Treatments recommended by National Institute for Health Care Excellence (NICE 2007) include Cognitive Behavioural Therapy (CBT) and behavioural approaches (Graded Exercise Therapy, GET, and activity management) (Brigden et al., 2017). All treatments offer advice on sleep, symptom management and co-morbidities such as mood disorders and pain. CBT, which has the strongest evidence base (Al-Haggar et al., 2006; Chalder et al., 2010; Lloyd et al., 2012; Nijhof et al., 2012; Stulemeijer et al., 2005), supports the young person to identify and change fatigue-related cognitions and gradually resume activities (Brigden et al., 2017). GET aims to stabilise physical activity levels, before gradually increasing activity at a manageable rate (White et al., 2007). Activity Management is a goal-oriented and person-centred approach which establishes a baseline for all activity (physical, cognitive and emotional), which is then increased (White et al., 2007).
