While there is a range of mainly non-pharmacological ‘treatments’ or ‘rehabilitation strategies’, only two have demonstrated reproducible evidence for their efficacy in non-severely affected CFS/ME patients: cognitive behaviour therapy (CBT) and graded exercise therapy (GET). Based on evidence from multiple randomised clinical trials (RCTs),18 a Cochrane systematic review (Chambers, Bagnall, Hempel, & Forbes, 2006; see also, Twisk, 2017, p. 3; Yancey & Thomas, 2012, p. 741–742) claimed that cognitive behaviour therapy and graded exercise therapy interventions showed promising results, appearing to reduce symptoms and improve function.19 According to the cognitive-behavioural model of illness, the patient's interpretation of symptoms plays an important role in perpetuating the illness (e.g. Sharpe, 1991; Wessely, 1989). Cognitive behaviour therapy aims to help the patient change the ‘negative beliefs’ that s/he has with the goal being either to reduce the symptoms and help the patient cope with the illness or to fully recover. On the other hand, graded exercise therapy is a physical activity that starts very slowly and gradually increases over time. Despite some limitations with the evidence and the generalisability of the findings, two reviews cautiously concluded that some patients may benefit from graded exercise therapy (Chambers et al., 2006; Edmonds, McGuire, & Price, 2004). Lastly, pacing is probably the most accepted form of treatment after cognitive behaviour therapy and graded exercise therapy. Pacing therapies encourages behavioural change, but unlike cognitive behaviour therapy, they acknowledge the typical patient fluctuations in symptom severity and delayed exercise recovery. Pacing's goal is to increase over time the level of ‘routine functioning’ of the individual. A randomised clinical trial concluded that pacing with graded exercise therapy had statistically better results than relaxation therapy (Deale, Husain, Chalder, & Wessely, 2001; Wallman, Morton, Goodman, Grove, & Guilfoye, 2004), and a 2008 patient survey by the Action for ME in fact found pacing to be the most helpful treatment.20
