HF Self-care Practice Assessment Questionnaire (HFSCPA-Q) adapted from Riegel et al. (2004) and Jaarsma et al. (2003) (link) was used to measure self-care practices. The domains were generated according to the four adaptive modes as described in RAM. These modes were classified into three themes: Self-care maintenance, self-care monitoring, and self-care management. Additionally, a table of specifications was created in order to ensure that all items were relevant to the research question. Multiple interviews were conducted with cardiologists, cardiology nurses, clinical resource nurses as well as patients, and the findings were used to revise and organize the items in a suitable sequence.
The Heart Failure Self-care Knowledge Assessment Questionnaire (HFSCKA-Q) was adapted from the Dutch Heart Failure Knowledge Scale (Van der Wal et al., 2005 (link)). Many questions were either reviewed or deleted after discussion with patients and experts in order to align with the conceptual framework of the study as well as the socio-cultural considerations of the country. The knowledge questionnaire composed of two sections: (1) demographic data sheet and (2) HF self-care knowledge. The following domains were included after a review of international and local guidelines: general information about HF; maintaining a low sodium diet; monitoring fluid intake and weight daily; medication compliance; exercise and activity; smoking cessation strategies and symptom recognition and management; social support.
