Parents of individuals with autism spectrum disorders (ASD) often experience stressors associated with caring for their child. These stressors can cause considerable distress for families, which at times can develop into full blown crisis, and it is important that professionals be able to quickly identify when families are approaching or are in crisis to respond appropriately. The current study presents an initial attempt at measuring the subjective experience of crisis in 164 caregivers of people with ASD through a single item instrument, the Brief Family Distress Scale. The BFDS was negatively correlated with helpful coping mechanisms (family hardiness, and parent empowerment), and positive adjustment (caregiver quality of life and positive parenting experiences), and positively correlated with known stressors (severity of aggressive behavior, negative life events) and problematic coping and outcomes (caregiver burden, worry, mental health problems). As expected, caregivers at Marked levels of distress (approaching or in crisis) were significantly different from caregivers at lower levels of distress in nearly all of the dependent variables. Having a quick way of measuring where families are in terms of distress and crisis can be helpful for researchers and clinicians alike.  相似文献

This study aims to reveal correlates of depressive and anxiety symptoms among the Turkish caregivers of leukemic children (n?=?100). The effects of demographic variables, satisfaction of the basic needs, performance on daily activities, and coping strategies on outcome variables were investigated by hierarchical regression. Accordingly, older age, lower reported income, higher number of other children to be looked after, lower levels of satisfaction of basic needs, and more use of emotion focused coping were associated with higher levels of both depressive and anxiety symptoms. Moreover, caregivers with lower education reported more depressive symptoms, and higher performance on daily activities predicted more anxiety symptoms.  相似文献

The purpose of this study was to investigate whether patients with multiple sclerosis (MS) and their partners show adversarial growth and to examine which psychological and disability variables contribute to this in patients and their partners. The study also investigated the relationship between growth and distress. Seventy-two patients with MS and their partners provided demographic information and completed measures of posttraumatic growth, illness perceptions, depression, cognitive function and disability. Both patients and partners showed adversarial growth, with patients reporting significantly higher growth than partners. The only significant predictor for patient growth was partner growth, and vice versa. Dissimilarity in illness representations between patients and their partners on the consequences of MS dimension, patient mood and patient growth accounted for significant variance in partner growth. The findings support the idea of a ‘communal search for meaning’ where patients and their partners experience the trauma of having a chronic illness and subsequently find positive aspects together.  相似文献

The main formal structures of generalized quantum theory are summarized. Recent progress has sharpened some of the concepts, in particular the notion of an observable, the action of an observable on states (putting more emphasis on the role of proposition observables), and the concept of generalized entanglement. Furthermore, the active role of the observer in the structure of observables and the partitioning of systems is emphasized.  相似文献

This paper presents data concerning culturally prescribed gender traits and their influence on bullying/victimization problems and aggressive tendencies from a wide sample of 1,654 Spanish adolescents. The aims of this study were to clarify the effect of masculine traits on male and female secondary students’ aggression, and also to explore the role of feminine traits in either the inhibition of aggression or the use of more covert forms. Results show that masculine stereotypical traits are related more strongly with bully perpetration, proneness to aggression and experience of anger and hostility in both sexes. In contrast, traditional feminine traits are negatively related with bullying perpetration and proneness to aggression. However, feminine traits are linked to male students’ victimization. Results are discussed in the light of previous findings and are taken into consideration in the design of intervention practices in secondary schools.  相似文献

This paper argues that Derrida’s aporetic conclusions regarding moral and political concepts, from hospitality to democracy, can only be understood and accepted if the notion of différance and similar infrastructures are taken into account. This is because it is the infrastructures that expose and commit moral and political practices to a double and conflictual (thus aporetic) future: the conditional future that projects horizonal limits and conditions upon the relation to others, and the unconditional future without horizons of anticipation. The argument thus turns against two kinds of interpretation: The first accepts normative unconditionality in ethics but misses its support by the infrastructures. The second rejects unconditionality as a normative commitment precisely because the infrastructural support for unconditionality seems to rule out that it is normatively required. In conclusion, the article thus reconsiders the relation between a quasi-transcendental argument and its normative implications, suggesting that Derrida avoids the naturalistic fallacy.  相似文献

The major problem with the current emotional well-being scales is that they lack intentionality (being about something), which makes them incongruent with the definition of subjective well-being. A new emotional well-being scale with new affect adjectives has been developed by addressing intentionality. It focuses on individuals’ affective evaluations of their life and has showed good psychometric quality. In the first and second studies, the factor structure of the scale, the Emotional Well-Being Scale, was determined by exploratory and confirmatory factor analyses. Study 3 showed that the scores on the scale were stable in time. The fourth and fifth studies indicated that this new construct did not overlap with personality dimensions of extraversion and neuroticism, with impressive predictive and incremental validity estimates.  相似文献

Although analogical reasoning has long been a popular method of reasoning in bioethics, current literature does not sufficiently grasp its variety. We assert that the main shortcoming is the fact that an analogy’s value is often judged on the extent of similarity between the source situation and the target situation, while in (bio)ethics, analogies are often used because of certain dissimilarities rather than in spite of them. We make a clear distinction between dissimilarities that aim to reinforce a similar approach in the source situation and the target situation and dissimilarities that aim to undermine or denounce a similar approach. The former kind of dissimilarity offers the analogy more normative force than if there were no dissimilarities present; this is often overlooked by authors who regard all relevant dissimilarities as detrimental to the analogy’s strength. Another observation is that an evaluation of the normative force of an analogy cannot be made independently of moral principles or theories. Without these, one cannot select which elements in an analogy are morally relevant nor determine how they should be interpreted.  相似文献
