To test the validity of the definition, related factors, and defining characteristics of the nursing diagnosis of ineffective breastfeeding. Also, to test whether defining characteristics relevant to the interruption of breastfeeding may be included in the diagnosis of ineffective breastfeeding.
A methodologic study using a two-stage Delphi process.
Sixty-six nurses in the first round of the Delphi process and 34 nurses in the second round.
A Likert-like scale was used to measure nurse experts' opinions as to how reflective each defining characteristic was of ineffective breastfeeding.
The definition of ineffective breastfeeding was simplified, related factors were added, and defining characteristics were clarified. Two characteristics of interruption of breastfeeding were found to be relevant to ineffective breastfeeding, but were considered minor rather than major.
The definition, related factors, and defining characteristics of ineffective breastfeeding have been clarified and validated by nurse experts, but they need further validation by breastfeeding women.
检验母乳喂养无效这一护理诊断的定义、相关因素及定义特征的有效性。同时，检验与母乳喂养中断相关的定义特征是否可纳入母乳喂养无效的诊断中。
采用两阶段德尔菲法的方法学研究。
德尔菲法第一轮有66名护士，第二轮有34名护士。
使用类似李克特量表来衡量护士专家对每个定义特征反映母乳喂养无效程度的看法。
简化了母乳喂养无效的定义，增加了相关因素，并明确了定义特征。发现母乳喂养中断的两个特征与母乳喂养无效相关，但被认为是次要而非主要特征。
护士专家已对母乳喂养无效的定义、相关因素及定义特征进行了明确和验证，但仍需由母乳喂养的女性进行进一步验证。
