Resilience,religiosity and treatment adherence in hemodialysis patients: a prospective study

Resilience and religiosity have received attention as an important process in the experience and management of chronic comorbidities; however, there is no study evaluating resilience in hemodialysis patients and its association with other psychological dimensions or with treatment adherence. This observational prospective study assessed resilience (25 item Wagnild and Young Resilience Scale), religiosity under three dimensions (organizational, non-organizational and intrinsic) using DUREL scale, depressive symptoms (Patient Health Questionnaire-9) and health-related quality of life (Short Form-36 questionnaire). The main outcomes were medication adherence using the Morisky Medication Adherence Scale-8 (MMAR-8) and the missing/shortened dialysis sessions in the following six months. Of 208 patients approached, 202 (97.1%) agreed to participate. One hundred twenty-three patients (60.9%) were males and mean age was 52.8 ± 14.8 years-old. The median time on hemodialysis was 36 months (IQR, 12, 84). 82 (40.6%) patients obtained a MMAS-8 score <6 and were considered as having ‘poor adherence’. Overall, the mean score of medication adherence was low (5.7 ± 2.1). About adherence to hemodialysis sessions, patients missed a total of 234 (1.6%) hemodialysis sessions. Forty-eight patients (23.7%) missed an average of at least three sessions in six months. Regarding adherence to medication, there was no association in the uni- or multivariate analysis between religiosity dimensions and MMAS-8 score. After adjustment, resilience was positively associated with MMAS-8 score (standardized β coefficient .239, p = .016). Organized and intrinsic religiosity were associated with adherence to dialysis sessions (standardized β coefficient .258, p = .004 and .231, p = .026, respectively). Interestingly, opposite to medication adherence, more resilient patients were associated with less adherence to hemodialysis sessions (standardized β coefficient ?.296, p = .001). Religiosity was associated with dialysis adherence but not with medication adherence. Resilience was associated with higher medication adherence but lower adherence to dialysis sessions.     

The glass is not yet half empty: agitation but not <Emphasis Type="Italic">Varroa</Emphasis> treatment causes cognitive bias in honey bees

Honey bees (Apis mellifera) are prone to judge an ambiguous stimulus negatively if they had been agitated through shaking which simulates a predator attack. Such a cognitive bias has been suggested to reflect an internal emotional state analogous to humans who judge more pessimistically when they do not feel well. In order to test cognitive bias experimentally, an animal is conditioned to respond to two different stimuli, where one is punished while the other is rewarded. Subsequently a third, ambiguous stimulus is presented and it is measured whether the subject responds as if it expects a reward or a punishment. Generally, it is assumed that negative experiences lower future expectations, rendering the animals more pessimistic. Here we tested whether a most likely negatively experienced formic acid treatment against the parasitic mite Varroa destructor also affects future expectations of honey bees. We applied an olfactory learning paradigm (i.e., conditioned proboscis extension response) using two odorants and blends of these odorants as the ambiguous stimuli. Unlike agitating honey bees, exposure to formic acid did not significantly change the response to the ambiguous stimuli in comparison with untreated bees. Overall evidence suggests that the commonest treatment against one of the most harmful bee pests has no detrimental effects on cognitive bias in honey bees.     

Is Stephen Hawking Building Walls? A Cosmic Dilemma

Stephen Hawking leaves us with the ancient hospitality dilemma: do we welcome ETIs as immigrants or build a wall to keep them away?     

语言,语义,语言表征,心理理论--从语言获得建构理论谈心理理论和语言能力的关系

语言获得建构论认为儿童利用社会和一般的认知技能进行范畴化。通过主动的用法建构获得语言符号系统。通过大量研究分析推断：儿童心理理论的发展是儿童社会认知概念系统发展和语言表征发展的结果。通过概念系统发展和语言表征以及语言功能性发展的分析,有助于理解语言能力和心理理论的关系。     

Müler-Lyer错觉作用机制的眼动研究

使用美国应用科学实验室生产的504型眼动仪,以错觉量和眼动特征为指标,考察了M櫣ller-Lyer(ML)错觉的产生及其作用过程。结果表明:(1)在ML错觉中,较长箭杆促进长度的准确判断,较长箭翼干扰长度的准确判断。减弱ML图形的总长度线索有助于降低错觉量;(3)箭杆与箭翼的交互作用对注视时间产生显著影响;(3)被试通过整合两条矛盾的线索进行长度判断,实验结果支持矛盾线索理论。     

Inventory of Overburden in Alzheimer's Patient Family Caregivers with no Specialized Training

Background/Objective: Alzheimer-type dementia is one of the most frequent causes of dependence in an aging population, which combines with a considerable demand for care. Furthermore, when the caregiver is a family member or person without specialized training, such care impacts on that person's health. The Inventory of Overburden in Alzheimer's Patient Family Caregivers with no Specialized Training (IPSO-CA24) was designed to find out the needs of these caregivers and evaluate the caregiver's burden or distress. Method: The psychometric properties of the questionnaire were analyzed (in a reliability analysis, exploratory factor analysis and confirmatory analysis) based on the responses of 255 caregivers. Results: The factor analyses showed a six-factor structure (Reaction to diagnosis, Physical health, Psychological symptomatology (caretaker), Behavioral symptomatology (patient), Knowledge of the illness, and Level of dependence) explaining 66.52% of the total variance with a reliability of .75 to .93. Support was also found for its convergent validity. Conclusions: The IPSO-CA24 responds to the need for an instrument enabling multidimensional evaluation of the burden on the family caregiver without specialized training.     

消极情绪抑制了老年人的口语产生过程

采用面孔图片启动不同的情绪,在青年人和老年人两组被试中考察积极、消极和中性情绪,以及不同情绪和年龄之间的交互作用对口语产生年老化的影响。要求青年组和老年组被试在不同的情绪启动条件下对图片进行命名。结果显示,与积极和中性情绪相比,消极情绪显著地延长了青年人和老年人口语产生的潜伏期;与青年人相比,消极情绪对老年人的影响更大。结果表明,随着年龄的增长,消极情绪对口语产生的抑制作用更强,这提示老年人应该在生活中尽量保持愉悦心情。     

Health-Related Quality of Life and Adaptive Behaviors of Adolescents with Sickle Cell Disease: Stress Processing Moderators

The objective of this study was to examine resilience among adolescents with sickle cell disease (SCD), focusing on the interaction of health-related quality of life with stress processing to explain adaptive behavior. Forty-four adolescents with SCD completed paper-and-pencil measures of health-related quality of life, appraisals (hope), pain coping strategies (e.g. adherence), and adaptive behavior. Self-reported health-related quality of life was significantly associated with adaptive behavior, as was adherence. Findings for moderation were mixed. Pain coping strategies moderated the association of health-related quality of life with adaptive behavior such that at lower levels of Coping Strategies Questionnaire (CSQ) Adherence, better quality of life was associated with higher adaptive behavior. Similarly, at higher levels of hope, better quality of life was associated with higher adaptive behavior, and poorer quality of life was associated with lower adaptive behavior. Adolescents with SCD showed resilience, particularly in terms of personal adjustment, that may be explained by their appraisals and stress processing strategies. Interventions to support an optimistic or hopeful outlook and improve adherence to recommendations for medical management of sickle cell pain may result in improved resilience/adaptive behavior.     

A confirmatory factor analysis of the "Autoconcepto Forma 5" questionnaire in young adults from Spain and Chile

The aim of this work is to examine the pentafactorial validity of the AF5 Self-Concept Questionnaire in Spanish and Chilean young adults. From the responses of a total of 4,383 young adults aged 17 to 22 years (1,918 Spanish, 44%, and 2,465 Chilean, 56%) it was analyzed the reliability of the instrument, the compared validity of the 5 oblique factor model proposed by the authors versus the unifactorial and the orthogonal alternative models, and was studied the invariance of one Chilean sample. The results of confirmatory factor analyses supported the authors' pentafactorial model. The multi-group factorial invariance showed that Chilean sample of the AF5 does not change neither the Spanish factor weights, nor the variances and covariances of the factors, or the error variances of items. Finally, the internal consistency of the five scales was good in the samples of both countries.
