Objective The objective of this study was to evaluate peer support and reminiscence therapy, separately and together, in comparison with usual care for people with dementia and their family carers.
Design Factorial pragmatic randomised trial, analysed by treatment allocated, was used for this study.
Setting The trial ran in Community settings in England.
Participants People with dementia and their family carers were the participants.
Interventions Treatment as usual (TAU) plus one of the following: one-to-one peer support to family carers from experienced carers (Carer Supporter Programme; CSP), group reminiscence therapy (Remembering Yesterday, Caring Today; RYCT) for people with dementia and carers, both or neither.
Main outcome measures Primary outcomes included health-related quality of life (SF-12) for carers and quality of life (QoL-AD) for people with dementia; secondary outcomes included quality of relationship for carers and people with dementia; both were collected by blinded assessors at baseline, 5 and 12 months (primary end point).
Results Of 291 pairs recruited, we randomised 145 (50%) to CSP (71% uptake) and 194 (67%) to RYCT (61% uptake). CSP and RYCT, separately or together, were not effective in improving primary outcomes or most secondary outcomes. For CSP versus ‘no CSP’, adjusted difference in means was 0.52 points on the SF-12 (95% CI −1.28 to 2.32) and −0.08 points on the QoL-AD (95% CI −1.70 to 1.56). For RYCT versus ‘no RYCT’, the difference was 0.10 points on the SF-12 (95% CI −1.72 to 1.93) and 0.51 points on the QoL-AD (95% CI −1.17 to 2.08). However, carers reported better relationships with the people with dementia (difference 1.11, 95% CI 0.00 to 2.21, p=0.05). Comparison of combined intervention with TAU, and of intervention received, suggested differential impacts for carers and persons with dementia.
Conclusions There is no evidence from the trial that either peer support or reminiscence is effective in improving the quality of life.

Contributors GC, BW, IR and MO participated in the design and conduct of all stages of the research. JH was programme coordinator, ZH was trial statistician, MK was health economics adviser and IR was methodological adviser. JW, NC and KB were trial managers at different states of the research. RYCT Consultant and trainer was Pam Schweitzer. JW oversaw provision of the RYCT intervention throughout the study, with groups led locally by Yvette Kusel, Janet Jones, Caroline O'Haire, Jackie Illes, Barbara Parkinson, Dianne Collins, Gurjinder Loyal and Rebecca Whitaker. Shaheen Ahmed gathered data on CSP intervention provision from local CS Coordinators Anne Loxham, Mary Woodford, Maggie Playle, Liz Sturgess, Doreen Harrison and Lumbini Vithana. Researchers Nadia Crellin, Elizabeth Harte, Alexandra Feast, Nina Melunsky, Emma Patten, Teresa Sullivan, James Sinclair and Deepak Sankhla collected and entered data from participating carers and people with dementia. GC, KB, NC, ZH, JH, MK, IR, JW, BW and MO participated in all stages of manuscript preparation and approved the final version. GC is the guarantor.
