以技术为基础的改变生活方式的辅助手段在慢性病患者中越来越普遍。重要的“数字鸿沟”仍然存在,以及对隐私、数据安全和缺乏动力的担忧。研究人员需要一种方法来描述参与者使用卫生技术的准备程度。为了满足这一需求,我们创建了一个工具来衡量患有慢性病的成年患者是否愿意参与卫生技术。最初的焦点小组,以确定领域,其次是项目的发展和完善,探索性因素分析,以确定最终的项目和因素结构。开发样本包括来自6个家庭医学诊所的200名慢性病患者。从98个潜在项目中,53个最佳候选项目进行了探索性因素分析。3个月时测试/重测可靠性的Pearson相关性。最终的工具有28个项目,分为8个因素与相关的克朗巴赫的α:1)健康信息需求(0.84),2)电脑/互联网经验(0.87),3)计算机焦虑(0.82),4)优选的相互作用模式(0.73),5)与医生的关系(0.65),6)手机专业知识(0.75),7)互联网隐私(0.71),和8)没有消息就是好消息(0.57)。8个分量表的重测信度在0.60 ~ 0.85之间。患者参与健康互联网技术(PRE-HIT)工具具有良好的心理测量特性,将有助于研究人员调查基于技术的健康干预措施。未来的工作将检查预测的有效性。
Technology-based aids for lifestyle change are becoming more prevalent for chronic conditions. Important “digital divides” remain, as well as concerns about privacy, data security, and lack of motivation. Researchers need a way to characterize participants’ readiness to use health technologies. To address this need, we created an instrument to measure patient readiness to engage with health technologies among adult patients with chronic conditions. Initial focus groups to determine domains, followed by item development and refinement, and exploratory factor analysis to determine final items and factor structure. The development sample included 200 patients with chronic conditions from 6 family medicine clinics. From 98 potential items, 53 best candidate items were examined using exploratory factor analysis. Pearson’s Correlation for Test/Retest reliability at 3 months. The final instrument had 28 items that sorted into 8 factors with associated Cronbach’s alpha: 1) Health Information Need (0.84), 2) Computer/Internet Experience (0.87), 3) Computer Anxiety (0.82), 4) Preferred Mode of Interaction (0.73), 5) Relationship with Doctor (0.65), 6) Cell Phone Expertise (0.75), 7) Internet Privacy (0.71), and 8) No News is Good News (0.57). Test-retest reliability for the 8 subscales ranged from (0.60 to 0.85). The Patient Readiness to Engage in Health Internet Technology (PRE-HIT) instrument has good psychometric properties and will be an aid to researchers investigating technology-based health interventions. Future work will examine predictive validity.
