The AIM-D is a novel patient-reported outcome (PRO) measure consisting of 11 items and 2 domains, Performance of Daily Activities (PDA; 7 items) and Physical Impairment (PI; 4 items), designed to evaluate the impact of migraine on activity impairment. 
To evaluate the psychometric properties and meaningful within-patient change (MWPC) estimates of the Activity Impairment in Migraine-Diary (AIM-D), using phase 3 trial data.
In a 12-week, double-blind, controlled trial (NCT03777059), participants with episodic migraine (EM) were randomized to receive atogepant 10mg QD, 30mg QD, 60mg QD, or placebo. AIM-D PDA and PI domains were key secondary endpoints and completed daily on an electronic diary. Psychometric properties were evaluated using confirmatory factor analysis (CFA), tests of reliability, validity (convergent and known-groups), responsiveness, and MWPC.
Of 910 participants enrolled, 719 were included in the PRO analysis (mean [range] age: 42 [18–73]; 88% were female). CFA supported the 2-domain factor structure. Both domains demonstrated good internal consistency (Cronbach’s alpha: PDA=0.98, PI=0.95), and test-retest reliability (intraclass correlation coefficients: PDA=0.77, PI=0.80). Construct validity was supported by moderate/strong correlations at baseline between the AIM-D domains and migraine/headache days (0.30–0.45) and activity level/limitation (0.33–0.92). Known-groups validity showed the 2 domain scores significantly differentiated groups defined by monthly migraine days (P<0.0001) and Patient Global Impression of Severity (PGI-S) (P<0.0001). Each domain score differed significantly across the anchors, PGI-S, Patient Global Impression of Change, and percent monthly migraine days. Anchor-based results demonstrated MWPC estimates of ≥9 points for the PDA domain and ≥6 points for the PI domain. 

Psychometric properties of the AIM-D were confirmed and MWPC estimates were established using phase 3 EM trial data. AIM-D is suitable for clinical trial endpoint measurement of the impact of migraine in patients with EM on performance of daily activities and physical impairment.
