Factor Structure of the Illness Intrusiveness Rating Scale in Patients Diagnosed with Anxiety Disorders

The Illness Intrusiveness Rating Scale (IIRS) is a measure designed to assess the impact of illness on various domains of functioning (G. M. Devins, 1994). In anxiety disordered patients, illness intrusiveness ratings are higher than those of chronically ill medical patients, suggesting that the IIRS may have a different underlying structure in a sample of individuals with anxiety disorders. To examine this possibility, IIRS items were submitted to an exploratory and confirmatory factor analysis in 2 samples (total N = 294). These solutions were compared to solutions in chronically ill populations from a previous study. In the exploratory analysis, both a one-factor and a three-factor solution were identified, accounting for 42 and 61% of the variance, respectively. Confirmatory analyses showed adequate similarity between the three-factor structure of the IIRS from a medically ill population and the current three-factor structure, suggesting that elevated IIRS scores in anxiety disordered samples cannot be explained simply by a different structure of the instrument.     

Why The Pessimistic Induction Is A Fallacy

Putnam and Laudan separately argue that the falsity of past scientific theories gives us reason to doubt the truth of current theories. Their arguments have been highly influential, and have generated a significant literature over the past couple of decades. Most of this literature attempts to defend scientific realism by attacking the historical evidence on which the premises of the relevant argument are based. However, I argue that both Putnam's and Laudan's arguments are fallacious, and hence attacking their premises is unnecessary. The paper concludes with a discussion of the further historical evidence that would be required if the pessimistic induction is to present a serious threat to scientific realism.     

《英国美学杂志》40年

在千年纪元到来之际,《英国美学杂志》刚好推出它的第40卷,进入它的不惑之年。这就给了我们一个恰当的时机,透过刊物的视野,借几页序言的篇幅,对近半个世纪的美学及其前景做些许概括性的反思。严格说来,本刊的40周岁要到2000年秋季号才满,因为1960年秋天我们的第1期才面世。但是这些周而复始的数字有一种诱惑,鼓动我们将第40卷的首期与新千年的开始重合在一起,其真实理由不过是希望引起特别的注意。     

Foetal testosterone and vocabulary size in 18- and 24-month-old infants

Amniotic fluid, obtained from 87 pregnant women for routine amniocentesis, was analysed for foetal testosterone (FT) level. Their infants (40 girls and 47 boys) were followed up 18 and 24 months after birth and their vocabulary size was assessed. Girls were found to have a significantly larger vocabulary than boys at both ages. This replicates previous findings of a female advantage in language ability, but reveals this sex difference at the earliest point of development. Additionally, FT was an inverse predictor of vocabulary size when data from both sexes was examined together, but not within sex. The lack of a significant correlation between FT and vocabulary within each sex may reflect the relatively small sample size. However, the significant correlation between FT and vocabulary when the sexes were combined suggests FT might be involved in shaping the neural mechanisms underlying communicative development.     

Emotional stability as a major dimension of happiness

Happiness is associated with both extraversion and neuroticism, and extraversion is generally considered the more important. A recent study of happy introverts has shown that extraversion is not always an essential correlate of happiness, and an extensive meta-analysis has found that neuroticism is a greater predictor of both happiness and life satisfaction. It is suggested that the reason for the importance of neuroticism having been overlooked in the past, is the difficulty of handling the idea that (positive) happiness is related to the absence of a (negative) construct. This difficulty could be resolved by the reversal of neuroticism into an alternative and positive concept of “emotional stability”. Happiness could then be regarded as being associated with two positive qualities. With this change of emphasis, a short empirical study has been made of the relationships between happiness as measured by the Oxford Happiness Inventory (OHI) and extraversion and emotional stability. In bivariate and partial correlation, emotional stability was more strongly associated with happiness than extraversion, and accounted for more of the total variability in multiple regression. Emotional stability was also the greater correlate for a majority of the 29 items of the OHI, and the sole significant predictor of the happiness of younger people.     

The removal of pluto from the class of planets and homosexuality from the class of psychiatric disorders: a comparison

We compare astronomers' removal of Pluto from the listing of planets and psychiatrists' removal of homosexuality from the listing of mental disorders. Although the political maneuverings that emerged in both controversies are less than scientifically ideal, we argue that competition for "scientific authority" among competing groups is a normal part of scientific progress. In both cases, a complicated relationship between abstract constructs and evidence made the classification problem thorny.     

Testosterone, cortisol, and serotonin as key regulators of social aggression: A review and theoretical perspective

In human and non-human animals the steroid hormones cortisol and testosterone are involved in social aggression and recent studies suggest that these steroids might jointly regulate this behavior. It has been hypothesized that the imbalance between cortisol and testosterone levels is predictive for aggressive psychopathology, with high testosterone to cortisol ratio predisposing to a socially aggressive behavioral style. In this review, we focus on the effects of cortisol and testosterone on human social aggression, as well as on how they might modulate the aggression circuitry of the human brain. Recently, serotonin is hypothesized to differentiate between impulsive and instrumental aggression, and we will briefly review evidence on this hypothesis. The aim of this article is to provide a theoretical framework for the role of steroids and serotonin in impulsive social aggression in humans.     

The clinical pain acceptance Q-sort: a tool for assessment and facilitation of pain acceptance

The topic of pain acceptance can be clinically difficult to raise in a respectful way. This article introduces a method of managing the topic of pain acceptance in daily clinical practice: The clinical pain acceptance Q-sort. The Q-sort procedure comprises 13 small cards with printed statements concerning pain acceptance on the one side, score numbers on the other side. The procedure involves the patient handling and prioritizing the statements in a personally meaningful order. Both quantitative and qualitative use of the tool is possible. The method has a three-fold outcome: (1) topics of pain acceptance are presented in a multi-faceted way for the chronic pain patient, (2) an approximate assessment of the level of pain acceptance issues is offered to the clinician, and (3) good opportunities for a therapeutic discussion on pain acceptance are made available. The clinical pain acceptance Q-sort procedure may positively contribute to daily clinical work with pain acceptance in a straightforward way. The method provides options for assessment of pain acceptance, for better understanding of the patient, and for clinical training in psychological pain management.
