Schizotypal experiences and depressive symptoms are quite common among adolescents, and have been considered as risk markers for schizophrenia-spectrum and mood disorders. The main goal of the present study was to analyze the relationship between schizotypal experiences and depressive symptoms in a community sample of non-clinical adolescents. The sample comprised a total of 1653 participants, 794 male (48%), with an average age of 15.94 years (SD = 1.23). Results showed that schizotypal traits and depressive symptoms were closely related at a subclinical level. Canonical correlation analysis indicated that the two sets of variables shared approximately 48% of the variance. The study of the dimensionality underlying the subscales of the self-reports revealed the presence of three components, namely: Depressive, Anhedonia and Reality Distortion. These results are convergent with previous studies conducted in both clinical and non-clinical samples, indicating overlap between schizotypal experiences and depressive symptoms.  相似文献

Although research on the prevention of drug use has shown that the effectiveness of programs depends partly on who applies them, the results of studies designed to clarify this issue are contradictory. This study compared the effects on smoking, in the short and medium term, of the implementation of two school-based prevention programs, depending on the type of applicator. The sample was made up of 200 seventh-grade students distributed among five experimental conditions: four of intervention, in which the programs were implemented by teachers from the school or by external psychologists, and one of control. The results show that teachers applying the Barbacana program and psychologists applying the Construyendo Salud (Building Health) program succeeded in reducing the incidence of cigarette smoking (BR-teachers 15%; C.S-psychologists 5%) and strengthening attitudes against smoking. An interaction effect between type of program and type of applicators was clearly observed.  相似文献

The School Social Climate Questionnaire (CECSCE) was adapted and applied. Subsequently, its psychometric proprieties were analyzed. The 1075 Chilean students who participated were assessed with the CECSCE and the School Violence Scale. The results showed that the CECSCE has a bifactorial structure, although there was also the possibility of a unifactorial structure. The CECSCE achieved satisfactory reliability and homogeneity indexes. The CECSCES scores were inversely related to the school violence rate. Lastly, differences by gender and educational level were analyzed. Given that there are differences in school climate perceptions in favor of girls, Chilean standards are presented in percentiles by gender. It can therefore be concluded that the CECSCE is sufficiently valid and reliable to be applied in Chile.  相似文献

Although women report feeling more pain than men, their pain is often underdiagnosed and undertreated. By proposing a gender-based theoretical conceptualisation, we argue that such sex-related biases may be enhanced or suppressed by contextual variables pertaining to the clinical situation, the perceiver or the patient. Consequently, we aimed to explore the moderator role of two clinically relevant variables in a chronic low-back pain (CLBP) scenario: diagnostic evidence of pathology (EP) and pain behaviours conveying distress. One-hundred and twenty-six female nurses (M?=?35.33, SD?=?7.64) participated in an experimental between-subjects design, 2 (patient's sex)?×?2 (EP: present vs. absent)?×?2 (pain behaviours: with vs. without distress). Independent variables were operationalised by vignettes depicting a patient with CLBP. Nurses judged the patient's pain on several dimensions: (1) credibility; (2) disability; (3) severity of the clinical situation; (4) psychological attributions and (5) willingness to offer support. Main findings showed that judgements of women's pain were influenced by EP, while judgements of men's pain were not. Moreover, nurses showed biases against men, but only in the presence of EP. The influence of distress cues was less consistent. Theoretical and practical implications are drawn.  相似文献

Under pressure, people often prefer what is familiar, which can seem safer than the unfamiliar. We show that such favoring of familiarity can lead to choices precisely contrary to the source of felt pressure, thus exacerbating, rather than mitigating, its negative consequences. In Experiment 1, time pressure increased participants' frequency of choosing to complete a longer but incidentally familiar task option (as opposed to a shorter but unfamiliar alternative), resulting in increased felt stress during task completion. In Experiment 2, pressure to reach a performance benchmark in a chosen puzzle increased participants' frequency of choosing an incidentally familiar puzzle that both augured and delivered objectively worse performance (i.e., fewer points obtained). Participants favored this familiar puzzle even though familiarity was established through unpleasant prior experience. This "devil you know" preference under pressure contrasted with disfavoring of the negatively familiar option in a pressure-free situation. These results demonstrate that pressure-induced flights to familiarity can sometimes aggravate rather than ameliorate pressure, and can occur even when available evidence points to the suboptimality of familiar options.  相似文献

This article describes Puerto Rican physicians’ personal and clinical utilization of complementary and alternative medicines (CAM), its effects, and use as they identified as either Spiritist, spiritual or religious. Semi-structured interviews were conducted with 74 doctors in Puerto Rico. Major themes and relationships among them were charted using the qualitative data analysis program MAXQDA, open coding and grounded theory. Thirty-one doctors spoke of CAM and its use as related to their spiritual or religious perspectives. Spiritual or Spiritist doctors were more inclined than religious doctors to utilize CAM. Seeking closer relationships with patients was related to a spiritually oriented goal of healing (as distinct from curing) as a reason to recommend CAM.  相似文献

The aim of the study was to analyze electromechanical delay in a ballistic movement of the superior limb. 10 male karate athletes and 9 nonathletes (without karate experience) performed a motor skill as fast and powerfully as possible, with impact on a makiwara (karate training instrument). For each participant, 10 choku-zuki performances were analyzed. Kinematics and surface electromyographic (EMG) activity of the anterior and posterior portions of deltoid, pectoralis major, latissimus dorsi, triceps brachii, and biceps brachii were recorded. Athletes had significantly shorter delay in arm flexion agonist muscles and significantly higher delay in arm flexion antagonist muscles and in forearm extension agonists. Results suggest that enhanced performance in athletes was mainly due to motor learning.  相似文献

Feeling empathy for one person in need while being aware of others may increase the motivational ambivalence between the motive of helping the one and the motive of helping the others, and such motivational ambivalence may reduce the helping directed to the person in need. To test these hypotheses we carried out three studies in which participants were faced with a real case of a child in need. In Study 1, empathy, awareness of others and motivational ambivalence were allowed to occur naturally and subsequently measured. In Study 2, empathy and awareness of others were experimentally manipulated, and motivational ambivalence measured. In Study 3, we tested how empathy and motivational ambivalence influenced an actual helping decision. Taken together, the results supported our two hypotheses. The present research offers insight into processes not previously considered in the research, but which may influence decisions about assistance to others in need.  相似文献

The stereotype of women’s limited parking skills is deeply anchored in modern culture. Although laboratory tests prove men’s average superiority in visuospatial tasks and parking requires complex, spatial skills, underlying mechanisms remain unexplored. Here, we investigated performance of beginners (nine women, eight men) and more experienced drivers (21 women, 27 men) at different parking manoeuvres. Furthermore, subjects conducted the mental rotation test and self-assessed their parking skills. We show that men park more accurately and especially faster than women. Performance is related to mental rotation skills and self-assessment in beginners, but only to self-assessment in more experienced drivers. We assume that, due to differential feedback, self-assessment incrementally replaces the controlling influence of mental rotation, as parking is trained with increasing experience. Results suggest that sex differences in spatial cognition persist in real-life situations, but that socio-psychological factors modulate the biological causes of sex differences.  相似文献

In order to examine the impulsive profile of a BPD sample with comorbid ADHD, adult patients who met criteria for BPD were assessed for ADHD with the CAADID and the WURS. A high rate of ADHD in the BPD sample was found, with sixty-nine (38.1%) BPD patients diagnosed as having comorbid adult ADHD. BPD-ADHD group had higher rates of general substance use disorder (59.4% vs. 38.4%), antisocial personality disorder (7.2% vs. 0.9%) and obsessive-compulsive personality disorder (21.7% vs. 6.3%). The BPD group without comorbid adult ADHD showed a higher rate of mood disorders (62.5% vs. 37.7%), panic disorders (54.5% vs. 23.1%) and benzodiazepine abuse (18.8% vs. 5.8%). Only in BPD patients without ADHD was comorbid avoidant personality disorder found. BPD patients could be distinguished in two clear subgroups related to the adult ADHD comorbidity. BPD-ADHD patients showed a more homogeneous and impulsive profile while BPD without ADHD comorbidity had more anxiety and depressive disorders.  相似文献
