Understanding the processes through which interventions work for mothers of premature infants is necessary for the advancement of science and the translation of efficacious interventions into clinical practice settings.
To test a theoretical model examining the processes through which an educational-behavioral intervention program (Creating Opportunities for Parent Empowerment [COPE]) influences mothers' anxiety and depression 2 months after discharge of their premature infants from the neonatal intensive care unit (NICU).
A secondary analysis was conducted using data from a randomized controlled trial with 246 mothers of low-birth-weight preterm infants who were assigned randomly to COPE or placebo control conditions. Measures included mothers' stress in the NICU, mothers' anxiety and depression, and mothers' beliefs about their infants and their role. Observers blind to study group condition also rated the quality of mother-infant interaction in the NICU.
Structural equation modeling suggested that the model tested provided a reasonable fit to the data, chi2(64) = 97.67, p = .004, root mean square error of approximation = .046, comparative fit index = .97. Participation in COPE was both directly and indirectly, via associations with increased maternal beliefs and less maternal depression and anxiety in the NICU, related to mothers' decreased posthospital depression and anxiety. Participation in the COPE program also was associated with higher mother-infant interaction scores.
Implementation of COPE could lessen postdischarge maternal anxiety and depression, which may improve outcomes for both mothers and preterm infants.
了解干预措施对早产儿母亲起作用的过程,对于科学的进步以及将有效的干预措施转化为临床实践环境而言是必要的。
检验一个理论模型,该模型探讨一种教育行为干预项目(为父母赋权创造机会[COPE])在早产儿从新生儿重症监护病房(NICU)出院2个月后对母亲焦虑和抑郁的影响过程。
采用一项随机对照试验的数据进行二次分析,该试验有246名低体重早产儿母亲,她们被随机分配到COPE组或安慰剂对照组。测量指标包括母亲在NICU的压力、母亲的焦虑和抑郁,以及母亲对其婴儿及其角色的信念。对研究组情况不知情的观察者也对NICU中母婴互动的质量进行了评分。
结构方程模型表明,所检验的模型与数据拟合度较好,卡方(64)=97.67,p = 0.004,近似均方根误差 = 0.046,比较拟合指数 = 0.97。参与COPE项目,通过与母亲信念增强以及NICU中母亲抑郁和焦虑减少相关联,对母亲出院后的抑郁和焦虑减少有直接和间接的影响。参与COPE项目还与更高的母婴互动得分相关。
实施COPE项目可以减轻出院后母亲的焦虑和抑郁,这可能改善母亲和早产儿的结局。
