The principles, design considerations, and components of a clinical information system intended to support and enhance the patient care, educational, and research missions of a comprehensive psychiatric institute are presented. Major characteristics of the system are its emphases on efficiency, simplicity, and intensive user involvement throughout the development of the system.  相似文献

This study provides evidence that the effects of perceived pervasive discrimination may be dynamic over time. It was expected that participants who perceived discrimination to be highly pervasive would initially be more likely to engage in inactive coping strategies than those who perceived low pervasiveness; however, those who continued to perceive high pervasiveness over time were expected ultimately to engage in more active strategies than those perceiving low pervasiveness. Using a 28-day diary, women and ethnic minorities described their daily experiences of discrimination and indicated their appraisals of its pervasiveness as well as their coping strategies. Results showed that participants who initially perceived low pervasiveness reported more active coping and religion use as well as less behavioral disengagement than those initially perceiving high pervasiveness. However, this pattern was reversed by the end of the study. Implications for integrating time into the assessment of coping with discrimination are discussed.  相似文献

A scale assessing generalized false self‐perceptions (Perceptions of False Self, POFS) was developed and tested across three studies involving a total of 331 adolescents (11–16 years). In Study 1, interviews were conducted to develop items for the scale. In Study 2, psychometric techniques were used to derive a scale composed of 16 items. Study 2 also assessed the validity of the scale: depressive symptoms were found to increase POFS across 10 weeks, whereas false self‐perceptions had a reciprocal effect on anxiety. In Study 3, the convergent validity of the POFS scale was established. Overall, the evidence suggests that the POFS scale is a reliable and valid measure of generalized false self‐perceptions.  相似文献
