Phase one (tailoring) data collection steps and outcomes

Step	Outcomes (measures)
e-TUDE (clinician)
Study entry	• Self-reported sociodemographic characteristics • Self-reported interest for each of the topics addressed in the C-DB on a 1–10 visual analogue scale
Pre training	• Role preference scale [63] • Perceptions of being able to adopt shared decision-making using the ICanSDM scale • Intention to engage senior patients living with dementia and their caregivers in decision-making about choosing a health intervention, based on the TPB [37, 38]
Post training	• Satisfaction with e-TUDE (1–5 smiley face scale) • Usability of e-TUDE, based on the Technology Acceptance Model (TAM-2) [64–66] • Role preference scale [63] • Perceptions of being able to adopt shared decision making using the ICanSDM scale • Intention to engage senior patients living with dementia and their caregivers in decision-making about choosing a health intervention, based on the TPB [37, 38]
C-DB (clinician questionnaire)
Study entry questionnaire	• Self-reported sociodemographic characteristics • Self-reported interest for each of the topics addressed in the C-DB on a 1–10 visual analogue scale
After reviewing each C-DB	• Satisfaction with C-DB (1–5 smiley face scale) • C-DB usability based on the Technology Acceptance Model (TAM-2) [64–66] • Intention to use what was learned from the C-DB to explain to patients the benefits and harms of the options, based on the TPB [37, 38] • Value of the evidence presented in the C-DB, measured using the clinician version of the IAM [43, 67]
P-DB (Patients and caregivers)
Able patient	• Socio-demographic characteristics of the patient self-reported by the patient • Satisfaction with the P-DB (1–5 smiley face scale) • P-DB usability based on the Technology Acceptance Model (TAM-2) [64–66] • Value of the evidence presented in the P-DB, measured using the patient version of the IAM [67]
Caregiver of able patient	• Sociodemographic characteristics of the caregiver: self-reported by the caregiver • Satisfaction with the P-DB (1–5 smiley face scale) • P-DB usability based on the Technology Acceptance Model (TAM-2) [64–66] • Value of the evidence presented in the P-DB, measured using the caregiver version of the IAM [67]
Caregiver of unable patient	• Self-reported sociodemographic characteristics of the caregiver • Sociodemographic characteristics of the patient reported by the caregiver • Satisfaction with the P-DB (1–5 smiley face scale) • P-DB usability based on the Technology Acceptance Model (TAM-2) [64–66] • Value of the evidence presented in the P-DB, measured using the caregiver version of the IAM [67]
