The objective of the present study was to demonstrate the reciprocal relationships between family adaptation to illness and children's medication use over time among children who presented with wheezing illness in infancy but have varying illness outcomes by age 4.
A longitudinal design and latent growth curve models (LGM) were used to predict change in family and caregiver adaptation to illness and children's medication use over three years among 140 infants with wheezing, among families from low socioeconomic, multi-ethnic backgrounds.
One LGM predicted level and change (slope) of family adaptation to illness from children's baseline medication use. The second LGM predicted level and change (slope) of children's medication use from baseline family adjustment to illness. In both models, illness severity, caregivers' psychological resources, and emergency department use were covaried with the independent variable.
Two latent growth models were found to adequately fit the data and demonstrate full reciprocal relations between family adaptation to illness and children's medication use while accounting for baseline variables. Baseline measures of caregiver psychological functioning and illness severity were also significant predictors of family adaptation and children's medication use over time. The two models were not statistically different for children with and without active asthma at 4 years of age.
Findings support the reciprocal effects model of child and family influences on pediatric illness and underscore the importance of early indicators of individual and family functioning.
本研究的目的是证明在婴儿期出现喘息疾病但到4岁时疾病结局各异的儿童中,家庭对疾病的适应与儿童用药随时间的相互关系。
采用纵向设计和潜在增长曲线模型(LGM)来预测140名喘息婴儿家庭和照顾者对疾病的适应变化以及儿童在三年中的用药情况,这些家庭来自社会经济地位低、多民族背景的群体。
一个LGM从儿童的基线用药情况预测家庭对疾病适应的水平和变化(斜率)。第二个LGM从基线家庭对疾病的调整情况预测儿童用药的水平和变化(斜率)。在两个模型中,疾病严重程度、照顾者的心理资源和急诊室就诊情况都与自变量共同变化。
发现两个潜在增长模型能够充分拟合数据,并在考虑基线变量的情况下证明家庭对疾病的适应与儿童用药之间存在完全的相互关系。照顾者心理功能和疾病严重程度的基线测量也是家庭适应和儿童用药随时间变化的重要预测因素。对于4岁时患有和未患有活动性哮喘的儿童,这两个模型在统计学上没有差异。
研究结果支持儿童和家庭对儿科疾病影响的相互作用模型,并强调个体和家庭功能早期指标的重要性。
