Being able to do things other kids do is the desire of school-age children and adolescents with asthma. In a phenomenology study, adolescents identified participation in life activities as the outcome variable and primary motivator for behavioral changes in coming to accept asthma as a chronic condition. In preparation for testing an acceptance model for older school-age children and early adolescents diagnosed with asthma, the Participation in Life Activities Scale was developed. The purposes of this paper are to describe development, and report on face and content validity of the scale designed to measure one aspect of quality of life defined as level of unrestricted involvement in chosen pursuits.
Items generated for the instrument evolved from statements and themes extracted from qualitative interviews. Face and content validity were evaluated by eight lay reviewers and 10 expert reviewers. Rate of accurate completion was computed using a convenience, cross-section sample consisting of 313 children and adolescents with asthma, ages 9-15 years, drawn from three studies. Preliminary cross-group comparisons of scores were assessed using t-tests and analysis of variance.
Face and content validity were determined to be highly acceptable and relevant, respectively. Completion rate across all three studies was 97%. Although cross-group comparisons revealed no significant differences in overall participation scores based on age, race or residence groupings (p > .05), significant difference were indicated between males and females (p = .02), as well as the highest and lowest socioeconomic groups (p = .002).
Assessing content validity was the first step in evaluating properties of this newly developed instrument. Once face and content validity were established, psychometric evaluation related to internal consistency reliability and construct validity using factor analysis procedures was begun. Results will be reported elsewhere.
能够像其他孩子一样行事是患有哮喘的学龄儿童和青少年的愿望。在一项现象学研究中，青少年将参与生活活动确定为结果变量，也是他们在逐渐接受哮喘为慢性病过程中行为改变的主要动机。为准备测试针对被诊断患有哮喘的大龄学龄儿童和青少年的接受模型，开发了生活活动参与量表。本文的目的是描述该量表的开发过程，并报告其表面效度和内容效度，该量表旨在测量生活质量的一个方面，即定义为在所选追求中不受限制的参与程度。
该工具生成的条目源自定性访谈中提取的陈述和主题。由八名外行评审员和十名专家评审员对表面效度和内容效度进行评估。使用来自三项研究的313名9至15岁哮喘儿童和青少年组成的便利横断面样本计算准确完成率。使用t检验和方差分析对分数进行初步跨组比较评估。
表面效度和内容效度分别被确定为高度可接受和相关。所有三项研究的完成率为97%。尽管跨组比较显示，基于年龄、种族或居住分组的总体参与得分没有显著差异（p>.05），但男性和女性之间（p=.02）以及社会经济最高和最低组之间存在显著差异（p=.002）。
评估内容效度是评估这一最新开发工具特性的第一步。一旦确定了表面效度和内容效度，就开始使用因子分析程序对与内部一致性信度和结构效度相关的心理测量进行评估。结果将在其他地方报告。
