SA = Satisfaction subscale; A = Ability subscale; ST = Strategy subscale. 1 = Satisfaction; 2 = Prospective memory mistakes; 3 = Retrospective memory mistakes; 4 = External Strategy; 5 = Internal Strategy; 6 = Frustration
We marked with bold those items that loaded different scale in our analysis than in the original version of MMQ
