Background. Cognitive stimulation therapy is a psychosocial intervention shown to produce improvements in cognitive functioning and quality of life in people with dementia. The efficacy of this intervention with adults with Down syndrome has not been studied, despite the high risk of dementia in this group. The aim of this study was to evaluate the short-term efficacy of a group cognitive stimulation therapy programme as applied with healthy adults (aged 2:. 30 years) with Down syndrome and mild to moderate intellectual disabilities. Methods. Twenty-five participants were randomly allocated to a 14-session intervention group or control group engaged in usual activities. Outcomes included cognitive function (CAMCOGDS), adaptive behaviour (Vineland-II), and quality of life (ComQol-ID), assessed at baseline, post intervention, and 3-month follow-up . Assessors of cognitive functioning and quality of life were blind to allocation. Parametric statistics, including analysis of covariance, and nonparametric statistics were applied as appropriate. Results. All participants completed the study. Within-group analyses showed significant increases in intervention group cognitive scores immediately post intervention, and in quality of life ratings at follow-up, with large effect sizes. No significant between-group differences in change scores were found on the three outcomes at post intervention or follow-up. Significant between-group differences in favour of the intervention group were found immediately post intervention on the orientation subscale of the CAMCOG-DS and the place in community domain of the ComQol-ID, but were no longer significant at follow-up. The programme was well-received by participants. Conclusions. The findings do not provide evidence of efficacy, but are interpreted as encouraging with regard to the potential of the intervention to benefit adults with Down syndrome. Further study is needed, involving larger samples and with longer intervention and -follow-up periods, to assess efficacy both as a treatment for those with dementia and as a primary preventative intervention with this population.
