Effect of an aerobic training program as complementary therapy in patients with moderate depression

The aim of this study was to assess the effects of an aerobic training program as complementary therapy in patients suffering from moderate depression. 82 female patients weredivided into a group that received traditional pharmacotherapy (Fluoxetine 20 mg) and a group that received pharmacotherapy plus an aerobic training program. This program was carried out for eight consecutive weeks, three days per week, and included gymnastics, dancing, and walking. Depressive symptoms were measured with the Beck Depression Inventory and the ICD-10 Guide for Depression Diagnosis, both administered before and after treatments. The results confirm the effectiveness of the aerobic training program as a complementary therapy to diminish depressive symptoms in patients suffering from moderate depression.     

Chilean validation of the Posttraumatic Stress Disorder Checklist-Civilian version (PCL-C) after the earthquake on February 27, 2010

Posttraumatic stress disorder (PTSD) is an anxiety disorder in which an individual re-experiences a traumatic event, avoids situations related to it, and shows excessive arousal. The disorder appears after experiencing a life-threatening event, such as a war or a natural disaster. Thus, the validation of tests which assess the disorder after the earthquake on February 27, 2010, in Chile is crucial for its evaluation and subsequent intervention. The present study includes psychometric data for the Posttraumatic Stress Disorder Checklist-Civilian version (PCL-C) on a sample of 509 survivors of the disaster. Values indicate good psychometric properties of the questionnaire.     

Are cross-cultural comparisons of personality profiles meaningful? Differential item and facet functioning in the Revised NEO Personality Inventory

Measurement invariance is a prerequisite for confident cross-cultural comparisons of personality profiles. Multigroup confirmatory factor analysis was used to detect differential item functioning (DIF) in factor loadings and intercepts for the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992) in comparisons of college students in the United States (N = 261), Philippines (N = 268), and Mexico (N = 775). About 40%-50% of the items exhibited some form of DIF and item-level noninvariance often carried forward to the facet level at which scores are compared. After excluding DIF items, some facet scales were too short or unreliable for cross-cultural comparisons, and for some other facets, cultural mean differences were reduced or eliminated. The results indicate that considerable caution is warranted in cross-cultural comparisons of personality profiles.     

Authentic leadership. Concept and validation of the ALQ in Spain

This study presents the validation of the Authentic Leadership Questionnaire (ALQ) in a sample of more than 600 Spanish employees. This questionnaire measures four distinct but related substantive components of authentic leadership. These components are: self-awareness, relational transparency, balanced processing, and internalized moral perspective. Structural equation modeling confirmed that the Spanish version of ALQ has high reliability and predictive validity for important leadership outputs such as perceived effectiveness of leadership, followers' extra effort and satisfaction with the leader.     

Factor structure and reliability of the Spanish adaptation of the Children's Yale-Brown Obsessive-Compulsive Scale--Self Report (CY-BOCS-SR)

The aim of this study was the adaptation to Spanish of the ?Children's Yale-Brown Obsessive-Compulsive Scale--Self Report? (CY-BOCS-SR), one of the most frequently utilized scales in the assessment of obsessive-compulsive behaviors. After its translation to Spanish, its factor invariance in boys and girls, reliability, and relationship with the children's age were examined. Lastly, normative data for this Spanish version are presented. The sample comprised 1,706 children and adolescents from the general population. Results show that the factor composition of the CY-BOCS-SR does not present a very good fit to the usual scoring of three scales were observed: Obsession Severity, Compulsion Severity, and total score. Results also show that the factor validity and reliability of the CY-BOCS-SR improve remarkably if items related to Resistance to Obsessions and Compulsions are considered a different factor from Severity. It is concluded that the Spanish version of the CY-BOCS-SR has similar psychometric characteristics as the original English version.

先天视觉经验缺失对颜色认知的影响：一项ERP研究

感觉与认知是否是相互独立的？本研究通过对比先天盲被试与明眼被试在进行物体颜色判断时的行为反应和神经电生理信号变化,探讨视觉经验缺失对颜色认知的影响。结果发现,先天盲被试具有一定的颜色知识,但其水平低于明眼被试;两组被试都出现了由颜色不匹配所诱发的N400效应,且都表现出左半球优势;但是盲人组的N400效应大于明眼组,盲人组的N400反应潜伏期小于明眼组。该结果说明,直接的视觉经验是颜色认知的充分条件而非必要条件。     

Acculturation Preference Profiles of Spaniards and Romanian Immigrants: The Role of Prejudice and Public and Private Acculturation Areas

The main goal of this study was to identify acculturation preference profiles using cluster analysis in public and private areas of culture in the host and immigrant populations, and to find out the relationship between these profiles and prejudice levels. Four hundred and ninety-nine Spaniards and 500 Romanians participated in a survey. The sampling of Spaniards was multistage random and the sampling of Romanians was by quota. The results confirm our predictions. Romanians who are less prejudiced against Spaniards prefer assimilation in public areas and integration in private areas. Romanians who are more prejudiced against Spaniards prefer integration in public areas and separation in private areas. Spaniards who are less prejudiced against Romanians prefer integration in both public and private areas. Spaniards who are more prejudiced against Romanians prefer assimilation in both areas.     

Race-Related Differences in the Experiences of Family Members of Persons with Mental Illness Participating in the NAMI Family to Family Education Program

Families play an important role in the lives of individuals with mental illness. Coping with the strain of shifting roles and multiple challenges of caregiving can have a huge impact. Limited information exists regarding race-related differences in families’ caregiving experiences, their abilities to cope with the mental illness of a loved one, or their interactions with mental health service systems. This study examined race-related differences in the experiences of adults seeking to participate in the National Alliance on Mental Illness Family-to-Family Education Program due to mental illness of a loved one. Participants were 293 White and 107 African American family members who completed measures of problem- and emotion-focused coping, knowledge about mental illness, subjective illness burden, psychological distress, and family functioning. Multiple regression analyses were used to determine race-related differences. African American caregivers reported higher levels of negative caregiving experiences, less knowledge of mental illness, and higher levels of both problem-solving coping and emotion-focused coping, than White caregivers. Mental health programs serving African American families should consider targeting specific strategies to address caregiving challenges, support their use of existing coping mechanisms and support networks, and increase their knowledge of mental illness.
