Mobile technology has been increasingly adopted in promotion of mental health among older people. This study assessed the feasibility of a mobile mental wellness training application for individual use and for group work from the perspectives of older adults and social care professionals. The older individuals recruited for the study were participants in a Circle of Friends group and family caregivers' peer support group offered by the communal senior services. The qualitative and quantitative results of interviews, questionnaires, observation, and application usage were reported. Seven older adults started using the application independently at home in parallel with the group activity. This study revealed new information regarding the barriers to the older adults' full adoption of such mobile technologies. The results indicated that there may be potential in the incorporation of mobile technologies in promotion of mental health of older people at group settings. 相似文献

In 2011, a small pilot bike share program was established in the town core of Kailua, Hawai‘i, with funding from the Hawai‘i State Department of Health. The Kailua system consisted of two stations with 12 bicycles, and the goal was to secure additional funding to expand the station network in the future. Community feedback consistently indicated support for the bike share program. However, system metrics showed low levels of usage, averaging 41.5 rides per month (2011–2014). From observational data, users were primarily tourists. With minimal local staff, the bike share program had limited resources for promotion and education, which may have hindered potential use by local residents. Management of station operations and bike maintenance were additional, ongoing barriers to success. Despite the challenges, the pilot bike share program was valuable in several ways. It introduced the bike share concept to Hawai‘i, thereby helping to build awareness and connect an initial network of stakeholders. Furthermore, the pilot bike share program informed the development of a larger bike share program for urban Honolulu. As limited information exists in the literature about the experiences of smaller bike share programs and their unique considerations, this article shares lessons learned for other communities interested in starting similar bike share programs. 相似文献

Female problem drinkers are less likely than men to be identified in the primary care setting. The authors studied 24 adult women attending a general, internal medicine clinic to assess the efficiency of self reports of alcohol consumption when compared with physician identification and other measures and the impact of a brief intervention on alcohol consumption. Despite the high rate of lifetime (79%) and current (67%) alcohol diagnoses, no patient was in alcohol treatment. Physician identification of alcohol problems was least sensitive but most specific, when compared with other measures. Brief intervention, as offered in this study, did not appear to modify alcohol consumption. 相似文献
