| - | ===== Background ===== | + | ===== Calculation of CFS diagnostic score ===== |
| + | To identify participants who get a positive Chronic Fatigue Syndrome (CFS) diagnostic score, the 1994 Centers for Disease Control and Prevention ([[fatigue_CDC|CDC]]) criteria are taken into consideration. More specifically, participants have to meet three specific criteria in order to receive the CFS diagnosic score. In other words, if all criteria are met the participant receives a positive diagnostic score and when at least one of the criteria is zero the participant receives a negative CFS diagnostic score. Below the three criteria are highlighted including details on the included statements in the calculation. | ||

| + | The eight additional symptoms are as follows: sore throat, tender lymph nodes, muscle pain, joint pain, headaches, unrefreshing sleep, unusual fatigue after exertion, forgetfulness, and difficulty concentrating. Please note: forgefulness and difficulty concentrating is treated as one symptom. | ||
