Conditional covariance structure of generalized compensatory multidimensional items

Some nonparametric dimensionality assessment procedures, such as DIMTEST and DETECT, use nonparametric estimates of item pair conditional covariances given an appropriately chosen subtest score as their basic building blocks. Such conditional covariances given some subtest score can be regarded as an approximation to the conditional covariances given an appropriately chosen unidimensional latent composite, where the composite is oriented in the multidimensional test space direction in which the subtest score measures best. In this paper, the structure and properties of such item pair conditional covariances given a unidimensional latent composite are thoroughly investigated, assuming a semiparametric IRT modeling framework called a generalized compensatory model. It is shown that such conditional covariances are highly informative about the multidimensionality structure of a test. The theory developed here is very useful in establishing properties of dimensionality assessment procedures, current and yet to be developed, that are based upon estimating such conditional covariances.In particular, the new theory is used to justify the DIMTEST procedure. Because of the importance of conditional covariance estimation, a new bias reducing approach is presented. A byproduct of likely independent importance beyond the study of conditional covariances is a rigorous score information based definition of an item's and a score's direction of best measurement in the multidimensional test space.This paper is based on a chapter of the first author's doctoral dissertation, written at the University of Illinois and supervised by the second author.

感染后与非感染后肠易激综合征的多维特点

探讨感染后(PI)与非感染后肠易激综合征(NPI-IBS)的临床,精神心理,组织学特点。取IBS患者和正常人进行问卷调查,了解其多维特点。分别检测肥大细胞的数目。结果显示:(1)PI-IBS与NPI-IBS患者临床、心理特征不同;(2)IBS两组患者肥大细胞的数目无差异,与对照组比较差异明显。因此认为PI-IBS和NPI-IBS有特征差异,对临床治疗有一定指导意义。     

Self-reported health and cortisol awakening response in parents of people with asperger syndrome: The role of trait anger and anxiety,coping and burden

Caring for offspring with autism spectrum disorders entails high levels of stress for a long period of time and is associated with several types of health complaints. Few studies have focused on specific effects of particular disorders in the spectrum. This study was carried out with the aim of evaluating the global health of parents of people with Asperger syndrome (N?=?53) compared to those of typically developing children (N?=?54) through self-reported measures (medication consumption and somatic symptoms) and biological markers (cortisol awakening response [CAR]). Additionally, we analysed various psychological variables as potential predictors of caregiver health. We found that caregivers take more medication and have worse self-reported health than controls, but there were no significant differences in CAR between the groups. However, after controlling for negative affect, differences between groups in CAR reached significance. With regards to predictor variables, anxiety trait, cognitive-coping style, burden and anger temperament were significantly associated with caregiver’s self-reported health. These findings underline the need to develop interventions that foster improvements in the health of caregivers, reduce their burden and enhance their quality of life.

A pilot study examining the effects of priming headache illness schema on attentional engagement towards pain relief medication,in those with high and low medication treatment beliefs

Few studies have assessed the underlying theoretical components of the Common Sense Model. Past studies have found, through implicit priming, that coping strategies are embedded within illness schema. Our aim was to evaluate the effect priming ‘headache’ illness schema upon attentional engagement to pain relief medication and to examine the interaction with illness treatment beliefs. Attentional engagement to the pain relief medication (‘Paracetamol’) was assessed using a 2 (primed vs. control) × 2 (strong belief in medication efficacy vs. weak belief in medication efficacy) design. During a grammatical decision task (identifying verbs/non-verbs), participants were randomised to receive a headache prime or a control. Response latency to the target word, ‘Paracetamol’ was the dependent variable. ‘Paracetamol’ treatment beliefs were determined using the brief illness perception questionnaire. Sixty-three participants completed the experiment. There was a significant interaction between illness-primed vs. control and high vs. low treatment efficacy of Paracetamol (p < .001), suggesting an attentional disengagement effect to the coping strategy in illness-primed participants whom held stronger treatment beliefs regarding the efficacy of Paracetamol. In summary, implicit illness schema activation may simultaneously activate embedded coping strategies, which appears to be moderated by specific illness beliefs.     

Psychosocial correlates of immune status and disease progression in HIV-1 infected homosexual men: Review of preliminary findings,and commentary

Abstract

Behavioral factors may have an effect on the course of infection in HIV-1 infected individuals. These effects can be mediated by the immune system of the host, which, based on psychoneuroimmunologic findings, can be affected by some psychosocial factors. We present a short review of some putative psychoneuroimmunologic pathways and their possible implications for HIV-1 infected individuals. We next summarize the findings of recent psychoimmunological work with HIV-1 seropositives and discuss the methodological problems in studying the psychoneuroimmunologic aspects of HIV-1 infection. Psychoneuroimmunologic research in HIV-1 seropositives is a rapidly developing field, yielding contradictory findings so far, but which in the long run could provide important knowledge for psychoimmunologic interventions, targeted at improving or preserving immune status and retarding disease progression, as well as optimizing psychosocial functioning.     

液体潴留量与重症急性胰腺炎早期并发ARDS相关性临床分析

探讨48h液体潴留量〉4000ml与重症急性胰腺炎（SAP）早期并发急性呼吸窘迫综合征（ARDS）的临床相关性,为进一步指导11盏床SAP患者早期液体复苏治疗并预防急性肺损伤提供科学依据。回顾性分析我院2012年1月至2014年1月收治的43例SAP患者临床资料,并进行统计学处理。分析结果表明48h液体潴留量〉4000m1与sAP早期并发ARDS呈现出明显的正相关,48h液体潴留量〉4000ml的sAP患者早期并发ARDs的危险性是48h液体潴留量〈4000ml的SAP患者的14．4倍,48h液体潴留量〉4000ml是重症急性胰腺炎早期并发ARDS的高危险因素。对于SAP患者在早期临床治疗过程中应密切注意液体潴留量,通过合理补液可降低sAP并发ARDS的发生率和病死率。
