Acceptance of illness is related to better mental health among patients with chronic illness; however, this construct has not been evaluated as part of routine transplantation evaluations. The purpose of this study was to create a brief measure of acceptance of illness for patients pursuing organ transplantation and examine how acceptance is related to distress. Retrospective medical record reviews were conducted for 290 patients who completed a routine psychosocial evaluation prior to transplant listing which included the Illness Acceptance Scale (IAS). Internal consistency for the IAS was excellent (Cronbach’s alpha?=?.92). Illness acceptance was negatively correlated with depression, anxiety, and catastrophizing and was not related to health literacy or health numeracy. The IAS is a reliable and valid measure for patients who are pursuing thoracic transplant or left ventricular assist device. Clinicians may want to screen transplant candidates for illness acceptance and refer those with lower levels to psychological interventions.

The aim of this study was to examine the impact of end-of-life (EoL) circumstances on grief and internalizing symptoms among bereaved siblings. Bereaved families (N?=?88) were recruited from three sites 3–12 months (M?=?11.57, SD?=?3.48) after their child’s death from cancer. One sibling per family aged 8–17 years (M?=?12.41, SD?=?2.64) was randomly selected to participate. Families completed measures of siblings’ grief and internalizing symptoms, as well as a structured interview about circumstances surrounding the death. Mother and sibling reports of EoL circumstances were generally concordant, except there was a discrepancy between mothers and children about whether or not children expected their sibling’s death (t(75)?=?1.52, p?=?.018). Mother reports of sibling internalizing symptoms were above the normative mean (t(83)?=?4.44, p?≤?.001 (M?=?56.01?±?12.48), with 39% (n?=?33) in the borderline/clinical range. Sibling opportunity to say goodbye was associated with greater grief-related growth (t(79)?=?? 1.95, p?=?.05). Presence at the death and wishing they had done something differently were both associated with greater grief (t(80)?=?? 2.08, p?=?.04 and t(80)?=?? 2.24, p?=?.028, respectively) and grief-related growth (t(80)?=?? 2.01, p?=?.048 and t(80)?=?? 2.31, p?=?.024, respectively). However, findings were primarily unique to sibling report, with few mother-reported effects. The adjustment of bereaved siblings may be affected by certain modifiable circumstances surrounding the death of their brother or sister. A proportion of bereaved siblings had elevated internalizing symptoms irrespective of circumstances at EoL. Further work is needed to understand predictors of adjustment among bereaved siblings to provide better support and optimize their outcomes.

No single paradigm or debate currently orients the social scientific study of religion. Because of this, those engaged in the multidisciplinary study of religion find that a public conversation is often difficult. In this article and the Forum it introduces, we explore Martin Riesebrodt's recently published book, The Promise of Salvation: A Theory of Religion. Responding to the inadequacies of secularization paradigms, rational choice models, and postmodern criticism, Riesebrodt proposes an approach that ideal‐typically reconstructs the subjective meanings of institutionalized religious practices (liturgies). These subjective meanings center on the prevention and management of crises—social, natural, and bodily—through appeal and access to superhuman powers. This pragmatic emphasis on the superhuman defines religion as a distinct sphere of social action transhistorically and transculturally. Riesebrodt's theory creates new analytical possibilities, especially for understanding the modern resurgence of religion under conditions of secularization.  相似文献

People will often grasp an object with an uncomfortable initial grasp if this affords more comfort at the end of the movement. The authors' primary objective was to examine whether grasp planning is influenced by precision demands at the start and end of the movement. Twenty right-handed individuals performed a unimanual grasping and placing task in which the precision requirements at the start and end of the movement were either identical (low initial and final precision, high initial and final precision) or different (low initial and high final precision, high initial and low final precision). The major finding to emerge was the presence of individual differences. 50% of participants changed their initial grasps based on the precision requirements of the task, and were more likely to satisfy end-state comfort when the final precision requirements were high than when they were low. In contrast, 50% of participants generally planned their movements to satisfy end-state comfort (regardless of precision requirements). The authors hypothesized that the former group of participants was sensitive to the precision demands of the task, and participants planned their grips in accordance with these demands. In contrast, the latter group of participants reduced the cognitive costs by using previously successful grasp plans.  相似文献

The cognitive discrepancy model predicts that loneliness occurs when individuals perceive a difference between their desired and actual levels of social involvement. Using data from a sample of high school sophomore students, the present investigation was designed to go beyond previous research that has tested this model by examining the predicted nonlinear relationships between desired and actual social contact and feelings of loneliness. Analyses indicated that support for the cognitive discrepancy model of loneliness was found only for measures of close friendships. Specifically, the discrepancy between the students' ideal number and actual number of close friends was found to be related in a nonlinear fashion to feelings of satisfaction with close friendships and loneliness after control for the number of close friends. Implications of these findings for theoretical models of loneliness are discussed.  相似文献

Drawing on principles relating to the duty of easy rescue, I argue that any atheist who is less than wholly certain of the non-existence of a God or gods will in some circumstances be morally obliged to pray.  相似文献

In an eyetracking study, we examined whether readers use psychological essentialist reasoning and perspective taking online. Stories were presented in which an animal or an artifact was transformed into another animal (e.g., a donkey into a zebra) or artifact (e.g., a plate into a clock). According to psychological essentialism, the essence of the animal did not change in these stories, while the transformed artifact would be thought to have changed categories. We found evidence that readers use this kind of reasoning online: When reference was made to the transformed animal, the nontransformed term (“donkey”) was preferred, but the opposite held for the transformed artifact (“clock” was read faster than “plate”). The immediacy of the effect suggests that this kind of reasoning is employed automatically. Perspective taking was examined within the same stories by the introduction of a novel story character. This character, who was naïve about the transformation, commented on the transformed animal or artifact. If the reader were to take this character’s perspective immediately and exclusively for reference solving, then only the transformed term (“zebra” or “clock”) would be felicitous. However, the results suggested that while this character’s perspective could be taken into account, it seems difficult to completely discard one’s own perspective at the same time.  相似文献
