Design outcomes

Primary

MeasureTime frame
1. Recruitment Effectiveness: Demographic representativeness of recruited participants measured using an analysis of recruitment strategies and eligibility criteria after the recruitment phase 2. Participant Retention: Retention rate and reasons for attrition measured using an evaluation of retention strategies and analysis of attrition trends throughout the intervention period, with a final assessment at study completion 3. Intervention Completion and Exposure: The number of sessions attended by participants measured by monitoring attendance and engagement levels through session logs and exit interviews continuously throughout phases 2+3, with final analysis post-intervention 4. Intervention Acceptability: Participant feedback on acceptability measured using qualitative data through semi-structured exit interviews at the end of phases 2+3 5. Safety Monitoring: Incidence of adverse events and serious adverse events measured by auditing and monitoring adverse events with causality assessment continuously throughout the study, with final review at study completion

Secondary

MeasureTime frame
The research on the clinical outcome measures to be used in the single-arm feasibility trial has not been finalised, as the decisions will also depend on the conversations and discussions with focus group participants (family carers, PLWD and clinicians) in phase 1. The following suggested secondary outcome measures will be assessed at baseline and post-intervention: 1. Adaptation for Hallucinatory Experiences: The severity and frequency of hallucinatory experiences across all five senses measured using the Adapted Hamilton Program for Voices Questionnaire (HPSVQ). 2. Family Carer Quality of Life: The quality of life of family carers measured using the C-DEMQOL questionnaire 3. The Person with Dementia's Quality of Life: The quality of life of the person with dementia measured using the DEM-QOL questionnaire 4. Carer Burden: Level of burden experienced by the carer measured using the Zarit Carer Burden Interview 5. Depression Symptom Severity: The severity of depression symptoms measured using the PHQ-9 self-report measure 6. Anxiety Symptom Severity: Severity of anxiety symptoms measured using the GAD-7 measure
