This article describes the initial development of a new measure of individual polychronicity, a construct indicating a preference for multitasking as opposed to performing only one task at a time. Following a brief review of past definitional issues, a revised definition is offered and a new measure of polychronicity—the Multitasking Preference Inventory (MPI)—is created based on this definition. Three studies describe the creation, pilot testing, and psychometric refinement of an initial pool of items (Study 1); a convergent and discriminant validity analysis (Study 2); and initial findings with respect to the criterion-related validity of scores on the MPI (Study 3). Together, these findings provide preliminary evidence for the reliability of scores on the MPI and the validity of the MPI in predicting variables relevant to multitasking.  相似文献

This work examines ways to make the best use of limited resources when selecting individuals to follow up in a longitudinal study estimating causal effects. In the setting under consideration, covariate information is available for all individuals but outcomes have not yet been collected and may be expensive to gather, and thus only a subset of the comparison participants are followed. Expressions in Rubin and Thomas (1996) Rubin, D. B. and Thomas, N. 1996. Matching using estimated propensity scores, relating theory to practice.. Biometrics, 52: 249264. [Crossref], [PubMed], [Web of Science ®] [Google Scholar] show the benefits that can be obtained, in terms of reduced bias and variance of the estimated treatment effect, of selecting comparison individuals well matched to those in the treated group compared with a random sample of comparison individuals. We primarily consider nonexperimental settings but also consider implications for randomized trials. The methods are illustrated using data from the Johns Hopkins University Baltimore Prevention Program, which included data collection from age 6 to young adulthood of participants in an evaluation of 2 early elementary-school-based universal prevention programs.  相似文献

Neuroimaging research indicates that human intellectual ability is related to brain structure including the thickness of the cerebral cortex. Most studies indicate that general intelligence is positively associated with cortical thickness in areas of association cortex distributed throughout both brain hemispheres. In this study, we performed a cortical thickness mapping analysis on data from 182 healthy typically developing males and females ages 9 to 24 years to identify correlates of general intelligence (g) scores. To determine if these correlates also mediate associations of specific cognitive abilities with cortical thickness, we regressed specific cognitive test scores on g scores and analyzed the residuals with respect to cortical thickness. The effect of age on the association between cortical thickness and intelligence was examined. We found a widely distributed pattern of positive associations between cortical thickness and g scores, as derived from the first unrotated principal factor of a factor analysis of Wechsler Abbreviated Scale of Intelligence (WASI) subtest scores. After WASI specific cognitive subtest scores were regressed on g factor scores, the residual score variances did not correlate significantly with cortical thickness in the full sample with age covaried. When participants were grouped at the age median, significant positive associations of cortical thickness were obtained in the older group for g-residualized scores on Block Design (a measure of visual-motor integrative processing) while significant negative associations of cortical thickness were observed in the younger group for g-residualized Vocabulary scores. These results regarding correlates of general intelligence are concordant with the existing literature, while the findings from younger versus older subgroups have implications for future research on brain structural correlates of specific cognitive abilities, as well as the cognitive domain specificity of behavioral performance correlates of normative gray matter thinning during adolescence.  相似文献

Solution‐focused brief counseling offers clients an opportunity to find solutions to problems and evoke cognitive change. This treatment modality is criticized for negating the emotional and spiritual aspects of client change. The authors propose that the inclusion of rituals in solution‐focused brief counseling can enhance the counseling experience for clients by encouraging meaningful cognitive, emotional, and spiritual change. A new model, Brief Solution Rituals, was developed to incorporate the use of rituals into solution‐focused counseling. The 6‐phase model, example clinical scenarios, and a case study are presented in this article. The strengths and potential limitations of the new model are discussed.  相似文献

Sleep disturbance and emotion dysregulation have been identified as etiologic and maintaining factors for a range of psychopathology and separate literatures support their relationships to anxiety, depression, PTSD, and alcohol dependence (AD) symptom severity. Previous studies have examined these relationships in isolation, failing to account for the high rates of comorbidity among disorders. It is not yet known whether these processes uniquely predict symptom severity in each of these domains. Participants were 220 patients in residential substance abuse treatment, who had experienced a potentially traumatic event and exceeded screening cutoffs for probable PTSD and problematic alcohol use. Controlling for emotion dysregulation and the interrelationships among the outcome variables, insomnia was uniquely associated with anxiety (B = .27, p < .001), depression (B = .25, p < .001), PTSD (B = .22, p < .001), and AD (B = .17, p = .01) symptom severity. Similarly, controlling for insomnia, emotion dysregulation was uniquely associated with anxiety (B = .40, p < .001), depression (B = .47, p < .001), PTSD (B = .38, p < .001), and AD (B = .26, p < .001) symptom severity. Insomnia and emotion dysregulation appear to be transdiagnostic processes uniquely associated with symptom severity across a number of different domains and might be important treatment targets for individuals with PTSD and AD.  相似文献

ObjectiveTrauma-focused psychological treatments are recommended as first-line treatments for Posttraumatic Stress Disorder (PTSD), but clinicians may be concerned that the good outcomes observed in randomized controlled trials (RCTs) may not generalize to the wide range of traumas and presentations seen in clinical practice. This study investigated whether Cognitive Therapy for PTSD (CT-PTSD) can be effectively implemented into a UK National Health Service Outpatient Clinic serving a defined ethnically mixed urban catchment area.MethodA consecutive sample of 330 patients with PTSD (age 17–83) following a wide range of traumas were treated by 34 therapists, who received training and supervision in CT-PTSD. Pre and post treatment data (PTSD symptoms, anxiety, depression) were collected for all patients, including dropouts. Hierarchical linear modeling investigated candidate moderators of outcome and therapist effects.ResultsCT-PTSD was well tolerated and led to very large improvement in PTSD symptoms, depression and anxiety. The majority of patients showed reliable improvement/clinically significant change: intent-to-treat: 78.8%/57.3%; completer: 84.5%/65.1%. Dropouts and unreliable attenders had worse outcome. Statistically reliable symptom exacerbation with treatment was observed in only 1.2% of patients. Treatment gains were maintained during follow-up (M = 280 days, n = 220). Few of the selection criteria used in some RCTs, demographic, diagnostic and trauma characteristics moderated treatment outcome, and only social problems and needing treatment for multiple traumas showed unique moderation effects. There were no random effects of therapist on symptom improvement, but therapists who were inexperienced in CT-PTSD had more dropouts than those with greater experience.ConclusionsThe results support the effectiveness of CT-PTSD and suggest that trauma-focused cognitive behavior therapy can be successfully implemented in routine clinical services treating patients with a wide range of traumas.  相似文献

Abstract

Old age is a stage in life in which numerous changes associated with loss can be expected to occur in major life domains. Deterioration of health; retirement; relocation; occupational and financial loss; loss of social roles, identity, status, and support; and the loss of spouse and significant others (siblings, friends) pose an ongoing threat to everyday functioning, forcing the individual to adapt. Thus, effective functioning in daily life represents a major developmental task for the aging (Bakes & Carstensen, 1996; Marsiske, Lang, Bakes, & Bakes, 1995). There is marked variability in adjustment among the elderly, and despite the numerous losses associated with aging, many elderly people are well adjusted and report experiencing high levels of well-being (George & Clipp, 1991;Wetle, 1990).  相似文献

ABSTRACT

What is the cognitive and emotional nature of fascination? Drawing on theories of cognitive and emotional interest, we explored the nature of visitor fascination (i.e., intense interest) at two High North museums in Norway. In Study 1, we found interesting and informative patterns related to which museum displays 20 teenage visitors experienced as particularly fascinating and why, along with the cognitive and affective qualities associated with those fascinations. We pursued these findings in more detail with 60 new visitors in Study 2. Through path modeling we were then able to capture the dynamics of when each of the following variables mattered to museum display experiences and in what ways: (1) display-relevant prior knowledge and interest, (2) the cognitive accessibility and emotional pleasure of museum display experiences, and (3) cognitive and affective interest outcomes. Implications for theories of interest and future research for exhibit design are discussed.  相似文献

This study examined which method is most effective in supporting parents to use positive guidance techniques, a lecture-based only parent training series or a lecture-based plus hands-on parent training series. Maternal characteristics of depression, stress level, and attitudes towards positive guidance were explored as possible moderators. In this sample of 49 mother–child dyads, results indicated that the cognitive understanding of the use of positive guidance over time of the participants in the lecture-based only versus the lecture-based plus hands-on groups did not significantly differ. However, both groups improved in their cognitive understanding of positive guidance over time. Results also indicated that the behavioral use of positive guidance over time of the participants in both groups significantly differed. Further investigation revealed that, although the two groups did not differ in their behavioral use of positive guidance before the program, the lecture-based plus hands-on group improved over time whereas the lecture-based only group did not. Depression, stress level, and attitudes towards positive guidance did not moderate the effects of being in either group on participants’ behavioral use of positive guidance. Findings showed that all participants gained a better understanding of effective parenting techniques, but a hands-on component in parent training programs may be necessary for parents to incorporate these strategies into their parenting behaviors. The results have implications for early childhood professionals working with parents to address children’s behavior issues, as well as for the design of parent-support programs.  相似文献
