Cluster RCT including 500 Danish publically employed workers (mainly manual workers). Intervention: information-based (2 1-hour talks) based on current knowledge related to e.g. back pain aetiology, the positive link between work and health, the good prognosis in most cases of back pain, but most importantly the information was based on the 'functional-disturbance'-model proposed by the Norwegian Professor Aage Indahl. The information had the purpose of reducing pain-related insecurity about the resistability of the back (no detectable injury).11 clusters were randomized to either intervention or control and the intervention group were offered the two talks. the next 12 months, 12 monthly data-collections were conducted using Short Message Service (SMS) and telephone interview as backup. Outcomes were: physical function, sick leave, work ability, use of healthcare, bothersomeness, restricted activity, frequency of pain medication use, leel of sadness/depression and back beliefs. Items from validated scales were used.<br>Results: will be updated when the paper is published (accepted by PLOS ONE February 2017)

本研究为一项集群随机对照试验（Cluster Randomized Controlled Trial，RCT），纳入500名丹麦公职人员（以体力劳动者为主）。
干预措施为信息宣教类干预方案：包含2次时长1小时的讲座，内容涵盖背痛病因学、工作与健康的正向关联、多数背痛病例预后良好等相关知识，核心依据为挪威教授奥拉夫·因达尔（Aage Indahl）提出的“功能障碍模型”。该宣教旨在减轻受试者因背部抗损伤能力（无可检测到的损伤）产生的疼痛相关不安感。本研究共设置11个集群，按随机分组原则分为干预组与对照组，干预组可参与上述2次讲座。
在随后的12个月内，每月开展1次数据采集，总计12次，数据收集采用短消息服务（Short Message Service，SMS），以电话访谈作为备用收集方式。本次研究的结局指标包括：躯体功能、病假情况、工作能力、医疗服务使用情况、不适感程度、活动受限情况、止痛药物使用频率、悲伤/抑郁水平以及背部健康信念。研究采用经过信效度验证的量表条目完成数据收集。
研究结果将在论文发表时更新（该论文于2017年2月被《PLOS ONE》期刊录用）。
