Objective To contrast the prevalence of mild cognitive impairment ( MCI ) as diagnosed using DSM ‐5 criteria ( DSM 5‐ MCI ) with MCI as diagnosed using Petersen's criteria (P‐ MCI ) and to explore the association of both with non‐cognitive psychopathological symptoms ( NCPS ). Method A two‐phase epidemiological screening was implemented in a population‐based sample of individuals aged 55+ ( n = 4803). The Geriatric Mental State ( GMS ) was the main psychopathological instrument used, and AGECAT was used to make psychiatric diagnoses. Research psychiatrists diagnosed DSM 5‐ MCI and P‐ MCI using operational criteria. Logistic regression models were then used to investigate the association of MCI with anxiety and depression and with NCPS . Results Weighted prevalence of DSM 5‐ MCI and P‐ MCI was, respectively, 3.72% and 7.93% for the aged 65+. NCPS were common in both MCI categories, but negative‐type symptoms such as ‘anergia’ and ‘observed slowness’ were considerably more frequent among persons with DSM 5‐ MCI . Anxiety and depression diagnostic categories were associated with both P‐ MCI and DSM 5‐ MCI , but affective‐type symptoms were mainly associated with P‐ MCI . Some negative‐type symptoms were inversely associated with P‐ MCI , and no association was observed with DSM 5‐ MCI . Conclusion The prevalence of DSM 5‐ MCI was half that of P‐ MCI . Negative‐type NCPS were more frequently and typically associated with DSM 5‐ MCI .
