Till now no validated instrument exists to measure the readiness and attitude of diabetic patients towards the use of telemonitoring. The purpose of the described study was to develop a Telemonitoring Attitude and Readiness Questionnaire and to check its validity and reliability.
After performing in-depth interviews in two separate sessions, the Telemonitoring Attitude and Readiness Questionnaire was completed by a convenience sample of 138 patients with type 1 and type 2 diabetes to determine internal consistency. Test-retest reliability was further evaluated with a subsample of 21 patients.
Analysis supports the validity and reliability of the 13-item Telemonitoring Health Effect and Readiness Questionnaire (THERQ) with three subscales: Communication with peers or during holidays with a professional (Cronbach's alpha=0.84), telemonitoring health effect (Cronbach's alpha=0.87), and communication with a professional from home (Cronbach's alpha=0.88). Test-retest reliability is satisfactory (intraclass correlation coefficients between 0.58 and 0.92).
The results of this study provide preliminary evidence that the Telemonitoring Health Effect and Readiness Questionnaire is a valid and reliable instrument to measure the readiness and subjective feelings of health effect towards the use of telemonitoring. The THERQ could be used before the implementation of telemonitoring to check if diabetic patients are interested in the use of it but it could also be used in (randomized) controlled trials as the questions are put in such a way that also patients not (yet) using telemonitoring can answer the questions.
到目前为止，还没有经过验证的工具可以衡量糖尿病患者使用远程监测的准备情况和态度。本研究的目的是开发一种远程监测态度和准备情况问卷，并检查其有效性和可靠性。
在两次单独的访谈之后，138 名 1 型和 2 型糖尿病患者的便利性样本完成了远程监测态度和准备情况问卷，以确定内部一致性。进一步用 21 名患者的亚样本评估了重测信度。
分析支持了 13 项远程监测健康效果和准备情况问卷（THERQ）的有效性和可靠性，该问卷有三个分量表：与同行或专业人士在假期期间的沟通（Cronbach's alpha=0.84）、远程监测健康效果（Cronbach's alpha=0.87）和在家与专业人士沟通（Cronbach's alpha=0.88）。重测信度令人满意（组内相关系数在 0.58 到 0.92 之间）。
本研究结果初步表明，远程监测健康效果和准备情况问卷是一种有效的工具，可以衡量糖尿病患者对使用远程监测的准备情况和主观健康效果感受。THERQ 可以在实施远程监测之前使用，以检查患者是否对其使用感兴趣，但它也可以在（随机）对照试验中使用，因为问题的提出方式使得那些尚未使用远程监测的患者也可以回答这些问题。
