Plain English Summary
Background and study aims
The majority of at-home care for people with dementia is given by family members but numerous studies have shown that dementia carers experience high levels of burden, which results in poor health outcomes and quality of life for them, and earlier institutionalisation for the person with dementia. Poor health outcomes include an increased risk of psychological illnesses such as depression and anxiety and an overall increased risk of illness and death. Interventions that address carer burden are therefore essential. This study aims to help carers of people with dementia by increasing their knowledge about the trajectory of dementia, improving their participation in decision-making about community services, reducing any feelings of conflict and anxiety they may have about making care decisions, and increasing the early use of community services. We aim to do this by providing carers with the GOLD Book decision aid (GBDA).
Who can participate?
Primary carers of people with dementia living in the community, aged 18 or over.
What does the study involve?
Carers are randomly allocated to either the intervention group (who receive the GBDA in the mail) or to the control group (who receive the GBDA at the end of data collection). Participants are interviewed at the beginning, middle and end of this three-month study about their role as a carer for a person with dementia. The interviews take about 45 minutes to complete. We assess the carers’ health and stress levels, knowledge of dementia, service needs and whether they are satisfied, and how they are making decisions about care and services. At the end of the study some participants are also asked some specific questions about the book.
What are the possible benefits and risks of participating?
All participants in the study will receive a copy of the book (GBDA) that can help them think through service and support decisions. The study has no particular risks for participants, but the interview may evoke uncomfortable feelings. Assistance will be provided by the project staff to any participants who experience emotional discomfort as a result of the study.

Primary outcome measure
The Modified Carergiver Strain Index (MCSI) is a 13 item measure used to measure carer stress. The outcomes of the intervention will be assessed by comparisons between control and intervention groups at baseline (Time 1) and three months post intervention (Time 3), with the intervention given one week after baseline data is collected. Surveys will be delivered through face to face and phone interview.
Secondary outcome measures
1. Carer decisional state will be ascertained using the Decisional Conflict Scale (O'Connor 1993/2005), a 16 item survey that yields a 5 scale measure of decisional uncertainty, and the Control Preferences Scale (Degner et al. 1997), which measures treatment decision making using 5 response statements.
2. Knowledge of dementia using a researcher generated knowledge survey
3. The outcomes of the intervention will be assessed by comparisons between control and intervention groups at baseline (Time 1) and three months post intervention (Time 3), with the intervention given one week after baseline data is collected. Surveys will be delivered through face to face and phone interview.
