Health Coaching With Hospitalised Chronic Heart Failure Patients

Data collection: Data collection was divided into four times: T0, T1, T2 and T3. T0 and T2 corresponded to preintervention data and T1 and T3 to postintervention data (T1 after the training and T3 one year later, after the whole intervention implementation). At all four times, the I-CEpSE (competent health education practice, (in Spanish, 'Instrumento Competencia de Educación para la Salud del profesional de Enfermería'))instrument was collected as a means to measure self-reported nurses' knowledge, skills, and attitudes regarding competency-based health education. This questionnaire includes 58 items grouped into 3 domains: 1) Knowledge (items 1-23); 2) Skills (items 24-49); and 3) Attitudes (items 50-58). In turn, the skills domain is divided into two dimensions: personal/social skills (items 24-34) and educational skills (items 35-49). This is a validated instrument with good psychometric properties, internal consistency was high for each total scale (cognitive domain: Cronbach α = 0.95; psychomotor: Cronbach α = 0.95; attitudinal and affective: Cronbach α = 0.90) and for all factors (Cronbach α values ranged from 0.81-0.95). Ethical considerations: This study conformed to the principles set out in the Declaration of Helsinki and was approved by the centre's board and by the Research Ethics Committee (code 2019.066). Data custody complied with Organic Law 3/2018 on data protection (LOPDE). Informed consents were given to all participants. They were informed verbally and in writing about their free participation, the confidentiality and anonymity of the data and its use for scientific purposes.
