This study compared the relative accuracy of (a) single Occupational Scale (OS) scores on the Strong Interest Inventory (SII) and (b) multiple-predictor scoring functions for discriminating members of nine occupations from people-in-general. The functions were constructed using discriminant function analysis with 4797 adults drawn from criterion samples for the 1985 SII. The analyses included Basic Interest Scale (BIS) scores only or combinations of OSs and BISs. Two subsequent analyses, one of which was cross-validation using 1302 young adults with little work experience, also were conducted. Results indicated that BIS-only functions yielded hit rates comparable to single OSs, and functions that combined OSs and BISs generally produced slight improvements in accuracy. These findings are potentially relevant for future SII scale development decisions. 相似文献

Evidence for shared heritable influences across domains of substance use suggests that some genetic variants influence broad risk for externalizing behaviors. Theories of externalizing psychopathology also suggest that genetic liability for substance use manifests as temperamental risk factors, particularly those related to behavioral disinhibition, during adolescence. The cholinergic muscarinic receptor 2 gene (CHRM2) is a promising candidate for studying genetic influences on broad-based risk for externalizing traits. This study examined a candidate CHRM2 polymorphism (rs1455858) in relation to substance use and personality measures of disinhibition in a sample of high-risk adolescents (n?=?124). Bivariate analyses and structural equation modeling (SEM) evaluated associations of rs1455858 with measures of drug involvement (alcohol, tobacco and marijuana) and disinhibition (indexed by impulsivity and sensation seeking scores). Bivariate analyses showed significant associations of CHRM2 with several behavioral phenotypes. In SEM analyses CHRM2 related significantly to latent measures of substance use and disinhibition; additionally, disinhibition mediated the association of CHRM2 with substance use. These results suggest that CHRM2 variants are potentially relevant for adolescent substance use and that temperamental risk factors could contribute to these associations. 相似文献

The current study tested the hypothesis that experiencing a calling to a particular career would relate positively to work-related outcomes, and that these relations would be mediated by career commitment. Using a sample of 370 employees representing diverse occupations at a Western research university, results supported these hypotheses as calling moderately correlated with career commitment, job satisfaction, and organizational commitment and weakly correlated with withdrawal intentions. Career commitment was found to fully mediate the calling–job satisfaction relation, partially mediate the calling–organizational commitment relation, and act as a suppressor in the relation between calling and withdrawal intentions; calling was associated with somewhat greater withdrawal intentions once a person's level of career commitment was taken into consideration. These results suggest that career commitment may represent a critical link between calling and work-related well-being. Implications for research and practice are explored. 相似文献

Color singletons that are irrelevant to locating a visual target do not typically capture attention if visual search is effortful. In contrast, when search is efficient color singletons are often found to capture attention. Such distraction by a color singleton can be modulated by single-task vs. dual-task manipulations when visual search is efficient. This is due, presumably, to the increased cognitive load in the dual-task condition, which interferes with top-down attentional control. This study investigated whether capture by a color singleton is also modulated by single-task vs. dual-task manipulations when visual search was effortful. The results of three experiments revealed that attentional capture effects were absent in a single-task condition and were present in a dual-task condition, but only when the identity of the color singleton is not associated with the target response-set. When the identity of the color singleton was relevant to the response-set it captured attention in both the single-task and in dual-task conditions. 相似文献

This editorial overview provides an introduction to the Suicide and Life‐Threatening Behaviors Special Issue: “Analytic and Methodological Innovations for Suicide‐Focused Research.” We outline several challenges faced by modern suicidologists, such as the need to integrate different analytical and methodological techniques from other fields with the unique data problems in suicide research. Therefore, the overall aim of this issue was to provide up‐to‐date methodological and analytical guidelines, recommendations, and considerations when conducting suicide‐focused research. The articles herein present this information in an accessible way for researchers/clinicians and do not require a comprehensive background in quantitative methods. We introduce the topics covered in this special issue, which include how to conduct power analyses using simulations, work with large data sets, use experimental therapeutics, and choose covariates, as well as open science considerations, decision‐making models, ordinal regression, machine learning, network analysis, and measurement considerations. Many of the topics covered in this issue provide step‐by‐step walkthroughs using worked examples with the accompanied code in free statistical programs (i.e., R). It is our hope that these articles provide suicidologists with valuable information and strategies that can help overcome some of the past limitations of suicide research, and improve the methodological rigor of our field. 相似文献

The Fisher-Pitman permutation test can detect any type of difference between two samples: hence, a significant Fisher-Pitman permutation test does not necessarily provide evidence for a difference in means. It is possible, however, to test separately for differences in means and variances. Here, we present a recently proposed two-stage procedure to decide whether there are differences in means or variances that can be applied when samples may come from nonnormal distributions with possibly unequal variances. 相似文献

Sometimes people believe that a run of similar independent events will be broken (belief in thegambler’s fallacy) but, other times, that such a run will continue (belief in the hot hand). Both of these opposite inductions have been explained
as being due to belief in a law of small numbers. We argue that one factor that distinguishes these phenomena is people’s
beliefs about the randomness of the underlying process generating the events. We gave participants information about a streak
of events but varied the scenarios in such a way that the mechanism generating the events should vary in how random the participants
would judge it to be. A manipulation check confirmed our assumptions about the scenarios. We found that with less random scenarios,
the participants were more likely to continue a streak. 相似文献
