The aim of this study was to examine the comorbidity between the SCARED anxiety factors and depressive symptoms in 8-12-year-old children. Participants were 792 girls and 715 boys, who completed: the 41-ítem version of the Screen for Child Anxiety Related Emotional Disorder (SCARED), the Children's Depression Inventory (CDI) and a Socio-demographic questionnaire. Of the sample, 47% showed anxiety symptoms and 11.5% showed depressive symptoms. Heterotypic comorbidity was 82% in children at risk of depression and 20% in children at risk of anxiety. Homotypic Comorbidity between anxiety factors was 87%. Homotypic comorbidity and heterotypic comorbidity were high; their early detection will prevent the continuity of an anxious disorder and the development of depression.  相似文献

We studied the effect of emotion generated by IAPS (International Affective Picture System) pictures on incidental recognition of these pictures for short retention periods (15 min). Memorization distraction tasks and reaction time tasks were used together with short exposure times (2 seconds per picture) in order to prevent a high recognition rate that would impede testing for the effect of emotion on discrimination parameters (A′) and response bias (B′′D) (ceiling effect). We used 80 pictures representing the medium and high levels of two-dimensional emotional space. The results showed greater discrimination and a more conservative response style to unpleasant and medium arousal level pictures. These pictures produced higher confidence and lower response times in the recognition phase. The results can be explained by the negative content of the pictures and activation level effects on attentional processing and memory, and can be interpreted as a phenomenon that is evolutionarily adaptive.  相似文献

The aim of this trial has been to determine the efficacy of a group memory training method. The experimental group was compared to a placebo group (health education) or to a control group (waiting list). Forty‐five adults between the ages of 60 and 70 years (M = 66.9) were recruited by placing notices in senior citizen community centres, which encouraged people with memory problems to participate in the study. Data were collected at baseline, 1 week, and 6 months after the intervention. The efficacy of the training was evaluated by measures of objective and subjective everyday memory performance. After intervention, the experimental group participants showed an increase in objective memory performance (d = 1.95). The effect size was even higher at 6 months after intervention (d = 2.88). Further, their subjective experience related to everyday memory slips decreased (d = ?0.52). The memory training method was effective in improving everyday memory in older people with some cognitive decline. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

Abstract: I discuss the account of logical consequence advanced in Wittgenstein's Tractatus. I argue that the role that elementary propositions are meant to play in this account can be used to explain two remarkable features that Wittgenstein ascribes to them: that they are logically independent from one another and that their components refer to simple objects. I end with a proposal as to how to understand Wittgenstein's claim that all propositions can be analysed as truth functions of elementary propositions.  相似文献

The pre-post treatment change of 112 patients in two therapeutics Spanish communities is described. The Addiction Severity Index (ASI) was used at intake and at the end of the treatment program. Results of the treatment program were evaluated by applying composite scores (CS) of the ASI, and the evolution of each patient was evaluated using the Reliable Change Index (RCI). 69.7% of the sample completed treatment, and 30.3% dropped out prematurely. At intake, the percentage of people who could improve in the different areas of the ASI ranged between 35.1% for alcohol consumption and 95.3% for family relationships. At the follow-up, the percentage of subjects who showed significant statistical improvements in the different areas varied between 7.9% in family relations and 66.7% in alcohol consumption. The percentage of patients who deteriorated was less than 10% for all variables. Implications for further research and clinical practice are commented upon.  相似文献

M.Div. programs sequence curriculum in order to cumulatively build competencies for wise, faithful, reflective, appropriate and effective ministerial practices. That is why the introductory preaching course typically is positioned somewhere near the middle of the program. The author of this article discovered that students who, in the semester immediately preceding the introductory preaching course, were apprenticed in the art of critical theological reflection on previously preached sermons entered the introductory course more eager, with more finely attuned expectation levels, and with anxiety levels that promoted rather than hampered learning.  相似文献

RESUMEN

En este artículo los autores aportan una visión de lo que se entiende por psicología del testimonio. Condensan los estudios sobre los procedimientos policiales de recuerdo de personas que se desarrollaron simulando las condiciones reales lo más exactamente posible, resaltando la capacidad de la ciencia psicológica en un campo “relativamente” nuevo y, a todas luces, aplicado. Comienzan por delimitar el área y describir los procedimientos policiales más difundidos en los diferentes países, comentando a continuación los resultados de las investigaciones psicológicas sobre los instrumentos genéricamente llamados “retratos-robot” y que, principalmente, han sido realizados en las universidades de Aberdeen (Escocia) y Houston (USA). En el último apartado sintetizan los datos más relevantes y finalizan subrayando la utilidad de la Psicología en este ámbito y la importancia de diseños experimentales cercanos a la realidad.  相似文献

Schools remain among the most frequent providers of children’s mental health services, particularly in low-income urban settings. Several decades of research have focused on training teachers to implement evidence-based interventions for minimizing disruptive behavior. Studies consistently demonstrate robust improvements in student behavior and learning; however, the impact on teachers’ work-related stress or satisfaction is not well understood. Six urban, high-poverty elementary schools were randomly assigned to a school mental health services model (Links to Learning; L2L) for referred, disruptive students or to services and professional development as usual (SAU). Teachers (n = 71, K-4 general education teachers) in L2L schools participated in professional development and consultation in two universal and two targeted interventions to reduce disruptive behaviors and promote learning. Teachers (n = 65) in SAU schools participated in professional development as usual. Multiple regression models examined teacher reports of individual-level self-efficacy, classroom-level student functioning, and school-level organizational health as predictors of stress and satisfaction. Findings revealed no significant difference between conditions on teacher work-related stress or satisfaction. Organizational health was the strongest predictor of stress and satisfaction. Training on and implementation of evidence-based classroom interventions did not appear to significantly impact teachers’ work-related stress or satisfaction. Instead, findings point to organizational climate and teacher connectedness as potential levers for change, supporting prior work on teacher stress and satisfaction in schools. The significance of targeting organizational factors may be particularly significant in urban school districts.  相似文献

El Salvador, as a country of the Northern Triangle, exhibits significantly higher rates of crime and delinquency than the rest of the Latin American countries (World Bank 2011). Mass media portray transnational youth gangs in marginalized communities in Central American nations, such as El Salvador, as one of the main factors responsible for the high levels of violence. Few studies have empirically studied active youth gang members and high-risk youth in these contexts. Among the studies that have accessed active youth gang members, the focus has been on problem behaviors and risk factors analyses; little is known about what variables appear to serve as protective factors for these youth. Based on a cross-sectional sample of high-risk youth and youth gang members (n = 184) between the ages of 13 and 25 living in 10 urban communities in San Salvador, this study used linear regression modeling to analyze protective factors for three outcome variables: aggression, violence, and delinquency. Results reveal that self-control and school motivation act as important protective factors across the three domains, while school behavior is a protective factor of aggression and delinquency. Implications for community-based prevention and harm reduction policies are discussed.  相似文献
