Availability of brief, self-report measures to be used as screening instruments is crucial to detect correctly youth with social anxiety disorder and therefore, reach those otherwise under-detected and under-treated. A previous study revealed that the Social Phobia Inventory (SPIN) was potentially an appropriate measure for screening social anxiety among US adolescents. However, there is a lack of information concerning its properties as a screening test in other cultures and languages. This is the main objective of this study, although further validity of the scale is provided as well. The sample consisted of 192 adolescents (a sample composed of 114 subjects with a principal diagnosis of social anxiety disorder; and a group consisting of 78 subjects with no diagnosis of social phobia). Results suggest that the Social Phobia Inventory has demonstrated good psychometric properties and indeed may be used as a screening tool in Spanish-speaking adolescents.  相似文献

大鼠作业成绩与脑内亮氨酸脑啡肽含量变化的相关性研究   总被引:1,自引:0,他引:1  
本工作采用穿梭式电击回避反应法和脑啡肽的放射免疫测定法,分析比较了大鼠作业成绩与脑内壳氨酸脑啡肽(Leu-enkephalin,LEK)含量的关系,在本实验条件下,观察到作业成绩不良组纹状体内LEK含量显著高于成绩优良组和对照组,并由实验证明,它们之间的差异不是由于在实验中接受电击的次数或电击总量不同造成的。这一结果提示,内源性亮氨酸脑啡肽可能参与记忆获得的调制。  相似文献

大学生A型行为类型及其学业情绪特点   总被引:1,自引:0,他引:1  
用A型行为类型量表和大学生一般学业情绪问卷对218名大学生进行了调查。结果发现:被调查大学生中A型行为者(A和A^-)约占25%。大学生的学业情绪以正性情绪为主,A型行为者的比例和学业情绪的得分在性别、年级、专业变量上无显著差异。不同行为类型者学业情绪的特点:B型者(B或B^-)的羞愧、气愤、厌烦、焦虑、自豪、希望、愉快情绪均明显低于A型者(A或A^-);B型者(B或B^-)的羞愧、气愤情绪明显低于极端中间型者;TH得分高者负性情绪多而不能放松;CH得分高的学生既有羞愧和气愤,又有自豪和希望。  相似文献

Employees' innovative work behavior (IWB) is one of the key factors in improving organizational competitiveness. Previous studies show that challenge and hindrance stress can impact employees' IWB, but our understanding of the exact mechanism underlying the impact is still limited. The present study employed four scales (Challenge and Hindrance Stress Scale, Thriving at Work Scale, Chinese Emotional Exhaustion Scale, and Employee Innovative Behavior Scale) to collect questionnaire data from 789 employees in diverse organizations via an online platform. A two-path mediation model was constructed. The results show that: (a) challenge stress positively predicted thriving at work and IWB; (b) thriving at work played a partial mediation effect between challenge stress and IWB; (c) hindrance stress negatively predicted thriving at work and positively predicted emotional exhaustion; and (4) hindrance stress did not directly impact IWB while thriving at work and emotional exhaustion were main mediators in the relationship between hindrance stress and IWB. These findings suggest that employees should sensibly cope with different work stresses, while managers should plan work tasks scientifically and give employees adequate opportunities to learn and rest in order to keep them in a positive state to solve problems and work creatively.  相似文献

Two studies compared hemispatial bias for perceiving chimeric faces in patients having either atypical or typical depression and healthy controls. A total of 245 patients having major depressive disorder (MDD) or dysthymia (164 with atypical features) and 115 controls were tested on the Chimeric Faces Test. Atypical depression differed from typical depression and controls in showing abnormally large right hemisphere bias. This was present in patients having either MDD or dysthymia and was not related to anxiety, physical anhedonia, or vegetative symptoms. In contrast, patients having MDD with melancholia showed essentially no right hemisphere bias. This is further evidence that atypical depression is a biologically distinct subtype and underscores the importance of this diagnostic distinction for neurophysiologic studies.  相似文献

Olivopontocerebellar atrophy (OPCA) is a still debated condition, of which motor disruption is the most common feature. A high incidence of associated mood disorders may exist, but there are few studies on concomitant cognitive impairment. Our aim was to assess whether there is reading and writing disruption in olivopontocerebellar atrophy (OPCA). 6 patients were administered different reading and writing tasks. Scores were then compared to those obtained by healthy volunteers. There was an evident impairment in reading and writing execution in our patients compared to those of the control group. On the contrary, no difference could be found in abstraction, problem-solving, and memory tasks. We discuss the results, debating the role of the cerebellum in the conscious process of cognition or in ocular movement control (necessary for reading and writing fluidity and effective execution) and in the dynamic activation of all the cerebral cortex mediated by the diffuse projection to the reticular system.  相似文献
