本研究目的主要是偶健康信念模式分析醫院護理人員之下背痛預防行為及其相關因素，以提供日後進行教育介入參考。本研究採橫斷式調查研究設計，經由焦點團體法篩選出重、顯著之健康信念，作為問卷發展之依據，以臺北市立八家醫院之全體護理人員為對象，其後於91年3~4月間以自填式問卷方式進行施測，得有效樣本2034名，回收率90.5%。研究之重要結果如下： 一、護理人員罹患下背痛比率為61.6%，比例偏高。其年盛行率、月盛行率、週盛行率分別為42.4%、19.8%、14.3%。 二、不同社會人口學變項會影響護理人員之健康信念、行動線索、下背痛預防行為及傾向。 三、在健康信念方面，發「下背痛動障礙認知」、「規律運動」與「行動線索」對護理人員下背痛預防行為的解釋力最大；「下背痛行動障礙認知」對預防下背痛行為傾向的解釋力最大。 四、健康信念模式用來解釋下背痛預防行為，達到30.1%變異量的解釋力，對預防下背痛行為傾向之解釋力則有26.4%的變異量。
