Smartphone overuse is prevalent among healthcare professionals. There is no standard scale that can measure the impact of smartphone usage on healthcare professionals. This study aimed to develop and validate a tool, the Smartphone Impact Scale (SIS), that can effectively measure the use of smartphone among healthcare professionals.
We developed a generic instrument to study the impact of smartphone usage among healthcare professionals. A total of 1436 healthcare professionals from various regions of KSA participated in this study through an online questionnaire-based survey. The psychometric properties of the SIS were developed using content validity index (CVI), factor analysis, internal consistency, and test-retest reliability analysis.
A 23-item scale was selected for reliability and validity analysis. The average CVI was found to be 0.824. The internal consistency with Cronbach's alpha value was 0.91, and test-retest reliability was 0.85. The Cronbach's alpha values for Factors 1 and 2 were 0.875 and 0.803, respectively. The confirmatory factor analysis indices were as follows: root mean square of approximation = 0.0710, comparative fit index = 0.861, Tucker-Lewis index = 0.845, and the coefficient of determination = 0.969. The correlation between two factors was 0.66. After factor analysis, we developed a final questionnaire with 23 items.
Our SIS showed a three-factor structure and appropriate psychometric characteristics. Due to its adequate reliability and validity, SIS can be conveniently used to evaluate the impact of smartphone usage on healthcare professionals.
智能手机过度使用在医疗保健专业人员中很普遍。目前尚无能够衡量智能手机使用对医疗保健专业人员影响的标准量表。本研究旨在开发并验证一种工具——智能手机影响量表（SIS），该量表能够有效测量医疗保健专业人员对智能手机的使用情况。
我们开发了一种通用工具来研究智能手机使用对医疗保健专业人员的影响。来自沙特阿拉伯王国不同地区的1436名医疗保健专业人员通过基于在线问卷的调查参与了本研究。使用内容效度指数（CVI）、因子分析、内部一致性和重测信度分析来确定SIS的心理测量特性。
选择了一个包含23个条目的量表进行信效度分析。发现平均CVI为0.824。Cronbach's α值的内部一致性为0.91，重测信度为0.85。因子1和因子2的Cronbach's α值分别为0.875和0.803。验证性因子分析指标如下：近似均方根=0.0710，比较拟合指数=0.861，塔克-刘易斯指数=0.845，决定系数=0.969。两个因子之间的相关性为0.66。经过因子分析，我们编制了一份最终包含23个条目的问卷。
我们的SIS显示出三因素结构和适当的心理测量特征。由于其具有足够的信效度，SIS可方便地用于评估智能手机使用对医疗保健专业人员的影响。
