People with aphasia after stroke are typically excluded from studies of anxiety prevalence and so the number of those affected is unclear. Aims: To make a preliminary estimate of the prevalence of significant anxiety in people with aphasia after stroke. Methods & Procedures: Carers to community-dwelling people with aphasia after stroke, N = 111, completed the Behavioural Outcomes of Anxiety scale (BOA), a modified Hospital Anxiety and Depression Scale–Anxiety sub-scale (HADS-A), and a modified Generalised Anxiety Disorder-7 item (GAD-7) scale to determine the presence of significant anxiety in the person for whom they cared. Associates of anxiety in people with aphasia after stroke were also investigated. Outcomes & Results: The BOA identified 49 people (44%) as having significant anxiety. Findings for the HADS-A = 46 (41%) were similar; however, for the GAD-7, the rate was substantially lower = 18 (16%). Anxiety after stroke had a modest but significant association with younger age (all measures) and with the Frenchay Aphasia Severity Test scores (BOA and HADS-A only). Conclusions: The prevalence of anxiety in people with aphasia after stroke is high and likely higher than in those with stroke with no aphasia when measured using a validated tool for this population. Risk factors for anxiety appear to be severity of aphasia and younger age. This finding should be tempered by the fact that this is a preliminary study in a relatively small sample consisting of those attending stroke groups and the use of caregiver assessments may overestimate the prevalence of mood disorder.
