Summary
The (bio)psychosocial model for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) of Vercoulen et al. Fatigue: the subjective feeling of fatigue; fatigue subscale of the Checklist Individual Strength. Focusing on (Bodily) Symptoms: somatisation subscale of the Symptom Checklist. (Level of) Physical Activity: Sickness Impact Profile (SIP) subscale mobility (SIP-MOB) and the Physical Activities Rating Scale. (Functional) Impairment: impairment in daily life; subscale of activities at home of the SIP. Sense of Control (over Symptoms): selected items of the modified Pain Cognition List on a specific five-point scale. Causal Attributions: Causal Attributions List (high scores: physical attributions, low scores: psychosocial attributions).

Explanation: This is a biopsychosocial model that provides the rationale for the use of cognitive behavioral therapy and graded exercise therapy in patients with chronic fatigue syndrome and with chronic fatigue not caused by CFS. It was later refined by Wessely and Harvey.
