The Beck Depression Inventory 11 (BDI-II) is a 21 items self-report scale to assess the intensity of depression. Each item is a list of four statements arranged in increasing severity about a symptom of depression. Score range between 0-63 with higher score indicating greater severity. Normally completed in 5-10 minutes.

The Beck Anxiety Inventory (BAI) is a self-report 21-item scale for measuring anxiety. The questions ask about symptoms of anxiety the subject has had during the past week. Each question is scored between 0 (mild) and 3 (severe) and a total score will vary between 0-63. Higher scores indicate more severe anxiety symptoms.

The DASS is a set of three self-report scales designed to measure depression, anxiety and stress. Each of the three DASS scales contains 14 items, divided into subscales of 2-5 items with similar content. The Depression scale assesses dysphoria, hopelessness, devaluation of life, self-deprecation, lack of interest/involvement, anhedonia, and inertia. The Anxiety scale assesses autonomic arousal, skeletal muscle effects, situational anxiety, and subjective experience of anxious affect. The Stress scale is sensitive to levels of chronic non-specific arousal. It assesses difficulty relaxing, nervous arousal, and being easily upset/agitated, irritable/over-reactive and impatient. Subjects are asked to use 4-point severity/frequency scales to rate the extent to which they have experienced each state over the past week. Scores for Depression, Anxiety and Stress are calculated by summing the scores for the relevant items.

The 5-level EQ-5D version (EQ-5D-5L) comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.

The Stroke Impact Scale (SIS) is a self-report, health status measure for people affected by stroke. It was designed to assess strength, hand function, activities of daily living, mobility, communication, emotion, memory and thinking, and participation. The SIS can be used both in clinical and research settings. It contains 59 items and assesses 8 domains. Each item is rated using a 5-point Likert scale. A final single-item question assesses the individual's perception of recovery from stroke, measured using a visual analogue scale, where 0 = no recovery & 100 = full recovery. The scale is normally completed in 15-20 minutes.

Focus Groups (FGs) will be used to collect qualitative data.
