Hip fracture, a significant public health problem among older adults, can be prevented using multimodal approaches (e.g., bone-strengthening measures, fall prevention). Many older adults, however, are unaware of this information. With the rapid growth of older adult online users who have a specific interest in health, the Web can serve as a valuable medium to disseminate this information.
The purpose of this study was to explore the impact of the social cognitive theory-based structured hip fracture prevention Web site (TSW) on health behaviors through analysis of discussion board postings and to assess participants' experiences with the discussion board.
In an online, randomized controlled study, the effects of a social cognitive TSW, including learning modules and a moderated discussion board, were tested on older adults' health behavior-related outcomes.This was an exploratory qualitative study. The TSW group participants used the learning modules and the discussion board for 2 weeks. Their experiences with the discussion board were explored using an open-ended question. Discussion board postings and qualitative answers were analyzed using content analysis.
Ninety older adults actively participated in the discussion board. Analysis of 316 postings revealed eight themes. Participants shared their current health behaviors and discussed specific health problems and concerns. Many recognized opportunities for improvement and identified motivators to improve health behaviors. They also offered supportive comments to others and shared helpful and practical information. More than half of the participants (n = 65, 74.4%) reported that the discussion board enhanced their learning experiences.
The themes developed from the postings showed that moderated discussion boards can be used effectively to change older adults' health behavior. Further research is needed to explore the long-term impact of using this component in online health behavior change interventions.
髋部骨折是老年人中一个重大的公共卫生问题，可通过多模式方法（如强化骨骼措施、预防跌倒）加以预防。然而，许多老年人并不知晓这一信息。随着对健康有着特定兴趣的老年在线用户迅速增加，网络可成为传播此类信息的宝贵媒介。
本研究旨在通过分析讨论板帖子来探讨基于社会认知理论的结构化髋部骨折预防网站（TSW）对健康行为的影响，并评估参与者在讨论板上的体验。
在一项在线随机对照研究中，对一个包含学习模块和有主持人的讨论板的社会认知TSW对老年人健康行为相关结果的影响进行了测试。这是一项探索性定性研究。TSW组参与者使用学习模块和讨论板两周。通过一个开放式问题探索他们在讨论板上的体验。使用内容分析法对讨论板帖子和定性回答进行分析。
90名老年人积极参与了讨论板。对316条帖子的分析揭示了八个主题。参与者分享了他们当前的健康行为，并讨论了具体的健康问题和担忧。许多人认识到改进的机会，并确定了改善健康行为的动机。他们还向他人提供支持性评论，并分享有用和实用的信息。超过一半的参与者（n = 65，74.4%）报告称讨论板增强了他们的学习体验。
从帖子中提炼出的主题表明，有主持人的讨论板可有效用于改变老年人的健康行为。需要进一步研究来探索在在线健康行为改变干预中使用这一组成部分的长期影响。
