RESUMEN
BACKGROUND: Heart failure (HF) self-care is key to managing symptoms, but current HF knowledge instruments are at risk for social desirability bias (ie, tendency to respond in a way that is viewed favorably). Vignettes may be a useful method to mitigate this bias by measuring knowledge via scenarios in which individuals with HF are invited to respond to fictional characters' self-management problems rather than disclosing their own practices. OBJECTIVE: The aims of the study were to develop and test the content validity of vignettes measuring individuals' knowledge of HF symptom self-management. METHODS: The study had 3 phases. In phase 1, two vignettes were developed. One focused on psychological symptom self-management (ie, anxiety, depression), and the other focused on physical symptom self-management (ie, edema, fatigue). In phase 2, the research team and lay experts made improvements to the vignettes' readability. In phase 3, five HF self-care nurse experts evaluated the vignettes' clarity and importance with a 3-point Likert-type scale using Delphi methods. We calculated the vignettes' content validity using the scale-level content validity index. RESULTS: The final content validation encompassed 2 Delphi rounds (phase 3), yielding a scale-level content validity index of 0.92 and 0.94 for the psychological and physical symptom vignettes, respectively. These results indicate excellent initial content validity. CONCLUSIONS: The content of vignettes measuring individuals' knowledge of HF symptom self-management is valid based on the opinions of nurse experts. The vignettes offer a promising method to assess knowledge about HF self-care management without the pressure of disclosing individual patient practices.
RESUMEN
AIMS: Simulation offers a feasible modality to prepare nurses for challenges communicating with patients with dementia. Elderspeak communication is speech that sounds like baby talk and can lead to rejection of care by patients with dementia. However, it is unknown if simulation can be used to capture elderspeak communication in dementia care. The purpose of this mixed-methods study was to determine if simulation accurately captures elderspeak communication by nursing staff in hospital dementia care. DESIGN: A 3-part mixed-methods design in which (1) three dementia care simulations were designed and validated by a panel of experts, (2) communication by nursing staff completing each simulation was quantitatively compared to communication during actual patient care, and (3) views on the realism were explored using within- and across-case coding. METHODS: Three simulations using different modalities (manikin, role-play, and standardised patient) were designed and validated with eight experts using the Lynn Method. Ten nursing staff were audio-recorded and their communication was coded for elderspeak communication. Results for each simulation were compared using Wilcoxon signed-rank test to recordings taken during actual dementia care encounters. Debriefings were coded for realism and results were converged. RESULTS: The average time using elderspeak during naturalistic care was 29.9% (SD = 20.9%) which did not differ from the average amount of elderspeak used across the three simulations modalities which ranged from 29.1% to 30.4%. Qualitative results suggested a lack of realism with the manikin condition and the nursing staff indicated preference for the simulation with the standardised patient. CONCLUSIONS: Communication elicited in the dementia care simulations was congruent to communication produced in actual dementia care but preference was for the standardised patient. IMPLICATIONS FOR PATIENT CARE: Elderspeak communication can be accurately produced in the simulated environment which indicates that simulation is a valid method for person-centred communication training in nursing staff. IMPACT: Simulation offers a feasible modality to prepare nurses for challenges communicating with patients with dementia. Elderspeak communication is speech that sounds like baby talk and can lead to rejection of care by patients with dementia. However, it is unknown if simulation can be used to capture elderspeak communication in dementia care. Elderspeak communication captured in the simulated environment was congruent to communication nursing staff use during actual patient care to hospitalised persons living with dementia. This study empirically identifies that communication is elicited in similar patterns by nursing staff in the simulated environment compared to the naturalistic care environment which demonstrates that simulation can be used as a valid tool for education and research on person-centred communication.
