Preliminary validation of a Spanish language version of the Adoption Communication Scale in adopted adolescents / Validación preliminar de una versión en español de la escala Adoption Communication Scale para adolescentes adoptados

Abstract

The Adoption Communication Scale (ACS) is a 28-item child-report instrument used to assess adoptees’ perception of communication openness in the family. The aim was to develop a Spanish language version of the scale (ACS-S) and to assess the instrument’s psychometric properties in a sample of 55 adopted adolescents. The ACS-S was found to have high internal consistency (α = .93) and moderately high test-retest stability (.68). An exploratory factorial analysis yielded two factors, the first loaded on satisfaction with emotional communication items and the second encompassing satisfaction with the completeness of the information offered by the parents. These factors are coherent with the theory underlying the scale. The total ACS-S score was significantly positively correlated with adolescent Global Satisfaction with Openness as measured by a Visual Analogue Scale. The ACS-S scale appears to be a valid tool in assessing communication openness in Spanish adopted adolescents.     

Implementing Housing First Across Sites and Over Time: Later Fidelity and Implementation Evaluation of a Pan-Canadian Multi-site Housing First Program for Homeless People with Mental Illness

This article examines later fidelity and implementation of a five‐site pan‐Canadian Housing First research demonstration project. The average fidelity score across five Housing First domains and 10 programs was high in the first year of operation (3.47/4) and higher in the third year of operation (3.62/4). Qualitative interviews (36 key informant interviews and 17 focus groups) revealed that staff expertise, partnerships with other services, and leadership facilitated implementation, while staff turnover, rehousing participants, participant isolation, and limited vocational/educational supports impeded implementation. The findings shed light on important implementation “drivers” at the staff, program, and community levels.     

Einstellung defused: Interactivity and mental set

Mental set is observed when a familiar problem-solving strategy is applied to new problems that can be solved in simpler, more efficient ways. It is most famously illustrated in the water jar problems (Luchins, 1942 ). In these volume measurement problems, participants learn a rule to obtain an exact volume of liquid involving a complex combination of liquid transfer. Participants persevere in using this rule for new problems that can be solved with a much simpler rule. In two experiments presented here, participants completed the water jar task either in interactive conditions with actual water jars at a sink or in noninteractive conditions, with the problems presented on paper, as in the original Luchins procedure. Interactivity significantly reduced the degree of perseverance. In addition, participants' visuospatial skills significantly predicted the rate of perseverance (and the latencies to solution) in interactive but not in noninteractive conditions. These results underscore the importance of designing problem-solving experiments that engineer distributed cognitive systems in which participants coordinate internal and external resources in thinking.     

A single exposure to severe stressors causes long-term desensitisation of the physiological response to the homotypic stressor

Although some laboratories have reported that a single session of stress is able to induce a long-lasting sensitisation of the hypothalamic-pituitary-adrenal (HPA) response to further exposures to stress, we have found that a single exposure to severe emotional (immobilisation, restraint or shock) or systemic (endotoxin) stressors reduces the responsiveness of the HPA to the same, but not to a novel (heterotypic), stressor, in which case a slight sensitisation was observed. Long-term desensitisation has been found to reduce not only secretion of peripheral HPA hormones (ACTH and corticosterone), but also to reduce responses of central components of the HPA axis (c-fos and CRF gene expression at the level of the paraventricular nucleus of the hypothalamus, PVN). In addition, desensitisation also applies to the impact of the stressor on food intake and, probably, to stress-induced hyperglycaemia. The development of long-term desensitisation of the HPA axis does not appear to be a universal consequence of exposure to severe stressors as it was not observed in response to insulin-induced hypoglycaemia. Whether or not the development of long-term effects of stress depend on the specific pathways activated by particular stressors remains to be tested. The observed desensitisation of the HPA axis in response to the homotypic stressor shows two special features which makes it difficult to be interpreted in terms of an habituation-like process: (a) the effect increased with time (days to weeks) elapsed between the first and second exposure to the stressor, suggesting a progressive maturational process; and (b) the stronger the stressor the greater the long-term desensitisation. Therefore, it is possible that desensitisation of the HPA axis is the sum of two different phenomena: long-term effects and habituation-like processes. The contribution of the former may be more relevant with severe stressors and longer inter-stress intervals, and that of the latter with mild stressors and repeated exposures. Long-term stress-induced changes may not take place at the level of the PVN itself, but in brain nuclei showing synaptic plasticity and putatively involved in the control of the HPA axis and other physiological responses. As for the precise areas involved, these remain to be characterized.     

Asymptotic judgment of cause in a relative validity paradigm

We report three experiments in which we tested asymptotic and dynamic predictions of the Rescorla-Wagner (R-W) model and the asymptotic predictions of Cheng's probabilistic contrast model (PCM) concerning judgments of causality when there are two possible causal candidates. We used a paradigm in which the presence of a causal candidate that is highly correlated with an effect influences judgments of a second, moderately correlated or uncorrelated cause. In Experiment 1, which involved a moderate outcome density, judgments of a moderately positive cause were attenuated when it was paired with either a perfect positive or perfect negative cause. This attenuation was robust over a large set of trials but was greater when the strong predictor was positive. In Experiment 2, in which there was a low overall density of outcomes, judgments of a moderately correlated positive cause were elevated when this cause was paired with a perfect negative causal candidate. This elevation was also quite robust over a large set of trials. In Experiment 3, estimates of the strength of a causal candidate that was uncorrelated with the outcome were reduced when it was paired with a perfect cause. The predictions of three theoretical models of causal judgments are considered. Both the R-W model and Cheng's PCM accounted for some but not all aspects of the data. Pearce's model of stimulus generalization accounts for a greater proportion of the data.     

Psychological consequences of rheumatic diseases in children and adolescents: A first exploratory study

The objective of our study was to make a first exploratory study about the psychological status of children and adolescents with rheumatic diseases exploring, also, the significant differences between girls and boys. A total of 123 children (81 girls and 42 boys) with rheumatic diseases, between the ages of 1 and 19 years old were assessed using different measures for evaluating behavioral and emotional problems. The results showed a picture of a mild or moderate degree of psychological problems in the different measures of anxiety, depression, general distress and behavioral problems. Girls, compared to boys, scored higher in most of the measures used, showing more internalizing than externalizing kinds of symptoms. The results suggest the importance of making a more detailed study of these children, comparing them with matched controls and making prospective, longitudinal studies in order to detect psychological problems, and to explore the influence of predictive variables.     

Death and the Evolution of Language

My hypothesis is that the cognitive challenge posed by death might have had a co-evolutionary role in the development of linguistic faculties. First, I claim that mirror neurons, which enable us to understand others’ actions and emotions, not only activate when we directly observe someone, but can also be triggered by language: words make us feel bodily sensations. Second, I argue that the death of another individual cannot be understood by virtue of the mirror neuron mechanism, since the dead provide no neural pattern for mirroring: this cognitive task requires symbolic thought, which in turn involves emotions. Third, I describe the symbolic leap of the human species as a cognitive detachment from the here and now, allowing displaced reference: through symbols the human mind can refer to what is absent, possible, or even impossible (like the presence of a dead person). Such a detachment has had a huge adaptive impact: adopting a coevolutionary standpoint can help explain why language is as effective as environmental inputs in order to stimulate our bodily experience. In the end I suggest a further coevolutionary “reversal”: if language is necessary to understand the death of the other, it might also be true that the peculiar cognitive problem posed by the death of the other (the corpse is present, but the other is absent) has contributed to the crucial transition from an indexical sign system to the symbolic level, i.e., the “cognitive detachment”. Death and language, as Heidegger claimed, have an essential relation for humans, both from an evolutionary and a phenomenological perspective: they have shaped the symbolic consciousness that make us conceive of them.     

Le « test par CDD » comme frein au fonctionnement des entreprises

In France, in order to evaluate job applicants, some employers use short term contract before recruiting on a long term contract. The present study aims to compare companies having this practice and others. More precisely, we will appreciate the level of recruitment difficulties and the degree of fundamental error of attribution according companies. Results indicate that companies having “test by CDD” have more recruitment difficulties and more fundamental error of attribution to explain these failures.
