OBJECTIVE: A major problem in the delivery of mental health services is the lack of availability of empirically supported treatment, particularly in rural areas. To date no studies have evaluated the administration of an empirically supported manual-based psychotherapy for a psychiatric condition via telemedicine. The aim of this study was to compare the relative efficacy and acceptability of a manual-based cognitive-behavioral therapy (CBT) for bulimia nervosa (BN) delivered in person to a comparable therapy delivered via telemedicine. METHOD: One hundred twenty-eight adults meeting DSM-IV criteria for BN or eating disorder-not otherwise specified with binge eating or purging at least once per week were recruited through referrals from clinicians and media advertisements in the targeted geographical areas. Participants were randomly assigned to receive 20 sessions of manual-based, CBT for BN over 16 weeks delivered either face-to-face (FTF-CBT) or via telemedicine (TV-CBT) by trained therapists. The primary outcome measures were binge eating and purging frequency as assessed by interview at the end of treatment, and again at 3- and 12-month follow-ups. Secondary outcome measures included other bulimic symptoms and changes in mood. RESULTS: Retention in treatment was comparable for TV-CBT and FTF-CBT. Abstinence rates at end-of-treatment were generally slightly higher for FTF-CBT compared with TV-CBT, but differences were not statistically significant. FTF-CBT patients also experienced significantly greater reductions in eating disordered cognitions and interview-assessed depression. However, the differences overall were few in number and of marginal clinical significance. CONCLUSIONS: CBT for BN delivered via telemedicine was both acceptable to participants and roughly equivalent in outcome to therapy delivered in person. 相似文献

Older (mean age = 74.23) and younger (mean age = 33.50) participants recalled items from 6 briefly exposed household scenes either alone or with their spouses. Collaborative recall was compared with the pooled, nonredundant recall of spouses remembering alone (nominal groups). The authors examined hits, self-generated false memories, and false memories produced by another person's (actually a computer program's) misleading recollections. Older adults reported fewer hits and more self-generated false memories than younger adults. Relative to nominal groups, older and younger collaborating groups reported fewer hits and fewer self-generated false memories. Collaboration also reduced older people's computer-initiated false memories. The memory conversations in the collaborative groups were analyzed for evidence that collaboration inhibits the production of errors and/or promotes quality control processes that detect and eliminate errors. Only older adults inhibited the production of wrong answers, but both age groups eliminated errors during their discussions. The partners played an important role in helping rememberers discard false memories in older and younger couples. The results support the use of collaboration to reduce false recall in both younger and older adults. 相似文献

There is disagreement in the literature about whether a "positivity effect" in memory performance exists in older adults. To assess the generalizability of the effect, the authors examined memory for autobiographical, picture, and word information in a group of younger (17-29 years old) and older (60-84 years old) adults. For the autobiographical memory task, the authors asked participants to produce 4 positive, 4 negative, and 4 neutral recent autobiographical memories and to recall these a week later. For the picture and word tasks, participants studied photos or words of different valences (positive, negative, neutral) and later remembered them on a free-recall test. The authors found significant correlations in memory performance, across task material, for recall of both positive and neutral valence autobiographical events, pictures, and words. When the authors examined accurate memories, they failed to find consistent evidence, across the different types of material, of a positivity effect in either age group. However, the false memory findings offer more consistent support for a positivity effect in older adults. During recall of all 3 types of material, older participants recalled more false positive than false negative memories. 相似文献

Socially prescribed perfectionism (SPP) is often considered as a key risk factor for disordered eating (DE). However, current conceptualizations of SPP largely assume that this perfectionism pressure is non‐specific (i.e., a global pressure), despite research indicating that for females experiencing DE, female‐dominated groups impose this pressure (as a perceived norm). Furthermore, this relationship may be mediated by a negative reaction to this pressure, in the form of impulsivity (or negative urgency). To date, no research has investigated whether the relationship between SPP and DE is mediated by negative urgency, nor has there been research clarifying how in‐group identification relates to DE, independent of SPP and negative urgency. To address these gaps, we assessed these variables in 147 female dieters (Mage = 25.12 years, SD = 3.08) using a cross‐sectional design. Consistent with our hypotheses, negative urgency fully mediated the link between female‐based SPP and disordered eating, while female‐based in‐group affect (identification) was predictive of disordered eating (although the latter relationship was not sustained in a multiple regression model). These findings suggest that the SPP from other women may relate to DE through increasing negative urgency, and that the link between in‐group (female) affect and DE may be better explained by SPP's link to DE. 相似文献

Martine Nida-Rümelin (1996) argues that color science indicates that behaviorally undetectable spectrum inversion is possible and raises this possibility as an objection to functionalist accounts of visual states of color. I show that her argument does not rest solely on color science, but also on a philosophically controversial assumption, namely, that visual states of color supervene on physiological states. However, this assumption, on the part of philosophers or vision scientists, has the effect of simply ruling out certain versions of functionalism. While Nida-Rümelin is quite right to search for empirical tests for claims about the nature of visual states, philosophical issues remain pivotal in determining the correctness of these claims. 相似文献

Past research has suggested that negative affect may be a causal factor for eating disordered behaviors. More specifically, research has shown that anger appears to be one aspect of negative affect that is particularly relevant in bulimic patients. Previous studies have also shown that the relationship between negative affect and eating disordered behaviors may partially depend upon personality variables such as impulsivity. The present study examined whether the relationship between anger and eating disordered behaviors is moderated by impulsivity. Subjects completed an ecological momentary assessment (EMA) protocol for an average of 2 weeks. Findings revealed that overall antecedent anger level and the variability of antecedent anger predicted binge-eating episodes and that these relationships were moderated by participants' level of impulsivity. These findings suggest that personality variables impact the way that anger and eating behaviors relate. They also suggest that the variability of antecedent anger may be a fruitful avenue for future research for those interested in causal variables associated with bulimia nervosa. 相似文献

The contingency of composition 总被引:2,自引:2,他引:0
Ross P. Cameron 《Philosophical Studies》2007,136(1):99-121
There is widespread disagreement as to what the facts are concerning just when a collection of objects composes some further
object; but there is widespread agreement that, whatever those facts are, they are necessary. I am unhappy to simply assume
this, and in this paper I ask whether there is reason to think that the facts concerning when composition occurs hold necessarily.
I consider various reasons to think so, but find fault with each of them. I examine the theory of composition as identity,
but argue that the version of this doctrine that entails universalism is unwarranted. I consider the claim that the a priority
of such facts leads to their necessity, but give a defence of substantial contingent a priori truths. I ask whether the contingency
of such facts would lead to unwelcome possibilities, but argue that it does not. Next, I argue against the thought that the
Lewis–Sider argument against restricted composition might give us reason to accept the necessity of universalism. Lastly,
I respond to two objections from the 2006 BSPC. I conclude in favour of the contingency of the facts concerning when some
things compose some thing.

Both real-world category knowledge and instance-based sample data are often available as sources of inductive inference. In
three experiments using natural social categories, we test the influence of general category knowledge on the use of category
instances to make property inductions both to other category members and to others in the population. We find that a category’s
coherence—the extent to which its features are interrelated through prior knowledge (Murphy & Medin, 1985)—influences inductions
positively to new category members and negatively to the population. This effect of coherence is strongest with small as compared
with large samples of instances. The results are interpreted from both similarity and explanation-based perspectives. 相似文献
