Cognitive–behavioural therapy for anxiety in dementia: pilot randomised controlled trial

Abstract

BackgroundAnxiety is common and problematic in dementia, yet there is a lack of effective treatments.AimsTo develop a cognitive–behavioural therapy (CBT) manual for anxiety in dementia and determine its feasibility through a randomised controlled trial.MethodA ten-session CBT manual was developed. Participants with dementia and anxiety (and their carers) were randomly allocated to CBT plus treatment as usual (TAU) (n= 25) or TAU (n= 25). Outcome and cost measures were administered at baseline, 15 weeks and 6 months.ResultsAt 15 weeks, there was an adjusted difference in anxiety (using the Rating Anxiety in Dementia scale) of (–3.10, 95% CI −6.55 to 0.34) for CBT compared with TAU, which just fell short of statistical significance. There were significant improvements in depression at 15 weeks after adjustment (–5.37, 95% CI −9.50 to −1.25). Improvements remained significant at 6 months. CBT was cost neutral.ConclusionsCBT was feasible (in terms of recruitment, acceptability and attrition) and effective. A fully powered RCT is now required.
