新型冠状病毒肺炎疫情下信息过载严重程度量表的编制

Development of information overload severity scale in the situation of coronavirusdisease 2019 epidemic

目的在新型冠状病毒肺炎疫情下编制信息过载严重程度量表,并对其进行信效度评价。方法于2020年2月-3月按照文献分析、半结构式访谈、专家咨询的流程形成初始量表,然后进行线上量表实测,针对量表实测结果进行量表条目筛选,并使用探索性因子分析及Cronbachα评价其信效度。结果初始量表共8个条目,通过离散程度、与总得分相关系数及因子载荷相关指标进行量表条目筛选,最终形成7个条目的量表。量表的因子分析结果显示该量表能提取1个成分,信度分析显示该量表总的Cronbachα系数为0.863。结论信息过载严重程度量表具有较好的信效度,可以为新型冠状病毒肺炎疫情后及其他重大公共事件之后进行相关研究提供有力的支持。

Objective To compile the information overload severity scale in the situation of coronavirus disease 2019 epidemic,and evaluate the reliability and validity.Methods From February to March 2020,according to the procedures of literature analysis,semi-structured interview,and expert consultation,an initial scale was formed;and then the online scale was measured,and the scale items were screened based on the measured results of the scale.The reliability was evaluated by Cronbach’sαcoefficient,and the validity was tested by exploratory factor analysis.Results There were 8 items in the initial scale.The scale items were screened based on the degree of dispersion,the correlation coefficient with the total score,and the factor-load-related indicators,and finally a 7-item scale was formed.The factor analysis results of the scale showed that one component could be extracted from the scale,and the reliability analysis showed that the total Cronbach’sαcoefficient of the scale was 0.863.Conclusion The information overload severity scale has good reliability and validity,which can provide strong support for related research after the outbreak of coronavirus disease 2019 and other major public events.
