基于移动电话的评估可能是一种具有成本效益和临床有效的实时监测精神病症状的方法。有几种软件选择，包括使用本地智能手机应用程序和短信（短消息服务，SMS）。对于这两种方法在监测严重精神疾病患者症状方面的优势和局限性，人们知之甚少。本研究的目的是比较非情感性精神病患者同一诊断评估的两种不同交付方式——采用图形触摸用户界面的原生智能手机应用程序与仅使用短信文本的应用程序。本研究的总体假设是，通过定量评估后反馈问卷得分、完成的数据点数量和完成评估所需的时间来衡量，患有严重精神疾病的患者会发现两种分娩方式都是可行的，并且可以接受使用。据预测，原生智能手机应用程序将(1)产生更多的数据点，(2)花费更少的时间，(3)比基于文本的系统更能得到患者参与者用户的积极评价。采用随机重复测量交叉设计。目前正在接受诊断与统计手册（第四版）治疗的精神分裂症或相关疾病的参与者（n=24）被随机分配到使用原生智能手机应用程序或SMS纯文本实施完成6天的评估（每天四组问题）。然后有1周的休息时间，然后再用另一种分娩方式完成6天。在每个采样期结束时进行定量反馈问卷调查。与仅使用短信文本的应用程序相比，使用原生智能手机应用程序完成数据点的比例更大（β = - 0.25， SE= 0.11， P= 0.02），完成时间也明显更短（β = 0.78， SE= 0.09， P< 0.001）。尽管参与者对两种递送方式的定量反馈没有显著差异，但大多数参与者报告更喜欢本地智能手机应用程序（67%,n=16），并发现它更容易使用（71%,n=16）。33%的参与者报告说，他们愿意完成5周或更长时间的手机评估。原生智能手机应用程序和短信都是对精神分裂症患者进行实时评估的有价值的方法。然而，更精简的图形用户界面可能会带来更好的遵从性和更短的输入时间。需要进一步的研究来测试这项技术在临床服务中的有效性，以评估在更长的时间内以及在患者自己的手机上提供时的有效性。
Mobile phone–based assessment may represent a cost-effective and clinically effective method of monitoring psychotic symptoms in real-time. There are several software options, including the use of native smartphone applications and text messages (short message service, SMS). Little is known about the strengths and limitations of these two approaches in monitoring symptoms in individuals with serious mental illness. The objective of this study was to compare two different delivery modalities of the same diagnostic assessment for individuals with non-affective psychosis—a native smartphone application employing a graphical, touch user interface against an SMS text-only implementation. The overall hypothesis of the study was that patient participants with sewrious mental illness would find both delivery modalities feasible and acceptable to use, measured by the quantitative post-assessment feedback questionnaire scores, the number of data points completed, and the time taken to complete the assessment. It was also predicted that a native smartphone application would (1) yield a greater number of data points, (2) take less time, and (3) be more positively appraised by patient participant users than the text-based system. A randomized repeated measures crossover design was employed. Participants with currently treated Diagnostic and Statistical Manual (Fourth Edition) schizophrenia or related disorders (n=24) were randomly allocated to completing 6 days of assessment (four sets of questions per day) with a native smartphone application or the SMS text-only implementation. There was then a 1-week break before completing a further 6 days with the alternative delivery modality. Quantitative feedback questionnaires were administered at the end of each period of sampling. A greater proportion of data points were completed with the native smartphone application in comparison to the SMS text-only implementation (β = -.25, SE=.11, P=.02), which also took significantly less time to complete (β =.78, SE= .09, P<.001). Although there were no significant differences in participants’ quantitative feedback for the two delivery modalities, most participants reported preferring the native smartphone application (67%; n=16) and found it easier to use (71%; n=16). 33% of participants reported that they would be willing to complete mobile phone assessment for 5 weeks or longer. Native smartphone applications and SMS text are both valuable methods of delivering real-time assessment in individuals with schizophrenia. However, a more streamlined graphical user interface may lead to better compliance and shorter entry times. Further research is needed to test the efficacy of this technology within clinical services, to assess validity over longer periods of time and when delivered on patients’ own phones.
