本研究的目的是开发一个基于社会认知理论（SCT）的老年人结构化髋部骨折预防网站（TSW），并对其有效性进行初步评估。TSW由学习模块和主持讨论板组成。从两个网站和报纸广告招募的245名老年人被随机分为TSW和传统网站（CW）组。结局包括（1）知识（髋部骨折和骨质疏松症），（2）自我效能和结局预期，以及（3）钙摄入量和运动，并在基线、治疗结束（[EOT]，2周）和随访（3个月）时进行评估。两组在大多数结果上都有显著改善。对于钙摄入量，只有TSW组表现出改善。组和时间相互作用均不显著。然而，TSW组对干预更满意。讨论板的使用与结果收益显著相关。尽管存在一些局限性，但研究结果显示了基于网络的老年人健康干预措施的初步有效性，以及TSW作为在线健康行为改变干预措施的可持续网络结构的使用。
The purposes of this study were to develop a Social Cognitive Theory (SCT)-based, Structured Hip Fracture Prevention Website (TSW) for older adults and conduct a preliminary evaluation of its effectiveness. The TSW is comprised of learning modules and a moderated discussion board. A total of 245 older adults recruited from two websites and a newspaper advertisement were randomized into the TSW and the Conventional Websites (CW) groups. Outcomes included (1) knowledge (hip fractures and osteoporosis), (2) self-efficacy and outcome expectations, and (3) calcium intake and exercise, and were assessed at baseline, end-of-treatment ([EOT], 2 weeks), and follow-up (3 months). Both groups showed significant improvement in most outcomes. For calcium intake, only the TSW group showed improvement. None of the group and time interactions were significant. The TSW group, however, was more satisfied with the intervention. The discussion board usage was significantly correlated with outcome gains. Despite several limitations, the findings showed some preliminary effectiveness of web-based health interventions for older adults and the use of a TSW as a sustainable web structure for online health behavior change interventions.
