Given the growing literature on the detrimental psychological consequences of NSSI, it is surprising that scarce research has focused on the permanent physical consequences of NSSI, scarring to one’s tissue (Burke et al. Psychiatry Research 228, 416–424, 2015; Lewis The Journal of Nervous and Mental Disease, 204(1), 33–35 2016). Indeed, with recent research suggesting that upwards of half of those with a history of NSSI bear scarring as a result of the behavior (Burke et al. Comprehensive Psychiatry, 65, 79–87 2016), the psychological implications of scarring are important to understand. Given preliminary literature suggesting that the vast majority of individuals who bear NSSI scars ascribe a great deal of meaning to their scarring, and that this meaning varies widely, a psychometrically sound scale is needed to comprehensively and systematically assess NSSI scar-related cognitions. The present study examined the psychometric properties of the Non-Suicidal Self-Injury Scar Cognition Scale (NSSI-SCS). A sample of 110 undergraduates with at least one scar from NSSI completed the NSSI-SCS as well as measures of concurrent and divergent validity. Exploratory Factor Analysis was conducted to determine the factor structure of the NSSI-SCS. Results indicated that a five-factor solution offered the best fit for the data. Psychometric analyses support the validity of the NSSI-SCS given evidence of concurrent validity, divergent validity, and reliability. Future research should examine the test-retest reliability of the NSSI-SCS, as well as its sensitivity to change, particularly in the context of treatment research. 相似文献

Purpose
In this investigation, we argue for why and how available intraclass correlation coefficients and other types of reliability estimates can be employed as sample-based reliability estimates within primary and meta-analytic studies when relationships between group-level phenomena are of interest.Design/Methodology/Approach
Group-level correlations and reliability estimates were obtained from 46 studies examining organizational climate–performance relationships. We illustrate how the group-level reliability estimates can be used to correct correlations for predictor and criterion unreliability. Procedures are presented for computing the sampling variances of individually corrected correlations that account for sampling error in the group-level reliability estimates.Findings
Support was found for the conservative nature of meta-analytic parameter estimates when group-level reliability information is sample-based as opposed to assumed population values. In addition, our analyses indicated that conclusions about substantive relationships between group-level variables can change based on availability of sample-based reliabilities within both primary and meta-analytic studies.Implications
Results from this study suggest that researchers should rely on sample-based meta-analytic procedures when examining the generalizability of group-level relationships. This study also demonstrates the importance of using all available reliability information and accounting for sampling error in the reliability estimates when conducting meta-analyses at the group level of analysis.Originality/Value
This study breaks ground by systematically examining the use of intraclass correlation coefficients as reliability estimates within group-level meta-analytic studies. Furthermore, illustrative analyses provide guidance to primary and meta-analytic researchers in regard to how to correct group-level correlations for unreliability in the predictor, criterion, or both whenever and in whatever proportions the artifact information is available.184.

Cognitive fatigue is common after strenuous cognitive effort. A large body of literature has implicated a network of brain areas in fatigue, including the basal ganglia and cortical areas including ventro-medal prefrontal cortex and anterior cingulate cortex (ACC). Furthermore, the ACC has been shown to be involved in processes such as error and conflict monitoring, outcome prediction, and effort processing. Thus, the ACC appears to be one common denominator between clinical work on fatigue and research on outcome prediction and effort. In the present study, we examined whether the same region of the ACC is activated during the processing of errors and fatigue. Cognitive fatigue was induced by having subjects perform a difficult working memory task, during which they rated on-task fatigue. Activation associated with error processing was determined by using error trials on the working memory task. After localizing the region engaged in error processing, we evaluated whether there was a relationship between BOLD activation of that region and on-task fatigue scores. The results showed that as subjects became more fatigued, they responded with longer latencies and increased accuracy for the more difficult task. Moreover, the ACC areas that were activated by error processing were also associated with fatigue. These results suggest that cognitive fatigue may be related to changes in effort and reward. We speculate that as the brain detects these changes, cognitive fatigue is generated as a way for the brain to signal itself that the effort required for the task no longer merits the rewards received for performing it. 相似文献

Generally, so-called control processes are thought to be necessary when we must perform one out of several competing actions.
Some examples include performance of a less well-practiced action instead of a well-practiced one (prepotency); learning a
new action (novelty); and rapidly switching from one action to another (task-switching). While it certainly is difficult to
perform the desired action in these circumstances, it is less clear that a separate set of processes (e.g., control processes)
are necessary to explain the observed behavior. Another way to approach the study of control processes is to investigate physiological
dependent measures (e.g., electrophysiological or neuroimaging measures). Although these offer another avenue of inquiry into
control processes, they have yet to furnish unambiguous evidence that control processes exist. While this might suggest that
there are no control processes, it is also possible that our methods are insufficiently sensitive to measure control processes.
We have investigated this latter possibility using tasks that are neuroanatomically distinct, though within the same modality
(vision). This approach did not yield evidence for a separable set of control processes. However, recent works using a task-switching
paradigm in which subjects switch between a visual and an auditory task suggest that switching both task and modality may
be importantly different than switching task within a given modality. This may represent a way forward in the study of control
processes. 相似文献

Increasing numbers of retirees spend their leisure time in the ever-growing number of gambling casinos in this country. For most older adults, casino gambling is a new form of excitement and entertainment. However, for some retirees, especially those vulnerable to depression from the changes and losses that can occur in aging, casino gambling can become disordered, problematic, and/or an addiction. Although prevalence studies have examined the incidence of problem gambling in other age groups, little attention has been directed to the impact of casino gambling on older adults. The authors discuss problem and pathological gambling in retired older adults, and provide clinical case examples of a growing number of older adults with problem gambling behaviors seen in an outpatient geriatric psychiatry clinic. Finally, they urge that an evaluation of gambling behaviors be a routine portion of geriatric clinical evaluations. 相似文献

Cherry pit primes Brad Pitt: Homophone priming effects on young and older adults' production of proper names 总被引:2,自引:0,他引:2
Abstract— This study investigated why proper names are difficult to retrieve, especially for older adults. On intermixed trials, young and older adults produced a word for a definition or a proper name for a picture of a famous person. Prior production of a homophone (e.g., pit) as the response on a definition trial increased correct naming and reduced tip-of-the-tongue experiences for a proper name (e.g., Pitt) on a picture-naming trial. Among participants with no awareness of the homophone manipulation, older but not young adults showed these homophone priming effects. With a procedure that reduced awareness effects (Experiment 2), prior production of a homophone improved correct naming only for older adults, but speeded naming latency for both age groups. We suggest that representations of proper names are susceptible to weak connections that cause deficits in the transmission of excitation, impairing retrieval especially in older adults. We conclude that homophone production strengthens phonological connections, increasing the transmission of excitation. 相似文献

The present study examined relationships among prenatal characteristics of 121 adolescent mothers-including cognitive readiness for parenting, intelligence, social support, and personal adjustment-and intellectual-linguistic development, social-emotional functioning, and adaptive behavior in their children at three years of age. Only 28% of the children scored within normal ranges on all three types of outcomes. Intellectual and linguistic delays were predicted best by prenatal measures of maternal Performance IQ and social support from extended family. Socioemotional problems were predicted best by maternal internalizing problems and social support from partner and friends. Adaptive behavior was associated with parenting style. Implications for the early identification of high-risk children--and associated intervention programs--are discussed. 相似文献
