The psychometric properties of the Beck Depression Inventory-II (BDI-II) are well established with primarily Caucasian samples. However, little is known about its reliability and validity with minority groups. This study evaluated the psychometric properties of the BDI-II in a sample of low-income African American medical outpatients (N=220). Reliability was demonstrated with high internal consistency (.90) and good item-total intercorrelations. Criterion-related validity was demonstrated. A confirmatory factor analysis supported a hierarchical factor structure in which the BDI-II reflected 2 first-order factors (Cognitive and Somatic) that in turn reflected a second-order factor (Depression). These results are consistent with previous findings and thus support the use of the BDI-II in assessing depressive symptoms for African American patients in a medical setting.  相似文献

The present study explored prospective links between trait mindfulness and compassion on subsequent coping and compliance with Centers for Disease Control (CDC) guidelines and indirect effects via well-being and internalized distress during the COVID-19 pandemic. The study included N = 736 US college students who participated in a three-wave longitudinal study across a single academic year. The first two assessment waves took place in 2018 and 2019, respectively, while the third wave took place in May 2020 during the COVID-19 pandemic. Participants completed self-report measures of trait mindfulness, compassion, well-being, internalized distress, coping, and compliance with CDC health guidelines. Results of a series of autoregressive, cross-lagged panel models revealed that trait mindfulness was associated with better coping via indirect effects of greater well-being and lower internalized distress. Greater compassion was linked with greater adherence to CDC guidelines. Findings suggest that trait mindfulness and compassion may play a role in college students' coping and compliance during the pandemic.  相似文献

Data from the evaluation of the DfEE-funded Guidance and Learner Autonomy (GALA) project (1993-96) raise issues about the nature of guidance at the point of learners' induction to courses of higher education. Three institutions of higher education piloted peer tutoring/ guiding arrangements as part of the GALA project: their experiences are analysed The emerging story reported is complex and powerful, and suggests that students have an enhanced role to play in a renegotiated tutor-student relationship. The use of the darkness metaphor aims to convey something of the transition which students experience in moving from the obscurity of their early days at university, towards a more enlightened (and arguably more empowered) position within their institution.  相似文献

Recently there has been interest in an unusual neuropsychological disorder in which the patient copies a complex drawing in a position which is grossly rotated relative to the original. This disorder is of interest partly because of its relationship to current theories of the process of object recognition, but the range of performances typically seen, as well as its anatomical correlates, remain obscure. We report 16 cases who produced grossly rotated drawings of the Rey and Taylor Complex Figures. These patients were drawn from an unselected series of 240 cases, with a wide variety of lesion types and sites. The performances of the 16 patients displayed striking similarities. We describe the formal features of these drawings and plot their anatomical correlates.  相似文献

Young infants have an impressive knowledge of material objects. They appreciate that distinct objects cannot occupy the same space at the same time, are internally cohesive units that maintain their boundaries, and exist continuously in space and time. We report a surprising limit to this body of understanding: Although 8-month-olds responded to the "magical" disappearance of an object as an unexpected event, they did not so respond to a magical appearance. These results suggest that infants' understanding of objects differs from adult cognition in important respects. We discuss four possible ways in which this finding can be reconciled with evidence that infants appreciate the spatiotemporal continuity of objects.  相似文献
