Objective: To provide more insight into subjective attention complaints in a healthy adult and elderly population and how these affect Quality of Life (QoL). Method: A group of 1,550 healthy Dutch participants complete a postal questionnaire including items from the Maastricht Attention and Memory Checklist (MAC). The impact of attention complaints on QoL is investigated in a subsample of 499 participants. Results: Factor analysis (N = 1,550) reveals two factors: Attention and Memory. Attention complaints are related to depressed mood, anxiety, vitality, and sleep problems that can have serious consequences for daily life functioning and QoL (n = 499). Memory complaints are related to other aspects of health, such as pain and changes in health. Conclusion: Attention complaints in the healthy population are common and related to depression, anxiety, and sleep and several aspects of QoL, such as problems with social functioning, emotional problems, and vitality.
