Participant counts for each measure differ from the total number of participants (patients N=17, controls N=15) because some participants did not complete all questionnaires. Abbreviations: PANAS, Positive and Negative Affect Schedule; BIS/BAS, Behavioral Inhibition System/Behavioral Activation System; PROMIS, Patient-Reported Outcomes Measurement Information System; STAI, State-Trait Anxiety Inventory; FAF, Fibromyalgia Assessment Form; BDI, Beck Depression Inventory; POMS, Profile of Mood States; BPI, Brief Pain Inventory; sd, standard deviation. Data are presented for descriptive purposes only, therefore significance values (P-Value) shown are not corrected for multiple comparisons.
