Aim To test the situation‐specific theory of heart failure self‐care with structural equation modelling. Background Several authors have proposed theories on heart failure self‐care, but only the situation‐specific theory of heart failure self‐care by R iegel and D ickson is focused on the process that patients use to perform self‐care. This theory has never been tested with structural equation modelling. Design A secondary analysis of data from a cross‐sectional study. Methods 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 S elf‐ C are of H eart F ailure I ndex v.6·2. Results 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.’] Conclusion 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.
