This study aims to develop and validate the Family Management Scale for Children with Asthma (FMSCA) in China context. Based on the Family Management Style Framework (FMSF) model, an original 89 items were generated from literature review and interviews with 15 caregivers of children with asthma. The preliminary scale was refined to 82 items through two rounds of experts' evaluation and a pilot study, then administered to 329 caregivers of children with asthma for testing between April and July 2013. Item analysis and exploratory factor analysis were performed to screen the items, reliability and validity analysis were tested using psychometric techniques (internal consistency, split-half reliability, test-retest reliability, content validity, and construct validity). Confirmatory factor analysis was adopted to further evaluate the construct validity of the scale in an additional 600 children with asthma and their parents from August 2014 to December 2015. Results: A final 57-item FMSCA from 8 subscales (children identity, view of condition, management mindset, parental mutuality, parenting philosophy, management approach, family focus, and future expectation) were generated. The excellent internal consistency (Cronbach's α = 0.918), very good split-half reliability ( = 0.802, < 0.01) and test-retest reliability ( = 0.857, < 0.01) indicate a satisfactory reliability of the FMSCA. The Item Content Validity Index (I-CVI) of the scale ranged 0.8 3 ～1.00, Scale Content Validity Index (S-CVI) was 0.807, indicating a good content validity. Construct validity was established by accepted correlation coefficient of item-to-subscale ( range = 0.513-0.865, < 0.01), intersubscale ( range = 0.195-0.604, < 0.01), and subscale-to-total ( range = 0.408-0.876, < 0.01), respectively. Additionally, the factors accounted for 51.586%∼74.063% of the variance in each subscale, confirmatory factor analysis indicated the confirmatory model fitted data well and the scale had adequate construct validity. The study demonstrates FMSCA can serve as a valid and reliable measure of family management level for Chinese children with asthma.
本研究旨在在中国背景下开发并验证儿童哮喘家庭管理量表（FMSCA）。基于家庭管理风格框架（FMSF）模型，通过文献回顾以及对15名哮喘患儿照料者的访谈，初步生成了89个条目。经过两轮专家评估和一项预试验研究，该初步量表精简为82个条目，随后于2013年4月至7月施测于329名哮喘患儿照料者进行测试。进行项目分析和探索性因素分析以筛选条目，运用心理测量学技术（内部一致性、分半信度、重测信度、内容效度和结构效度）进行信效度分析。2014年8月至2015年12月，采用验证性因素分析对另外600名哮喘患儿及其父母进一步评估该量表的结构效度。结果：最终生成了一个由8个分量表（儿童身份认同、病情看法、管理思维模式、父母相互性、育儿理念、管理方法、家庭关注点和未来期望）组成的57个条目的FMSCA。其出色的内部一致性（克朗巴哈α系数=0.918）、非常好的分半信度（=0.802，<0.01）和重测信度（=0.857，<0.01）表明FMSCA具有令人满意的信度。该量表的条目内容效度指数（I-CVI）范围为0.83～1.00，量表内容效度指数（S-CVI）为0.807，表明具有良好的内容效度。通过条目与分量表（范围=0.513 - 0.865，<0.01）、分量表间（范围=0.195 - 0.604，<0.01）以及分量表与总量表（范围=0.408 - 0.876，<0.01）之间公认的相关系数确立了结构效度。此外，各因素在每个分量表中解释的方差变异为51.586%～74.063%，验证性因素分析表明验证模型与数据拟合良好，该量表具有足够的结构效度。该研究表明FMSCA可作为评估中国哮喘患儿家庭管理水平的有效且可靠的工具。
