We present a brief scale derived from the Nicotine Dependence Syndrome Scale (NDSS). We used a sample of 1.061 daily smokers, which was obtained from five Primary Care Health Centers, a Unit of Alcoholism, and a Smoking Cessation Unit. All smokers were evaluated with the NDSS and the SCID to assess nicotine dependence according to DSM-IV criteria. The results indicate the existence of a general factor of nicotine dependence according to the NDSS. We selected the items with a higher factor loading (>.50), obtaining a short scale of 6 items. With this brief scale, we obtained results similar to those of the total scale in the diverse variables (sociodemographic and smoking) of the study. Scale reliability is satisfactory (a= .79), the correlation between the short and the total scale is very high (r=.95, p<.001) and the short scale discriminates the smokers in terms of cigarette consumption and nicotine dependence, as assessed with the SCID. The operation under the ROC curve is excellent (area under the curve .84). The data indicate the usefulness of this brief scale (NDSS-S) to assess nicotine dependence in smokers. 相似文献

This instrumental study was designed to analyze the psychometric properties of the Spanish version of the Frost Multidimensional Perfectionism Scale (FMPS). The total sample was made up of 582 female college students, with a mean age of 21.68 (SD= 4.45). The results of confirmatory factor analysis identified the six-factor solution proposed by the original authors as the best factor structure, with acceptable fit indices. Cronbach's alpha coefficient was .93 for the FMPS total score and ranged from .74 to .91 for the subscales. Test-retest reliability suggested a good temporal stability of the FMPS total score [ICC= .89 (95% CI= .80-.94)] and its subscales. Results showed moderate to high associations between the Spanish version of the FMPS and other measures of perfectionism. The Spanish version of FMPS has shown satisfactory psychometric properties to be used in women. Future research should replicate these findings in broader samples, in clinical populations, and use longitudinal designs to determine whether perfectionism is a risk factor for psychopathology in women. 相似文献

Entrepreneurship education: relationship between education and entrepreneurial activity 总被引:1,自引:0,他引:1
The importance of entrepreneurial activity for the economic growth of countries is now well established. The relevant literature suggests important links between education, venture creation and entrepreneurial performance, as well as between entrepreneurial education and entrepreneurial activity. The primary purpose of this paper is to provide some insights about entrepreneurship education. The meaning of entrepreneurship education is explained, and the significant increase of these educational programmes is highlighted. Literature has been suggesting that the most suitable indicator to evaluate the results of entrepreneurship education is the rate of new business creation. However, some studies indicate that the results of such programmes are not immediate. Therefore, many researchers try to understand the precursors of venture creation, concluding that is necessary to carry out longitudinal studies. Based on an overview of the research published about the existing linkage of entrepreneurship education and entrepreneurial activity, the main topics studied by different academics are addressed. For the authors, the positive impact of entrepreneurship education puts a double challenge on governments in the future: the increased need of financial funds to support entrepreneurship education and the choice of the correct educational programme. 相似文献

Two main theories about metacognition are reviewed, each of which claims to provide a better explanation of this phenomenon,
while discrediting the other theory as inappropriate. The paper claims that in order to do justice to the complex phenomenon
of metacognition, we must distinguish two levels of this capacity—each having a different structure, a different content and
a different function within the cognitive architecture. It will be shown that each of the reviewed theories has been trying
to explain only one of the two levels and that, consequently, the conflict between them can be dissolved. The paper characterizes
the high-level as a rationalizing level where the subject uses concepts and theories to interpret her own behavior and the
low-level as a controlling level where the subject exploits epistemic feelings to adjust her cognitive activities. Finally,
the paper explores three kinds of interaction between the levels. 相似文献

In the present study, we investigate how spatial attention, driven by unisensory and multisensory cues, can bias the access of information into visuo-spatial working memory (VSWM). In a series of four experiments, we compared the effectiveness of spatially-nonpredictive visual, auditory, or audiovisual cues in capturing participants' spatial attention towards a location where to-be-remembered visual stimuli were or were not presented (cued/uncued trials, respectively). The results suggest that the effect of peripheral visual cues in biasing the access of information into VSWM depend on the size of the attentional focus, while auditory cues did not have direct effects in biasing VSWM. Finally, spatially congruent multisensory cues showed an enlarged attentional effect in VSWM as compared to unimodal visual cues, as a likely consequence of multisensory integration. This latter result sheds new light on the interplay between spatial attention and VSWM, pointing to the special role exerted by multisensory (audiovisual) cues. 相似文献

While previous research has suggested that adults with a history of childhood sexual abuse may be more prone to produce false memories, little is known about the consequences of childhood neglect on basic memory processes. For this reason, the authors investigated how a group of women with a history of childhood emotional neglect (CEN) and diagnosed with recurrent Major Depressive Disorder (MDD) performed on the Deese–Roediger–McDermott paradigm in comparison to control groups. The results indicated that women with MDD and CEN were actually less prone to produce false memories relative to both women with MDD but no CEN and healthy women without MDD and any form of childhood maltreatment. These findings were explained in terms of the inability to extract/retrieve gist memories that support false recognition of critical lures, an explanation that seems to fit well with emerging MRI findings linking childhood neglect to reduced volume of brain regions associated to memory function. 相似文献

Predictive testing protocols are intended to help patients affected with hereditary conditions understand their condition
and make informed reproductive choices. However, predictive protocols may expose clinicians and patients to ethical dilemmas
that interfere with genetic counseling and the decision making process. This paper describes ethical dilemmas in a series
of five cases involving predictive testing for hereditary ataxias in Cuba. The examples herein present evidence of the deeply
controversial situations faced by both individuals at risk and professionals in charge of these predictive studies, suggesting
a need for expanded guidelines to address such complexities. 相似文献

This research aims to identify distinct courses of depressive symptoms among middle-aged and older Americans and to ascertain how these courses vary by race/ethnicity. Data came from the 1995-2006 Health and Retirement Study which involved a national sample of 17,196 Americans over 50 years of age with up to six repeated observations. Depressive symptoms were measured by an abbreviated version of the Center for Epidemiologic Studies Depression scale. Semiparametric group based mixture models (Proc Traj) were used for data analysis. Six major trajectories were identified: (a) minimal depressive symptoms (15.9%), (b) low depressive symptoms (36.3%), (c) moderate and stable depressive symptoms (29.2%), (d) high but decreasing depressive symptoms (6.6%), (e) moderate but increasing depressive symptoms (8.3%), and (f) persistently high depressive symptoms (3.6%). Adjustment of time-varying covariates (e.g., income and health conditions) resulted in a similar set of distinct trajectories. Relative to White Americans, Black and Hispanic Americans were significantly more likely to be in trajectories of more elevated depressive symptoms. In addition, they were more likely to experience increasing and decreasing depressive symptoms. Racial and ethnic variations in trajectory groups were partially mediated by SES, marital status, and health conditions, particularly when both interpersonal and intrapersonal differences in these variables were taken into account. 相似文献

Personality disorders (PD) are a prevalent class of mental disorders that interfere with functioning and cause subjective distress while increasing the intensity and duration of Axis I clinical syndromes, and therefore assessing PD is important even when PDs are not the focus of treatment. The purpose of these studies was to develop and test a new Spanish version of a self-report measure of PD, the Wisconsin Personality Inventory-IV (WISPI-IV) that would be psychometrically equivalent to the English version while also maintaining the same interpersonal content, which is based on Benjamin's analysis of the PD criteria using her Structural Analysis of Social Behavior (SASB) model (1974). Study 1 participants completed the WISPI-IV twice over a two-week interval. For Study 2, participants from two sites in Spain and one site in Argentina completed Spanish versions of the WISPI-IV and other personality measures. SASB-analysis of the translated items showed high correspondence between the interpersonal content of the English version and the Spanish version demonstrating theoretical validation in relation to other PD measures. The Spanish WISPI-IV showed satisfactory reliability based on test-retest correlations and alphas for internal consistency. Study 2 showed the Spanish WISPI-IV had good convergent validity with the Spanish versions of the IIP and SCID-II and performed similarly to the English versions of these measures. Our goal in translating the WISPI-IV was to extend this measure to Spanish-speakers in language that would be understood by different Hispanic sub-groups, however research team members and subjects had a variety of suggestions for changes in item wording. This reflects the difficulty with creating a "neutral" Spanish version of any assessment given regional differences. 相似文献
