technology and demographic and experiential characteristics related to these attitudes. Two versions of a 25-item survey assessing interest in cffDNA and existing first-trimester combined screening for either trisomy 13 and 18 or trisomy 21 were distributed among 3,164 members of the United States public. Logistic regression was performed to determine variables predictive of interest in screening options. Approximately 47 % of respondents expressed an interest in cffDNA screening for trisomy 13, 18, and 21, with a majority interested in cffDNA screening as a stand-alone technique. A significantly greater percent would consider termination of pregnancy following a diagnosis of trisomy 13 or 18 (52 %) over one of trisomy 21 (44 %). Willingness to consider abortion of an affected pregnancy was the strongest correlate to interest in both cffDNA and first-trimester combined screening, although markedly more respondents expressed an interest in some form of screening (69 % and 71 %, respectively) than would consider termination. Greater educational attainment, higher income, and insurance coverage predicted interest in cffDNA screening; stronger religious identification also corresponded to decreased interest. Prior experience with disability and genetic testing was associated with increased interest in cffDNA screening. Several of these factors, in addition to advanced age and Asian race, were, in turn, predictive of respondents’ increased willingness to consider post-diagnosis termination of pregnancy. In conclusion, divergent attitudes towards cffDNA screening—and prenatal options more generally – appear correlated with individual socioeconomic and religious backgrounds and experiences with disability and genetic testing. Clinical implementation and counseling for novel prenatal technologies should take these diverse stakeholder values into consideration.     

Organizational identification and perceived organizational support as mediators of the procedural justice–citizenship behaviour relationship: A cross-cultural constructive replication

This study examined the psychological processes that might underlie the relationship between procedural justice and organizational citizenship behaviour using an integrative approach. In doing so, we focused on the mediating effects of perceived organizational support and organizational identification in the relationship simultaneously. Framed as an integrated test of social exchange and social identity predictions, the hypotheses were tested using two cross-cultural samples (i.e., South Korea and the United States) as well as different operationalizations of the constructs of interest, which meets the criterion of a constructive replication (Lykken, 1968 Lykken, D. 1968. Statistical significance in psychological research. Psychological Bulletin, 70: 151–159. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) by two samples (N = 130, 135). Interestingly, the results showed convergence in support of the mediating role of organizational identification, but not perceived organizational support, when the two mediators were included in the model concurrently. These findings indicate that social identity may be the dominant psychological mechanism underlying the relationship between procedural justice and organizational citizenship behaviour in workplaces.
