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.

Common and specific cognitive deficits in schizophrenia: relationships to function

The goals of the present study were to assess the interrelationships among tasks from the MATRICS and CNTRACS batteries, to determine the degree to which tasks from each battery capture unique variance in cognitive dysfunction in schizophrenia, and to determine the ability of tasks from each battery to predict functional outcome. Subjects were 104 schizophrenia patients and 132 healthy control subjects recruited as part of the CNTRACS initiative. All subjects completed four CNTRACS tasks and two tasks from the MATRICS battery: Brief Assessment of Cognition in Schizophrenia Symbol Coding and the Hopkins Verbal Learning Test. Functional outcome was also assessed in the schizophrenia subjects. In both the patient and control groups, we found significant intercorrelations between all higher order cognitive tasks (episodic memory, goal maintenance, processing speed, verbal learning) but minimal relationships with the visual task. For almost all tasks, scores were significantly related to measures of functional outcome, with higher associations between CNTRACS tasks and performance-based measures of function and between one of the MATRICS tasks and self-reported functioning, relative to the other functioning measures. After regressing out variance shared by other tasks, we continued to observe group differences in performance among task residuals, particularly for measures of episodic memory from both batteries, although these residuals did not correlate as robustly with functional outcome as raw test scores. These findings suggest that there exists both shared and specific variance across cognitive tasks related to cognitive and functional impairments in schizophrenia and that measures derived from cognitive neuroscience can predict functional capacity and status in schizophrenia.     

Reduced susceptibility to confirmation bias in schizophrenia

Patients with schizophrenia (SZ) show cognitive impairments on a wide range of tasks, with clear deficiencies in tasks reliant on prefrontal cortex function and less consistently observed impairments in tasks recruiting the striatum. This study leverages tasks hypothesized to differentially recruit these neural structures to assess relative deficiencies of each. Forty-eight patients and 38 controls completed two reinforcement learning tasks hypothesized to interrogate prefrontal and striatal functions and their interaction. In each task, participants learned reward discriminations by trial and error and were tested on novel stimulus combinations to assess learned values. In the task putatively assessing fronto-striatal interaction, participants were (inaccurately) instructed that one of the stimuli was valuable. Consistent with prior reports and a model of confirmation bias, this manipulation resulted in overvaluation of the instructed stimulus after its true value had been experienced. Patients showed less susceptibility to this confirmation bias effect than did controls. In the choice bias task hypothesized to more purely assess striatal function, biases in endogenously and exogenously chosen actions were assessed. No group differences were observed. In the subset of participants who showed learning in both tasks, larger group differences were observed in the confirmation bias task than in the choice bias task. In the confirmation bias task, patients also showed impairment in the task conditions with no prior instruction. This deficit was most readily observed on the most deterministic discriminations. Taken together, these results suggest impairments in fronto-striatal interaction in SZ, rather than in striatal function per se.     

Traditional vs. nontraditional women and men's perceptions of the personalities and physiques of ideal women and men

Traditional and nontraditional women and men's perceptions of ideal people, in terms of both traits and physiques, were assessed using 80 male and 80 female Caucasian undergraduates as study participants. The data indicated that traditional women and men perceived the ideal male as mesomorphic and as having more instrumental than expressive traits. Nontraditional women and men also favored a mesomorphic physique for the ideal male, but they differed from traditionals in that they saw this mesomorphic male as being androgynous in regard to traits. Concerning the ideal female, traditional and nontraditional women and men preferred an androgynous physique, but they differed in their perceptions of the ideal personality for a woman. Traditional women and men perceived their ideal women as having more expressive than instrumental traits, whereas nontraditional women and men saw their ideal women as being androgynous in regard to traits. The results are discussed within the framework of Bem's gender schema and enculturated lens theories.     

American Psychiatric Association: Position Statement on Firearm Access,Acts of Violence and the Relationship to Mental Illness and Mental Health Services

The American Psychiatric Association, (“APA”), with more than 36,000 members at present, is the Nation's leading organization of physicians who specialize in psychiatry. APA provides for education and advocacy and develops policy through Position Statements. It promotes enhanced knowledge of particular topics relevant to psychiatric practice and patient care through Resource Documents. Since 1993, the APA has developed various positions and resource materials related to firearms and mental illness, incorporating evolving themes as new issues emerge. This paper reflects the APA's 2014 Position Statement on Firearm Access, Acts of Violence and the Relationship to Mental Illness and Mental Health Services.     

Wisdom in the Military Context

On the basis of the Berlin wisdom paradigm, we define wisdom in the military context as expert knowledge and judgment concerning in extremis military operations. We measured wisdom in the military context by asking participants to give advice to an inexperienced officer facing an in extremis operation; subsequently, we coded their responses. Data were provided by 74 senior noncommissioned officers (NCOs) in the U.S. defense forces. In support of convergent validity, wisdom in the military context was positively related to general objective wisdom and general self-assessed wisdom. Relationships of wisdom in the military context and general objective wisdom with Big Five personality characteristics were nonsignificant, whereas general self-assessed wisdom was positively related to extraversion, agreeableness, and openness to experience, and it was negatively related to neuroticism. The findings provide initial support for the validity of the new wisdom in the military context measure. We discuss several implications for future research and practice regarding wisdom in the military context.     

Impact of current grief on memory for past grief in spousal bereavement

This study examined the impact of changes in level of current grief over time on changes in memory for past grief. Following from previous work on the impact of current affective state on memory for past affectively salient events, bereaved individuals who underwent a greater reduction in grief over time were expected to show a similar pattern of changes in memory for past grief. A sample of conjugally bereaved participants completed measures of current grief and memory for past grief at the time of the loss of their spouse at each of the 2, 6, 13, and 30 month post-loss time periods. As predicted, those who reported greater reduction in grief over the course of the study were more likely to remember their past grief as progressively less severe relative to those who underwent less reduction in grief over time. A nonrecursive causal model analysis verified that changes in memory for past grief were explained by changes in current grief. These results were discussed in terms of contemporary reconstructive memory accounts of the effect of affective state on memory.
