Few personality traits are as socially relevant as impulsivity, but few self-report measures have been specifically developed for adolescents and children. The aim of the present study was to examine the psychometric properties of the Barratt Impulsiveness Scale version 11 (BIS-11) among a mixed-gender sample of 782 Portuguese youth (M = 15.87 years; SD = 1.72), in a school context. Confirmatory factor analysis revealed the expected 6-factor first-order structure, but the 3-factor second-order factorial structure did not present a good fit. Cross-gender measurement invariance was demonstrated only in terms of weak invariance. Nonetheless, the Portuguese adaptation of the BIS-11 demonstrated some generally acceptable psychometric properties of internal consistency, mean inter-item correlation, convergent validity, discriminant validity, and criterion-related validity of statistically significant associations with conduct disorder symptoms, alcohol abuse, drug use, and unprotected sex. The use of the BIS-11 among the male and female youth population is psychometrically justified, and it can be a useful measure to identify impulsive adolescents who are at considerable risk of personal injury and present a potential source of injury to others.  相似文献

The recent recession has generated a tremendous increase in unemployment rates in Spain. In this paper we use a very rich repeated cross-section dataset on workers’ job conditions, together with regional unemployment rates, to investigate whether peers’ unemployment affects individuals’ job satisfaction. We find that, once perceived job stability is controlled for, peers’ unemployment shows a positive effect on individuals’ wellbeing at work, greater and more precisely estimated for men and private-sector workers. The impact is highly non-linear and the greatest effect is found for unemployment rates exceeding 10 %. Interestingly, the results are robust to controlling for workforce selection.  相似文献

Extended contact has demonstrated its effectiveness in promoting more positive intergroup attitudes among children in previous experimental research. The current project evaluates the use of extended contact interventions involving story‐telling in two novel school settings: the United States (N = 213) and Italy (N = 222) among children aged 5–12 years. Findings indicate support for the effectiveness of the interventions in these two locations among younger minority and majority children but call into question the durability of positive outcomes. Applications and implications are discussed.  相似文献

Although it is widely recognized that adult attachment is associated with romantic relationship quality, the mechanisms involved remain poorly understood. This study aimed to investigate the mediating role of external and internal shame on the association between attachment and dyadic adjustment. A battery of self-report measures was completed by 228 Portuguese participants and a serial multiple mediation model was tested. Data showed that, in the population under study, attachment dimensions were associated with worse dyadic adjustment through high external and internal shame. Internal shame alone also mediated the association between attachment avoidance and dyadic adjustment. This study identifies a new putative mechanism linking adult attachment and intimate relationship functioning that may be targeted in couples therapy to promote a better dyadic adjustment and relationship functioning.  相似文献

With three studies, we investigated whether motivational states can modulate the formation of implicit preferences. In Study 1, participants played a video game in which they repeatedly approached one of two similar beverages, while disregarding the other. A subsequent implicit preference for the target beverage emerged, which increased with participants’ thirst. In Study 2, participants approached one brand of potato chips while avoiding the other: Conceptually replicating the moderation observed in Study 1, the implicit preference for the approached brand increased with the number of hours from last food intake. In Study 3, we experimentally manipulated hunger, and the moderation effect emerged again, with hungry participants displaying a higher implicit preference for the approached brand, as compared to satiated participants. In the three studies, the moderation effect was not paralleled in explicit preferences although the latter were affected by the preference inducing manipulation. Theoretical implications and open questions are discussed.  相似文献

Differentiating students with mathematical learning disabilities (MLD) from those with low achievement (LA) is still an unresolved issue. This study explored whether the specific combination of certain cognitive and numerical skills can classify students with MLD, with LA, and without MLD. In order to do this, an analysis was carried out of the performance of 756 Spanish students in grades two to six, on different numerical and cognitive tasks. Two factors were extracted using a principal component analysis of the tasks: a semantic-cognitive factor and a verbal-automation factor. The results obtained from comparing the groups showed that students with MLD and LA demonstrated significant differences in the semantic-cognitive factor, and that these differences were consistent across grade levels. In contrast, there were no differences between groups in the automatic-verbal factor. These results confirm that the groups are not only quantitatively different but also qualitatively different.  相似文献

Recent etiopathogenic theories of gastrointestinal conditions state that information processing biases can be a possible major factor involved in the aetiology and maintenance of these conditions. This exploratory study investigated the role of attention biases (AB) towards symptoms-related cues in gastrointestinal patients with respect to symptom maintenance, simultaneously taking into consideration the role of irrational beliefs. We included 32 patients diagnosed with gastrointestinal conditions. Patients completed a battery of psychological tests and an experimental task aimed to measure the preferential attention processing of linguistic stimuli related to gastrointestinal symptoms when they compete for attention resources with neutral stimuli. AB was positively related to irrational beliefs [r(31) = .376, p = .037] and analgesics use [r(32) = .518, p = .002], but not to self-report gastrointestinal symptoms [r(30) = ?.165, p = .382]. Irrational beliefs correlated with pain catastrophizing [r(31) = .373, p = .039], but not to gastrointestinal symptoms, pain intensity, visceral sensitivity or negative emotions; however, pain catastrophizing correlated with all of these. Taken together, our results suggest that core irrational beliefs action as general vulnerability factors that trigger specific implicit and explicit cognitive mechanisms (i.e., AB, pain catastrophizing) involved in the onset and maintenance of symptoms. Future experimental studies should test the robustness of these results in larger samples and aim to further advance our understanding of how cognitive factors interact and potentiate each other in generating and maintaining debilitating suffering.  相似文献

Several meta-analyses indicate that cognitive-behavioral therapy (CBT) via electronic/technological devices or applications (i.e., eCBT) is an effective alternative to standard therapist-delivered CBT for anxious adults. However, we know little about the efficacy of eCBT interventions for anxious children and adolescents. The present meta-analysis set out to investigate the efficacy of eCBT in comparison to standard CBT or waitlist control for anxious children and adolescents. Eight randomized controlled studies (N = 404 participants) that targeted anxiety at post-intervention and follow-up were included in the analysis. The results indicated that eCBT was as effective as standard CBT (g = .295) and more effective than waitlist (g = 1.410) in reducing anxiety symptoms. Moderation analyses revealed that anxious children and adolescents benefited the most from eCBT in the minimal therapist involvement condition (g = 2.682) in contrast to the significant therapist involvement group (g = .326). Furthermore, older participants seemed to extract greater clinical benefits from eCBT in contrast to younger participants (slope = .514). Current eCBT interventions for anxious children and adolescents appear to be promising, but require further investigation.  相似文献

Motivated by applications in software engineering, we propose two forms of combination of logics: synchronization on formulae and synchronization on models. We start by reviewing satisfaction systems, consequence systems, one-step derivation systems and theory spaces, as well as their functorial relationships. We define the synchronization on formulae of two consequence systems and provide a categorial characterization of the construction. For illustration we consider the synchronization of linear temporal logic and equational logic. We define the synchronization on models of two satisfaction systems and provide a categorial characterization of the construction. We illustrate the technique in two cases: linear temporal logic versus equational logic; and linear temporal logic versus branching temporal logic. Finally, we lift the synchronization on formulae to the category of logics over consequences systems.  相似文献
