Construct validity of the concepts of pain, self-care deficit and impaired mobility was examined in a study of 120 medical-surgical patients. Factors derived from a factor analysis of the empirical signs and symptoms were: pain-factor and self-care deficit/impaired mobility-factor. The pain-factor clearly showed discriminant validity by differentiating between those with and without Clinical Nurse Specialist (CNS)-identified diagnosis of pain. An overlap between the defining characteristics of the diagnoses of self-care deficit and impaired mobility has been suggested in the present sample of patients. Limitations of the study and recommendations for further research are described.
在一项针对120名内科-外科患者的研究中，对疼痛、自理缺陷和活动障碍概念的结构效度进行了检验。通过对实证体征和症状进行因子分析得出的因素为：疼痛因子和自理缺陷/活动障碍因子。疼痛因子通过区分有和没有临床护理专家（CNS）确诊疼痛的患者，清楚地显示出判别效度。在本患者样本中，已表明自理缺陷和活动障碍诊断的定义特征之间存在重叠。描述了该研究的局限性和进一步研究的建议。
