Figure 2: effect sizes of the difference between migraine patients compared with healthy controls, past psychopathology and current psychopathology.
Cohen’s d indicates a small effect if it is around 0.2, a moderate effect if it is around 0.5 and a large effect if it is greater than 0.8. * indicates p<0.001
MASQ-PA= positive affect subscale; MASQ-NA = negative affect subscale; MASQ-SA = somatic arousal subscale
Within the group of migraine patients (n=3174), general and migraine specific determinants for the three subscales of affective disorders were analyzed using multivariate linear regression (table 3). Age was significantly associated with lack of positive affect and negative affect. Gender was significantly associated with somatic arousal. Migraine frequency and cutaneous allodynia, but not migraine subtype, were associated with all three symptom dimensions of the affective disorder questionnaire.
