Participation in school environment of children and youth with disabilities: a person-oriented approach

This study investigated patterns of interrelated positive subject and environmental factors related to participation in school activities of pupils with different kinds of disabilities. Questionnaires concerning participation were collected from 472 pupils with disabilities and their teachers, parents and special education consultants. A person-oriented approach with the aim to identify patterns of variables related to a high degree of participation of pupils with disabilities was used. Cluster-groups were formed based on scores for individual subjects on factors identified as important for participation. Groups with a high degree of participation were characterized by high scores in autonomy and perceived interaction with peers and teachers and an internal locus of control. Type and degree of disability did not predict cluster group membership. A conclusion is that the outcome participation is better predicted by patterns of interrelated positive subject and environmental factors than by type of disability or any other single factor.     

The Role of Cognitive Deficits in the Development of Eating Disorders

Eating disorders (ED), including anorexia and bulimia nervosa, are chronic illnesses with periods of symptom exacerbation and remission. Because symptoms are usually present from 6 to 24 months before a diagnosis is made, aetiological agents are believed to be active well before symptoms appear. It is proposed that neuropsychological deficits in various cognitive domains preexist and underlie the aetiology of ED. This paper provides a comprehensive review of the literature relevant to neuropsychological deficits in ED patients and explores the relationship between cognitive deficits, psychosocial development, and the development of ED. Although the role of neuropsychological deficits in the evolution of ED requires further research, the proposed association has significant implications for clinical practice.     

Experienced closeness and distance among family members

This study looks at experienced emotional closeness among family members using a projective measure, the Family Paper Sculpture. Results support the hypothesis that, in a non-clinical population, experiences of extreme closeness and extreme distance may be different manifestations of the same underlying process. Some support is found for the hypothesis that families in which relationships are experienced as very close or very distant at one point in time may experience those same relationships as extreme in the opposite direction at another point in time. Global coding of taped family interactions supports the hypothesis that extremes of experienced closeness are associated with more conflict, less ability to resolve differences, and less warmth and support among family members. It is suggested that the experience of being very close, varying through time with the experience of being very distant, may be associated with disappointed attempts to achieve closeness with autonomy.worked on this research while a graduate student in psychology at the University of Houston-Clear Lake.David C. Bell, PhD, completed work on this report while at Texas A & M University. He is presently working on a book about connection and dependency.The studies reported here were supported by grants from the National Institute for Mental Health and the Hogg Foundation for Mental Health.

Task familiarity and task efficacy: a study of sports coaches

The purpose of the study was to establish a profile of coaching efficacy with Hong Kong community coaches who differ in knowledge and hours spent in coaching. Coaching efficacy can be described in four dimensions, namely, Motivation, Strategy, Technique, and Character Building. It was hypothesized that coaches who had spent more time coaching and were more knowledgeable about the sport and coaching would score higher on those four dimensions of a Coaching Efficacy Scale. The scale was administered to 252 coaches working with beginning and district-level athletes in a variety of sports. Analysis suggested that their self-reported efficacy on Strategy was least strong. This means that the coaches were not confident in analyzing the strengths and weaknesses of opposing teams, making decisions on the type of game strategy to employ, and maximizing athletes' strength in competitions. Coaches with less coaching experience were also less confident about motivating athletes. This information on coaching efficacy may be useful in deciding content for a program of education for coaching.     

Between facets and domains: 10 aspects of the Big Five

Factor analyses of 75 facet scales from 2 major Big Five inventories, in the Eugene-Springfield community sample (N=481), produced a 2-factor solution for the 15 facets in each domain. These findings indicate the existence of 2 distinct (but correlated) aspects within each of the Big Five, representing an intermediate level of personality structure between facets and domains. The authors characterized these factors in detail at the item level by correlating factor scores with the International Personality Item Pool (L. R. Goldberg, 1999). These correlations allowed the construction of a 100-item measure of the 10 factors (the Big Five Aspect Scales [BFAS]), which was validated in a 2nd sample (N=480). Finally, the authors examined the correlations of the 10 factors with scores derived from 10 genetic factors that a previous study identified underlying the shared variance among the Revised NEO Personality Inventory facets (K. L. Jang et al., 2002). The correspondence was strong enough to suggest that the 10 aspects of the Big Five may have distinct biological substrates.     

Reexamining the factor structure of the 20-item Toronto alexithymia scale: commentary on Gignac, Palmer, and Stough

Gignac, Palmer, and Stough (2007/this issue) test a number of different latent factor models for the TAS-20 using a community sample of 355 participants and conclude that this scale is best represented by a "nested factors model," with five substantive factors and a method factor. Gignac et al. also report that the correlated three-factor model and a comparable higher order model supported by most studies produced poor levels of incremental close fit. In this article, we challenge Gignac et al.'s unheralded and largely unsupported use of nested model fitting and the uncritical acceptance of exceptionally high cutoff levels to assess goodness of fit (GOF). Using more traditional and empirically supported model testing procedures and a more flexible approach to the interpretation of multiple tests of GOF, we interpret Gignac et al.'s results as actually supportive of the traditional three-factor model and one that has been recovered in 17 of the 24 factor analytic studies of the TAS-20.     

Openness to Experience,Intellect, and Cognitive Ability

An instrument designed to separate 2 midlevel traits within each of the Big Five (the Big Five Aspect Scales [BFAS]) was used to clarify the relation of personality to cognitive ability. The BFAS measures Openness to Experience and Intellect as separate (although related) traits, and refers to the broader Big Five trait as Openness/Intellect. In 2 samples (N = 125 and 189), Intellect was independently associated with general intelligence (g) and with verbal and nonverbal intelligence about equally. Openness was independently associated only with verbal intelligence. Implications of these findings are discussed for the empirical and conceptual relations of intelligence to personality and for the mechanisms potentially underlying both Openness/Intellect and cognitive ability.     

Exploring the tractability border in epistemic tasks

We analyse the computational complexity of comparing informational structures. Intuitively, we study the complexity of deciding queries such as the following: Is Alice’s epistemic information strictly coarser than Bob’s? Do Alice and Bob have the same knowledge about each other’s knowledge? Is it possible to manipulate Alice in a way that she will have the same beliefs as Bob? The results show that these problems lie on both sides of the border between tractability (P) and intractability (NP-hard). In particular, we investigate the impact of assuming information structures to be partition-based (rather than arbitrary relational structures) on the complexity of various problems. We focus on the tractability of concrete epistemic tasks and not on epistemic logics describing them.
