To examine the relationship between a cumulative risk model and caregiver quality of life (QOL) in pediatric asthma and determine whether caregiver QOL is predicted by a linear or quadratic model of cumulative risk.
One hundred and ninety-three families of children between the ages of 5 and 12 years with mild to severe asthma completed a background questionnaire and measures of QOL, asthma severity, family burden, and family stress. A cumulative risk model based on risk factors from these measures was calculated for each caregiver.
The cumulative risk model significantly predicted caregiver QOL as a quadratic function. Caregivers with numerous risk factors experienced a dramatic worsening of QOL.
Findings suggest that caregiver QOL is best predicted by the interaction and not the summation of these factors. Interventions focused on one area of family risk may be effective in reducing poor QOL in caregivers of children with asthma.
探讨累积风险模型与小儿哮喘照顾者生活质量（QOL）之间的关系，并确定照顾者的生活质量是由累积风险的线性模型还是二次模型预测。
193个有5至12岁轻度至重度哮喘儿童的家庭完成了一份背景调查问卷以及生活质量、哮喘严重程度、家庭负担和家庭压力的测量。为每位照顾者计算基于这些测量中的风险因素的累积风险模型。
累积风险模型作为二次函数显著预测了照顾者的生活质量。有大量风险因素的照顾者生活质量急剧恶化。
研究结果表明，照顾者的生活质量最好由这些因素的相互作用而非总和来预测。专注于家庭风险一个领域的干预措施可能有效降低哮喘儿童照顾者的不良生活质量。
