To Balance or not to Balance: Confirmatory Factor Analysis of the Affect-Balance Scale

This study examined the psychometric quality of the Affect-Balance Scale (ABS) (Bradburn, 1969) using data collected from 292 middle-aged and older adults, living independently. The dimensionality of the scale was examined, the quality of individual items was tested, and the validity of the ABS was studied. Using a tetrachoric correlation matrix with the robust weighted least squares (WLSMV) estimation method of the Mplus program, we found that two moderately correlated (r = -0.37) constructs are needed to adequately account for the pattern of item scores in the ABS. Two of the 10 ABS items were found to be problematic. When raw sum scores were used in analysis, the correlation between the positive-affect and the negative-affect subscales was lower (r = -0.17), indicating that random and nonrandom measurement error masked the relationship between the two. While affect-balance correlated substantially with five criterion well-being measures, the negative-affect subscale (which constitutes half of the ABS) had a similar pattern of correlations, with only slightly lower magnitude. The theoretical construct of nobreak 'balance' is also questioned. The 'balance' scoring method (subtracting the negative-affect subscale score from the positive-affect subscale score) nets exactly the same score as does summing scores from both subscales together. Accordingly, the summed scores have the very same correlations with other variables as do the balance scores.     

Structure and Etiology of Co-occurring Internalizing and Externalizing Disorders in Adolescents

Several studies suggest that a two-factor model positing internalizing and externalizing factors explains the interrelationships among psychiatric disorders. However, it is unclear whether the covariation between internalizing and externalizing disorders is due to common genetic or environmental influences. We examined whether a model positing two latent factors, internalizing and externalizing, explained the interrelationships among six psychiatric disorders (major depressive disorder, generalized anxiety disorder, separation anxiety disorder, attention-deficit/hyperactivity disorder, oppositional defiant disorder, and conduct disorder) in adolescents, and whether there are common genetic and environmental influences on internalizing and externalizing latent factors. Multivariate behavior genetic analyses of data from 1162 twin pairs and 426 siblings ascertained from the general population via the Colorado Center for Antisocial Drug Dependence (CADD) were conducted. We found support for a model positing two latent factors (internalizing and externalizing). These factors were moderately heritable and influenced by significant common genetic and nonshared environmental influences. These findings suggest that co-occurrence of internalizing and externalizing psychopathology in adolescents results from both genetic and environmental influences.     

The Relationship Between Creativity and Behavior Problems Among Underachieving Elementary and High School Students

Understanding the role creative potential may play in the underachievement of some students could help schools and parents understand underachievers. This study examined whether there is a relationship between creativity and behavior problems among underachievers. Forty-one elementary and 89 high school students and 4 teachers in Korea participated in this study. The principal study involved comparing all of the students' scores on the 3 measures of creative potential (Torrance Tests of Creative Thinking-Figural [TTCT], Runco Ideational Behavior Scale [RIBS], and Scales for Rating the Behavioral Characteristics of Superior Students-Revised Edition [SRBCSS-R]), with their scores on a measure of behavior problems reported by their teachers. The results indicated that, among underachievers, there is a relationship between behavioral problems and students' scores on the 3 measures of creative potential. An understanding of these students and their behavior will help us promote creative students' academic and lifelong success in classrooms.     

Underachievement and Creativity: Are Gifted Underachievers Highly Creative?

This literature review synthesizes the available literature that suggests that the underachievement of gifted students may be tied to their inherent and unrecognized creativity. Apparently, many gifted students are underachievers and up to 30% of high school dropouts may be highly gifted. Beginning with the belief that these gifted underachievers may be highly creative, this article first reviews the view that creativity can be a gift, much like intelligence. It then reviews the typical characteristics of gifted underachievers and the similar characteristics of creative underachievers. Finally, it reviews the studies and theories that have shown that once underachievers are placed in an environment that fosters their needs, with motivation, mentors, understanding, freedom, and responsibility, they can become highly productive. Classrooms across the nation are facing ever-increasing pressure to educate every child, especially with the No Child Left Behind (2007) Act. There is a demand for those children who might normally “fall through the cracks” to receive closer attention and potentially greater accommodations than were previously required.     

Creativity and Confucianism Among American and Korean Educators

The purpose of this study was to examine differences in creative styles and Confucian ideas between Koreans and Americans and to examine the relationship between creativity and Confucianism. A total number of 579 educators (227 American and 352 Korean) participated in this study. Eastern-Western Perspective Scale was used to measure participants’ level of Confucianism and the Torrance Tests of Creative Thinking-Figural was used to measure participants’ level of creative potential. The results indicate that Koreans have strikingly more Confucian ideals than Americans, whereas Americans have more creative strengths and are more adaptively creative than Koreans. The results also indicate higher levels of Confucianism relate to lower levels of creativity. The Confucian elements that show negative relationships with creativity are suppression of expression, gender inequality, gender role expectations, and filial piety.     

Personality Dimensions as Common and Broadband-Specific Features for Internalizing and Externalizing Disorders

Several researchers have suggested that the nature of the covariation between internalizing and externalizing disorders may be understood better by examining the associations between temperament or personality and these disorders. The present study examined neuroticism as a potential common feature underlying both internalizing and externalizing disorders and novelty seeking as a potential broad-band specific feature influencing externalizing disorders alone. Participants were 12- to 18-year-old twin pairs (635 monozygotic twin pairs and 691 dizygotic twin pairs; 48 % male and 52 % female) recruited from the Colorado Center for Antisocial Drug Dependence. Genetic and nonshared environmental influences shared in common with neuroticism influenced the covariation among distinct internalizing disorders, the covariation among distinct externalizing disorders, and the covariation between internalizing and externalizing disorders. Genetic influences shared in common with novelty seeking influenced the covariation among externalizing disorders and the covariation between major depressive disorder and externalizing disorders, but not the covariation among internalizing disorders or between anxiety disorders and externalizing disorders. Also, after accounting for genetic and environmental influences shared in common with neuroticism and novelty seeking, there were no significant common genetic or environmental influences among the disorders examined, suggesting that the covariance among the disorders is sufficiently explained by neuroticism and novelty seeking. We conclude that neuroticism is a heritable common feature of both internalizing disorders and externalizing disorders, and that novelty seeking is a heritable broad-band specific factor that distinguishes anxiety disorders from externalizing disorders.     

Dislocation multiplication in bcc molybdenum: A dislocation dynamics simulation

Plastic deformation of Mo single crystals is examined by direct simulation of dislocation dynamics under stress. Initial dislocation populations are made to mimic real dislocation microstructures observed in transmission electron microscopy cross-sections of pure annealed Mo single crystals. No a priori sources for dislocation multiplication are introduced, and yet multiplication takes place through a sequence involving aggregation of grown-in superjogs, bowing of screw dislocation segments and fast lateral motion of edge segments, producing a large number of elongated loops and a characteristic cross-grid pattern of screw dislocations.     

Genetic and environmental influences on antisocial behavior: a meta-analysis of twin and adoption studies

A meta-analysis of 51 twin and adoption studies was conducted to estimate the magnitude of genetic and environmental influences on antisocial behavior. The best fitting model included moderate proportions of variance due to additive genetic influences (.32), nonadditive genetic influences (.09), shared environmental influences (.16), and nonshared environmental influences (.43). The magnitude of familial influences (i.e., both genetic and shared environmental influences) was lower in parent-offspring adoption studies than in both twin studies and sibling adoption studies. Operationalization, assessment method, zygosity determination method, and age were significant moderators of the magnitude of genetic and environmental influences on antisocial behavior, but there were no significant differences in the magnitude of genetic and environmental influences for males and females.
