MASQ-PA= positive affect subscale; MASQ-NA = negative affect subscale; MASQ-SA = somatic arousal subscale
Further pairwise comparison with migraine as reference group is depicted in figure 2. Migraine patients were significantly different (p<0.001) for all comparisons to the two psychopathology groups and healthy controls, except for the lack of positive affect compared with the past psychopathology group. In figure 2, differences between the groups are displayed as Cohen’s d, a measure of effect size, showing that scores on the lack of positive affect (Cohen’s d=0.07) and negative affect (Cohen’s d=0.30) dimensions for migraine patients are most closely related to the past psychopathology group. For the somatic arousal subscale scores migraine patients are closer related to current psychopathology (Cohen’s d=0.25).
