Maslach Burnout Inventory - The Maslach Burnout Inventory (MBI) (Maslach et al., 1996) is a measure of work-related burnout (Crowder and Sears, 2017). It comprises twenty-two items, with three subscales which assess: (1) Emotional exhaustion, (2) Depersonalisation of service users, (3) Personal achievement. The scale is scored on a seven-point Likert scale (0 = never; 6 = everyday). The subscales highlight levels of burnout, with differing cut-off points specified for each subscale. The emotional exhaustion subscale ranges from low levels of burnout (seventeen or less), through moderate levels of burnout (eighteen to twenty-nine), to high levels of burnout (thirty or more). The depersonalisation of service users subscale ranges from low-level burnout (five or less), through moderate burnout (six to eleven), to high-level burnout (twelve or more).

Perceived Stress Scale - The Perceived Stress Scale (PSS) (Cohen et al., 1983) is widely used to assess an individual's perception of stress. It comprised ten items developed to assess how unpredictable or uncontrollable participants feel their lives are (Cohen, 1994). The scale is scored on a five-point Likert scale (0 = never; 4 = very often), with higher scores indicative of greater levels of stress.

Southampton Mindfulness Questionnaire - The Southampton Mindfulness Questionnaire (SMQ) (Chadwick et al., 2008) is a measure which assesses aspects of individual mindfulness resulting from unpleasant thoughts and images comprising of sixteen items. It is scored on a seven-point Likert scale (0 = Disagree totally; 6 = Agree totally), with higher scores indicative of greater mindfulness. The scale comprises four, four-item, subscales assessing (i) Mindful observation (SMQ-MO); (ii) Non-attachment (SMQ-NA); (iii) Aversion (SMQ-Av); (iv) Non-judgement (SMQ-NJ).
