To develop and evaluate the psychometric properties of a scale termed the Maternal Worry Scale (MWS) designed to measure maternal worry about children with chronic illnesses.
The sample consisted of 140 mothers of young children (mean age 8.2 years, 64% female) with a chronic illness (juvenile rheumatoid arthritis, diabetes, or sickle cell disease). Maternal worry, depression, and anxiety, as well as information about the child's health and behavior, were assessed through structured interviews.
The MWS had good internal consistency (alpha = .94) and test-retest reliability (r = .84). Analyses indicated a single-factor structure for the MWS. Estimates of construct validity were quite positive: the MWS was moderately correlated with parental depression (r = .34-.39), anxiety (r = .27), and maternal report of child behavior problems (r = .25 [externalizing], r = .46 [internalizing]).
The results suggest that the MWS is a useful, reliable, and valid scale for measuring worry of mothers raising children with chronic health conditions.
开发并评估一个名为“母亲担忧量表（MWS）”的量表的心理测量特性，该量表旨在测量母亲对患有慢性疾病孩子的担忧程度。
样本包括140名患有慢性疾病（幼年类风湿性关节炎、糖尿病或镰状细胞病）幼儿（平均年龄8.2岁，64%为女性）的母亲。通过结构化访谈评估母亲的担忧、抑郁和焦虑，以及有关孩子健康和行为的信息。
MWS具有良好的内部一致性（α = 0.94）和重测信度（r = 0.84）。分析表明MWS具有单因素结构。结构效度估计结果相当积极：MWS与父母抑郁（r = 0.34 - 0.39）、焦虑（r = 0.27）以及母亲报告的孩子行为问题（r = 0.25[外化问题]，r = 0.46[内化问题]）呈中度相关。
结果表明，MWS是一个用于测量抚养患有慢性健康问题孩子的母亲担忧程度的有用、可靠且有效的量表。
