Social Validity in Spain of the Mantente REAL Prevention Program for Early Adolescents : Social Validity of Mantente Real in Spain.

Studies focusing on the relevance or impact of a program, not just on its efficacy or effectiveness, can make important contributions to prevention science. This article documents the social validity (i.e., a construct encompassing feasibility, acceptability, and utility) of a universal substance use prevention program for early adolescents in Spain. The Mantente REAL (keepin'it REAL) program was culturally adapted to the Spanish context, implemented, and evaluated in six public middle schools in two regions of Spain. Participating teachers (N = 15), students (N = 354), and research team members (N = 6) reported on the feasibility, acceptability, and utility of the program implemented with first grade secondary school students. Qualitative and quantitative data about the program, its curriculum, and the implementation process were collected through teachers' focus groups, students' surveys, and observation forms completed by members of the research team. Mantente REAL was perceived to be a prevention program that was feasible for implementation in Spanish middle schools, although some logistics related to school structural constraints should be addressed in future implementations. The topics and activities in the curriculum were highly accepted by teachers and students, and they reported that the program was useful in teaching resistance strategies to cope with substance use and other risky situations. The findings support the social validity of the culturally adapted Mantente REAL program for early adolescents in Spain, and highlight how feedback from stakeholders involved in the implementation can improve the dissemination of effective prevention approaches.

Higgs physics at the CLIC electron-positron linear collider.

The Compact Linear Collider (CLIC) is an option for a future [Formula: see text] collider operating at centre-of-mass energies up to [Formula: see text], providing sensitivity to a wide range of new physics phenomena and precision physics measurements at the energy frontier. This paper is the first comprehensive presentation of the Higgs physics reach of CLIC operating at three energy stages: [Formula: see text], 1.4 and [Formula: see text]. The initial stage of operation allows the study of Higgs boson production in Higgsstrahlung ([Formula: see text]) and [Formula: see text]-fusion ([Formula: see text]), resulting in precise measurements of the production cross sections, the Higgs total decay width [Formula: see text], and model-independent determinations of the Higgs couplings. Operation at [Formula: see text] provides high-statistics samples of Higgs bosons produced through [Formula: see text]-fusion, enabling tight constraints on the Higgs boson couplings. Studies of the rarer processes [Formula: see text] and [Formula: see text] allow measurements of the top Yukawa coupling and the Higgs boson self-coupling. This paper presents detailed studies of the precision achievable with Higgs measurements at CLIC and describes the interpretation of these measurements in a global fit.

The impact of managed care on physicians.

This article investigates physicians' perceptions of how managed care has affected them, using data from a 1995 survey of Arizona physicians. Respondents report that participation in managed care has had significant and largely unpleasant effects on numerous aspects of medical practice: physician-patient relationships, clinical decision making, work conditions and settings, and overall satisfaction.

Physician satisfaction in a changing health care environment: the impact of challenges to professional autonomy, authority, and dominance.

For some time, sociologists have debated whether physicians still retain dominance in the health care world, public faith in their moral and scientific authority, and the autonomy to set work conditions and make clinical decisions. Using ideas derived from this debate, we analyze the impact of changes in the health care environment on physician satisfaction. Our data come from a mailed survey of 510 Arizona physicians. Our results show that background physician attributes did not predict satisfaction, nor did most organizational attributes. However, participation in IPAs (Individual Practice Associations) predicted higher satisfaction, while payment according to a third party payer's fee-for-service schedule predicted lower satisfaction. In addition, physicians were more likely to be satisfied if they wrote the orders that non-physicians had to follow, were paid what they wanted, did not need to subordinate their clinical judgment to that of non-physicians, and believed that their patients had confidence in physicians. Our conclusions discuss both theoretical and policy implications of our findings.
