To further establish the psychometric properties of the Parent Supervision Attributes Profile Questionnaire (PSAPQ), a questionnaire measure of parent supervision that is relevant to understanding risk of unintentional injury among children 2 through 5 years of age.
To assess test-retest reliability, parents completed the PSAPQ twice, with a one month interval. Internal consistency estimates for the PSAPQ were also computed. Confirmatory factor analyses were applied to the data to assess the four factor structure of the instrument by assessing the convergent and divergent validity of the subscales and their respective items.
Test-retest reliability and internal consistency scores were good, exceeding 0.70 for all subscales. Factor analyses confirmed the hypothesized model--namely that the 29 item questionnaire comprised four unique factors: protectiveness, supervision beliefs, risk tolerance, and fate influences on child safety.
Previous tests comparing the PSAPQ with indices of actual supervision and children's injury history scores revealed good criterion validity. The present assessment of the PSAPQ revealed good reliability (test-retest reliability, internal consistency) and established the convergent and divergent validity of the four factors. Thus, the PSAPQ has proven to have strong psychometric properties, making it a unique and useful measure for researchers interested in studying links between supervision and young children's risks of unintentional injury.
进一步确定父母监督属性概况问卷(PSAPQ)的心理测量特性,该问卷是一种用于测量父母监督情况的工具,对于理解2至5岁儿童意外伤害风险具有重要意义。
为评估重测信度,父母分两次填写PSAPQ,间隔一个月。同时计算PSAPQ的内部一致性估计值。对数据进行验证性因素分析,通过评估分量表及其各自项目的收敛效度和区分效度,来评估该工具的四因素结构。
重测信度和内部一致性得分良好,所有分量表得分均超过0.70。因素分析证实了假设模型,即这份包含29个条目的问卷由四个独特因素组成:保护意识、监督信念、风险容忍度以及命运对儿童安全的影响。
先前将PSAPQ与实际监督指标及儿童伤害史得分进行比较的测试显示出良好的效标效度。目前对PSAPQ的评估显示出良好的信度(重测信度、内部一致性),并确立了四个因素的收敛效度和区分效度。因此,PSAPQ已被证明具有强大的心理测量特性,使其成为对研究监督与幼儿意外伤害风险之间联系感兴趣的研究人员的一种独特且有用的测量工具。
