Adherence to medications for chronic pediatric diseases decreases overtime. This randomized controlled trial evaluated a clinic-based, nurse-administered educational and behavioral intervention to prevent the anticipated drop in adherence to nonsteroidal medications among newly diagnosed patients with juvenile rheumatoid arthritis. Thirty-four participants completed the study (mean age = 8.44 years, SD = 3.96), including 19 in the experimental group and 15 in the standard-treatment (education) control group. There were significant group and Group x Time effects for adherence (assessed with an electronic monitor over a 13-month period) favoring the experimental group. In contrast, the groups did not differ significantly in disease activity or functional limitations. Factors that may have prevented detection of differences in these health parameters are dicussed.  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

Abstract

As more organizations implement multinational strategies, sales managers leading sales forces encounter complex cultural challenges that affect relationships, processes, and outcomes. We undertake a qualitative study with the objective of understanding the sales manager–salesperson relationship when the sales manager is leading sales representatives located in other cultures. Because of the significant size and growth of Asian countries, we focus our study on the Asia-Pacific Rim region. In-depth interviews conducted with 21 sales managers working for a large multinational technology firm in our focal region provide the data for our analysis. Using a grounded theory approach, we identify five key themes: building and sustaining cross-cultural relationships, cross-cultural communication effectiveness, acquisition and maintenance of trust across cultures, language, and decision-making. From our findings, research propositions are offered and implications for researchers and practitioners are discussed.  相似文献
