摘要

简介:本研究的目的是利用偏最小二乘(PLS)建模技术调查移动健康在大流行管理中的不同作用。由于现有关于理论化的文献有限,并且缺乏预测移动健康在大流行管理中的作用的默认模型,因此使用该方法进行探索性建模。材料和方法:使用smart-PLS软件进行PLS模型的以下步骤:估计权重比,考虑权重比作为输入,估计参数,模型拟合和检验假设。此外,回归方程中的因子得分用于估计结构参数。测量和可靠性评价模型拟合优度采用PLS算法、Cronbach’s alpha和复合信度。此外,采用R2指标评价模型的充分性。对显著系数采用自举法。通过标准化均方根残差(SRMR)标准检验模型的拟合优度。结果:确定了测量模型的拟合优度,其alpha值为:诊断结构=0.786,随访=0.772,治疗=0.796,医疗服务提供者=0.704,教育=0.839,各综合信度指标均大于0.7,各领域结构模型指标R2均大于0.6,整体模型SRMR拟合优度为-0.007,各路径标准化系数均大于1.96,模型提出的5个假设均得到证实。此外,提出的关于移动医疗在大流行时期在诊断、治疗和后续行动、教育和保健提供者方面发挥积极和重要作用的模型获得批准。结论:本研究结果可作为建立移动健康在大流行管理中作用相关模型的理论基础。此外,卫生政策制定者和从业人员可以利用这些结果来管理当前和之后的冠状动脉疾病,并促进基于各种移动健康应用程序的服务。

An Assessment of m-Health Effect on Covid-19 Management Using PLS Modeling Approach
Introduction: The aim of the present study was to investigate the different roles of m-Health in pandemic management using the Partial Least Square (PLS) modeling technique. Owing to the limited existing literature regarding theorizing and the lack of the default model in predicting the role of m-Health in pandemic management, this method was used for exploratory modeling.Material and Methods: The PLS model was performed with smart-PLS software for the following steps: estimating weight ratios, considering weight ratios as input, estimating parameters, model-fitting and testing hypotheses. In addition, Factor scores in regression equations were used to estimate structural parameters. PLS algorithm, Cronbach's alpha, and Composite Reliability were used for the measurement and reliability evaluation model Goodness-of-fit. In addition, the R2 index was used to evaluate the model adequacy. Bootstrapping was used for significant coefficients. The Goodness-of-fit of the model was examined via the Standardized Root Mean Square Residual (SRMR) criterion.Results: It is determined the measurement models goodness-of-fit which the alpha values were as follows: diagnosis construct=0.786, follow-up=0.772, treatment=0.796, health care providers=0.704 and education=0.839 with more than 0.7 for all measures for Composite Reliability, the structural model measures such as R2 were higher than 0.6 for all areas and the overall model goodness-of-fit was -0.007 for SRMR, the five hypotheses developed in the model were confirmed according standardized coefficients more than 1.96 for all paths. Furthermore, the proposed model concerning the positive and significant role of m-Health in diagnosis, treatment and follow-up, education and health providers during the pandemic era was approved.Conclusion: The results of the present study can be used as a theoretical basis in developing models related to the role of m-Health in pandemic management. Also, health policymakers and practitioners could use the results to manage current and post-coronary conditions and to promote services based on various m-Health apps.
