Objective: The authors attempted to develop and validate a general distress index for a multidimensional psychological symptom/outcome measure used in over 300 college counseling centers with more than 100,000 cases annually: the Counseling Center Assessment of Psychological Symptoms (CCAPS). Method: Four models were compared for fit indices (n = 19,247): the existing first-order factor model (without a general factor), a second-order factor model, a bifactor model, and a single factor or “total score” model. In separate clinical and non-clinical samples, concurrent and divergent validity were examined using several well-established measures of psychological symptoms, as well as two-week test–retest and treatment utilization data. Results: Second-order and bifactor models which captured a single “distress” factor both exhibited good fit to the data relative to the baseline and “total score” model. Validity data indicated that factors adequately measured meaningful clinical onstructs. Conclusion: Both the bifactor and second-order models indicated the presence of a “distress index” comprised items across many of the CCAPS subscales. This distress scale has strong applicability for benchmarking the overall severity and complexity of patients at different centers, and can be used to help identify colleges and universities with areas of clinical strength, which can be studied to improve the field. Clinically, the distress index offers a parsimonious and efficient method for clinicians to monitor patients’ progress through treatment. 相似文献

New genetic tests reveal risks for multiple conditions simultaneously, although little is understood about the psychological factors that affect testing uptake. We assessed a conceptual model called the multiplex genetic testing model (MGTM) using structural equation modelling. The MGTM delineates worry, perceived severity, perceived risk, response efficacy and attitudes towards testing as predictors of intentions and behaviour. Participants were 270 healthy insured adults aged 25-40 from the Multiplex Initiative conducted within a health care system in Detroit, MI, USA. Participants were offered a genetic test that assessed risk for eight common health conditions. Confirmatory factor analysis revealed that worry, perceived risk and severity clustered into two disease domains: cancer or metabolic conditions. Only perceived severity of metabolic conditions was correlated with general response efficacy (β?=?0.13, p<0.05), which predicted general attitudes towards testing (β?=?0.24, p<0.01). Consistent with our hypothesised model, attitudes towards testing were the strongest predictors of intentions to undergo testing (β?=?0.49, p<0.01), which in turn predicted testing uptake (OR 17.7, β?=?0.97, p<0.01). The MGTM explained a striking 48% of the variance in intentions and 94% of the variation in uptake. These findings support use of the MGTM to explain psychological predictors of testing for multiple health conditions. 相似文献

In the context of purchasing ultimatums, consumers may dislike the freedom of choice that comes with proposing offers due to their awareness that the other party may have better information than they do and the fact that the attractiveness of outside alternatives is uncertain. Indeed, across three studies, we find that people prefer to receive rather than propose offers. In Study 1, proposers reached fewer agreements and experienced less favorable attitudes (e.g., satisfaction, fairness, recommendation intentions), particularly when their offers were rejected. In Study 2, proposers experienced more uncertainty and cognitive depletion as compared to receivers, again particularly if the proposed offer was rejected. In Study 3, role preferences were explained by the existence of higher regret in the proposer role, particularly if the proposed offer was rejected. We conclude with a consideration of the theoretical and practical implications of our research for scholars, customers, and service providers. 相似文献

This article introduces a simple survey method to distinguish between two types of variables that affect happiness—type A, which exerts an absolute effect on happiness, and type B, which affects happiness only through social context. The authors validate the method by comparing its findings with the findings of a theoretically superior but less practical experimental method, and use the method to identify the AB nature of a variety of naturally-occurring variables among both college students and people with work experience. We conclude by discussing the limitation of this method as well as its potential to inform policymakers about where to invest resources in order to improve people’s happiness over time. 相似文献

In the realm of self-regulation, recent work shows that the state of ego depletion can be vicariously transmitted from a target to a perceiver simply by imagining the perspective of a depleted target (i.e., vicarious depletion; Ackerman et al., 2009). The present study asked whether such vicarious effects can extend to the domain of self-regulatory recovery. In Experiment 1, depleted participants who took the perspective of someone engaging in a restorative activity showed recovered self-control on a later task. Experiments 2 and 3 expanded upon this effect by illustrating that such vicarious self-regulatory processes only emerge if the target is similar to the participant. Taken together, the present studies offer a powerful method by which mental resources can be replenished, and identify one critical boundary condition of its effectiveness. 相似文献

A key problem in statistical modeling is model selection, that is, how to choose a model at an appropriate level of complexity. This problem appears in many settings, most prominently in choosing the number of clusters in mixture models or the number of factors in factor analysis. In this tutorial, we describe Bayesian nonparametric methods, a class of methods that side-steps this issue by allowing the data to determine the complexity of the model. This tutorial is a high-level introduction to Bayesian nonparametric methods and contains several examples of their application. 相似文献

This meta-analysis examined over 40 years of research on interracial interactions by exploring 4 types of outcomes: explicit attitudes toward interaction partners, participants' self-reports of their own emotional state, nonverbal or observed behavior, and objective measures of performance. Data were collected from 108 samples (N = 12,463) comparing dyadic interracial and same-race interactions, predominantly featuring Black and White Americans. Effect sizes were small: Participants in same-race dyads tended to express marginally more positive attitudes about their partners (r = .07), reported feeling less negative affect (r = .10), showed more friendly nonverbal behavior (r = .09), and scored higher on performance measures (r = .07) than those in interracial dyads. Effect sizes also showed substantial heterogeneity, and further analyses indicated that intersectional, contextual, and relational factors moderated these outcomes. For example, when members of a dyad were the same sex, differences between interracial and same-race dyads in negative affect were reduced. Structured interactions led to more egalitarian performance outcomes than did free-form interactions, but the effects of interaction structure on nonverbal behavior depended on participant gender. Furthermore, benefits of intergroup contact were apparent: Differences in emotional state across dyadic racial composition disappeared in longer term interactions, and racial minorities, who often have greater experience with intergroup contact, experienced less negative affect in interracial interactions than did majority group members. Finally, there was a significant historical trend toward more egalitarian outcomes across dyadic racial composition for explicit attitudes and for nonverbal behavior; however, participants' emotional responses and performance have remained consistent. 相似文献

Research has documented that children and adolescents with attention-deficit/hyperactivity disorder (ADHD) are at increased
risk of substance use problems. Few studies, however, have focused on early-onset substance use. This study therefore investigated
how the two symptom dimensions of ADHD (hyperactivity/impulsivity and inattention) are associated with early-onset substance
use, the role of persistent ADHD for the association, and to what extent the association is influenced by genetic and environmental
factors. Twins (1,480 pairs) in the Swedish Twin Study of Child and Adolescent Development were followed from childhood to
adolescence. ADHD symptoms were measured at age 8–9 and age 13–14 via parent-report, whereas substance use was assessed at
age 13–14 via self-report. Results revealed that hyperactive/impulsive symptoms predicted early-onset “sometimes” tobacco
use (adjusted odds ratios, 1.12, for one symptom count), controlling for inattentive symptoms and conduct problem behaviors.
There is no independent effect of inattentive symptoms on early-onset substance use. Children with persistent hyperactivity/impulsivity
(defined as scoring above the 75th percentile at both time points) had a pronounced risk of both early-onset tobacco and alcohol
use (adjusted odds ratios from 1.86 to 3.35, compared to the reference group). The associations between hyperactivity/impulsivity
and early-onset substance use were primarily influenced by genetic factors. Our results indicated that hyperactivity/impulsivity,
but not inattention, is an important early predictor for early-onset substance use, and a shared genetic susceptibility is
suggested to explain this association. 相似文献
