Clothing use may be a behavioral avoidance strategy for individuals with body dissatisfaction and eating pathology. The authors administered the Body Image Avoidance Questionnaire (J. C. Rosen, D. Srebnik, E. Saltzberg, & S. Wendt, 1991), the Bulimia Test-Revised (M. Thelen, J. Farmer, S. Wonderlich, & M. Smith, 1991), and the Body dissatisfaction subscale of the Eating Disorder Inventory (D. M. Garner, M. P. Olmstead, & J. Polivy, 1983) to undergraduate college women from two universities (N = 540). Results indicated that women who were more dissatisfied with their bodies (beta = .396) and had greater disordered eating behaviors (beta = .378) were more likely to engage in clothing-related appearance-management behaviors (p < .001), including wearing apparel to camouflage their bodies; avoiding revealing, brightly colored, or tightly fitting clothing; and avoiding shopping for clothing. These findings suggest that the presence of certain clothing-related appearance-management behaviors may be a warning sign that an individual is at risk for developing an eating disorder or may currently have an eating disorder. 相似文献

Resulting from a community-identified need for a well-validated indicator of caregiving difficulties for use in practice settings, a brief form of the Atypical Maternal Behavior Instrument for Assessment and Classification System (AMBIANCE) was developed for use as a screening instrument. Prior to its dissemination, this study aimed to assess the feasibility, reliability, and validity of the AMBIANCE-Brief. Adolescent mother–infant dyads (N = 69) participated in the Strange Situation Procedure, as well as play sessions with and without toys. Maternal disrupted caregiving was coded from the play sessions using the AMBIANCE and AMBIANCE-Brief. The AMBIANCE-Brief demonstrated convergent validity with the AMBIANCE in the play session with toys (r = .65, p < .001) and without toys (r = .61, p < .001). Concurrent validity of the AMBIANCE-Brief was also demonstrated in relation to infant attachment disorganization in the play session with toys (r = .36, p < .05) and without toys (r = .32, p < .01). These findings suggest a shorter protocol for assessing disrupted caregiving may be feasible and valid for use in community settings. Future studies are in progress to train community practitioners in the use of the AMBIANCE-Brief and to evaluate their reliability. 相似文献

Interactions with neocortical memory systems may facilitate flexible information processing by hippocampus. We sought direct evidence for such memory influences by recording hippocampal neural responses to a change in cognitive strategy. Well-trained rats switched (within a single recording session) between the use of place and response strategies to solve a plus maze task. Maze and extramaze environments were constant throughout testing. Place fields demonstrated (in-field) firing rate and location-based reorganization [Leutgeb, S., Leutgeb, J. K., Barnes, C. A., Moser, E. I., McNaughton, B. L., & Moser, M. B. (2005). Independent codes for spatial and episodic memory in hippocampal neuronal ensembles. Science, 309, 619-623] after a task switch, suggesting that hippocampus encoded each phase of testing as a different context, or episode. The task switch also resulted in qualitative and quantitative changes to discharge that were correlated with an animal's velocity or acceleration of movement. Thus, the effects of a strategy switch extended beyond the spatial domain, and the movement correlates were not passive reflections of the current behavioral state. To determine whether hippocampal neural responses were unique, striatal place and movement-correlated neurons were simultaneously recorded with hippocampal neurons. Striatal place and movement cells exhibited a response profile that was similar, but not identical, to that observed for hippocampus after a strategy switch. Thus, retrieval of a different memory led both neural systems to represent a different context. However, hippocampus may play a special (though not exclusive) role in flexible spatial processing since correlated firing amongst cell pairs was highest when rats successfully switched between two spatial tasks. Correlated firing by striatal cell pairs increased following any strategy switch, supporting the view that striatum codes change in reinforcement contingencies. 相似文献

Evidence from lesion, electrophysiological, and neuroimaging studies support the hypothesis that the hippocampus and dorsal striatum process afferent inputs in such a way that each structure regulates expression of different behaviors in learning and memory. The present study sought to determine whether rats explicitly trained to perform one of two different learning strategies, spatial or response, would display disparate immediate early gene activation in hippocampus and striatum. c-Fos and Zif268 immunoreactivity (IR) was measured in both hippocampus and striatum 30 or 90 min following criterial performance on a standard plus-maze task (place learners) or a modified T-maze task (response learners). Place and response learning differentially affected c-Fos-IR in striatum but not hippocampus. Specifically, explicit response learning induced greater c-Fos-IR activation in two subregions of the dorsal striatum. This increased c-Fos-IR was dependent upon the number of trials performed prior to reaching behavioral criterion and accuracy of performance during post-testing probe trials. Quantification of Zif268-IR in both hippocampus and striatum failed to distinguish between place and response learners. The changes in c-Fos-IR occurred 30 min, but not 90 min, post-testing. The synthesis of c-Fos early in testing could reflect the recruitment of key structures in learning. Consequently, animals that were able to learn the response task efficiently displayed greater amounts of c-Fos-IR in dorsal striatum. 相似文献

Behavioral inhibition and behavioral activation levels have been theorized to relate to a broad range of psychopathologies. To date, however, studies have focused on a single diagnosis, and the measures used to assess different psychopathologies have varied greatly. This study assessed how levels of behavioral inhibition and behavioral activation relate to lifetime diagnoses of depression, anxiety, drug abuse and dependence, alcohol abuseand dependence, attention deficit hyperactivity disorder, and conduct disorder. A representative community sample of 1,803 individuals between the ages of 19 and 21 in the Miami area was surveyed with the Composite International Diagnostic Interview and the Behavioral Inhibition and Behavioral Activation Scales (BIS/BAS; C. S. Carver & T. White, 1994). Results supported the role of BIS as a vulnerability factor for depression and anxiety and of BAS Fun Seeking for drug abuse and noncomorbid alcohol diagnoses. Other models were not supported. Goals in understanding BIS and BAS are described, including the need for prospective studies with a broader array of behavioral indices. 相似文献

Thirty women who had prophylactic oophorectomy (PO) and thirty women undergoing ovarian cancer surveillance (OCS) completed a one-time in-depth telephone interview exploring information gathering and decision-making processes. There were close similarities between groups, including age, race, marital status, education, menopausal status, number undergoing genetic testing for BRCA mutations, and number of prophylactic mastectomies. The majority of participants indicated overall satisfaction with their final decision. However, many described the information gathering process as frustrating and anxiety provoking. Participants in both groups expressed a need to process medical information within the context of individual psychosocial needs and personal perceptions and experiences. There were recurrent themes with regard to informational and psychosocial needs and personal perceptions and experiences that impacted decision-making process for these women. The present paper is a companion paper to Swisher et al. (J Repr Med 2001, 46:87–94) with the focus of this paper to illustrate the medical informational processing needs identified by this group of women. 相似文献

ABSTRACTWhile much of the focus on brain injury has centered on athletes and military veterans, victims of domestic violence (DV) comprise an under-represented cohort. Epidemiological studies show that a majority of domestic violence cases have a history of trauma to the head or neck resulting in both TBI and oral maxillofacial damage. However, distinctive oral injuries that are sustained simultaneously with brain trauma as a result of DV have yet to be fully elucidated. If a correlation can be made between specific oral injuries and TBI, then dentition may serve as a reliable biomarker for TBI. Specific dental biomarkers of injury would improve identification, diagnosis, and prognosis of TBI regardless of patient declamation. Dentists have the opportunity and obligation to add significantly to the body of knowledge regarding the frequency, presentation, profile, and characteristics of head and neck injuries of TBI in victims of DV. In so doing, the effort will fill the knowledge gaps and clarify misinformation in the lay, clinical, and scientific communities regarding the impact of TBI in DV events. The dental field can become a leader in branding the procedures, protocols, and clinical practices in the recognition and intervention against TBI in the DV population. 相似文献

Clinicians have long noted overlap in some of the key features of narcissism and bipolar disorder, including excessively high goals and impulsivity. In addition, empirical findings consistently document high levels of comorbidity between the two conditions. To better understand the similarities and differences in psychological qualities associated with mania- and narcissism-related vulnerabilities, we administered to 233 undergraduates a broad range of measures pertaining to goals and affects (both their experience and their dysregulation) and impulsivity. As hypothesized, tendencies toward both narcissism and hypomania related to elevations on measures of affective and goal dysregulation. In addition, hypomania tendencies were related to higher impulsivity, but that association did not appear for narcissistic tendencies. Results highlight key commonalities and differences between those at risk for mania versus narcissism. Future research should examine these relationships in clinically diagnosed samples. 相似文献
