To test the situation-specific theory of heart failure self-care with structural equation modelling.
Several authors have proposed theories on heart failure self-care, but only the situation-specific theory of heart failure self-care by Riegel and Dickson is focused on the process that patients use to perform self-care. This theory has never been tested with structural equation modelling.
A secondary analysis of data from a cross-sectional study.
Patients with heart failure were recruited in 21 cardiovascular centres across Italy during 2011. Data were collected with a sociodemographic questionnaire, chart abstraction for clinical data and the Self-Care of Heart Failure Index v.6.2.
A sample of 417 participants was enrolled in the study (59% males, mean age 72 years). The following propositions were tested and supported: Symptom monitoring correlates with treatment adherence; symptom monitoring and treatment adherence have a direct, positive relationship with symptom recognition and evaluation that in turn have a direct, positive relationship with treatment implementation; treatment implementation has a direct, positive relationship with treatment evaluation. In addition, the following three relationships were found: Symptom monitoring has a direct, positive relationship with treatment implementation; symptom recognition and evaluation have direct, positive relationships with treatment evaluation and symptom monitoring correlates with treatment evaluation. [Correction added on 9th April 2013, after first online publication: '…symptom monitoring correlates with treatment implementation.' has been corrected to read '…symptom monitoring correlates with treatment evaluation.']
The data support the situation-specific theory of heart failure self-care with the addition of three new relationships that emerged from the analysis. Results of this study lend further support to the use of the situation-specific theory of heart failure self-care in research and practice.
运用结构方程模型检验心力衰竭自我护理的情境特定理论。
几位作者提出了心力衰竭自我护理理论，但只有 Riegel 和 Dickson 的心力衰竭自我护理情境特定理论专注于患者进行自我护理的过程。该理论从未通过结构方程模型进行过测试。
对一项横断面研究数据的二次分析。
2011 年，在意大利的 21 个心血管中心招募心力衰竭患者。使用社会人口统计学问卷、临床数据图表摘录和心力衰竭自我护理指数 v.6.2 收集数据。
该研究纳入了 417 名参与者（59%为男性，平均年龄 72 岁）。检验并支持了以下假设：症状监测与治疗依从性相关；症状监测和治疗依从性与症状识别和评估呈直接正相关，而症状识别和评估又与治疗实施呈直接正相关；治疗实施与治疗评估呈直接正相关。此外，还发现了以下三个关系：症状监测与治疗实施呈直接正相关；症状识别和评估与治疗评估呈直接正相关，症状监测与治疗评估呈正相关。
数据支持心力衰竭自我护理的情境特定理论，分析中还出现了三个新的关系。本研究的结果进一步支持在研究和实践中使用心力衰竭自我护理的情境特定理论。
