背景：本研究目的為(1)發展一個以個人化簡訊提示為基礎(PSMP)的遠距健康照護模式，該模式為修改自個案醫院以醫療為基礎的遠距健康照護模式。(2)發展一個隨機分派試驗，以驗證這兩個照護模式對職場高血壓風險族群健康管理之成效。
方法：研究首先發展一個以醫療為基礎的遠距健康照護模式。其後依據理論與實務設計一套個人化簡訊提示系統與遠距健康照護模式。最後發展一個三臂的研究設計，總樣本個數為441人，追蹤三個月，採雙盲隨機分派實驗。
結果：研究顯示這兩種遠距健康照護模式均能顯著提高受測者高血壓自我效能感。介入模式能提高受測者平日運動天數、改善居家血壓量測次數與職場血壓量測次數。研究介入效果顯著受到高血壓管理自我效能感中介。
結論：以醫療為基礎的遠距健康照護模式及以個人化簡訊為基礎的遠距健康照護模式對職場高血壓風險族群的自我健康管理成效均顯著高於對照組，兩者模式之介入效果則相近無顯著差異。

Background. The research purposes are: (1) to develop a personalized short message prompting based (PSMP) telehealthcare model: The model is modified by the medical care based telehealthcare model developed in the case hospital; and (2) to validate the efficacy of the developed model with a randomized controlled trial in a workplace population with hypertension at risk.
Method. The study first developed a medical care based telehealthcare model in a case hospital. Next, a PSMP protocol was designed and carried out a randomized controlled trial. A totally 441 participants finished the 3 months trial and were randomized assigned with double blinded to the three-arm trial.
Result. The interventions of both telehealthcare models can significantly enhance the belief of self-efficacy comparing to the control condition. The interventions effects include physical activity, blood pressure measurement at home, and blood pressure measurement at workplace. The mediation effect is significantly on blood pressure measurement at home, rather than on blood pressure at workplace.
Conclusion. The medical care based telehealthcare model and the PSMP telehealthcare model were found to be effective in enhancing individual’s psychological states and health-related self management behaviors with regard to hypertension at risk. No significant differences were found in the two telehealthcare models.
