The growing use of digital health communication channels has produced dramatic changes, providing broad access to information for making health decisions and addressing users' emotional needs. Digital health communication channels combine mass and interpersonal communication in different ways. Type 1 convergence occurs sequentially: Individuals obtain health information online that they discuss interpersonally with health providers. Type 2 convergence involves discussions occurring via online health information systems. The effectiveness of these systems depends upon seven communication design and implementation strategies. Emerging interactive health information systems provide customized responses tailored to individuals' specific needs and situations. All these forms of media convergence can improve health education, health promotion, and health behavior change.  相似文献

Jerry Fodor has argued that the multiple realizability argument, as discussed in his original “Special Sciences” article, “refutes psychophysical reductionism once and for all.” I argue that his argument in “Special Sciences” does no such thing. Furthermore, if one endorses the physicalism that most supporters of the “Special Sciences” view endorse, special science laws must be reducible, in principle. The compatibility of MR with reduction, however, need not threaten the autonomy of the special sciences.  相似文献

ABSTRACT

Depression is a serious public health problem in community settings and primary care. The Patient Health Questionnaire-2 (PHQ-2) is a brief screen for depression. The PHQ-2 has not had its validity examined in academic settings in Iran. A cross-sectional study was conducted to investigate the reliability, validity, and factorial structure of the PHQ-2 in a convenience sample of 157 Iranian volunteer college students selected from the Iran University of Medical Sciences. Participants completed the PHQ-2, and the Loneliness Scale (LS). The mean score of the PHQ-2 was 2.26 (SD?=?1.64). The Cronbach's α coefficient was .74, indicating high internal consistency. The PHQ-2 correlated .68 with the LS, demonstrating good construct validity. The results of the factor analysis of the PHQ-2 identified one factor labeled: General depression (79.87% of the variance). The PHQ-2 has a unidimensional structure, acceptable validity and reliability, and it can be used in the non-clinical settings in Iran.  相似文献

Abstract

The COVID-19 pandemic is a global contagion of unprecedented proportions and health, economic, and social consequences. As with many health problems, its impact is uneven. This article argues the COVID-19 pandemic is a global health injustice due to moral failures of national governments and international organizations to prepare for, prevent and control it. Global and national health communities had a moral obligation to act in accordance with the current state of knowledge of pandemic preparedness. This obligation—a positive duty to develop and implement systems to reduce threats to and safeguard individuals’ and, communities’ abilities to flourish—stems from theories of global health justice and governance. The COVID-19 pandemic revealed and amplified the fragility and deficiencies in our global and domestic health institutions and systems. Moving forward, positive public health ethics is needed to set ethical standards for building and operating robust public health systems for resilient individuals and communities.  相似文献
