This study aimed to develop a medication literacy scale for parents of children with epilepsy (MLSPCE) and to test the reliability and validity of the scale.
The pilot scale was formulated based on the concept of medication literacy, the knowledge-attitude-practice model, and relevant literature reviews. It was formed through two rounds of expert consultations using the Delphi method. A survey of 657 parents of children with epilepsy, who were admitted to the neurology department or examined in the neuro-electrophysiological outpatient department of Guangzhou Women and Children Medical Center, using the pilot scale was conducted from October 2021 to January 2022 to test the reliability and validity of the scale questionnaire. The content validity of the scale questionnaire was assessed by consulting 20 neurology nursing, neurology clinician, and nursing education experts. Numbers, percentages, -test, correlation analysis, Cronbach's alpha reliability coefficient and factor analysis were used for data analysis.
The MLSPCE included 34 items in four dimensions. Ten factors were drawn from the explorative factor analysis, with a cumulative variance contribution rate of 62.32%. The content validity index of each item on the 34-item scale was between 0.81 and 1.0, and the scale-content validity index/ average was 0.97. The correlation coefficient between each item and its dimension was between 0.399 and 0.760, the correlation coefficients between dimensions were between 0.150 and 0.382, and the correlation coefficients between each dimension and the total scale were between 0.390 and 0.845. Differences for all comparisons were statistically significant (P < 0.05). Cronbach's alpha coefficient for the total scale was 0.864, and the split-half reliability of the total scale was 0.923.
All the statistical procedures performed in the validity and reliability stages of the study showed that MLSPCE is a valid and reliable tool for measuring medication literacy among Chinese parents of children with epilepsy.
本研究旨在开发一种用于癫痫患儿家长的用药素养量表（MLSPCE），并检验该量表的信效度。
初步量表基于用药素养的概念、知信行模型及相关文献综述制定。通过两轮德尔菲法专家咨询形成该量表。于2021年10月至2022年1月，使用初步量表对657名在广州妇女儿童医疗中心神经内科住院或在神经电生理门诊就诊的癫痫患儿家长进行调查，以检验量表问卷的信效度。通过咨询20名神经内科护理、神经内科临床医生及护理教育专家评估量表问卷的内容效度。数据分析采用数值、百分比、t检验、相关分析、Cronbach's α信度系数及因子分析。
MLSPCE包括四个维度的34个条目。探索性因子分析提取出10个因子，累积方差贡献率为62.32%。34个条目量表中各条目的内容效度指数在0.81至1.0之间，量表内容效度指数/均值为0.97。各条目与其维度的相关系数在0.399至0.760之间，维度间的相关系数在0.150至0.382之间，各维度与总量表的相关系数在0.390至0.845之间。所有比较差异均具有统计学意义（P<0.05）。总量表的Cronbach's α系数为0.864，总量表的分半信度为0.923。
本研究在效度和信度阶段所进行的所有统计程序均表明，MLSPCE是一种有效且可靠的工具，可用于测量中国癫痫患儿家长的用药素养。
