METHODS: this methodological study was conducted in two stages: theory development and evaluation. Dorothea Orem\'s General Nursing Model was used as the theoretical-conceptual foundation. Evaluation was conducted using the Delphi method with seven judges, and consensus was achieved when the Content Validity Index of the evaluated items was ≥ 0.80.
RESULTS: the theory identified 20 elements of the nursing diagnosis \"Disrupted Mother-Fetus Dyad Risk\" (10 risk factors, 4 at-risk populations, and 6 associated conditions), 14 propositions, and 1 pictogram. After two rounds of evaluation, the theory was considered consistent, with consensus reached for all items, each achieving a Content Validity Index ≥ 0.80.
CONCLUSIONS: the Middle-Range Theory included biopsychosocial factors explaining the nursing phenomenon \"Disrupted Mother-Fetus Dyad Risk,\" which aids in nurses\' diagnostic reasoning.
方法:该方法学研究分两个阶段进行:理论发展和评估。DorotheaOrem的一般护理模型被用作理论概念基础。使用德尔菲法与7名法官进行评估,当评价项目的内容有效性指数≥0.80时,达成共识。
结果:该理论确定了护理诊断“母胎损伤风险”的20个要素(10个危险因素,4个高危人群,和6个相关条件),14个命题,和1个象形图。经过两轮评估,这个理论被认为是一致的,就所有项目达成共识,每个达到含量有效性指数≥0.80。
结论:中距离理论包括解释护理现象的生物心理社会因素,“这有助于护士的诊断推理。
