Functioning and Disability in Community-Living People with Perceived Cognitive Impairment or Dementia: A Mixed Methods Study using the World Health Organization Disability Assessment Schedule.

OBJECTIVE:To explore how community-living people with perceived cognitive impairment or dementia and their next-of-kin perceive functioning and disability in major life domains. METHODS:Individual interviews guided by the World Health Organization Disability Assessment Schedule (WHODAS 2.0) were conducted with 26 people with perceived cognitive impairment or dementia (age range 38-87 years) and 26 next-of-kin. Qualitative content analysis- and International Classification of Functioning, Disability, and Health (ICF) linking methods were used to analyse the transcripts. The perceived degree of disability in daily functioning was calculated and compared between people with perceived cognitive impairment or dementia and next-of-kin, using a Mann-Whitney U test. RESULTS:A total of 38 of 47 (81%) established ICF categories corresponding to WHODAS items and 38 additional International Classification of Functioning, Disability, and Health (ICF) categories describing participants perceived cognitive and physical impairments, activity limitations and participation restrictions in interaction with the environmental factors were confirmed from the transcripts. The perceived disability of people with perceived cognitive impairment or dementia was scored higher by next-of-kin (48%) than by people with perceived cognitive impairment or dementia (16%, p < 0.0001). CONCLUSION:Interviews provided a comprehensive picture of participants' perceived activity limitations and participation restrictions in the life domains cognition, mobility, self-care, getting along, life activities, and participation. For a better understanding of the impact of cognitive impairment on people's daily lives, inclusion of the perspective of the next-of-kin and the factors that hinder or facilitate daily living in the community setting is necessary.
